AI Technical Summary
Existing angled hole drilling fixtures are not fast enough in fixing and releasing workpieces, and cannot adjust the fixing angle according to processing requirements, thus limiting their applicability.
A clamping fixture comprising a base, a support plate, a support arm, and a pressure plate was designed. The workpiece can be quickly clamped and released by flipping the support arm to drive the pressure plate. The angle of the support plate can be adjusted by locking screws and connecting seats to adapt to different processing requirements.
It enables rapid clamping and release of workpieces, improves the efficiency of continuous processing of multiple workpieces, and can adjust the fixed angle according to requirements, thereby enhancing the stability and applicability of the workpieces.
