Description
Technical field
The present invention relates to a kind of self-centering clamping device, particularly a kind of device being applicable to bar part Quick-clamped.
Background technology
In mechanical processing industry, the clamping mode of bar part is varied, and in current industry, self-centering's clamping mode of bar mainly contains following three kinds: mechanical type scroll chuck, hydraulic type multiple dog chuck, collet clamp.For lathe, in these three kinds of installation way, mechanical type scroll chuck is used for engine lathe, and this clamping structure is simple, highly versatile, and maintenance cost is low but production efficiency is low; Hydraulic type multiple dog chuck is used for numerically controlled lathe, this clamping highly versatile, but complex structure, and maintenance cost is high; During collet clamping is applicable to more, on the production in enormous quantities line of small pole diameter part, this clamping production efficiency is high, and structure is simple, the low but poor universality of maintenance cost, collet structure just must change corresponding collet when product bar footpath difference is larger, could meet Production requirement.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art and provide a kind of self-alignment cramping arrangement, particularly a kind of device being applicable to bar part Quick-clamped.
Technical scheme of the present invention is: a kind of self-centering fast fixture, is made up of slide cartridge, displacement disc, wedge shape jaw, cover, fore-set, return spring and trip bolt.
Described slide cartridge is provided with displacement disc installing hole, an end face of slide cartridge is provided with six screwed holes, six screwed holes are evenly arranged on the end face of slide cartridge, and another end face of slide cartridge is provided with three fore-set holes, and three fore-set holes are evenly arranged on the end face of slide cartridge.
Described displacement disc is provided with three wedge shape jaw cavity, three wedge shape jaw cavity are evenly arranged on displacement disc, rectangle chute is provided with in the bottom of each wedge shape jaw cavity, three return spring installing holes are respectively equipped with between two wedge shape jaw cavity on the end face of displacement disc, three return spring installing holes are evenly arranged between two wedge shape jaw cavity, and another end face of displacement disc is provided with three fore-set installing holes.
Described wedge shape jaw is provided with the rectangular shaped slider matched with the bottom rectangle chute of wedge shape jaw cavity.
Described cover is provided with six screw mounting holes, and six screw mounting holes are evenly arranged on cover, and cover is also provided with nine return spring installing holes, and nine return spring installing holes are corresponding with nine return spring installing holes of displacement disc.
During installation, fore-set is arranged in three fore-set installing holes on displacement disc respectively, on fore-set and displacement disc, fore-set installing hole adopts interference fit, wedge shape jaw is arranged in three wedge shape jaw cavity on displacement disc respectively, rectangular shaped slider on wedge shape jaw matches with the rectangle chute bottom the wedge shape jaw cavity on displacement disc, displacement disc is arranged on slide cartridge and is provided with in displacement disc installing hole, fore-set on displacement disc and the fore-set hole on slide cartridge adopt dynamic cooperation, cover is arranged on slide cartridge by trip bolt, return spring is arranged in the return spring installing hole of displacement disc and the return spring installing hole of cover respectively.
During work, oil cylinder promotes displacement disc by fore-set and moves forward, and force wedge shape jaw toward radial direction moving clip clamping of workpieces, shed cylinder thrust, displacement disc resets under the effect of return spring spring force, forces wedge shape jaw back to move, unclamps clamping.
The present invention compared with prior art has following features:
1, self-centering fast fixture structure provided by the invention is simple, highly versatile, and the bar diameter of clamping can differ several millimeter, even larger;
2, self-centering fast fixture adopts pneumatic or hydraulic pressure force, along with displacement disc moves forward, force three wedge shape jaws to move radially Quick-clamped bar with identical, self-centering precision is higher, clamping efficiency is high, and the size of clamping force can in regulated in wider range;
3, the relative motion contact surface of three wedge shape jaws is all plane, and wearing and tearing are relatively more even, precision will be caused to reduce phenomenon, long service life because of appearance wearing and tearing.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present invention is further described.
