Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 , the utility model provides a technical solution: a round pipe welding auxiliary device, comprising a workbench 1, and the workbench 1 is a rectangular structure;

[0021] The mobile docking mechanism 2 includes a mobile chute 203 and a fixed clamp 204. The mobile chute 203 is provided in the middle of the top of the workbench 1. The two fixed clamps 204 are movably provided in the middle of both sides of the top of the workbench 1. The two fixed clamps 204 are respectively installed with a tube 4 inside.

[0022] Docking limit mechanism 3, the docking limit mechanism 3 includes a fixed block 304 and an electric push rod 305, the fixed block 304 is installed on the top of the fixed clamp 204 on the right side by bolts, and the two electric push rods 305 are respectively installed on the bottom end of the fixed clamp 204 on the left side and the middle of the fixed block 304 by bolts.

[0023] The mobile docking mechanism 2 also includes a mobile slider 201 and a bidirectional screw 202. The bidirectional screw 202 is installed in the middle of the inner cavity of the mobile slide 203 through a bearing. The two mobile sliders 201 are screwed on both ends of the bidirectional screw 202 respectively. The top of the mobile slider 201 is connected to the bottom end of the fixed clamp 204 by a bolt. In this way, after the tube bodies 4 on both sides are fixed by the fixed clamp 204, the bidirectional screw 202 is rotated to drive the mobile sliders 201 on both sides to move to the opposite side, and drive the fixed clamp 204 and the tube body 4 to move to the opposite side, so that the opposite ends of the tube bodies 4 on both sides are in contact and fixed;

[0024] The right end of the bidirectional screw 202 passes through the right side of the movable slide 203 and an operating handle is installed by a bolt. The right side of the inner cavity of the movable slide 203 is provided with a rotation hole at a position relative to the bidirectional screw 202, and the middle part of the movable slider 201 is provided with a mounting screw hole 6. In this way, the movable slider 201 is installed to the two ends of the bidirectional screw 202 through the mounting screw holes 6, and the bidirectional screw 202 is driven to rotate by the operating handle;

[0025] The docking limit mechanism 3 also includes a docking limit block 301, a mounting ball 302 and a fixed rod 303. The two fixed rods 303 are respectively mounted on opposite ends of the electric push rods 305 on both sides by bolts. The two docking limit blocks 301 are respectively mounted on opposite ends of the fixed rods 303 at the top and bottom ends by bolts. A plurality of mounting balls 302 are respectively movably mounted on the side of the docking limit block 301 away from the fixed rod 303.

[0026] The cross section of the docking limit block 301 is an arc-shaped structure. The docking limit block 301 is provided with an installation circular opening at the relative position of the installation ball 302. The electric push rod 305 is equipped with a switch. In this way, when the tube bodies 4 on both sides are welded and fixed, the tube bodies 4 on both sides are first contacted, and then the electric push rods 305 on both sides are started to drive the docking limit blocks 301 on both sides to move to the opposite side through the fixing rod 303, and the docking limit blocks 301 at the upper and lower ends are moved to the connection points of the tube bodies 4 on both sides, and the parts of the tube bodies 4 that need to be welded are limited and fixed and aligned. When the tube bodies 4 are rotated for welding, the installation ball 302 is driven to rotate. In the process of welding, not only the firmness of the weld is improved, but also the tube bodies 4 on both sides are more neat when docking, so as to avoid the misalignment of the weld when the tube bodies 4 on both sides are in contact and welding, which makes the requirements after welding not meet the standards and requires rework.

[0027] The docking limit block 301 and one side close to the fixed clamp 204 are both installed with a stabilizing slide bar 5 by bolts, and the fixed clamp 204 and the relative position of the stabilizing slide bar 5 are both provided with a stabilizing slide hole, and the stabilizing slide bar 5 is slidably connected to the inside of the stabilizing slide hole. In this way, when the docking limit block 301 moves, the stabilizing slide bar 5 is driven to slide inside the stabilizing slide hole, and the flexibility and stability of the docking limit block 301 when moving will be increased.

[0028] Working principle: After the utility model fixes the tube bodies 4 on both sides by fixing the clamps 204, the bidirectional screws 202 are rotated to drive the movable sliders 201 on both sides to move to the opposite side, and drive the fixed clamps 204 and the tube bodies 4 to move to the opposite side, so that the tube bodies 4 on both sides are in contact and fixed at one end. When the tube bodies 4 on both sides are welded and fixed, the tube bodies 4 on both sides are first made to contact, and then the electric push rods 305 on both sides are started to drive the docking limit blocks 301 on both sides to move to the opposite side through the fixed rods 303, and the docking limit blocks 301 at the upper and bottom ends move the connection points of the tube bodies 4 on both sides, and limit and fix the parts of the tube bodies 4 that need to be welded. When the tube bodies 4 are rotated for welding, the mounting balls 302 are driven to rotate, and in the process of welding, not only the firmness of the weld can be improved, but also the tube bodies 4 on both sides can be made more neat when docking, so as to avoid the misalignment of the welds when the tube bodies 4 on both sides are in contact and welding, which makes the requirements after welding fail to meet the standards and requires rework.
