[0002] The workpieces sent by customers, such as the inner partitions of aluminum alloy oil tanks, need to be welded with circumferential seams. When loading, the workpieces need to be manually hoisted to the clamping mechanism and automatically clamped. The workpieces are positioned in the up and down directions by the servo motor drive assembly to move the workpieces to the end positioning assembly, and the workpieces are confirmed to be in place by means of torque or detection switches. Because the workpieces are large in size and the workstation adopts a multi-station design, it is currently difficult to load the workpieces by forklifts, the loading space is small, and the steering operation is difficult; and when the workpieces are loaded by external clamping, they are prone to collision with the clamping part of the circumferential seam welding workstation, so it is necessary to customize and improve the design for loading cylindrical oil tank workpieces.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention.

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0015] like Figure 1~2As shown, a cylindrical workpiece hoisting and loading system includes a gantry frame 1, a balance hanger 2 and an inner support hanger 3. The upper end of the gantry frame 1 is provided with a first track 11 along the X direction, and the lower end of the first track 11 is movably installed with a second track 12 along the Y direction. The balance hanger 2 is movably connected to the lower end of the second track 12. The inner support hanger 3 is hoisted below the balance hanger 2. The inner support hanger 3 includes a frame 31, a cylinder 32, a connecting rod 33, a chassis 34, a guide rail 35 and an inner support rod 36. The cylinder 32 is installed in the frame 31, and the output end of the cylinder 32 is vertically arranged downward, the chassis 34 is installed at the lower end of the frame 31, the chassis 34 is arranged at the lower end of the frame 31, the fork of the chassis 34 extends to the outside of the frame 31, and the guide rails 35 are installed on the fork of the chassis 34 one by one, the inner support rod 36 is movably connected with the guide rail 35 and installed on the chassis 34, and one end of the connecting rod 33 is hinged with the output end of the cylinder 32, and the other end is hinged with the inner support rod 36. Specifically, in this embodiment, the gantry frame 1 adopts a steel structure with low cost, high structural strength and good stability. The first and second tracks 11 and 12 are arranged above the gantry frame 1, so that the balance crane 2 can be displaced in the X direction and the Y direction, and one balance crane 2 can be used to match multiple welding positions, saving costs. The inner support hanger 3 is hoisted by a hook at the bottom of the balance hanger 2. The inner support hanger 3 extends from the top of the workpiece 100. At this time, the output end of the cylinder 32 extends downward, and through the connecting rod 33, drives the inner support rod 36 to slide outward along the guide rail 35, expand, and then abut against the inner wall of the workpiece 100. The friction between the inner support rod 36 and the workpiece 100 is used to hoist the workpiece, and move it along the X and Y directions to the welding station for welding operations. The loading operation is extremely simple and convenient. In this design, in order to avoid jamming, we connect the inner support rod 36 through the guide rail 35. Driven by the connecting rod 33, the inner support rod 36 performs reciprocating linear motion, and is extremely smooth when contracting or expanding. At the same time, in order to match multiple inner support rods 36, we design the chassis 34 to be divergent, and the corners are matched with the guide rails 35 extending outward. The upper end of the connecting rod 33 is hinged to the output end of the cylinder 32, and the lower end is hinged to the end of the inner support rod 36 to avoid jamming during movement. The frame 31 adopts a square frame structure, which is light in weight and has an opening at the fork of the corresponding chassis 34, which is convenient for the telescopic output of the connecting rod 33 and the inner support rod 36. Furthermore, the number of the inner support rods 36 described in this design is four, and the corresponding number of guide rails 35 and connecting rods 33 is also four. In other embodiments, other numbers of inner support rods 36 can be designed according to the inner wall shape of the workpiece, which is not specifically limited here.
[0016] like Figure 2As shown, the output end of the cylinder 32 is equipped with an insert plate 321, and the connecting rods 33 are movably connected to the insert plate 321 through a pin. Specifically, in this embodiment, further, we install a cross-shaped insert plate 321 at the output end of the cylinder 32 for connecting with the connecting rod 33, so as to avoid the connecting rod 33 being directly connected to the output shaft of the cylinder 32, and facilitate disassembly and replacement when the cylinder 32 fails.
[0017] like Figure 2 As shown, the inner support rod 36 includes a skeleton 361, a slider 362 and a rubber pad 363. The slider 362 is installed below the skeleton 361 by bolts. The slider 362 is movably connected to the guide rail 35. The connecting rod 33 is hinged to the skeleton 361 by a pin, and the outer end of the skeleton 361 is connected to the rubber pad 363. Specifically, in this embodiment, further, the skeleton 361 and the slider 362 are connected by bolts, and the connecting rod 33 is hinged to the upper end of the skeleton 361. When the connecting rod 33 is driven by the cylinder 32 to move up and down, it can drive the skeleton 361 to contract or expand along the guide rail 35. When the skeleton 361 expands outward, the rubber pad 363 abuts against the inner wall of the workpiece, and the flexible contact not only enhances the friction force, but also avoids scratching the inner wall of the workpiece, thereby ensuring the quality of the workpiece.
[0018] like Figure 1~2 As shown, a telescopic operating arm 4 is also included, and the upper end of the telescopic operating arm 4 is connected to the top of the frame 31. Specifically, in this embodiment, the lower end of the telescopic operating arm 4 is provided with a control console, which can control the lifting or lowering of the balance crane 2 and the contraction or expansion of the inner support sling 3, which is extremely convenient to operate and reduces the difficulty of loading materials for on-site loading operators.
[0019] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
