Abstract
The utility model discloses a rapid clamping device, including cylinder block, cylinder and clamping jaw, the cylinder is installed on the cylinder block, and the piston rod of cylinder is the cavity setting, and the clamping jaw is inserted and is located in the piston rod to but clamping jaw and piston rod relative slip, the top inner wall of piston rod is equipped with interior scarf, and the top outer wall of clamping jaw is equipped with the outer scarf with interior scarf matched with. The utility model has the advantages of simple and reasonable structure, processing is convenient, the installation is swift, manufacturing cost is lower, sensitivity is higher, the clamping position effect is better.
Description
Technical field
This utility model relates to clamping device technical field, particularly to a kind of fast fixture.
Background technology
Clamping device is mainly used in workpiece is carried out clamping position, applies relatively broad, be known in automated production equipment.Clamping device common on the market at present usually occurs with the form of Pneumatic clamping jaw.The operation principle of Pneumatic clamping jaw controls jaw action mainly by the flexible of cylinder piston rod, thus realizing the clamping to workpiece or unclamping.But, existing Pneumatic clamping jaw device has the disadvantage that: first, and structure arranges complex, and each parts difficulty of processing when producing is relatively big, causes that manufacturing cost is higher, and installs relatively complicated inconvenience；Second, the linkage component between piston rod and jaw is more so that jaw action sensitivity is relatively low.
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, it is provided that one is simple and reasonable, easy to process, quick for installation, manufacturing cost is relatively low, sensitivity is higher, the good fast fixture of clamping position effect.
For achieving the above object, this utility model is by the following technical solutions:
A kind of fast fixture described in the utility model, including cylinder block, cylinder and jaw, described cylinder is installed on described cylinder block, the piston rod of described cylinder is that hollow is arranged, described jaw is inserted in described piston rod, and described jaw and described piston rod can relative sliding, the top inwall of described piston rod is provided with interior wedge surface, and the top outer wall of described jaw is provided with the outer wedge surface matched with described interior wedge surface.
Further, described jaw includes big footpath clamping sleeve and path grafting sleeve, it is provided with described outer wedge surface between described big footpath clamping sleeve and described path grafting sleeve, described path grafting sleeve activity is inserted in described piston rod, the wall of described big footpath clamping sleeve is provided with some contraction breach, and described contraction breach extends to described path grafting sleeve.
Further, the inwall of described big footpath clamping sleeve is provided with positioning step portion.
The beneficial effects of the utility model are: the fast fixture that this utility model provides, under duty, air cylinder driven piston rod moves, piston rod upper move past journey is coordinated with outer wedge surface by interior wedge surface be pushed up to jaw, drive and jaw moves, promote jaw and absorption surface to be clamped, when the upper end of jaw offsets with corresponding position-limit mechanism, jaw cannot continue upper shifting, and now piston rod still can continue under the driving of cylinder on move, piston rod is made to pass through the outer wedge surface of interior wedge surface extruding jaw, promote the upper end contraction distortion of jaw, and Workpiece clamping the most at last；When needs unclamp workpiece, piston rod moves down, and the radial forces between interior wedge surface and outer wedge surface disappears, and jaw unclamps workpiece and again falls to original position under gravity.
In sum, this utility model is by being plugged in jaw activity in piston rod, and utilizes interior wedge surface to coordinate the control realized jaw with outer wedge surface, not only easy to process, quick for installation, manufacturing cost is relatively low, and the sensitivity of jaw is higher when working, clamping position effect is better.This utility model structure arranges advantages of simple.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is the structural representation of jaw of the present utility model.
In Fig. 1 and Fig. 2:
1, cylinder block；2, cylinder；21, piston rod；3, jaw；31, big footpath clamping sleeve；311, positioning step portion；32, path grafting sleeve；33, outer wedge surface；34, breach is shunk.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
A kind of fast fixture as depicted in figs. 1 and 2, including cylinder block 1, cylinder 2 and jaw 3, cylinder 2 is installed on cylinder block 1, the piston rod 21 of cylinder 2 is arranged in hollow, jaw 3 is inserted in piston rod 21, and jaw 3 and piston rod 21 can relative sliding, the top inwall of piston rod 21 is provided with interior wedge surface, and the top outer wall of jaw 3 is provided with the outer wedge surface 33 matched with interior wedge surface.
Under duty, cylinder 2 drives and moves on piston rod 21, piston rod 21 upper move past journey is coordinated with outer wedge surface 33 by interior wedge surface be pushed up to jaw 3, drive and jaw 3 moves, promote jaw 3 and absorption surface to be clamped, when the upper end of jaw 3 offsets with corresponding position-limit mechanism, jaw 3 cannot continue upper shifting, and now piston rod 21 still can continue under the driving of cylinder 2 on move, make piston rod 21 by the outer wedge surface 33 of interior wedge surface extruding jaw 3, promote the upper end contraction distortion of jaw 3, and Workpiece clamping the most at last；When needs unclamp workpiece, piston rod 21 moves down, and the radial forces between interior wedge surface and outer wedge surface 33 disappears, and jaw 3 unclamps workpiece and again falls to original position under gravity.
As a kind of preferred implementation of the present utility model, jaw 3 includes big footpath clamping sleeve 31 and path grafting sleeve 32, it is provided with outer wedge surface 33 between big footpath clamping sleeve 31 and path grafting sleeve 32, path grafting sleeve 32 activity is inserted in piston rod 21, the wall of big footpath clamping sleeve 31 is provided with some contraction breach 34, shrinks breach 34 and extends to path grafting sleeve 32.By jaw 3 is set to tube-in-tube structure, it is possible to effectively increasing the contact area between claw and workpiece, thus further increasing clamping effect of the present utility model, stability is higher.
The inwall of big footpath clamping sleeve 31 is provided with positioning step portion 311, realizes the axial location to workpiece by positioning step portion 311, and locating effect is better.
The above is only better embodiment of the present utility model, therefore all equivalences done according to the structure described in this utility model patent claim, feature and principle change or modify, and are all included in this utility model patent claim.
