Tool holder structure for dry cutting gear hobbing machine

Abstract

The invention discloses a tool carrier structure of a dry cutting gear hobbing machine. The tool carrier structure comprises a tool carrier base and a hob arbor. A large slide base, a small slide base, a first linear guide rail and a second linear guide rail are arranged on the tool carrier base. One end of the hob arbor is arranged on the large slide base, and the other end of the hob arbor is arranged on the small slide base. The first linear guide rail and the second linear guide rail are arranged in parallel. At least two guide rail slide blocks I are arranged on the first linear guide rail. At least two guide rail slide blocks II are arranged on the second linear guide rail. The upper side of the large slide base and the upper side of the small slide base are arranged on the first linear guide rail through different guide rail slide blocks I. The lower side of the large slide base and the lower side of the small slide base are arranged on the second linear guide rail through different guide rail slide blocks II. The large slide base and the small slide base can be conveniently combined for machining, and therefore the coaxiality requirement of a main shaft hole of the large slide base and a bearing hole of the small slide base is ensured, and rigidity and precision stability of a main shaft system are ensured.

Description

technical field [0001] The invention relates to a tool holder structure of a gear hobbing machine, in particular to a tool holder structure of a dry cutting gear hobbing machine. Background technique [0002] The existing gear hobbing machine turrets are cumbersome to assemble and need to be adjusted repeatedly to meet the performance requirements of the spindle system. Therefore, the assembly accuracy is not high, and it is difficult to ensure the rigidity and accuracy stability of the spindle system, thereby affecting the hobbing accuracy and rolling life. , the slide plate of the tool holder is easy to move, thereby reducing the processing quality of the workpiece. Contents of the invention [0003] In view of this, the object of the present invention is to provide a tool holder structure for a dry cutting gear hobbing machine, which can overcome the above-mentioned defects of the prior art, has high assembly accuracy and can effectively prevent the sliding plate of the...
