Problems solved by technology

However, limited by the capacity of broaching machine tools, the current broaching method can only be used for processing small-diameter internal gears, and large-diameter internal gears are still processed by gear shaping. Not only the processing efficiency is low, but the processing process The impact of vibration and noise is also relatively large

Abstract

The invention relates to a large-diameter internal gear broaching machining device which comprises an oil cylinder, a following support, a cutter holder, a combined broach, a working table supporting base, a working table lifting mechanism, a rotating working table and a lathe bed. The oil cylinder is connected with the cutter holder through a piston pull rod. The piston pull rod is fixed to the following support. The combined broach is connected with the cutter holder. The working table lifting mechanism and the rotating working table are arranged on the working table supporting base. The rotating working table is connected with the working table lifting mechanism. The following support is installed on a guide rail of the lathe bed. The working table supporting base is fixed to the lathe bed. According to the large-diameter internal gear broaching machining device, a large-diameter gear can be machined in a broached mode, the problem that due to restriction of factors like the ability of a broaching machine, teeth of the large-diameter internal gear can not be machined in a broached mode is solved, the machining efficiency of the large-diameter internal gear can be improved greatly, the manufacturing cost of a broaching cutter can be greatly reduced, the number of times of cutter grinding of the cutter is increased, the service life of the cutter is prolonged, and the requirement for machining internal gears with different diameters in the broached mode can be met.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a large-diameter internal gear broaching device. Background technique [0002] In the field of machining technology, the broaching method is used to process the inner surface of mechanical parts such as internal gears, which not only has high processing efficiency, but also has low vibration and noise. However, limited by the capacity of broaching machine tools, the current broaching method can only be used to process internal gears with small diameters. Internal gears with large diameters are still processed by gear shaping. Not only the processing efficiency is low, but the processing process The impact of vibration and noise is also relatively large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an internal gear broaching device suitable for broaching large-diameter internal gears according to...
