Depending post 365 drives match wheel 371 to rotate, and then match wheel 371 drives the castor 372 of behind to do circumference fortune in rotation
Dynamic, then motion bar 373 is along the movement of castor 372 so that motion bar 373 drives transmission with shaft 374 for center of rotation
Lever 376 moves, and then moves lever 376 and jacks up upwards, so that movable frame 381 moves in a circle to the left, promotion is pushed away in parallel
Bar 383 moves downward, and then collects and restores normal condition after pressing from both sides the obstruction that 385 lose fixed block 382, by underproof processing
Part, which clamps, to be withdrawn, and when the bar for collecting 385 tops of folder encounters fixed block 382 again, is opened upwards, then underproof processing
Part falls automatically and is recycled, and after being measured, control module 322 controls mobile device and is moved to aperture measurement device 32
Initial position.
If the aperture of workpiece meets the requirement in design aperture, automatically receiving device 3 is failure to actuate, after being measured,
Control module 322 controls workpiece mobile module 4 to be measured and continues to act, and qualified workpiece is conveyed to the defeated of downstream
Equipment is sent, the sorting of workpiece pieces O.K. and unqualified part is completed.
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above,
As long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or not improved by this
The conception and technical scheme of invention directly apply to other occasions, within the scope of the present invention.Guarantor of the invention
