Description

Technical Field

[0001] The invention relates to the technical field of precision numerically controlled grinding machine structures, and in particular to a self-powered intelligent grinding wheel ultrasonic grinding adaptive control device. Background Art

[0002] Grinding processing has the characteristics of harsh processing environment, variable parameters, complex grinding wheel wear mechanism and strong randomness of interference factors. In particular, grinding wheel wear during the processing of high-temperature resistant and difficult-to-process materials is a bottleneck restricting the improvement of processing efficiency. At the same time, the dynamic uncertainty of the processing process makes the grinding force, grinding heat and grinding wheel vibration show strong randomness, resulting in the uncertainty of grinding state changes, fuzziness of information and coupling of multi-dimensional information. The processing state monitoring technology can provide accurate, reliable and detailed information for complex processing processes, which is of great significance for ensuring the safety of the processing system, reducing production costs and improving production efficiency.

[0003] Traditional monitoring methods usually use external sensors to transmit, collect and process signals, such as force sensors placed on the workbench, vibration sensors placed on the spindle, and temperature sensors placed inside the workpiece. However, this method is not suitable for grinding difficult-to-process materials in aerospace, where the working conditions are complex and the environment is harsh. At the same time, the processing status monitoring method that relies on manual experience directly affects the utilization rate of the grinding wheel.

[0004] The invention patent (publication number: CN202210164934.3) discloses a multi-sensor fusion intelligent toolholder monitoring device that measures cutting force, temperature and vibration in real time.

[0005] The invention patent (publication number: CN201610941714.1) discloses a composite intelligent tool system with two-dimensional ultrasonic vibration and real-time detection of cutting force. The system realizes real-time detection of the tool working status through the ultrasonic vibration component and cutting force monitoring component arranged on the tool rod, but the device does not involve the wireless transmission of the monitoring signal.

[0006] Although there have been many research results on intelligent tools, existing tool improvement plans rarely take grinding wheels into consideration; for the high-speed rotation of the grinding wheel during the grinding process, conventional signal wired transmission methods are prone to wire entanglement and cannot achieve real-time monitoring of the rotation process; when it comes to monitoring of long-term uninterrupted processing processes, traditional battery-powered methods have shortcomings in continuous power supply and power consumption management, which limits their application.

[0007] In view of the above problems, the present invention discloses a self-powered intelligent grinding wheel ultrasonic grinding adaptive control device, which takes the grinding wheel as the carrier, embeds and integrates force, temperature and vibration sensors, realizes the power supply of each module through a non-contact power transmission device, and uses WIFI technology to continuously and real-timely monitor the grinding state and grinding wheel wear state.
