Fixed processing object is enabled to receive the device of construction or testing.Traditional fixture, which has, to be determined guide rail, is slippingly set to and determines guide rail
On dynamic guide rail, determine guide rail and be equipped with determine jaw, move guide rail equipped with movable clamp port.Determine jaw and clamps face, movable clamp port with second
Face is clamped with parallel with the second clamping face second, therefore when dynamic guide rail drives movable clamp port relative to jaw movement is determined, is moved
Jaw and determine that the regular workpiece that both ends of the surface are parallel to each other can only be clamped between jaw.But some special workpiece such as temperature
Higher workpiece is after clamping, it is difficult to which the material returned is taken out, it is therefore desirable to mating with fixture and linkage a discharging structure.
Utility model content
The utility model solves fixture in clamping work mainly solving the technical problems that providing a kind of workpiece holding mechanism
The problem of can not being come out workpiece holding by the clamp structure of linkage after part.
In order to solve the above technical problems, the technical solution that the utility model uses is to provide a kind of workpiece holding machine
Structure, including the first cylinder, horizontal tooth bar, longitudinal rack, gear shaft, the second cylinder, clamping jaw and connecting rod；Two clamping jaws are symmetrically set
It sets；The clamping end of two clamping jaws is opposite and sets；The connecting pin of two clamping jaws is hinged on seat board；It cuts with scissors again at the middle part of every clamping jaw
It is connected to a straight connecting rod；The other end of straight connecting rod is articulated on the piston rod of the second cylinder；Second Telescopic-cylinder drives two folders
The clamping end relative motion of pawl；Second cylinder is also on fixed and seat board；The horizontal tooth bar is pushed by the first cylinder；Horizontal tooth bar
With the first gear engaged transmission on gear shaft；Second gear is set on gear shaft simultaneously；Second gear is engaged with longitudinal rack
Transmission；Longitudinal rack is vertical in the horizontal plane with horizontal tooth bar；Longitudinal rack is pushed to workpiece direction；One is connected on longitudinal rack
Push rod；The push rod is connected on seat board.
Preferably, the front end of the push rod is equipped with fixed block；The seat board is mounted on fixed block by fastener；Institute
State one guide sleeve of push rod fit on；Push rod in guide sleeve along sliding.
Preferably, the Anti-slip cover of rubber quality is set on the clamping end of the clamping jaw.
The utility model has the beneficial effects that：A kind of workpiece holding mechanism is provided, it can be to the workpiece processed on mold
Quick feeding is carried out, can be cooperated in various punching presses or drilling mold, and drive mechanism is cooperated to realize workpiece
The material returned facilitates workpiece to take out, and processing is rapidly, easy to operate, is convenient for large-scale production.
Detailed description of the invention
Fig. 1 is a kind of structure chart of workpiece holding mechanism of the utility model；
The components in the drawings are labeled as follows：1, the first cylinder；2, horizontal tooth bar；3, longitudinal rack；4, gear shaft；5,
Two cylinders；6, clamping jaw；7, connecting rod；8, push rod；9, first gear；10, second gear；11, seat board；12, fixed block.
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 drawing 1 is please referred to, the utility model embodiment includes：
A kind of workpiece holding mechanism, including the first cylinder 1, horizontal tooth bar 2, longitudinal rack 3, gear shaft 4, the second cylinder 5,
Clamping jaw 6 and connecting rod 7.Two clamping jaws 6 are symmetrical arranged, and the clamping end of two clamping jaws 6 is opposite and sets, and the connecting pin of two clamping jaws 6 is equal
It is hinged on seat board 11.The middle part of every clamping jaw 6 is hinged with a straight connecting rod 7 again, and the other end of straight connecting rod 7 is articulated with the second gas
On the piston rod of cylinder 5.The flexible clamping end relative motion for driving two clamping jaws 6 of second cylinder 5, so as to generate chucking power.
Second cylinder 5 is also fixed on seat board 11, and horizontal tooth bar 2 is pushed by the first cylinder 1.First in horizontal tooth bar 2 and gear shaft 4
The engaged transmission of gear 9 is set with second gear 10,3 engaged transmission of second gear 10 and longitudinal rack on gear shaft 4 simultaneously.It is longitudinal
Rack gear 3 is vertical in the horizontal plane with horizontal tooth bar 2, and longitudinal rack 3 is pushed to workpiece direction.A push rod is connected on longitudinal rack 3
8, push rod 8 is connected on seat board 11.The front end of push rod 8 is equipped with fixed block 12, and seat board 11 is mounted on fixed block 12 by fastener
On.8 fit on of push rod, one guide sleeve, push rod in guide sleeve along sliding.The anti-skidding of rubber quality is set on the clamping end of clamping jaw 6
Set, can big degree increase clamping stability.When work, the first cylinder pushes horizontal tooth bar movement, and horizontal tooth bar 2 will be moved
Power is transferred to gear shaft 4；Gear shaft 4 imparts power to longitudinal rack 3 by first gear 9 and second gear 10, to make
It obtains longitudinal rack 3 and pushes push rod 8.Push rod 8 has driven seat board 11 to move forward, and the second cylinder 5 is shunk, the work of the second cylinder 5
Stopper rod is linked by straight connecting rod 7 to clamping jaw 6, and according to the hinged principle of four bars, the clamping end of two clamping jaws 6 generates opposite clamping
Power.Conversely, the second cylinder 5 stretches out, clamping jaw unclamps, and the first cylinder 1 resets, and push rod 8 drives seat board 11 to retract.The clamping workpiece knot
Structure can carry out quick feeding to the workpiece processed on mold, can cooperate in various punching presses or drilling mold,
And drive mechanism is cooperated to realize the material returned of workpiece, facilitate workpiece to take out, processing is rapidly, easy to operate, is convenient for large-scale production.
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.
