The invention relates to a detection tool for the groove medium diameter of a disc insulator. The detection tool comprises an upper beam and a first measuring arm and a second measuring arm which are respectively arranged at the two ends of the upper beam; one end, far away from the upper beam of the first measuring arm is provided with a first positioning pin; a tuning rod and a detection positioning pin are arranged on the second measuring arm; the two ends of the tuning rod are respectively provided with a second positioning pin; a guide pipe is fixedly positioned on the second measuring arm; the center line of the guide pipe is parallel to the center lines of the first positioning pin and the detection positioning pin; the tuning rod is arranged on the guide pipe along a moving sleeve; a sliding rod is positioned inside the guide pipe in a moving and guiding manner; one end of the sliding rod is provided with a detection end surface in contact matching with a measuring head of a dial indicator; a positioning hole is formed in the circumferential direction of the sliding rod; a third positioning pin is inserted into the sliding rod through the positioning hole; the detection positioning pin is inserted into the sliding rod; a slot hole is formed in a pipe wall of the guide pipe; and one end of the guide pipe is provided with a socket used for inserting and fixing the dial indicator. By the detection tool, the problem of incapability of measuring the groove medium diameter of an annular groove on an external edge of the disc insulator is solved.
Description
technical field [0001] The invention relates to a device for machining detection, in particular to a pot-type insulator groove middle diameter inspection tool. Background technique [0002] Insulators are one of the indispensable parts of high-voltage and ultra-high-voltage electrical equipment, and their shape and precision directly affect the working performance and safety performance of high-voltage electrical equipment. Basin insulator is one of the most widely used insulators. Its shape and structure are as follows: Figure 1-3 As shown, the truncated conical insulating cover 51 including the middle part and the valgus edge 52 integrally connected to the large diameter end of the insulating cover 51 are provided with ring grooves 53 on both sides of the valgus edge 52, and the The centerline of the ring groove 53 coincides with the centerline of the insulating cover 51 . The size of the middle diameter of the ring groove 53 (the diameter of a circle equal to the distan...
