The working process is as follows: referring to fig. 1 to 13, in the above-mentioned insertion, extraction and torsion checking machine after a key is assembled to a padlock, firstly, a lock workpiece with a assembled key is discharged into a feeding groove 23 until a first baffle 224 (at this time, a second telescopic cylinder 225 is in an extended state, and the first baffle 224 is pushed to stop the lock workpiece from falling down), at this time, a first sensor 231 triggers a first clamp 221 to clamp the lock workpiece, and at the same time, the second telescopic cylinder 225 is contracted to pull back and push the first baffle 224, and push a second baffle 230 to make the lock workpiece blocked on the first baffle 224 fall onto the second baffle 230 (when the lock workpiece on the first baffle 224 falls, a second sensor works and triggers the first clamp 221 to release the previously clamped lock workpiece while triggering the first baffle 224 to stop the second lock workpiece falling from the first clamp 221, at this time, the lock workpiece on the feeding groove 23 automatically falls down to trigger the first sensor 231 again, then triggering the first clamp 221 to clamp the lock body workpiece again); at this time, the third sensor 232 works and triggers the second clamp 226 to push out to clamp a lock body workpiece, then the plug-pull torsion mechanism 3 is triggered to work, at this time, the first push-pull cylinder 312 on the plug-pull transmission mechanism 31 pushes the plug-pull torsion mechanism 3 to enable the clamping jaw 373 to align with a key inserted in the lock body workpiece, then the transmission cylinder 370 pushes the clamping jaw 373 to clamp the key, then the second push-pull cylinder 323 completes the pulling and pushing action, then the second rotation cylinder 340 completes the rotation action, after that, the plug-pull torsion mechanism 3 resets, then the second clamp 226 and the second baffle 230 reset are triggered, at this time, the lock body workpiece falls into the turning column 244, then the first rotation cylinder 243 rotates 90 degrees, and then the discharge cylinder 242 pushes the lock body workpiece to the groove-shaped discharge rail 241 and resets to wait for the next lock body workpiece; the operation is circulated, so that the insertion, extraction and torsion checking machine of the padlock after the key is assembled can complete the work.

The actions are reciprocating actions under the condition that the lock body workpiece is qualified, and when an unqualified lock body workpiece is detected, a set of actions is added: the condition that the workpiece is not matched means that the key cannot be inserted, pulled out and rotated, the triggering lug 343 cannot reach the third inductor 333, then the third inductor 333 triggers the sliding baffle 228 to slide out of the gear and the second clamp 226 to release, then the pushing cylinder 25 works to push the unqualified lock body workpiece out of the blanking groove 22b and drop the unqualified lock body workpiece into the counterfeit product blanking hopper 13, then the sliding baffle 228 is reset, and the equipment continues to perform the inspection action.
