Description
Technical field
The present invention relates to a kind of lathe and use chuck, is a kind of fit chuck of three-jaw four paws that possesses scroll chuck and chuck function simultaneously specifically.
Background technology
Traditional lathe chuck 250 commonly used and following chuck are generally scroll chuck, and chuck 300 reaches the above chuck of using more.Scroll chuck is usually used in clamping cylinder, plate-like workpiece, and chuck is usually used in clamping off-centre and the asymmetric workpiece of profile.The workpiece profile is different in working at ordinary times, needs frequent frequent change chuck to adapt to three-jaw or four paws clamping workpiece, and manually-operated is loaded down with trivial details, inefficiency, and positioning accuracy is low.
In addition, scroll chuck only is furnished with one group of claw usually, and usually processes various finding in the actual processing; The excircle part of clamping is different in size, needs to be used for the clamping finding, the long-term fragile claw of turning claw at the claw seam of getting on the bus out; Reduce the claw clamping accuracy, reduce service life.
Summary of the invention
In order to address the above problem, the invention provides a kind of compact conformation, integrate scroll chuck and chuck function, clamp effectively, positioning accuracy is high, the fit chuck of three-jaw four paws applied widely.
The technical scheme that the present invention adopts is: the fit chuck of a kind of three-jaw four paws; Comprise chuck body; It is characterized in that: said chuck body is provided with three-jaw dog group and four paws dog group; Chuck body is provided with the cone pinion and the large bevel gear parcel body of the transmission that is meshing with each other, and large bevel gear parcel body is connected through the flat thread auxiliary driving with the three-jaw dog group; Also be provided with the adjusting screw mandrel on the chuck body, regulate screw mandrel and four paws dog group and be in transmission connection through screw thread pair; Connect a fixture block on the said adjusting screw mandrel, fixture block and parcel body or be disengagement or clamping state with large bevel gear parcel body.
Said three-jaw dog group and four paws dog group be a shared claw on chuck body.
The claw of said three-jaw dog group and four paws dog group comprises claw pedestal and pawl head; Claw pedestal and large bevel gear parcel body or regulate the rectangular screw thread pair of the screw mandrel state that is in transmission connection; The pawl head is the multilayer staircase structural model, and the pawl head tightly is fixedly connected with the claw pedestal on the step end face of pawl head through bolt, nut assembly.
Said pawl head connects a block through bolt on arbitrary side.
Compared with prior art, the present invention has the following advantages:
1, adopts spanner to drive cone pinion and drive large bevel gear parcel body, thereby drive to the clamping use that the three-jaw dog group can realize the three-jaw claw through the flat thread pair; Adopt spanner to drive the adjusting screw mandrel and drive to the clamping use that the four paws dog group can realize the four paws claw; When fixture block and large bevel gear parcel body are disengaged condition; Large bevel gear parcel body is connected with regulating not to have between screw mandrel, and driving adjusting screw mandrel can be realized the single action clamping of four paws dog group, when fixture block and large bevel gear parcel body are the clamping state; Large bevel gear parcel body is connected with the adjusting screw mandrel; Driving large bevel gear parcel body can be realized the self-centering clamping of four paws dog group through regulating screw mandrel, and is applied widely, satisfies the clamping requirement of various workpiece;
2, three-jaw dog group and four paws dog group adopt the fabricated structure of claw pedestal and pawl head, can reduce manufacturing cost, safeguard that only needing to change the pawl head gets final product; Adopt bolt, nut to piece together tight pawl head on pawl caster bed rank, and connect a block through bolt on the arbitrary side of pawl head, when no matter claw is made positive pawl or anti-pawl and used; By nut or block positive stop, need not simplify operation at the claw seam clamping parts of getting on the bus out as workpiece; Reduce labour intensity, help increasing work efficiency, and claw does not have damage; The clamping precision is high, long service life.
The present invention gathers traditional three-jaw dog group and four paws dog group on chuck body; Make large bevel gear parcel body and regulate screw mandrel and be and throw off or connection status realizes the independent use of three-jaw card group and four paws dog group respectively through fixture block; Its compact conformation; Simple operation in the service life that helps improving clamping precision, operating efficiency and chuck, is satisfied the clamping requirement of each workpiece.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: chuck body 1, three-jaw draw-in groove 2, claw pedestal 3, pawl head 4, four paws draw-in groove 5, cone pinion 6, large bevel gear parcel body 7 is regulated screw mandrel 8, fixture block 9, chuck rear pressing cover 10, chuck balance weight 11, nut 12, block 13.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1, shown in 2, the fit chuck of a kind of three-jaw four paws comprises chuck body 1, three-jaw draw-in groove 2, claw, four paws draw-in groove 5, cone pinion 6, large bevel gear parcel body 7 is regulated screw mandrel 8, fixture block 9, chuck rear pressing cover 10 and chuck balance weight 11.Chuck body 1 is provided with and is arranged with three road three-jaw draw-in grooves 2 and four road four paws draw-in grooves 5; Wherein one three-jaw draw-in groove 2 is shared with four paws draw-in groove 5; Be equipped with claw in three-jaw draw-in groove 2 and the four paws draw-in groove 5, chuck body 1 is provided with and is used for balance three road three-jaw draw-in grooves 2 and four road four paws draw-in grooves 5 are provided with asymmetric chuck balance weight 11 on chuck body 1; The circumference of chuck body 1 is provided with cone pinion 6 radially; Chuck body 1 back side is packaged with large bevel gear parcel body 7 through chuck rear pressing cover 10; The bottom of claw and large bevel gear parcel body 7 are in transmission connection cone pinion 6 and large bevel gear parcel body 7 engaged transmission through the planar rectangular screw thread pair; Be equipped with on the chuck body 1 of per pass four paws draw-in groove 5 bottoms and regulate screw mandrel 8; Regulate screw mandrel 8 and parcel body 1 or with large bevel gear parcel body 7 rectangular screw thread pair engagements; The bottom of claw is connected through the rectangular thread auxiliary driving with adjusting screw mandrel 8; Regulate clamping one fixture block 9 on the screw mandrel 8, fixture block 9 is with large bevel gear parcel body 7 with parcel body 1 or fixture block 9 and throws off or the clamping state.
