How to Conduct Fixture Inspection and Detection in Precision Parts Processing

After a malfunction occurs during the processing of precision parts, the fixture should first be inspected and tested according to the fixture assembly drawing and technical requirements. The inspection content and steps are as follows:

1. Inspect and inspect the positioning surface of the positioning element to determine if the positioning element is damaged or worn beyond the limit value. Whether the wear of support parts such as support nails, support plates, positioning pins, adjustable supports, and self positioning supports is within the limit value range.

2. During the processing of precision parts, the clamping components, devices, and mechanisms are inspected and tested, such as whether the pressure plate is deformed, whether the tooth profile of the toothed pressure plate is damaged, whether the cushion block or support screw is displaced or damaged, whether there are leaks and motion faults in the pneumatic hydraulic device, whether the eccentric wheel of the eccentric mechanism is damaged or exceeds the wear limit, and whether the wedge fitting of the oblique wedge clamping mechanism meets the accuracy requirements Whether the screw transmission pair of the screw clamping mechanism is damaged, and whether the mechanical transmission components of the linkage clamping mechanism are intact.
