Abstract

The utility model relates to a reciprocating motion mechanism adopting belt transmission. The reciprocating motion mechanism adopting belt transmission consists of a driving belt wheel 1, a driven belt wheel 2, a transmission flat belt 3, a shifting pin shaft 4, a reciprocating movement block 5 and a movement block guide rail 6. An 'n'-shaped shifting fork is arranged on the reciprocating movement block 5, and the shifting pin shaft 4 is arranged at the connector position 301 of the transmission flat belt 3 and installed in the 'n'-shaped shifting fork on the reciprocating movement block 5. When the driving belt wheel 1 rotates, the transmission flat belt 3 and the driven belt wheel 2 are driven to move, and the shifting pin shaft 4 on the transmission flat belt 3 shifts the reciprocating movement block 5 to achieve reciprocating motion.

Description

A belt drive reciprocating motion mechanism

technical field

The utility model relates to a reciprocating mechanism, in particular to a belt-driven reciprocating mechanism. the

Background technique

Reciprocating motion is one of the common motion modes in mechanical equipment. Commonly used reciprocating motion mechanisms include crank slider mechanism, cam mechanism, etc., but when the distance of reciprocating motion is large, the structural size of these mechanisms will become large. Therefore, there is a need for a mechanical transmission mechanism that can realize long-distance reciprocating motion and has a small structure. the

Contents of the invention

The purpose of the utility model is to provide a belt drive reciprocating mechanism. the

The technical scheme of the utility model: the belt-driven reciprocating mechanism consists of a driving pulley (1), a driven pulley (2), a driving flat belt (3), a toggle pin (4), and a reciprocating block (5) It is composed of moving block guide rail (6); there is an "n" shaped shift fork on the reciprocating moving block (5), and there is a toggle pin (4) at the joint (301) of the transmission flat belt (3). The moving pin shaft (4) is installed in the "n" shape shift fork on the moving reciprocating block (5), and is used to stir the reciprocating moving block (5) to realize reciprocating motion. the

Beneficial effects: the belt-driven reciprocating mechanism has a simple structure and is easy to manufacture, and the size of the mechanism is small when the reciprocating distance is large. the

Detailed ways

According to Fig. 1, Fig. 2 and Fig. 3, the specific embodiment of the utility model is described in detail. the

From Fig. 1, Fig. 2 and Fig. 3, we can see the structural characteristics of the belt-driven reciprocating mechanism. , the reciprocating block 5 and the moving block guide rail 6; there is an "n" shaped shift fork on the reciprocating block 5, and there is a toggle pin 4 on the joint 301 of the transmission flat belt 3, and the toggle pin 4 Installed in the "n" shaped shift fork on the reciprocating moving block 5; when the driving pulley 1 rotates, it drives the driving flat belt 3 and the driven pulley 2 to move, and the toggle pin 4 on the driving flat belt 3 moves The reciprocating block 5 realizes reciprocating motion. the

In order to change the sliding friction into rolling friction when the toggle pin 4 toggles the reciprocating block 5, a rolling bearing can also be installed on the toggle pin 4. the
