Spline shaft machining process

Abstract

The invention discloses a spline shaft machining technology in the technical field of machining. The spline shaft machining technology comprises the steps that 1, a cylinder is subjected to rough turning and finish turning to form a shaft body; 2, a drilling machine is used for drilling the shaft body, and then a boring machine is used for boring a hole in the shaft body; 3, a plurality of spline grooves are cut in the hole in the shaft body through linear cutting; and 4, grinding equipment is used for grinding the inner walls of the spline grooves, wherein the grinding equipment comprises a base, a positioning unit, a grinding unit and a rotating unit. Compared with the prior art, the spline shaft machining process has the beneficial effects that the inner walls of the spline grooves are ground through the grinding device, so that control over the surface roughness of the spline grooves can be guaranteed on the premise that the cost is reduced through common equipment; and in addition, an adjusting screw is arranged to be screwed on a mounting head in a threaded manner so as to drive a hinge rod to swing, and then the grinding depth of a grinding block is adjusted, so that the spline grooves with different depths can be ground.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a spline shaft processing technology. Background technique [0002] The spline shaft is a kind of mechanical transmission. The function of the flat key, semicircular key and wedge key is the same. They all transmit mechanical torque. Rotate synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears, etc. [0003] The current spline shafts are usually processed by lathes, boring machines, wire cutting, etc. When these devices are processed, the spline grooves on the spline shafts will have surface roughness defects, which will affect the spline grooves. Accuracy affects usage. [0004] Based on this, the present invention designs a spline shaft processing technology to solve the above problems. Contents of the invention [0005] The purpose of the present invention is to provide a spline shaft proc...
