    A machining center for at least one of a drilling or milling operation. The machining center includes a machine frame at which an outrigger is attached, with a tool spindle, driveable to execute stroke movements and rotary movements, being mounted to the outrigger. The tool spindle is adapted to be moved from an end position, in alignment with a tool carrier present in the tool magazine and connectible to the tool spindle, axially for being coupled to the tool carrier and then further movable axially for machining of workpieces. The tool spindle is rotatably mounted at a slide arranged at the outrigger and guided along a straight guide extending in parallel to an axis of rotation of the tool spindle. The slide serves for axial movement of the tool spindle for executing axial strokes intended for workpiece machining and for an exchange of a tool carrier. The slide has a zone through which the tool spindle extends, which zone may pass through a gap of the tool magazine. Upon each tool carrier change, the gap may be engaged by the respective tool carrier to be coupled to the tool spindle, which tool carrier is carried by a magazine connecting member in order to enable a coupling to the tool spindle. The straight guide for the slide is arranged at a spacing from the zone of the machine frame carrying the outrigger.

    专利说明:

    The invention relates to a machine tool industry, namely to machine tools with an automatic tool change. A metal-cutting machine with an automatic tool changer is known, on the frame of which a console is mounted, on which a spindle is movable relative to the console and an instrumental magazine with instrumental mandrels moving along a concentric magazine guide, and a groove in which there is a movable guide element, and the spindle is mounted so that it can engage with the tool holder on the intermediate element LTJ. However, in a known machine, the rigidity of the spindle assembly is insufficient, which is especially manifested in heavy milling and boring work. The purpose of the invention is to improve the quality of processing. . To this end, the metal cutting mill with an automatic tool changer, on the frame of which a console is installed, on which the spindle is movable relative to the console and a tool magazine with tool holders moving along a concentric magazine guide, and a groove is made in the guide magazines. In which the movable guide element is located, and the spindle is mounted with the possibility of coupling with the tool holder on the intermediate element, it is provided with The axles are parallel to the longitudinal axis of the spindle, and the slide is mounted to pass through the groove of the tool magazine, the magazine is located on the console between the slide rail and the frame of the machine, The slide protrudes beyond the machine console in the direction of the device for securing the workpiece. The intermediate element is designed as two diametrically opposite one another segments with guides, which are a continuation of the magazine guides. Moreover, the septations are mounted on additionally introduced spring-loaded support rods, located in the slide, directly in the direction of their supply. The motor for driving the tool spindle is mounted on a slide, and the motor for feeding the slide is fixedly mounted on a cantilever which is replaceable. The machine is equipped with a clamping device, a vom for fixing the slide along the entire length of the guide, and at least one of the tool mandrels is made in the form of a multi-spindle tool head. In this case, the slides have a protrusion beyond the plane of the guides, which are located on the slide, in the direction of the device for clamping the workpiece. FIG. 1 shows a cutting machine, general view; in fig. 2 console structures; in fig. 3 shows section A-A in FIG. 2; in fig. 4 view B in FIG. 1. The metal-cutting machine has a frame 1 with a bed 2, guides 3 for moving the cantilever 4 are made on a vertical stand 5. The cantilever is moved from a separate drive, for example, in the form of a hydraulic cylinder. On the table 6 of the machine, the workpiece 7 is clamped. At the bottom of the console there is a magazine 8, in which there are tool holders 9 in the form of a sleeve with a groove 10 —in outer diameter and flange 11. In the caliper 9, the tool holder 13 s is mounted for rotation on the rolling bearing 12 the tool 14, the Cone .15 of the tool holder 13 has the shape of the hole 16 in the tool spindle 17. In the console body 18, there are two concentric rings 19 and 20 of the magazine 8, the upper planes of which form slip tracks 21 having the shape of the arc of a circle, with the flange 11 of the caliper 9 adjacent to these tracks 21 slide. The concentric rings 19 and 20 have a passage 22 and 23 located on the shop section located at the console. - GOOCHO with concentric rings 19 and 20 is located an asterisk 24 with a notch 25 for gripping the soup-. port 9, which is rotated by a special drive. 3 A slide 26 with an instrumental spindle 17 moves vertically along the guiding surfaces 27-29 of the slide, made in the housing 30 of the slide 2b and the slats 31. The force closure of the housing 30 slides inside the console 4 Mostly takes place along the plane 32 .. The displacement of the slide 26 runs from the electric motor 33 through the nut.34 and screw 35, and the rotation of the inetrumental spindle 17 from the electric motor 36 through the box of 37 speeds. Section 38 of the sled 26, the cage which passes the instrumental spindle 17 and which projects in the direction of the vertical pillar 5, is designed in such a way that it can pass through the passage 22 and 23 of the magazine 8, formed by the rings 19 and 20, with a gap. The position in passage 23 is intermediate 39, consisting of segments 40 and 41 spaced from each other. Segment 40 rests on two vertical support rods 42, and segment 41 rests on one rod 43. Erase 42 and 43 are spring-loaded 44..At the top The position of the segment 40 and 41 is adjacent to the fixed lateral stops 45. The narrow side projections of the segments on the underside of the corresponding rings 19 and 20. In this case, the notches 46 of the segments 40 and 41 are integral with the backs of the slip 21. The intermediate link 39 can carrying only one tool soup port 9, - Clamps 47 are provided in the slide 26 for clamping the slide in any working position, interacting with the plane 48. grooves made in the console housing 4. Clamping devices 47 are filled in the form of a hydraulic cylinder with pistons 49 and 50 with an inclined working surface. At the bottom end of the spindle, a spring-loaded gripping pin 51 is installed, interacting with a groove made in the upper end face of each tool holder 13. The slide 26 is equipped with sections 52 protruding beyond the plane toward the center: in the direction of the table 6. 64 The machine works as follows. When the slide 26 is located in the upper position, the planes of the notches 46 are one. Integral with the slide tracks 21, the sprocket 24 turns on its drive and the tool holder 9 with the necessary tool moves to the intermediate 39. The slide 26 with the tool spindle 17 moves down from the drive to table 6. In this exciting, pin 51 falls into a groove made in the end of the tool holder 13, which ensures the orientation of the spindle 17 and the tool holder 13. If the exciting pin 51 does not match the groove m of the tool holder, it rests against the upper end of the tool holder and, under the action of further movement of the slide, is sunk into the CBoei socket. Next, the spindle 17 is rotated to the desired angle by the action of the spring of the gripping pin 51. This ensures the relative orientation of the tool spindle 17 and the tool holder 13. Further movement of the slide provides full gripping of the tool-tool cone 15 in the spindle and its fixation in a known manner, for example, with balls. Next, the slide 26 is moved together with the tool holder 13, the support 9 and the segments 40 and 41 to the machined workpiece 7. After processing is completed, the tool shaft and the tool holder 13 are lifted with the support 9 and the tool holder 13, unlocking the tool holder in the spindle, searching A new slide 9 with tool holder 13. Then the cycle repeats. Equipping the cutting machine with a slide under the machine spindle, installed with the possibility of passing through the tool magazine groove, and supplying it with a clamping device for fixing the slide having guides beyond the plane of the guides in the direction of the device for clamping workpieces, can significantly increase the rigidity of the machine's SHED system, leads to higher quality processing.
