Description

Technical Field

[0001] The utility model belongs to the technical field of watch processing jigs, in particular to a watch cover clamping jig. Background Art

[0002] In the field of watch manufacturing, the appearance quality of watches has always been one of the important indicators to measure the quality of products. As an important part of a watch, the processing accuracy and surface quality of the watch cover directly affect the overall appearance and user experience of the watch. Therefore, the processing technology and tools for the watch cover are extremely strict.

[0003] In the traditional processing of watch covers, the internal support structure clamping solution is usually used for fixing and positioning. However, this solution has exposed some problems in practical applications. First, during the clamping process of the internal support structure clamping, due to uneven force or excessive clamping force, it is easy to cause scratches, crushing or deformation on the surface of the watch cover, which is the so-called "three injuries" phenomenon. This not only affects the appearance quality of the watch cover, but also may pose a potential threat to the sealing and functional performance of the watch cover.

[0004] Secondly, the traditional internal support structure clamping solution is unreliable in terms of positioning. Due to the complex structural design of the fixture, positioning deviation is prone to occur during the clamping process, resulting in the inability to guarantee processing accuracy. This not only increases the difficulty and cost of subsequent processing, but may also affect the overall quality of the watch.

[0005] In addition, the traditional fixture design is relatively complex, which is not conducive to the production of batch fixtures. In the process of mass production of watches, the complex fixture design not only increases the manufacturing cost, but also reduces the production efficiency. Therefore, the development of a fixture with simple structure, reliable positioning and easy batch production has become an urgent need in the industry. Utility Model Content
