DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] In this embodiment, the front, rear, left, right, top and bottom are represented by Figure 1 Describes the datum surface. Figure 1-Figure 5 , the utility model provides a technical solution:

[0021] A cutting device for ship processing steel pipes, comprising a workbench 1 with an installation cavity, a loading rack 2 is rotatably installed in the installation cavity of the workbench 1, the loading cavity width of the loading rack 2 is the same as the outer diameter of the steel pipe to be cut, the left end and the bottom end of the loading rack 2 are both in a closed state, and the right end and the upper end of the loading rack 2 are in an open state, a clamping mechanism 3 is fixedly installed on the rear surface of the loading rack 2, when the loading cavity of the loading rack 2 is filled with multiple steel pipes, the clamping mechanism 3 can press the uppermost steel pipe to make the multiple steel pipes fit together, thereby fixing the multiple steel pipes, a lifting and oblique cutting mechanism 4 and a positioning mechanism 5 are fixedly installed on the upper surface of the workbench 1, the lifting and oblique cutting mechanism 4 is located on the right side of the loading rack 2, and the positioning mechanism 5 is located on the right side of the lifting and oblique cutting mechanism 4;

[0022] When the loading rack 2 loaded with steel pipes rotates to a vertical state with the table top of the workbench 1, multiple steel pipes enter the cutting work area of ​​the lifting and oblique cutting mechanism 4. At this time, the constraint of the clamping mechanism 3 on the steel pipe is released, and the positioning mechanism 5 is activated to regularly position and align the multiple steel pipes in the loading cavity, ensuring that the position and angle of each steel pipe in the cutting coordinate system are accurately fixed, effectively reducing the angle deviation of the cutting bevel, and improving the consistency of the bevel angles of each steel pipe. After the alignment is completed, the steel pipe is tightened again by the clamping mechanism 3, and then the lifting and oblique cutting mechanism 4 is used to carry out batch cutting operations. Compared with the prior art, the cutting device can complete the angle cutting of multiple steel pipes in a single cutting, significantly improving the efficiency of bevel cutting, and fully meeting the process and technical index requirements for batch bevel cutting of steel pipes.

[0023] Combination Figure 1 and Figure 3 As shown, a driving motor 11 is fixedly installed on the left surface of the workbench 1, and the loading frame 2 includes a U-shaped frame A21 and a U-shaped frame B22. A plurality of connecting plates 23 are fixedly installed between the U-shaped frame A21 and the U-shaped frame B22, and a shaft rod 24 is inserted through the lower ends of the U-shaped frame A21 and the U-shaped frame B22. Bolts are installed between the shaft rod 24 and the U-shaped frame A21 and the U-shaped frame B22, and the shaft rod 24 is rotatably installed in the mounting cavity of the workbench 1. The output end of the driving motor 11 is fixedly connected to the left end of the shaft rod 24. The overall flipping action of the loading frame 2 is achieved by the coordinated operation of the shaft rod 24 and the driving motor 11.

[0024] Combination Figure 1 and Figure 3As shown, the clamping mechanism 3 includes a double-end output shaft motor 31, which is fixedly mounted on the rear surface of the rear end connecting plate 23, and the outer surfaces of the two output shafts of the double-end output shaft motor 31 are fixedly sleeved with a J-shaped pressure rod 32. The double-end output shaft motor 31 can drive the J-shaped pressure rod 32 to flip toward the upper end opening direction of the loading cavity of the loading rack 2 by its power output. When the loading rack 2 is full of steel pipes, the J-shaped pressure rod 32 can exert downward pressure on the uppermost steel pipe, and through this downward pressure, a plurality of steel pipes can be tightly fitted and firmly fixed.

[0025] In order to improve the clamping effect on the steel pipe, it is necessary to set the end of the J-shaped pressure rod 32 away from the double-end output shaft motor 31 to be arc-shaped. The arc-shaped surface can increase the contact area with the steel pipe, thereby improving the clamping effect.

[0026] like Figure 1 As shown, the positioning mechanism 5 includes a fixed frame 51, which is fixedly installed on the upper surface of the workbench 1, and a hydraulic telescopic rod 52 is fixedly installed in the fixed frame 51, and a push plate 53 is fixedly installed on the left end of the hydraulic telescopic rod 52. In order to facilitate the rotation of the carrier 2 to a vertical state with the workbench 1, two positioning blocks 12 are fixedly installed on the upper surface of the workbench 1. When the carrier 2 is erected perpendicular to the table surface of the workbench 1, the rear surface of the carrier 2 is in contact with the front surface of the positioning block 12, and the push plate 53 is facing the right side of the carrier 2. At this time, the hydraulic telescopic rod 52 is extended to enable the push plate 53 to contact with multiple longitudinally placed steel pipes in the carrier 2, and push the steel pipes to the inner wall of the left side of the loading cavity of the carrier 2 to perform the alignment work, thereby ensuring that the position and angle of each steel pipe in the cutting coordinate system are accurately fixed, effectively reducing the angle deviation of the cutting bevel angle, and improving the consistency of the bevel angles of each steel pipe.

[0027] Combination Figure 1 and Figure 2 As shown, the lifting oblique cutting mechanism 4 includes a hanging frame 41, the hanging frame 41 is fixedly mounted on the upper surface of the workbench 1, and a screw motor 411 is fixedly mounted on the upper surface of the hanging frame 41, a screw 412 is fixedly mounted on the output end of the screw motor 411, the screw 412 is rotatably mounted in the hanging frame 41, a mounting frame 42 is vertically slidably mounted in the hanging frame 41, the mounting frame 42 and the screw 412 are threadedly connected, and a cutting motor 43 is fixedly mounted inside one end of the mounting frame 42 away from the hanging frame 41 according to the requirements of the cutting angle, and a cutting disc 44 is fixedly mounted on the output end of the cutting motor 43;

[0028] The screw motor 411 can drive the mounting frame 42 to move vertically by driving the screw 412 to rotate, thereby driving the cutting motor 43 and the cutting disc 44 to move up and down, thereby achieving an angled cutting operation on the longitudinally arranged steel pipes.

[0029] Working principle: When in use, the material carrier 2 is turned over to Figure 1 state, then, multiple steel pipes are put into the loading cavity of the loading rack 2 in turn, and then, the driving motor 11 and the shaft 24 are used to cooperate to drive the loading rack 2 to flip backward. When the rear surface of the loading rack 2 is in contact with the front surface of the positioning block 12, it means that the loading rack 2 is perpendicular to the table surface of the workbench 1, and the multiple steel pipes are driven into the cutting area. At this time, the position of the loading rack 2 is kept unchanged, and the multiple steel pipes are aligned by the positioning mechanism 5. Then, the multiple steel pipes are clamped and fixed by the clamping mechanism 3. Finally, the cutting disk 44 of the lifting and oblique cutting mechanism 4 can be used to uniformly cut the multiple steel pipes from top to bottom. After cutting, the lifting and oblique cutting mechanism 4 is reset, and the driving motor 11 is used to flip the loading rack 2 to Figure 5 The state is that the clamping mechanism 3 is released to fix the steel pipe, and the cut steel pipe can be unloaded under the action of gravity.
