Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to an adjustable clamp for automobile parts processing. Background Art

[0002] Auto parts processing refers to various processing and manufacturing processes for auto parts to produce parts that meet design requirements and standards. These parts can include engine parts, chassis parts, body parts, etc. Auto parts generally need to be clamped before using processing equipment so that they can be stably installed on the processing table, thereby ensuring the stability of the processing.

[0003] When grinding the end and outer wall of the transmission shaft, it is generally necessary to use a clamping device to clamp it first. The current clamp generally clamps the transmission shaft through two movable clamping seats. This method will cause the transmission shaft to be unable to move after clamping, which makes it inconvenient to operate when grinding the outer wall, affecting the processing effect.
