Description

Technical Field

[0001] The utility model relates to the field of automated production lines, in particular to an automatic processing device for an automobile shock absorber piston production line. Background Art

[0002] The automobile shock absorber piston is an important component of the automobile shock absorber. It is located inside the shock absorber and is responsible for controlling the vibration and rebound caused by uneven road conditions when the vehicle is driving.

[0003] Currently, automated devices are used in the manufacturing of pistons, but the existing automated piston production devices are relatively inefficient. Usually, a robot is responsible for clamping the piston to be processed to the processing position, then waiting for the processing to be completed to take out the finished piston and send it to the discharge position, and then moving to the material taking position to clamp the piston to be processed. Such a setting requires waiting during processing, and the lathe needs to wait again for the robot to re-clamp and replace the processed piston, which is relatively inefficient. Therefore, a highly efficient piston processing device is needed. Summary of the invention

[0004] The problem to be solved by the utility model is: to solve the problem that the existing piston automatic production device is relatively low in efficiency, and to provide an automatic piston processing device which can complete the process of taking out the finished piston and placing the piston to be processed in one step to reduce the waiting time.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: an automatic processing device for an automobile shock absorber piston production line, comprising a lathe, an axial translation mechanism, a turning tool assembly, and a clamping and rotating mechanism, wherein the axial translation mechanism comprises a first slider, a first drive, and a first slide rail, wherein the first slide rail is arranged along the axial direction of the lathe, and the first drive drives the first slider to move axially on the first slide rail, and a manipulator frame is fixedly connected to the first slider, and a first cylinder and a second cylinder are arranged in parallel at the lower end of the manipulator frame, and the ejection end of the first cylinder is fixedly connected to the first manipulator, and the ejection end of the second cylinder is fixedly connected to the second manipulator; a material taking position and a material discharging position are arranged at the outer end of the axial translation mechanism, a processing position is arranged in the lathe, and the inner end of the axial translation mechanism is arranged in the lathe, and the clamping and rotating mechanism is arranged at the axial ends of the processing position, and the turning tool assembly is arranged on both radial sides of the processing position and moves in a longitudinal direction perpendicular to the axial direction;

[0006] When the manipulator frame moves to the outer end of the axial translation mechanism, the first manipulator is located at the material taking position to clamp the piston to be processed, and the second manipulator is located at the material discharging position to place the processed piston; when the manipulator frame moves to the inner end, the clamping and rotating mechanism is released, the second manipulator retrieves the processed piston from the processing position, the first manipulator places the piston to be processed at the processing position, the clamping and rotating mechanism clamps the piston to be processed and drives it to rotate, the manipulator frame moves vertically to the top of the processing position, the turning tool assembly cuts the piston in a direction perpendicular to the axis of the lathe, and the manipulator frame moves axially to the outer end of the axial translation mechanism.

[0007] After the processed piston is retrieved by the second robot, the first robot places the processed piston to the processing position. The first and second robots exit the processing position at the same time, and the lathe starts processing. At the same time, the first and second robots move to the picking and unloading positions to complete the picking and unloading actions, and then move to the processing position to repeat the action. Compared with the previous robot waiting for the processing to be completed to retrieve the processed piston, then placing the processed piston to the unloading position, and then moving to the picking position to replace the processed piston and placing it at the processing position, many redundant movements are merged, steps are reduced, and efficiency is improved.

[0008] The turning tool assembly includes a second slider, a second drive, a second slide rail, and the second slider is fixedly connected to the turning tool holder. The first turning tool and the second turning tool are radially arranged below the clamping and rotating mechanism, and the first turning tool and the second turning tool are fixedly connected to the turning tool holder. The second drive drives the second slider to move longitudinally on the second slide rail perpendicular to the axial direction. Compared with the prior art, the utility model has two turning tools arranged under the main shaft of the lathe, one for rough turning and the other for fine turning. The turning tool mounting seat is controlled by a servo motor to move longitudinally on the turning tool slide rail, driving the two turning tools to follow the preset path of the program, thereby increasing the life of the turning tools and improving dimensional accuracy.

[0009] The specific clamping and rotating mechanism includes a spindle head, a push rod, and a third cylinder. The spindle head is axially rotatably connected to the lathe, one end of the push rod is axially opposite to the spindle head, and the other end is rotatably connected to the sliding frame. The third cylinder is fixed on the lathe, and the third cylinder drives the push rod on the sliding frame to move axially.

[0010] A locating pin is axially arranged on the spindle head, a locating hole for inserting the locating pin is provided on the push rod, and a socket for passing the locating pin is provided at the center of the piston. Compared with the prior art, the utility model facilitates the positioning of the piston by arranging a locating pin at the center of the spindle head. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1 , 4 5. An automatic processing device for automobile shock absorber piston production line, comprising several important components such as a lathe 10, an axial translation mechanism 11, a turning tool assembly 12 and a clamping and rotating mechanism 13. The axial translation mechanism 11 can translate in the axial direction of the lathe 10, and comprises a first slider 14, a first drive 15 and a first slide rail 16. The first slide rail 16 is arranged along the axial direction of the lathe 10, and the first drive 15 drives the first slider 14 to make axial movement on the first slide rail 16. The first slider 14 is connected to a manipulator frame 17, and the lower end of the manipulator frame 17 is equipped with a first cylinder 18 and a second cylinder 19. The ejection end of the first cylinder 18 is fixedly connected to the first manipulator 34, and the ejection end of the second cylinder 19 is fixedly connected to the second manipulator 35. The clamping and rotating mechanism 13 is arranged at the axial ends of the processing position 22, and can realize the function of clamping and rotating the piston to be processed. The turning tool assembly 12 is arranged on both radial sides of the processing position 22, and can perform cutting processing on the piston.

[0022] The following are the operating steps of the automatic processing device for automobile shock absorber piston production line:

[0023] The first drive drives the manipulator frame 17 to move to the outer end of the axial translation mechanism 11. At this time, the first manipulator 34 is located at the material taking position 20, and the first manipulator 34 will clamp the piston to be processed. At this time, the second manipulator 35 is located at the material discharging position 21, and the second manipulator 35 places the processed piston at the material discharging position 21. The manipulator frame 17 moves to the inner end, the clamping and rotating mechanism 13 is released, and the second manipulator 35 places the processed piston at the processing position 22. The first manipulator 34 places the piston to be processed at the processing position 22. The clamping and rotating mechanism 13 clamps the piston to be processed and the clamping and rotating mechanism 13 is driven to rotate by the rotation of the main shaft. The manipulator frame 17 moves vertically to the top of the processing position 22 and exits the processing position 22 to avoid interference. The turning tool assembly 12 cuts the piston in a direction perpendicular to the axis of the lathe 10. At the same time, the manipulator frame 17 moves axially to the outer end of the axial translation mechanism 11 and repeats the previous action. By following the above steps, the device can automatically complete the processing process of the piston.

[0024] See also Figure 2 The tool assembly 12 includes a second slider 23, a second drive 24, a second slide rail 25, and a fixed connection with a tool holder 26. The second slider 23 moves along a longitudinal direction perpendicular to the axial direction on the second slide rail 25 through the second drive 24. In this way, the tool holder 26 is connected and fixed to the second slider 23, and the second drive 24 is a drive motor.

[0025] A first turning tool 27 and a second turning tool 28 are longitudinally arranged below the clamping rotating mechanism 13. These turning tools are fixedly connected to the turning tool holder 26 and can perform cutting tasks. The first turning tool 27 and the second turning tool 28 are used for rough turning and fine turning. The two turning tools can be moved longitudinally perpendicular to the axial direction on the turning tool slide rail through a turning tool mounting seat controlled by a servo motor. The use of rough turning and fine turning can not only extend the service life of the turning tool, but also improve the dimensional accuracy of the workpiece. With the control of the servo motor, the turning tool can move accurately along the preset path, thereby ensuring the accuracy and consistency of the processing.

[0026] Spindle turret 29, push rod 30 and third cylinder 31. The spindle turret 29 of this mechanism is axially rotatably connected to the lathe 10, one end of the push rod 30 is opposite to the spindle turret 29, and is rotatably connected to the sliding frame 36. The third cylinder 31 is installed on the lathe 10, and drives the push rod 30 to move axially on the sliding frame 36. The piston to be processed can be clamped on the spindle turret 29, and positioned and adjusted by the movement of the push rod 30. At the same time, the spindle turret 29 can be rotated on the lathe 10, so as to realize various processing operations of the piston to be processed. The function of the third cylinder 31 is to clamp and release the piston to be processed by driving the movement of the push rod 30.

[0027] See also Figure 3On the spindle head 29, some positioning pins 32 are arranged in the axial direction. At the same time, some positioning holes for receiving the positioning pins 32 are set on the push rod 30. In addition, some insertion holes 33 are also set in the center of the piston, through which the positioning pins 32 can pass. In this way, when the positioning pins 32 are inserted into the positioning holes, the parts can be accurately positioned.
