A rotating mechanism, the rotating mechanism is arranged on the upper surface of the fixing frame 2;

Among them, the rotating mechanism includes a No. 1 motor 5, which is fixedly mounted on the rear side of the right surface of the mounting plate 4. The other end of the output shaft of the No. 1 motor 5 is fixedly sleeved with a lead screw 6. The left end of the lead screw 6 penetrates the mounting plate 4 and extends to the left side of the mounting plate 4. The outer surface of the lead screw 6 is threadedly sleeved with a moving block 7 located between the two mounting plates 4. The front surface of the moving block 7 is fixedly connected with a tooth plate 8. The outer surface of the tooth plate 8 is meshed with the outer surface of the gear 3. The rotation of the lead screw 6 causes the moving block 7 to drive the tooth plate 8 to move so that the gear 3 rotates as a whole.

The operation of motor No. 1 will cause the lead screw 6 to start rotating. At this time, the moving block 7 and the toothed plate 8 will start to move to the left driven by the lead screw 6. Since the outer surfaces of the gear 3 and the toothed plate 8 are meshed, the gear 3 as a whole will rotate driven by the toothed plate 8, causing the cutting angle to change.

The inner surface of the front side of the moving block 7 is movably sleeved with a limit rod 9, and both left and right ends of the limit rod 9 penetrate the moving block 7 and extend to the outside of the moving block 7 and are fixedly connected to the outer surfaces of the two mounting plates 4 respectively.

The design of the limiting rod 9 limits the movement of the moving block 7, thereby ensuring the stability of the moving block 7 when it moves left and right as a whole.

A pneumatic cylinder 10 is fixedly installed in the middle of the upper surface of the gear 3 , and the bottom end of the pneumatic cylinder 10 passes through the gear 3 and extends to the inside of the fixing frame 2 and is fixedly connected to the mounting frame 11 .

When the pneumatic cylinder 10 is in operation, the mounting frame 11 as a whole starts to move up and down.

A second motor 12 is fixedly mounted on the inner surface of the bottom end of the mounting frame 11 , a round shaft 13 is fixedly sleeved on the other end of the output shaft of the second motor 12 , and a cutting wheel 14 located directly below the pneumatic cylinder 10 is fixedly sleeved on the outer surface of the round shaft 13 .

When the second motor 12 is running, the circular shaft 13 will drive the cutting wheel 14 to start rotating.

Among them, a cutting groove 15 located below the fixed frame 2 is opened on the rear side of the upper surface of the bed body 1, a sliding groove 16 is opened in the middle of the upper surface of the bed body 1, and placement blocks 17 are fixedly connected to the front and rear sides of the upper surface of the bed body 1. A No. 3 motor 18 is fixedly installed on the left side of the lower surface of the bed body 1, and a rotating shaft 19 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 18, and a rotating shaft 19 is fixedly sleeved on the outer surface of the rotating shaft 19. A rotating rod 20 located below the sliding groove 16 is fixedly sleeved.

When the third motor 18 is running, the rotating shaft 19 will drive the rotating rod 20 to start rotating.

The two ends of the rotary rod 20 are hinged with connecting rods 21 , and the other end of the connecting rod 21 is hinged with a sliding block 22 . There are two sliding blocks 22 , and the top ends of the two sliding blocks 22 pass through the sliding slot 16 and extend to the top of the bed 1 .

When the rotary rod 20 rotates and causes the two connecting rods 21 to start rotating, the other ends of the two connecting rods 21 will pull the two sliding blocks 22 respectively, so that the two sliding blocks 22 start to move toward each other along the inner surface of the sliding groove 16 .

Among them, the upper surfaces of the two sliding blocks 22 are movably connected to the fixed blocks 23, and the upper surface of the fixed blocks 23 is movably connected to the bolts 24. The bottom ends of the bolts 24 pass through the fixed blocks 23 and the sliding blocks 22 in sequence and extend to the interior of the sliding blocks 22. The outer surface of the bolts 24 and the inner surface of the sliding blocks 22 are threadedly connected.

Due to the design of the bolt 24, the operator can replace the fixing block 23 according to the different diameters of the cut pipe.

The working principle and use process of this utility model:

First, the operator selects a suitable fixing block 23 according to the diameter of the pipe to be cut and uses the bolt 24 to fix the fixing block 23 above the sliding block 22. Then the operator places the pipe on the upper surface of the two placement blocks 17 and starts the No. 3 motor 18. The operation of the No. 3 motor 18 will cause the rotating shaft 19 to drive the rotating rod 20 to start rotating, and the rotation of the rotating rod 20 will drive the two connecting rods 21, so that the two connecting rods 21 start to rotate with the two ends of the rotating rod 20 as the axis. At the same time, the other ends of the two connecting rods 21 will pull the two sliding blocks 22, so that the two sliding blocks 22 as a whole start to move toward each other under the limit of the sliding groove 16. Finally, as the two sliding blocks 22 move as a whole, the two fixing blocks 23 will move to the outer surface of the pipe and clamp the pipe.

At this time, the operator starts motor No. 1 5. The operation of motor No. 1 will cause the lead screw 6 to start rotating. At this time, the moving block 7 as a whole will start to move to the left under the drive of the lead screw 6 and the limit of the limit rod 9. In this process, due to the meshing of the tooth plate 8 and the outer surface of the gear 3, the movement of the tooth plate 8 will cause the gear 3 to start rotating as a whole. During this period, the rotation of the cutting wheel 14 will cause the cutting angle of the cutting wheel 14 to the pipe fitting to change. When the cutting angle of the cutting wheel 14 meets the cutting needs of the operator, the operator starts the pneumatic cylinder 10 and motor No. 2 12. The operation of the pneumatic cylinder 10 will cause the mounting frame 11 to start moving downward as a whole. The operation of motor No. 2 12 will cause the circular shaft 13 to drive the cutting wheel 14 to start rotating as a whole. Finally, under the joint action of the cutting wheel 14 and the mounting frame 11, the cutting wheel 14 completes the cutting of the pipe fitting.
