What are the requirements for power supply of CNC manipulators?

1.the requirements for the working environment of CNC lathe manipulator equipment is thorough. CNC lathe manipulator equipment usually has requirements for a constant temperature environment. Only under constant temperature conditions can the accuracy of the manipulator and the accuracy of the working position be ensured. Usually ordinary manipulators do not have detailed requirements for room temperature, but a lot of practical promises show that when the room temperature is too high, the obstacle rate of the CNC system greatly increases.

2. CNC lathe manipulator equipment requirements for shrinking air supply system CNC machine tools usually use a lot of pneumatic components, so a clean and dry shrinking air supply system network should be connected to the workshop. Its flow and pressure should meet the requirements. The shrink air secret is installed far away from the CNC robot. According to the deployment situation in the factory building and the size of the measurement, it should be studied to install refrigerated air compressors, air filters, air storage tanks, safety valves and other equipment for the shrinking air supply system network.
3. The grid voltage vibration should be controlled between +10%~-15%. However, my country’s power supply vibration is relatively large, the quality is poor, and there are also harassment such as high-frequency pulses, plus artificial factors (such as sudden switch Power failure, etc.). Electricity peak hours, such as the one-hour control before going to work during the day or the end of get off work, and the evening, often exceed tolerances, even reaching ±20%. Make the manipulator alarm and fail to work normally, and damage the manipulator power system. It even causes the loss of related parameter data.

This phenomenon has occurred in CNC machining centers or turning centers and other machine tools, and it occurs frequently, so it should be valued. It is proposed to configure an AC voltage stabilized power supply system with automatic compensation and adjustment performance in workshops where CNC manipulators are more integrated; a single CNC manipulator can be independently configured with an AC voltage stabilizer to handle it.

4. It is proposed to connect mechanical and electrical equipment to a single power source. If it is necessary to use the remaining power supply to power certain parts of the electrical equipment (such as electronic circuits, electromagnetic clutches), these power sources should be taken as much as possible from the parts of the mechanical electrical equipment (such as transformers, transducers, etc.). For large and complex machinery including many machinery that work together in a coordinated manner and occupy a large space, more than one inductive power source may be required, which depends on the configuration of the power source of the site.

Unless the mechanical and electrical equipment is directly connected to the power source by the plug/socket, it is recommended that the power cord be directly connected to the power terminal of the power cut switch. If this is not possible, a separate terminal block should be configured for the power cord. The handle of the power cut-off switch should be easily approached, and should be installed between 0.6m and 1.9m above the easy-to-operate position. The proposed cap value is 1.7m. In this way, it may be possible to quickly cut off power in an emergency situation, reducing losses and staff casualties.
