Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe welding, and more specifically to a steel pipe clamping and welding tool. Background Art

[0002] Steel pipe welding is the process of welding steel pipes with the same inner and outer diameters into one piece, or welding pipes with different inner and outer diameters into one piece. In order to lengthen the pipe length, a welding fixture clamping table is required during welding to keep the side ends of the steel pipe in contact during the welding process.

[0003] Currently, before steel pipes are connected and welded, a clamping tool is required to fix the connection position of the two sections of steel pipes to ensure that the connection position remains stable during the welding process. Since the clamping position is fixed, the steel pipe needs to be manually rotated during the welding process to improve the comprehensiveness of the welding. However, the manual rotation operation is prone to deviations, resulting in weld leaks at the connection during the welding process, which requires re-welding the weld leak position. In addition, the manual adjustment accuracy is poor, which increases the welding time. In view of this, we propose a steel pipe clamping welding tool. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a steel pipe clamping welding tool to solve the technical problems that the current manual rotation operation is prone to deviation, resulting in weld leaks at the connection during the welding process, resulting in the need to re-weld the weld leak position, and the manual adjustment accuracy is poor, which increases the welding time.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a steel pipe clamping and welding tool, comprising two clamp bodies for clamping steel pipes, support members for supporting the steel pipes fixedly installed on both sides of the clamp bodies, and drive members for controlling the rotation of the steel pipes fixedly installed on opposite sides of the support members on both sides;

[0006] The driving member includes a base, two adjustment plates are rotatably mounted on the top of the base, and an adjustment member for adjusting the angle is threadedly connected between the two adjustment plates;

[0007] A driving motor is fixedly mounted on one side of the adjustment plate close to the support member, a rotating ring is fixedly mounted on the output end of the driving motor, and a resistance member that fits the outer wall of the steel pipe is fixedly mounted on the outer wall of the rotating ring.

[0008] The utility model can conveniently adjust the rotating rings on both sides to a position that fits the outer wall of the steel pipe through the design of the driving part. After the clamp body and the support part cooperate to clamp the steel pipe to a limit, the rotating ring can be controlled to rotate by the drive motor. The friction resistance of the contact between the resistance part and the steel pipe can drive the steel pipe to rotate, so that the welding point of the steel pipe can be automatically adjusted during the welding process. The steel pipe is kept rotating at a uniform speed under the action of friction rotation, which can reduce the phenomenon of welding leaks and improve the accuracy of rotation adjustment.

[0009] Preferably, the upper and lower side walls of the rotating ring are both provided with a locking groove, and the inner wall of the rotating ring is fixed with a connecting block flush with one side of the locking groove.

[0010] Preferably, the resistance member includes a resistance ring, and a limiting block combined with the positioning groove is integrally formed on the inner wall of the resistance ring, and the limiting block is connected to the connecting block by screws.

[0011] Preferably, a plurality of resistance strips are integrally formed on the outer wall of the resistance ring, and both side corners of the side ends of the resistance strips are configured as guide surfaces.

[0012] Preferably, two arc-shaped grooves are formed between the two ends of the resistance bar, and the two ends of the two arc-shaped grooves face opposite directions.

[0013] Preferably, the resistance ring is composed of two half rings, and the limit block is composed of two fixed blocks. A positioning block is fixed on the side of the fixed block on one side, and a positioning groove combined with the positioning block is opened on the side of the fixed block on the other side.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model can conveniently adjust the rotating rings on both sides to a position that fits the outer wall of the steel pipe through the design of the driving part. After the clamp body and the support part cooperate to clamp the steel pipe to a limit, the rotating ring can be controlled to rotate by the drive motor. The friction resistance between the resistance part and the steel pipe can drive the steel pipe to rotate, so that the welding point of the steel pipe can be automatically adjusted during the welding process. Under the action of friction rotation, the steel pipe is kept rotating at a uniform speed, which can reduce the phenomenon of welding leaks and improve the accuracy of rotation adjustment.

[0016] 2. The utility model can also quickly limit the position of the resistance member and the rotating ring through the combination of the limit block and the positioning groove. The screw connection between the connecting block and the limit block can achieve the effect of quick disassembly. At the same time, the resistance ring and the limit block are composed of two parts, which can be easily separated. After the limit block is separated from the positioning groove, it can be divided into two halves and removed. In this way, it is easy to replace when the resistance bar is worn and the friction resistance decreases, thereby improving the flexibility of structural coordination.

[0023] like Figures 1 to 5 As shown, the utility model relates to a steel pipe clamping and welding tool, comprising two clamp bodies 1 for clamping steel pipes, support members 2 for supporting the steel pipes are fixedly installed on both sides of the clamp body 1, and driving members 3 for controlling the rotation of the steel pipes are fixedly installed on the opposite sides of the support members 2 on both sides; through the cooperation of the clamp body 1 and the support member 2, the two sections of steel pipes can be clamped, supported and limited, and the control of the driving member 3 can make the steel pipe achieve the effect of self-rotation during the welding process.

[0024] The driving member 3 includes a base 301, and two adjustment plates 302 are rotatably installed on the top of the base 301. An adjustment member 303 for adjusting the angle is threadedly connected between the two adjustment plates 302; the adjustment plates 302 are rotatably connected to the base 301 to adjust the angle. The setting of the adjustment member 303 can fix the position of the adjustment plate 302 after adjusting its inclination angle, for example, by using a bidirectional screw in conjunction with a movable block to complete the adjustment of the angle between the two adjustment plates 302.

[0025] A driving motor 4 is fixedly installed on one side of the adjustment plate 302 close to the support member 2, and a rotating ring 5 is fixedly installed on the output end of the driving motor 4. A resistance member 6 that fits the outer wall of the steel pipe is fixedly installed on the outer wall of the rotating ring 5; the rotation of the rotating ring 5 is controlled by the driving motor 4 to make the resistance member 6 in contact with the steel pipe rotate, so that the steel pipe can be driven to rotate synchronously under the friction resistance of the contact, thereby achieving the effect of the steel pipe's self-rotation.

[0026] In an embodiment of the present utility model, the upper and lower side walls of the rotating ring 5 are provided with a locking groove 501, and the inner wall of the rotating ring 5 is fixed with a connecting block 502 flush with one side of the locking groove 501. The resistance member 6 includes a resistance ring 601, and the inner wall of the resistance ring 601 is integrally formed with a limit block 602 combined with the locking groove 501, and the limit block 602 and the connecting block 502 are connected by screws; the opening of the locking groove 501 can facilitate the insertion of the limit block 602, thereby limiting the installation position of the resistance member 6, and the combination of the limit block 602 and the connecting block 502 can fix the position of the resistance member 6, and such a structure is easy to disassemble.

[0027] In an embodiment of the present utility model, a plurality of resistance bars 7 are integrally formed on the outer wall of the resistance ring 601, and the side corners of the side ends of the resistance bar 7 are set as guide surfaces 701. Two arc grooves 702 are provided between the two ends of the resistance bar 7, and the two ends of the two arc grooves 702 face opposite directions; the design of the guide surface 701 can increase the contact surface when rotating in contact with the surface of the steel pipe, thereby increasing the resistance formed by friction, and the opening of the arc groove 702 can improve the bending deformation effect of the resistance bar 7, and further improve the fit between the resistance bar 7 and the surface of the steel pipe.

[0028] In an embodiment of the present utility model, the resistance ring 601 is composed of two half rings, and the limit block 602 is composed of two fixed blocks. A positioning block 603 is fixed on the side of the fixed block on one side, and a positioning groove 604 combined with the positioning block 603 is opened on the side of the fixed block on the other side; the resistance ring 601 and the limit block 602 are formed by combination and can be separated during disassembly to reduce the difficulty of disassembly, eliminating the need to disassemble the connecting part between the rotating ring 5 and the driving member 3, thereby improving the convenience of disassembly and assembly of the resistance member 6.

[0029] Working principle: This embodiment provides a steel pipe clamping and welding tool. When in use, the steel pipe is first placed between the clamp body 1 and the support member 2. Then the steel pipe can be clamped and limited by the clamp body 1. Then, the resistance members 6 on both sides can be adjusted to a position that fits the outer wall of the steel pipe by adjusting the driving member 3, so that the two can achieve an extrusion bonding effect. After completion, the two sections of steel pipe can be welded. After completing the welding of one point, the driving motor 4 can be started to control the rotation of the rotating ring 5, so that the friction between the resistance strip 7 on the surface of the resistance member 6 and the steel pipe can be increased. The action drives the steel pipe to rotate so that the steel pipe can automatically rotate to the next welding point. In this way, the uniformity of the welding points can be improved during the welding process, the quality of welding can be enhanced, and the phenomenon of leaking welds can be reduced. When the resistance bar 7 rubs against the steel pipe for a long time and causes surface wear, the limit block 602 can be removed from the positioning groove 501 by separating the connecting block 502 from the limit block 602, and then the resistance ring 601 can be divided into two halves for removal. Such a structural combination is easy to disassemble and assemble, which can reduce the difficulty of replacement, so that good friction resistance is maintained between the resistance member 6 and the steel pipe, thereby improving the welding speed of the steel pipe.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
