Problems solved by technology

[0002] At present, in the existing technology, due to the limitation of the machining range of the machine tool, the machining of short gear shaft milling and grinding has always been to lengthen the process at one end of the workpiece, and then milling and grinding
After milling and grinding the teeth, the lengthening part is cut off, and each workpiece is lengthened and then cut off, which wastes a lot of materials and increases the cost of the company
Therefore, this processing method can no longer meet the current requirements of high efficiency and low cost.

Embodiment Construction

[0011] Depend on Figure 1~3 It can be seen that the processing of the short gear shaft is completed according to the following steps:

[0012] Step 1, calculate blanking size, and carry out blank blanking and heat treatment;

[0013] Step 2, rough and finish turning the workpiece;

[0014] Step 3, initial grinding of outer circles A and B;

[0015] Step 4, milling the key grooves at both ends of the workpiece;

[0016] Step 5. Align two points on the outer circle of A and B, and the runout is within 0.05mm. Roughly and finely mill the teeth to ensure the common normal line size required by the process;

[0017] Step 6, the middle outer circle is protected against seepage, and the gear is carburized and quenched;

[0018] Step 7, the outer circle and rounded corners in the middle of the second finishing car;

[0019] Step 8, finely grind the outer circles of A and B at both ends, the middle outer circle and the addendum circle, and grind the end faces;

[0020] Step 9: A...

Abstract

The invention relates to the technical field of gear milling and gear grinding in the machinery manufacturing industry, in particular to a high-efficiency machining method for a short gear shaft. In the existing processing methods, most short gear shaft workpieces need to be ground after tooth milling, but in the process of tooth milling and gear grinding, due to the short workpiece, it cannot be directly processed due to the limitation of the machining range of the machine tool. The workpiece must be lengthened to a position where the radius of the hob or the grinding wheel can be released before the normal processing of the workpiece can be carried out. After the workpiece is processed, the lengthened part is removed, which wastes both man-hours and materials. The invention provides a high-efficiency machining method for a short gear shaft, which thoroughly solves the above-mentioned problems of waste of materials and man-hours. The method utilizes the extended part to process two parts at a time, which not only reduces the cost, but also improves the production efficiency.

technical field [0001] The invention relates to the technical field of milling and grinding of short gear shafts in the machinery manufacturing industry, in particular to a high-efficiency processing method for short gear shafts. Background technique [0002] At present, in the prior art, the milling and grinding of the short gear shaft is limited by the machining range of the machine tool, and the lengthening process has always been carried out at one end of the workpiece, and then the milling and grinding are performed. After milling and grinding the teeth, the lengthened part is cut off, and each workpiece is lengthened and then cut off, which wastes a lot of materials and increases the company's cost. Therefore, this processing method can no longer meet the current requirements of high efficiency and low cost. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a high-efficiency machining method for a short ...
