Manufacturing method of bipolar thermocouple test piece and thermocouple device and grinding and temperature-measuring device

Abstract

The invention discloses a manufacturing method of a bipolar thermocouple test piece and a thermocouple device and a grinding and temperature-measuring device. The manufacturing method of the bipolar thermocouple test piece includes the following steps: cutting a thermocouple slice made of two different materials into two sections with equal lengths according to use requirements, respectively welding two thermocouple compensation wires with different polarities with the two thermocouple slices, adhering the front side and the reverse side of the first thermocouple slice with an adhesive element, enabling the two thermocouple slices to be aligned with each other, and adhering the outer side of the second thermocouple slice with an adhesive element so that the two thermocouple slices are attached but do not contact with each other and the thermocouple compensation wires do not contact with each other. The manufacturing method of the bipolar thermocouple test piece and the thermocouple device and the grinding and temperature-measuring device can reduce breaking possibility of mica pieces on an insulating layer, improves insulating reliability of two poles of a thermocouple, is stable and reliable in thermoelectric signal, and improves convenience of manufacturing of the thermocouple.

Description

technical field [0001] The present invention relates to a bipolar thermocouple test piece, a method for making a thermocouple device, and a grinding temperature measuring device, in particular to a bipolar thermocouple test piece, a method for making a thermocouple device, and a device based on the thermocouple device. Grinding surface temperature measuring device. Background technique [0002] During the grinding process, the grinding temperature is an important factor affecting the surface quality of the workpiece. In order to reduce the surface roughness and surface residual stress of the workpiece and avoid burns of the workpiece, it is of great significance to control the grinding temperature within a certain range. At present, the methods for measuring the temperature of the grinding surface mainly include: thermocouple temperature measurement, optical fiber temperature measurement, and infrared temperature measurement. Among them, when the workpiece is a thermocoupl...
