Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at A-A in Fig. 1；
Fig. 3 is the partial enlarged drawing at B-B in Fig. 1.
Embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1,2 and 3, the utility model proposes be applied to duplex-gear be heat-treated after finishing of internal diameter fixture consolidate
Determine structure, including chuck body 1, the inside of chuck body 1, which has one, can house the working cavities 3 of duplex-gear workpiece 2, work
Inner chamber 3 has to be respectively mounted on two the first installation positions 4 and the second installation position 5 in shaft shoulder shape, first, second installation position 4,5
There are front tapered sleeve 6, rear tapered sleeve 7, the inside of front tapered sleeve 6 is provided with preceding pellet clip assembly 8, and the inside of rear tapered sleeve 7 is provided with rear pellet
Clip assembly 9, preceding pellet clip assembly 8 is identical with the structure of rear pellet clip assembly 9, and preceding pellet clip assembly includes inner cone retainer
10, the lateral surface elasticity of inner cone retainer 10 is clamped in the medial surface of front tapered sleeve, and the madial wall of inner cone retainer 10
Provided with a circle pellet host cavity 11, one group of front clamp pellet 12 for being exposed to accent, rear pellet are housed in pellet host cavity 11
Clip assembly 9 includes rear cone retainer 13 and rear clamping pellet 14, and duplex-gear workpiece 2 is by being gradually forwardly inserted working cavities
And then the face portion of duplex-gear workpiece both sides is not fixedly clamped by front clamp pellet 12 and the rear pellet 14 that clamps.
The front side portion of chuck body 1 is provided with the right-hand member ring flange 15 for being used for being fixed on chuck body 1 on grinding machine, right-hand member method
The side of blue disk 15 is provided with matched and is fixed on left end ring flange 16, and left end ring flange and right-hand member ring flange are provided with
Corresponding bolt hole 17.The side wall of chuck body 1, which is provided with, to be used to distinguish axial restraint front tapered sleeve 6 and determines for a pair of rear tapered sleeve 7
Position screw hole, positions fixation in set screw hole by installing positioning screw 18 by front tapered sleeve 6 and rear tapered sleeve 7.Front tapered sleeve 6 is with after
Tapered sleeve 7 is connected with the cavity wall of working cavities 3 using interference fit.Front tapered sleeve 6 and inner cone retainer are connected using interference fit
Connect, rear tapered sleeve and rear cone retainer are thus conveniently detachable also using interference fit connection, play and compress pellet with the conical surface
The effect of clip assembly.
When specifically used, chuck body and front tapered sleeve, rear tapered sleeve are by together with being interference fitted compression fit, and to pass through
Set screw is fixed together, and is fixedly connected on jointly with bolt on the flange seat of grinding machine, during each product handling, this part zero
Part is motionless, it is not necessary to dismantle.
Preceding pellet clip assembly and rear pellet clip assembly are all made up of conical surface retainer and pellet, and conical surface retainer is a kind of
Elastic expansion-sleeve, can contract deformation of rising within the specific limits.Pellet is stuck in the gear tooth slot of duplex-gear workpiece when using, and passes through work
Conical surface retainer on the tapered sleeve, need to be applied certain pressure vertically or tap work end by part in the end face of workpiece during clamping
Face, the conical surface is moved pellet clip assembly vertically before driving, and conical surface retainer is shunk, and is realized and is clamped the small of duplex-gear workpiece
Tooth；After preceding pellet clip assembly is clamped, apply certain pressure vertically in the conical surface retainer end face of rear pellet clip assembly or strike
Conical surface retainer end face is hit, the conical surface is moved vertically, conical surface retainer is shunk, realize the canine tooth for clamping duplex-gear workpiece；
It is achieved thereby that simultaneously clamping on the purpose of the big little gear of duplex-gear workpiece, serve while by the positioning of duplex-gear workpiece twice tooth
Effect.
Due to being to lean on the positioning of twice tooth to process endoporus, so the endoporus processed with this method, can be protected simultaneously
Demonstrate,prove the precision of size twice gear.After duplex-gear inner hole of workpiece is machined, only copper rod technique at the two of chuck body need to be used
The conical surface retainer end face of preceding pellet clip assembly and rear pellet clip assembly is prized in hole outward, the conical surface vertically is allowed to and moves outward,
Conical surface retainer carries out spreading, and duplex-gear workpiece unclamps, so that duplex-gear workpiece is removed.
Above-described embodiment only expresses several embodiments of the present utility model, and it describes more specific and detailed, but simultaneously
Can not be therefore understands that being the limitation to the utility model the scope of the claims.It should be pointed out that for the ordinary skill people of this area
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With new protection domain.Therefore, the utility model patent and protection domain should be defined by appended claims.
