AI Technical Summary

Technical Problem

Existing watch crystal pressing devices often result in inaccurate alignment between the crystal and the case during pressing, leading to misalignment or tilting. This affects the watch's appearance and sealing performance. Furthermore, uneven pressure during manual pressing can easily cause the crystal to crack or the case to be damaged.

Method used

A pressing device comprising a clamping plate, a pushing block, a rotating rod, and an elastic element was designed. The clamping plate is moved synchronously by the rotating rod to achieve precise alignment, and the pressure is evenly distributed by the elastic element and the support column to avoid excessive local stress.

Benefits of technology

It achieves precise alignment between the watch crystal and the watch case, reducing the breakage rate of the watch crystal and scratches on the watch case, and improving the watch's sealing and aesthetics.

Abstract

The utility model relates to the field of watch manufacturing and maintenance, in particular to a watch glass watch mirror pressing device which comprises an operation table, a punching machine is installed on the operation table, a sliding groove is formed in the operation table, a handle is arranged on the left side of the punching machine, a clamping plate a is connected to the operation table in a sliding mode, the clamping plate a slides on the sliding groove, and a fixing rod is connected to the operation table in a sliding mode. A pushing block is slidably connected to the operation table, the left end of the fixing rod is fixedly connected to the clamping plate a, the right end of the fixing rod is fixedly connected to the pushing block, and the fixing rod is sleeved with four elastic pieces a. The rotating rod is rotated, the sliding block is driven to press downwards, the pushing block and the clamping plate b are promoted to act, the clamping plate a and the clamping plate b synchronously move towards the middle, the watch case and the watch mirror are clamped, in the process, the situation that the watch mirror is damaged due to too large clamping force can be avoided, it is ensured that the watch mirror is completely aligned with an opening of the watch case, and accurate alignment is achieved.
