Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Attached Fig. 1 and 2 is please referred to, the utility model embodiment includes:
A kind of workpiece holding structure, including guide rod 1, sliding seat board 2, driving wheel 3, sheave 4, collet 5, pull rod 6 and torsion
Axis 7.Guide rod 1, driving wheel 3, sheave 4 provide chucking power, and the collet 5 and torsional axis 7 that are set on the support 8 are by chucking power
It timely responds to away.
Two sliding seat boards 2 are set on guide rod 1, are slided and are equipped with fixed fixing threaded hole on seat board 2.The two of guide rod 1
Side surface is equipped with guide groove, and the tooth head of sliding 2 bottom of seat board is caught in guide groove.The linear slide in the horizontal direction of guide rod 1 is not
It will receive the influence of sliding seat board 2, even sliding seat board 2 is fixed in other structures, will not be because of docking structure
And hinder linear motion.A toothed rack 9 is fixed in the lower surface that against guide rod 1, and flank of tooth transmission is used as most stable of drive mechanism,
Transmission variation and fit system are easy to control.In one end of guide rod 1, setting is equipped with the sliding slot 10 perpendicular to 1 glide direction of guide rod,
Sliding slot 10 is vertically arranged, and the side of guide rod 1 is provided with motor 11, is matched between motor 11 and sliding slot 10 by crank 12
It closes, crank 12 is parallel with guide rod 1.The output end and guide rod 1 of motor 11 are located at same level height, move when the transmission of motor 11 generates
When power, centre of motion deviation will not be led to the problem of.The output end set of motor 11 is filled to one end of crank 12, crank 12 it is another
End is then cooperated in sliding slot 10 by the socket cap of protrusion.When motor 11 drives crank rotation, crank 12 just does turning for circular ring shape
Dynamic, when only the length of crank 12 is the half of 10 length of sliding slot, crank 12 could push sliding slot 10, to push entire guide rod
1 moves in a straight line.
3 engaged transmission of rack gear 9 and driving wheel, is additionally provided with the disk 13 for protruding from end face on the same side end face of driving wheel 3
With round bar 14.It is equipped with sheave 4 in the downside of driving wheel 3, along being arranged radially through slot 15 on sheave 4.In 15 two sides of through slot point
It does not set there are two arc-shaped curved surface 16, driving wheel 3 is rotatably assorted the rotation of sheave 4, and arc-shaped curved surface 16 matches intermittence with disk 13
It closes, round bar 14 and the intermittent cooperation of through slot 15.The diameter of disk 13 is less than the diameter of driving wheel 3, and the setting of round bar 14 is being driven
The end face edge of wheel 3.Centered on the center of circle of driving wheel 3, the two is opposite and sets for disk 13 and round bar 14.When driving wheel 3 is in tooth
When producing rotation under the cooperation of item 9, driving wheel 3 occurs the complete revolution between counter clockwise direction clockwise or not exclusively returns
Turn, it is at the uniform velocity and controlled for rotating, and unstability is as when stress increases or retard motion, resistance can be directly transferred to
Force piece, and cause to damage firmly to force piece and transmission are whole.But cooperate sheave 4 on driving wheel 3, pass through disk 13 and arc
The cooperation of shape curved surface 16, resistance can be only operated on driving wheel 3, will not cause to damage to other structures.And with round bar
14 with the cooperation of through slot 15, the output rotation of sheave 4 be it is instantaneous, will not be hindered, transmission is rapider.
Four support ends 17 stretched out straight down are set on supporter 8, and collet 5 is mounted on support end 17.Collet 5 is in Z
Font structure is equipped with shaft 18 at the middle part of collet 5, and the both ends of shaft 18 pass through bearing part respectively and install to the branch of its two sides
It supports on end 17.One end of collet 5 is clamping end, piece connecting rod 19 of the other end.When opposite rotation occurs for two collets 5
When, the clamping end of two collets 5 moves synchronously, and two collets 5 clamp object when moving toward one another, and object is similarly then decontroled when counter motion
Body.Torsional axis 7 is set on supporter 8, and torsional axis 7 is arranged between two connecting rods 19, and torsional axis 7 is coaxially fixed on sheave 4.
The endless full circle swinging of sheave 4 is that torsional axis 7 provides the movement of instantaneous needle and both direction counterclockwise, so that torsional axis 7 obtains
The aid power of collet.
Opposite otic placode there are two setting on the rotary surface of torsional axis 7, two otic placodes are using axis as symmetrical centre.Two companies
Bar 19 is hinged on the otic placode of corresponding side by pull rod 6 respectively, and one end of connecting rod 19 is soldered on collet 5, other end hinge
It is connected to one end of pull rod 6, and the other end of pull rod 6 is hinged on otic placode.When torsional axis 7 is rotated under power, otic placode
Circumferential movement is just produced, the otic placode of two sides will pull pull rod 6 simultaneously, and active force is transferred to connecting rod 19 by pull rod 6, even
Bar 19 drives collet 5 to rotate around its shaft 18.External force is excessive in order to prevent and rotates two problems resetted, in torsional axis
Torsional spring 20 is further sleeved on 7.One end of torsional spring 20 is fixed on torsional axis 7, and the other end is fixed on supporter 8, and elasticity is turned round
Strength buffering can be provided and reset two effects by turning power.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
