In the field of shield machine manufacturing, the roundness of a shield body, especially the roundness of an anterior shield, has always been the key point of attention of shield machine manufacturing enterprises and using units. Because the size directly influences the positioning size of the edge cutter of the cutter head and whether the shield body can smoothly pass through the cutter head under the maximum excavation size. The shield body belongs to a thin-wall part, the roundness of the assembled shield body and the cutter head changes compared with the machining link of the shield body under the influence of gravity and subsequent assembly errors, and the measurement significance of the roundness of the assembled shield body and the assembled cutter head is great.
In the shield machine manufacturing industry at the present stage, after the shield body and the cutter head are integrally assembled, the method for measuring the roundness of the shield body always adopts a manual mode: firstly fixing a measuring support on a certain point of the excircle of a cutter head, then measuring the distance between the support and a shield body by using a inching distance meter or a box ruler, rotating the cutter head after one point is measured, then measuring the next point until all the 12 or more evenly divided point positions of the shield body are measured, and finally manually inputting the measured values of the point positions into a computer for data analysis to find out the highest point, the lowest point and the roundness value of the shield body. The method has the following disadvantages: the operation is complex, the operation is unsafe, and the analysis effect is poor.
