Ratchet, pin, dead head, the second holding screw, spring, connecting seat, adjusting nut；
It is upper top in tailstock tool sleeve, upper top axial movement is realized by tailstock pressure；Upper top lower end top
Firmly tooth axle upper end center hole；
Gripping sleeve be enclosed within tooth axle lower end it is cylindrical on, make gripping sleeve and tooth axle by being arranged on the first holding screw of gripping sleeve side
Fixed or release；Dead head is fixed on connecting seat top；Dead head is provided with circumferentially distributed end face ratchet, the embedded dead head of pin
And in end face ratchet radial hole；Gripping sleeve end face of the end face ratchet incision above dead head；
Dead head and connecting seat center are provided with mesopore, and floating centre is arranged in mesopore；Spring and adjusting nut are arranged at mesopore
Floating centre is withstood in interior bottom, spring upper end, and lower spring end is supported on adjusting nut；The elastic force of spring causes floating centre
Withstand tooth axle lower end centre bore in upper end；
Second holding screw extends radially through connecting seat outer wall, the axial direction on the inner embedded floating centre periphery wall of the second holding screw
In elongated slot.
Further, connecting seat is connected on the table by the second fixing screws.
Further, dead head is fixed on connecting seat top by the first axially arranged fixing screws.
Further, end face ratchet is circumferential uniform on dead head.
It is an advantage of the current invention that：
1）When this fixture roll flute is processed, tooth shaft end, is positioned using floating centre and upper top cooperation come positioning tooth axle without the need for lengthening
High precision, uniformity are good；
2）This fixture adopts Spring driving floating centre, it is ensured that can reliably positioning tooth axle centre bore；
3）This fixture cuts gripping sleeve end face so as to the produces driving force when tooth axle needs to rotate an angle using end face ratchet,
Drive it is reliable, the clamping of tooth axle roll flute with unload it is simple and efficient；
4）This fixture can conveniently adjust the amount of contraction of spring, with Reliable guarantee floating centre using adjusting nut come support spring
Reliable location tooth axle centre bore, while and ensureing that end face drives strong reliability；
5）This fixture roll flute, easy to operate, quick, good reliability meet the processing of tooth axle high accuracy and mass production requirement.
Description of the drawings
Fig. 1 is the structure composition schematic diagram of the present invention.
Specific embodiment
With reference to concrete drawings and Examples, the invention will be further described.
As shown in figure 1, the end face that the present invention is provided drives little tooth axle gear grinding clamp, including：Go up top 1, gripping sleeve 2, float
