Problems solved by technology

[0003] Most of the existing ratchet mechanisms use a single pawl structure, which has low precision and cannot meet the high-precision requirements of the action.
As for the micro-sized ratchet that meets the high-precision action, the tooth processing technology of the ratchet is complicated and difficult to realize. In addition, the precision of the ratchet mechanism is small, which makes it difficult to manufacture elastic elements such as the spring for the return of the pawl, and cannot meet the precise return of the pawl. bit

specific Embodiment

[0019] Such as figure 1 and figure 2 As shown, a specific embodiment of the present invention is proposed, a multi-claw ratchet mechanism, including a rocker 1, and a hollow support ring 2 is provided on the rocker 1. In this embodiment, the rocker 1 has an end rod for supporting The support ring 2 is provided with several circular holes 2-1. In this embodiment, 8 circular holes 2-1 are preferably arranged, and the 8 circular holes 2-1 are hinged with magnetic material. The other ends of the ratchets 4 and 8 are all attached to the ratchet 3 located in the round hole of the support ring 2, and one side of the ratchet 3 is provided with ring magnets 5 and 8 that can make the ratchet 4 generate magnetic force A magnetic force is formed between the ratchet 4 and the ring magnet to attach to the teeth of the ratchet 3. In this embodiment, adjacent ratchets 4 are evenly spaced by 25 / 8 teeth, and the rocker 1 swings 8 times, and the ratchet 3 After turning a tooth pitch angle, th...

Abstract

The invention discloses a ratchet mechanism, comprising a rocker, wherein the rocker is provided with a hollow supporting ring, the supporting ring is provided with a plurality of round holes, each round hole is hinged to a pawl made of a magnetic material, the other ends of the pawls are all attached to ratchets located in the round holes of the supporting ring, one side of the ratchet is provided with an annular magnet; the rocker, the supporting ring, the ratchet and the annular magnet are connected with one another by a rotation shaft, two ends of the rotation shaft are respectively provided with an axial fastener, and the rotation shaft and the rocker, the rotation shaft and the annular magnet are all in clearance fit connection, and the rotation shaft and the ratchet, the rotation shaft and the fastener are all in interference fit connection. By arranging the multiple pawls and enabling the pawls to return by magnetic force, the ratchet mechanism has the advantages of high moving accuracy, simple processing technology, stable action, good practicability and the like, and is worth popularizing widely.

Description

technical field [0001] The invention relates to an intermittent motion mechanism, in particular to a ratchet mechanism. Background technique [0002] The ratchet mechanism is a simple and widely used intermittent motion mechanism that converts continuous rotation or reciprocating motion into unidirectional stepping motion. The ratchet mechanism is mainly made up of rocking bar, ratchet and outer ratchet. The rocker is a motion input component, and the ratchet is a motion output component. When the rocker swings clockwise, the pawl hinged on the rod is inserted into the teeth of the ratchet, so that the ratchet rotates through a certain angle at the same time. When the rocker swings counterclockwise, the pawl slides over the teeth of the ratchet, and the ratchet stands still. [0003] Most of the existing ratchet mechanisms adopt a single pawl structure, which has low precision and cannot meet the high-precision requirements. As for the micro-sized ratchet that meets the ...
