[0038] Reference Figure 1 and Figure 2 In this embodiment, a push handle 14 is installed on one end of the base 1 to facilitate the staff to push the device.

[0039] Reference Figure 1 and Figure 2 In this embodiment, the telescopic assembly 2 includes a telescopic arm 21 installed on a first support frame 5, one end of the telescopic arm 21 is installed with a first driving member 22 for driving the telescopic arm 21 to extend or shorten, and the other end of the telescopic arm 21 is installed with a mounting seat 15, and the grinding assembly 3 is installed on the mounting seat 15.

[0040] Specifically, the telescopic arm 21 is a multi-section telescopic arm. When extended, it can be used for a longer pipe 17, and when shortened, it can save space. The first driving member 22 is a servo motor, which is a prior art and will not be described in detail here.

[0041] Reference Figure 3 In this embodiment, the grinding assembly 3 includes a second driving member 31 installed on the mounting seat 15, and a bending member 32 is installed on the output end of the second driving member 31. A grinding disc 33 is installed on the bending member 32 to grind the inner wall of the pipe 17. A floating support assembly 4 is rotatably provided on both sides of the grinding disc 33 on the bending member 32.

[0042] Specifically, the second driving member 31 can be a pneumatic motor, model 6AM-V, which is the existing technology and will not be elaborated on here; the second driving member 31 can drive the bending member 32 to rotate; the bending member 32 can be a metal hose, a soft shaft or a universal joint coupling; there can be multiple floating support assemblies 4. In this embodiment, there are 4 floating support assemblies 4, which are respectively located on both sides of the grinding disc 33. The floating support assemblies 4 close to the two sides of the grinding disc 33 can drive the grinding disc 33 to turn during the grinding of the bent pipe, and provide floating support on both sides of the grinding disc 33. The floating support assemblies 4 away from the two sides of the grinding disc 33 provide guiding support on the inner wall of the pipe, adapt to the angle of the bent pipe, and perform automatic alignment. Because the inner wall of the pipe 17 being ground is rough and inconsistent in size, the floating support assembly 4 is used to adapt to the inner wall of the pipe 17 with different diameters.

[0043] Reference Figure 4 and Figure 5 In this embodiment, the floating support assembly 4 includes a frustum 41 rotatably mounted on the bending member 32, a plurality of connecting seats 42 are evenly distributed on the frustum 41, a sleeve 43 is mounted on the connecting seat 42, a movable seat 44 is slidably mounted on the sleeve 43, and a guide wheel 45 is rotatably mounted on the movable seat 44.

[0044] Specifically, the bending member 32 is connected to the truncated cone 41 via a bearing. In this embodiment, there are three connecting seats 42, and each connecting seat 42 has at least one sleeve 43. The guide wheel 45 is in vertical contact with the inner wall of the pipe 17.

[0045] Among them, reference Figure 4 and Figure 5 In this embodiment, a slide groove 46 is provided in the sleeve 43 , the movable seat 44 extends into the slide groove 46 , and a spring 47 is connected between the movable seat 44 and the inner wall of the slide groove 46 .

[0046] Specifically, the movable seat 44 can move along the direction of the slide groove 46; through the setting of the spring 47, the spring 47 can be compressed when the guide wheel 45 is squeezed against the inner wall of the pipe 17, so that the guide wheel 45 can adapt to the inner wall of the pipe 17 of different diameters, thereby improving the operating stability of the grinding disc 33 inside the pipe 17 and improving the practicality of the device.

[0047] The grinding disc 33 can also move along the pipe 17 when rotating for grinding. The mutual cooperation of the spring 47, the movable seat 44 and the guide wheel 45 improves the running stability of the grinding disc 33 inside the pipe 17.

[0048] Working principle: when in use, the pipe 17 is placed on the support seat 16, and the device is moved to a suitable position through the universal wheel 13. By turning the knob 11, the adjusting column 10 is driven to move downward with the cooperation of the nut 12, and the positioning ring cylinder 7 is lifted so that the positioning ring cylinder 7 can position the end of the pipe 17. After adjustment, the pipe 17 is locked by the locking screw 9, and then the telescopic arm 21 is extended by the first driving member 22 to extend the grinding disc 33 into the interior of the pipe 17, and the second driving member 31 is started to drive the bending member 32 to rotate, thereby driving the grinding disc 33 to rotate and start grinding. Through the slow extension of the telescopic arm 21, the grinding disc 33 is driven to move along the inner wall of the pipe 17 under the action of the guide wheel 45. When encountering a curved pipe, the guide wheel 45 guides and supports the grinding disc 33 through the cooperation of the bending member 32, and automatically aligns to adapt to the angle of the curved pipe.

[0049] The utility model is convenient for processing pipes 17 with larger lengths and diameters, can adapt to the angles of the bent pipes, and can grind the inner walls of the pipes 17 . The operation is simple and convenient, and the work efficiency is improved.
