Description

Technical Field

[0001] This utility model relates to the technical field of automotive assembly tooling, specifically to an auxiliary tooling for an anti-rotation device. Background Technology

[0002] Currently, when assembling drive motor brackets and rear axles on automobiles, employees need to hold down the nut end by hand when tightening bolts. Due to space constraints, open-end wrenches are difficult to use, and tightening machines do not have built-in anti-rotation mechanisms to prevent bolts from rotating during tightening. This operation requires employees to hold the tightening machine with one hand and hold down the anti-rotation mechanism with the other, which poses a safety hazard. At the same time, it also causes significant hand fatigue when operating at high speeds. Summary of the Invention

[0003] To address the existing technology's shortcomings in assembling drive motor brackets and rear axles on automobiles, where employees must manually press down the nut end when tightening bolts due to space constraints, the inconvenience of using open-end wrenches, and the lack of built-in anti-rotation mechanisms on tightening machines to prevent bolts from rotating during tightening, this operation requires employees to hold the tightening machine in one hand and press down on the anti-rotation mechanism with the other, posing safety hazards. Furthermore, it suffers from significant hand fatigue during high-frequency operation. Therefore, this invention provides an auxiliary tooling for an anti-rotation device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses an auxiliary tooling for an anti-rotation device, including a limiting nylon block. The limiting nylon block has a limiting hole for limiting the nut, and the top of the limiting nylon block has a flat part for abutting and limiting the workpiece. The limiting nylon block also has a handle.

[0006] As a preferred embodiment of this utility model, the limiting hole is a regular dodecagonal hole.

[0007] As a preferred embodiment of this utility model, the handle and the limiting nylon block are inclined together.

[0008] As a preferred embodiment of this utility model, the handle is welded to the limiting nylon block.

[0009] As a preferred embodiment of this utility model, the end of the handle is provided with a curved grip.

[0010] As a preferred embodiment of this utility model, the limiting hole is provided as a through-hole limiting nylon block and is sleeved on the outside of the nut.

[0011] As a preferred embodiment of this utility model, the surface of the flattened part is provided with a rubber layer.

[0012] As a preferred embodiment of this utility model, the handle or grip is provided with a rubber sleeve.

[0013] The beneficial effects of this utility model are:

[0014] This anti-rotation device uses a dodecagonal hole to engage the nut end, and a flat part on a limiting nylon block to hold the bracket in place for anti-rotation. A handle is included; after pre-tightening the bolts and nuts, the worker places the device on the corresponding nut end requiring anti-rotation, starts the tightening machine, and then removes the anti-rotation device using the handle. Furthermore, this invention features a simple structure, convenient operation, and effectively solves space constraints and ergonomic problems during drive motor bracket and post-assembly. It also significantly improves production efficiency and ergonomics. The auxiliary tooling for this anti-rotation device is easy to manufacture, has low manufacturing cost, and low replacement cost.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example 1: As Figure 1As shown, this utility model discloses an auxiliary tooling for an anti-rotation device, including a limiting nylon block 1. The limiting nylon block 1 has a limiting hole 2 for limiting the nut, and a flat part 3 on the top of the limiting nylon block 1 for abutting and limiting the workpiece. The limiting nylon block 1 also has a handle 4. A dodecagonal hole is used to engage the nut end, and the flat part 3 on the limiting nylon block 1 abuts against the bracket to prevent rotation. The handle allows the worker to pre-tighten the bolt and nut, place the device on the corresponding nut end requiring anti-rotation, start the tightening machine to tighten, and then remove the anti-rotation device using the handle. Furthermore, this utility model has the advantages of simple structure, convenient operation, effective solution to space constraints and ergonomic problems during drive motor bracket and post-assembly, and significant improvement in production efficiency and ergonomics. The auxiliary tooling for the anti-rotation device of this utility model is easy to manufacture, has low manufacturing cost, and low replacement cost.

[0021] The limiting hole 2 is a regular dodecagonal hole, which facilitates docking with the nut end and has a good effect in preventing the nut from rotating.

[0022] The handle 4 and the limiting nylon block 1 are inclined together, so that the handle 4 and the limiting nylon block 1 can be set at different angles according to different needs, thereby facilitating operation.

[0023] The handle 4 is welded to the limiting nylon block 1, which is easy to manufacture.

[0024] The limiting nylon block 1 is made of high-strength metal material, which has the characteristics of high strength and is not easily damaged.

[0025] Example 2, as follows Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the end of the handle 4 is provided with a curved grip 5, which makes it easier for the operator to hold.

[0026] The limiting hole 2 is set through the limiting nylon block 1 and is sleeved on the outside of the nut; the surface of the flattening part 3 is provided with a rubber layer to prevent the flattening part 3 from directly contacting the workpiece and causing wear to the workpiece; the handle 4 or grip 5 is provided with a rubber sleeve to prevent wear. During assembly, the employee can directly use this anti-rotation auxiliary tooling to clamp and tighten it. During the process, this anti-rotation auxiliary tooling does not need to be held by hand. The employee can directly use both hands to tighten the bolts with the tightening machine.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
