Abstract

The invention discloses a one-way rotating crank mechanism, and aims at solving the problem that a machine tool rotary motion mechanism in the prior art is incapable of realizing one-way motion. The one-way rotating crank mechanism comprises a frame, a driving wheel arranged on the frame, a driven shaft slidingly connected with the frame and a driven wheel fixed with the driven shaft, and also a crank and a gear connected with the driven shaft through a one-way bearing, wherein a plurality of hinging holes are formed in the crank, one end of the crank is hinged to the rim of the driving wheel, while the other end of the crank is hinged to an axially movable sliding rod, the two ends of the sliding rod are slidingly connected with the frame, a section of rack is arranged on the middle part of the sliding rod, and the rack is engaged with the gear. The one-way rotating crank mechanism is simple in structure and high in practicability.

Description

Crank unidirectional rotary mechanism
Technical field
The present invention relates to machine tooling technical field, be specifically related to a kind of crank unidirectional rotary mechanism.
Background technique
In machine tool rotary working table, commonly use rotation motion mechanism, what rotation motion mechanism was conventional is Geneva mechanism, but in actual use, Geneva mechanism remains in certain deficiency, traverse is unadjustable, corner can not be too little, cannot realize unidirectional movement, and the acceleration of sheave when starting and stopping is large, there is impact, and along with the increase of rotating speed or the minimizing of sheave groove number and aggravate, therefore should not be used for high-speed motion, multiplexly realize the transposition campaign that does not need frequent regulating rotary parallactic angle degree.
Summary of the invention
The invention is intended to provide a kind of crank unidirectional rotary mechanism, to solve machine tool rotary motion in prior art, cannot realize the problem of unidirectional movement.
Crank unidirectional rotary mechanism in this programme, the driven shaft that comprises frame, is located at driving wheel in frame, is slidably connected with frame and with the fixing follower of driven shaft, also comprise crank and the gear being connected by unilateral bearing with driven shaft, crank is provided with multiple hinging holes, hinged driving wheel wheel rim place, crank one end, crank the other end hinging shaft is to sliding bar movably, and sliding bar two ends and frame are slidably connected, sliding bar middle part is provided with one section of tooth bar, and described tooth bar engages with described gear.
Compared with prior art, advantage of the present invention is: crank rotates, and drives sliding bar to-and-fro motion, when sliding bar forward slides, rack drives gear forward on sliding bar, by individual event bearing, drive driven shaft forward, and then drive follower forward, when sliding bar reverse slide, rack drives gear reversion on sliding bar, and individual event bearing can only move towards a direction, thus gear idle running, and follower cannot rotate with gear; So just realized the unidirectional movement of follower; The present invention is simple in structure, processing ease.
Further, frame and the sliding bar place of being slidably connected are provided with abrasive rubber cover, avoid the direct contact wear of sliding bar and frame.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of crank unidirectional rotary mechanism for implementing example of the present invention.
Embodiment
Shown in Fig. 1, crank unidirectional rotary mechanism in the embodiment of the present invention, comprise frame, be located at the driving wheel 1 in frame, the driven shaft 5 being slidably connected with frame and with the fixing follower 4 of driven shaft 5, also comprise crank 2 and the gear being connected by unilateral bearing with driven shaft 5, crank 2 is provided with multiple hinging holes, crank 2 hinged driving wheel wheel rim places, one end, crank 2 the other end hinging shafts are to sliding bar 3 movably, sliding bar 3 two ends and frame are slidably connected, sliding bar 3 middle parts are provided with one section of tooth bar, described tooth bar engages with described gear, frame and sliding bar 3 places of being slidably connected are provided with abrasive rubber cover.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.

Claims (2)

1. a crank unidirectional rotary mechanism, the driven shaft that comprises frame, is located at driving wheel in frame, is slidably connected with frame and with the fixing follower of driven shaft, it is characterized in that: also comprise crank and the gear being connected by unilateral bearing with driven shaft, crank is provided with multiple hinging holes, hinged driving wheel wheel rim place, crank one end, crank the other end hinging shaft is to sliding bar movably, sliding bar two ends and frame are slidably connected, sliding bar middle part is provided with one section of tooth bar, and described tooth bar engages with described gear.
