Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a workpiece fixture for detecting defects of mechanical parts. Background Art

[0002] During the processing and testing of spare parts, they usually need to be clamped and fixed to facilitate processing and testing of the spare parts.

[0003] A Chinese patent with application publication number CN217168162U discloses an automatic tooling for special-shaped clamps for processing spare parts of testing equipment. In this patent, when in use, the workpiece is placed inside the placement groove, and the motor is started at this time, so that the first sliders at the ends of both sides are simultaneously retracted inward. After the sticking block contacts the workpiece, it will rotate and stick to the workpiece along with the rotating shaft according to the shape of the workpiece. As the direction of rotation increases, the first slider slides inside the motor and compresses the spring, making the clamping more secure. When the first slider is tightened against the outer wall of the workpiece, the roller will rotate against the outer wall of the workpiece, which can effectively protect the outer wall of the workpiece from scratches and can also effectively clamp various special-shaped workpieces.

[0004] When using the above patent, we found that the device does not have the ability to drive the spare parts to rotate. When the positions of the spare parts to be inspected are different, the inspection effect of the spare parts is affected. Therefore, we proposed a workpiece fixture for defect detection of mechanical spare parts. Summary of the invention
