Background technology
Gear is an element of gearbox, and automatic gear-box gear is generally by helical gear and with reference to toothed ring gear
It is welded, it is very high to the circularity of the combination gear ring conical surface, straightness, surface roughness requirements.And gear type is more, batch
Greatly, it is desirable that Gear Production has high-precision, high flexibility, efficient characteristic.Since the face that gear need to be ground is the conical surface, with revolution
Center is into certain cone angle, therefore gear conical surface grinding cannot be processed on plain external grinding machine, it is necessary to which by workhead, (fixture returns
Turn center) one angle realization conical surface grinding of one angle of deflection or grinding carriage deflection.
For the gear conical surface clamp of the prior art generally using pneumatically or hydraulically expansion sleeve clamp come clamping, hydraulically operated fixture can
To share Hydraulic Elements with machine tool hydraulic system hydraulic station, design pneumatic circuit is not required to, air-actuated jaw is simple in structure, at low cost,
Maintenance is convenient, but lathe need to increase dedicated pneumatic system circuit.Clamp pull rod, expansion set and locating cone three are free rotations
Turn, expansion set is first packed into positioning cone seat when fixture assembles, pull rod is inserted into and pull rod is screwed into pneumatic piston rod, by adjusting drawing
The length that bar is screwed into controls the tightness of expansion set.Using this structure fixture clamping workpiece when, work spindle drive folder
Tool positioning seat is rotation, and workpiece can also circumferentially rotate in clamping, this leads to fixture, and pull rod can be from use for some time
It is loosened in piston rod;And workpiece can not also detect whether on the fixture positioning seat smooth, whether clamping power is enough.

Enter clamp body, control the length in gap, make the utility model do not install expansion set limitation taut length is tensed in the case of workpiece will not
In the excessive distending damage of expansion set.
Preferably, the clamp body air flue is equipped with air flue plug.After the completion of work pieces process, air flue plug is opened by air flue
Interior compressed air release.
Preferably, the pull rod is circumferentially with several first sealing rings.
Preferably, the second sealing ring is equipped between the clamp body and positioning seat.
The sealing ring of setting ensure that the seal of entire air flue.
Compared with prior art, the beneficial effects of the utility model are:1st, not needing to, which increases dedicated pneumatic system, returns
Road, pull rod air flue directly is passed through compressed air can detect workpiece and the accuracy of clamp body positioning;2nd, it is anti-by first
Rotation mechanism and the second rotation-preventing mechanism prevent workpiece rotation from causing to loosen the use for influencing entire fixture;3rd, using modularized design,
When remodel production or clamp wear are with changing, only need to replace seldom a part of part (positioning seat, expansion set) can continue to give birth to
Production, saves the non-processing time, enhances equipment processing flexibility.
