A machine tool for machining chip pockets of shaving cutters

Abstract

A machine tool for processing chip pockets of gear shaving cutters, which includes a bed, a middle bed, a column, a sliding seat, a tool holder assembly, an indexing head, a transverse slide, and a numerical control system and a hydraulic system. The bed is fixed to the foundation, the middle bed and the horizontal sliding platform are arranged at both ends of the upper side of the bed, and a horizontal movement mechanism is arranged between the middle bed and the bed to move the middle bed horizontally. A column is provided, a sliding seat is provided on the side of the column, and a tool holder body assembly is arranged on the sliding seat; an indexing head is arranged on the horizontal sliding table, and the upper and lower positions of the indexing head and the tool holder body assembly correspond; Drive mechanism, arbitrary helix angle compensation mechanism, micro-knives mechanism and stroke length automatic adjustment mechanism. Each motion of the present invention realizes digital control, can realize the function of automatic tool setting, the adjustment of the machine tool is convenient, and the labor intensity of workers is reduced.

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
