Description

Technical Field

[0001] The utility model relates to the technical field of aluminum fixtures, in particular to a universal fixture for processing aluminum parts. Background Art

[0002] With the continuous development of the metallurgical industry, aluminum profiles have become common in our daily lives. Aluminum profiles can be easily formed through various processes. Mechanical accessories made of aluminum profiles have high strength, good plasticity, excellent conductivity and corrosion resistance. In the process of processing aluminum mechanical accessories, they need to be cut and polished. During cutting and polishing, they need to be fixed, which requires the use of a clamp. However, the existing clamp is not convenient for clamping and fixing the aluminum parts on all four sides, making the fixation of the aluminum parts not stable enough, and cannot effectively limit the movement and rotation of the aluminum parts in all directions, reducing the stability of the clamping, and it is not convenient to clamp and fix aluminum parts of different specifications, reducing the flexibility of the device; therefore, we propose a universal aluminum processing clamp to solve this problem.
