Automatic splined hub machining equipment with function of integrally forming tooth profile

Abstract

The invention discloses an automatic splined hub machining equipment with the function of integrally forming a tooth profile, and relates to the technical field of automobile part production. The equipment specifically comprises a conveying belt, a quantitative conveying mechanism, an inner hole end face axial linkage clamp, a movable clamping mechanism and a tooth profile forming composite die, wherein the quantitative conveying mechanism is arranged at the top end of the conveying belt, and the movable clamping mechanism is arranged on one side of the top end of the conveying belt. Accordingto the automatic splined hub machining equipment with the function of integrally forming the tooth profile, the tooth profile forming composite die is arranged, so that the problems that in the background art, the efficiency is low and the production cost is high due to common sequential single-tooth machining of existing splined hub material outer tooth spline machining equipment are perfectly solved; due to the design of the die, integral forming and final shaping of tooth bottoms, tooth tops and tooth sides of outer teeth of a splined hub are achieved, it is guaranteed that the dimensionalprecision of a workpiece meets the requirement after extrusion forming through uniform distribution of rolling components and release frames located in inner cavities of two layers of annular supports, and the applicability is higher.

Description

technical field [0001] The invention relates to the technical field of automobile parts production, in particular to an automatic spline hub processing equipment with the function of integrally forming tooth shapes. Background technique [0002] The automatic transmission is a key part of the car, and the spline hub in the transmission clutch is a key part of the transmission. Generally, the spline hub of the automatic transmission clutch of a car is shaped like a cylinder with a bottom surface, and there are teeth on the cylinder surface. The spline hub is the hub connected by the spline shaft. The spline shaft is a kind of mechanical transmission. It has the same function as the flat key, semi-circular key and oblique key. They all transmit mechanical torque. The rotating parts on the shaft also have corresponding keyways, which can keep rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears, etc....

AI Technical Summary

Problems solved by technology

[0003] The existing spline hub tooth profile processing equipment, the common problems are: the current general forming method of the spline hub tooth profile of the automatic transmission clutch of the automobile is rolling forming on a special rolling machine. In the traditional manufacturing process, it is common to place the blank On the rotatable and toothed main shaft of special equipment, the rolling wheels on both sides roll a single tooth shape one by one, then the main shaft rotates for circumferential indexing, and then rolls the next tooth. It can be seen that this method is a single tooth Processing one by one, all tooth shapes need to be processed sequentially, so the processing time of a single piece is long and the efficiency is low, and this method must be processed by a special rolling machine, the processing equipment is expensive, and the processing cost is high
