Abstract
The utility model relates to a reciprocating motion mechanism with a stroke adjustable. A main shaft is fixedly provided with a crank plate, a long groove and an adjusting bolt are arranged in the middle of the crank plate along a length direction, and the long groove and the adjusting bolt are used for transmitting main shaft bending moment and driving a crank to rotate. The adjusting bolt is provided with a spring in a sleeved mode, an adjusting block which can be attached to the crank plate to slide is arranged at the front end of the spring, and the adjusting block is used for adjusting the length of the crank plate. Locking bolts are arranged on two sides of the adjusting blocks and can be fixed with the crank plate in a screwing mode, and the locking bolts are used for fixing the adjusting blocks. A connecting rod is arranged in the middle of each adjusting block, a rotary pin shaft a is arranged between one end of the connecting rod and the adjusting block, and a sliding table is arranged at the other end of the connecting rod. The connecting rod is connected with the sliding table through a rotary pin shaft b, and a parallel rail is arranged below the sliding table. The reciprocating motion mechanism is adjustable in stroke, simple in structure and convenient to use.
