Design of automatic measuring device for assembly dimensions of automobile water pump based on TRIZ
The automobile water pump's accuracy in assembly directly affects its cooling capacity.After the task of assem-bly is completed,the key assembly dimensions are measured automatically;it is necessary to integrate the measuring device into the automatic assembly line in a proper manner,so as to improve the accuracy and efficiency in measurement,ensure the assem-bly quality and reduce the rate of nonconforming products.In this article,the TRIZ theory is used to analyze both the problems and the technical contradictions in the design of such automatic measuring devices.Based on the invention principle of TRIZ,a modular design scheme is proposed to solve the technical contradictions.According to the concept of mechatronics design,efforts are made to design the automatic measuring device's mechanical structure,electrical control system,and data-processing software on the upper computer.The experiment of automatic measurement of assembly dimensions is conducted on the physical prototype;both the accuracy and repeatability in measurement are calculated and analyzed to verify that this design is effective.
