High-speed linear reciprocating motion mechanism

Abstract

The invention discloses a high-speed linear reciprocating motion mechanism. The mechanism comprises a driving part and a movable part, the top end of the driving part is linked with a power source, and the power source controls the driving part to rotate around the axis. A circle of ball ring with the axis as the center is arranged on the bottom end face of the driving part and comprises a plurality of ball sections and the interval sections arranged between the adjacent ball sections, and each ball section comprises a plurality of driving balls which are uniformly arranged and mounted by taking the axis as the center; a ball groove matched with the ball ring is formed on one end face of the movable part and comprises a plurality of plane sections and protruding sections, and the plane sections and the protruding sections correspond to the ball sections and the interval sections in a one-to-one correspondence manner. The driving balls are attached to the bottoms of the plane sections,the bottoms of the protruding sections are arranged in a protruding manner, and the protruding height is smaller than the height of the driving balls exposed out of the bottom face of the driving part. The high-speed linear reciprocating motion mechanism is simple in structure, very low in cost and long in service life, is capable of conducting the ultra-high-speed linear reciprocating motion, issuitable for various linear reciprocating motion scenes, and enables the effect to be greatly improved.

Description

technical field [0001] The invention relates to the technical field of rotating accessories, in particular to a high-speed linear reciprocating mechanism. Background technique [0002] High-speed punch feeders, high-speed opening and closing valves and other equipment widely have high-speed reciprocating linear motion scenes. The high-speed reciprocating linear motion is used to control the rapid clamping and loosening of the feeding workpiece and realize the rapid opening and closing of the valve. Existing linear reciprocating motion mechanisms are generally realized by cylinders, servo motor screw rods and other mechanisms, and the control inevitably has forward and reverse switching, the frequency of reciprocating linear motion is not high, and the service life and accuracy of the motion mechanism are not high. high. With the popularization of equipment such as ultra-speed punch feeders and ultra-high-speed opening and closing valves, more efficient, low-cost, and long-l...
