Abstract
The invention relates to a mechanical positioning chuck, which comprises a chuck body (1) and is characterized in that a nail pulling groove (2) is arranged on the chuck body (1), a steel ball hole (3) is arranged on the side wall of the nail pulling groove (2), a steel ball (4) is arranged in the steel ball hole (3), the side wall thickness of the nail pulling groove (2) is smaller than the diameter of the steel ball (4), a lock ring groove is arranged outside the side wall of the nail pulling groove (2), a lock ring (5) is arranged in the lock ring groove, one end surface of the lock ring (5) is in contact with the steel ball (4), the other end surface of the lock ring (5) is provided with a handle (6), and the handle (6) passes through a through hole arranged on the chuck body (1) to extend out of the chuck body (1). The mechanical positioning chuck has the advantages that a mode of combining the steel ball and the lock ring is adopted, the repeated positioning of parts is not needed during machine tool and station replacement in the precise processing process, the positioning of the parts to be processed can be completed in one step, the error accumulation generated by the repeated positioning is reduced, the clamping positioning precision is improved, the mechanical positioning chuck is suitable for large-scale automatic production requirements, in addition, the structure of the whole device is simple, and the manufacture cost is low.
Description
Technical field
The invention belongs to machining and use the clamp technology field, specifically just relate to a kind of mechanical type positioning chuck that the precision component process clamps usefulness that is used for.
Background technology
Chuck is to be used for the mechanical device of clamping work pieces on the lathe, is to utilize moving radially of the movable jaw that is distributed on the chuck body, clamps workpiece and the machine tool accessories of location.Chuck generally is made up 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 through workpiece or bar; The back has cylindrical or the short taper profile structure, directly or through ring flange and machine tool chief axis end links.Chuck is installed in usually 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; From working power, can be divided into: 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 increasingly high, also increasingly high to the positioning accuracy request of each lathe in the mechanical processing process and each manufacturing procedure.Especially the precision of positioning fixture directly influences 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 to proofread and correct repeatedly, and this can't guarantee in enormous quantities, automated production positioning accuracy.Even take existing accurate chuck to be used for Vehicle Processing or to mill processing; Running accuracy during clamping work pieces or positional precision generally all can not meet processing request greater than 0.005mm, if same part must could be accomplished the man-hour that adds of the different Ministry of worker through many lathes; In the conversion of workpiece between lathe and lathe; Need 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.
Summary of the invention
The purpose of this invention is to provide a kind of mechanical type positioning chuck; In the Precision Machining process, part does not need resetting when changing lathe and station; Disposable just can the part of required processing the location accomplished; Reduce the deviation accumulation that resetting produces, improved 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 present invention designs a kind of mechanical type positioning chuck, comprises chuck body; It is characterized in that: have the blind rivet groove on the said chuck body, have steel ball hole on the blind rivet groove sidewall, steel ball 4 is housed in the steel ball hole; Blind rivet groove sidewall thickness is less than steel ball size, and blind rivet groove sidewall has gutter outward, and retainer is housed in the gutter; Retainer one end face contacts with steel ball, and handle is equipped with in the other end, and the through hole that handle passes on the chuck body reaches outside the chuck body.
In the said blind rivet groove blind rivet is housed, blind rivet has the steel ball bit-avoiding slot at the steel ball correspondence position, the blind rivet screw of having locked, and screw head is equipped with pallet.
At least 2 of said steel ball, retainer and handle quantity are evenly distributed on around the blind rivet groove.
Outstanding positioning tooth has stopper slot with the positioning tooth corresponding position on the said pallet on the said chuck body.
Beneficial effect
The mode that the present invention adopts steel ball and retainer to combine, in the Precision Machining process, part is when changing lathe and station; Do not need resetting, disposable just can the part of required processing the location accomplished, and reduce the deviation accumulation that resetting produces; Improved the precision of clamping and positioning; The needs that adapt to mass automatic production, and whole apparatus structure is simple, inexpensive.
Description of drawings
Accompanying drawing 1 is a releasing orientation structural representation of the present invention.
Accompanying drawing 2 is tension structural representations of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described further.
Shown in accompanying drawing 1, a kind of mechanical type positioning chuck comprises chuck body 1, wherein; Have blind rivet groove 2 on the said chuck body 1, have steel ball hole 3 on blind rivet groove 2 sidewalls, steel ball 4 is housed in the steel ball hole 3; Blind rivet groove 2 sidewall thickness are less than steel ball 4 diameters, and blind rivet groove 2 sidewalls have gutter outward, and retainer 5 is housed in the gutter; Retainer 5 one end faces contact with steel ball 4, and handle 6 is equipped with in the other end, and the through hole that handle 6 passes on the chuck body 1 reaches outside the chuck body 1.
In the said blind rivet groove 2 blind rivet 7 is housed, blind rivet 7 has steel ball bit-avoiding slot 8 at steel ball 4 correspondence positions, blind rivet 7 screw 9 of having locked, and screw 9 heads are equipped with pallet 10.
At least 2 of said steel ball 4, retainer 5 and handle 6 quantity are evenly distributed on around the blind rivet groove 2.
Outstanding positioning tooth 11 has stopper slot with positioning tooth 11 corresponding positions on the said pallet 10 on the said chuck body 1.
Shown in accompanying drawing 2, rotary handle 6, retainer 5 and then rotates, and retainer 5 is curved surfaces with the contact-making surface of steel ball 4; So steel ball 4 will be done radial slippage when retainer 5 rotated, and made blind rivet 7 move axially, blind rivet 7 and pallet 10 are for being fastenedly connected; Blind rivet 7 moves, and pallet 10 moves thereupon, relatively moving between pallet 10 and the chuck body 1; Spacing through positioning tooth 11, the purpose of invariant position when having played clamping repeatedly, and realize tension or the purpose of unclamping.
