Method for processing camshaft spline of automotive brake and device therefor

Abstract

The invention relates to a method for processing a camshaft spline of an automotive brake and a device therefor. The device comprises a squeeze roller I, a squeeze roller II, a squeeze roller base, a limit device, an adjusting device, a driving mechanism, a squeeze roller position adjusting mechanism, a frame and a wear-resisting bearing, wherein the squeeze roller base is provided with the limit device and the adjusting device and is also provided with the squeeze roller position adjusting mechanism; the squeeze roller I and the squeeze roller II are connected with the driving mechanism; and the squeeze roller base, the driving mechanism and the wear-resisting bearing are arranged on the frame. By adopting the two squeeze rollers for rolling, the tooth shape of the processed spline is consistent, and the surface density degree after processing is obviously strengthened, thereby greatly improving the quality of the processed product. As the blank is preheated before extrusion processing, the extrusion is carried out under certain temperature, so that the extrusion is easy, and the performance of the processed product is reliable. The extrusion process is adopted for processing, so as to improve the working efficiency greatly.

Description

technical field [0001] The invention relates to a processing method of an automobile part, in particular to a processing device for a spline of an automobile brake camshaft. Background technique [0002] After retrieving relevant patent documents, a kind of processing equipment for camshaft splines of automobile brakes with the same structure as the present invention has not been retrieved yet. The splines of the existing automobile camshafts are generally milled on a special milling machine with a spline milling cutter. Due to the processing method, the processed splines have serious scale-like tool marks, and the burrs at the cutting parts are relatively serious. Obviously, the relatively poor surface roughness and other reasons, coupled with the adjustment of the position of the milling cutter and the relative position of the workpiece, are prone to offset during the machining process, resulting in a large deviation of the spline angle. And because the end of the spline ...

The splines of the existing automobile camshafts are generally milled on a special milling machine with a spline milling cutter. Due to the processing method, the processed splines have serious scale-like tool marks, and the burrs at the cutting parts are relatively serious. Obviously, the surface roughness is relatively poor, coupled with the adjustment of the position of the milling cutter and the relative position of the workpiece, it is easy to shift during the processing, resulting in a large deviation of the spline angle

And because the end of the spline is milled by the milling cutter in the length direction, a long excessive arc should appear, which may easily cause improper assembly
