Electric system of combined copying lathe machine for simultaneously turning and milling internal and external circles of piston ring

Abstract

The invention discloses an electric system of a combined copying lathe machine for simultaneously turning and milling internal and external circles of a piston ring. The electric system comprises an embedded type integrated industrial personal computer, a programmable logic controller (PLC), a first frequency converter, a second frequency converter and a servo amplifier. In the machine tool electric system disclosed by the invention, a touch screen (namely the embedded type integrated industrial personal computer) is taken as a center, two communication interfaces of the PLC are fully utilized at the same time to structure two communication links, wherein the touch screen, the PLC and the servo amplifier constitute the first communication link, and the touch screen, the first frequency converter and the second frequency converter constitute the second communication link, so that the frequency converters and the servo amplifier are prevented from being connected onto the same communication link skillfully and the contradiction generated because different communication protocols cannot be operated is avoided.

Description

technical field [0001] The invention relates to a combined turning and milling machine tool for simultaneous profiling of inner and outer circles of piston rings, in particular to an electrical system of a combined turning and milling machine tool for simultaneous profiling of inner and outer circles of piston rings. Background technique [0002] The special machine for piston ring processing is a special machine tool for the internal combustion engine manufacturing industry. Simultaneous profiling of the inner and outer circles of piston rings (hereinafter referred to as the profiling car) adopts simultaneous profiling of the inner and outer circles, and completes the machining in one pass, which better realizes the elastic force distribution of piston rings with different design requirements and greatly shortens the process. process, improving production efficiency. The residual stress in the workpiece is avoided, and it is easier to control the quality. [0003] At pres...

Problems solved by technology

[0004] The object of the present invention is to propose an electrical system for the simultaneous profiling of the inner and outer circles of the piston ring turning and milling combination machine tool. This system overcomes the low control precision of the existing electrical system through the setting of the operating speed of the external input potentiometer, and the complicated operation buttons on the console. Unintuitive, bulky, which affects the lack of operational efficiency of workers
