Abstract

The utility model relates to a gear milling clamp of a thin wall member. The gear milling clamp comprises a pedestal and a gear milling mandrel, and is characterized in that a double-end bolt is arranged on the pedestal, a spring and a pressure plate are arranged on the double-end bolt which is fixed on the pedestal through a hexagonal nut, the pressure plate comprises a pressure head, a connecting back with an adjusting screw and a support column, a positioning cylinder and an opening gasket are arranged on the gear milling mandrel, the positioning cylinder comprises a positioning end and a cylindrical shell, the external diameter of the positioning end is 8-12mm larger than the external diameter of the cylindrical shell, the external diameter of the positioning end is 0.04-0.1mm smaller than the internal diameter of the thin-wall outer spline of a part, and the gear milling mandrel is secured on the pedestal through an inner hexagonal screw. The gear milling clamp is simple in structure, easy for manufacture and convenient for mounting and dismounting parts. The thin wall outer spline end of a part is positioned in an auxiliary manner through the positioning cylinder, and the thin wall outer spline end of the part may not swing when the gear shaping machine shapes gears. Shaping gears are high in precision and stable in quality, and the qualified rate and the processing efficiency of shaping gears of the thin-wall outer spline of parts are improved. The production cost is reduced.

Description

A kind of thin-wall part gear-shaping clamp
Technical field
The utility model relates to a kind of gear-shaping clamp, is specifically related to a kind of thin-wall part gear-shaping clamp.
Background technology
Roller gear with external splines, and external splines position is thin-wall part; thin-walled length reaches 70 millimeters, and minimum thickness only has 3 millimeters, and while directly inserting external splines on this thin-wall part with gear shapping machine; thin-walled position easily swings; unstable product quality, and qualification rate is low, long processing time, expense are high; even cannot reach spline permissible accuracy, cause roller gear to be scrapped.This just needs the thin-walled position dead beat that guarantees to arrange flowers in key process of a kind of fixture simple in structure, easy to use moving, guarantees the machining accuracy of external splines, improves the qualification rate of product, reduces manufacturing expense.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of simple in structure, easy to manufacture, easy to loading and unloading, for the thin-wall part gear-shaping clamp of roller gear thin-walled external splines processing.
Thin-wall part gear-shaping clamp of the present utility model, comprises base and gear shaping axle, it is characterized in that: described base is provided with stud, and stud is provided with spring and pressing plate, and is fixed tightly on base by hex nut; Described gear shaping axle is provided with location cylinder and open washer, and is fixed tightly in gear shaping axle by little bead nut; Described gear shaping axle is fixed tightly on base by soket head cap screw.
In order better to realize above-mentioned purpose:
Described pressing plate consists of pressure head, the connection back of the body and support column, connects back and is provided with adjusting screw.
Described location cylinder consists of positioning end and cylindrical shell, large 8~12 millimeters than cylindrical shell external diameter of positioning end external diameters.
Described positioning end external diameter is less 0.04~0.1 millimeter than the internal diameter of the thin-walled external splines of part.
Thin-wall part gear-shaping clamp of the present utility model is simple in structure, easy to manufacture, part is easy to loading and unloading; Thin-walled external splines end auxiliary positioning by location cylinder to part, during gear shapping machine gear shaping, the thin-walled external splines end of part can not swing, and gear shaping precision is high, steady quality, the qualification rate and the working (machining) efficiency that have improved the thin-walled external splines gear shaping of part, reduced production cost.
