    In a metrological or other sensitive apparatus, the transducer or other operative member (22) is mounted on a support structure (14 to 18) which is carried on a chassis (2) by a first set of dampers or isolating means (10) and the chassis (2) is mounted on the floor by a second set of dampers or isolating means (6). The two sets (10, 6) have different natural frequencies and the first set (10) is arranged so that any vibration of the support structure tends to be rotational centred in the zone of operation (21) of the transducer or other member. This is achieved by arranging that the stiffness of the first set of dampers (10) is higher in the direction (24) passing through the zone of operation (21) than in the transverse direction.

    专利说明:

    The invention relates to a measurement technique and can be used in such metrological devices as a speed measurement system, an angle measurement system, in a device for measuring profile errors, including measurement of roundness, linearity and surface structure.
    The purpose of the invention is to increase efficiency.
    Figure 1 schematically shows the device, a general view; figure 2 is the same, side view; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1; figure 5 - view 8 in figure 4.
    A device for performing metrological operations at an object contains a frame 1 having four supports 2 (three supports are shown in Fig. 1), each of the supports has a shock absorber 3 isolating vibration and supporting all devices transferring its load to the floor of the room (not shown). Base 4 is mounted on frame 1 and fastened with additional four vibration isolating shock absorbers 5 and has on itself a turntable b driven by a motor b on which a part (not shown) to be measured is mounted, and a vertical column 7, Driven from the motor, the carriage 8 can move in the vertical direction (indicated by arrow D) on column 7. On the carriage 8 there is a lever 9, which is driven from the motor in the horizontal direction (arrow D) and carries the sensor 10, Commercially locking nib 11 adapted for engagement with the surface of the workpiece, which is mounted on the turntable 6. The pen 11 is full You are a function of measuring various characteristics (roundness, straightness or roughness) of the workpiece. As a result of the vertical movement of the carriage 8, the horizontal movement of the lever 9, the tip of the fixing pen 11 can move in any direction within the rectangular area 12 of operation.
    Fork hinge 13 provides movement of the sensor 10 and the locking pen 11 relative to the lever 9. Fork hinge 13 is mounted so that the tip of the locking pen 11 is always in the zone 12 of operation.
    The shock absorber 3 consists of an elastic cushion 14, which is recommended to be made of neoprene rubber. The cushion 14 rests on the floor 15 of the room and which is fixed inside the bell-shaped body 16. The body 16 is fixed to the plate 17, which is part of the support 2. The body 16 is fixed to the plate 17 by means of a bolt 18 having a lock nut 19, with which You can adjust the position of the cushion 14 relative to the housing 16.
    Each shock absorber 5 is fixed between the bracket 20 of the frame 1, having a bearing surface 21, which is located at a right angle relative to the longitudinal axis 22 of the shock absorber 5 and the bracket 23 of the turntable 6, which has a bearing surface 24 that is parallel to the surface 21.
    The shock absorber (FIGS. 4 and 5) consists of an elastic cushion in the shape of a truncated cone 25, which is recommended to be made of chesprene rubber and the rigidity in the axial direction is greater than its rigidity in the transverse direction. A ratio of these stiffnesses of 5: 1 is preferred. The washer 26 is attached to / to it (me) the base of the truncated cone 25, the pin 27 is welded to the washer 26 and passes through the hole 28, made in the bracket 20, of a lower diameter compared to the pin 27, to allow the necessary adjustment. A nut 29 placed on the pin 27 is used to secure the washer 26 to the surface 21 of the bracket 20. The plate 30 is attached to the lower base of the split cone 25 and with the help of the pin 31 passing through the hole 32 to the surface 24 of the bracket 23.
    The device works as follows.
    The workpiece, the surface to be measured, is placed on the turntable b, the carriage 8 and the lever Q are moved so that the surface of the workpiece is in direct contact with the fixing pen 11, whereby the sensor 10 generates a signal that contains information about surface features of the workpiece. The vibration isolating dampers 3 and 5 are used to eliminate the likelihood of the transmission of external vibration to the sensor 10 or the locking pen 11. The natural frequency at which frame 1 can oscillate on vibration isolating shock absorbers 3 should be different from the natural frequency on which the base 4 can oscillate on vibration isolating dampers 5, i.e. the natural frequency of the shock absorbers 3 must be less than the natural frequency of the shock absorbers 5. The ratio range of these frequencies is (1: 1.5) (1: 2).
    In addition, the shock absorber 5 has a higher stiffness along the longitudinal axis passing through the zone 12 of the operation of the fixing pen 11 as compared to the stiffness in the direction perpendicular to the longitudinal axis, a ratio of these two stiffnesses of 5: 1 is preferred. All lines pass through a point (Figures 1 and 2) located within the zone 12 of operation and essentially in the center of this zone. When all these conditions are met, the vibrations transmitted from the floor in the shock absorbers 5 tend to form a slight rotational oscillation of the table 6 around a point in the zone 12 of the fixing pen 11, due to which the influence of this vibration is very small.
