Method for machining spline of large workpiece

Abstract

The invention relates to the field of machining, in particular to a method for machining a spline of a large workpiece. The method for machining the spline of the large workpiece comprises the following steps of clamping, wherein the workpiece is placed on V-shaped iron of a locating and clamping device, a dividing device and a rotating device are arranged, and the workpiece is corrected; correcting, wherein, the highest points of the outer circles of two fixed pins on the dividing devices in the horizontal diameter direction are made to be equal in height, a groove tries to be milled through an end mill on a side milling head after primary mill setting, the height of the lower side face of the tooth groove is detected, a pressing plate is loosened, the workpiece is rotated by 180 degrees, the outer circles of the two fixed pins are corrected to be equal in height at this moment, the height of the lower side face of the machined tooth groove is detected and recorded, if the height data of two times are different, the side milling head is adjusted to be half of the difference value, and the workpiece is compressed after being adjusted. The machining process is simple, the machining quality of the workpiece can be guaranteed, production efficiency can be improved, and production cost can be saved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a spline processing method for large workpieces. Background technique [0002] The spline connection is connected with each other by using a plurality of spline teeth evenly distributed on the circumference of the shaft and the hub hole to transmit the load. Compared with the spline connection, it has a higher bearing capacity, better centering and guiding, and weakens the shaft. Small size, suitable for connections that transmit medium or large loads and require high centering, and are widely used in mechanical equipment, especially in metallurgy, lifting and other heavy equipment, spline connections are commonly used. [0003] Splines are usually processed on spline milling machines, spline grinders, or gear hobbing machines. Due to the high requirements for matching accuracy and coaxiality, the processing is difficult, and the processing of splines for large workpieces is ...

Problems solved by technology

[0003] Splines are usually processed on spline milling machines, spline grinders, or gear hobbing machines. Due to the high requirements for matching accuracy and coaxiality, the processing is difficult, and the processing of splines for large workpieces is limited by the processing range of special machine tools. Restricted, processing is more difficult
