The use requirement of vehicle driving shaft assembly is more special, and it needs to rotate at a high speed in transmitting torque, so, with
People are jerk value to driving-shaft assembly, dynamic flat to Automobile Design hommization, the requirement more and more higher to automobile ride comfort
The requirement also more and more higher of weighing apparatus precision and residual unbalance, value.
Existing driving axle end tooth nosing fork uses end tooth bead when two earhole metalworking operations is carried out in CNC milling machine
Two bolts hole of fork are positioned and carry out boring processing, and car jump-ring slot, reaming operation, positioned with earhole in numerically controlled lathe, so
In the two procedures of earhole processing, positioning and clamping, positioning datum disunity twice are used, caused earhole precision to meet
Use requirement.This phenomenon can cause adverse consequences：First, two earhole jump-ring slots distance is uneven, and symmetry is overproof；2nd, earhole
Partially, earhole form and position tolerance is overproof for easy boring, and influence is assembled and the initial dynamic balancing value of dynamic balancing, influences product quality.Therefore it is existing
Driving axle end tooth nosing fork boring earhole, car jump-ring slot fixture can not meet driving-shaft assembly bounce and it is dynamically balanced will
Ask, therefore, we actively develop a kind of new driving axle end tooth nosing fork boring earhole, car jump-ring slot fixture, substitute tradition
Driving axle end tooth nosing fork boring earhole, car jump-ring slot fixture.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of new driving axle end tooth nosing fork boring earhole, car
Jump-ring slot fixture, solves driving axle end tooth nosing fork fixture of the prior art to two ears in processing driving axle end tooth nosing fork
Hole jump-ring slot distance is uneven, the easy boring of earhole is inclined, and earhole form and position tolerance is overproof, influence assembling and the initial dynamic balancing value of dynamic balancing etc.
Problem.
The utility model is that the technical scheme that solution above-mentioned technical problem is used is：A kind of driving axle end tooth nosing fork boring
Earhole, car jump-ring slot fixture, including chuck body, positioning disk and Hydraulic Clamping Mechanism, the chuck body are middle axial direction

Face, and two positions of floating V-block are adapted with the position of the earhole of end tooth flange york two, the upper end of the pressing plate and hydraulic cylinder
Piston rod be fixedly connected.
As a kind of this new driving axle end tooth nosing fork boring earhole, the further improvement of car jump-ring slot fixture：It is described
The lower surface of floating V-block offers the arc groove that can be cooperated with the ear upper surface of flange york.
As a kind of this new driving axle end tooth nosing fork boring earhole, the further improvement of car jump-ring slot fixture：It is described
The arc groove inwall of floating V-block is provided with anti-slip veins, to increase the positional accuracy of end tooth flange york.
As a kind of this new driving axle end tooth nosing fork boring earhole, the further improvement of car jump-ring slot fixture：It is described
The via bottoms of chuck body are provided with the groove for installing positioning disk, and positioning disk is fixed by screws in the recessed of chuck body
In groove.
Beneficial effect
A kind of driving axle end tooth nosing fork boring earhole of the utility model, car jump-ring slot fixture, are carrying out power transmission shaft end tooth
Original two cumbersome positioning steps are reduced to once accurately position fixing process during flange york earhole metalworking, processing
Two lathes are kept to a machine tool, improve production efficiency, reduce production cost, it is often more important that can protect to greatest extent
Card element precision, is positioned with end tooth, improves positioning precision, and clamping, positioning is not repeated, unifies positioning datum, is disappeared
Various accumulations of error during except metalworking, improve the dimensional accuracy of earhole, ensure that assembling inter-axle shaft is total to greatest extent
