Machining tool for steel-inlaid guide rail shaped like Chinese character Shan

Abstract

The invention discloses a machining tool for a steel-inlaid guide rail shaped like a Chinese character Shan. The section of the tool is of a polygonal structure; the polygonal structure comprises a first mounting surface, a second mounting surface, a first reference surface and a second reference surface, and the first mounting surface is perpendicular to the second mounting surface; the first reference surface is perpendicular to the second reference surface, the first reference surface and the first mounting surface form a 45-DEG included angle, and the second reference surface and the second mounting surface form a 45-DEG included angle; internal threaded holes which are perpendicular to each other are formed in the first reference surface and the second reference surface; the guide rail shaped like the Chinese character Shan is connected with the internal threaded holes by using bolts after passing through assembling holes formed in the guide rail; the guide rail shaped like the Chinese character Shan is fixedly arranged on the first reference surface and the second reference surface, the first to-be-machined surface of the guide rail shaped like the Chinese character Shan is kept parallel to the second mounting surface, and the second to-be-machined surface of the guide rail shaped like the Chinese character Shan is kept parallel to the first mounting surface. By using the machining tool, the qualified precise guide rail shaped like the Chinese character Shan can be economically and efficiently machined, and batch machining of the precise guide rail shaped like the Chinese character Shan can be realized.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to a processing tool for mountain-shaped steel-inlaid guide rails. Background technique [0002] Steel-inlaid sliding guide rails have 6-8 times higher wear resistance than ordinary cast iron guide rails, high anti-seizing ability, and good precision retention. Therefore, inlaid steel sliding guide rails are widely used in precision machine tools. Inlaid steel sliding guide rails are generally rectangular guide rails, V-shaped, and mountain-shaped guide rails according to the shape of the end surface. Due to the poor guiding performance of the rectangular guide rails, for moving parts with large spans and high requirements for linearity of motion, V-shaped or Mountain guide rail. The length of the mountain-shaped inlaid steel guide rail is generally greater than 1000mm. The precision of the guide rail is high, the processing is difficult, and the processing accuracy is ...
