[0002] As one of the core components of a car, the quality and production efficiency of the automotive chassis assembly directly affect the vehicle's performance and market competitiveness. Traditional chassis assembly welding operations mostly employ manual welding or automated welding methods at fixed workstations. However, these methods have many shortcomings in practical applications.

[0003] Manual welding is highly dependent on the welder's skill level and experience, making it difficult to guarantee consistent welding quality. At the same time, manual welding is relatively inefficient, making it difficult to meet the needs of large-scale, high-efficiency production. In addition, manual welding poses safety hazards, such as arc radiation and spatter injuries, which threaten the welder's health.

[0004] While fixed-station automated welding improves welding quality and production efficiency to some extent, it still has the problem of material loading and unloading conflicts. That is, at a fixed station, welding operations and material loading and unloading operations often need to be carried out in the same space, which leads to an inefficient workflow and limited production efficiency.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] See Figure 1-3 As shown, a welding machine for processing automotive frame assemblies includes a base 1, a station drive module 2, a processing drive module 3, and a welding module 4. The station drive module 2 is disposed within the base 1. The processing drive module 3 is disposed on the station drive module 2 and can move back and forth on the station drive module 2 by being driven by the station drive module 2, thereby realizing the switching between different welding stations. The welding module 4 is disposed on the processing drive module 3 and can move back and forth on the processing drive module 3 by being driven by the processing drive module 3, thereby realizing the welding module 4 to weld different positions of the automotive frame assembly.

[0033] Further, see Figure 6-7 As shown, in this embodiment, the workstation drive module 2 includes a pair of first linear guides 21 and a rack 22; a connecting plate 23 is provided on the slide of the pair of first linear guides 21; the rack 22 is meshed with a gear 24, the gear 24 is sleeved on the output shaft of a first drive motor 25, and the first drive motor 25 is mounted on the lower end face of the connecting plate 23 via a first motor bracket 26; during installation, see... Figure 4 As shown, a pair of first linear guides 21 and a rack 22 are both fixed on the base 1. At this time, the pair of first linear guides 21 and rack 22 are parallel to each other, and the rack 22 is located between the pair of first linear guides 21. The processing drive module 3 is disposed on the upper surface of the connecting plate 23. During operation, the first motor bracket 26 drives the gear 24, thereby driving the connecting plate 23 to move along the pair of first linear guides 21, thereby driving the processing drive module 3 to switch between different welding stations.

[0034] In this embodiment, to prevent a hard collision between the connecting plate 23 and the base 1 during the workstation transition, which could lead to excessive noise and affect the service life of the welding machine, see [reference needed]. Figure 4-6As shown, a buffer 27 is provided on one side of the front and rear ends of a pair of first linear guide rails 21. The buffer 27 is respectively mounted on the base 1 through a corresponding support seat. During operation, the buffer 27 cooperates with the side wall of the connecting plate 23 to buffer and decelerate the moving connecting plate 23 to a stop, thereby reducing noise and increasing the service life of the welding while improving the efficiency and stability of the work station.

[0035] Further, see Figure 8-9 As shown, in this embodiment, the processing drive module 3 includes a pair of second linear guides 31. A fixed seat 32 is provided on the slide of the pair of second linear guides 31. A ball screw 33 is provided directly below the fixed seat 32. The balls of the ball screw 33 are connected to the fixed seat 32 through a connecting seat 34. The two ends of the ball screw 33 are respectively provided on the connecting plate 23 through a bearing seat 35. One end of the ball screw 33 is connected to a second drive motor 37 through a coupling 36. The second drive motor 37 is provided on the bearing seat 35 on the corresponding side through a second motor bracket 38. During installation, refer to [link to installation instructions]. Figure 8 As shown, a pair of second linear guides 31 and the bearing seat 35 are both fixed on the connecting plate 23. At this time, the ball screw 33 is parallel to the pair of second linear guides 31. The welding module 4 is set on the fixed seat 32. During operation, the second drive motor 37 drives the screw to rotate through the coupling 36, thereby driving the balls to move along the screw, thereby displacing the fixed seat 32, thereby moving the welding module 4 installed on the fixed seat 32, and thus realizing welding at different positions of the automobile frame assembly.

[0036] In this embodiment, see Figure 8 As shown, the fixing base 32 includes an upper fixing plate 321 and a lower fixing plate 322 spaced apart. The front and rear ends of the upper fixing plate 321 and the lower fixing plate 322 are connected by a connecting block 323, thereby forming a channel between the upper fixing plate 321 and the lower fixing plate 322. During installation, the lower fixing plate 322 is connected to the slide of a pair of second linear guide rails 31, and the welding module 4 is disposed on the upper fixing plate 321.

A welding device 43 is provided at the end of the articulated arm robot 41. During installation, the welding module 4 is fixed to the upper fixing plate 321 by the robot base 4. During operation, the welding device 43 performs welding operations under the drive of the articulated arm robot 41.

[0038] Further, see Figure 1 As shown, in this embodiment, a protective plate 5 is provided at the upper end of the base 1. The protective plate 5 passes through the channel formed between the upper fixed plate 321 and the lower fixed plate 322. By setting the protective plate 5, the various components set in the base 1 are protected while improving the aesthetics. A support foot 6 is provided on the lower end surface of the base 1. By setting the support foot 6, the height of the welding machine can be adjusted to adapt to different ground conditions, while reducing vibration and noise generated during operation.

[0039] The working principle of this utility model is as follows:

[0040] See Figure 11 As shown, taking a dual-station example, E in the diagram represents the fixture; F represents the vehicle frame assembly; and G represents the welding machine. During welding, after the vehicle frame assembly is installed in the fixture, the welding machine is started. First, the station drive module 2 drives the processing drive module 3 and the welding module 4 to move together to one of the processing stations. The welding module 4 then welds the areas of the vehicle frame assembly that need welding within this area. After welding is completed in this area, the processing drive module 3 drives the welding module 4 to move to the next welding point to continue welding until all welding of the vehicle frame assembly is completed. At the same time, the processing drive module 3 drives the welding module 4 to move back to the initial position, and the station drive module 2 drives the processing drive module 3 and the welding module 4 to move together to the other processing station for welding. After the vehicle frame assembly in the welding station is completed, the operator unloads the vehicle frame assembly from the fixture and reloads a new vehicle frame assembly to be welded into the fixture, ready for the next round of welding operations.
