Abstract
The utility model discloses a work piece clamping device, in particular to a chuck-type centering clamping device which comprises a chuck body, and is characterized in that supports are uniformly distributed on the circumference on the chuck body; each support is shafted with a pressure claw; the inner side of the chuck body is provided with a press pin shaft which is propped against each press claw in the radial direction, and the inner end of the press in shaft is propped against the conical surface of a conical pin shaft in the inner hole of the chuck body; a pin bush which is supported by a spring is arranged between the press claw and the chuck body; and an elastic positioning plate is fixed on the end surface of the chuck body. Compared with the prior art, the chuck-type centering clamping device can automatically center a work piece with the elastic positioning plate, is not affected by artificial factors, has no work piece positioning gap and high precision, firmly and reliably presses with the press claws, has simple overall structure, reduces the tooling time of the work piece, and reduces the processing cost of the work piece.
Description
Technical field
The utility model relates to a kind of clamping device of workpiece, particularly a kind of chuck mode centering and clamping apparatus.
Background technology
Workpiece needs clamping device and clamps in machined, existing the termination is plate-like and has the part of circular ring structure to clamp utilize chuck mechanism to clamp more, existing clamp mechanism has workpiece and locatees the gap, centering precision is not high, influence machining accuracy, self-locking performance is poor.
Summary of the invention
The purpose of this utility model provides a kind of do not have location gap, centering precision height, self-locking performance is strong, clamping is solid and reliable, simple in structure chuck mode centering and clamping apparatus, overcomes the deficiencies in the prior art.
Chuck mode centering and clamping apparatus of the present utility model, comprise chuck body 8, it is characterized in that: the equally distributed support 11 of circumference is arranged on the chuck body 8, axle is connected with paw 1 on each support 11, radially be provided with the pad axle 6 that leans mutually with each paw 1 in chuck body 8 inboards, the inner termination of pad axle 6 leans mutually with the conical surface of the taper pin axle 7 that is positioned at chuck body 8 endoporus places; Be provided with spring-supported guide 4 between paw 1 and the chuck body 8; On the end face of chuck body 8, be fixed with elasticity positioning disk 2.
Chuck mode centering and clamping apparatus of the present utility model, wherein said elasticity positioning disk 2 is in the form of annular discs, is connected by bolting between its base plate and the chuck body 8, is connected with the distortion ring body with base plate, is processed with longitudinal opening 12 on the distortion ring body.
Chuck mode centering and clamping apparatus of the present utility model, compared with prior art can utilize elasticity positioning disk 2 automatically workpiece to be felt relieved, there is not artificial factor, gap, no workpiece location, the precision height, it is solid and reliable to utilize paw 1 to compress, and overall structure is simple, reduce the frock time of workpiece, reduced the processing cost of workpiece.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1: 8 is chuck body, is evenly distributed with three supports 11 that are integrative-structure with chuck body 8 on the circumference of the side of chuck body 8, and each support 11 is rotatably connected to paw 1 by bearing pin 3.Radially be processed with the hole relative with each paw 1 on chuck body 8, be equipped with in the hole with respect to chuck body 8 pad axle 6 movably radially, the outboard end crown of pad axle 6 leans against an end of paw 1.The inner termination of pad axle 6 leans on the conical surface of taper pin axle 7, and taper pin axle 7 is positioned at the centre bore of chuck body 8.Guide 4 is equipped with in the inboard on chuck body 8, and the external end head of guide 4 leans on paw 1, and it leans some the both sides that a little lay respectively at bearing pin 3 that lean with pad axle 6 and paw 1.Between the inboard of guide 4 and chuck body 8, be provided with spring 5.On the end face of chuck body 8, coil 2 with the flexible position of bolting, elasticity positioning disk 2 is in the form of annular discs, be connected by bolting between its base plate and the chuck body 8, be connected with the distortion ring body, on the distortion ring body, be processed with equally distributed six longitudinal openings 12 of circumference with base plate.The termination of taper pin axle 7 push rod 9 that has been threaded joins by push rod 9 and axial drive means (as hydraulic cylinder) during installation.
The course of work is as follows: 13 is workpiece, earlier will be in the Shape-changeable ring body outside of elasticity positioning disk 2 with the left end headgear of workpiece 13, make its self-centering by distortion ring body radial support workpiece 13, utilize drive unit promotion push rod 9, taper pin axle 7 to move again, the conical surface on the taper pin axle 7 leans pad axle 6 and moves laterally, an end that is leaned paw 1 by pad axle 6 again makes paw 1 rotate with respect to chuck body 8, the other end of paw 1 is pressed on the step surface of workpiece 13, spring 5 is compressed simultaneously, guide 4 moves to the inside, and this moment, the location compressed workpiece 13.Promote push rod 9, taper pin axle 7 as drive unit and oppositely move, rotates round about at the effect lower pressing claw 1 of spring 5,6 withdrawals of pad axle, releasing is to the clamping of workpiece 13.
