Abstract
The utility model discloses a kind of self-centering clamping device, include workbench, it is characterized in that: the wedge seat that this device includes cylinder and is arranged on described cylinder piston rod upper end and the one group of claw holder be arranged on above described wedge seat, and claw is set on described claw holder.The beneficial effects of the utility model are: after flange workpiece is clamped by claw, and namely its center is determined.Human assistance time during a large amount of saving flange clamping and positioning, the flange of same diameter, position only need adjust once.Reduce production cost.Improve operating efficiency, simple and practical.
Description
Technical field
The utility model relates to large ring field of machining, especially relate to a kind of Self-centering device during ring boring.
Background technology
At present in numerical control plane drill press is produced, when flange, pipe part plane are holed, need flange, pipe part to fix on the table, usual lathe bed is arranged some T type grooves, compress flatbed manner fixation workpiece by frock.Be drilled fiducials with the photoelectric edge-searching device determination workpiece center of circle, then hole.During processing work, because each part workpiece to be processed clamping position is different, cause adding machining benchmark in man-hour position different, all need the processing center of circle determining this processing work with photoelectric edge-searching device before each processing, the self centering function of workpiece can not be realized, workpiece centre and processing work platform center cannot be coincide automatically, troublesome poeration, leading time is longer, affects the operating efficiency of whole drilling operating, restriction manufacturing schedule.This is the deficiencies in the prior art parts.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, easy to operate, can realize workpiece self-centering function, improve the drill press workpiece self-centering clamping device of working (machining) efficiency.The problem of centering, location is needed, a kind of Self-centering device of energy Quick self-centering when solving annular element boring.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of self-centering clamping device, include workbench, it is characterized in that: the wedge seat that this device includes cylinder and is arranged on described cylinder piston rod upper end and the one group of claw holder be arranged on above described wedge seat, and claw is set on described claw holder, bottom described claw holder, line slideway is set.Line slideway is fixing on the table, is used for supporting and guided-moving parts, does linear reciprocating motion by given direction.After flange workpiece is clamped by claw, namely its center is determined.Human assistance time during a large amount of saving flange clamping and positioning, the flange of same diameter, position only need adjust once.
Further improvement of the utility model has, and described wedge seat arranges 3 wedges and along the circumferential direction uniform setting.Three wedge coaxial design, from the bottom up gradually near center line, put into claw annular workpieces, and without the need to adjustment, cylinder and workbench are fixed, and control wedge seat moved self-centering, clamping by cylinder.
Further improvement of the utility model also has, and described one group of claw holder is set to 3 and along the circumferential direction uniform setting, and the T-shaped slider I of its end is placed in described wedge.
Further improvement of the utility model also has, on described claw holder top, T-slot is set, bottom described claw, arrange groove, T-shaped slide block II is placed in the capable groove of T on described claw holder and the groove on described claw, and described claw and described T-shaped slide block II are bolted.
The structure described is not had to belong to prior art in description.
The beneficial effect of this programme can be learnt according to describing of such scheme, a kind of self-centering clamping device, include workbench, it is characterized in that: the wedge seat that this device includes cylinder and is arranged on described cylinder piston rod upper end and the one group of claw holder be arranged on above described wedge seat, and claw is set on described claw holder.The beneficial effects of the utility model are: after flange workpiece is clamped by claw, and namely its center is determined.Human assistance time during a large amount of saving flange clamping and positioning, the flange of same diameter, position only need adjust once.Reduce production cost.Improve operating efficiency, simple and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the A partial enlargement structural representation of Fig. 1, and Fig. 3 is the B partial enlargement structural representation of Fig. 1.In figure: 1 is cylinder, 2 is wedge seats, and 3 is line slideways, and 4 is claw holders, and 5 is claws, and 6 is wedges, and 7 is T-shaped slider I, and 8 is piston rods, and 9 is T-shaped slide blocks II.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Can be found out by accompanying drawing, a kind of self-centering clamping device, include workbench, it is characterized in that: the wedge seat 2 that this device includes cylinder 1 and is arranged on described cylinder piston rod 8 upper end and the one group of claw holder 4 be arranged on above described wedge seat 2, and claw 5 is set on described claw holder 4, bottom described claw holder 4, line slideway 3 is set.Described wedge seat 2 arranges 3 wedges 6 and along the circumferential direction uniform setting.Described one group of claw holder 4 is set to 3 and along the circumferential direction uniform setting, and the T-shaped slider I 7 of its end is placed in described wedge 6.Arrange T-slot on described claw holder 4 top, bottom described claw 5, arrange groove, T-shaped slide block II 9 is placed in the T-slot on described claw holder 4 and the groove on described claw 5, and described claw 5 is bolted with described T-shaped slide block II 9.
Operation principle: wedge-type three-jaw Self-centering device is made up of claw, claw holder, wedge, line slideway, cylinder, magnetic valve etc.Three groups of claw holders along the circumferential direction wait and all distribute, and drag clamping or unclamp by cylinder.Claw moves position on claw holder, can adapt to the flange of different-diameter.After flange workpiece is clamped by claw, namely its center is determined.Human assistance time during a large amount of saving flange clamping and positioning.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belongs to protection domain of the present utility model.
