A caliper piston defect detection device and a control method thereof
By designing a caliper piston defect detection device, a sealed cavity is formed by heating and cylinder-driven pressure head. The workpiece is controlled to be detected under high temperature and high pressure or low pressure conditions. This solves the problem of difficulty in detecting brake caliper piston cracks under high temperature conditions in the existing technology, and realizes efficient and safe defect detection.

AI Technical Summary
Technical Problem
Existing technologies are insufficient for effectively detecting cracks in brake caliper pistons under high-temperature conditions, and X-ray inspection methods are harmful to human health and costly.
Method used
A caliper piston defect detection device was designed. The detection oil is heated to a predetermined value by a heating device, and the pressure head is driven by a cylinder to press down to form a sealed cavity. The workpiece is controlled to be detected under high temperature and high pressure or low pressure. Defects are judged by changes in the liquid level.
Benefits of technology
It enables precise defect detection of caliper pistons under high-temperature conditions, improving the stability and safety of the detection and reducing harm to the human body.
