In order to shorten product production cycles, improve production efficiency, and ensure product quality, it is particularly important to carry out refined management and technological innovation for each process in the production process. Among them, the wire cutting process is a key link in the manufacturing process of electronic products, and its processing efficiency and precision directly affect the quality and production efficiency of the final product.

[0003] The installation of angled parts is an important step in the online cutting process. The traditional method of installing angled parts mainly uses a small magnetic platform to carry angle blocks, or uses a U-shaped fixture to clamp and level the tool surface. However, these methods have obvious disadvantages. First, when using a small magnetic platform and angle blocks for installation, it is necessary to stop the machine to adjust and fix the parts, resulting in long downtime and reducing overall production efficiency. Secondly, this installation method is inefficient, which not only increases the labor intensity of operators, but also is not conducive to achieving automated and efficient production goals. In addition, although the U-shaped fixture clamping and leveling tool surface method can improve the installation efficiency to a certain extent, there are often inaccuracies in the installation of small angles on the tool surface, which will affect the cutting accuracy of the parts and thus affect the quality of the product.

[0004] Therefore, a new type of special fixture is developed to solve the problem of angle setting of parts in the wire cutting process, improve setting efficiency, shorten downtime, and ensure setting accuracy. Utility Model Content
