Description
technical field [0001] The invention relates to the technical field of product hydraulic clamps, in particular to hydraulic clamps for cantilever long parts. Background technique [0002] In the automobile engine part, there are a large number of parts, among which long cantilever parts are relatively common. Due to the overhang of the cantilever, it is difficult to process the cantilever. In order to ensure the stability of the processing, it needs to be fixed. The existing positioning device is difficult. Ensure that it is reliably fixed, and it is prone to shaking during processing, which affects processing stability and reduces the qualified rate of parts. Contents of the invention [0003] In order to solve the problems of poor stability of fixed and processed parts and low pass rate of parts, the invention provides a hydraulic clamp for cantilever long parts, which can realize reliable fixing of parts, ensure processing stability, and improve pass rate. [0004] Its...
