Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, and in particular to a device for welding oil pipes of an excavator boom. Background Technology

[0002] Excavator boom hoses are key pipeline components in the excavator's hydraulic system that transmit hydraulic oil. They are used to connect the hydraulic pump, boom cylinder, and control valve. The outer layer is often equipped with a protective layer to resist the impact of gravel, oil corrosion, and the effects of high and low temperatures during excavation operations, ensuring that there is no oil leakage or deformation under high pressure conditions. Excavator boom hoses often require welding during production.

[0003] Currently, most excavator boom hoses are often placed on the workbench for welding operations. The positioning structure of traditional devices is often rigidly connected to the workbench, which can only fix the hose at preset points. However, because excavator boom hoses are adapted to different boom structures, they often need to be welded in sections and spliced ​​at multiple angles. The fixed points cannot be adjusted with the welding path, and the hoses need to be moved frequently to adjust their positions. This not only easily leads to the displacement of the already positioned weld joints, but also makes it difficult to achieve continuous welding of hoses with complex shapes, increasing the risk of welding errors. Therefore, an excavator boom hose welding device is proposed. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems in the existing technology where the hydraulic hoses of excavator booms are often placed on the workbench for welding operations. The positioning structure of traditional devices is often rigidly connected to the workbench, which can only fix the hoses at preset points. However, because the hydraulic hoses of excavator booms are adapted to different boom structures, they often need to be welded in sections and spliced ​​at multiple angles. The fixed points cannot be adjusted with the welding path, and the hoses need to be moved frequently to adjust their positions. This not only easily leads to the displacement of the already positioned weld joints, but also makes it difficult to achieve continuous welding of hoses with complex shapes, increasing the risk of welding errors. Therefore, this utility model proposes an excavator boom hose welding device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a welding device for the hydraulic hose of an excavator boom, comprising a workbench, a support plate fixedly connected to the lower surface of the workbench, a positioning assembly provided on the upper surface of the workbench, the positioning assembly including a sliding groove and a mounting plate, the sliding groove being located on the upper surface of the workbench, the mounting plate being located above the workbench, two symmetrically arranged rotating rods rotatably connected to the lower surface of the mounting plate, one end of each rotating rod being inserted into the sliding groove, and a carrier plate rotatably connected to the upper surface of the mounting plate, the upper surface of the carrier plate being fixed. The mounting plate is connected to a positioning block, and a restraining strap is fixedly connected to one side of the positioning block. A guide sleeve is fixedly connected to the upper surface of the carrier plate, and one end of the restraining strap passes through the guide sleeve. The mounting plate cooperates with the slide groove and guide groove of the worktable through the rotating rod and the rotating wheel. It can move and adjust its position flexibly along the slide groove without the need for additional drilling, welding or other modifications to the worktable or front axle. It also supports the independent assembly and fixing of multiple sets of mounting plates. According to the welding path of the excavator boom oil pipe, fixing points can be set at different positions on the worktable, which can easily meet the multi-position operation needs such as long oil pipe segment welding and multi-angle splicing of complex-shaped oil pipes.

[0006] Furthermore, the workbench has a guide groove inside, which is connected to a slide groove. The lower end of the rotating rod extends into the guide groove, and a rotating wheel is rotatably connected to the lower end of the rotating rod. The rotating wheel is slidably connected to the inner wall of the guide groove, which facilitates the adjustment of the position of the mounting plate.

[0007] Furthermore, a limiting sleeve is fixedly connected to the upper surface of the guide sleeve, the interior of the limiting sleeve is connected to the guide sleeve, a pressure block is slidably connected to the inner wall of the limiting sleeve, an adjusting bolt is rotatably connected to the upper surface of the pressure block, and the adjusting bolt is threadedly connected to the inner wall of the limiting sleeve to facilitate tightening the binding strap.

[0008] Furthermore, a stabilizing plate is fixedly connected to one side of the mounting plate, and a threaded sleeve is fixedly connected to the upper surface of the stabilizing plate. A locking bolt is threaded onto the inner wall of the threaded sleeve, and one end of the locking bolt penetrates the stabilizing plate. The adjustment of the carrier plate angle and the fixing of the oil pipe do not require complicated tools. The overall operation process is simple and easy to understand, and can be quickly mastered without professional technicians. When changing the specifications of the welded oil pipe or adjusting the welding position, it is not necessary to disassemble the entire device. Only the position of the corresponding mounting plate or the angle of the carrier plate needs to be adjusted separately, which greatly shortens the equipment debugging and operation preparation time, improves the batch welding efficiency of the excavator boom oil pipe, and reduces the intensity of manual operation and time costs.

[0009] Furthermore, two symmetrically arranged magnets are mounted on the upper surface of the mounting plate. The magnets are located on the movement trajectory of the carrier plate and are used to assist in positioning the carrier plate when it is idle.

[0010] Furthermore, a vertical tie rod is fixedly connected to the upper surface of the carrier plate. The angle of the carrier plate can be directly adjusted by the tie rod, which can quickly adapt to the welding posture of the excavator boom oil pipe with different diameters and different curvatures without the need to replace the special positioning fixture.

[0011] Furthermore, an anti-slip pad is fixedly connected to the upper surface of the carrier plate. The anti-slip pad is located below the binding strap. A pull block is fixedly connected to the end of the binding strap away from the positioning block. The anti-slip pad increases the friction between the oil pipe and the carrier plate, preventing the oil pipe from sliding during angle adjustment. This further improves the positioning accuracy of oil pipes of different specifications and reduces welding deviations caused by fixture compatibility issues.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the mounting plate cooperates with the sliding groove and guide groove of the workbench through the rotating rod and rotating wheel. It can be flexibly moved and adjusted along the sliding groove without the need for additional drilling, welding or other modifications to the workbench or front axle. It also supports the independent assembly and fixing of multiple sets of mounting plates. According to the welding path of the excavator boom oil pipe, fixing points can be set at different positions on the workbench, which can easily meet the multi-position operation needs such as segmented welding of long oil pipes and multi-angle splicing of complex-shaped oil pipes.

[0013] 2. In this utility model, the adjustment of the carrier plate angle and the fixing of the oil pipe do not require complicated tools. The overall operation process is simple and easy to understand. No professional technicians are required to get started quickly. When changing the specifications of the welding oil pipe or adjusting the welding position, it is not necessary to disassemble the entire device. Only the position of the corresponding mounting plate or the angle of the carrier plate needs to be adjusted separately. This greatly shortens the equipment debugging and operation preparation time, improves the batch welding efficiency of the excavator boom oil pipe, and reduces the intensity of manual operation and time costs.

[0014] 3. In this utility model, the angle of the carrier plate can be directly adjusted by the pull rod, which can quickly adapt to the welding posture of the excavator boom oil pipe with different diameters and different curvatures without the need to replace the special positioning fixture. At the same time, the anti-slip pad increases the friction between the oil pipe and the carrier plate, preventing the oil pipe from sliding during the angle adjustment process, further improving the positioning accuracy of oil pipes of different specifications, and reducing welding deviations caused by fixture compatibility issues.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a welding device for the hydraulic hose of an excavator boom, including a workbench 1, a support plate 2 fixedly connected to the lower surface of the workbench 1, and a positioning component 3 provided on the upper surface of the workbench 1. The positioning component 3 includes a sliding groove 33 and a mounting plate 31. The sliding groove 33 is located on the upper surface of the workbench 1, and the mounting plate 31 is located above the workbench 1. Two symmetrically arranged rotating rods 34 are rotatably connected to the lower surface of the mounting plate 31, with one end of each rotating rod 34 inserted into the sliding groove 33. A carrier plate 318 is rotatably connected to the upper surface of the mounting plate 31, and a positioning block 310 is fixedly connected to the upper surface of the carrier plate 318. A restraint strap 311 is fixedly connected to one side of the 10, and a guide sleeve 314 is fixedly connected to the upper surface of the carrier plate 318. One end of the restraint strap 311 passes through the guide sleeve 314. The mounting plate 31 cooperates with the slide groove 33 and guide groove 32 of the workbench 1 through the rotating rod 34 and the rotating wheel 35. It can move and adjust its position flexibly along the slide groove 33 without the need for additional drilling, welding or other modifications to the workbench 1 or the front axle. It also supports the independent assembly and fixing of multiple sets of mounting plates 31. According to the welding path of the excavator boom oil pipe, fixing points can be set at different positions on the workbench 1, which can easily meet the needs of multi-position operation such as segmented welding of long oil pipes and multi-angle splicing of complex-shaped oil pipes.

[0018] The workbench 1 has a guide groove 32 inside, which is connected to the slide groove 33. The lower end of the rotating rod 34 extends into the guide groove 32, and the lower end of the rotating rod 34 is rotatably connected to a rotating wheel 35. The rotating wheel 35 is slidably connected to the inner wall of the guide groove 32, which facilitates the adjustment of the position of the mounting plate 31.

[0019] Among them, the upper surface of the guide sleeve 314 is fixedly connected to the limiting sleeve 315, the interior of the limiting sleeve 315 is connected to the guide sleeve 314, the inner wall of the limiting sleeve 315 is slidably connected to the pressure block 316, the upper surface of the pressure block 316 is rotatably connected to the adjusting bolt 317, and the adjusting bolt 317 is threadedly connected to the inner wall of the limiting sleeve 315 to facilitate the tightening of the restraint band 311.

[0020] The mounting plate 31 is fixedly connected to a stabilizing plate 319 on one side. A threaded sleeve 37 is fixedly connected to the upper surface of the stabilizing plate 319. A locking bolt 38 is threadedly connected to the inner wall of the threaded sleeve 37. One end of the locking bolt 38 passes through the stabilizing plate 319. The angle adjustment of the carrier plate 318 and the fixing of the oil pipe do not require complicated tools. The overall operation process is simple and easy to understand. No professional technicians are required to get started quickly. When changing the specifications of the welding oil pipe or adjusting the welding position, it is not necessary to disassemble the entire device. Only the position of the corresponding mounting plate 31 or the angle of the carrier plate 318 needs to be adjusted separately. This greatly shortens the equipment debugging and operation preparation time, improves the batch welding efficiency of the excavator boom oil pipe, and reduces the intensity of manual operation and time costs.

[0021] Two symmetrically arranged magnets 36 are mounted on the upper surface of the mounting plate 31. The magnets 36 are located on the movement trajectory of the carrier plate 318 and are used to assist in positioning the carrier plate 318 when it is idle.

[0022] The upper surface of the carrier plate 318 is fixedly connected with a vertical tie rod 39. The angle of the carrier plate 318 can be directly adjusted by the tie rod 39, which can quickly adapt to the welding posture of the excavator boom oil pipe with different diameters and different curvatures without the need to replace the special positioning fixture.

[0023] Among them, an anti-slip pad 312 is fixedly connected to the upper surface of the carrier plate 318. The anti-slip pad 312 is located below the binding strap 311. A pull block 313 is fixedly connected to the end of the binding strap 311 away from the positioning block 310. The anti-slip pad 312 increases the friction between the oil pipe and the carrier plate 318, prevents the oil pipe from sliding during the angle adjustment process, further improves the positioning accuracy of oil pipes of different specifications, and reduces welding deviations caused by fixture compatibility issues.

[0024] Working principle: First, the mounting plate 31 is assembled and fixed. The rotating rod 34 on the lower surface of the mounting plate 31 is aligned with the slide groove 33 of the worktable 1 and inserted. At the same time, the rotating wheel 35 at the lower end of the rotating rod 34 enters the guide groove 32 that communicates with the slide groove 33, completing the initial positioning of the mounting plate 31. After pushing the mounting plate 31 along the slide groove 33 to the position required for oil pipe welding, the locking bolt 38 in the threaded sleeve 37 on the stabilizing plate 319 on one side of the mounting plate 31 is tightened, so that one end of the locking bolt 38 abuts against the surface of the worktable 1. The mounting plate 31 is fixed by friction, preventing the mounting plate 31 from shifting during the welding process. Next, the angle of the carrier plate 318 is adjusted by pulling the pull rod 39 to adapt to the welding posture of oil pipes of different specifications. When the carrier plate 318 is rotated to the target angle, the excavator boom oil pipe to be welded is placed on the anti-slip pad 312 on the upper surface of the carrier plate 318. Pull the binding strap 311 on one side of the positioning block 310 to pass the binding strap 311 over the oil pipe and through the guide sleeve 314. Pull the binding strap 311 with the pull block 313 to initially press the oil pipe onto the carrier plate 318. Then, turn the adjusting bolt 317 in the upper limit sleeve 315 of the guide sleeve 314. The adjusting bolt 317 drives the pressure block 316 to slide down along the inner wall of the limit sleeve 315 to further press the binding strap 311 through the guide sleeve 314, so as to achieve a firm fixation of the oil pipe and prevent the oil pipe from shifting during the welding process and affecting the welding accuracy. If multi-position welding of oil pipes is required, the above steps can be repeated to install multiple sets of mounting plates 31. Each set of mounting plates 31 is independently positioned by the cooperation of the rotating rod 34, the rotating wheel 35, the sliding groove 33, and the guide groove 32. They are fixed to different positions on the workbench 1 by locking bolts 38. Each set of carrier plates 318 can be adjusted in angle and the oil pipe can be fixed independently. Since the position of the mounting plate 31 can be flexibly adjusted along the sliding groove 33 and the angle of the carrier plate 318 can be adapted as needed, it can ultimately meet the multi-position welding requirements of oil pipes of different specifications of excavator booms, ensuring stable welding operation and strong adaptability.
