Description

Technical Field

[0001] The utility model belongs to the field of processing positioning devices, and in particular relates to a processing positioning device suitable for workpieces of various shapes. Background Art

[0002] In mechanical processing production, the corresponding processing positioning device is used to assist the processing of the workpiece in order to reduce labor consumption, reduce safety hazards, and improve production efficiency. However, the processing positioning device commonly used in production has a relatively fixed structure and a relatively simple structure. It can only clamp and position workpieces of a single shape, making the use of the processing positioning device relatively single and unable to cope with the changing work in production.

[0003] Secondly, the processing and positioning device cannot be used for workpieces of various shapes because it can only clamp and position workpieces of a single size. When encountering a workpiece that cannot be positioned, it often requires manpower. This increases the labor intensity during the manual positioning process, and manual fixation has limitations. It is very easy for the workpiece to shift during production and processing, resulting in deviations in the processing of the workpiece and a reduction in the yield rate.

[0004] In addition, manual workpiece fixation during production can easily cause certain production safety hazards, which exposes operators to dangerous working environments, which is disadvantageous to both operators and manufacturers.

[0005] In summary, the processing positioning device that is not applicable to workpieces of various shapes has various problems during use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
