Abstract
The utility model provides an automatic pneumatic chuck, comprising a chuck body, a pedestal, pistons, compressed springs and steel balls. The automatic pneumatic chuck is characterized in that the chuck body is installed on the pedestal which is provided with a blind rivet groove; the side wall of the blind rivet groove is provided with steel ball holes; steel balls are disposed in the steel ball holes; the thickness of the side wall of the blind rivet groove is less than the diameter of the steel balls; a piston groove is formed between the outer end face of the side wall of the blind rivet groove and the chuck body; the pistons are disposed in the piston groove; compressed spring grooves are disposed in the pistons; and compressed springs in a compressed state are disposed in the compressed spring grooves. With the automatic pneumatic chuck, repeated location of the parts is not needed when parts should be moved to different machine tools and stations during a process of precision machining, and location of the parts requiring machining can be completed at a time, so that error accumulation generated by repeated location is reduced, precision of clamping location is improved and the requirements of large-scale automatic production are met.
Description
Technical field
The utility model belongs to machining and uses the clamp technology field, specifically just relates to a kind of automatic air pressure chuck that clamps usefulness for the precision component mechanical processing process.
Background technology
Chuck is to be used for the mechanical device of clamping work pieces on the lathe, utilizes moving radially of the movable jaw that is distributed on the chuck body, the machine tool accessories of Workpiece clamping and location.Chuck generally is comprised of chuck body, movable jaw and claw driving mechanism 3 parts.Chuck body diameter minimum is 65 millimeters, and maximum can reach 1500 millimeters, and there is through hole in central authorities, so that by workpiece or bar, the back has cylindrical or the short taper profile structure, directly or by ring flange and machine tool chief axis end links.Chuck usually is installed on lathe, cylindrical grinder and the internal grinder and uses, and also can cooperate with various indexing means, is used for milling machine and drilling machine.Above the chuck jaw number, can be divided into: two-jaw(ed)chuck, scroll chuck, chuck, six dog chucks and special chuck; Can be divided into from using on the power: hand chuck, air spider, oild chuck, electric chuck and mechanical chuck; Above structure, can also be divided into: hollow type and full mold.
Along with the required precision of machine components is more and more higher, also more and more higher to the positioning accuracy request of each lathe in the mechanical processing process and each manufacturing procedure.Especially the precision of positioning fixture directly affects the final precision of product especially in enormous quantities, automated production, existing location tensioning technique, workpiece is when changing, positional precision control difficulty, perhaps will spend the more time proofreaies and correct repeatedly, in enormous quantities, automated production positioning accuracy even can't guarantee.
Even take existing accurate chuck for Vehicle Processing or mill processing, running accuracy during clamping work pieces or positional precision generally all can be greater than 0.005mm, if same part must just can be finished by many lathes the man-hour that adds of the different Ministry of worker, in the conversion of workpiece between lathe and lathe, need to repeat to clamp, proofread and correct, not only time-consuming but also can't guarantee precision, more can't realize in enormous quantities, automated production.
The utility model content
The purpose of this utility model provides a kind of automatic air pressure chuck, when part need to be changed lathe and station in the Precision Machining process, do not need resetting, the disposable just part of required processing can the location be finished, reduced the deviation accumulation that resetting produces, improve the precision of clamping and positioning, adapted to the needs of mass automatic production.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of automatic air pressure chuck, comprise chuck body, base, piston, stage clip and steel ball, it is characterized in that: described chuck body is contained on the base, have the blind rivet groove on the base, have steel ball hole on the blind rivet groove sidewall, steel ball is housed in the steel ball hole, blind rivet groove sidewall thickness is less than steel ball size, blind rivet groove sidewall outer face and chuck body form piston groove, and piston is housed in the piston groove, have pressure spring slot in the piston, stage clip is housed in the pressure spring slot, and stage clip is in compressive state.
In the described blind rivet groove blind rivet is housed, blind rivet has the steel ball bit-avoiding slot at the steel ball correspondence position, and the blind rivet internal lock has screw, and screw head is equipped with pallet.
