A clamping fixture for crack detection in clutch housing

Abstract

The invention discloses an internal crack detection clamp for a clutch housing. The internal crack detection clamp comprises a workbench, and a backing plate is arranged at the top of the workbench. Aclamp body is arranged at the top of the backing plate, and a push plate is arranged at the bottom of the inner side of the clamp body. A connecting rod is arranged at the bottom of the push plate, and an electric-driven push rod is arranged at the bottom of the connecting rod. A telescopic cylinder is arranged between the electric-driven push rod and the connecting rod, and a spring is arrangedin the telescopic cylinder. An annular frame is arranged at the top of the clamp body, and an arc-shaped frame is arranged at the top of the annular frame. A tooth groove is formed in the inner side of the arc-shaped frame, and a sliding block is arranged in the arc-shaped frame. A sliding rail is arranged at the joint of the sliding block and the arc-shaped frame. According to the internal crackdetection clamp, the annular frame, the arc-shaped frame and the sliding block are arranged, a crack detector is arranged on the surface of the sliding block, therefore the surface of the clutch housing is detected by the crack detector, and the detection efficiency is high.

Description

technical field [0001] The invention relates to clutch housing testing equipment, in particular to a clamping fixture for detecting cracks in the clutch housing. Background technique [0002] Clutches are widely used in the automobile industry and are important parts of automobiles. They play an essential role in the transmission of power and movement of automobiles. At present, the forming of automobile clutch housings has progressed from traditional gravity casting to pressure casting. The clutch housing produced by the die-casting process has a draft angle in the casting, and the dimensional accuracy of the casting cavity is poor. The existing clamping fixture for crack detection, the crack detector installed in it is fixedly connected, and cannot fully detect the workpiece. The detection efficiency is low, and the clutch housing is not easy to be taken out after the clutch housing is fixed by the clamp, which affects the work efficiency. [0003] Therefore, it is necess...
