Description
Technical field
The invention belongs to machining fixture fields, more particularly, to a kind of gear ring cylindrical turning fixture.
Background technique
Existing large diameter thin wall class gear ring mainly steps up mode using 4 kinds at present in size process:
1. lathe chuck+anti-pawl tensioner gear ring inner hole form；
2. mandrel+integral type ringfeder draws the form of mandrel clamping gear ring inner hole；
3. mandrel+integral type ringfeder draws the form of ringfeder clamping gear ring inner hole；
4. mandrel+end face gland compresses the form of gear ring end face；
It is uneven to inner hole and end face each side expanding force all to there is fixture in this 4 kinds of methods, and after processing is completed, gear ring outer circle becomes
Shape amount is big, and gear ring wall unevenness is even, influences the processing of tooth process processed below.
Summary of the invention
In view of this, the present invention is directed to propose a kind of gear ring cylindrical turning fixture, to guarantee gear ring uniform wall thickness.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of gear ring cylindrical turning fixture, including shell and expansion assembly, expansion assembly is driven to be moved on shell；Shell
Body includes mandrel and positioning disk, and mandrel body side has the conical surface, and positioning disk top surface is formed with the positioning surface vertical with mandrel axis；
