A metal pipe chamfering apparatus, as shown in fig. 1 and 2, comprises a support frame 1, and a pipe clamping assembly 2 and an adjustable grinding assembly 3 disposed opposite to each other on the support frame 1.

In operation of the pipe clamping assembly 2, the metal pipe to be processed is clamped on the multi-grip chuck 23, and the spindle 22 is preferably hollow for convenient clamping of the longer metal pipe. After the clamping is stable, the gear motor 241 rotates to drive the synchronous pulley 242 to rotate, the main shaft 22 is driven to rotate through the transmission of the synchronous belt 243, the multi-grab chuck 23 is further driven to rotate, and finally the clamped metal pipe rotates.

The moving direction of the second linear module 32 is consistent with the axial direction of the spindle 22, and the moving direction of the first linear module 31 is perpendicular to the axial direction of the spindle 22.

In the above-described adjustable grinding assembly 3, the first linear module 31 and the second linear module 32 are moved in the horizontal direction to adjust the position of the grinding wheel 37. Specifically, the movement direction of the first linear die set 31 is perpendicular to the axial direction of the spindle 22, so that it can move the grinding wheel 37 along the diameter direction of the metal pipe to accommodate the metal pipes of different diameters; the second linear die set 32 has a movement direction consistent with the axial direction of the main shaft 22, so that it is used to move the grinding wheel 37 toward and away from the end of the metal pipe, when the grinding wheel 37 moves toward and away from the metal pipe, the cutting amount of the grinding wheel 37 on the metal pipe increases, that is, the groove depth of the obtained chamfer increases, and conversely, the groove depth decreases. The upright post 34 is rotatably arranged on the bearing platform 33, and the included angle between the end face of the grinding wheel 37 and the section of the metal pipe can be adjusted by adjusting the angle of the upright post 34, namely the bevel angle of the formed chamfer angle.

When the height of the grinding wheel 37 needs to be adjusted, the hand wheel 345 is rocked to drive the threaded rod 346 to rotate, and the threaded rod 346 rotates to drive the lifting tooth 351 to move up and down, so that the height of the lifting frame 35 is adjusted. Preferably, the threaded rod 346 with a smaller lead angle is selected, so that the lead angle is smaller than the equivalent friction angle, and the threaded rod 346 and the lifting tooth 351 form self-locking fit, so that the lifting frame 35 is automatically locked and cannot slide down under the action of gravity after the hand wheel 345 is loosened.

Further, the outer periphery of the grinding wheel 37 is also provided with a semi-open shield 38 for restricting the splashing of the scrap iron around. The shield 38 is also provided with a cooling pipe 39, and the nozzle of the cooling pipe 39 is aligned with the grinding wheel 37, and cooling air can be supplied to the grinding wheel 37 through the cooling pipe 39 to reduce the grinding temperature.
