Abstract

The invention provides a crankshaft connecting rod neck follow grinding temperature measuring device. The crankshaft connecting rod neck follow grinding temperature measuring device comprises a first main shaft assembly and a second main shaft assembly, wherein the first main shaft assembly and the second main shaft assembly are opposite to each other; a connecting rod neck assembly, wherein the connecting rod neck assembly is arranged between the first main shaft assembly and the second main shaft assembly and is connected with the first main shaft assembly and the second main shaft assembly through bolts; a thermocouple wire, wherein one end of the thermocouple wire is arranged in the connecting rod neck assembly; and a conductive slip ring, wherein the conductive slip ring is arranged on the second main shaft assembly, and the other end of the thermocouple wire is connected with the conductive slip ring. Compared with the prior art, the crankshaft connecting rod neck follow grinding temperature measuring device has the following advantages that in the assembling process, the thermocouple wire can be conveniently assembled and disassembled, the thermocouple wire is arranged in a 360-degree space rang of the connecting rod neck assembly, the temperature of each grinding point in the grinding process can be conveniently detected, the temperature detection and signal outputting of each grinding point in the crankshaft follow grinding process are realized, and the connecting rod neck and the thermocouple wire can be conveniently changed.

Description

technical field [0001] The invention relates to the field of engineering testing, in particular to a dynamic measuring device for the grinding temperature during the follow-up grinding process of the connecting rod neck of the crankshaft. Background technique [0002] In the field of engineering testing, commonly used grinding temperature measurement methods include thermocouple method, infrared temperature measurement method, metallographic detection method and surface comparison method. The infrared temperature measurement method uses an infrared thermal imager to measure the entire grinding temperature field effectively and quickly in real time, with simple operation and high accuracy. However, for the follow-up grinding of the crankshaft pin, the position of the grinding point or the grinding contact area is constantly changing due to the planetary motion of the pin pin grinding point, making it difficult for the infrared thermal imager to detect the grinding point. Pre...
