DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application solves the problem that traditional round tube straightness measuring instruments such as roundness measuring instruments and three-dimensional coordinate measuring machines are expensive and inconvenient to load and unload round tube parts. These devices are usually large in size and difficult to transport or move. Therefore, it is not easy to perform online testing at the customer's inspection and maintenance site, which limits their application flexibility and leads to increased testing costs.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses a round tube straightness measuring instrument, according to the attached Figure 1-4 As shown, it includes a measuring device base 1, a supporting base 2 is fixedly connected to the measuring device base 1, a motor body 3 is fixedly connected to the supporting base 2, and a round tube clamping assembly is provided at the output end of the motor body 3;

[0026] The round tube clamping assembly includes a control seat 4 fixedly connected to the output end of the motor body 3, a T-shaped slider 401 is slidably connected inside the control seat 4, and a slide groove 402 corresponding to the position of the T-shaped slider 401 is opened on the control seat 4;

[0027] A double-threaded screw rod 403 is rotatably connected to the control seat 4, a rotating handle 404 is provided on the double-threaded screw rod 403, the double-threaded screw rod 403 is threadedly connected to the T-shaped slider 401, and a round tube clamp 5 is provided on the T-shaped slider 401;

[0028] The round tube clamping assembly provided in the device is used to clamp the round tube, so as to facilitate detection. When clamping the round tube, the round tube is first placed between the two groups of round tube clamps 5, and then the rotating handle 404 is rotated to drive the double-threaded screw 403 to rotate, and the double-threaded screw 403 drives the two groups of T-shaped sliders 401 to move toward each other, and the T-shaped slider 401 drives the round tube clamp 5 to move, and finally the two groups of round tube clamps 5 are used to clamp and limit the round tube.

[0029] A guide rod 6 is fixedly connected to the side of the support fixing seat 2, a slide 7 is slidably connected to the guide rod 6, a rangefinder 8 is installed on the slide 7, the rangefinder 8 is an ultrasonic rangefinder, a mounting plate 801 is provided on the rangefinder 8, the mounting plate 801 is fixed to the slide 7, and the mounting plate 801 and the slide 7 are fixed by bolts, which are convenient for disassembly and assembly, and easy for replacement, upgrading or maintenance;

[0030] The device uses a distance meter 8 to measure the straightness of the round tube. The measuring principle is that after the round tube is limited, the motor body 3 drives the control seat 4 to rotate, and the control seat 4 drives the round tube clamp 5 and the round tube to rotate. When the round tube rotates, the distance meter 8 is used to measure the real-time spacing of the round tube during rotation. At the same time, the distance meter 8 is moved horizontally so that the distance meter 8 drives the slide 7 to slide horizontally along the guide rod 6, and the data of the spacing measured by the distance meter 8 is observed. If the data is constant, the straightness of the round tube is good. If the data is not constant, the straightness of the round tube is not good. The larger the data deviation, the worse the straightness of the round tube.

[0031] A limit plate 601 is fixedly connected to the base 1 of the measuring device, and the limit plate 601 is fixed to the guide rod 6. Through the design of the limit plate 601, the guide rod 6 is reinforced, and the supporting effect on the slide 7 is good, ensuring that the slide 7 has a good bearing effect on the rangefinder 8. The rangefinder 8 adopts an ultrasonic rangefinder, which has low cost and is easy to maintain.

[0032] A handle 701 and a protective rod 702 are provided on the slide 7. The handle 701 is provided to facilitate the lateral sliding of the slide 7, and the protective rod 702 is provided to provide protection for the rangefinder 8.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
