[0035] Working principle
[0036] In actual use, the preliminary work involves first installing the pedal mounting plate 2 onto the slide mechanism 5 and locking it in place using pin-hole positioning bolts. Then, the pedal workpiece 3 is inserted into the pedal mounting plate 2, and the bushing is fitted into the bushing pressing head 8. Simultaneously, a fault-prevention sensor 7 detects the bushing to ensure smooth insertion of the bushing and pedal workpiece 3. Afterward, the automatic assembly PLC program is started to begin automatic assembly. Once the automatic assembly program starts, the pedal workpiece 3 clamping mechanism automatically clamps the pedal workpiece 3, while the slide cylinder 6 pushes the slide mechanism 5 to the upper travel limit block. At position 11, the press-fit cylinder 9 starts working and pushes the bushing press-fit head 8 to insert the bushing into the pedal. After assembly, the press-fit head retracts to the initial position. During this process, the stroke position is detected by the inductive switch to determine whether the bushing is installed in place and whether it has retracted to the initial position. When the slide cylinder 6 pushes the slide mechanism 5 to the lower stroke limit block 12, the oil injection head in the oil injection mechanism 13 will press into the bushing hole to inject grease. After completion, the oil injection machine retracts to the initial position, the pedal fixing plate 2 retracts to the initial position, and finally the assembled product is taken out to prepare for the next assembly cycle.
