With the arrival of the world's fourth industrial revolution, and the continuous development of science and technology and social production, mechanical manufacturing technology has undergone profound changes, the structure of mechanical products is more and more reasonable, and its performance, accuracy and efficiency are increasingly improved, so the production equipment of processing mechanical products has put forward high performance, high precision and high automation requirements.

As a machine tool mainly used to process box and shell parts, the machining center is worth hundreds of thousands to millions. It is generally the key equipment in the key processes of the enterprise. Once the machine is shut down, the loss is often great. Therefore, in order to give full play to the benefits of the machine tool, we must pay attention to the maintenance and repair work. Because most of the daily electrical faults of CNC machine tools are electrical faults, electrical maintenance and repair are more important.1) CNC system control part2) Servo motor and spindle motor
Focus on noise and temperature rise. If the noise or temperature rise is too large, find out whether it is a mechanical problem such as bearing or the parameter setting of its matching amplifier, and take corresponding measures to solve it. For example, if there is abnormal sound during the movement of the servo shaft, and there is no obvious parameter change after verification, it is suspected that the mechanical noise may be caused by the lead screw, coupling and non concentricity with the servo motor. Disconnect the motor from the coupling and operate the motor separately. If the motor still has noise, adjust the speed loop gain and position loop gain appropriately, Make the motor silent. If there is no noise, judge that it is the concentricity between the lead screw and the coupling, re correct the concentricity, and then connect with the motor. The problem can be eliminated.
3) Measurement feedback elementIncluding encoder, grating ruler, etc., check whether the connection of detection elements is loose and whether they are polluted by oil or dust.4) Electrical control part
Check whether the three-phase power supply voltage is normal; Check whether the electrical components are well connected; Check whether various switches are effective with the aid of CRT display diagnosis screen; Check whether all relays and contactors work normally and whether the contacts are in good condition; Whether the thermal relay, arc suppressor and other protective elements are effective; Check whether the temperature of components inside the electrical cabinet is too high. For poor contact of contactor contact, the contactor can be disassembled, the high-temperature oxide on the contact surface can be scraped off with a small file, then the sundries can be wiped out with absorbent cotton and alcohol, reassembled, and then the contact can be conducted with a multimeter.
5) Improve utilization
If the machining center is idle for a long time, when it needs to be used, first of all, each moving link of the machine tool will affect its static and dynamic transmission performance due to grease solidification, dust and even rust, reduce the accuracy of the machine tool, and the blockage of the oil circuit system is a big trouble; From the electrical point of view, the electrical control system hardware is composed of tens of thousands of electronic components, and their performance and life are very discrete. If it is not used for a long time, when power is suddenly transmitted, the components will be damaged in high current and strong voltage. Therefore, in a period of time without machining task, it is best to run the machine tool at a low speed, and at least power on the NC system frequently, or even every day.
I have encountered this situation: a horizontal machining center, using FANUC system. After running the warm-up program, it processed and found that the qualified parts were processed in the morning, and the processed parts were unqualified by noon. After inspection by the on-site processing personnel, the positioning and fixture on the machine tool are not deformed or loose. However, when the spindle box is not processed and stationary, it will deviate downward by 0.1mm along the direction of the gravity axis. The technician judges that the temperature compensation fails or the temperature sensor has poor contact. However, the phenomenon still occurs after replacing the temperature sensor and temperature module and re entering CNC parameters and temperature compensation parameters. After expert consultation, it was finally found that it was not the sensor problem, but that there was a 2-meter-long and 1-meter-wide skylight facing the main shaft and column on the machine tool. At noon, the sun directly shines on the main shaft and column, resulting in thermal deformation. After the skylight is covered, the spindle box returns to normal. This is a typical maintenance error caused by improper maintenance. Therefore, proper daily maintenance provides convenience for overall maintenance in the future.

1. Fault phenomenonWhen changing the knife, the manipulator is stuck and cannot change the knife. The position of the manipulator for changing the knife is offset, and the knife is changed.2 fault analysis and treatment
2.1 tool change principleThe machining center is a rotary tool magazine, and the tool change mechanism is cam type. The tool change process is as follows:(1) Write m06t01 to start the tool change and tool selection cycle.
(2) The spindle will stop at the oriented spindle stop point, the coolant stops, and the z-axis moves to the tool change position (second reference point).(3) Select the tool. After NC compiles it to PLC according to the t command, start selecting the tool. The tool magazine motor rotates and rotates the target tool number to the tool change point of the tool magazine. Note that the t command is the tool sleeve position of the tool magazine at this time.(4) The tool change motor drives the cam mechanism to rotate 90 from the parking position to grasp the tool in the effective tool sleeve and the tool in the spindle. At the same time, detect the change of the proximity switch state of the cam mechanism, the PMC output sends out the tool loosening command, the tool magazine tool sleeve tool loosening and the spindle tool loosening solenoid valve are powered on, the cam continues to rotate, drive the manipulator down, push down the tool handle and prepare for exchange. As shown in Figure 1.
(5) The manipulator rotates 180 to exchange the tool, the cam continues to move upward, install the tool into the spindle, and install the tool on the original spindle into the tool sleeve at the tool change position of the tool magazine. At the same time, the detection switch sends a tool tightening command to PMC, the solenoid valve loses power, the shaft tool handle is clamped, the butterfly spring retracts, and the spindle tool is clamped.(6) Change to the manipulator, continue to rotate 90 , and stop completing a set of tool change actions.2.2 fault analysis
Change the tool to the fourth step of 2.1. The tool change manipulator is stuck, and the spindle has been loosened for blowing, but the tool cannot be pulled out. Cut off the power and manually turn the tool change motor. After completing a tool change action, manually load and unload the tool, the action is normal, and the problems of spindle tightening tool are preliminarily eliminated. When the tool change process is performed again, the manipulator gets stuck and the manipulator claw at the tool magazine falls off. After the tool change is found, the manipulator installs the tool on the spindle and the position is offset, as shown in Figure 2.
After the tool is removed, it is found that the action is normal. The reason for this situation may be the offset between the manipulator and the spindle, or the deviation of the accuracy of the manipulator axis relative to the spindle axis, and the inaccurate positioning of the spindle will also lead to the offset of the tool change position. Implement the tool change action step by step, check the accurate positioning of the spindle, and eliminate the fault caused by inaccurate positioning. According to the table, the mechanicalThe axial position and rotation center distance of hand, knife sleeve and spindle are consistent, so the fault of mechanical jamming of mechanical mobile phone is also eliminated.
Recently, this machine tool mainly processes stainless steel and other material workpieces, with large cutting volume and heavy load. It runs under re cutting for a long time. It is found that the manipulator is not loose and the telescopic action of the manipulator claw is flexible. However, it is found that the adjustment block on the manipulator is worn. It is disassembled and observed that the adjustment block is mainly used to clamp the tool handle. After re repair and processing, try again, The offset disappears at the spindle position. The main cause of this fault is the large impact of the manipulator and frequent tool change, resulting in the loosening and wear of the clamping claw, as shown in Figure 3.
