The utility model relates to a gear hub clamp forms the little magnitude of interference through locking ball and product hole and coordinates, keeps product location face location effective, can fully guarantee gear hobbing processing technology requirements for quality, anchor clamps simple manufacture, and the product loading and unloading are convenient, can effectively improve process production efficiency.
Description
Technical field
This utility model belongs to gear teeth technical field, specifically, relates to a kind of gear teeth clamp.
Background technology
Existing gear hobbing operation all adopts expansion sleeve clamp or light mandrel fixture, and thus some practical problems occurs in work in-process.Expansion sleeve clamp in use lost efficacy fast because of expansion set, and machined product often occurs that teeth directional is free or the overproof problem of tooth runout, and often changes expansion set, relatively costly and affect production efficiency；Light mandrel fixture in use often occurs: because product endoporus controls 0.03mm margin of tolerance difficulty when Vehicle Processing, causing there is the assembling of portioned product difficulty in gear hobbing process, portioned product assembling is more loose affects gear hobbing process quality requirement.
Utility model content
For solving above technical problem, the purpose of this utility model is in that to provide a kind of gear teeth clamp, adopts ball retainer stationary positioned steel ball, and is set in the axle of fixture, steel ball circle distribution forms slight interference with holes of products surface and coordinates, and reaches complete locating effect.
This utility model purpose is achieved in that a kind of gear teeth clamp, it it is critical only that: includes axle, fixed stop, pressing plate and nut, one end of described axle is sequentially provided with construction section to the other end, workpiece positioning section and fastening section, described axle is installed fixing by construction section, described fixed stop is fixedly set between described workpiece positioning section and construction section, described workpiece positioning section is arranged with ball retainer, this ball retainer is provided with steel ball, described pressing plate is movably set in described fastening section, the end face of this pressing plate abuts with described ball retainer, described nut is threadeded with fastening section.
The external diameter of above-mentioned workpiece positioning section is more than the external diameter of described fastening section, described pressing plate is provided with stepped hole towards the one side of workpiece positioning section, this stepped hole is three rank, the macropore of this stepped hole is movably set in described fastening section, the mesopore of this stepped hole is movably set in workpiece positioning section end, and the aperture of this stepped hole is set in the end of ball retainer.
Being provided with internal spline in the aperture of above-mentioned stepped hole, the aperture of the corresponding described stepped hole of described fastening section is provided with external splines.
It is provided with packing ring between above-mentioned pressing plate and nut.
Beneficial effect:
This utility model one gear teeth clamp, the construction section of fixture is installed and in gear hobbing lathe table rest by fixed stop, clamping fixture for correcting axle, by mounted on the spindle for the ball retainer with steel ball, then workpiece to be processed is set on described ball retainer, then sheathed pressing plate packing ring successively, finally with nut check, work pieces process can be carried out, form slight interference amount thus by locking ball with product endoporus to coordinate, keep location, product orientation face effectively, can fully ensure that gear hobbing process Technology prescription, fixture makes simple, product handling are convenient, operation production efficiency can be effectively improved.
