Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a multi-directional clamping device for processing rocket parts. Background Art

[0002] Rocket parts processing is a complex process involving multiple steps and technical fields. Rockets are composed of multiple key components, each of which needs to be precisely designed and manufactured to ensure the performance and safety of the rocket. In the processing of rocket parts, multi-directional clamping devices are required to firmly clamp and fix the rocket parts in order to ensure the processing accuracy and efficiency of the parts.

[0003] The existing multi-directional clamping device for processing rocket parts places the rocket parts to be processed on the clamping table, and then controls the operation of clamping modules set at different positions, so that the motor drives the clamp to approach the rocket parts, and then clamps and fixes them from multiple directions. However, in actual use, due to the different appearance specifications of different parts to be processed, when clamping and fixing some relatively special-shaped parts, the positions of the clamping modules set at some positions cannot be freely adjusted, which may cause the clamping modules to fail to effectively play the clamping and fixing effect, resulting in a decrease in the fixing effect of the parts. During the processing, the parts may be offset to a certain extent due to vibration, thereby affecting the processing accuracy of the parts and affecting the processing effect of the parts. In subsequent inspections, these parts with poor precision need to be sent back for reprocessing, reducing the processing efficiency of rocket parts. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies of the prior art and provides a multi-directional clamping device for rocket parts processing, which can freely adjust the positions of different clamping claws when clamping and fixing rocket parts. By adjusting the positions of different clamping claws, these clamping claws can clamp and fix the parts from multiple directions at the optimal position, which can effectively ensure the clamping effect of parts with different appearance specifications.
