Description

Technical Field

[0001] This utility model relates to a retaining ring tooling, and more particularly to a tooling for cutting openings for retaining rings of different diameters. 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 an opening cutting fixture for snap rings of different diameters, so as to facilitate the simultaneous assembly of snap rings of different sizes using the same fixture, and to use a laser to cut snap rings of different sizes without changing the fixture.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A cutting fixture for opening circlips of different diameters includes a fixture body, the fixture body including a fixture base and a lever, the fixture base having at least two circlip placement slots of different diameters on its left and right sides respectively, the lever being separately disposed from the fixture base and used to pull the circlips out of the circlip placement slots.

[0006] Furthermore, the size of the opening on the retaining ring placement slot matches the cutting size required for retaining rings of different diameters.

[0007] Furthermore, the upper and lower end faces of the retaining ring placement groove penetrate the upper and lower end faces of the tooling base.

[0008] Furthermore, the retaining ring placement slots on the left side and the right side of the tooling base are staggered.

[0009] Furthermore, the lever includes a handle, a connecting rod, and a paddle, with the handle at the upper end of the connecting rod and the paddle at the lower end.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The tooling base of this utility model is provided with open-type retaining ring placement slots of different sizes, which can simultaneously place several retaining rings of different sizes on the same tooling base, so that the retaining rings of different sizes can be cut with laser without changing the tooling, saving time and effort and improving production efficiency.

[0012] 2. This utility model is equipped with a lever, which is separately set from the tooling base. It can pull the snap ring out of the snap ring placement slot without damaging the snap ring, thereby speeding up the production process and improving production efficiency.

[0013] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0021] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0024] Example: Figure 1-5 As shown,

[0025] A cutting fixture for snap rings of different diameters includes a fixture body, which includes a fixture base 1. The left and right sides of the fixture base 1 are each provided with two snap ring placement slots 2 with different diameters for storing snap rings 4 of different diameters. The size of each snap ring placement slot 2 is matched with the corresponding size of the snap ring 4. After the corresponding snap ring 4 is placed into the snap ring placement slot 2, the snap ring 4 will not wobble in the snap ring placement slot 2, but the snap ring 4 can slide up and down in the snap ring placement slot 2.

[0026] The size of the opening on the circlip placement groove 2 matches the cutting size required for circlips 4 of different diameters. In this way, when using laser cutting, the laser can cut the circlip 4 simply by passing through the opening on the circlip placement groove 2.

[0027] This allows for the cutting of retaining rings of different diameters without needing to replace the tooling base 1, saving time and effort while improving production efficiency.

[0028] The retaining ring placement slots 2 on the left side and 2 on the right side of the tooling base 1 are staggered, which can make full use of the space on the tooling base 1, so as to produce a tooling base 1 with good quality and high efficiency.

[0029] The lever 3 is set separately from the tooling base 1 and is used to pull the snap ring 4 out of the snap ring placement slot 2. The lever 3 includes a handle 3-1, a connecting rod 3-2 and a paddle 3-3. The upper end of the connecting rod 3-2 is provided with a handle 3-1 and the lower end is provided with a paddle 3-3. The paddle 3-3 is a curved paddle 3-3 to avoid damaging the snap ring 4.

[0030] During operation, the fixture base 1 is fixed at a predetermined position on the laser cutting table using a clamp. Then, the retaining ring 4 to be cut is placed into the corresponding retaining ring placement slot 2. The retaining ring 4 is cut by laser at the opening. After cutting, the cut retaining ring 5 is pulled out of the retaining ring placement slot 2 using a lever 3. Then, two flat-nose pliers are used to flatten the opening of the cut retaining ring 5 so that the retaining ring is on the same horizontal plane. The two cut surfaces are set parallel to each other on both sides of the radial axis of the cut retaining ring 5.

[0031] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
