Detailed Description
Referring to fig. 1, the press-fitting tool for assembling the motor output shaft flat key comprises a key groove guide block 1; the key groove guide block consists of a fixed block 2 and a support rod 3; the center of the fixed block below the supporting rod is provided with a mounting hole 4 matched with the shape of the shaft outlet end of the motor, the top surface of the supporting rod is provided with two mounting blocks 5, and the mounting blocks correspond to the two side edges of the fixed block one by one; the mounting blocks are all provided with rotatable key press joints 6. The key is assembled on the motor shaft and pushed into the round hole of the fixed block shown in the figure. The polishing of the inner hole of the fixed block can ensure that the motor shaft has no rotation, no scratch and no stress.
The mounting hole is the round hole and is equipped with the keyway 7 that can supply the key to place on the fixed block on mounting hole top, this keyway and round hole intercommunication. The structure that adopts keyway and round hole intercommunication and motor shaft appearance more adaptation, follow-up installation is more convenient.
The supporting rod above the key groove is provided with a slot, and a moving block 9 capable of moving up and down is arranged in the slot.
Further comprises a mounting base 10; one end of the mounting base is provided with a driving component for driving the key press joint to rotate, and the other side of the mounting base is provided with a motor driving component 12 for driving a motor to do reciprocating motion. The motor driving component is arranged to drive the motor to reciprocate back and forth, so that the motor shaft is conveyed into the mounting hole; the driving assembly drives the key pressing joint to rotate so as to enable the moving block located below the key pressing joint to do reciprocating motion, and the key located below the moving block is pressed into a key groove of the motor shaft at the moment; the movement block drives the key press joint to rotate through the drive assembly when pressed down.
The moving block consists of a U-shaped frame 9.1 and a vertical rod 9.2. The U-shaped frame is erected on the supporting rods at two sides (the front side and the rear side of the slot) of the slot through the extending blocks 9.3 arranged at the top ends of the two sides, and the vertical rod is inserted into the slot and can move up and down in the slot.
