Machine tool for die surface repair

Abstract

The invention discloses a machine tool for die surface repair. The machine tool comprises a positioning frame mechanism and a trimming head mechanism, the positioning frame mechanism has six spatial degrees of freedom, each movable joint is provided with a graduated scale, the trimming head mechanism can conduct precise spatial positioning, and the trimming head mechanism is installed at the tail end of the positioning frame mechanism in a fastened manner and is used for repairing the surface of a die; the trimming head mechanism has the functions of fast and slow gears, the fast gear is adopted during idle stroke, and therefore the moving time of a grinding head is shortened; the slow gear is adopted during trimming of the surface of the die, so that the machining quality of the surface of the die is improved, and the fast and slow gear switching is achieved by changing the position of a shifting rod; during the slow gear, a transmission structure is a planetary gear train, and during a fast gear, the transmission structure is an ordinary gear train; and a thread pair transmission structure with a self-locking property is adopted in the trimming head mechanism, so that the counter-acting force of the surface of the die on the grinding head cannot act on a hand wheel through the transmission mechanism, and the surface of the die can be stably trimmed and 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 mold surface repair. 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 development of in...

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 development of industry and the national economy, and have significant economic benefits and social significance
