Special purpose machine tool for machining inner ports of barrel-type fixed-length parts

Abstract

The invention relates to a special purpose machine tool for machining inner ports of barrel-type fixed-length parts. The special purpose machine tool comprises a machine frame and a power distribution control box. The machine frame is provided with a machining plate. The machining plate is provided with machining devices matched with each other and a material loading device matched with the products. Each machining device comprises a feeding base arranged on the machining plate. Each feeding base is connected with a feeding device and provided with a machining motor and machining rotors, and the machining motor and the machining rotors are matched with one another. Each machining rotor is uniformly provided with three sets of machining knife holders. Every three sets of machining knife holders are provided with three sets of cutting knives matched with the inner port of the corresponding product, and the three sets of cutting knives are different in both turning radius and turning depth. According to the special purpose machine tool for machining the inner ports of the barrel-type fixed-length parts, each machining rotor is uniformly provided with the three sets of machining knife holders, every three sets of machining knife holders are provided with three sets of cutting knives matched with one another, and the three sets of cutting knives are different in turning radius and turning depth; and thus, machining of three step openings of the inner port of each barrel-type part can be completed in one time, the machining efficiency of the inner ports of the barrel-type parts is greatly improved, and the machining time is shortened.

Description

technical field [0001] The invention relates to the field of machine tool equipment, in particular to a special machine tool for processing the inner ports of round-through fixed-length parts. Background technique [0002] There is a type of parts that are cylindrical, such as metal pipes and plastic pipes. In order to achieve a good fit during the assembly process, the inner ports need to be turned. Step mouth, and the processing of the inner port is mostly using cutting machine tools. [0003] Most of the inner ports of existing cylindrical products are processed by ordinary lathes, which require three turning processes, either by changing the tool for three turnings, or by changing three lathes for three turnings. It takes a lot of turning processing time, and the processing efficiency is low. Contents of the invention [0004] The object of the present invention is to provide a special machine tool for processing the inner ports of cylindrical fixed-length parts. Thr...
