Automatic detection method and device for depth of piston clamp spring groove

Abstract

The invention relates to an automatic detection method and device for the depth of a piston clamp spring groove, and the device is characterized in that the device comprises a servo motor module, a laser detector, a laser detection clamp, a workpiece fixing clamp, and a gas detection device, which are disposed on a fixed pedestal. The gas detection device is arranged beside the workpiece fixing clamp, the driving output end of the servo motor module is connected with a laser detection head of the laser detector, the workpiece fixing clamp is provided with a limiting and fixing structure, the laser detector is fixedly arranged in the laser detection clamp, and the laser detection head of the laser detector faces a piston clamp spring groove of a workpiece. Reflected light received by the laser detector forms a depth detection signal of the piston clamp spring groove on the laser sensor, and the signal output end of the laser sensor is connected with the signal input end of the computer processor, so that the laser type automatic detection structure for the depth of the piston clamp spring groove is formed. The method has the advantages of mechanically and automatically detecting product quality, being low in labor cost and the like.

Description

technical field [0001] The invention relates to an automatic detection method and device for the depth of a piston ring groove. It belongs to the technical field of manufacturing equipment for automobiles and their accessories. Background technique [0002] In the existing production technology, a piston needs to go through nine processing steps from raw material to finished product. Wherein, the piston pin hole is processed at the station of the fourth processing procedure, and the ring groove is formed at the same time. The snap ring groove, as the name implies, is exactly the groove where the snap ring is placed. The piston circlip is a kind of fastener, and the circlip groove of the piston pin hole plays a role in preventing the axial movement of the piston pin. In the prior art, due to the occasional poor size of the circlip groove during the processing process, there is no special testing equipment, so it is necessary to use manual full size inspection to control pr...
