[0002] Ring gauge is also called calibration ring gauge, which is a kind of ring with specific size and attribute for correcting the deficiency of measuring tool. Ring gauge is the limit gauge for shaft, mainly used for measuring the shaft or other external dimensions with tolerance grade of 1T6-1T16.

[0003] According to the appearance, ring gauge can be divided into smooth ring gauge, threaded ring gauge, parallel threaded ring gauge and the like. In the prior art, smooth ring gauge is single piece, one ring gauge can only correct one aperture size, and the outer diameter size of ring gauges of different specifications is inconsistent, so they cannot be combined and stacked for use. In actual application, when multiple apertures of machined parts need to be measured, multiple ring gauges need to be prepared, which occupies space and is not easy to store. Therefore, it is necessary to study a scheme to solve the above problems. SUMMARY

[0004] Therefore, the utility model provides a combined smooth ring gauge, which can effectively solve the problems of space occupation and storage difficulty of the existing ring gauge.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A combined smooth ring gauge comprises a plurality of ring bodies, the outer contour of each ring body is the same in size, each ring body is provided with a measuring inner hole, the apertures of the measuring inner holes of the plurality of ring bodies are different, and the plurality of ring bodies can be separated and combined and fixed together.

[0007] Preferably, the aperture of the measuring inner hole is 0-100mm, and the outer diameter of the plurality of ring bodies is 135mm.

[0008] Preferably, the aperture of the measuring inner hole is 101-200mm, and the outer diameter of the plurality of ring bodies is 235mm.

[0009] Preferably, the thicknesses of the plurality of ring bodies are the same.

[0010] Preferably, the thicknesses of the plurality of ring bodies are the same.

[0011] Preferably, the plurality of ring bodies are fixed together by bolts.

[0012] Preferably, two bolt holes are formed in each of the plurality of ring bodies, the two bolt holes are radially symmetrical, and two bolts are respectively arranged in the two bolt holes of each ring body for fixation.

[0013] The utility model discloses a kind of ring gauges, which has obvious advantages and beneficial effects compared with prior art, specifically speaking, as known from the above technical solution:

[0014] By adopting multiple ring gauge bodies, the outer contour of each ring gauge body is the same in shape and size, the hole diameters of the measuring inner holes of the multiple ring gauge bodies are different, and the multiple ring gauge bodies are separable and fixed together to form a whole, which occupies small working space during use and is very convenient to store and arrange when not in use, thus bringing convenience for use.
