Description
Technical Field
[0001] This utility model relates to the field of end cap processing technology, and in particular to a large end cap splicing and welding positioning device. Background Technology
[0002] An end cap is a component used to seal the end of a container, isolating it from the internal and external media; it is also called an end cover. End caps of cylindrical containers are generally rotating shells. Based on the shape of their surface, end caps can be classified as convex, conical, flat, and combined types. Convex end caps are those with a convex outer surface, such as hemispherical, elliptical, dished, and spherical end caps without folded edges. Some gas cylinders use combined bottom end caps with the convex surface facing inwards, which ensures both strength and safety requirements.
[0003] The end cap is connected to the cylinder by welding. Before welding, the end cap and the cylinder need to be centered to keep the edges flush, thereby ensuring the quality of the weld.
[0004] When welding the existing end cap to the cylinder, hoisting equipment is needed to lift the cylinder directly above the end cap. Since the cylinder will sway during the hoisting and movement, manual guidance and positioning are required, which is not only labor-intensive but also dangerous.
[0005] Therefore, it is necessary to provide a large head splicing and welding positioning device to solve the above-mentioned technical problems. Utility Model Content
[0006] This utility model provides a large-scale head splicing and welding positioning device, solving the problem that the cylinder will sway during hoisting and movement, requiring manual guidance for positioning, which is not only labor-intensive but also dangerous. To solve the above technical problem, this utility model provides a large-scale head splicing and welding positioning device, including a workbench. A rectangular groove is formed on the top of the workbench. A baffle is fixedly installed on the inner wall of the right end of the rectangular groove. A pushing component is installed on the side wall of the baffle. The pushing component is connected to an arc-shaped cover. An end cap is inserted into the inner wall of the arc-shaped cover. A lifting component is installed at the center of the top of the workbench. A limiting cylinder is installed on the top of the lifting component. A conical cylinder is fixedly installed on the top of the limiting cylinder. A cylinder body is inserted into the inner wall of the limiting cylinder. A moving component is installed at the bottom of the lifting component. A welding device is connected to the moving component. A limiting block is installed on the outer wall of the upper end of the cylinder body.
[0007] Preferably, the pushing component includes a cylinder, which is fixed to the side wall of the baffle. The output end of the cylinder passes through the baffle, and a slider is fixedly installed at the output end of the cylinder. The side wall of the slider is slidably connected to the inner wall of the rectangular groove, and the top of the slider is connected to the arc-shaped cover.
[0008] Preferably, the lifting assembly includes electric actuators, and several sets of electric actuators are evenly fixed on the top of the worktable. A circular plate is fixedly installed between the output ends of each set of electric actuators. The top center of the circular plate is fixedly connected to a limiting cylinder, and the bottom of the limiting cylinder passes through the circular plate. The bottom of the circular plate is connected to a moving assembly.
[0009] Preferably, the moving component includes a slide rail, which is fixed to the bottom of the circular plate. A sliding device is slidably connected to the inner wall of the slide rail, and the bottom of the sliding device is fixedly connected to the welding device.
[0010] Preferably, a protrusion is fixedly installed on the top of the cylinder, and the protrusion is connected to the clamping device of the external hoisting equipment.
[0011] Preferably, the limiting block is annular and made of rubber.
[0012] Preferably, a control device is fixedly installed on the side wall of the workbench, and the control device is electrically connected to the electric actuator.
[0013] Compared with related technologies, the large head splicing and welding positioning device provided by this utility model has the following beneficial effects: By setting up the baffle, the center of the end cap will be aligned with the center of the cylinder after the slider contacts the baffle, thus achieving an automatic positioning effect. After the clamping device of the external hoisting equipment clamps the protrusion, it sends the cylinder to the top of the conical cylinder. Then, it releases the protrusion, and the cylinder automatically slides into the limiting cylinder along the conical cylinder. Under the action of the limiting block, it stops moving downward. Through the interaction of the above devices, automatic positioning and material receiving can be achieved. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please refer to the following: Figure 1 A schematic diagram of a preferred embodiment of a large head splicing and welding positioning device provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the cylinder. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of part B is shown. A large end cap splicing welding positioning device includes: a workbench 1, a rectangular groove 15 on the top of the workbench 1, a baffle 9 fixedly installed on the inner wall of the right end of the rectangular groove 15, a pushing component 5 installed on the side wall of the baffle 9, an arc-shaped cover 7 connected to the pushing component 5, an end cap 11 inserted into the inner wall of the arc-shaped cover 7, a lifting component 2 installed at the top center of the workbench 1, a limiting cylinder 3 installed on the top of the lifting component 2, a conical cylinder 4 fixedly installed on the top of the limiting cylinder 3, a cylinder body 10 inserted into the inner wall of the limiting cylinder 3, a moving component 13 installed at the bottom of the lifting component 2, a welding device 12 connected to the moving component 13, and a limiting block 14 installed on the outer wall of the upper end of the cylinder body 10.
[0018] The pushing component 5 includes a cylinder 51, which is fixed to the side wall of the baffle 9. The output end of the cylinder 51 passes through the baffle 9, and a slider 52 is fixedly installed at the output end of the cylinder 51. The side wall of the slider 52 is slidably connected to the inner wall of the rectangular groove 15, and the top of the slider 52 is connected to the arc-shaped cover 7.
[0019] After the external hoisting equipment places the end cap 11 inside the arc-shaped cover 7, the output end of the cylinder 51 drives the slider 52 to move along the rectangular groove 15 toward the baffle 9. When the slider 52 contacts the baffle 9, the center of the end cap 11 will be aligned with the center of the cylinder 10.
[0020] The lifting assembly 2 includes electric push rods 21. Several sets of electric push rods 21 are evenly fixed on the top of the worktable 1. A circular plate 22 is fixedly installed between the output ends of each set of electric push rods 21. The top center of the circular plate 22 is fixedly connected to the limiting cylinder 3, and the bottom of the limiting cylinder 3 passes through the circular plate 22. The inner wall of the limiting cylinder 3 is fitted and connected to the outer wall of the cylinder 10. The bottom of the circular plate 22 is connected to the moving assembly 13.
[0021] When the cylinder 10 is inserted into the inner wall of the limiting cylinder 3, if the lower end of the cylinder 10 does not contact the top of the end cap 11, the output end of the electric push rod 21 will drive the circular plate 22 to move downward as a whole, so that the bottom of the cylinder 10 is in close contact with the top of the end cap 11.
[0022] The moving component 13 includes a slide rail 132, which is fixed to the bottom of the circular plate 22. The slide rail 132 is annular, and a sliding device 131 is slidably connected to the inner wall of the slide rail 132. The bottom of the sliding device 131 is fixedly connected to the welding device 12.
[0023] The sliding device 131 can drive the welding device 12 to rotate and weld along the connection between the end cap 11 and the cylinder 10 via the slide rail 132.
[0024] A protrusion 8 is fixedly installed on the top of the cylinder 10, and the protrusion 8 is connected to the clamping device of the external hoisting equipment.
[0025] After the clamping device of the external hoisting equipment clamps the protrusion 8, it sends the cylinder 10 to the top of the conical cylinder 4. Then it releases the protrusion 8, and the cylinder 10 automatically slides into the limiting cylinder 3 along the conical cylinder 4 and stops moving downward under the action of the limiting block 14.
[0026] The limiting block 14 is circular and made of rubber, and the rubber limiting block 14 has a high friction effect.
[0027] A control device 6 is fixedly installed on the side wall of the workbench 1. The control device 6 is electrically connected to the electric push rod 21 and is a PLC controller.
[0028] The working principle of the large head splicing and welding positioning device provided by this utility model is as follows: After the external hoisting equipment places the end cap 11 inside the arc-shaped cover 7, the pushing component 5 will move the arc-shaped cover 7 containing the end cap 11 to directly below the cylinder 10. At the same time, the baffle 9 will assist the pushing component 5 in positioning the end cap 11. Then, the cylinder 10 will be sent to the top of the conical cylinder 4 by the clamping device of the external hoisting equipment, and then released. The cylinder 10 will automatically slide into the limiting cylinder 3 along the conical cylinder 4. It will stop moving down under the action of the limiting block 14. Then, the lifting component 2 will make a fine adjustment so that the bottom of the cylinder 10 is connected to the top of the end cap 11. Finally, the welding device 12 will rotate and weld around the connection between the end cap 11 and the cylinder 10 with the assistance of the moving component 13.
[0029] Compared with related technologies, the large head splicing and welding positioning device provided by this utility model has the following beneficial effects: By setting the baffle 9, after the slider 52 contacts the baffle 9, the center of the end cap 11 will be aligned with the center of the cylinder 10, thus achieving an automatic positioning effect. After the clamping device of the external hoisting equipment clamps the protrusion 8, it sends the cylinder 10 to the top of the conical cylinder 4. Then it releases the protrusion 8, and the cylinder 10 automatically slides into the limiting cylinder 3 along the conical cylinder 4. It stops moving down under the action of the limiting block 14. Through the interaction of the above devices, automatic positioning and material receiving can be achieved.
