Machine tool electrical line fault handling method
1 direct observation method
The direct observation method refers to a method of using visual and tactile sensation to find out the cause of the fault in the electrical circuit system of the machine tool and solve the fault in time. Direct observation is one of the most common methods in the troubleshooting of machine tool electrical lines. This method is highly efficient in dealing with simple machine tool failures. When there is a fault in the electrical circuit system of the machine tool, sparks, odors or local smoke may sometimes occur. In the actual inspection process, the maintenance personnel can make good use of the visual, tactile and olfactory functions, so that the machine electrical circuit can be used. The fault location is found in the system, and the fault is processed and repaired in time.
2 resistance maintenance method
Assume that the 203 line on the KM4 is loose in the main circuit, and the fault point can be found by the electric resistance method. During the inspection, the RX10 resistance file in the multimeter can be used to place a watch bar at V11 point, the other watch bar gradually moves downward from 201 points, and the KM4 contact is forcibly closed when passing the KM4 contact. In the actual measurement process, if the resistance value between V11 and a certain point shows infinity, it is the fault point. After the fault point is found, the service personnel can reconnect the 203 line to effectively eliminate the fault.
3 check machine parameter inspection method
At present, most of them use automatic machine tools. During actual use, the operator automatically adjusts the operating parameters of their motion state. When the operator operates or sets these parameters, if the improper situation occurs, the machine's electrical circuit may be faulty. . When the maintenance personnel repairs the electrical circuit of the machine tool, if the fault cannot be detected by routine, the maintenance personnel can check the parameters related to the machine tool work one by one, and judge and analyze the machine fault to determine whether the parameter is improperly controlled. If so, the relevant parameters should be reset or changed, and the damage in the electrical circuit should be repaired.
In the current production process, machine tool equipment is widely used and plays an important role in enterprise production. In the current application process of machine tools, there are inevitably some faults in the electrical circuit of the machine tool. In order to make the machine tool equipment run better, the faults should be effectively processed. In the application process of machine tools, the electrical line status should be reasonably analyzed. The maintenance personnel should choose to use effective methods to check and handle the faults in the electrical circuit on the basis of mastering the electrical circuit faults, so that the machine tool equipment can operate normally. .
