Abstract
The invention relates to a self-centering double-support chuck for fixing an axis part with axis centering requirement, which comprises a fixing assembly and a power input assembly. The fixing assembly comprises a first fixed support. The inside of the first fixed support is provided with a through hole. A tip cone shaft passes through the through hole. One end of the tip cone shaft is connected with a reciprocating mechanism, while the other end thereof is connected with a signal tip cone. The single tip cone 7 can rotate with the tip cone shaft. A positioning mechanism which prevents the tip cone shaft from rotating is arranged between the tip cone shaft and the first fixed support. The power input assembly comprises a second fixed support. The inside of the second fixed support is provided with a through hole. A power input shaft passes through the through hole. One end of the power input shaft is connected with a multiple tip cone, while the other end thereof is externally connected with a power source. The multiple tip cone has at least two cone surfaces. The self-centering double-support chuck adopts the cone surfaces of the single tip cone and the multiple tip cone to clamp the axis part, and realizes automatic centering by the action of the cone surfaces, and reduces the processing requirements for the axis part and assembling difficulty.

Background technology
Chuck is mainly used to the shaft element that has axis centering to require of fixing often dismounting.The axle base part directly is placed on the chuck usually, and the fixed connection of chuck own is to equipment.
Usually chuck is made up of two parts, shaft element is formed bilateral support.The two ends of chuck and axial workpiece are fixedly clamped by square groove and square toes.The axis centering of axial workpiece need guarantee by the cooperation of square groove and square toes.Flute profile cooperates installation on the one hand the square toes processing of axial workpiece and the square groove of chuck to be processed with higher processing request, and assembling is cooperated also has the degree of precision requirement on the other hand.In addition, often the square mating surface of dismounting since factor affecting such as crudy and wearing and tearing usually with inevitable fit clearance, so that when being assembled the axial workpiece rotation, produce shake and noise, may influence the quality of the processing environment and the production product of equipment operation simultaneously.
Summary of the invention
The object of the present invention is to provide a kind ofly to heart double-support chuck, realize automatic centering, reduce requirement processing and assembling.
A kind of to heart double-support chuck, comprise fixation kit and power input module, it is characterized in that:
Fixation kit comprises first hold-down support 8, addendum cone axle 3, reciprocating mechanism, single addendum cone 7 and detent mechanism, first hold-down support, 8 inside have through hole, and addendum cone axle 3 passes this through hole, and an end connects reciprocating mechanism, the other end connects single addendum cone 7, and single addendum cone 7 can be around 3 rotations of addendum cone axle; Be provided with the detent mechanism that prevents 3 rotations of addendum cone axle between the addendum cone axle 3 and first hold-down support 8;
The power input module comprises second hold-down support 16, power input shaft 15 and many top cones 12, second hold-down support, 16 inside have through hole, and power input shaft 15 passes this through hole, and an end connects many top cones 12, the external power source of the other end, many top cones 12 have at least two taper seats.
The present invention adopts the taper seat of single addendum cone and many top cones to clamp described axial workpiece, by the effect realization automatic centering of taper seat.To only needing before the heart,, reduce that Machining of Shaft-type Parts is required and assembly difficulty with respect to prior art at axial workpiece two ends processing circular hole or bellmouth.

The specific embodiment
The present invention comprises fixation kit and power input module from the better embodiment to heart double-support chuck.
See also Fig. 1 to 2, fixation kit comprises single addendum cone 7, hold-down support 8 and piston cylinder 2.Piston cylinder 2 can be selected cylinder or hydraulic cylinder for use, and it comprises cylinder body and piston rod.The piston rod of piston cylinder 2 is connected with an end of addendum cone axle 3 by screw thread, in order to prolong the piston rod of described piston cylinder 2.Single addendum cone 7 cooperates the back to be fixed on the inner ring of bearing 5,6 with jump ring 4 with duplex bearing 5,6; The outer ring of bearing 5,6 is fixed in the endoporus of addendum cone axle 3 other ends, can move back and forth under the effect of piston cylinder 2 time free to rotate with bonding addendum cone 7.Through hole is offered at the middle part of hold-down support 8, and addendum cone axle 3 and single addendum cone 7 pass described through hole.Stationarity for 7 motions of bonding addendum cone is equiped with linear bearing 9 between the through hole of described hold-down support 8 and the addendum cone axle 3, and described linear bearing 9 is fixed in the through hole of hold-down support 8.Offer axial U type groove on the described addendum cone axle 3, pin 19 shown in Figure 2 cooperates the U type groove of addendum cone axle 3 to guarantee that described addendum cone axle 3 does not rotate.Riser 1 is connected back fixed head as piston cylinder 2 with hold-down support 8 by bolt described piston cylinder 2 is fixed on the described hold-down support 8.Stiff end carriage 10 is fixed on the bearing 8, supports as the interim placement of clamped axle.Obviously, described piston cylinder 2 can substitute with other reciprocating mechanism, for example screw mandrel or linkage etc.
See also Fig. 3 to 4, the power input module comprises many top cones 12, power input shaft 15 and hold-down support 16.Have at least two taper seats on described many top cones 12, can be single processing parts, also can be divided into the assembly of a plurality of bocca parts as required.Power input shaft 15 is by bearing 14,17 and be installed on the hold-down support 16. Bearing cap 13 and 18 guarantees the axial location of bearing 14,17.Many top cones 12 are fixed at an end of power input shaft 15.Input carriage 11 is fixed on the bearing 16, as interim support.
See also Fig. 5, one and a plurality of circular holes or bellmouth are offered to single addendum cone 7 and many top cones 12 respectively in the two ends of an axial workpiece 20.Described axial workpiece 20 is clipped between fixation kit and the power input module.External power source provides rotational power by shaft coupling 21 equijoin parts for the power input module.Chuck cooperates by the single taper surface 30a of single addendum cone 7 and the taper surface 30b hole corresponding with axial workpiece 20 two ends of many top cones 12.During axle base part 20 clampings, at first closure piston cylinder 2 sources of the gas guarantee the cylinder piston withdrawal, and axle base part 20 is placed on carriage 10 and 11.Open source of the gas then, the piston rod of piston cylinder 2 stretches out, and cooperates promotion axial workpiece 20 to cooperate with the conical surface 30b of many top cones 12 with the hole of axial workpiece 20 1 ends by single addendum cone 7.Effect by taper seat realizes clamping and centering, and a plurality of taper seats on many top cones 12 can provide torque for axial workpiece 20 simultaneously.During dismounting axial workpiece 20,, stop axle and rotate at first by stopping extraneous input torque; Close source of the gas then, the piston rod of piston cylinder 2 drives single addendum cone 7 withdrawals, and axle 20 breaks away from the cooperation of the conical surface 30b of many top cones under the gravity effect, hang naturally to carriage 10 and 11.
