    1500433 Adjusting and testing fuel injection pumps ROBERT BOSCH GmbH 26 March 1975 [1 April 1974] 12546/75 Heading F1A The delivery quantity of an in-line fuel injection pump 10 is adjusted during the final assembly thereof by an arrangement comprising a delivery quantity measuring device 84 for measuring and indicating the quantity of fuel delivered from a given cylinder, and adjusting tool 28 movable to cause angular adjustment of the cylinder's liner and thereby adjust the quantity delivered, an adjusting motor 53 for driving the tool 28, and a control device 54 for controlling the motor 53. In the embodiment shown each pump cylinder liner is adjustable by an individual adjusting tool 28 driven by a respective motor 53, but alternatively a single adjusting tool 28 movable to different locations may be used to adjust the cylinder liners in turn. Each adjusting tool 28 is in the form of a lever having at one end a projection 30 received in a groove 31 in flange 32 on a respective cylinder liner. The opposite end of each adjusting tool lever 28 has a groove 46 in which is received a worm 48 on a respective worm-wheel 49. The worm-wheels 49 are rotatably supported on a shaft 55 and are driven by their adjusting motors 53 through chains 51 connecting gears 52 on the motor to gears 50 on the worm-wheels 49. To allow the fuel injection pump and a carrier 11 therefore to be accurately located in a clamping device 12, without interference from the tools 28; the shaft 55, motors 53 and tools 28 are mounted between bearing plates 25 pivotable on a shaft 18. After clamping of the pump, a piston and cylinder motor 19, 20 is actuated to cause the worms 48 to engage the grooves 46. In the clamped position the cam shaft 40 of the pump is connected through a clutch 63 to a drive unit 62. The control device 54 has a manual control 89 or an automatic control in the form of a process computer 80 fed with signals from a tachogenerator 70, the quantity measuring device 84 and the pump's quantity regulating control rack 78. These signals are compared with desired values supplied to the computer by an input device 81 controlled by punched cards. Signals dependent on the difference between the actual and desired delivery quantities for the speed and rack position selected are sent to the control device 54, the latter operating to cause each motor 53 to rotate by the exact amount necessary to achieve the required delivery. Bolts 35 holding the flanges 32 in position are initially tightened by an amount which allows adjustment of the flanges, whereafter they are fully tightened by a screwing device 90.

    This invention relates to test benches for fuel equipment. There are known devices for regulating the cycle supply of multi-sectional fuel pumps, which contain devices for assembling and disassembling a plunger pump with a spool-type pump discharge valve, the sleeves of which are fixed in the mounting position by a mounting flange fixed to the end of the pump and have the possibility of turning to adjust the cycle supply, : and cyclic flow meter 1. The known devices by their design do not allow adjustment and test of the pump to the position FAST. The object of the present invention is to eliminate the above disadvantages, namely the reduction of the regulation time. This goal is achieved by connecting the regulator with mechanical control and drive to one pumping section, which engages with the flange of the fuel pump or with the transmission link, which is connected with the mounting flange or sleeve, and the drive is connected to an auxiliary engine connected with control unit. The auxiliary engine can be made in the form of a stepper motor, and the drive can be made in the form of a worm wheel with an adjusting screw that meshes with the regulator. The worm gear is equipped with a pin and is connected with a stepper motor through a chain. The worm gear is installed in the housing of the regulating device with two thrust bearings and with a rotating support in the form of a radial subframe. The regulator is made in the form of a two-armed lever. The regulator is integrated with the drive and auxiliary engine into a regulating device located, which can be rotated in the housing. .In FIG. 1 shows a device with a fixed corresponding fuel pump in a simplified form, one embodiment; in fig. 2 is a partial sectional view of a fuel Lacos driven by a driving unit, with a device adjusting device, including a regulating device 1m, a rearranging drive and an executive engine; FIG. 3 is a partial section A-A in FIG. 2; in fig. 4 partial resolution of the second embodiment. The multi-plunger fuel pump (see Fig. 1) is screwed to the fixture 2 by means of this fixture and clamped in the fixing assembly fixture 3 by means of this fixture. Fixing-disassembling fixture 3 contains fastening teeth 4, which in the device according to the invention are driven by working cylinders in a known manner. The assembly-disassembly device 3 is fixed on the functional plate 5 of the housing b of the device, in the same way as the two racks of the bearing 7 of the regulating device, one of which is shown in FIG. 1-3. The adjusting device 8 contains the shaft 9 installed in bearing posts 7, which serves as a pivot for the adjusting device 8. The adjusting device 8 rotates into the working position shown in the drawing by the actuating engine 10, which in the following example is designed as a hydraulic cylinder-piston unit, Servoporsion 11, As can be seen, in particular, from FIGS. 2 and 3, designated as a working position in FIGS. 2 and 3, the swing position of the adjusting device and its non-displayed non-working on the drawing Positioning is regulated by the bore 12 of the restrictive bearing 13, since the axis 14, which is rigidly connected with the adjusting device 8, simultaneously serves as the limiting stop and counter support for the servo-piston 11 of the executive engine 10. The housing of the regulating device 8 consists mainly of two base plates 15 of the subframe (only one is shown), of two crossbars 16 and 17, in which regulating bodies 18 are installed, made in the form of two-arm levers. The device is fully automated, therefore, as can be seen in FIG. 3, each pumping element 19 of a regular fuel pump 1 corresponds to a regulating member 18 The device can be equipped only with one regulating member 18, which together with the appropriately modified housing 20 can be movably installed in the axial direction of the fuel pump or in the axial direction of the shaft 9 with the ability to move on the latter and for adjustment by the pump section in the appropriate working position s. Regulator 18 (see Fig. 1, 2 and 3), with its jumper-shaped hub 21, located on one shoulder of the lever 22, interacts with the engaging groove 23 at the limiting perimeter of the mounting flange d4 for the pump section of the fuel pump 1, V the housing 25 of the fuel pump 1 is inserted and with the help of two screws 26 is pressed against the upper end side 27 of the housing 25 of the cylinder bushing 28. In the cylinder bushing 28 with the possibility of axial and rotational movement also, in a known manner, plunger 29 provided with at least at least one oblique cut-off edge 30, and the cut-off cut-off edge 30 interacts with a cut-off opening 31 in the wall of the cylinder sleeve 28. The axial movements and raising of the plunger 29 are performed by the driving cam roller 32. However, the rotational movements of the plunger 29 to randomly vary the flow rate of the supplied fuel are caused by a known method shown by the dotted line rail 33, the control movements of which pass parallel to the longitudinal axis of the fuel pump 1 or the drive cam roller 32 and are converted by shifting the vodom vraschatepnye during movement of the plunger 29. As a result of the rotational movement of the plunger 29 varies the relative position of the oblique cut-off edge 30 on referring to the isolation port 31 and thus fuel consumption, feed pump section corresponding to the fuel pump for one Wake up. In order for the fuel pumps, made in the form of a series of pumps, each plunger 29, when the rack position is set, supplies the same amount of fuel in one lift, it is necessary to set all the pump sections of the fuel pump 1 to the same flow rate for a firmly installed position of the rail 33. In fuel pumps of the described construction, this is accomplished by rotating the cylinder sleeve 28 within a limited angular range. For this purpose, the mounting flange 24, which is rigidly connected to the cylinder sleeve 28, has two elongated holes 34 through which the screws 26 are used to secure the pump section. Inside the pump section, made in the form of a flange element, in the continuation of the hole 35, leading. the plunger 29, inserted pressure valve 36, which is sealed and stationary. It is contracted by the tip 37 of the injection pipeline with the cylindrical bushing 28 in the position shown in the drawing. The described pump design is particularly suitable for the automated adjustment of the main supply mode according to the proposed invention.
    Regulator 18, installed in regulating device 8 or in its crossbars 16 and 17, by the second arm of the lever 38, not facing the first arm of the lever 22, is equipped with a protrusion 21, is connected to a force and kinematic closure with a rearranging actuator 39, which consists mainly from the worm gear 40, equipped with a shifting screw 41, the shifting screw 41 interacting with the groove 42 of the regulator 18. The worm gear 40 has a gear 43 and through the chain 44 is connected with the driving gear 45, which serves The linear actuator of the electromotive stepper motor 46 controlled, as can be seen from FIG. 1, control device 47,
    FIG. 1-3, there are two identical, actuating, respectively, one regulator body 18, rearranging actuator 39, driven through chains 44, respectively, one of the stepper motors 46 mounted on the base plate 15 of the bearing with spatial displacement relative to each other.
    The second base plate under the mirror is located symmetrically depicted in FIG. 1-3 and carries at least two equally installed actuators and rearranging drives, so that this device is designed for automatic adjustment of the four-plunger variable fuel pump. By placing more than two stepper motors on one bearing base plate or mounting another bearing base plate, the described device can also be used for larger fuel pumps with a large number of pump sections.
    All the worm gears 40 connected with the force and kinematic closures, respectively, with one regulator 18, are mounted on a common axis 48, which in turn is fixed in the base plates 15 of the bearing of the adjusting device 8. Each worm gear 40 - updated on the axis 48 with a radial bearing 49 serving as a rotating support, and contains two supporting thrust bearings 50, through which it directly or indirectly rests on the housing 20 of the adjusting device 8. Between every two, m adjacent h With worm wheels 40, a common thrust bearing 50 is mounted for reasons of cost and work space. One bearing base plate, shown in the drawing, is rigidly connected to the stop 51, on which the fuel pump 1 rests with one of its end surface 52, so that when adjusting the cylinder sleeves 28, the stop 51 perceives the shifting forces introduced into the fuel pump 1. As in more detail described further, the permutational forces act only in the direction towards the stop 51. Digital
     A rotary 53 in FIG. 1 is a position sensor, made in the form of a limit switch, which sends a CHI to the control device 47 if, after turning the adjusting device 8 with the help of an actuator 10 or its servo piston 11 around the shaft 9, which serves as the axis of its rotation , adjusting device 8, shown in the drawing
    0 a working position in which the regulators 18 are engaged with the mounting flanges 24 of the fuel pump 1. The position signal coming out of the position sensor 53 is fed through the wire 54 into the device 47
    5, and to this wire 54, other position signals, not shown in fig. 1-4 in more detail of the switches and sensors of the position of the regulating device 8, the devices 3 for the assembly-disassembly and the drive unit 57. For example, position signals from the sensors are transmitted through the supply line 55
    The 5 positions that report the corresponding extreme positions of the worm gear 40 equipped with the shifting screw 41, and the supply line 56 transmit position signals that indicate the correct position of the fixture 2 for securing the product inside the assembly-disassembly fixture 3 teeth 4 and the drive readiness of the quick-release coupler 58 (see Fig. 3) of the drive unit 57. The quick-release coupler 58 clamps the end of the shaft 59, which is part of a torsional stiff but elastic coupling bend 60 connected to the drive cam roller 32 of the fuel pump 1.
    As can be seen from the simplified diagram in FIG. 1, drive unit 57
    5 is provided with a rotation speed regulating device 61, which is actuated, optionally, with manual speed control device 62 or via line 63
    0 control circuit in the automatic mode of operation of the device 47 control. A drive unit 57, which preferably contains an asynchronous motor controlled by thyristors, drives the feed pump 64 and preferably the inductive motor. rotation speed sensor 65. The delivery pump 64 through the suction pipe b sucks the fuel from the eSack 67 and, via the injection pipe, water 68 supplies it to the low pressure chamber 69 of the fuel pump 1. As can be seen from FIG. 2, the fuel is fed from the discharge pipe 68 to the low pressure chamber 69 through pipe 70, which in the mode shown in FIG. 2, an example of a variant of the fuel pump 1 is located on the right ETON of the pump, however With a different installation of the pump on the engine it can also be on the opposite side, like this, with a tubular 71, with a colored dash-dotted line. In the described device, the regulator 18 is inserted between the worm gear 40 and the mounting flange 24, since with the position of the socket 71, directing the adjusting flange 24 with the aid of the reset screw 41 of the worm gear 40 would not be possible. Shown in FIG. 2, the rail by hand or in a fully automated device using actuating element 72 is driven to the position of the rail necessary and provided for adjustments of the fuel pump, with actuator 72 controlled by control device 47 via control wire 73, 63 of control circuit. and the excited position of the rail 33 using the position sensor 74 enters the wire 7-5 to the computing circuit 76 to control the process. This computer for controlling the process, equipped with a driver 77, along with the rail position signal, receives a rotation speed signal via the wire 78 with a rotation speed sensor 65, and a measurement data of the device 80 via the wire 79 to measure performance. For manual maintenance of these machines, rotation speed indicator 65 or wire 78 is connected, rotation speed digital indicator 81 is connected, and device 80 for measuring performance consists of one hf 82 for measuring the flow rate and at the same time measuring pump section of one digital Indicator 83 consumption, KoVoipSft requires a D1P device check and semi-automatic mode Maij and also serves as a flow sensor for instrument 47 control. If the computing machine for controlling the process does not apply,, - Piggyg1GshchaNoEs JSf 7S and 797strob: please use: 6s6p1Only to the control unit 47. As the wire 84 depicted by a dash-dotted line shows, the individual values for controlling the device, entered into the master device 77, preferably from a punched card, are directly entered into the control device 47. For the semi-automatic operation mode, the control unit is equipped with an additional manual control device 85, with which it is possible to manually control all the working steps of the corresponding control method, which will be described in more detail later, it contains digital indicators for all functions of the device. The extent to which the rotational speed control device 62 and the digital rotational speed indicator 81, as well as the display indicator 83, are integrated with this manual control device for the invention is not essential and is at the discretion of the skilled person. 86 in FIG. 1 is marked with a screwdriver, which is also driven by the control device 47 and serves to tighten the screws 26, which prior to adjustment of the cylinder sleeve 28 are tightened only with an incomplete torque, which does not reduce the performance of the pump and allow mechanical turning of the mounting flange 24 or the cylinder sleeve 28 and only after adjustment - with a final holding torque. To reduce the cycle time of the adjustment process inside the device, it may also be beneficial to place one such screw driver on the assembly line in front of the device and behind it. A device for measuring the flow rate of a performance measuring device is connected via a discharge pipe 87 to a pipe coupling 88 (see Fig. 1). Pipe coupler 88 is designed as a high-speed mounted coupling or an automated / clamping device controlled by a servo piston. A second embodiment of the invention according to FIG. 4 differs from that shown in FIG. 1-3 alternatively, the regulator 18 of the regulating device 8 does not interact directly with its jumper-shaped protrusion 21c with the groove 23 or the mounting flange 24 of the fuel pump 1, but enters the groove 89 of the transmission link 90 of the fuel pump, designated 91. The gear link 90 includes the adjusting the flange 92 of this fuel pump 91, which is not equipped specifically for regulation, and, like the pump 1 according to FIG. 1-3, the installation flange 92 is rigidly connected to the cylinder sleeve93.
    The described device serves for machine or mechanized adjustment of the performance of individual pump sections of fuel pumps 1 or 91, made in the form of a row pump. This process is also referred to as an adjustment, since at a given and fixed position of the rail 33, the fuel consumption of each individual section of the fuel pump is set to the same flow within the specified tolerance limits. The most important measuring point for such a feed adjustment is the so-called full load flow, measured at the rotational speed of the fuel pump at full load. To compensate or expose the technological defects of the pump sections, two more measurement points are set at the lower limit of idle speed regulation and the upper limit of adjusting the idle speed.
    The following describes the principle of the device according to the invention based on FIG. 1-3 for automatically proceeding control of the supply of the pumping sections of the fuel pump 1, which is controlled by the computer 76 for controlling the process and the control unit 47.
    The fuel pump, mounted on fixture 2 of the MJIH device, is assembled by means of an assembly conveyor in front of the device into assembly-disassembly device 3 and clamped in it by fastening teeth 4. Simultaneously using a quick-release coupling 58 (Fig. H) the drive unit 57 is connected to the torsional stiffness of the end of the shaft 59, coupled to the 60 G coupling by the driving cam roller 32 of the fuel pump 1. Thereafter, the discharge pipes 87 provided for each pump section are connected their are pipe couplings 88 to the tip of the injection duct 37, discharge line 68 is connected with a branch pipe 70, namely simultaneously with the not shown in the drawing outlet line which is connected at the same level at the site of attachment of the pump 1 and removes too much fuel supplied in
    tank 67. After the actuating member 72 has been connected with the rail 33 to the position sensor 74, the adjusting device B is turned into the operating position shown in the drawing, in which the regulators 18 interact with the grooves 23 of the mounting flanges 24, The device is ready to work. It is advisable
    but tightening the screws 26 already on the assembly conveyor to an incomplete torque, which, as compared with the final torque retention, is reduced, does not impair the flow, but allows me
    turn mounting flange. Particularly beneficial was an incomplete torque of about 0.4 kgf-m.
    As can be seen from FIG. 3, the fuel pump abuts its face 52 to the stop 51 and it is advantageous that all the mounting flanges 24 in the delivery state are in the extreme position bounded by the longitudinal apertures 5 34 and caused by the left rotation (i.e. arrows). Since, in the usual case, the mounting flanges 24 are approximately in their middle position, the adjusting flange 18 rotates the mounting flange 24 in the clockwise direction, so that the stop 51 senses the shifting forces
    5 entered into the pump 1.
    Now the process of measuring and adjusting the performance starts directly, through the control circuit line 63, the device 61, which controls the rotation speed, receives from the control device 47 a signal by which the drive unit 57 drives the fuel
    , pump 1 with a number of revolutions at full load, when it is the number of revolutions
    5 has been achieved, the data obtained from continuous performance measurement using flow measuring instruments .82 are inputted via wire 79 to flow sensors in
    0 computer 76 for controlling the process. This computer is programmed to. the full program of regulation and with the help of punched cards receives through the master
    5, the device 77 regulates and changes data relevant to the respective pump - Based on a comparison of the measured data with the specified values of the instrument
    0 47 so controls the stepper motors 46 that, as a result of the rotation of the worm gear 40, the mounting flanges 24 are turned by the regulating members 18 almost to its
    5 position corresponding to the specified performance. The measured capacity of the pump sections is now stored in the computer 76 for controlling the process.
    0 To measure the second measuring point, the drive unit 57 accelerates the fuel pump 1 to the upper limit of the speed control at idle, and the actuator
    5 72 sets rail 33 to the appropriate position. The performance measured in this position and the number of revolutions is also memorized by 8 computational 76 lines to control the process. As a third measuring point, there can be a rotation and a path to move the rail at lower idle. The measured output of the merge, the flaw, will also be stored with, and in the quality of the next step, the squeezing machine for controlling the process calculates the optimization. In this case, the computer decides whether, at the measured performance values, such adjustment of the flanges is possible, at which performance is within tolerance at all three measurement points. If the computational system makes a negative decision, the process and measure is stopped, and the fuel pump 1 is dismantled for mid-level or major repairs. The error log compiled by the computer allows you to quickly find a damaged or damaged pump sections. If the calculator Yaa: the machine makes a positive decision, then using the appropriate control signals, the mounting flanges 24 are set to their predetermined position. In this position, one measuring point or all of the measuring points esh is measured and monitored and when error-free adjustment the unit 57 is turned off, the connections of pipelines 68 and 87 are loosened, the adjusting device 8 is turned as a result of lowering the servo motor 13 of the actuator, -the engine 10 From the working position shown in the drawing to its inoperative position, the high-speed fastener 58 of the axle unit. 57 is loosened, the lugs 4 are loosened and the fuel pump 1 with its device 2 for securing the product is pulled out of the device 3 for disassembling assembly. The described technological operations, based on a fully automated adjustment process, can be triggered by the device 47 # oy days ago And in a semi-automatic mode, the operator inserting individual technological operations into the control device using the manual control device 85. The number of revolutions of the drive is also preliminarily selected in this manual control device or set on the speed control device 62 connected to the speed control device 61. Also, the digital speed indicator 81 shows the actual number o6opOTOs, the indicator. 83, which simultaneously serves as a flow sensor, indicates the flow rate of the supplied fuel, and other operating positions, such as the operating position of the regulating device 8, shown in FIG. 1-3 and signaled to the control device 47 are indicated in the manual control device 85 by known and therefore not shown in more detail warning lamps. Instead of calculating the optimization for controlling the stepper motors 46 performed by the computing machine 76 to control the process, the operator takes the performed steps of the stepping motors 46 from the table and inputs the corresponding value to the manual control device 85. During the rotation of the mounting flanges 24, it is necessary to pay special attention to the fact that in the first adjustment process the specified pull-out value is not exceeded, since retraction against the adjustment direction would be unacceptable or unprofitable due to gaps in individual actuators x and established only sodnoe st.oroyy. The selected equipment of the regulating device with 8 stepper motors 46 and the screw drive, wheel 40 through chains 44 turned out to be an extremely simple and at the same time advantageous solution. Stepper motors can be controlled by precisely defined control signals and do not need to be feedback of the position taken, and circuits 44 provide for a cheap and non-slip transmission of significant switching forces. Due to the slow motion of the rotational motion of the stepper motors. With the help of the drive gear 45 and the gear 43 of the worm gear 40 and thanks to the shifting auger 41, which has a very small step, it is possible to precisely set the regulating movement performed by the regulator 18 on the mounting flange 24, and the necessary high shifting forces can be applied. Instead of the drive from the stepper motor 46 and the worm gear 40, another known mechanical or hydropic drive can be selected for the regulator 18. For the limited working space in the axial direction of the driving cam roller 32 Hacota, defined by the mutual distance between the pump sections, the possibilities of drive selection are very limited, therefore the chosen arrangement has proven to be particularly advantageous.
