Description

Technical Field

[0001] The utility model relates to the technical field of skew steel pipe welding, in particular to a skew steel pipe welding device. Background Art

[0002] Steel pipe welding mainly fixes two steel pipes together by welding. During welding, it is necessary to keep the two steel pipes stable to facilitate the work of the staff and ensure the welding quality.

[0003] In some cases, the two steel pipes are not perpendicular to each other but have a certain inclination angle. When welding such skew steel pipes, it is not easy to fix and maintain the angle of the two steel pipes, which is not convenient for users.

[0004] In view of the above problems, an improved skew steel pipe welding device is now designed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a skew steel pipe welding device to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A skew steel pipe welding device includes two fixed frames. A fixed column is installed at the central position of one side wall of the fixed frame, and the fixed column is perpendicular to the fixed frame. A rotating disk is rotatably connected to the side wall of the fixed column. A telescopic mechanism for adjusting the distance between the two rotating disks is arranged between the two rotating disks. A fixing mechanism for fixing the rotating disk is arranged on the fixed frame. Two sliding grooves are opened on the side wall of the fixed frame away from the rotating disk. Two moving blocks are slidably connected to the inner wall of the fixed frame. A fixing rod cooperating with the sliding groove is horizontally installed on the side wall of the moving block away from the rotating disk. One end of the fixing rod away from the moving block passes through the sliding groove and is arranged on the side of the fixed frame away from the rotating disk. Two connecting plates are installed on the side walls of the fixing rods on the two moving blocks close to the central position of the fixed frame. The connecting plates are perpendicular to the fixing rods. A clamping rod for clamping the steel pipe is installed at one end of the connecting plate close to the central position of the fixed frame. The four clamping rods can cooperate with each other to stably clamp steel pipes of different sizes. A driving mechanism for driving the two moving blocks to move relatively is arranged inside the fixed frame.

[0008] As a further solution of the present utility model: The telescopic mechanism includes a first internal thread cylinder. Telescopic plates and sliding frames are respectively installed on the side walls of the two rotating disks. The telescopic plates are slidably connected to the inner walls of the sliding frames. The first internal thread cylinder is installed on the side wall of the sliding frame close to the telescopic plate. The inner wall of the first internal thread cylinder is rotationally connected with a second threaded rod through a thread. One end of the second threaded rod away from the sliding frame is installed with a first rotating block for facilitating the staff to rotate the second threaded rod. One end of the second threaded rod away from the first rotating block presses tightly against the side wall of the telescopic plate.

[0009] As a further solution of the present utility model: The fixing mechanism includes a second internal thread cylinder. The second internal thread cylinder is installed on the side wall of the fixed frame close to the rotating disk through a connecting block. The inner wall of the second internal thread cylinder is rotationally connected with a first threaded rod through a thread. One end of the first threaded rod close to the rotating disk is rotationally connected with a friction block for tightly pressing and fixing the side wall of the rotating disk. One end of the first threaded rod away from the friction block is installed with a third rotating block for facilitating the staff to rotate the first threaded rod.

[0010] As a further solution of the present utility model: The driving mechanism includes a rotating rod. The rotating rod is vertically arranged inside the fixed frame. Both ends of the rotating rod are rotationally connected to the inner wall of the fixed frame. One end of the rotating rod passes through the fixed frame and is installed with a second rotating block for driving the rotating rod to rotate. A bidirectional screw rod is installed on the side wall of the rotating rod. Two moving blocks are rotationally connected to two threads with opposite directions of the bidirectional screw rod. The moving blocks are threadedly connected with the bidirectional screw rod.

[0011] As a further solution of the present utility model: Support blocks are installed on the side walls of the fixed rods on the two moving blocks away from the central position of the fixed frame. One end of the support block close to the fixed frame slides along the side wall of the fixed frame.

[0012] As a further solution of the present utility model: Ball bearings for facilitating the movement of the moving block along the inner wall of the fixed frame are installed on the side wall of the moving block. The ball bearings are closely attached to the inner wall of the fixed frame.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] The utility model clamps a steel pipe through four clamping rods, which can stably clamp steel pipes of different sizes and improve the application range of the device.

[0017] The utility model drives two moving blocks to move relatively through a bidirectional screw rod. The moving blocks drive the fixed rods, connecting plates and clamping rods to move, so that the clamping rods clamp the steel pipe. Since the moving blocks cannot drive the bidirectional screw rod to rotate, the fixed rods, connecting plates and clamping rods will not move randomly, and the clamping rods can stably clamp and fix the steel pipe.

[0018] Through the rotation of the rotating disc and the telescoping of the telescoping plate, the utility model can arrange two fixed frames on two obliquely intersecting steel pipes with different included angles. At the same time, the pressing and fixing of the telescoping plate by the second threaded rod and the pressing and fixing of the side wall of the rotating disc by the friction block can achieve stepless adjustment without angle limitation, which is convenient for users to use.

Two moving blocks 7 are slidably connected to the inner wall of the fixed frame 1. A fixing rod 10 which is used in cooperation with the sliding groove 8 is horizontally installed on the side wall of the moving block 7 away from the rotating disc 6. One end of the fixing rod 10 away from the moving block 7 passes through the sliding groove 8 and is arranged on the side of the fixed frame 1 away from the rotating disc 6. Two connecting plates 11 are installed on the side wall of the fixing rods 10 on the two moving blocks 7 close to the central position of the fixed frame 1. The connecting plate 11 is perpendicular to the fixing rod 10. A clamping rod 12 for clamping the steel pipe is installed at one end of the connecting plate 11 close to the central position of the fixed frame 1. The four clamping rods 12 can cooperate with each other to stably clamp steel pipes of different sizes. Support blocks 9 are installed on the side walls of the fixing rods 10 on the two moving blocks 7 away from the central position of the fixed frame 1. One end of the support block 9 close to the fixed frame 1 slides along the side wall of the fixed frame 1. A driving mechanism for driving the two moving blocks 7 to move relatively is arranged inside the fixed frame 1.

[0026] The telescopic mechanism includes a first internal thread cylinder 3. Telescopic plates 2 and sliding frames 4 are respectively installed on the side walls of the two rotating discs 6. The telescopic plate 2 is slidably connected to the inner wall of the sliding frame 4. The first internal thread cylinder 3 is installed on the side wall of the sliding frame 4 close to the telescopic plate 2. A second threaded rod 21 is rotationally connected to the inner wall of the first internal thread cylinder 3 through threads. A first rotating block 5 for facilitating the staff to rotate the second threaded rod 21 is installed at one end of the second threaded rod 21 away from the sliding frame 4. One end of the second threaded rod 21 away from the first rotating block 5 presses tightly against the side wall of the telescopic plate 2.

[0027] The fixing mechanism includes a second internal thread cylinder 18. The second internal thread cylinder 18 is installed on the side wall of the fixed frame 1 close to the rotating disc 6 through a connecting block. A first threaded rod 17 is rotationally connected to the inner wall of the second internal thread cylinder 18 through threads. A friction block 19 for tightly pressing and fixing the side wall of the rotating disc 6 is rotationally connected to one end of the first threaded rod 17 close to the rotating disc 6. A third rotating block 16 for facilitating the staff to rotate the first threaded rod 17 is installed at one end of the first threaded rod 17 away from the friction block 19.

[0028] The driving mechanism includes a rotating rod 14 which is vertically arranged inside the fixed frame 1. Both ends of the rotating rod 14 are rotatably connected to the inner wall of the fixed frame 1. One end of the rotating rod 14 passes through the fixed frame 1 and is equipped with a second rotating block 15 for driving the rotation of the rotating rod 14. A bidirectional screw 13 is installed on the side wall of the rotating rod 14. The two moving blocks 7 are rotatably connected to two opposite threads of the bidirectional screw 13. The moving blocks 7 are threadedly connected to the bidirectional screw 13.

[0029] During use, the staff rotates the second rotating block 15. The second rotating block 15 drives the rotation of the rotating rod 14. The rotating rod 14 drives the rotation of the bidirectional screw 13. Under the action of the threads, the bidirectional screw 13 drives the two moving blocks 7 to move relatively. The moving blocks 7 drive the fixed rod 10 to move. The fixed rod 10 drives the connecting plate 11 to move. The connecting plate 11 drives the clamping rod 12 to move, so that the four clamping rods 12 clamp and fix or release the steel pipe.

[0030] The working principle of an obliquely intersecting steel pipe welding device:

[0031] First, rotate the first rotating block 5. The first rotating block 5 drives the rotation of the second threaded rod 21. Under the action of the threads, the second threaded rod 21 moves along the inner wall of the first internal threaded cylinder 3 to the side away from the sliding frame 4, so that the telescopic plate 2 can slide on the inner wall of the sliding frame 4. Then, rotate the third rotating block 16. The third rotating block 16 drives the rotation of the first threaded rod 17. Under the action of the threads, the first threaded rod 17 moves along the inner wall of the second internal threaded cylinder 18 to the side away from the rotating disc 6. The first threaded rod 17 drives the friction block 19 away from the rotating disc 6, so that the rotating disc 6 can rotate.

[0032] Then, put the clamping rods 12 on the two fixed frames 1 on the two obliquely intersecting steel pipes. The staff rotates the second rotating block 15. The second rotating block 15 drives the rotation of the rotating rod 14. The rotating rod 14 drives the rotation of the bidirectional screw 13. Under the action of the threads, the bidirectional screw 13 drives the two moving blocks 7 to approach each other. The moving blocks 7 drive the fixed rod 10 to move. The fixed rod 10 drives the connecting plate 11 to move. The connecting plate 11 drives the clamping rod 12 to move, so that the four clamping rods 12 clamp and fix the steel pipe.

[0033] While the fixed frame 1 is fixed, the rotating disc 6 will roll, and the telescopic plate 2 will move along the inner wall of the sliding frame 4. After the fixed frame 1 is fixed on the steel pipe, rotate the first rotating block 5 to make the second threaded rod 21 tightly press against the side wall of the telescopic plate 2, so that the telescopic plate 2 and the sliding frame 4 are fixed together. Rotate the third rotating block 16 to make the friction block 19 tightly press against the side wall of the rotating disc 6 to prevent the rotating disc 6 from rotating, so as to realize the fixation of the two obliquely intersecting steel pipes, facilitating the staff to weld the joint of the two steel pipes.

[0034] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
