[0019] Embodiment 1:
[0020] like Figure 1-3As shown, a tool for measuring the outer diameter of a pipe comprises a U-shaped frame 1, which is placed with its opening facing upwards, and I-shaped frames 2 are installed on the inner walls on both sides of the open end of the U-shaped frame 1, and limiting elements are installed on the four ends of each I-shaped frame 2. Each I-shaped frame 2 is also provided with a placement mechanism for placing a measuring tool, and an elastic mechanism for applying a pre-tightening force to the pipe 10 through the limiting element is provided between the I-shaped frame 2 and the U-shaped frame 1 on the right side, and the I-shaped frame 2 and the U-shaped frame 1 on the left side are connected by screws.
[0021] Preferably, the limiting element is a bearing 3 , and the bearing 3 is rotatably connected to the I-frame 2 .
[0022] Preferably, the placement mechanism includes a V-block 4, which is arranged in the middle of the connecting rod of the I-frame 2. The center dividing surfaces of all V-blocks 4 are on the same plane. The micrometer 8 probe is placed on the V-block 4 for measurement, which saves the step of finding the right position and is more convenient.
[0023] Preferably, there are two V-shaped blocks 4 in each storage mechanism, which are symmetrically arranged on the connecting rod of the I-shaped frame 2, so that the device can be used in either upright or inverted position.
[0024] Preferably, the elastic mechanism includes a spring 5 and a guide column 6 arranged in the spring 5, the guide column 6 is slidably connected to the U-shaped frame 1, the guide column 6 is fixedly connected to the I-shaped frame 2, and a limiting convex ring is provided at one end of the guide column 6 away from the I-shaped frame 2. The limiting convex ring is used to limit the extreme position of the guide column 6 when the length of the spring 5 is the longest, thereby preventing the guide column 6 from falling off the U-shaped frame 1.
[0025] like Figure 4 As shown, when in use, the measured pipe 10 is clamped by the bearing 3, and the pre-tightening force is applied by the spring 5 to fix the pipe 10. The center plane of the two sets of V-blocks 4 is coplanar with the axis of the pipe 10. The micrometer 8 probe is placed on the V-block 4, and the ratchet is rotated to make the micrometer probe 9 contact with the product, and the displayed value is read. By rotating the pipe 10 or the U-frame, multiple diameter values distributed in the same plane can be measured, and the roundness of the pipe 10 can be measured.
[0026] The tube 10 is quickly limited by the elastic mechanism in cooperation with the limiting element, and the diameter can be quickly measured after the measuring tool is placed, eliminating the step of adjusting the axis, avoiding measurement errors caused by human factors, and improving detection efficiency.
[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
