Rolling-milling combination machine

Abstract

The invention relates to a metal cutting machine tool in the field of mechatronics, in particular to a rolling-milling combination machine. The invention is realized through the following technical schemes: the rolling-milling combination machine comprises a host, an electric cabinet, a hydraulic station and an automatic cooling and chip removal device, wherein the host comprises a workpiece installation assembly, a cutter rest assembly, a cutter rest swing assembly for presetting a cutter, a horizontal axial feeding mechanism for enabling the cutter rest assembly to generate horizontal axialdisplacement, and a radial feeding mechanism for enabling the cutter rest assembly to generate radial displacement; and the cutter rest assembly comprises a cutter swing mechanism, a cutter head switching mechanism and a combination cutter formed by coaxially and integrally connecting a rolling tooth cutter and a milling tooth cutter. The combination machine provided by the invention can be used for processing a taper spline and can finish the tooth removal or tooth splicing processing. Compared with the background art, the combination machine provided by the invention can independently finish the processing of the taper spline of a swing arm shaft.

Description

technical field [0001] The invention relates to metal cutting machine tools and the field of mechatronics, in particular to a hobbing and milling combined machine. Background technique [0002] A kind of taper spline of the steering arm shaft used in automobiles, one tooth or one wide tooth is removed every 90°, that is, as figure 1 As shown, it is necessary to remove or assemble a tooth at the upper, lower, left and right positions of the spline. There are currently three methods for machining the taper splines of the steering arm shaft: 1. Use a spline milling machine to mill out the taper splines first, and then use a milling machine to remove the teeth; 2. Use a single-tool whirlwind cutting; 3. Cut the splines on the gear hobbing machine The teeth are then removed on a milling machine. [0003] The first method and the second method have low processing efficiency, but in the third method, the wear of the carbide blade is large, the blade needs to be replaced frequentl...

AI Technical Summary

Problems solved by technology

[0003] The first method and the second method have low processing efficiency, but in the third method, the wear of the carbide blade is large, the blade needs to be replaced frequently, and the tooth surface finish is poor; however, no matter which method is used, it cannot be completed on the same equipment The processing of the taper spline of the steering arm shaft makes the processing efficiency of this workpiece low, and it is difficult to guarantee the processing accuracy due to the conversion of processing equipment
