High-precision grinding process of small-modulus skiving cutter

Abstract

The invention relates to the technical field of skiving cutter manufacturing, in particular to a high-precision grinding process of a small-modulus skiving cutter. The process comprises the steps of grinding equipment selection, grinding wheel selection, grinding wheel correction, workpiece installation, grinding path planning, grinding programming and tooth-shaped molded line point grinding, wherein the tooth-shaped molded line point grinding comprises first grinding path planning and second grinding path planning, in the first grinding path planning, a plurality of radial grinding molded lines of a tooth-shaped surface are arranged, every two adjacent radial grinding molded lines are spaced by a certain molded line axial distance, and during grinding, a point grinding wheel is pushed andperforms grinding one by one along the radial grinding molded lines of the tooth-shaped surface of the small-modulus skiving cutter from front to back and from left to right; and in the second grinding path planning, a plurality of axial grinding molded lines of the tooth-shaped surface are arranged, every two adjacent axial grinding molded lines are spaced by a certain molded line radial distance, and during grinding, the point grinding wheel is pushed and performs grinding one by one along the axial grinding molded lines of the tooth-shaped surface of the small-modulus skiving cutter from the tooth crest to the tooth bottom. According to the process, high-precision machining of the small-modulus skiving cutter is realized.

Description

technical field [0001] The invention relates to the technical field of hob inserting knife manufacturing, in particular to a high-precision grinding process for small modulus hob inserting knives. Background technique [0002] Small modulus hobbing cutter (hobbing cutter is also known as skiving cutter) is a continuous displacement gear with rake angle and rear angle. It has different displacement coefficients, top circle diameters and Tooth thickness, the theoretical value of the gear with the same modulus can only be found on the original cross-section where the coefficient of variation is zero. Driven by the hob shaping machine with small modulus, the cutting movement of the hob cutter and the meshing motion of the cut gear form the tooth surface of the envelope surface, so the cutting movement of the hob cutter and the contact with the gear Mesh generative motion accuracy determines the accuracy of the tooth envelope surface. It can be seen from this that in order to i...
