One channel, it is to carry out the production operation of next step, the piston circlip assembly of detection is underproof into same channel, be conducive to
Piston produces the development of assembly automation, reduces the labor intensity of worker, reduces cost of labor.
More specifically, the piston for installing clamp spring reaches piston pin assembly under the drive of carrier by clamp spring assembly station
Station；Guide-localization bar moves ahead under cylinder promotion, and is inserted into piston pin hole by clamp spring assembly side；At this time before guide-localization bar
The movable spring slice contact clamp spring at end is compressed；Lead to the gas output of the gas outlet on the guide-localization bar covered under movable spring slice
Reduce, the air pressure of pressure sensor input side is caused to increase；Pressure sensor records movable spring slice by compressed atmospheric pressure value；
According to movable spring slice by compressed atmospheric pressure value, setting the pressure threshold of pressure sensor, (its value will be slightly less than across clamp spring
Pressure sensor shows numerical value when assembling certified products)；Under normal detecting state, host computer is by the actual measurement air pressure of pressure sensor
Value is compared with preset pressure threshold value, if being equal to preset pressure threshold value, system display is qualified, continues next piston card
The detection of spring, wherein preset pressure threshold value are that pressure sensor shows numerical value when the clamp spring that a large number of experiments counts assembles certified products
The average value calculated float up and down 5% namely average value be multiplied by 95% and be multiplied by between 105% to average value；If small
In preset pressure threshold value, system shows unqualified, shifts piston onto defective products material path namely the second output channel；If clamp spring
It is not installed in place the gas outlet that just will appear in guide and locating mechanism to be closed by living spring component, judges that atmospheric pressure value is big at this time
In preset pressure threshold value, while guide-localization bar cannot enter in piston pin hole, and system shows unqualified, piston is shifted onto bad
Product material path namely the second output channel；It is detected cycle successively.
