Abstract

The invention relates to a numerical control system for a cam lathe, comprising a cam lathe and a numerical control system. The cam lathe is provided with a frame, a gear box, an operating table, X-axis and Z-axis servo motors, a headstock frequency conversion motor and a cutting tool; the numerical control system is provided with Upper computer, PLC, synchronous X-axis, Z-axis motor servo driver and head frame motor inverter driver; use an industrial tablet computer as the upper computer, the upper computer is equipped with cam lathe processing software, the upper computer controls the PLC through RS232 serial port communication, and the PLC accepts The upper computer outputs motion parameters and motion commands, and the PLC uses the electronic cam function module to control the X-axis and the headstock direct-connected encoder to follow up, and controls the tool to complete the turning processing cam. The cam lathe in this numerical control system can be switched between two modes of automatic and manual processing; the numerical control system software of the present invention has a friendly interface and is easy to operate. The cam lathe has a small investment, less tool consumption, good machining accuracy, high efficiency and easy changeover easy.

Description

technical field [0001] The invention relates to a numerical control system of a cam lathe. Specifically, an industrial tablet computer with a cam lathe processing software is used as a host computer, and the host computer controls a PLC with an electronic cam function module to realize the feed of the X axis and the rotary head. A cam lathe numerical control system for processing cam contours in a frame-linkage manner. Background technique [0002] The camshaft, an important part of the internal combustion engine, has two rough machining methods. One is to use a CNC milling machine for milling, and the other is to use a cam lathe with a profile and then use a cam grinder to grind to the set size. The CNC milling machine has high machining accuracy, but the equipment investment is large, and the milling cutter consumes a lot; the profiling cam lathe has a small equipment investment, a small turning tool consumption, and high efficiency, but the poor machining accuracy require...
