Abstract

The invention discloses an RBR-based tool clamp selecting and matching method and a gear hobbing machine tool clamp selecting and matching method. The method comprises the steps of establishing a selecting and matching rule base; extracting related machining task information to serve as a fact condition a for tool matching; taking a conclusion reasoned by a tool matching rule of which the condition part is matched with the fact condition a as a temporary tool set, wherein the intersection of the temporary tool set and the tool resource set is a tool set H; extracting clamping information of the cutter set H and the machining machine tool as a fact condition b for cutter bar matching, and taking a conclusion inferred by a cutter bar matching rule of which the condition part is matched withthe fact condition b as a temporary cutter bar set, wherein the intersection of the temporary cutter bar set and the cutter bar resource set is a cutter bar set B, and updating a cutter set H according to the cutter bar set B; extracting workpiece clamping information as a fact condition c of fixture matching, and taking a conclusion inferred by a fixture matching rule of which the condition partis matched with the fact condition c as a temporary fixture set, wherein the intersection of the temporary clamp set and the clamp resource set is a clamp set F and the cutter clamp set T is equal to{H F}.

Description

technical field

[0001] The invention belongs to the technical field of machining and manufacturing, and in particular relates to a matching method of a tool holder. Background technique

[0002] As a component element of a gear system, gears are widely used and play a key role in mechanical equipment such as wind power generation, aerospace, automobiles and shield machines; the quality of their dynamic characteristics will directly affect the performance of the whole machine . For the processing of gears, gear hobbing is currently the most widely used gear cutting method at home and abroad, and the possession of gear hobbing machines in some countries accounts for about 45% to 50% of the total gear machine tools. Therefore, the hobbing machine tool, as a typical type of manufacturing machine tool, has a significant impact on the manufacturing and processing of gears, especially the reasonable selection of tool holders for gear hobbing machines is of great significance in th...
