Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a tooling fixture for easy disassembly during automotive parts production. Background Technology

[0002] With the rapid development of the global automotive industry, the production of auto parts is moving towards higher precision, higher efficiency, and greater intelligence. Consumers' demands for the safety, comfort, and personalization of automobiles are constantly increasing, prompting automakers to continuously optimize production processes and improve the manufacturing quality of parts. In this process, tooling fixtures, as an indispensable key equipment on the auto parts production line, undertake the important tasks of positioning, clamping, and supporting parts. Their performance directly determines the processing accuracy, production efficiency, and manufacturing cost of parts.

[0003] However, existing tooling fixtures that are easy to disassemble generally have a serious drawback: they lack a reliable locking function. In order to make disassembly easier, these fixtures often simplify or even abandon the traditional locking structure. In actual processing, automotive parts are subjected to various external forces such as machine tool vibration and cutting force. In addition, most existing tooling fixtures do not have the function of adjusting the clamping height of the parts, and cannot adapt to automotive parts of different specifications and heights, resulting in poor versatility.

[0004] Therefore, those skilled in the art have provided a tooling fixture for easy disassembly in the production of automotive parts to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of traditional easily disassembled tooling fixtures, such as the lack of locking functionality and inconvenient part height adjustment, this utility model provides an easily disassembled tooling fixture for automotive parts production, employing the following technical solution:

[0006] A tooling fixture for easy disassembly in automotive parts production includes a worktable. A clamping mechanism is movably connected to the inner cavity of the worktable. The clamping mechanism includes a rotating rod. One side of the rotating rod is movably connected to the worktable via a bearing. The other side of the rotating rod passes through the inner cavity of the worktable and extends to one side of the worktable. A gear is fixedly connected to the surface of the rotating rod. A toothed plate meshes with the bottom of the gear. A clamping plate is fixedly connected to the other side of the toothed plate. A slot is formed on the surface of the worktable. One side of the clamping plate is slidably connected to the slot. A ratchet is provided on one side of the gear. The inner side of the ratchet is fixedly connected to the rotating rod. A locking plate is provided on one side of the ratchet. A movable rod is fixedly connected to one side of the locking plate. One side of the movable rod is movably connected to the worktable via a bearing. A magnetic block is provided at the top of the movable rod. The top of the magnetic block is fixedly connected to the worktable.

[0007] Optionally, a limiting groove is provided on one side of the clamping plate, and a placement plate is slidably connected to the inner cavity of the limiting groove. A lead screw is threadedly connected to one side of the placement plate, and the bottom of the lead screw is movably connected to the clamping plate through a bearing.

[0008] Optionally, a slide groove is provided on one side of the worktable, and a baffle is slidably connected to the inner cavity of the slide groove. A threaded rod is threadedly connected to the bottom of the baffle, and the threaded rod is movably connected to the worktable through a bearing.

[0009] Optionally, a rotating handle is provided on one side of the workbench, and one side of the rotating handle is fixedly connected to a rotating rod.

[0010] Optionally, the bottom of the locking plate is provided with a stop block, and the bottom of the stop block is fixedly connected to the worktable.

[0011] Optionally, an indicator arrow is provided on one side of the placement plate, and a scale groove is provided on one side of the clamping plate.

[0012] Optionally, a rubber pad is provided on one side of the scale groove, and one side of the rubber pad is fixedly connected to the clamping plate.

[0013] Optionally, a support rod is fixedly connected to the bottom of the workbench, a damping sleeve is fixedly connected to the inner cavity of the support rod, a shock absorber is slidably connected to the inner side of the damping sleeve, a spring is provided on the surface of the shock absorber, and the top of the spring is fixedly connected to the support rod.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. This utility model uses two toothed plates to mesh with gears, driving the clamping plates on both sides to move synchronously, thus achieving symmetrical clamping of the parts. This design ensures that the parts are subjected to uniform force during clamping, avoiding deformation or damage caused by unilateral force. For thin-walled automotive parts, this clamping mechanism is used for processing. The mechanical engagement between the ratchet and the locking plate prevents the rotating rod from reversing after the clamping plates clamp the parts, ensuring that the parts will not loosen due to external forces during processing. In the strong vibration environment generated by the high-speed operation of the machine tool, compared with the traditional single locking fixture, it greatly reduces the displacement rate of the parts and greatly ensures the processing accuracy.

[0016] 2. This utility model achieves precise lifting and lowering of the placement plate within the limiting groove through the threaded transmission between the lead screw and the placement plate. The operator only needs to rotate the lead screw to quickly adjust the placement plate to the required height. Compared with traditional methods of adding or removing shims or complex mechanical adjustments, the adjustment efficiency is greatly improved. It can easily adapt to automotive parts of different thicknesses and heights, meeting diverse production needs. The limiting groove precisely limits the sliding of the placement plate, preventing lateral displacement of the placement plate during processing. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] Example 1:

[0026] Please refer to Figure 1-5 A tooling fixture for easy disassembly in automotive parts production includes a worktable 1. A clamping mechanism 2 is movably connected to the inner cavity of the worktable 1. The clamping mechanism 2 includes a rotating rod 201. One side of the rotating rod 201 is movably connected to the worktable 1 via a bearing, and the other side of the rotating rod 201 passes through the inner cavity of the worktable 1 and extends to one side of the worktable 1. A gear 202 is fixedly connected to the surface of the rotating rod 201. A toothed plate 203 meshes with the bottom of the gear 202. A clamping plate 204 is fixedly connected to the other side of the toothed plate 203. The surface of the table 1 has a slot 205. One side of the clamping plate 204 is slidably connected to the slot 205. One side of the gear 202 is provided with a ratchet 206. The inner side of the ratchet 206 is fixedly connected to the rotating rod 201. One side of the ratchet 206 is provided with a locking plate 207. One side of the locking plate 207 is fixedly connected with a movable rod 208. One side of the movable rod 208 is movably connected to the worktable 1 through a bearing. The top of the movable rod 208 is provided with a magnetic block 209. The top of the magnetic block 209 is fixedly connected to the worktable 1.

[0027] In this embodiment, there are two toothed plates 203, located at the bottom and top of the gear 202 respectively, and two sets of slots 205, which can limit the range of motion of the clamping plate 204, prevent the toothed plates 203 from colliding with the worktable 1, and reduce the maintenance cost of the device. The other side of the movable rod 208 passes through the inner cavity of the worktable 1 and is fixedly connected to a knob. The knob is located on one side of the handle 9. By rotating the knob, the locking plate 207 is rotated and the locking plate 207 is attracted to the magnetic block 209, which can quickly release the locked state of the ratchet 206 and allow the ratchet 206 to reverse.

[0028] Example 2:

[0029] Reference Figure 1-5 A limiting groove 3 is provided on one side of the clamping plate 204. A placement plate 4 is slidably connected to the inner cavity of the limiting groove 3. A lead screw 5 is threadedly connected to one side of the placement plate 4. The bottom of the lead screw 5 is movably connected to the clamping plate 204 via a bearing. A sliding groove 6 is provided on one side of the worktable 1. A baffle 7 is slidably connected to the inner cavity of the sliding groove 6. A threaded rod 8 is threadedly connected to the bottom of the baffle 7. The threaded rod 8 is movably connected to the worktable 1 via a bearing. A rotating handle 9 is provided on one side of the worktable 1. One side of the rotating handle 9 is fixedly connected to the rotating rod 201. A stop block is provided at the bottom of the locking plate 207. 10. The bottom of the abutment block 10 is fixedly connected to the workbench 1. An indicator arrow 11 is provided on one side of the placement plate 4. A scale groove 12 is opened on one side of the clamping plate 204. A rubber pad 13 is provided on one side of the scale groove 12. One side of the rubber pad 13 is fixedly connected to the clamping plate 204. A support rod 14 is fixedly connected to the bottom of the workbench 1. A damping sleeve 15 is fixedly connected to the inner cavity of the support rod 14. A shock absorber rod 16 is slidably connected to the inner side of the damping sleeve 15. A spring 17 is provided on the surface of the shock absorber rod 16. The top of the spring 17 is fixedly connected to the support rod 14.

[0030] In this embodiment: the setting of the limiting groove 3 can limit the range of motion and operation mode of the placement plate 4; the setting of the slide 6 and the baffle 7 can quickly adjust the position according to the processing requirements to form a flexible protective barrier; the setting of the handle 9 allows the operator to drive the entire clamping mechanism 2 by turning the knob, improving the convenience of the device; the abutment block 10 can limit the range of motion of the locking plate 207 to prevent the locking plate 207 from disengaging from the ratchet 206 due to vibration; the operator can accurately adjust the height of the placement plate 4 by observing the indicator arrow 11 and the scale groove 12; the number of rubber pads 13 is two, which can increase the friction between the clamping plate 204 and the part and improve the stability of the clamping mechanism 2; the setting of the damping sleeve 15 and the spring 17 can effectively attenuate the vibration transmitted to the worktable 1 during the machine tool processing.

[0031] The implementation principle of this utility model is as follows: In use, by rotating the lead screws 5 on both sides, the lead screws 5 drive the placement plate 4 to move along the slide groove 6 to adjust the height of the placement plate 4. After completion, the part is placed on the placement plate 4. Rotating the handle 9 drives the rotating rod 201 to rotate. The rotating rod 201 drives the gear 202 to rotate. The gear 202 drives the toothed plates 203 on both sides to move. The toothed plates 203 drive the top clamping plate 204 to move along the groove 205. The clamping plates 204 on both sides move inward at the same time and clamp the part. When it is necessary to disassemble the parts, rotate the movable rod 208 to make the locking plate 207 disengage from the ratchet 206 and attract the magnetic block 209. Then rotate the handle 9 in the opposite direction to release the part. When the worktable 1 vibrates, the vibration is transmitted to the damping rod 16 through the support rod 14. The spring 17 absorbs the vibration energy by elastic deformation. The damping sleeve 15 consumes the vibration kinetic energy through the friction between the internal damping medium and the damping rod 16.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
