Technical Field

The invention relates to the field of motion mode conversion, in particular to a structure for converting linear reciprocating motion into unidirectional stepping motion.

Background

At present, due to the limitation of transmission structure and transmission form, a structure for converting linear reciprocating motion into unidirectional stepping motion is needed in various mechanical transmission fields. The mechanism is a structure which requires that reciprocating active parts such as an air cylinder, a hydraulic oil cylinder and the like are adopted as driving force, and finally converted into unidirectional motion through a mechanical transmission structure and has the characteristic of stepping motion.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

As shown in fig. 1 and 2, the invention relates to a structure for converting linear reciprocating motion into unidirectional stepping motion, which comprises a rack 1, a rack seat 2, a gear 3, a ratchet 4, a spring 5, a pawl 6, a key 7, a shaft 8 and a bearing 9, and is characterized in that: the rack seat 2 is horizontally arranged, and a rack 1 is arranged in the rack seat 2; a gear 3 is arranged at the upper part of the rack seat 2, and the gear 3 is meshed with the teeth on the rack 1; a ratchet wheel 4 is arranged at the center of the interior of the gear 3, a pawl 6 is arranged at the upper part of the ratchet wheel 4, the pawl 6 is arranged in a gap formed in the middle of the gear 3, and a spring 5 is arranged at the rear part of the pawl 6 and can move up and down under the elastic force of the spring 5; a shaft 8 is arranged in the middle of the ratchet wheel 4, and the shaft 8 is connected with the ratchet wheel 4 through a key 7; the bearing 9 is arranged between the shaft 8 and the gear 3, so that the gear 3 and the shaft 8 can not move synchronously.

When the ratchet wheel is used, when the rack 1 moves rightwards, the gear 3 rotates anticlockwise, the pawl 6 arranged inside the gear 3 cannot drive the ratchet wheel 4 to rotate due to the angle, the spring 5 is compressed at the moment, and the shaft 8 in the middle of the ratchet wheel 4 cannot rotate; when the rack 1 moves leftwards, the gear 3 rotates clockwise, the pawl 6 arranged in the gear 3 also drives the ratchet wheel 4 to start rotating, at the moment, the spring 5 pops out, and the ratchet wheel 4 drives the middle shaft 8 to rotate; when the rack 1 continuously reciprocates, the shaft 8 rotates in the same direction at intervals to complete the process of converting the linear reciprocating motion into the unidirectional stepping motion of the whole structure.

By adopting the structure, the invention converts the linear reciprocating motion into the unidirectional stepping motion structure to be introduced into the mechanical transmission structure, thereby realizing the conversion from the linear reciprocating motion to the unidirectional stepping motion under special requirements, meeting the mechanical transmission requirements and increasing the diversity of mechanical transmission forms.
