Description

Technical Field

[0001] This utility model relates to the field of rack machining technology, and in particular to a rack machining rotary alignment mechanism. Background Technology

[0002] Grinding is an important process in rack machining to improve the surface quality and precision of the rack. Grinding can remove tool marks, burrs and other defects left on the tooth surface after cutting, making the surface smoother, reducing the coefficient of friction, reducing wear and noise during transmission. At the same time, grinding can remove high points on the tooth surface in a small amount, correct tooth profile errors, improve tooth profile precision, and thus improve the accuracy of the meshing between the rack and gear and the transmission efficiency.

[0003] Currently, when processing and grinding racks, both symmetrical sides need to be ground. After one side is ground, it is usually turned over manually. During this process, the rack needs to be unrestrained before it can be ground again after the rack is turned over manually. This reduces production efficiency. Utility Model Content

[0026] Reference Figure 1-6This utility model discloses a rack machining rotation alignment mechanism, comprising: an operating table 1 and an adjustment assembly 28. A first adjustment box 2 is fixedly connected to the upper surface of the operating table 1. The adjustment assembly 28 includes a first cylinder 3, an adjusting rack 4, a bearing 5, a first rotating shaft 6, a gear 7, and a limiting frame 8. The output end of the first cylinder 3 is fixedly connected to the adjusting rack 4. A support block 13 is fixedly connected to the bottom inner wall of the cavity 29. The upper surface of the support block 13 is fixedly connected to the first cylinder 3. The inner surface of the bearing 5 is fixedly connected to the first rotating shaft 6. The cavity 29 is fixedly connected to the bearing 5 on its right inner wall. The side surface of the first rotating shaft 6 is fixedly connected to the gear 7. The side surface of the gear 7 meshes with the adjusting rack 4. The side surface of the first rotating shaft 6 is rotatably connected to the first adjusting box 2. The left surface of the first rotating shaft 6 is fixedly connected to the limiting frame 8. After one side of the workpiece is polished, the third multi-stage cylinder 26 is activated to move the support table 27 downward. The first multi-stage cylinder 16 is activated to move the fixed frame 17 upward, preventing the limiting frame 8 from rotating and interfering with the fixed frame 17 and the polishing block. When a collision occurs, the first cylinder 3 in the first regulating box 2 and the second regulating box 15 are activated simultaneously. The output end of the first cylinder 3 drives the adjusting rack 4 to move. The adjusting rack 4 meshes with the gear 7. The movement of the adjusting rack 4 drives the gear 7, the first rotating shaft 6, the limiting frame 8, and the workpiece to rotate, which can rotate and flip the workpiece without manual flipping, saving time for manual material handling, rotation and flipping, and loading, thereby improving processing efficiency. The first regulating box 2 has a cavity 29 inside. The top inner wall of the cavity 29 is fixedly connected to the first limiting block 11 and the second limiting block 12. The first limiting block 11 and the second limiting block 12 limit the movement position of the adjusting rack 4, so that the distance driven by the first cylinder 3 to move the adjusting rack 4 is accurate, thereby ensuring that the rotation angle of the first rotating shaft 6 and the limiting frame 8 is constant. This structure can ensure that the rotation angle of the workpiece is accurate every time, which is conducive to improving the subsequent processing accuracy and quality stability of the rack and reducing the scrap rate.

[0027] A second cylinder 14 is fixedly connected to the upper surface of the operating table 1. A second regulating box 15 is fixedly connected to the output end of the second cylinder 14. The lower surface of the second regulating box 15 is slidably connected to the operating table 1.

An electric telescopic rod 9 is fixedly connected to the inner surface of the limiting frame 8. A limiting plate 10 is fixedly connected to the end of the electric telescopic rod 9 away from the limiting frame 8.

The inner surface of the first groove 18 is slidably connected to the slider 20. When the second multi-stage cylinder 19 is activated, the output end of the second multi-stage cylinder 19 extends and drives the grinding block 24 to move, so that different positions of the limited workpiece can be processed and ground.

[0029] A fixed box 21 is fixedly connected to the lower surface of the slider 20. A motor 22 is fixedly connected to the bottom inner wall of the fixed box 21. A second rotating shaft 23 is fixedly connected to the output end of the motor 22. The side surface of the second rotating shaft 23 is rotatably connected to the fixed box 21. A grinding block 24 is fixedly connected to the lower surface of the second rotating shaft 23. When the motor 22 is started, the output end of the motor 22 drives the second rotating shaft 23 and the grinding block 24 to rotate. The first multi-stage cylinder 16 is started to drive the fixed frame 17 to move down. The grinding block 24 grinds the surface of the workpiece that is in the limit position.

[0030] The operating table 1 has a second groove 25 inside. The bottom inner wall of the second groove 25 is fixedly connected to a third multi-stage cylinder 26. The output end of the third multi-stage cylinder 26 is fixedly connected to a support platform 27. Before processing and grinding, the third multi-stage cylinder 26 is started to move the support platform 27 upward. A limit block is set on one side of the first adjustment box 2 to limit the movement of the support platform 27. When the workpiece is being ground, the support platform 27 can support the bottom of the workpiece. When the workpiece needs to be rotated and flipped, the third multi-stage cylinder 26 is started to move the support platform 27 downward to avoid the limit frame 8 from colliding with the support platform 27. In this application, the first cylinder 3, the electric telescopic rod 9, the second cylinder 14, the first multi-stage cylinder 16, the second multi-stage cylinder 19, the motor 22, and the third multi-stage cylinder 26 are all electrically connected to the controller.

The second cylinder 14 is activated to move the second adjusting box 15, which can limit the left and right ends of the workpiece. The electric telescopic rod 9 is activated to move the limiting plate 10, which limits the front and rear ends of the workpiece. The motor 22 is activated, and the output end of the motor 22 drives the second rotating shaft 23 and the grinding block 24 to rotate. The first multi-stage cylinder 16 is activated to move the fixed frame 17 downward, and the grinding block 24 grinds the surface of the workpiece. The second multi-stage cylinder 19 is activated, and the output end of the second multi-stage cylinder 19 extends to move the grinding block 24, which can grind different positions of the workpiece. After one side of the workpiece is ground, the third multi-stage cylinder 26 is activated to move the support platform 27 downward, and the first multi-stage cylinder 16 is activated to move the fixed frame 17 upward. The first cylinder 3 is started synchronously, and the output end of the first cylinder 3 drives the adjusting rack 4 to move. The adjusting rack 4 meshes with the gear 7. The movement of the adjusting rack 4 drives the gear 7, the first rotating shaft 6, the limiting frame 8 and the workpiece to rotate, which can rotate and flip the workpiece. The first limiting block 11 and the second limiting block 12 are set to limit the movement position of the adjusting rack 4, so that the movement position of the adjusting rack 4 is fixed, thereby ensuring that the rotation angle of the first rotating shaft 6, the limiting frame 8 and the workpiece is fixed. This structure can easily rotate the rack workpiece without manual rotation and flipping, saving the time of rotating and flipping the workpiece, thereby improving the processing efficiency. Furthermore, by setting the first limiting block 11 and the second limiting block 12, it can be ensured that the rotation angle of the workpiece is accurate each time, which is conducive to improving the overall processing accuracy and quality stability of the rack and reducing the scrap rate.
