Problems solved by technology

[0003] This inner ratchet has a one-way braking effect and prevents the ratchet from rotating during transmission. At the same time, this ratchet mechanism also has the following technical problems. This ratchet mechanism can only brake in one direction, that is, it can only After the ratchet rotates, the inner ratchet is prevented from rotating, but the ratchet cannot achieve braking in its direction of rotation, and the ratchet is easy to rotate excessively, especially for some equipment with high transmission precision. If the traditional ratchet is used, the braking will not be complete. less effective problem

Embodiment Construction

[0028] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0029] To facilitate understanding, Figure 4 , Figure 5 The arrow in the middle indicates the direction of rotation of the inner ratchet 110, which is a forward rotation.

[0030] Such as figure 1 As shown, a bistable ratchet mechanism of the present invention is installed on the frame 1 and includes a rotating shaft 100 and an inner ratchet 110. The frame 1 is also provided with a conveying device connected to the rotating shaft for conveying workpieces. The rotating shaft 100 The two ends of the shaft are respectively connected to the frame 1, and one end of the rotating shaft 100 penetrates the frame 1 and extends out of the frame to form a transmission part. The inner ratchet 110 is installed on the transmission part, such as fi...

Abstract

The invention provides a bidirectional brake ratchet mechanism, belongs to the technical field of ratchets, and aims to solve the technical problem that the existing racket can only be braked uni-directionally and has a poor brake effect. The bidirectional brake ratchet mechanism comprises a rotating shaft, a transmission shaft and a forward stop block, wherein the rotating shaft is provided with an inner racket which rotates uni-directionally; the inner racket is provided with a plurality of tooth blocks; the transmission sleeve sleeves the rotating shaft and is connected with a push block; one end of the push block is abutted against the tooth blocks; the inner racket can be pushed to rotate during forward rotation of the tooth blocks; the forward stop block is adjacent to the inner racket; when the tooth blocks are in contact with the forward stop block, the inner racket stops rotation, the transmission sleeves rotates reversely and the forward stop block can be pushed to move; when the forward stop block is separated from the tooth blocks, the inner racket can continuously rotate; the stop device realizes bidirectional brake of the inner racket in a stop state of the inner racket, so the phenomenon of revolving of the inner racket is prevented, meanwhile over rotation of the inner racket is prevented, and the brake effect of the mechanism is good.

Description

Technical field [0001] The invention belongs to the technical field of ratchets, and relates to a ratchet mechanism, in particular a bidirectional brake ratchet mechanism. Background technique [0002] The ratchet mechanism is a common transmission mechanism, which is mainly composed of a rocker, a pawl and an outer ratchet. The rocker is the motion input member, and the ratchet is the motion output member. When the rocker swings clockwise, the pawl hinged on the rod is inserted into the teeth of the ratchet wheel, so that the ratchet wheel rotates through a certain angle at the same time. When the rocker rod swings continuously back and forth, the ratchet wheel obtains unidirectional intermittent rotation. [0003] This kind of inner ratchet has a one-way braking effect and prevents the ratchet from rotating during transmission. At the same time, this kind of ratchet mechanism also has the following technical problems. This kind of ratchet mechanism can only brake in one directio...
