According to an aspect of the present utility model, the diameter of described column part is less than the minimum limit of size of internal radius, and the minimum diameter of tapered segment equals the minimum limit of size of internal radius.
According to an aspect of the present utility model, the surface of described tapered segment is provided with scale, and described scale is arranged on the surface of tapered segment equably.
According to an aspect of the present utility model, described measure portion and fixed part hold together.
According to an aspect of the present utility model, the length of described column part is 2-5 ㎝.
The advantage that the utility model is implemented: because measure portion of the present utility model is comprised of column part and tapered segment, the diameter of column part is less than the minimum limit of size of internal radius, the minimum diameter of tapered segment equals the minimum limit of size of internal radius, maximum gauge is greater than the maximum limit of size of internal radius, and the surface of tapered segment is provided with the uniform scale of spacing, the diameter of scale position measuring stick and deviation are labeled in the side of scale mark, during detection, annulus is locked in measuring stick, with the internal diameter of slim annulus, whether fall into correspondingly and judge whether slim internal radius size meets accuracy requirement in deviation area, so the accuracy of detection of measuring stick is high, cost is low, very easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of a kind of measuring stick detecting for slim internal radius described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of measuring stick detecting for slim internal radius, comprise measure portion and fixed part 2, measure portion is connected with fixed part 2, described measure portion is comprised of column part 1 and tapered segment 3, the diameter of column part 1 is not more than the minimum limit of size of annulus 5 internal diameters, and the maximum gauge of tapered segment 3 is greater than the maximum limit of size of annulus 5 internal diameters.
In actual use, in order to facilitate user to read quickly and accurately the deviation of slim annulus 5 internal diameter sizes, according to slim annulus 5 actual inner diameter size and deviation ranges, the surface of tapered segment 3 is provided with scale 4, the starting point of scale 4 is the position of the minimum limit of size of slim annulus 5, scale 4 is arranged on the surface of tapered segment 3 equably, first the position of the maximum limit of size of slim annulus 5 internal diameters and the minimum limit of size is done to sign on the surface of tapered segment 3, utilize point principles such as straight line, deviation range is divided into some districts according to a certain percentage, and in middle position, also do sign, during detection, as long as slim annulus 5 is locked in measuring stick, with slim annulus 5, whether fall into correspondingly and judge whether slim annulus 5 internal diameter sizes meet accuracy requirement in deviation area.The for example internal diameter size of slim annulus 5 is Φ 8 ㎜, permissible variation scope is 0.001-0.005 ㎜, the technician of company is labeled in the maximum limit of size of slim annulus 5 8.005 ㎜ and the minimum limit of size 8.001 ㎜ the surface of tapered segment 3 and sets scale 4, utilize point principles such as straight line, deviation range is divided into Wu Ge district, be respectively 8.001-8.002 ㎜, 8.002-8.003 ㎜, 8.003-8.004 ㎜, 8.004-8.005 ㎜ and more than 8.005 ㎜, and put on respectively 8.002 ㎜ at middle scale 4, 8.003 ㎜, 8.004 ㎜, during detection, as long as slim annulus 5 is locked in measuring stick, with slim annulus 5, fall into the precision of judging slim annulus 5 internal diameter sizes in deviation area correspondingly, do not need to drop into expensive high-acruracy survey equipment or instrument, cost is low, simultaneously, in testing process, can not cause because of detection that slim annulus 5 is out of shape, detect very convenient, speed is fast, accuracy of detection is high.
The diameter of the preferred column part 1 of the utility model is less than the minimum limit of size of annulus 5 internal diameters, the minimum diameter of tapered segment 3 equals the minimum limit of size of annulus 5 internal diameters, the length of column part 1 is generally 2-5 ㎝, the concrete length of tapered segment 3 is determined according to the size of annulus 5 internal diameter sizes and deviation range, large or the deviation range of annulus 5 internal diameter sizes large, the length of tapered segment 3 is long, otherwise, annulus 5 internal diameter sizes are little and deviation range is little, and the length of tapered segment 3 is short.
In addition, the material of measure portion and fixed part 2 is all metal material, measure portion and fixed part 2 hold together, consider the technique of measuring stick processing or the situation of process equipment, measure portion can be separated and make with fixed part 2, by welding or bolt, measure portion and fixed part 2 is linked together.
