Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-3 The utility model is a cutting device for welding pipe processing, comprising a welding pipe body 1, a cutting assembly 2 is arranged outside the welding pipe body 1, the cutting assembly 2 comprises a bottom plate 210, the bottom plate 210 is fixedly connected to the mounting platform, a fixing plate 207 is fixed on the upper wall of the bottom plate 210, a driving motor 202 is arranged on the front side of the fixing plate 207, a cutting blade 2021 is fixed on the power output shaft of the driving motor 202, the driving motor 202 drives the cutting blade 2021 to rotate when working, so as to realize cutting of the welding pipe body 1, Motors 203 are provided on both the left and right sides of the driving motor 202, a driving wheel 205 is fixed on the power output shaft of the motor 203, and driven wheels 208 are provided on the front and rear sides below the driving wheel 205. The motor 203 drives the driving wheel 205 to rotate, and the weld pipe body 1 is rotated under the action of the driven wheel 208, so that the rotating cutting blade 2021 cuts the wall thickness of the weld pipe body 1 and then the weld pipe body 1 is rotated to cut off the weld pipe body 1. Therefore, the use is less limited by the specifications of the weld pipe body 1.

[0030] Specifically, the fixed plate 207 is L-shaped, and a mounting block 2011 is fixed to the left wall of the driving motor 202. An electric push rod 201 is fixed to the upper wall of the mounting block 2011, and the upper end of the electric push rod 201 is fixedly connected to the fixed plate 207. The mounting block 2011 is driven to move by the operation of the electric push rod 201, thereby driving the driving motor 202 to move. When cutting, the driving motor 202 is operated, and the electric push rod 201 can drive the rotating cutting blade 2021 to move toward the welding pipe body 1 to perform the wall thickness cutting operation of the welding pipe body 1.

[0031] A mounting plate 2041 is fixed to the side wall of the motor 203 close to the driving wheel 205, an electric telescopic rod 204 is fixed to the upper wall of the mounting plate 2041, and the upper end of the electric telescopic rod 204 is fixedly connected to the fixed plate 207. The mounting plate 2041 is driven to move by the operation of the electric telescopic rod 204, thereby driving the motor 203 to move and causing the driving wheel 205 to move until the anti-slip ring 2051 contacts the outer peripheral wall of the welding pipe body 1 to fix the position of the welding pipe body 1.

[0032] An anti-slip ring 2051 is fixed to the outside of the driving wheel 205, and an anti-slip sleeve 2081 is fixed to the outside of the driven wheel 208, and the anti-slip ring 2051 and the anti-slip sleeve 2081 are both in contact with the welding pipe body 1.

By adjusting the spacing between the moving blocks 209 on the same side, the need for welding pipe bodies 1 of different diameters to be firmly fixed can be met. That is, when a larger welding pipe body 1 is cut off, the distance between the two driven wheels 208 on the same side is increased, so that the larger welding pipe body 1 is more firmly fixed.

[0035] The operation process of this embodiment is as follows: according to the diameter of the welded pipe body 1 to be cut, the adjusting motor 206 is operated to drive the screw 2061 to rotate, so that the moving block 209 moves, thereby driving the driven wheel 208 to move, and then the welded pipe body 1 is mounted on the inner side of the driven wheel 208, at which time the outer peripheral wall of the welded pipe body 1 contacts the outer peripheral wall of the anti-slip sleeve 2081, and then the electric telescopic rod 204 is extended to drive the mounting plate 2041 and the motor 203 to move downward, and drive the anti-slip ring 2051 on the driving wheel 205 to move downward until it contacts the outer peripheral wall of the welded pipe body 1 and contacts the outer peripheral wall of the anti-slip sleeve 2081. Maintaining a suitable extrusion pressure, the driving motor 202 is operated to drive the cutting disc 2021 to rotate at a high speed, and then the electric push rod 201 is extended to drive the mounting block 2011 and the driving motor 202 to descend, driving the cutting disc 2021 in a rotating state to descend until the cutting disc 2021 cuts the wall thickness of the welding pipe body 1, and then the motor 203 is operated to drive the driving wheel 205 to rotate, so that the anti-slip ring 2051 rotates, and with the cooperation of the driven wheel 208, the welding pipe body 1 in a rotating state is cut by the cutting disc 2021 in a rotating state, completing the truncation process of the welding pipe body 1.
