[0021] The following is combined withFigures 1-3 A further detailed description of the present application will be given.

[0022] An embodiment of the present application discloses a grinding device for pipe fittings processing. Referring to Figures 1-3 , a grinding device for pipe fittings processing includes a single-axis feeding component 1. The single-axis feeding component 1 includes a traveling guide rail 101 for support and guidance. A traveling carriage 104 is installed on the traveling guide rail 101, and the traveling carriage 104 can move along the X-axis direction. An inner wall grinding component 2 is installed on the traveling carriage 104. The inner wall grinding component 2 includes a bracket 201 installed on the traveling carriage 104 by bolts. A connecting shaft 202 is installed on the bracket 201 through bearings. A grinding head 204 is installed at the end of the connecting shaft 202. A pipe lifting device is installed at the end of the traveling guide rail 101. The pipe lifting device is composed of several pipe supporting components 3. The pipe supporting component 3 includes a bracket 301. Two driving rollers 302 are installed on the bracket 301 through bearings. A coupling 303 is installed between two adjacent driving rollers 302. An outer wall grinding component 4 includes sliding platforms 402 installed on both sides of the pipe lifting device, and the sliding platforms 402 can move along the X-axis direction. A steering unit 405 is hinged on the sliding platform 402. A grinding unit 404 is installed on the steering unit 405. The two grinding units 404 are designed with a staggered distribution. By placing the pipe on the driving rollers 302 and driving it to rotate by the driving rollers 302, it is convenient for the grinding unit 404 and the grinding head 204 to grind the inner and outer walls of the pipe respectively. At the same time, the two grinding units 404 with a staggered distribution can limit the pipe to prevent shaking during grinding. By adjusting the grinding angle of the grinding unit 404 through the steering unit 405, pipes with different angles can be used.

[0023] Referring to Figure 1 , a lead screw 102 is installed on the side of the traveling guide rail 101. One end of the lead screw 102 is connected to a driving motor 103. A lead screw nut 105 is installed on the lead screw 102 in a transmission manner. The lead screw nut 105 is fixedly connected to the traveling carriage 104. The driving motor 103 drives the lead screw 102 to rotate. The lead screw 102 drives the lead screw nut 105 to move along the traveling guide rail 101, thereby driving the traveling carriage 104 to move along the X-axis direction for grinding long pipe fittings.

[0024] Referring to Figure 2 , a grinding motor 203 is also installed on the traveling carriage 104. The grinding motor 203 is in transmission connection with the connecting shaft 202. A connecting rod 403 is installed between the sliding platform 402 and the traveling carriage 104. By moving the traveling carriage 104, the inner wall grinding component 2 and the sliding platform 402 are driven to move, so that the grinding unit 404 and the grinding head 204 move synchronously. A sliding platform 402 is installed on the lower side of the sliding platform 402 on the pipe supporting component 3. The sliding platform 402 is supported and guided by a slide rail 401 to ensure the smoothness of the movement. When grinding pipes of different calibers, two adjacent driving rollers 302 are connected to an external power device through a transmission unit 5.

[0025] Reference Figure 2 and Figure 3 The direction adjustment unit 405 includes a rotating plate 4051 mounted on the slide 402 through a bearing, and a hinge shaft 4052 is installed at one end of the rotating plate 4051. A plurality of rotating hydraulic cylinders 4053 are fixedly sleeved on the rotating plate 4051. The rotating plate 4051 is driven by the hinge shaft 4052 to drive the rotating hydraulic cylinder 4053 to rotate, so as to adjust the angle of the grinding unit 404 to adapt to pipes of different diameters. The grinding unit 404 includes two grinding rollers 4042 mounted on the rotating hydraulic cylinder 4053 through bearings. A grinding belt 4043 is sleeved on the two grinding rollers 4042, and the end of one of the grinding rollers 4042 is connected to the rotating motor 4041. The grinding roller 4042 is driven by the rotating motor 4041 to drive the grinding belt 4043 to rotate at high speed, and the outer wall of the pipe is polished by the grinding belt 4043.

[0026] Reference Figure 3 If the pipes of the same diameter are polished, the two adjacent driving rollers 302 are connected to the screw rod 102 through the transmission unit 5, which can reduce energy consumption.

[0027] The implementation principle of a grinding device for pipe processing in the embodiment of the present application is as follows:

[0028] The pipe to be ground is placed on the drive roller 302 of the hosting assembly 3 to ensure that the pipe is stable and can rotate freely.

[0029] The positions and angles of the inner wall grinding assembly 2 and the outer wall grinding assembly 4 are adjusted to suit the size and grinding requirements of the pipe fitting.

[0030] The drive motor 103 is started, and the driving crane 104 moves along the driving guide rail 101 through the transmission of the screw rod 102 and the screw sleeve 105, driving the inner wall grinding assembly 2 and the outer wall grinding assembly 4 to move synchronously. At the same time, the driving roller 302 of the tube assembly 3 is driven to rotate through the transmission unit 5, driving the pipe to rotate.

[0031] The grinding unit 404 of the outer wall grinding assembly 4 grinds the outer wall of the pipe at a suitable angle under the adjustment of the direction adjustment unit 405. The grinding head 204 of the inner wall grinding assembly 2 grinds the inner wall of the pipe under the movement of the crane 104.

[0032] When the pipe is polished, the crane 104 is controlled to reset, and the drive motor 103 and the transmission unit 5 are turned off to stop the rotation of the pipe and the movement of the polishing assembly.

[0033] Take out the polished pipe fittings and conduct quality inspection.
