Special differential shell type elastic clamping tooling for helical gear

Abstract

The invention discloses special differential shell type elastic clamping tooling for a helical gear, which comprises a differential shell type body, an elastic nut and an elastic sleeve, wherein the differential shell type body is provided with a connecting hole, a handling hole and a positioning hole, the connecting hole is used for directly connecting a main shaft of a grinding machine, the handling hole is used for putting a workpiece into the differential shell type body, and the positioning hole is used for positioning the workpiece; the elastic sleeve is installed in the positioning hole and matched with the positioning hole, the front end of the elastic sleeve extends out of the positioning hole, and the thickness of the elastic sleeve is gradually reduced in the axial direction of the elastic sleeve from the inner part of the differential shell type body to the outer part of the differential shell type body; and the elastic nut is sheathed on the front end of the elastic sleeve and matched with the elastic sleeve through threads. The special differential shell type elastic clamping tooling has the advantages of convenience in use and simple structure, the workpiece is positioned through an outer circle and an end surface, the elastic sleeve is pulled through the elastic nut to clamp the outer circle of the workpiece, so as to process an inner hole of the workpiece, and therefore, the coaxiality of the outer circle and the inner hole of a transfer case gear is better.

Description

technical field [0001] The invention designs a mechanical processing auxiliary tool, in particular to a differential shell type elastic clamping tool specially used for helical gears of a transfer case. Background technique [0002] In the existing market, the processing of the inner hole and the outer circle of the transfer gear needs to ensure coaxiality, such as figure 1 As shown, in the process of processing this product, it is required to ensure that the outer ring 2 is used as the reference, the runout of the tensioner clamp 1 and the concave tooth 4 is 0.05, and the coaxiality of the inner ring 3 relative to the outer ring 2 should be 0.02. In the original processing, the outer diameter and outer ring 2 of the upper mandrel are ground by the clamp 1, and then the inner ring 3 is processed by the internal grinding of the clamp 1. The outer ring 2 and the inner ring 3 of the product produced in this way There are 35% of the coaxiality of different degrees of out-of-tol...

Problems solved by technology

In the original processing, the outer diameter and outer ring 2 of the upper mandrel are ground by the clamp 1, and then the inner ring 3 is processed by the internal grinding of the clamp 1. The outer ring 2 and the inner ring 3 of the product produced in this way 35% of the coaxiality has different degrees of out-of-tolerance, and it is impossible to complete the processing of the workpiece at one time
