Machine tool used for machining gear shaving cutter chip pocket

Abstract

A machine tool used for machining a gear shaving cutter chip pocket is composed of a tool body, a middle tool body, a stand column, a sliding base, a cutter rest assembly, a dividing head, a transverse sliding platform, a digital control system and a hydraulic system. The machine tool is characterized in that the tool body is fixed to a foundation, the middle tool body and the transverse sliding platform are arranged at the two ends of the upper side of the tool body, a horizontal moving mechanism enabling the middle tool body to move horizontally is arranged between the middle tool body and the tool body, the middle tool body is provided with the stand column, and the side face of the stand column is provided with the sliding base provided with the cutter rest assembly; the transverse sliding platform is provided with the dividing head, and the position of the dividing head corresponds to that of the cutter rest assembly in the vertical direction; the sliding base is provided with a main driving mechanism, an any spiral angle compensation mechanism, a micro cutter relieving mechanism and a stoke length automatic regulating mechanism. The machine tool achieves digital control, can achieve an automatic tool setting function, is convenient to regulate, and lowers labor intensity of workers.

Description

technical field [0001] The invention relates to a machine tool for machining chip grooves of gear shaving cutters, in particular to a fully digitally controlled machine tool for processing chip grooves of gear shaving cutters with functions of automatic tool setting and arbitrary helix angle compensation. Background technique [0002] At present, most of the equipment used by domestic tool manufacturers to process the chip pockets of shaving cutters is still the equipment modified by the slotting machine. The main movement of cutting up and down on the slotting machine is used, and an externally purchased dividing head is added. In most cases, this kind of equipment can only process Axial gear shaving cutters cannot process radial gear shaving cutters, and the processed small grooves cannot form dislocation distribution on each tooth surface, and the main movement efficiency of the slotting machine is low, and most of the indexing heads are mechanical indexing heads, which re...

[0002] At present, most of the equipment used by domestic tool manufacturers to process the chip pockets of shaving cutters is still the equipment modified by the slotting machine. The main movement of cutting up and down on the slotting machine is used, and an externally purchased dividing head is added. In most cases, this kind of equipment can only process Axial gear shaving cutters cannot process radial gear shaving cutters, and the processed small grooves cannot form dislocation distribution on each tooth surface, and the main movement efficiency of the slotting machine is low, and most of the indexing heads are mechanical indexing heads, which require manual operation Razor splitting action

Foreign Gleason and Italy SU have developed special machine tools for shaving cutter comb groove processing, but because of its high price and the export of this equipment to China is now restricted, domestic tool manufacturers can only rely on radial shaving cutters for processing radial shaving cutters Most of the second-hand combing machines imported from abroad are mechanical traditional machine tools, with low processing efficiency, unstable processing accuracy, and frequent failures of machine tools. Therefore, many domestic customers hope that we can develop a more flexible and higher processing efficiency. , Easy-to-operate machine tools to replace foreign imported equipment
