Abstract
The invention discloses an internal elastic clamping mechanism which includes a support. The support is equipped with an elastic sleeve which includes a bottom base and a sleeve, and the bottom base is a discoid shape and is fixed on the support through screws. The sleeve is perpendicularly placed on the sleeve, and the outer wall of the sleeve and the upper end surface of the bottom base form a workpiece clamping surface. A sealing block is fixed in the sleeve, and the sealing block, the bottom base and the sleeve together form a sealed chamber. The sealed chamber is equipped with liquid plastic, and the sealed block is equipped with an adjusting screw for squeezing the liquid plastic. By rotating the adjusting screw, the adjusting screw squeezes the liquid plastic, so that the liquid plastic can exert pressure to the walls of the chamber. Because the outer wall of the chamber is a sleeve, the sleeve deforms outward along the radial direction under the pressure of liquid plastic, thus making the workpiece placed on the bottom base and the sleeve be clamped.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work, be specifically related to a kind of inner elastomeric clamp system.
Background technology
Fixture adds to be used for rapid fastenings man-hour, makes lathe, cutter, part keep the process unit of correct relative position.Frock clamp is the indispensable parts of machining, machine tool technology at a high speed, efficient, precision, compound, intelligence, environmental protection future development drive under, clamp technology is just towards high-precision, efficient, module, combination, general, economic future development.Jig, is conducive to the machining accuracy, the stabilized product quality that ensure part; Be conducive to raising labour productivity and reducing costs; Be conducive to improving workman's working condition, ensure safety in production; Be conducive to enlarger bed process scope, realize " a tractor serves several purposes ".Fixture is usually by compositions such as setting element (determining the tram of part in fixture), clamping device, tool setting induction element (determine the relative position of cutter and part or guide tool orientation), indexing means (make part can complete the processing of several station in once mounting, have circular index device and rectilinear movement indexing means two class), Connection Element and clamp bodies (clamp base).At present, processing thin-walled part particularly thin-wall pipe time, due to the limited strength of part itself, can not clamp from outside, the damage of part can be caused from outside clamping.Consider and can not clamp from outside, elastic expansion-sleeve can only be adopted to clamp from inside.But, traditional ringfeder be by inclined-plane extruding realize tensioner, due to the angle of inclination on inclined-plane and the length on inclined-plane all limited, can not accomplish the fine setting of tensioner, clamp precision is lower.
Summary of the invention
The object of the present invention is to provide a kind of inner elastomeric clamp system, by the improvement of structure, can accomplish that tensioner is finely tuned, improve the precision of clamping.
For achieving the above object, technical scheme of the present invention is: inner elastomeric clamp system, comprises bearing, and described bearing is provided with resilient sleeve, and described resilient sleeve comprises base and sleeve, and described base is discoid, and base through screws is fixed on bearing; Described sleeve vertical is to being arranged on base, and the outer wall of described sleeve and the upper surface of base form Workpiece clamping face; Described sleeve internal fixtion has a sealing block, described sealing block and form the cavity of sealing between base and sleeve, and be provided with liquid plastics in described cavity, described sealing block is provided with the adjustment screw of extruding liquid plastics.
When adopting technique scheme, by rotating adjustment screw, by the liquid plastics in screw extrusion chamber, make liquid plastics to all directions transmission of pressure of cavity wall.Outer wall due to cavity is sleeve, and sleeve is outside evenly elastomeric radial under the extruding of liquid plastics, makes the workpiece centering clamping be placed on base and sleeve.In the present invention, owing to have employed liquid plastics as force source, liquid plastics evenly can exert a force to all directions, the fine setting that can control sleeve is expanded, ensure that the clamp precision of workpiece, and clamping force is controlled, larger chucking power can not be produced and damage thin-wall workpiece.
Further, described bearing is provided with vertical spacing screw, and the end of described stop screw contacts with liquid plastics.This setting can, by regulating the stop screw on bearing, regulate the liquid plastics preset to the pressure of sleeve, prevents from injecting too much liquid plastics and cause cannot holding workpiece.
Further, described sealing block offers link block, the end of described link block contacts with liquid plastics.This setting conveniently can inject liquid plastics by sealing lock-joint, also can play regulating action.
Further, described base is fixed on the screw on bearing is sunk screw.This setting can prevent screw place from protruding the upper surface of base, can increase effective holding area of base, saves material.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of inner elastomeric clamp system embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, inner elastomeric clamp system of the present invention, comprises bearing 1, and bearing 1 is provided with resilient sleeve, and resilient sleeve comprises base 2 and sleeve 3, and base 2 is discoid, and base 2 is fixed on bearing 1 by sunk screw; Sunk screw can prevent screw place from protruding the upper surface of base 2, can increase effective holding area of base 2, saves material.Sleeve 3 is vertically arranged on base 2, and the outer wall of sleeve 3 and the upper surface of base 2 form Workpiece clamping face; Sleeve 3 internal fixtion has a sealing block 4, sealing block 4 and form the cavity of sealing between base 2 and sleeve 3, and be provided with liquid plastics 5 in cavity, sealing block 4 is provided with the adjustment screw 6 of extruding liquid plastics.Bearing 1 is provided with vertical spacing screw 11, and the end of stop screw 11 contacts with liquid plastics 5.This setting by regulating the stop screw 11 on bearing 1, can regulate the pressure of the liquid plastics 5 pairs of sleeves 3 preset, and prevents from injecting too much liquid plastics 5 and cause cannot holding workpiece 8.Sealing block 4 offers link block 41, the end of link block 41 contacts with liquid plastics 5.This setting can inject liquid plastics 5 by sealing lock-joint is convenient, also can play regulating action.
In the present invention, by rotating adjustment screw 6, extruding plunger 7 by adjustment screw 6, the liquid plastics 5 in cavity, making liquid plastics 5 to all directions transmission of pressure of cavity wall.Outer wall due to cavity is sleeve 3, and sleeve 3 is outside evenly elastomeric radial under the extruding of liquid plastics 5, the workpiece 8 be placed on base 2 and sleeve 3 is felt relieved and clamps.In the present invention, owing to have employed liquid plastics 5 as force source, liquid plastics 5 evenly can exert a force to all directions, the fine setting that can control sleeve 3 is expanded, ensure that the clamp precision of workpiece 8, and clamping force is controlled, larger chucking power defective work piece 8 can not be produced.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
