Description

Technical Field

[0001] The invention relates to the field of fault detection, and in particular to a remote electric spindle fault detection system. Background Art

[0002] The electric spindle is an important component evolved from the mechanical spindle. It can provide high-speed rotation power and keep the tool or workpiece stable during the processing, thus achieving significant improvements in performance such as rotation accuracy, rigidity and vibration. Its complex structure includes multiple key components such as housing, bearings, motor, spindle, cooling system, tool change system, tapered hole end cover, etc. The housing is not only used to install and position the electric spindle, but also provides structural support to withstand vibration and loads in various processing processes; the bearing plays an important role in supporting and reducing friction, enabling the electric spindle to operate under high speed and high load conditions, while extending the service life of the equipment.

[0003] However, long-term equipment operation or other factors may cause various faults in the electric spindle, such as bearing wear, rotational imbalance, housing problems, and stator and rotor failures. These faults will cause the performance of the machine tool to decline, the processing quality to decrease, and even in severe cases, the equipment may be damaged. Traditional fault diagnosis technology for electric spindles relies on human subjective judgment to extract features, so whether a fault occurs to a certain extent depends on expert experience. Because there are many uncontrollable factors in the actual working conditions of the electric spindle, it is difficult to predict the potential faults of the electric spindle and quickly locate the fault location based solely on people's "experience". Summary of the invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a remote electric spindle fault detection system, which can remotely and conveniently detect whether the electric spindle has a fault and locate the fault location.

[0005] The present invention proposes a remote electric spindle fault detection system, which includes an information collection module, an information transmission module and an information processing center. The information collection module is used to collect the temperature of the housing and internal bearings and the rotation speed and acceleration information of the bearings, rotor stator and rotor stator when the electric spindle is in operation, including the data generated by the electric spindle in normal operation and the signal in a fault state; the information processing center is composed of a data processing module, a remote alarm module and a display module, and the data processing module is connected to the remote alarm module and the display module respectively; the information processing center receives the signal transmitted by the information transmission module, and if there is a sign of electric spindle failure, the data processing module will quickly make a judgment and present the fault location information on the display module; at the same time, the remote alarm module will send an alarm so that necessary repair and maintenance measures can be taken in time, thereby reducing the risk of production interruption.

[0006] Furthermore, the data processing module includes a storage unit and a preprocessing unit; the storage unit receives a variety of key information from the signal acquisition module, including temperature, acceleration, rotational speed and position information provided by the position sensor; at the same time, the preprocessing unit processes the signals imported from sensors and other devices to detect potential signs of faults; when a possible fault signal is found, the preprocessing unit combines the temperature, acceleration, rotational speed data and position information to relatively accurately detect the location of the electric spindle fault.

[0007] Furthermore, the display module is used to display the rotation speed, temperature and acceleration signals of the electric spindle obtained by the signal acquisition module, and also displays the position information from the position sensor; at the same time, the data processing module is responsible for processing different status signals; if the electric spindle fails, the data processing module will identify the signal and send an indication to the display module, and the display module will display information about the fault location of the electric spindle.

[0008] Furthermore, the power supply element includes a solar panel and a battery. The solar panel captures solar energy and converts it into electrical energy to provide the required power for the display module; the battery is used to store excess electrical energy generated by the solar panel. This additional electrical energy can serve as a backup energy source when the solar panel cannot work normally. By storing excess electrical energy in the battery, the system can maintain stable operation in the absence of sunlight.

[0009] Furthermore, the information transmission module consists of two parts: an information conversion unit and an information transmitting unit. The information conversion unit is connected to the information collection module, and the signal transmitting unit is connected to the information processing center. By setting the information conversion unit and the information transmitting unit, the information is converted into an appropriate format and sent to the signal transmitting unit. The signal transmitting unit is responsible for sending this information to the information processing center.

[0010] Furthermore, the data acquisition module includes a temperature acquisition device, a speed acquisition device and an acceleration acquisition device, which respectively collect the temperature data of the bearings and the shell in the electric spindle, and collect the speed and acceleration of the bearings, stator and rotor in the electric spindle, so as to effectively monitor and record the data of various elements inside the electric spindle and provide comprehensive information on the operating status of the equipment.

[0011] Furthermore, the remote alarm module is used to issue an alarm when the data processing module detects that the electric spindle has a fault; by setting up the remote alarm module, when the data processing module detects signs of fault in the electric spindle, the remote alarm module responds and issues an obvious alarm signal to remind maintenance personnel to repair the electric spindle as soon as possible.

[0012] The present invention provides a remote electric spindle fault detection system with the advantages that: the remote electric spindle fault detection system provided in the present invention introduces an information collection module to obtain various key data inside the electric spindle in real time, including temperature, vibration, rotation speed and other information, so that the operator can have a more comprehensive understanding of the equipment performance; the information transmission module transmits the data from the acquisition module to the data processing module. This remote transmission mechanism enables the operator to monitor the operating status of the electric spindle in real time without having to visit the site in person, thereby reducing the difficulty of maintenance and monitoring; the information processing center can not only process the transmitted data, but also diagnose whether the electric spindle has a fault, discover potential problems in advance, and make maintenance work more targeted, which helps to reduce maintenance costs, reduce unnecessary downtime, and improve the reliability of equipment.
