Abstract

The utility model discloses a kind of eccentric shaft turning fixture.It comprises chuck seat, the rotating disk being fixedly mounted on the ring flange on chuck seat and being arranged on ring flange, rotating disk has many deep-slotted chip breakers; Be serially connected with the securing member being positioned at deep-slotted chip breaker between rotating disk and ring flange, rotating disk can be rotated relative to ring flange and spacing by securing member; Rotating disk is installed with self-centering chuck, ring flange and rotating disk are provided with the pin-and-hole being positioned at Difference angles, when the heavy merga pass in a pin-and-hole position alignment pin location of rotating disk and ring flange, the centre of gyration of self-centering chuck center and chuck seat is made to form eccentric e.Its beneficial effect is the requirement of the operative skill not only reduced workman, reduces labour intensity, and production efficiency is high, substantially increases product percent of pass, also improves machining accuracy, and in mass production eccentric shaft parts, effect is particularly evident.

Description

Eccentric shaft turning fixture
Technical field
The utility model relates to a kind of frock clamp of eccentric shaft parts, specifically a kind of eccentric shaft turning fixture.
Background technology
For eccentric shaft parts, traditional processing method has: clamping centering on independent chuck clamping centering, floral disc enterprising luggage folder centering, self-centering chuck.Above three kinds of methods not only require high to the operative skill of workman, and labour intensity is large, and production efficiency is low, and the probability easily producing waste product is high.They can only be adapted to the production of the not high single and mini-batch production workpiece of ask for something precision.But and adopt common special fixture because avoiding producing mobile due to centrifugal force, and affect efficiency and the precision of whole work pieces process.
Summary of the invention
The technical problems to be solved in the utility model is to provide one not only can reduce labour intensity, improves product percent of pass, can also enhance productivity and the eccentric shaft turning fixture of machining accuracy.
In order to solve the problems of the technologies described above, eccentric shaft turning fixture of the present utility model, comprises chuck seat, and the rotating disk being fixedly mounted on the ring flange on chuck seat and being arranged on ring flange rotating disk has many deep-slotted chip breakers; Be serially connected with the securing member being positioned at deep-slotted chip breaker between rotating disk and ring flange, rotating disk can be rotated relative to ring flange and spacing by securing member; Rotating disk is installed with the self-centering chuck for holding workpiece, ring flange and rotating disk are provided with the pin-and-hole being positioned at Difference angles, when the heavy merga pass in a pin-and-hole position alignment pin location of rotating disk and ring flange, the centre of gyration of self-centering chuck center and chuck seat is made to form eccentric e.
Be provided with lining in the pin-and-hole of described rotating disk, have the vertically disposed spring with alignment pin in described alignment pin, between described spring and lining, be provided with steel ball.
The beneficial effects of the utility model are by arranging ring flange and the rotating disk that can rotate relative to ring flange between chuck seat and chuck, on ring flange and rotating disk, be provided with the pin-and-hole being positioned at Difference angles simultaneously, thus when the heavy merga pass in a pin-and-hole position alignment pin location of rotating disk and ring flange, the centre of gyration of self-centering chuck center and chuck seat is made to form eccentric e, make it that conventional lathe equipments can be utilized to carry out eccentric shaft parts processing, not only reduce the requirement of the operative skill to workman, reduce labour intensity, and production efficiency is high, substantially increase product percent of pass, also improve machining accuracy, what arrange has spring, the alignment pin of steel ball structure, the adverse effect that the movement operationally produced due to centrifugal force brings can be avoided, in mass production eccentric shaft parts, effect is particularly evident.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model eccentric shaft turning fixture;
Fig. 2 is that the K of Fig. 1 is to structural representation;
Fig. 3 is that the C-C of Fig. 2 is to structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, eccentric shaft turning fixture of the present utility model is described in further detail.
As shown in the figure, eccentric shaft turning fixture of the present utility model, comprises chuck seat 1, and the rotating disk 3 being fixedly mounted on the ring flange 2 on chuck seat 1 and being arranged on ring flange 2 rotating disk 3 has three deep-slotted chip breakers 4; Be serially connected with three securing members laid respectively in three deep-slotted chip breakers between rotating disk 3 and ring flange 2, by such structure, rotating disk 3 can be rotated relative to ring flange and spacing by securing member; Rotating disk 3 is installed with the self-centering chuck 5 for holding workpiece, ring flange 2 and rotating disk 3 are respectively arranged with the pin-and-hole being positioned at Difference angles, when pin-and-hole position heavy merga pass alignment pin 6 of rotating disk 3 and ring flange 2 is located, the centre of gyration of self-centering chuck 5 center and chuck seat 1 is made to form eccentric e.
Further, lining 7 is provided with in the pin-and-hole of the rotating disk 3 in the utility model, the vertically disposed spring 8 with alignment pin is had in alignment pin 6, steel ball 9 is provided with between spring 8 and lining 7, wherein, also be provided with the limit part for spacing steel ball 9 in lining 7, steel ball 9 by spring force pressure we in the limit part of lining.
Principle of the present utility model is as follows:
Overlap with the center of circle of securing member because of the center of circle of 3 deep-slotted chip breaker circular arcs, self-centering chuck center overlaps with the centre of gyration of lathe spindle, alignment pin is inserted in the A position, hole shown in Fig. 2, namely can go out the circle of diameter phi 100 by car; Rotating disk is turned over a corresponding angle around securing member relative to ring flange 2, makes the centre of gyration of self-centering chuck center and lathe spindle form eccentric e=12, now alignment pin is inserted in the B position, hole shown in Fig. 2, namely can go out the off-centre operation of diameter phi 180 by car; Haveing suffered in clamping and process, because there is the device of spring top steel ball, the play of alignment pin is being restricted, thus prevents the movement of whole frock clamp, directly improve the precision of workpiece in whole process.
