Inner-cone spline broaching machine tool

Abstract

The invention discloses an inner-cone spline broaching machine tool, which comprises a base, a broaching tool, a sliding plate, a cutter relieving cylinder assembly, a working device and a driving device. The base is arranged on a machine tool body and is provided with a guiding seat thereon; one end of the broaching tool extends into the machine tool body, and the broaching tool is connected with a stretching cylinder in the machine tool body and can be vertically and slidably arranged on the guiding seat; the sliding plate is sleeved on the guiding seat and is slidably arranged on the base;the cutter relieving cylinder assembly is arranged on the base, and an extending end of the cutter relieving cylinder assembly is connected with the sliding plate; the working device is arranged on the sliding plate and is used for fixing inner-cone splines; and the driving device is arranged on the sliding plate and is used for driving the working device to rotate one indexing unit each time. According to the inner-cone spline broaching machine tool disclosed by the invention, the inner-cone splines are machined by a broaching tool in a broaching manner, the precision by adopting the broaching tool is higher than the precision by adopting gear planning, and the efficiency by adopting the broaching tool is higher the efficiency by adopting the gear shaping and the gear planning; the working device carries out operations, such as automatic indexing, automatic broaching tool feeding, retracting and the like, by the driving device, thus the indexing operation is uniform and reliable, andthe degree of automation is high; and the inner-cone spline broaching machine tool disclosed by the invention is convenient to be detached, and can carry out multiple specifications of inner-cone spline operations by replacing the working device.

Description

technical field [0001] The invention relates to the technical field of internal cone spline processing, and more specifically relates to an internal cone spline broaching machine tool. Background technique [0002] The spline connection is composed of internal splines and external splines. The internal and external splines are multi-tooth parts. The splines on the surface of the inner cylinder are internal splines, and the splines on the surface of the external cylinder are external splines. Obviously, the spline connection is the numerical development of the flat key connection. [0003] Due to the difference in structure and manufacturing process, compared with the flat key connection, the spline connection has the following characteristics in terms of strength, technology and use: because more teeth and grooves are directly and uniformly made on the shaft and the hub hole, Therefore, the coupling force is relatively uniform; because the groove is shallow, the stress conc...

AI Technical Summary

Problems solved by technology

[0004] Due to the unique structure of the cone spline, its manufacturing process is more complicated, and sometimes special equipment is required, and the cost is high, especially the internal cone spline

At present, the internal cone splines with large diameters are generally processed by gear shaping machines or single-tooth planing on planers with forming knives in China. However, the efficiency of gear shaping machines is low, and planer processing is not only inefficient, but also of poor quality
