Abstract

The utility model provides a mechanism which can realize the conversion from rotation motion to linear reciprocating motion. The utility model is characterized in that: the rotation motion is input through a camshaft [1]; the camshaft [1] drives a cam [2] to rotate; the cam [2] closely clings to a flat-bottom driven seat [3] under the function of a spring force of a spring [4]; when the cam [2] performs lift motion, the cam [1] pushes the flat-bottom driven seat [3] and a transmission shaft [6] to perform linear motion; when the cam perform descending motion, the flat-bottom driven seat [3] pushes the transmission shaft [5] to perform linear drawback motion. Thus stable and continuous reciprocating motion of the transmission shaft [5] under the alternative function of the pushing force of the cam [2] and the spring force is realized.

Description

Cammingly to-and-fro motion switching mechanism

Technical field

The utility model relates to a kind of being used for transhipment is converted to reciprocating mechanism.

Background technique

Thin bamboo strip first procedure of domestic artificial bamboo board and articles made of bamboo braiding is to remove the blue or green layer of mao bamboon epidermis.This procedure has at present by manually utilizing the reciprocating blue or green layer of mao bamboon epidermis of removing of light instrument; It is the demand of industrialized production that machinery is removed the blue or green layer of mao bamboon epidermis, mao bamboon removes blue or green Realization by Machine and removes the blue or green layer of mao bamboon epidermis, main movement is the to-and-fro motion of cutter, needs compact structure, the reliable mechanism that moves, and is realized changing rotatablely moving of motor output into to-and-fro motion by this mechanism.

Summary of the invention

In order to realize changing rotatablely moving of motor output into to-and-fro motion, the utility model provides a kind of compact structure, the reliable cam mechanism that moves, and changes the rotation of motor output shaft into to-and-fro motion, and the to-and-fro motion stroke of mechanism's output is fixed, motion steadily there is not vibration.

The technological scheme that its technical problem that solves the utility model adopts is:

Transmission shaft carries out with flat driven seat that groove-fastening type is movable to be connected, and guide pin bushing is contained on the base in the mode of transition fit, and transmission shaft passes spring, is contained in the guide pin bushing in movingly mode, can reciprocatingly slide.Flat driven seat is close to all the time with the cam circumferential end surfaces under the effect of spring force, and it is reciprocating that Zhuan Yun cam will promote flat driven seat like this, and flat driven seat drives transmission shaft output to-and-fro motion.

The beneficial effects of the utility model are, motor drives the cam transhipment by camshaft, and spring makes flat driven seat band be close to cam, makes transmission shaft output straight reciprocating motion.Realization is input as and rotatablely moves, and is output as to-and-fro motion, and the to-and-fro motion stroke equals the difference of the length diameter of axle of cam.

Description of drawings

Accompanying drawing is a cammingly to-and-fro motion switching mechanism structural drawing

In the accompanying drawings, 1. camshaft, 2. cam, 3. flat driven seat, 4. spring, 5. transmission shaft, 6. guide pin bushing, 7. base.

Embodiment

In the accompanying drawings, rotatablely move by camshaft [1] input, camshaft [1] drives cam [2] transhipment, cam [2] is under the effect of the spring force of spring [4], be close to flat driven seat [3], when cam [2] is done the lift motion, cam [1] can promote flat driven seat [3] and transmission shaft [5] moving linearly, when Cheng Yundong falls in cam, flat driven seat [3] can be under the effect of spring force, promote transmission shaft [5] and make the straight line drawback movement, under the thrust that forms cam [2] like this and the alternating action of spring force, realize transmission shaft [5] stable continuous to-and-fro motion under guide pin bushing [6] guides.

Claims

1. a realization will rotatablely move and be converted to the mechanism of straight reciprocating motion, its technical feature of structure is: transmission shaft carries out the groove-fastening type activity with flat driven seat and connects, guide pin bushing is contained on the base in the mode of transition fit, transmission shaft passes spring, be contained in the guide pin bushing in movingly mode, can reciprocatingly slide, flat driven seat is under the effect of spring force, all the time be close to the cam circumferential end surfaces, it is reciprocating that cam promotes flat driven seat, and flat driven seat drives transmission shaft and does straight reciprocating motion.
