Description

Technical Field

[0001] This patent relates to the technical field of gear processing, and specifically relates to a fixing tooling for gear processing. Background Art

[0002] A gear refers to a mechanical element with teeth on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. Mechanical gears are important components of the transmission mechanism, and the transmission of the entire transmission mechanism is achieved through the transmission between mechanical gears. When machining mechanical gears, operations such as opening and grinding are required.

[0003] The existing gear fixing fixture consists of two groups of clamping plates. By turning the screws that control the clamping plates of the two groups, the two clamping plates are clamped on the gear. However, this kind of gear fixing is not convenient for changing the grinding angle of the gear. Workers need to frequently change the grinding position or frequently disassemble and assemble the gear for grinding, resulting in poor practicability. Therefore, we propose a fixing tooling for gear processing. Summary of the Utility Model

[0018] The technical solutions in the embodiments of this patent will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this patent without creative efforts shall fall within the protection scope of this patent.

[0019] Please refer toFigure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a fixing tooling for gear processing, including a base 1. A fixing plate 2 is fixedly installed at the top of the base 1. A cross column 3 is fixedly installed at the top of the front side of the fixing plate 2. A vertical plate 4 is fixedly installed at the left side of the top of the base 1. A cross plate 5 is fixedly installed at the top of the right side of the vertical plate 4. A chute is provided at the bottom of the cross plate 5. A lead screw motor 6 is fixedly installed at the top of the left side of the vertical plate 4. A lead screw 7 is fixedly installed at the right end of the rotating shaft of the lead screw motor 6. A nut 8 is screwed on the side wall of the lead screw 7. A slider 9 is fixedly installed at the top of the nut 8. The top of the slider 9 is slidably installed in the chute. A connecting rod 10 is fixedly installed at the bottom of the nut 8. A toothed plate 11 is fixedly installed at the bottom of the connecting rod 10;

[0020] As Figure 1 shown, the gear to be polished can be sleeved on the side wall of the cross column 3, and then the position of the toothed plate 11 is moved so that the bottom of the toothed plate 11 meshes with the top of the gear.

[0021] The cross column 3 includes a column body 12 and a bearing 16. The rear end of the column body 12 is fixedly installed at the top of the front side of the fixing plate 2. A threaded groove 13 is provided at the front end of the column body 12. A bolt 14 is screwed in the threaded groove 13. A round table ring 15 is fixedly installed on the side wall of the bolt 14. The inner side wall of the inner ring of the bearing 16 is fixedly installed on the outer side wall of the column body 12. Slots 17 are provided at both upper and lower ends of the outer side wall of the outer ring of the bearing 16. A sliding rod 18 is slidably installed in the slot 17. A pressing plate 19 is fixedly installed at the outer end of the sliding rod 18. One end of a vertical rod 20 is fixedly installed on the inner side surface of the pressing plate 19. The other end of the vertical rod 20 abuts against the outer side wall of the round table ring 15.

[0022] As Figure 3 shown, by rotating the bolt 14, the bolt 14 drives the round table ring 15 to move leftward, and the side wall of the round table ring 15 drives the two vertical rods 20 to move away from each other, so as to press and support the upper and lower ends of the inner side wall of the gear through the two pressing plates 19.

[0023] Specifically, the slot 17 is a square groove, the sliding rod 18 is in the shape of a square rod matching the slot 17, and the side wall of the sliding rod 18 is relatively slidably attached to the inner side wall of the slot 17.

[0024] By setting both the slot 17 and the sliding rod 18 as squares, the sliding rod 18 can be prevented from rotating in the slot 17, thereby changing the orientation of the pressing plate 19.

[0025] Specifically, a spring 21 is sleeved on the side wall of the sliding rod 18. One end of the spring 21 is fixedly installed on the inner side surface of the pressing plate 19, and the other end of the spring 21 is fixedly installed on the outer side wall of the outer ring of the bearing 16.

[0026] Specifically, a rubber pad 22 is fixedly installed on the outer side surface of the pressing plate 19.

[0027] The rubber pad 22 is used to increase the pressing friction effect of the pressing plate 19 on the inner side wall of the gear.

[0028] Specifically, one end of the vertical rod 20 that fits against the outer side wall of the frustum ring 15 is provided with a spherical surface 23, and the spherical surface 23 fits against the outer side wall of the frustum ring 15.

[0029] The setting of the spherical surface 23 can increase the sliding effect between the end of the vertical rod 20 and the side wall of the frustum ring 15.

[0030] Specifically, a through hole 24 is provided on the upright plate 4, and the through hole 24 is located on the left side of the toothed plate 11.

[0031] Working principle: As Figure 3 shown, by rotating the bolt 14, the bolt 14 can drive the frustum ring 15 to move leftward, and through the side wall of the frustum ring 15, the two vertical rods 20 are driven to move away from each other. Then, the two pressing plates 19 are used to press and support the upper and lower ends of the inner side wall of the gear. As Figure 1 shown, the gear to be polished can be sleeved on the side wall of the cross column 3, and then the lead screw motor 6 drives the nut 8 to move leftward to engage the bottom of the toothed plate 11 with the top of the gear by moving the position of the toothed plate 11. At this time, the staff can polish the open edge teeth of the gear, or the toothed plate 11 can be moved leftward to drive the gear to rotate and change the polishing position.
