Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a locking jig for ring processing. Background Technique

[0002] The ring die-making process is an important process in ring processing jigs and also a time-consuming process in ring processing jigs. It is a process of trimming and repairing the rough ring blank to make it have a beautiful shape and a flat surface. Each ring blank cast by lost wax casting needs to be manually trimmed and polished one by one by die-making workers. Only after die-making can the ring be processed by ring inlaying, polishing, electroplating, etc. If problems such as filing marks, uneven surface, and asymmetrical ornaments occur during the die-making process, it will directly affect the beauty of the product and also affect subsequent processes such as stone inlaying, polishing, and electroplating. The die-making process generally includes several process flows such as trimming, filing, repairing, and polishing.

[0003] Most rings are of a ring structure. During the processing process, they need to be fixed and positioned by a jig before processing. However, in the prior art, during the processing of rings, either manual clamping is used or the structure of the jig used is relatively complex, resulting in cumbersome operation procedures, limited positioning accuracy, and inconvenient clamping and taking of ornaments during the processing process. Content of the Utility Model

[0004] The purpose of the utility model is to provide a locking jig for ring processing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A locking jig for ring processing, including a base, an expansion part is fixedly installed on the top of the base, and a copper sleeve is sleeved outside the expansion part, and a taper screw is threadedly installed on the top of the expansion part.

[0006] Preferably, a ring is sleeved outside the copper sleeve.

[0007] Preferably, a plurality of cuts are opened at the tops of the expansion part and the copper sleeve.

[0008] Preferably, internal threads are provided inside the expansion part.

[0009] Preferably, a first pin hole is opened at the bottom of the copper sleeve, a second pin hole is opened at the bottom of the expansion part, and the same positioning pin is installed on the first pin hole and the second pin hole.

[0010] Preferably, a plurality of mounting holes are opened around the bottom of the base.

[0011] Preferably, a boss structure is provided at the middle position of the copper sleeve.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When in use, the ring is sleeved on the copper sleeve, and then the inclined screw is tightened. The inclined screw 5 squeezes the expansion part, and the expansion part squeezes the copper sleeve, so that the copper sleeve can clamp the ring tightly;

[0014] The utility model has a simple structure and is convenient to use. It is convenient to firmly clamp the ring and facilitate the processing operation of the ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 , the present utility model provides a technical solution: a locking fixture for ring processing, including a base 1, on the top of the base 1, an expansion part 2 is fixedly installed, and a copper sleeve 3 is sleeved outside the expansion part 2, and an inclined screw 5 is threadedly installed on the top of the expansion part 2.

[0019] In the present utility model, a ring 4 is sleeved outside the copper sleeve 3.

[0020] In the present utility model, a plurality of cuts are provided on the tops of the expansion part 2 and the copper sleeve 3, which is convenient for the deformation of the expansion part 2 and the copper sleeve 3.

[0021] In the present utility model, internal threads are provided inside the expansion part 2, which is convenient for the use of the inclined screw 5.

[0022] In the present utility model, a pin hole one 6 is provided at the bottom of the copper sleeve 3, a pin hole two 7 is provided at the bottom of the expansion part 2, and the same positioning pin 8 is installed on the pin hole one 6 and the pin hole two 7, which is convenient for the stable connection between the copper sleeve 3 and the expansion part 2.

[0023] In the present utility model, a plurality of mounting holes 9 are provided around the bottom of the base 1, which is convenient for the installation and fixation of the fixture.

[0024] In the present utility model, a boss structure is provided at the middle position of the copper sleeve 3, facilitating the placement of the ring 4.

[0025] Working principle of the present utility model: During use, the ring 4 is sleeved on the copper sleeve 3, and then the tapered screw 5 is tightened. The tapered screw 5 presses against the expansion part 2, and the expansion part 2 presses against the copper sleeve 3, enabling the copper sleeve 3 to clamp the ring.
