Abstract

The invention discloses a transmission shaft spline shaft metal processing technique. The processing technique comprises the following steps of: performing thermal refining by using a thermal refining automatic line; milling a small end surface by using a milling and drilling machine, and drilling centre bores at two ends; performing fine turning by using a numerically controlled lathe; milling a spline by using a numerical control spline milling machine; removing front points and burr; and performing mid frequency induction hardening by using a mid frequency induction hardening machine. The processing technique can guarantee the part accuracy to the maximum extent, eliminate various errors caused by position reference conversion, shortens the whole metal processing flow, reduce a large number of manpower and material resources, greatly reduce the processing cost, reduce the labor intensity, improve the working efficiency, and save processing cost.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a gold processing technology of a transmission shaft spline shaft. Background technique [0002] The use requirements of the automobile transmission shaft assembly are quite special. It needs to rotate at a high speed when transmitting torque, and as people's requirements for the humanization of automobile design and the comfort of automobile passengers are getting higher and higher, the dynamics of the transmission shaft assembly The requirements for balance accuracy and residual unbalance value are also getting higher and higher. The existing transmission shaft head is processed by ordinary stand-alone equipment, and the processing process has a total of fifteen processes, which are as follows: [0003] ⑴, use pit furnace for normalizing treatment; [0004] ⑵. Use a special fixture to clamp it to the drilling and milling machine, mill the two ends, a...
