[0017] In order to make the purpose, technical scheme and advantages of the utility model embodiment more clear, the utility model technical scheme will be described clearly and completely below in conjunction with the embodiment.

[0018] EMBODIMENT

[0019] As shown in Figure 1 , Figure 2 and Figure 3 , the side hole position degree gauge, including detection table 10, detection table 10 detachably installs several convex blocks 20, and the convex block 20 is opened with the detection hole 22 and the limiting hole 23 that are arranged in cross, the inside of the detection hole 22 is movably sheathed with the detection rod 24, and the outside of the detection rod 24 is opened with the limiting slot, the inside of the limiting hole 23 is movably sheathed with the limiting shaft 26, and the outside of the limiting shaft 26 is in abutment with the limiting slot.

[0020] It needs to be explained that the several convex blocks 20 are evenly arranged around the three side walls of the detection table 10, the edge of the detection hole 22 is located on the central axis of the limiting hole 23, the depth of the limiting slot opened on the outside of the detection rod 24 is equal to the radius of the limiting hole 23, the movement range of the detection rod 24 is limited by the limiting shaft 26, so that it will not be separated from the convex block 20, and the movement distance of the detection rod 24 is the length of the limiting slot.

[0021] Specifically, the mechanical part to be detected is placed on the detection table 10, and then the detection rod 24 is pushed to extend into the side hole, so that the centering of the side hole on the mechanical part and the bolt or shaft can be quickly detected.

[0022] As Figure 1 and Figure 2 shown, the detection table 10 is provided with a plurality of positioning holes 11 and mounting holes 12, the convex block 20 is inserted with the positioning hole 11, the inside of the mounting hole 12 is inserted with the anti-skid block 13, and the anti-skid block 13 uses but is not limited to using rubber material.

[0023] Specifically, the convex block 20 is designed by plugging and unplugging, so that it is convenient to change the specific number and position according to the actual demand, so that it is more flexible and variable, and the friction of the mechanical parts can be increased by setting the anti-skid block 13, so that the mechanical parts placed on the detection table 10 are prevented from deviating during detection.

[0024] As Figure 1 , Figure 2 and Figure 3 shown, the detection table 10 is provided with a plurality of positioning holes 11 and mounting holes 12, the convex block 20 is inserted with the positioning hole 11, the inside of the mounting hole 12 is inserted with the anti-skid block 13, and the anti-skid block 13 uses but is not limited to using rubber material.

[0025] Specifically, the assembly hole 21 is in the shape of an inverted "convex" character, and after the bolt is placed in the assembly hole 21 and connected with the nut, the convex block 20 can be firmly fixed on the detection table 10.

[0026] As Figure 3 shown, the detection rod 24 is threadedly connected with the extension rod 25 at one end close to the center point of the detection table 10, and the other end is provided with a scale line.

[0027] Specifically, the extension rod 25 is threadedly connected with the detection rod 24, so that it is convenient to disassemble, when the diameter of the side hole to be measured is smaller than the diameter of the detection rod 24, the extension rod 25 of the appropriate specification can be replaced, and the length of the side hole can be clearly and definitely observed by setting the scale line.

[0028] Working principle: the mechanical parts to be detected are placed on the detection table 10, when the diameter of the side hole to be measured is greater than or equal to the diameter of the detection rod 24, the detection rod 24 can be directly pushed to extend into the side hole, when the diameter of the side hole to be measured is smaller than the diameter of the detection rod 24, the detection rod 24 is threadedly connected with the extension rod 25, so that it is convenient to disassemble, the extension rod 25 of the appropriate specification can be replaced, so that the centering of the side hole and the bolt or shaft on the mechanical parts can be quickly detected.
