Description

Technical Field

[0001] This utility model relates to the field of cone-shaped cylinder welding technology, specifically an automatic welding machine for longitudinal seams and circumferential seams of cone-shaped cylinders. Background Technology

[0002] The specialized welding machine for longitudinal and circumferential seams consists of a dedicated precision welding crossbeam, welding roller frames (including active and driven roller frames and a mechanical anti-slip mechanism), welding head, a rounding mechanism (supplied by the user), a welding power system, and a control system. During longitudinal seam welding of a cone-shaped structure, the workpiece is placed on the roller frame (larger diameter workpieces are placed at the rear end of the roller frame, and smaller diameter workpieces at the front end). The roller frame is tilted until the weld seam is horizontal. The welding head is mounted on a dedicated high-precision operating frame crossbeam slide support. The crossbeam slide moves to adjust the welding position. The crossbeam travels, causing the welding torch to move linearly. The back gas shielding crossbeam and welding torch move in tandem to provide back gas protection and form the weld seam, completing the longitudinal seam welding. Single-sided welding results in double-sided forming.

[0003] The cone is placed on a roller frame. During welding, the cone rotates due to the rotation of the rollers. However, the cone is tilted at this time. If the motor of one side of the roller malfunctions, the cone will experience uneven stress and may detach from the roller, causing a safety accident. Therefore, there is a need for a specialized automatic welding machine for the longitudinal seam of the cone and the longitudinal circumferential seam of the cylinder to solve the above problems.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this utility model is an automatic welding machine for longitudinal and circumferential seams of cone-shaped bodies and cylinders, comprising:

[0026] Welding manipulator 10 is fixed to the ground;

[0027] The welding head is controlled by a motor and a gear and rack transmission, which also supports the welding host, electrical control system and water tank.

[0028] The roller frame includes a base 20, a movable plate 21, a linear slide rail 22, a bracket 23, a first roller 24, and an L-shaped limiting rod 25. One end of the movable plate 21 is rotatably connected to the upper end of the base 20, the linear slide rail 22 is fixed to the upper end of the movable plate 21, the bracket 23 is slidably connected to the linear slide rail 22, the first roller 24 is rotatably connected to the upper end of the bracket 23, and one end of the L-shaped limiting rod 25 is fixed to the side of the movable plate 21.

[0029] The roller frame also includes a second roller 26, which is rotatably connected to the side of the L-shaped limiting rod 25 near the movable plate 21;

[0030] The movable rod 33 is movably connected to the upper end of the movable plate 21 and is located between the two first rollers 24;

[0031] The base 20 provides support, and one end of the movable plate 21 is rotatably connected to the base 20. The movable plate 21 is adjusted in angle by a hydraulic rod controlled by a hydraulic system. A lead screw is installed inside the linear slide rail 22. By rotating the external turntable, the lead screw is driven to rotate, causing the upper support 23 to move linearly. This, in turn, adjusts the relative or opposite movement of the first roller 24 on the linear slide rail 22. The L-shaped limit rod 25 provides a limiting function to prevent the cone from sliding down. The second roller 26 can reduce the frictional resistance when the cone rotates.

[0032] The limiting assembly includes a connecting block 31, a limiting groove 32, a movable rod 33, and a limiting plate 34. The connecting block 31 is fixed between two L-shaped limiting rods 25 and is located at the uppermost end. The limiting groove 32 is fixed above the connecting block 31. The movable rod 33 is inserted into the limiting groove 32. The limiting plate 34 is fixed at one end of the movable rod 33.

[0033] The limiting assembly also includes a connecting shaft 30, which is fixed between two L-shaped limiting rods 25 and located at the upper end. The connecting block 31 is rotatably connected to the connecting shaft 30.

[0034] The connecting block 31 is fastened to the connecting shaft 30 by a locking rod, and the movable rod 33 is fastened to the limiting groove 32 by a locking rod.

[0035] The connecting shaft 30 facilitates the rotation of the connecting block 31, the connecting block 31 provides support, the limiting groove 32 provides both support and limitation, and the movable rod 33 and the limiting plate 34 provide limitation.

[0036] Working principle:

[0037] Place the vertebral body on the roller frame and tilt the roller frame until the weld is horizontal. Push the movable rod 33 along the limiting groove 32 to push the movable rod 33 into the inner side of the vertebral body. When the limiting plate 34 is in contact with the connecting block 31, tighten the locking rod on the limiting groove 32. Rotate the connecting block 31 around the connecting shaft 30 to ensure that the movable rod 33 is not in contact with the inner wall of the vertebral body. Tighten the locking rod on the connecting block 31.

[0038] This step can prevent the motor from malfunctioning and causing the cone to detach when the first roller 24 rotates.

[0039] Please see Figure 3 This embodiment, based on the above embodiments, further includes:

[0040] The support assembly includes a support tube 40, a support rod 41, a universal joint 42, and a support plate 43. The support tube 40 is fixed to one end of the upper part of the base 20 near the L-shaped limiting rod 25. The support rod 41 is screwed into the support tube 40. The lower end of the universal joint 42 is fixed to the middle of the upper part of the support rod 41. The support plate 43 is fixed to the upper end of the universal joint 42.

[0041] The support assembly also includes an anti-slip pad 44, which is fixed to the upper end of the support plate 43 and adheres to the lower surface of the movable plate 21.

[0042] The support tube 40 and support rod 41 provide support, the universal joint 42 facilitates the adjustment of the angle of the support plate 43, and the anti-slip pad 44 has an anti-slip effect.

[0043] Working principle:

[0044] Place the cone on the roller frame, tilt the roller frame until the weld is horizontal, rotate the support rod 41 so that the support rod 41 moves upward along the support tube 40, driving the universal shaft 42 and the support plate 43 to move upward until the anti-slip pad 44 above the support plate 43 is in contact with the lower surface of the movable plate 21.

[0045] This step can provide support for the movable plate 21 and improve the stability of the movable plate 21 after the angle is adjusted.
