Machine tool for repairing surface of die

Abstract

The invention discloses a machine tool for repairing the surface of a die. The machine tool comprises a positioning frame mechanism and a finishing head mechanism, the positioning frame mechanism has six spatial degrees of freedom, each movable joint is provided with a graduated scale, the finishing head mechanism adopts five-gear variable-speed transmission, is fastened and mounted at the tail end of the positioning frame mechanism and is used for repairing the surface of the die, the finishing head mechanism adopts a gear with a small transmission ratio during idle stroke, so that the moving time of a grinding head can be shortened, the finishing head mechanism adopts a gear with a large transmission ratio during finishing of the surface of the die, the machining quality of the surface of the die can be improved, the gear is replaced by changing the position of a shifting rod, a worm and gear transmission structure is adopted in the finishing head mechanism, so that transmission is stable, a self-locking function is further achieved, so that the counter-acting force of the surface of the die to the grinding head cannot react on a hand wheel through a transmission mechanism, and the surface of the die can be stably finishing-machined by rotating the hand wheel.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a machine tool for repairing the surface of a mold. Background technique [0002] Molds play an extremely important role in modern industry, and the quality of molds directly determines the quality of products. my country's mold industry has developed rapidly in recent years and has become one of the top three mold producing countries in the world. However, there is still a big gap between my country's mold industry and foreign advanced mold production levels, mainly in the long manufacturing cycle, low manufacturing precision, and mold production. In terms of short life, the problem of short mold life is particularly prominent, which directly leads to the waste of resources and the increase of production costs. Therefore, repair and reuse the failed molds to prolong the use time of the molds, thereby recovering unnecessary losses in production , will greatly promote the devel...
