Problems solved by technology
[0004] Based on this, it is necessary to focus on the existing machine tool fault troubleshooting teaching mainly in the form of disconnection or button cut-off circuit, etc., during the troubleshooting teaching, the operation volume is relatively large, the teaching efficiency is low, the safety is low, the damage to the equipment is relatively large, and related For the problem of high consumption of materials, provide a machine tool fault troubleshooting teaching system with less operation during troubleshooting teaching, higher teaching efficiency, higher safety, less damage to equipment, and no need to troubleshoot materials

The invention relates to a teaching system for machine tool troubleshooting, which comprises a trouble setting board, a troubleshooting board, a PLC (programmable logic controller) and a plurality of specific relays, wherein the trouble setting board, the troubleshooting board and the plurality of specific relays are electrically connected with the PLC, and the plurality of specific relays are connected to a plurality of specific trouble presetting points in a machine tool circuit respectively. According to the teaching system for machine tool troubleshooting, the plurality of specific relays are connected to the specific trouble presetting points in the machine tool circuit respectively; when the specific trouble presetting point is cut off, a circuit of the specific trouble presetting point is disconnected, and setting of a trouble point is completed; and when the specific trouble presetting point is connected, the circuit of the specific trouble presetting point is connected, and troubleshooting of the trouble point is completed. A teacher can randomly select and set the trouble point through the trouble setting board, and students carry out troubleshooting through the troubleshooting board, the operation amount in troubleshooting teaching is small, the teaching efficiency is high, and troubleshooting materials are not required. Wires are not contacted directly in the whole troubleshooting process, thereby being high in security, and having small damages for equipment.
Description
technical field [0001] The invention relates to the field of troubleshooting teaching, in particular to a machine tool troubleshooting teaching system. Background technique [0002] A machine tool refers to a machine that manufactures a machine, also known as a machine tool or a tool machine, and is customarily referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: In addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc., but for parts with high precision requirements and fine surface roughness requirements, they generally need to be processed. The final machining is done by cutting on the machine tool. Machine tools play an important role in the modernization of the national economy. In order to adapt to the adjustment and optimization of the industry structure, the requireme...
