Detailed Description
The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrative purposes and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.
Referring to fig. 3-4, for the structural schematic diagram of the embodiment of the utility model provides a special utensil of examining of hole size detection, including handle 1, and set up respectively at 1 length direction both ends of handle first detection piece 2 and second detection piece 3, first detection piece 2 includes interconnect's first connecting portion 2-1 and first detection portion 2-2, second detection piece 3 includes interconnect's second connecting portion 3-1 and second detection portion 3-2, wherein first detection piece 2 is leading to the rule, second detection piece 3 is the no-go rule, the detection size of first detection portion 2-2 is less than second detection portion 3-2. The handle 1 is cylindrical, the first detection part 2-2 and the second detection part 3-2 are both flat plates, the thicknesses of the first detection part 2-2 and the second detection part 3-2 are smaller than the width of the strip-shaped groove 102 of the product 100, the dimension (namely the detection dimension) of the first detection part 2-2 and the second detection part 3-2 in the direction perpendicular to the axial direction of the handle 1 is used for detecting the dimension of the inner cavity 101, the axial lengths of the first detection part 2-2 and the second detection part 3-2 are set according to the axial length of the inner cavity 101 and can extend into the inner cavity 101, and whether the dimension of the inner cavity 101 is in a qualified range is detected through the first detection part 2-2 of the go gauge and the second detection part 3-2 of the no-go gauge.
The size of the first connecting part 2-1 in the direction perpendicular to the axial direction of the handle 1 is smaller than that of the first detecting part 2-2, the size of the second connecting part 3-1 in the direction perpendicular to the axial direction of the handle 1 is smaller than that of the second detecting part 3-2, the first detecting part 2-2 or the second detecting part 3-2 is placed in the strip-shaped groove 102 of the product 100, then the first detecting part 2-2 or the second detecting part 3-2 is rotated, the first detecting part 2-2 or the second detecting part 3-2 is located in the inner cavity 101 and below the steel ball locking notch 103, and the size of the inner cavity 101 is detected by rotating the first detecting part 2-2 or the second detecting part 3-2180 degrees.
In this example, the first detecting part 2 and the second detecting part 3 are symmetrically arranged along the axial direction of the handle 1, and the first connecting part 2-1 is in a flat plate shape and has the same thickness as the first detecting part 2-2; the second connecting portion 3-1 is in a flat plate shape and has the same thickness as the second detecting portion 3-2.
