Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures for watch processing, in particular to a sandblasting fixture for watch cases. Background Art

[0002] During the production process of watches, the watch cases need to be sandblasted. In traditional sandblasting, a sandblasting plate is often used to load multiple watch cases simultaneously, and then the sandblasting plate is sent into a sandblaster for sandblasting. The sandblasting plate is provided with a plurality of fixing columns corresponding to the watch cases. During installation, after fixing the watch case on the fixing column, a cover plate is installed to fix the watch case. After a single sandblasting of the watch case, due to the orientation of the product, the lower surface of the watch case cannot be completely sandblasted. Therefore, during the processing, the watch case needs to be reinstalled after being flipped for secondary sandblasting. However, since the watch case is installed corresponding to the fixing columns on the sandblasting plate one by one, when the watch case is subjected to secondary sandblasting, it needs to be removed and flipped one by one and then reinstalled, which makes the processing time-consuming and laborious and greatly affects the production efficiency.

[0003] In addition, before sandblasting, it is necessary to use a shielding object to shield the areas of the watch case that do not need to be sandblasted, and the operation is very troublesome. Summary of the Utility Model

[0008] A fixed stop block, which is arranged at the other end of the bearing part;

[0009] A series connection assembly, which is sleeved on the bearing part. One end of the series connection assembly abuts against the fixed stop block. The series connection assembly includes a plurality of protective blocks that abut against each other, and a positioning groove for positioning the watch case to be sandblasted is formed at the boundary between two adjacent protective blocks;
