Abstract
The invention discloses an automatic centering and clamping device, which comprises a cylindrical mandrel and a cylindrical expansion mould. One end of the mandrel is fixed onto a chuck, the expansion mould is sleeved on the mandrel, a cavity with an annular section is arranged inside the expansion mould, an air inlet hole is arranged on one side of the expansion mould positioned on the chuck and is communicated with the air inlet hole, an air inlet pipe is connected outside the air inlet hole, and a valve is arranged on an air inlet pipe. The automatic centering and clamping device is used for clamping and fixedly machining a workpiece, the operation is extremely convenient, the labor intensity of operators is reduced, and workpiece clamping efficiency and workpiece machining precision are improved.
Description
Technical field
The present invention relates to a kind of servicing unit of machine components processing, especially a kind of self-alignment cramping arrangement of sleeve shaped thin-wall workpiece belongs to machining servicing unit technical field.
Background technology
In machining, for the cylindrical workpiece of some thin-walleds, workpiece deformation during for fear of the chuck clamping is being to put a sleeve to refill to clip on the chuck and process in the workpiece outside generally.Though solved the problem on deformation of workpiece,, behind the clamping centering of workpiece inaccurate, the workpiece accuracy that causes processing is very low, scrappage is high.For this reason, the people in the industry has made a lot of effort, and for example one Chinese patent application number is 201110286659.4; Name is called a kind of patent of invention of self-centering fixture; Disclose a kind of anchor clamps that can self centering fixed cover tubular workpiece, it is on a taper mandrel that is fixed on the chuck, and an expansion set is set; And the adjusting nut through the expansion set tail end, control the expansion and the contraction of expansion set.But when it used, workpiece must be positioned on the mandrel side near chuck, and workpiece can not cover adjusting nut, otherwise had turned with regard to bad, like this end face of workpiece process not too convenient; And when adjusting nut rotated, the mid portion of expansion set at first expanded; Cause between workpiece and the expansion set inwall, one section is to fit to fix in the middle of having only, and both sides are all vacant; The clamping dynamics is not enough, is easy to cause between workpiece and the expansion set rotate, and influences the processing of workpiece; In addition, the clamping of workpiece is controlled through the hand rotation nut, has increased labor intensity of operating personnel, operates more loaded down with trivial details.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of convenient mounting and clamping, processing work is easy, self-alignment cramping arrangement easy and simple to handle.
Technical solution of the present invention is achieved in that a kind of self-alignment cramping arrangement, comprises mandrel and bloated carcass; Said mandrel is a cylinder, and an end of mandrel is fixed on the chuck; Said bloated carcass is a cylindrical shape, and bloated carcass sleeve is on mandrel; The inside of said bloated carcass has the cavity that the cross section is an annular, and is positioned on the bloated carcass on the side of chuck and has an air admission hole; Said air admission hole communicates with cavity, and the outside of air admission hole connects air inlet pipe; Said air inlet pipe is provided with valve.
Preferably, the madial wall of said bloated carcass sticks on the mandrel.
Preferably, said mandrel is the notch cuttype cylinder, and is fixed on the diameter of the diameter of chuck one end greater than the other end on the mandrel.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Self-alignment cramping arrangement of the present invention; Through air inlet pipe and air admission hole gas is charged in the carcass that expands; Top tight workpiece after the carcass that expands expands is realized the self-centering of workpiece, and the clamping of workpiece is very easy; The valve that only need control well on the air inlet pipe gets final product, and greatly reduces labor intensity of operating personnel; And the cavity cross section of carcass is an annular owing to expand, and after the inflation, the expansion of the carcass that expands is even, has guaranteed the machining accuracy of workpiece.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing l is a self-alignment cramping arrangement of the present invention structural representation when using;
Wherein: 1, chuck; 2, air inlet pipe; 3, valve; 4, air admission hole; 5, workpiece; 6, bloated carcass; 7, top; 8, cavity; 9, mandrel.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of self-alignment cramping arrangement of the present invention, comprises mandrel 9 and bloated carcass 6; Said mandrel 9 is a cylinder, and an end of mandrel 9 is fixed on the chuck 1; Said bloated carcass 6 is a cylindrical shape, and bloated carcass 6 is enclosed within on the mandrel 9; The madial wall of said bloated carcass 6 sticks on the mandrel 9; The inside of said bloated carcass 6 has the cavity 8 that the cross section is an annular, and is positioned on the bloated carcass 6 on the side of chuck 1 and has an air admission hole 4; Said air admission hole 4 communicates with cavity 8, and the outside of air admission hole 4 connects air inlet pipe 2; Said air inlet pipe 2 is provided with valve 3; Said mandrel 9 is the notch cuttype cylinder, and is fixed on the diameter of the diameter of chuck 1 one ends greater than the other end on the mandrel 9.
During use, workpiece 5 is enclosed within on the carcass 6 that expands, loads onto air inlet pipe 2; Open valve 3, to inflation in the cavity 8 of the carcass 6 that expands, when treating that workpiece 5 is held out against fully; Valve-off 3 takes off air inlet pipe 2, with the bigger diameter end clamping of mandrel 9 on chuck 1; The other end of mandrel 9 holds out against with top 7, can process workpiece 5.Easy to operate, reduced labor intensity of operating personnel, improved the machining accuracy of clamping workpiece efficient and workpiece.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
