Abstract
The invention discloses a friction type cam unidirectional rotating mechanism. A push plate is pushed, and driving clamping blocks are driven by the push plate to move. On the one hand, the driving clamping blocks move horizontally; on the other hand, cams in the driving clamping blocks rotate around a rotary shaft till horizontal stop pins are located on the sides, moving close to the push plate, in sliding grooves, flanges of the cams are in contact with a rotary table, the cams and the driving clamping blocks drive the rotary table together to move, and then a driving shaft on the rotary table is used for output. The push plate is pushed reversely, the horizontal stop pins of the cams rotate in the horizontal sliding grooves, the cams are separated from contact with the rotary table, and therefore when the push plate is pushed reversely, the rotary table cannot be driven to rotate through the cams, and no driving output exists. Unidirectional clearance transmission of an output shaft is achieved through the cam structure.
Description
Technical field
The present invention relates to a kind of machinery processing apparatus, be specifically related to a kind of friction type cam one-way turning mechanism.
Background technique
Cam is revolution or the slider of machinery, it Movement transmit give near the roller of its edge movement or on groove face free-moving shank, or its strength from such roller and shank.In machining, need mechanism to possess the ability of single direction rotation, the mechanism that generally can realize single-direction transmission is a lot, but common mechanism runs stable not, cam generally can not be adopted to carry out transmission, therefore also do not possess the traditional plurality of advantages of cam.
Summary of the invention
The object of the present invention is to provide a kind of friction type cam one-way turning mechanism, single-direction transmission can be realized at dependence cam mechanism, and long service life, not fragile.
For achieving the above object, technological scheme of the present invention is: friction type cam one-way turning mechanism, comprise bearing, described bearing rotates and is provided with a rotating disk, on described rotating disk, key is connected with output shaft, described bearing slidably connects the driving fixture block driving rotating disk, and described driving fixture block comprises point first driving fixture block and second being located at rotating disk both sides and drives fixture block, be provided with the first cam in described first driving fixture block, the rotating shaft vertical rotating of described first cam is connected in the first driving fixture block; Be provided with the second cam in described second driving fixture block, the rotating shaft vertical rotating of described second cam is connected in the second driving fixture block; Described first drives fixture block and second to drive between fixture block is fixed with push pedal, described first cam is provided with the first horizontal backing pin, described first horizontal backing pin stretches out the horizontal concrete chute of the first driving fixture block, described first drives fixture block to be provided with the first fixing pin, is provided with spring between described first fixing pin and the first horizontal backing pin; Described second cam is provided with the second horizontal backing pin, and described second horizontal backing pin stretches out the horizontal concrete chute of the second driving fixture block, and described second drives fixture block to be provided with the second fixing pin, is provided with spring between described second fixing pin and the second horizontal backing pin.
When adopting technique scheme, promote push pedal, driven by push pedal and drive fixture block motion.On the one hand, drive fixture block also horizontal motion, on the other hand, cam in driving fixture block is around axis of rotation, until horizontal backing pin is arranged in chute lean on side into push pedal campaign, the flange of cam is contacted with rotating disk, makes cam drive dial movement together with driving fixture block, then exported by the live axle on rotating disk.Reverse promotion push pedal, the horizontal backing pin of cam rotates in horizontal concrete chute, makes contacting of cam disengages and rotating disk, therefore, oppositely promotes push pedal not by cam driven turntable rotation, therefore, does not have driver output.The present invention achieves the unidirectional gap transmission of output shaft by cam structure.
Further, the rotating shaft of described first cam is connected by linking springs with between the rotating shaft of the second cam.
Further, described first horizontal backing pin and the first fixing pin are located in the same horizontal plane, and described second horizontal backing pin and the second fixing pin are located in the same horizontal plane.
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 friction type cam one-way turning mechanism embodiment of the present invention.
Embodiment
As shown in Figure 1, friction type cam one-way turning mechanism of the present invention, comprise bearing, bearing rotates and is provided with a rotating disk 1, on rotating disk 1, key is connected with output shaft 11, bearing slidably connects the driving fixture block driving rotating disk 1, drives fixture block to comprise point first driving fixture block 2 and second being located at rotating disk 1 both sides and drives fixture block 3, first drives the rotating shaft vertical rotating being provided with the first cam 21, first cam 21 in fixture block 2 to be connected in the first driving fixture block 2; Second drives the rotating shaft vertical rotating being provided with the second cam 31, second cam 31 in fixture block 3 to be connected in the second driving fixture block 3; Push pedal 4 is fixed with between first driving fixture block 2 and the second driving fixture block 3, first cam 21 is provided with the first horizontal backing pin 22, first horizontal backing pin 22 stretches out the horizontal concrete chute of the first driving fixture block 2, first drives fixture block 2 to be provided with between the first fixing pin 23, first fixing pin 23 and the first horizontal backing pin 22 is provided with spring 24; Second cam 31 is provided with the second horizontal backing pin, and the second horizontal backing pin stretches out the horizontal concrete chute of the second driving fixture block 3, and second drives fixture block 3 to be provided with the second fixing pin, is provided with spring between the second fixing pin and the second horizontal backing pin.The rotating shaft of the first cam 21 is connected by linking springs 5 with between the rotating shaft of the second cam 31.First horizontal backing pin 22 and the first fixing pin 23 are located in the same horizontal plane, and the second horizontal backing pin and the second fixing pin are located in the same horizontal plane.
In the present invention, promote push pedal 4, driven by push pedal 4 and drive fixture block motion.On the one hand, drive fixture block also horizontal motion, on the other hand, cam in driving fixture block is around axis of rotation, until horizontal backing pin is arranged in chute lean on the side of moving into push pedal 4, the flange of cam is contacted with rotating disk 1, makes cam drive rotating disk 1 to move together with driving fixture block, then exported by the live axle on rotating disk 1.Reverse promotion push pedal 4, the horizontal backing pin of cam rotates in horizontal concrete chute, makes contacting of cam disengages and rotating disk 1, therefore, oppositely promotes push pedal 4 and does not rotate by cam driven rotating disk 1, therefore, do not have driver output.The present invention achieves the unidirectional gap transmission of output shaft by cam structure.
Above is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
