Abstract

The invention discloses a high-frequency reciprocating motion mechanism, and the mechanism comprises a connecting plate, a sleeve, a motor, a reciprocating shaft, an elliptical wheel, a speed reducer,a static magnet, a moving magnet and a deep groove ball bearing. The connecting plate is an L-shaped plate, the speed reducer is installed on one side plate of the connecting plate, and an output rotating shaft of the speed reducer passes through the side plate. The elliptical wheel is mounted on the rotating shaft of the motor, and the output shaft of the motor is connected to the speed reducer,and the sleeve is mounted on the other side plate of the connecting plate. The reciprocating shaft slidably passes through the sleeve, the deep groove ball bearing is supported at the lower end of the reciprocating shaft, and the outer ring of the deep groove ball bearing abuts against the outer contour of the elliptical wheel. The static magnet is mounted on the lower surface of the other side plate of the connecting plate, and the moving magnet is mounted at the lower end of the reciprocating shaft, and the static magnet and the moving magnet repel each other. The mechanism is simple in structure, is steady in operation, is low in fault rate, and is long in service life.

Description

technical field

[0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a high-frequency reciprocating motion mechanism for converting circular motion into linear reciprocating motion. Background technique

[0002] In mechanical motion, reciprocating motion is a very common motion, which is generally realized by a crank slider mechanism. However, this method requires a huge torque to create a large reciprocating thrust. This kind of transmission mechanism often requires extremely high manufacturing costs, and the final transmission efficiency is not high, and there is an inertial impact at the dead point, and Since the slider crank mechanism generates high-frequency resistance during high-frequency reciprocating motion, the equipment will vibrate violently. In order to solve this problem, some use eccentric wheels. For example, on computerized cutting machines, eccentric wheels are used to realize the high-frequency recip...
