Description

Technical Field

[0001] This utility model relates to the field of automotive longitudinal beam welding technology, specifically to a welding device for processing automotive longitudinal beams. Background Technology

[0002] Welding equipment refers to the equipment used to connect two or more metal materials together through welding processes. As a key part of the vehicle's load-bearing system, the longitudinal beam of an automobile is crucial to the vehicle's stability. Welding can enhance the load-bearing capacity of the longitudinal beam, enabling it to better withstand various impacts generated during vehicle operation. Furthermore, the welding process can ensure that the longitudinal beam is not easily deformed or broken when subjected to external forces, thereby guaranteeing the safety performance of the entire vehicle.

[0003] The existing welding equipment is equipped with only one workbench, which means that only one welding operation can be carried out at the same time, thus limiting the overall capacity of the production line.

[0004] For example, the automotive parts welding device disclosed in patent CN211305332U has only one load-bearing device and one welding mechanism, so welding can only be performed in one position. Other workpieces to be welded may have to wait, which leads to an extended production cycle and reduced work efficiency.

[0005] Therefore, it is necessary to invent a welding device for processing automotive longitudinal beams to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a welding device for processing automotive longitudinal beams, in order to solve the problem that welding operations can only be performed at one location in the current technology, while other workpieces to be welded may have to wait, resulting in a longer production cycle and reduced work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a welding device for processing automotive longitudinal beams, comprising a base, a first worktable, and a second worktable. A support frame is provided above the base, an X-axis transmission assembly is provided on the front side of the support frame, a Z-axis transmission assembly is provided above the base, a Z-axis sliding plate is provided on the Z-axis transmission assembly, a first worktable is provided on one side above the Z-axis sliding plate, and a second worktable is provided on the other side above the Z-axis sliding plate.

[0008] Preferably, the X-axis transmission assembly is provided with an X-axis sliding plate, and the X-axis transmission assembly and the X-axis sliding plate are slidably connected, enabling the welding torch to move precisely in the X-axis direction.

[0009] Preferably, a Y-axis transmission assembly is provided on the front side of the X-axis sliding plate, and a Y-axis sliding plate is provided on the Y-axis transmission assembly. The Y-axis transmission assembly and the Y-axis sliding plate are slidably connected, and the Y-axis transmission assembly and the Y-axis sliding plate can realize the precise movement of the welding torch in the Y-axis direction.

[0010] Preferably, a welding torch is provided on the front side of the Y-axis sliding plate. The welding torch can be moved and adjusted along the X-axis and Y-axis directions, increasing the flexibility of welding.

[0011] Preferably, the Z-axis transmission assembly and the Z-axis sliding plate are slidably connected, enabling precise vertical movement of the first and second worktables.

[0012] Preferably, both the first workbench and the second workbench are mounted on the Z-axis sliding plate by four bolts, with the first workbench located on one side of the second workbench for easy welding operations.

[0013] Preferably, upright plates are provided on the front and rear sides of the No. 1 and No. 2 workbenches. A cylinder is provided on one side wall of the upright plate, and a clamping plate is provided on the other side of the upright plate. The side wall of the clamping plate is connected to the output end of the cylinder. The clamping and releasing of the clamping plate is achieved by the extension and retraction movement of the cylinder, which facilitates the fixing of the automobile longitudinal beam.

[0014] Preferably, a guide rod is connected between the clamping plate and the upright plate and passes through the upright plate. The guide rod and the upright plate are slidably connected to ensure the stability of the clamping plate during movement.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This invention features two worktables (Worktable 1 and Worktable 2) on the Z-axis sliding plate. The two worktables constitute two working areas, allowing the welding torch to perform welding operations on one worktable while the other worktable can simultaneously perform loading or unloading operations. This parallel operation mode greatly improves production efficiency, reduces waiting time, and thus increases the utilization rate of the entire welding device. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The welding device for processing automotive longitudinal beams shown includes a base 1, a first worktable 10 and a second worktable 11. A stand 2 is provided above the base 1. An X-axis transmission assembly 3 is provided on the front side of the stand 2. A Z-axis transmission assembly 8 is provided above the base 1. A Z-axis sliding plate 9 is provided on the Z-axis transmission assembly 8. The first worktable 10 is provided on one side above the Z-axis sliding plate 9, and the second worktable 11 is provided on the other side above the Z-axis sliding plate 9.

[0026] An X-axis sliding plate 4 is provided on the X-axis transmission assembly 3, and the X-axis transmission assembly 3 and the X-axis sliding plate 4 are slidably connected. A Y-axis transmission assembly 5 is provided on the front side of the X-axis sliding plate 4, and a Y-axis sliding plate 6 is provided on the Y-axis transmission assembly 5. The Y-axis transmission assembly 5 and the Y-axis sliding plate 6 are slidably connected. A welding torch 7 is provided on the front side of the Y-axis sliding plate 6. The Z-axis transmission assembly 8 and the Z-axis sliding plate 9 are slidably connected.

[0027] The welding torch 7, under the action of the X-axis sliding plate 4 and the X-axis transmission assembly 3, can move smoothly and accurately along the X-axis. At the same time, under the action of the Y-axis transmission assembly 5 and the Y-axis sliding plate 6, the welding torch 7 can move smoothly and accurately along the Y-axis. Furthermore, the Z-axis transmission assembly 8 and the Z-axis sliding plate 9 enable the first worktable 10 and the second worktable 11 to move smoothly and accurately along the Z-axis. Thus, through the coordinated work of the X-axis, Y-axis and Z-axis, the welding torch 7 can move freely in three-dimensional space to achieve precise welding.

[0028] Workbench 10 and workbench 11 are both mounted on the Z-axis sliding plate 9 by four bolts. Workbench 10 is located on one side of workbench 11. Upright plates 12 are provided on the front and rear sides of workbench 10 and workbench 11. A cylinder 13 is provided on one side wall of the upright plate 12, and a clamping plate 14 is provided on the other side of the upright plate 12. The side wall of the clamping plate 14 is connected to the output end of the cylinder 13. A guide rod 15 is connected between the clamping plate 14 and the upright plate 12 and passes through the upright plate 12. The guide rod 15 and the upright plate 12 are slidably connected.

[0029] The No. 1 workbench 10 and No. 2 workbench 11 are set independently and can perform welding operations separately, which improves work efficiency. The cylinder 13 drives the clamping plate 14 to move, realizing the clamping and releasing of the automobile longitudinal beam. The guide rod 15 ensures the stability of the clamping plate 14 during the movement, avoiding the decline in welding quality caused by shaking.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figure 1-5 When using this utility model, first place the automotive longitudinal beam to be welded on workbench 10 and workbench 11 respectively, then start cylinder 13, and drive clamping plate 14 to move through the output end of cylinder 13, clamping the automotive longitudinal beam between clamping plates 14, ensuring that clamping plates 14 and automotive longitudinal beam are in close contact without shaking or slippage. After the position of automotive longitudinal beam is fixed, the welding torch 7 is moved to the starting welding position of automotive longitudinal beam on workbench 10 through the coordinated work of X-axis transmission assembly 3 and Y-axis transmission assembly 5. At the same time, the height of welding torch 7 is adjusted through Z-axis transmission assembly 8 to ensure that the distance between welding torch 7 and automotive longitudinal beam is appropriate.

[0032] Then, the welding torch 7 is started to begin the welding operation. As the X-axis sliding plate 4 and the Y-axis sliding plate 6 move, the welding torch 7 performs welding operations on the automotive longitudinal beam on the first worktable 10. After the welding of the automotive longitudinal beam on the first worktable 10 is completed, the welding torch 7 is lifted to an appropriate height through the Z-axis transmission assembly 8. Then, the welding torch 7 is moved to the starting welding position of the automotive longitudinal beam on the second worktable 11 through the X-axis transmission assembly 3.

[0033] When the welding torch 7 moves to the automotive longitudinal beam on the second workbench 11 for welding, the worker can remove the welded automotive longitudinal beam from the first workbench 10 and place a new automotive longitudinal beam to be welded. The previous clamping steps are repeated to ensure that the new longitudinal beam is fixed and stable. After the automotive longitudinal beam on the second workbench 11 is welded, the welding torch 7 is moved back to the starting welding position on the first workbench 10 through the X-axis transmission assembly 3. This process is repeated, and the welding torch 7 circulates between the first workbench 10 and the second workbench 11 to achieve continuous and efficient automotive longitudinal beam welding production.
