Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a box metal parts processing fixture. Background Art

[0002] The rotary box is a box structure that can rotate around a horizontal axis. The strength, stability, and precision of its overall structure will directly affect its working stability and accuracy, and thus have certain requirements for its processing quality. During the processing, the stability and efficiency of clamping are one of the important factors affecting the processing quality and efficiency.
