[0059] When the oil cylinder 3 is extended, the fixed bracket 201 and the rotating bracket 202 are close to each other, and the clamping plates 204 arranged opposite to each other can clamp the pipe B;

[0060] A vertical beveling machine provided in this embodiment drives the rotating bracket 202 to rotate through the oil cylinder 3, so that the fixed bracket 201 and the rotating bracket 202 are moved closer to / away from each other, so that the relatively arranged clamping plates 204 can clamp / release the pipe B. Through the rotation of the rotating bracket 202, the pipe B no longer needs to be put in and taken out straight up and down, but can be put in and taken out from the side, so that the displacement of the main shaft of the power head 5 in the vertical direction is greatly reduced, and at the same time the speed of putting in and taking out the pipe B is faster, which effectively improves the efficiency of batch processing of the pipe B.

[0061] In a specific embodiment, Figure 1 As shown, it also includes a fixture position adjustment mechanism 4, and the fixture position adjustment mechanism 4 includes a base 402, such as Figure 2 As shown, the base 402 is welded and fixed on the base 1;

[0079] The locking bolt 1405 is fixed together with the locking plate 1404 by threads. When the position of the blade 1402 needs to be adjusted, the locking bolt 1405 is loosened to allow the blade 1402 to slide along the guide groove 1406. When the position is determined, the locking bolt 1405 is tightened to complete the locking.

[0080] In a specific embodiment, Figure 6 As shown in the right part, the cutting edge of the blade 1403 on one of the cutter bodies 1402 is oriented at an angle to the axial direction of the spindle (cutting edge inclination), which is used to process the groove of the pipe B, and the cutting edge of the blade 1403 on the other cutter bodies 1402 is oriented at an angle to the axial direction of the spindle.
