Abstract
The invention discloses a reciprocating mechanism which comprises two symmetrical cylindrical cams. The curve contour surfaces of the upper cylindrical cam and the lower cylindrical cam are oppositely installed in a connecting sleeve to form a cam assembly and oppositely form a curve groove. A main shaft is axially installed in the cam assembly. Slide rods are transversely connected to the main shaft and penetrate through the curve groove. A motor rotates at a high speed to drive the upper cylindrical cam and the lower cylindrical cam to rotate at a high speed so as to drive the slide rods to move along the track of the curve groove. The radial direction of the main shaft is fixed, and therefore the slide rods move along the curved surface tracks of the upper cylindrical cam and the lower cylindrical cam to drive the main shaft to reciprocate linearly. The slide rods on the two sides of the main shaft are driven by the two symmetrical cylindrical cams to move along the curved surface tracks of the two cylindrical cams so as to drive the main shaft to reciprocate linearly. The reciprocating mechanism is simple in overall structure, high in instantaneous intensity resistance and not prone to damage, and the two sides of the main shaft bear force uniformly when the reciprocating mechanism is started.
