Description
Technical field
The utility model relates to mechanical equipment technical field, specifically a kind of for processing the automatic positioning clamping apparatus of the parts such as inside and outside circle part, gear class, Shell-Class, casing class.
Background technology
At present, for Shell-Class and the gear part of processing inside and outside circle with Internal hole positioning, how to prevent that the overproof and machining deformation of axiality, the perpendicularity of part from being a difficult problem for mechanical processing industry.Existing solution is to adopt Internal hole positioning spring Bloated tight cartridge, reach the object of location clamping part, but this positioning collet exists following drawback:
1, coordinate with mandrel with the collet internal taper hole of 10 degree taperings, when mandrel is pulled to rear when mobile by oil cylinder, collet distortion increases, its internal taper hole is greater than 10 degree, and the tapering of mandrel remains 10 degree, collet internal taper hole tapering with 10 be outside one's consideration cone mandrels can not contact completely, only have part to be linear bonding state, and most of conical surface exists very large gap, collet internal taper hole and outer cone mandrel can not be fitted completely.
2, owing to there being very large gap between collet internal taper hole and mandrel, collet cylindrical does not linearly evenly swell, make part to be processed can not be accurately positioned clamping, and clamping force is also inadequate, in process, part easily produces vibration, damage equipment and cutter, make the axiality between technological datum endoporus and inside and outside circle, cylindricity, beat, perpendicularity with end face, and the position degree of respective aperture system can not meet the technological requirement of drawing, cause processing the unstable of the serious overproof and quality of the craft precision of rear part, cause great economic loss and the wasting of resources to enterprise.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of multistage distortion elasticity positioning clamping apparatus that waits, and improves the location chuck(ing) capacity of part to be processed and the object of craft precision to reach.
For achieving the above object, multistage profile of tooth elastic jacket of the present utility model is fixed on positioning pedestal, and multistage profile of tooth pull bar mandrel is located in the endoporus of multistage profile of tooth elastic jacket; Positioning pedestal is contained on clamp body; The piston rod of holds magnetic induction type oil cylinder is connected with the external screw thread of multistage profile of tooth pull bar mandrel by the internal thread carrying, and holds magnetic induction type oil cylinder is arranged in clamp body.
The top of described multistage profile of tooth elastic jacket is with dust ring.
The tooth-shape structure of described multistage profile of tooth pull bar mandrel, multistage profile of tooth elastic jacket is by being formed with the inclined-plane that becomes 10 degree-30 degree with horizontal plane along the symmetrical horizontal plane of its center line.
The utility model is moved down multistage profile of tooth pull bar mandrel to force the outside distending of multistage profile of tooth elastic jacket by the pulling force of oil cylinder, realizes accurate location automatically and clamps object.
The utility model compared with prior art, has the following advantages:
1, location clamping accuracy is high.Between each parts of the present utility model, all connect by matched in clearance, multistage profile of tooth pull bar mandrel and multistage profile of tooth elastic jacket all adopt equidistant equal angles tooth-shape structure, in long-term use procedure, because suffered pulling force is balanced, the wearing and tearing each other of internal tooth and external tooth are also uniform, even if generation gap, also can make up elimination gap error automatically, still keep very high location clamping accuracy.
2, simple to operate, stable performance.The utility model is controlled hydraulic jack by electric system, only need press lightly button, can realize automatic location and the clamping of workpiece.Be hydraulic drive due to what adopt, stable and reliable for performance, practicality is high.
3, strong anti-interference performance.The utility model adopts holds magnetic induction type oil cylinder is arranged in clamp body, and the top of multistage profile of tooth elastic jacket is with the dustproof design of dust ring, can not reduce its precision and hinder location because of the iron filings that produce when the machining, dust, cutting fluid clamping action.
4, highly versatile, can reduce designer's labour intensity.The utility model is simple in structure, and flexibility is strong, can design according to part to be processed size, and the length dimension that only need to suitably lengthen or shorten multistage profile of tooth pull bar mandrel can be realized, and can be widely used on nipper.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
The specific embodiment
As shown in Figure 1, multistage profile of tooth elastic jacket 2 is fixed on positioning pedestal 4, multistage profile of tooth pull bar mandrel 1 is located in the endoporus of multistage profile of tooth elastic jacket 2, the tooth-shape structure of described multistage profile of tooth pull bar mandrel 1, multistage profile of tooth elastic jacket 2 is by being formed with the inclined-plane that becomes 10 degree-30 degree with horizontal plane along the symmetrical horizontal plane of its center line, and the top of multistage profile of tooth elastic jacket 2 is with dust ring 8; Positioning pedestal 4 is contained on clamp body 5; The piston rod 6 of holds magnetic induction type oil cylinder 7 is connected with the external screw thread of multistage profile of tooth pull bar mandrel 1 by the internal thread carrying, and holds magnetic induction type oil cylinder 7 is arranged in clamp body 5.
Operation principle of the present utility model:
1, while unclamping, the piston rod 6 of holds magnetic induction type oil cylinder 7 protrudes upward, and multistage profile of tooth pull bar mandrel 1 is released, and multistage profile of tooth pull bar mandrel 1 separates with multistage profile of tooth elastic jacket 2, and multistage profile of tooth elastic jacket 2 is nature releasing orientation, puts into workpiece 3.
2, while work, the piston rod 6 of holds magnetic induction type oil cylinder 7 retracts downwards, multistage profile of tooth pull bar mandrel 1 is retracted, oblique teeth on multistage profile of tooth pull bar mandrel 1 also move down thereupon with multistage profile of tooth elastic jacket 2 on teeth combine closely, under the effect of hydraulic coupling, force evenly outside distending such as multistage profile of tooth elastic jacket 2 distortion such as grade, to reach workpiece 3 object that location clamps automatically.
