Abstract
A multistage equal deformation elastic positioning and clamping device is used for automatically positioning and clamping workpieces. A multistage tooth-shaped elastic clamping jacket is fixed on a positioning base, and a multistage tooth-shaped pull rod mandrel is arranged in an inner hole of the multistage tooth-shaped elastic clamping jacket. The positioning base is arranged on a clamp body. A piston rod of a magnetic induction type oil cylinder is connected with the multistage tooth-shaped pull rod mandrel through an internal thread of the piston and an external thread of the multistage tooth-shaped pull rod mandrel. The magnetic induction type oil cylinder is mounted in the clamp body, and a dustproof ring is arranged on the top of the multistage tooth-shaped elastic clamping jacket. The tooth-shaped structure of the multistage tooth-shaped pull rod mandrel and the multistage tooth-shaped elastic clamping jacket is composed a horizontal plane which is symmetrically distributed along the center line of the tooth-shaped structure and an oblique plane which forms an angle of 10-30 degree with the horizontal plane. The multistage equal deformation elastic positioning and clamping device has the advantages of being high in positioning and clamping precision, easy to operate, stable and reliable in performance, high in anti-interference performance and universality and the like.
Description
Technical field
The present invention relates to mechanical equipment technical field, specifically a kind of automatic positioning clamping apparatus for processing 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 the overproof and machining deformation of the axiality of part, perpendicularity from being the difficult problem of mechanical processing industry.Existing solution adopts Internal hole positioning spring Bloated tight cartridge, reach the object of location Clamp blocks, but this positioning collet exists following drawback:
1, the collet internal taper hole with 10 degree of taperings coordinates with mandrel, when mandrel by oil cylinder pull to rear mobile time, 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 then can not contact completely with 10 mandrels of boring of being outside one's consideration, and only has local in 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 is very large gap between collet internal taper hole and mandrel, collet cylindrical does not linearly evenly swell, part to be processed is made not to 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, with the perpendicularity of end face, and the position degree of respective aperture system can not meet the technological requirement of drawing, the instability of the serious overproof and quality of the craft precision causing processing rear part, great economic loss and the wasting of resources is caused to enterprise.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of multistage positioning clamping apparatus such as elastomeric deformable such as grade, 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 invention 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 carried, 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 along the symmetrical horizontal plane of its center line with become 10 degree of-30 inclined-plane spent to be formed with horizontal plane.
Multistage profile of tooth pull bar mandrel to be moved down by the pulling force of oil cylinder and forces the outside distending of multistage profile of tooth elastic jacket by the present invention, realizes accurate location clamping object automatically.
The present invention compared with prior art, has the following advantages:
1, clamping accuracy is located high.All connected by matched in clearance between each parts of the present invention, multistage profile of tooth pull bar mandrel and multistage profile of tooth elastic jacket all adopt equidistant angularly tooth-shape structure, in Long-Time Service process, 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 automatically make up elimination gap error, still keep very high location clamping accuracy.
2, simple to operate, stable performance.The present invention carrys out hydraulic control oil cylinder by electric system, only needs button press lightly, can realize automatic location and the clamping of workpiece.Due to employing is hydraulic drive, and stable and reliable for performance, practicality is high.
3, strong anti-interference performance.The present invention adopts and is arranged in clamp body by holds magnetic induction type oil cylinder, and the top of multistage profile of tooth elastic jacket is with the dustproof design of dust ring, can not because of the iron filings produced when machining, dust, cutting fluid and reduce its precision and hinder location pinching action.
4, highly versatile, can reduce the labour intensity of designer.Structure of the present invention is simple, and flexibility is strong, can design, only need the length dimension suitably lengthening or shorten multistage profile of tooth pull bar mandrel to realize, can be widely used on nipper according to part to be processed size.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Detailed description of the invention
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 along the symmetrical horizontal plane of its center line with become 10 degree of-30 inclined-plane spent to be formed with horizontal plane, 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 carried, and holds magnetic induction type oil cylinder 7 is arranged in clamp body 5.
Operation principle of the present invention:
When 1, unclamping, the piston rod 6 of holds magnetic induction type oil cylinder 7 protrudes upward, and is released by multistage profile of tooth pull bar mandrel 1, and multistage profile of tooth pull bar mandrel 1 is separated with multistage profile of tooth elastic jacket 2, and multistage profile of tooth elastic jacket 2, in nature releasing orientation, puts into workpiece 3.
2, during 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 combines closely with the teeth on multistage profile of tooth elastic jacket 2, under the effect of hydraulic coupling, multistage profile of tooth elastic jacket 2 grade is forced to be out of shape evenly outwards distending, to reach the object that clamping located automatically by workpiece 3.
