[0002] In the manufacturing, installation, maintenance, and repair of boilers, beveling of pipe ends is a crucial process. The quality of the beveling directly affects the quality and efficiency of boiler pipe welding, which in turn relates to the overall operational safety and lifespan of the boiler.

[0003] Currently, among existing pipe beveling equipment, such as the patent with authorization announcement number CN215316012U, this utility model discloses a pipe beveling cutting table, including a worktable, a support wheel at the upper end of the worktable, a drive wheel on one side of the support wheel, a pipe pressing mechanism above the middle of the support wheel and the drive wheel, a collection box at one end of the worktable, and a positioning mechanism at the other end of the worktable. This utility model can realize the rotation of the pipe.

[0004] However, during the use of the equipment, it was found that when the pipe rolls and rotates on the support wheel, the pipe is prone to vibration and shaking, which reduces the quality of the pipe beveling and reduces the effectiveness of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a boiler maintenance pipe beveling machine that reduces the shaking and vibration during the rolling of the maintenance pipe, improves the beveling quality, and enhances the convenience of processing beveling at different angles.

[0006] This utility model discloses a boiler maintenance pipe beveling machine, comprising a housing and a grinding wheel, the grinding wheel being rotatably mounted on the inner wall of the housing; it also includes a support device, a positioning device, a first motor, a support member, and a second motor. The first motor is mounted on the outer wall of the housing, and its output end is connected to the grinding wheel. The top of the housing is rotatably connected to the outer wall of the support member. The second motor is mounted on the outer wall of the support member, and its output end is connected to the rotating end of the housing. The support member is mounted on the support device, which is used to drive the support member to move and adjust. A positioning device is provided at the bottom of the housing for positioning the pipe and vertically beveling the maintenance pipe. The tube is placed on the positioning device and fixed so that the part of the inspection tube that needs beveling faces upward. Then, the support device moves the support component to a position, so that the support component drives the grinding wheel to contact the inspection tube opening. The first motor drives the grinding wheel to rotate, so that the grinding wheel beveles the inspection tube opening. At the same time, the positioning device drives the inspection tube to rotate, so that the grinding wheel beveles different positions of the inspection tube opening. The rotation of the inspection tube driven by the positioning device reduces the shaking and vibration of the inspection tube when it rolls, improving the beveling quality. The second motor drives the housing to swing and rotate, so that the angle of the grinding wheel can be adjusted, improving the convenience of processing different angle beveling.

[0012] Preferably, the outer walls of the multiple sets of clamping members are provided with anti-slip pads to improve the clamping firmness of the multiple sets of clamping members on the inspection pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The inspection tube is placed vertically on the positioning device and fixed so that the part of the inspection tube that needs to be bevel is facing upward. Then, the support device drives the support component to move, so that the support component drives the grinding wheel to contact the inspection tube opening. The first motor drives the grinding wheel to rotate, so that the grinding wheel bevels the inspection tube opening. At the same time, the positioning device drives the inspection tube to rotate, so that the grinding wheel bevels different positions of the inspection tube opening. The rotation of the inspection tube driven by the positioning device reduces the shaking and vibration of the inspection tube when it rolls, and improves the beveling quality. The second motor drives the housing to swing and rotate, so that the angle of the grinding wheel can be adjusted, improving the convenience of processing beveling at different angles.
