[0014] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0015] exist Figure 1 A pipe edge grinding device includes a main body 1. The main body 1 includes a grinding component for grinding burrs on the pipe edge and a moving component for moving the grinding component along the pipe edge. The grinding component is mounted on the moving component. The grinding component includes a grinding shell 2, which is U-shaped for easy fastening to the pipe edge. The inner side of the grinding shell 2 has a groove for fastening to the pipe edge. A fixed grinding wheel 201 for grinding burrs is provided on the side of the groove. A first motor 202 for driving the fixed grinding wheel 201 to rotate is provided between the fixed grinding wheel 201 and the groove. One end of the first motor 202 is connected to the fixed grinding wheel 201, and the other end is connected to the side of the groove. Movable grinding wheels 203 are provided on the upper and lower surfaces of the groove. A driving mechanism is provided between the movable grinding wheel 203 and the groove. The second motor 204 rotates the movable grinding wheel 203, and the first electric telescopic rod 205 drives the movable grinding wheel 203 to rise and fall. One end of the second motor 204 is connected to the movable grinding wheel 203, and the other end is connected to the bottom end of the first electric telescopic rod 205. The top end of the first electric telescopic rod 205 is connected to the upper or lower end face of the groove. The first electric telescopic rod 205 extends according to the thickness so that the movable grinding wheel 203 contacts the pipe and can grind the pipe. The rotation of the first motor 202 and the second motor 204 drives the grinding wheel to rotate, thereby achieving the purpose of grinding burrs on the pipe. In use, the grinding shell 1 is fastened to the edge of the pipe, the first electric telescopic rod 205 extends and drives the movable grinding wheel 203 to contact the pipe, and the fixed grinding wheel 201 and the movable grinding wheel 203 rotate to grind the pipe.

[0016] In this embodiment, the movable component includes a movable housing 3 installed outside the grinding housing 2. The movable housing 3 is also U-shaped to facilitate fastening to the edge of the pipe. Multiple second electric telescopic rods 301 are provided on both sides of the inner side of the movable housing 3 to retract and contact the pipe. The top of the electric telescopic rod is connected to the movable housing 3, and a pressure sensor 302 is installed at the bottom. The second electric telescopic rods 301 extend and sense pressure through the pressure sensor 302. When a specified pressure is reached, they stop extending, thereby supporting the main body 1 of the device on the pipe and preventing it from falling. The pressure threshold can be set according to actual conditions; for example, a smoother pipe surface requires a higher pressure, while a rougher pipe surface requires a lower pressure. Furthermore, if the pipe is placed horizontally... If the main body 1 is prone to falling, a larger pressure is required. If the pipe is placed vertically, the main body 1 is less likely to fall due to gravity, and a smaller pressure is required. The inner ends of the movable outer shell 3 are equipped with electric wheels 303 that drive the movable outer shell 3 to move. The electric wheels 303 cannot turn at angles, so the pipe to be ground needs to be round. If a square pipe needs to be ground, the position of the main body 1 needs to be manually adjusted. The electric wheels 303 are common devices that can be driven by electricity to move the wheel body, such as by a rotary motor to drive the wheel body to rotate. In use, the groove is fastened to the edge of the pipe, the fixed grinding wheel 201 and the movable grinding wheel 203 are used to grind burrs, the second electric telescopic rod 301 extends to support the grinding component to prevent it from falling, and the electric wheels 303 drive the grinding component to move.

The thickness sensor 206 is a sensor that measures the thickness of the material and its surface coating, such as the Thermo Scientific Laser TX optical thickness gauge. The thickness sensor 206 senses the thickness of the pipe, thereby causing the electric telescopic rod to extend and make the movable grinding wheel 203 contact the pipe.

[0018] In this embodiment, a silicone sleeve is fitted at the bottom of the second electric telescopic rod 301 to increase friction and prevent the grinding component from falling off. However, the friction is less than the power of the electric wheel 303 to move, and does not affect the electric wheel 303 from driving the grinding component to move.

[0019] In this embodiment, the electric wheel 303 is provided with a third electric telescopic rod 304. The top end of the third electric telescopic rod 304 is connected to the movable housing 3, and the bottom end is connected to the electric wheel 303. The third electric telescopic rod 304 drives the electric wheel 303 to extend and retract according to the pipe thickness information, so that the electric wheel 303 contacts the pipe and moves on the pipe.

The storage battery 5 provides power to the main body 1 of the device, and the interface 6 is connected to an external power source to charge the storage battery 5.

[0022] In this embodiment, the microcontroller 401 is a common electrical component, such as a microcontroller of model AT89C2051 or TMS320VC5509A.

[0023] In this embodiment, the first motor 202 and the second motor 204 are common rotating motor devices, such as GB / T4831-2016 model and Y160M-4 model rotating motors.

[0024] In this embodiment, the first electric telescopic pole 205 and the second electric telescopic pole 301 are common electric pole devices, such as the HB-DJ806 model mini electric telescopic pole, etc.

[0025] In this embodiment, the pressure sensor 302 is a common pressure sensor 302, such as the LWPF2 model pressure sensor 302.

The device of this utility model can be connected to an external power source or a built-in battery through a power cord to provide power to the device. Those skilled in the art can implement it, so it will not be described in detail here.

The thickness sensor 206 senses the pipe thickness, and the first electric telescopic rod 205 extends according to the thickness, allowing the movable grinding wheel 203 to contact the pipe and grind it. Simultaneously, the second electric telescopic rod 301 extends and senses the pressure through the pressure sensor 302. When the specified pressure is reached, the extension stops, thus supporting the main body 1 on the pipe and preventing it from falling. Finally, the first motor 202 and the second motor 204 drive the fixed grinding wheel 201 and the movable grinding wheel 203 to rotate, grinding the edge of the pipe. The third electric telescopic rod 304 extends, causing the electric wheel 303 to move the grinding assembly on the pipe, thus completing the entire grinding process.
