Abstract
The utility model relates to an automatic centering clamping device, which comprises a mandrel and a tire expanding body, wherein the mandrel is a cylinder, in addition, one end of the mandrel is fixedly arranged on a chuck, the tire expanding body is in a round tube shape and is sheathed on the mandrel, a cavity with the annular cross section is arranged inside the tire expanding body, in addition, an air inlet hole is arranged on the tire expanding body positioned at one side of the chuck and is communicated with the cavity, the outside of the air inlet hole is connected with an air inlet pipe, and a valve is arranged on the air inlet pipe. When the automatic centering clamping device is adopted, the clamping, fixing and processing can be carried out on workpieces, the operation is very convenient, the work intensity of operators is reduced, and the workpiece clamping efficiency and the workpiece processing precision are improved.
Description
Technical field
The utility model relates to a kind of servicing unit of machine components processing, and 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 conical 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 axle 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
The utility model purpose is for the deficiency that overcomes prior art a kind of convenient mounting and clamping to be provided, and processing work is easy, self-alignment cramping arrangement easy and simple to handle.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of self-alignment cramping arrangement comprises axle and bloated carcass; Said axle is a cylinder, and an end of axle is fixed on the chuck; Said bloated carcass is a cylindrical shape, and bloated carcass sleeve is on axle; 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 axle.
Preferably, said axle 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 axle.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of self-alignment cramping arrangement of the utility model scheme; 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 the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of the self-alignment cramping arrangement of the utility model 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, axle.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
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 axle 9 on chuck 1; The other end of axle 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.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
