Detailed Description
The utility model is further described below with reference to the accompanying drawings, the scope of the utility model not being limited to the following:
as shown in fig. 3-6, a gauge for precisely detecting the external dimension of a sealing ring comprises a detection tool and a press-fitting assembly, wherein the detection tool comprises a base 5, a base plate 13 is fixedly arranged on the bottom surface of the base 5, the base plate 13 is a rectangular block, the base plate 13 plays a role of supporting the base 5, a cylinder 6 matched with a through hole 4 of the sealing ring is fixedly arranged on the top surface of the base 5, a conical table 7 matched with a conical hole 3 of the sealing ring is fixedly arranged on the top surface of the cylinder 6, the conical table 7, the cylinder 6 and the base 5 are coaxially arranged, and a threaded hole 8 which sequentially penetrates through the conical table 7, the cylinder 6 and the base 5 along the axial direction is formed in the top surface of the cylinder 6; the press-fit assembly comprises a pressing plate 9, a locking screw 10 and a spring 11, wherein the pressing plate 9 is an iron plate or a stainless steel plate, the outer diameter of the pressing plate 9 is smaller than that of a sealing ring, a through groove 12 is formed in the middle of the pressing plate 9, the spring 11 is sleeved outside a threaded rod of the locking screw 10, one end of the spring 11 is fixedly arranged on the bottom surface of a screw head of the locking screw 10, and the diameter of an external thread of the locking screw 10 is equal to that of the threaded hole 8.
The working process of the utility model is as follows:
s1, a worker firstly flatly places a backing plate 13 of a detection tool on a workbench, then takes a sealing ring 14 to be detected, sleeves a conical hole 3 of the sealing ring 14 on a conical table 7, and sleeves a through hole 4 of the sealing ring 14 on a cylinder 6, so that the primary tool of the sealing ring 14 is realized, and the primary tool is shown in FIG. 7;
s2, a worker horizontally places the pressing plate 9 of the press-fit assembly on the top surface of the sealing ring 14, ensures that the through groove 12 of the pressing plate 9 is communicated with the central hole 2 of the sealing ring 14, as shown in fig. 8, sequentially penetrates through the through groove 12 of the pressing plate 9 and the central hole 2 of the sealing ring 14 through the threaded rod of the locking screw 10 of the press-fit assembly, and finally is in threaded connection with the threaded hole 8, as shown in fig. 9; then the worker gradually rotates the screw head of the locking screw 10, and after the locking screw 10 moves downwards for a certain distance, the spring 11 is compressed, namely the spring 11 is propped against between the screw head of the locking screw 10 and the pressing plate 9, at the moment, the spring 11 applies pressure to the pressing plate 9, the pressing plate 9 applies pressure to the top material of the sealing ring 14, the direction of the application of the pressure is shown by an arrow in fig. 9, under the pressure, the arched bulge at the top of the sealing ring 14 is pressed on the top surface of the cylinder 6, and therefore the top surface of the sealing ring 14 is in a flat state;
