Abstract
Description
Technical Field
[0001] This utility model relates to a circlip cutting fixture, and more particularly to a circlip opening cutting fixture. Background Technology
[0002] When manufacturing open-type retaining rings, it is necessary to first produce regular closed-type retaining rings, and then use a laser to make laser cuts on the closed-type retaining rings. However, because customer needs are different, the required opening size is also different, and the retaining rings also need tooling for support so that they can be laser cut. If a different tooling is used for each size, it is time-consuming, labor-intensive, and has low production efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a circlip opening cutting fixture that can fix circlips of different diameters without changing the fixture. Only the circlip of the required size needs to be replaced, and the fixed circlip can be cut with a laser.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0005] A retaining ring opening cutting fixture includes a fixture base. The fixture base has a retaining ring placement groove and a fixing groove. The fixing groove is located on the left side of the retaining ring placement groove and communicates with the fixing groove. The side of the retaining ring placement groove opposite to the fixing groove communicates with the corresponding side of the fixture base to form an open retaining ring placement groove. A fixing block is provided in the fixing groove. At least two bolt holes are provided on the side of the fixture base located on the left side of the fixing groove. Each bolt hole communicates with the corresponding fixing groove and a fastening bolt is provided in each bolt hole.
[0006] Furthermore, the upper and lower surfaces of the retaining spring placement groove and the fixing groove both penetrate the upper and lower surfaces of the corresponding tooling base, facilitating the entry and exit of the retaining spring and the fixing block.
[0007] The fixing groove includes a limiting groove and a connecting groove. The connecting groove is located at the middle right side of the limiting groove, forming a T-shaped fixing groove with the limiting groove. The left side of the limiting groove communicates with the corresponding bolt hole, so that the fastening bolt in the bolt hole can tighten the fixing block. The right side communicates with the connecting groove for placing the fixing block. The connecting groove communicates with the snap ring placement groove, so that the fixing block can fix the snap ring in the snap ring placement groove.
[0008] Furthermore, the fixing block includes a limiting block and a connecting block, wherein the connecting block is disposed at the middle right side of the limiting block, forming a T-shape with the limiting block.
[0009] Furthermore, the limiting block is disposed within the limiting groove, and the length of the limiting block matches the length of the limiting groove. The width of the limiting block is less than the width of the limiting groove. When the limiting block is located on the left side within the limiting groove, the end of the connecting block away from the limiting block is located on the right side of the connecting groove.
[0010] Furthermore, the fixing block can slide within the fixing groove.
[0011] Furthermore, the size range of the retaining spring placed in the retaining spring placement groove is: the diameter is not greater than the diameter of the retaining spring placement groove and not less than the opening diameter of the retaining spring placement groove. This facilitates the fixing block to fix it in the retaining spring placement groove. When fixing, the retaining spring is placed in the retaining spring placement groove. Rotating the fastening bolt causes the fastening bolt to push the limiting block and drive the connecting block to move in the direction of the retaining spring until the connecting block contacts the retaining spring and the retaining spring can no longer move in the retaining spring placement groove. At this time, the retaining spring is fixed.
[0012] To loosen the retaining ring, simply rotate the fastening bolt in the opposite direction to separate it from the fixing block. At this point, whether manually or by tilting the tooling base, the fixing block can slide within the fixing groove, releasing it from its grip on the retaining ring.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The tooling base of this utility model is provided with a retaining ring placement groove and a fixing groove with a fixing block. A retaining ring with a diameter not greater than the diameter of the retaining ring placement groove and not less than the opening diameter of the retaining ring placement groove is placed in the retaining ring placement groove. The retaining rings within the above range can be fixed without changing the tooling. Then, laser cutting is performed. It has a wide range of applications, can speed up the production process and improve production efficiency.
[0015] 2. In this utility model, a fixing block is used to fix the circlip in the slot, which facilitates laser cutting, improves cutting quality, and enhances product quality.

[0027] Example: Figure 1-5 As shown,
[0028] A circlip opening cutting fixture includes a fixture base 1, on which a circlip placement groove 2 and a fixing groove 3 are provided. The upper and lower surfaces of the circlip placement groove 2 and the fixing groove 3 are both through the upper and lower surfaces of the corresponding fixture base 1.
[0029] The fixing groove 3 is located on the left side of the retaining spring placement groove 2, and the retaining spring placement groove 2 is connected to the fixing groove 3. The side of the retaining spring placement groove 2 opposite to the fixing groove 3 is connected to the side of the corresponding tooling base 1, forming an open retaining spring placement groove 2. A fixing block 4 is provided in the fixing groove 3, and the fixing block 4 can slide in the fixing groove 3.
[0030] The tooling base 1 has two bolt holes on its side located to the left of the fixing groove 3. Each bolt hole is connected to the corresponding fixing groove 3, and each bolt hole is equipped with a fastening bolt 5.
[0031] The fixing groove 3 includes a limiting groove 3-1 and a connecting groove 3-2. The connecting groove 3-2 is located at the middle right side of the limiting groove 3-1, forming a T-shaped fixing groove 3 with the limiting groove 3-1. The left side of the limiting groove 3-1 is connected to the corresponding bolt hole, and the right side is connected to the connecting groove 3-2. The connecting groove 3-2 is connected to the snap ring placement groove 2.
[0032] The fixing block 4 includes a limiting block 4-1 and a connecting block 4-2. The connecting block 4-2 is located at the middle right side of the limiting block 4-1, forming a T-shaped fixing block 4 with the limiting block 4-1.
[0033] The limiting block 4-1 is set inside the limiting groove 3-1, and the length of the limiting block 4-1 matches the length of the limiting groove 3-1. The width of the limiting block 4-1 is less than the width of the limiting groove 3-1. When the limiting block 4-1 is located on the left side inside the limiting groove 3-1, the end of the connecting block 4-2 away from the limiting block 4-1 is located on the right side of the connecting groove 3-2.
[0034] When using it, place the corresponding snap ring in the snap ring placement slot 2. Use the fastening bolt 5 to push the limiting block 4-1 to drive the connecting block 4-2 towards the snap ring until the connecting block 4-2 contacts the snap ring and the snap ring can no longer move in the snap ring placement slot 2. At this time, the snap ring is fixed. Use a laser to cut the snap ring through the opening on the snap ring placement slot 2. After cutting, rotate the fastening bolt 5 in the opposite direction so that the fixing block 4 can slide in the fixing slot 3, releasing the fixing block 4 from the snap ring. Take the cut snap ring out of the snap ring placement slot 2 using the lever. Then use two flat-nose pliers to flatten the opening of the cut snap ring 6 so that the cut snap ring 6 is on the same horizontal plane. The two cut planes are set parallel to each other on both sides of the radial axis of the cut snap ring 6.
