Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
It please refers to Fig.1 to Fig.3, the utility model provides a kind of top circle processing device of tooth shaft part, including main shaft 1, tailstock 2
With clamping piece 3, clamping piece 3 is set to the tail end of tooth shaft part 4, and main shaft 1 is against the tail end of tooth shaft part 4, and tailstock 2 is against tooth shaft part 4
Head end, the clamping piece 3 include fixed ring 5, the fixed ring 5 be equipped with several screw holes and a mounting hole, it is described several
Screw hole and a mounting hole are circumferentially uniformly distributed, and twist-on has screw rod 6 in the screw hole；It is set in mounting hole by the connection of articulated shaft 7
There is clamping arm 8, the clamping arm 8 includes snap arm 9 and pressure arm 10, is equipped with hinge at the center of snap arm 9 Yu the boundary position of pressure arm 10
Hole is connect, articulated shaft 7 is arranged in hinge hole, and 9 length of snap arm is greater than the length of pressure arm 10, and 9 length of snap arm is at least pressure arm
Twice of 10 length；Spring 11 is connected between the outer wall of the snap arm 9 and the periphery wall of fixed ring 5, spring 11 to compress
Arm 8 rotates around articulated shaft 7 and rotates snap arm 9 towards the outside of fixed ring 5 always；The outer wall of the snap arm 9 is equipped with card slot 12；
The main shaft 1 is equipped with eccentric rod 13, the axis of the main shaft 1 and the axis of fixed ring 5 be it is conllinear, eccentric rod 13 is matched and is pressed in
In card slot 12.
The inner end of the screw rod 6 has rubber sleeve 14, and 14 twist-on of rubber sleeve is on screw rod 6；Before the lower end of the pressure arm 10
Equipped with rubber block 15, there is trapezoidal abaculus 16 on the rubber block 15, the caulking groove 17 of 10 lower end of pressure arm is arranged in trapezoidal abaculus 16
It is interior.
9 side of snap arm is equipped with active gag lever post 18, and 5 periphery of fixed ring is equipped with matched with active gag lever post 18
Driven gag lever post 19.
The working principle of the utility model is as follows:
The top circle processing device of the tooth shaft part of the utility model, for processing the transmission shaft in automobile gearbox, first
Screw rod 6 is unclamped, in addition, clamping arm 8 is in the open state by the elastic force effect of spring 11, in this way, the inner hole of fixed ring 5 is presented
Full-size, by the inner hole of one end insertion fixed ring 5 of transmission shaft, then, rotary screw 6 makes screw rod 6 radially close to transmission
The outer surface of axis 0；The main shaft 1 of lathe and tailstock 2 are all provided with to the form for being set to top tip structure, in this way, the both ends of transmission shaft are pushed up
Point resists, at this point, the eccentric rod 13 of 1 end of main shaft is also synchronous with main shaft 1 when main shaft 1 rotates and drives transmission shaft synchronous rotary
Rotation, and snap arm 9 is in the radius of turn of eccentric rod 13, in this way, eccentric rod 13 presses to snap arm 9 and has to snap arm 9 larger
Active force, at this point, entire clamping arm 8 is rotated around articulated shaft 7, so that pressure arm 10 be made to squeeze to transmission axis direction, finally with two
A screw rod 6 cooperates, and realizes the clamping purpose to transmission shaft, and this clamping is to be acted on determining according to 1 rotary force of main shaft, Neng Gouqi
To the effect of two top tip structures of auxiliary, the stable holding to transmission shaft is kept, the outer of transmission shaft can be protected to greatest extent
Surface.
And work as transmission shaft after processing is completed, and it being acted on by spring 11, clamping arm 8 forms the rotation of opposite direction around articulated shaft 7, from
And unclamp transmission shaft.
In order to protect transmission shaft to greatest extent, the protection of rubber material is especially increased on screw rod 6 and clamping arm 8
Structure.
Clamping arm 8 is acted on clamping arm 8 caused by release overturning excessively outward by spring 11 and can not accurately located in order to prevent
In in the radius of turn region of eccentric rod 13, active gag lever post 18 and driven gag lever post 19 are especially increased, when clamping arm 8 unclamps
When transmission shaft, active gag lever post 18 is finally blocked by driven gag lever post 19.
