Abstract

The invention relates to a knife-handle-type temperature monitoring device. The device mainly comprises a temperature induction module, a wireless power supply module, a wireless communication moduleand a signal acquisition system. The device is mainly characterized in that a thermocouple in the temperature induction module is embedded into a cutter with a hole or a stirring tool, and a signal amplification and conversion unit processes and converts into a digital quantity signal; the wireless power supply module adopts an electromagnetic induction coupling mode to provide electric energy foreach electronic component in the device; and the wireless communication module adopts a radio frequency technology to send the digital quantity signal corresponding to a temperature to the signal acquisition system of an upper computer. In the invention, real-time temperature induction and acquisition, wireless power supply and signal transmission are integrated into one body, on-line temperaturetesting in production processes of mechanical processing, friction-stir welding and the like is realized, and the device possesses advantages that the structure is simple; usage is convenient; and cost is low and so on.

Description

technical field [0001] The invention relates to a device for on-line monitoring of temperature in production processes such as mechanical processing and friction stir welding, belonging to the technical field of mechanical engineering testing. Background technique [0002] In machining, friction stir welding and other manufacturing processes, cutting (welding) heat not only directly affects product quality, but also accelerates tool wear. Therefore, how to optimize the process parameters and reasonably control the temperature during processing has always been one of the research hotspots in the engineering field. Obtaining the temperature and its distribution law in real time during the processing is an important way to realize the control. In fact, the knife (tool) tool is usually driven by the tool handle installed on the main shaft to perform high-speed rotation. Therefore, the most commonly used method is to drill holes in the workpiece and pre-embed thermocouples in a...
