Problems solved by technology

[0003] The technical problem solved by the present invention: in the process of hobbing machine processing worm and gear shaft parts, the hob and the workpiece are arranged side by side, the hob is installed on the tool holder, driven by the main shaft of the tool holder to rotate, and the workpiece is fixed by the clamp and the tailstock ; Because the tailstock in the prior art is installed on the tail end of the workbench, it is in parallel with the knife rest, so that the knife rest and the tailstock are crowded with each other, which makes it difficult for the operator to move the knife rest or the tailstock, especially When the operator maintains and disassembles the tool rest or tailstock; in addition, the side-by-side tool rest and tailstock occupy a relatively large space of the machine tool, which is not conducive to the simplification of the machine tool structure

Abstract

The invention discloses a horizontal CNC gear hobbing machine which comprises a lathe bed, a spindle box, a workpiece holder, a tailstock, a hob rest, a hob, a workbench, a cross beam and an oblique support. The spindle box is mounted on the lathe bed, the spindle box comprises a workpiece spindle, and the workpiece holder is mounted on the workpiece spindle. The hob rest is mounted on the workbench, the workbench is mounted on the lathe bed, and the hob is mounted on the hob rest. One end of the cross beam is mounted on the top of the spindle box, the other end of the cross beam is mounted on the oblique support, and the oblique support is mounted on the lathe bed. The tailstock is inversely hung on a trapezoidal guide rail of the cross beam. According to the technical scheme, the tailstock breaks the routine to be mounted on the cross beam and is in a suspension mode, the tailstock and the hob rest are arranged up and down, and a condition is created for guaranteeing wide-range adjustment of the hob rest which is horizontally arranged below; besides, the horizontal mode of a main machine body of the gear hobbing machine is arrayed into a gantry mode, due to the up-down arrangement of the hob rest and the tailstock, the occupied space of a machine tool is saved, and thus the machine tool structure can be simplified easily.

Description

Technical field: [0001] The invention relates to gear hobbing machine equipment, in particular to a horizontal numerically controlled gear hobbing machine. Background technique: [0002] It is generally known that the tailstock of the machine tool is slidably installed on the tail end of the workbench, and the top of the tailstock pushes into the thimble hole on the end surface of the workpiece to stabilize the workpiece, especially the shaft parts. As a classification of machine tools, gear hobbing machines usually use the tailstock at the end of the workbench to stabilize the workpiece fixed by the fixture when processing worm and gear shaft parts. Invention content: [0003] The technical problem solved by the present invention: in the process of hobbing machine processing worm and gear shaft parts, the hob and the workpiece are arranged side by side, the hob is installed on the tool holder, driven by the main shaft of the tool holder to rotate, and the workpiece is fix...
