Description
Technical field
The present invention relates to a kind of self-centering clamping device, particularly a kind of device that is applicable to that the bar part clamps fast.
Background technology
In mechanical processing industry, the clamping mode of bar part is varied, and self-centering's clamping mode of bar mainly contains following three kinds in the industry at present: mechanical type scroll chuck, hydraulic type multiple dog chuck, collet clamp.With the lathe is example, and in these three kinds of installation way, the mechanical type scroll chuck is used for engine lathe more, and this clamping structure is simple, highly versatile, and maintenance cost is low but production efficiency is low; The hydraulic type multiple dog chuck is used for numerically controlled lathe more, and this clamps highly versatile, but complex structure, maintenance cost is high; During collet clamps and to be applicable to more, on the production in enormous quantities line of small pole diameter part; It is high that this clamps production efficiency, and simple in structure, maintenance cost is low but versatility is poor; The collet structure just must be changed corresponding collet when the product bar directly differs big, could satisfy the production demand.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art and a kind of self-alignment cramping arrangement is provided, particularly a kind of device that is applicable to that the bar part clamps fast.
Technical scheme of the present invention is: a kind of self-centering fast fixture, form by slide cartridge, displacement disc, wedge shape jaw, cover, fore-set, return spring and trip bolt.
Described slide cartridge is provided with the displacement disc installing hole; On an end face of slide cartridge, be provided with six screwed holes; Six screwed holes are evenly arranged on the end face of slide cartridge, on another end face of slide cartridge, are 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 the slider disc; Be provided with the rectangle chute in the bottom of each wedge shape jaw cavity; Between two wedge shape jaw cavity on the end face of displacement disc, be respectively equipped with three return spring installing holes, three return spring installing holes are evenly arranged between two wedge shape jaw cavity, on another end face of displacement disc, are provided with three fore-set installing holes.
Described wedge shape jaw is provided with the rectangular shaped slider that matches 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 the cover, on cover, also is 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 installed in respectively in three fore-set installing holes on the displacement disc; Fore-set with cross Moving plate on the fore-set installing hole adopt to be full of to move and cooperate, the wedge shape jaw is installed in respectively in three wedge shape jaw cavity on the displacement disc, the rectangle chute bottom the wedge shape jaw cavity on the rectangular shaped slider on the wedge shape jaw and the displacement disc matches; Displacement disc is installed in slide cartridge and is provided with in the displacement disc installing hole; Adopt movingly in fore-set on the displacement disc and the fore-set hole on the slide cartridge, and cover is installed on the slide cartridge through trip bolt, and return spring is installed in respectively in the return spring installing hole of return spring installing hole and cover of displacement disc.
During work, oil cylinder promotes displacement disc through fore-set and moves forward, and forces the wedge shape jaw to move clamping work pieces toward radial direction, sheds cylinder thrust, and displacement disc resets under the effect of return spring spring force, forces the wedge shape jaw back to move, and unclamps clamping.
The present invention compared with prior art has following characteristics:
1, self-centering fast fixture provided by the invention is simple in structure, and highly versatile, the bar diameter of clamping can differ several millimeters, even bigger;
2, the self-centering fast fixture adopts the pneumatic or hydraulic pressure application of force; Along with displacement disc moves forward, force three wedge shape jaws with the identical quick clamping bar that moves radially, the self-centering precision is higher; Clamping efficient is high, and the size of clamping force can be in regulated in wider range;
3, the relative motion contact-making surface of three wedge shape jaws all is the plane, and it is more even to wear and tear, and can not cause precision to reduce phenomenon, long service life because wearing and tearing occurring.
Below in conjunction with the accompanying drawing and the specific embodiment detailed structure of the present invention is further described.
