Numerical control tooth grinder for spiral bevel gear

Abstract

The invention relates to a numerical control curve-tooth bevel gear grinder, which comprises a lathe bed, and is characterized by also comprising an upright post, a grinding wheel main shaft box, a workpiece main shaft box, an electric turntable, a grinding wheel correcting mechanism and a numerical control system. The lathe bed in the horizontal direction is provided with linear guide rails vertical to each other, the upright post and a bed saddle are arranged on the linear guide rails respectively, and an upright post automatic moving mechanism is arranged between the bottom of the upright post and the lathe bed; one lateral surface of the upright post is provided with the linear guide rail and the grinding wheel main shaft box, and the same side of the upright posts close to the top is provided with a moving mechanism for driving the grinding wheel main shaft box to move; and the bed saddle is provided with the electric turntable which is provided with the workpiece main shaft box on which the grinding wheel correcting mechanism is arranged. The numerical control curve-tooth bevel gear grinder has the advantages that the grinder simplifies the prior mechanical transmission, shortens adjusting time of a machine tool, has compact and reasonable structure, accurate processing with high accuracy, high automation degree to remarkably improve processing efficiency, and has low manufacturing cost to relieve economic burden of enterprises.

Description

technical field [0001] The invention belongs to the technical field of gear machine tools, in particular to a numerically controlled spiral bevel gear grinding machine. Background technique [0002] The CNC spiral bevel gear grinding machine is used for high-speed and accurate grinding of spiral bevel gears. Its purpose is to correct the deformation of the gear after heat treatment, improve the precision and smoothness of the tooth surface, and meet the requirements of stable transmission, lower noise and higher precision. The bevel gear grinding machine tool in the prior art mainly includes: bed, three numerically controlled axes: cradle (X axis), workpiece (Y axis), bed saddle (Z axis), adopts AC frequency conversion speed regulation The grinding wheel spindle (S axis) and electrical control part; the machine tool adopts the frequency conversion motor as the main driving force source, the cradle and the workpiece spindle are driven by the precision worm gear pair driven by...
