Embodiment Construction

[0013] Such as figure 1 As shown, a low-speed intermittent rotary mechanism includes a seat body 1, on which there is a camshaft 2 driven by a driving device, the end of the camshaft 2 is eccentrically provided with an eccentric end cam 3; the eccentric end cam 3 is provided with a The rack 4 that can swing up and down and move back and forth is located above the rack 4 and is provided with a gear 5 that meshes with the rack 4 when it swings up; Fitted hook 6, when the eccentric end cam 3 rotates away from the axis to the upper side, it pulls the rack 4 to swing upwards, and the protruding contour on the end surface of the eccentric end cam pushes the rack 4 forward to drive the gear 5 to rotate When the eccentric end face cam 3 rotates downward away from the side of the axis, the rack 4 will also swing downwards due to its own weight to break away from the gear 5 and fall on the support platform 7 of the seat body to limit its continued hem; the end face of the eccentric end ...

Abstract

The invention relates to a low-speed intermittent rotating mechanism and a working method thereof. The low-speed intermittent rotating mechanism comprises a seat body; the seat body is provided with a cam shaft driven by a driving device to rotate, and the end of the cam shaft is provided with an eccentric end cam which is eccentrically arranged; a rack capable of vertically swinging and moving back and forth is arranged above the eccentric end cam, and a gear meshed with the rack when the rack upwards swings is arranged above the rack; and the front end of the rack is provided with a hook part which is downwards bent and is fitted with the end of the eccentric end cam, when the side, far away from an axis, of the eccentric end cam rotates to the upsides, the eccentric end cam drags the rack to upwards swing, and a raised profile on the end of the eccentric end cam pushes the rack to forwards move to drive the gear to rotate. The low-speed intermittent rotating mechanism disclosed by the invention is good in stability and reliability, high in efficiency, adjustable in rotation angle and convenient to use.

Description

technical field [0001] The invention relates to a low-speed intermittent rotary mechanism and its working method. Background technique [0002] Intermittent rotary motion mechanisms are often used in machine tools, and the current way to realize intermittent rotary motion is usually to use a slotted wheel mechanism. Since the structure of the slotted wheel cannot be changed, the rotation angle cannot be adjusted. If you want to achieve adjustment, you need to replace the slotted wheel, so it is not easy to use. Convenience; and other mechanisms that realize intermittent rotation basically have the problems of poor stability, reliability and low efficiency. How to improve the reliability of such mechanisms has become a topic worthy of research. Contents of the invention [0003] In view of this, the object of the present invention is to provide a stable, reliable, high-efficiency low-speed intermittent rotary mechanism and its working method. [0004] The present invention...
