Inverted type knife rest component

Abstract

An inverted type knife rest component comprises a vertical column plate, a central chuck arranged on the vertical column plate, an electric main shaft with a main shaft chuck, a knife rest plate and a knife changing sliding plate. The electric main shaft is arranged on one side of the vertical column plate, the knife rest plate and the knife changing sliding plate are arranged on the other side of the vertical column plate, the knife rest plate is arranged on the knife changing sliding plate, the knife changing sliding plate is arranged on the vertical column plate, the knife rest plate is arranged in a cavity formed between the knife changing sliding plate and the vertical column plate and is closer to the vertical column plate than the knife changing sliding plate, a plurality of knife bits are arranged on the knife rest plate, a material part penetrates into the central chuck in the vertical column plate through the main shaft chuck, and the end of the material part is close to the knife rest plate. Compared with the prior art, the structure of an existing knife rest component is changed, the distance between the main shaft chuck and the lower end of the knife rest plate is shortened as far as possible, the length of an abandoned material part is shortened when the material part is processed, and production cost is lowered to the largest extent.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a reverse tool rest assembly. Background technique [0002] Walking core machine--the full name is walking core CNC lathe, and it can also be called spindle box mobile CNC automatic lathe, economical turning and milling compound machine tool or slitting lathe. It belongs to precision processing equipment, which can complete compound processing such as turning, milling, drilling, boring, tapping and engraving at the same time. It is mainly used for batch processing of precision hardware and shaft special-shaped non-standard parts. The machine tool first originated in Germany and Switzerland. It was mainly used for precision machining of military equipment in the early stage. With the continuous development and expansion of industrialization, it was gradually applied to the processing of civilian products due to the urgent needs of the market; similar machine tools in Japan and S...
