Description

Technical Field

[0001] This utility model relates to the field of welding technology and equipment, and in particular to automated welding equipment for passenger vehicle instrument panel beams. Background Technology

[0002] Automated welding equipment for passenger vehicle instrument panel crossbeams is a specialized piece of equipment used in automobile manufacturing to automate the welding of passenger vehicle instrument panel crossbeams. It typically includes a support platform, a rotary positioner, a welding machine, a PLC control cabinet, and tooling fixtures. For example, the support platform supports the entire equipment and the workpiece to be welded; the rotary positioner rotates the workpiece horizontally and tilts it, expanding the welding range; the welding machine uses an arc welding robot to weld the workpiece; the PLC control cabinet controls the movements of the rotary positioner and the welding machine, achieving automated process control; and the tooling fixtures clamp the various components of the instrument panel crossbeam, ensuring welding accuracy.

[0003] The fixing assembly precisely positions the instrument beam and the parts to be welded within the welding work area, ensuring that each workpiece is in the same position during welding. This guarantees the positional accuracy of the weld joint, contributing to uniform and consistent weld quality and reducing welding defects caused by positional deviations, such as weld misalignment and incomplete penetration. The core of the equipment is to automate the welding process, involving a series of welding technology-related technologies, including welding power source, welding torch, welding path planning, and welding parameter control. Simultaneously, the equipment's mechanical structure design, transmission system, and tooling fixtures fall under the category of equipment technology, aiming to provide a stable and precise implementation platform for the welding process. Through programming and sensor feedback, it precisely controls the movements of welding robots or other motion mechanisms, achieving precise control of parameters such as welding speed, position, and angle, ensuring the stability and consistency of weld quality. It also enables automated operation, fault diagnosis, and alarm functions, improving production efficiency and reliability.

[0004] In existing technologies, without fixed components, it is difficult to maintain the precise position of the instrument panel crossbeam and the parts to be welded during welding, which easily leads to positional deviations, resulting in inaccurate weld joint positions, weld seam offsets, and affecting welding quality. This requires a lot of rework and may even cause the workpiece to be scrapped. During the welding process, the workpiece may move or deform due to welding force and thermal stress, making it difficult to ensure that the welded instrument panel crossbeam meets the dimensional accuracy requirements. This, in turn, affects the assembly accuracy of the crossbeam with other automotive parts, leading to problems such as uneven instrument panel installation and uneven gaps. This affects the overall aesthetics and assembly quality of the automotive interior. Therefore, an automated welding equipment for passenger vehicle instrument panel crossbeams is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automated welding equipment for passenger vehicle instrument crossbeams, which aims to improve the problems of inaccurate positioning, reduced welding efficiency, and inability to guarantee welding quality stability in the existing technology.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the fixing effect is achieved through the operation of a double-headed cylinder. The fixing component can firmly fix the workpiece in the welding position, preventing the workpiece from flying out due to welding impact or other external forces during the welding process. This avoids workpiece splatter and injury to the operator, ensuring production safety. The stable fixing component can reduce collisions and friction between the workpiece and the welding equipment during the welding process, reducing the risk of equipment damage. At the same time, it also avoids accidents caused by loose workpieces, providing a safer working environment for the operator.

[0024] 2. In this utility model, the operation of the double-headed cylinder causes the support plate to move the connecting plate two, achieving the lifting effect. Different vehicle models have different instrument beam sizes and structures. The lifting component can adjust the height to adapt the equipment to the welding needs of workpieces with different wheelbases and instrument panel installation positions, reducing the cost of replacing equipment due to vehicle model iterations. When it is necessary to maintain components such as welding machines and rotary positioners, the lifting component can raise the relevant mechanisms to a high position or lower them to a low position, providing sufficient operating space, improving maintenance efficiency and reducing safety hazards. Traditional equipment requires manual adjustment of the welding torch height or workpiece position to adapt to different products, while the lifting component can preset multiple sets of height parameters through the program and switch production tasks with one click, greatly shortening the changeover time and improving the flexibility of the production line.

Mounting plate 10 provides stability for fixing block 1 2, allowing the double-headed cylinder 3 fixedly connected inside to output more stably.

[0038] Working Principle: When the instrument panel crossbeam of a passenger vehicle needs to be fixed, the double-headed cylinder 3 is activated, and its drive end retracts, driving the connecting plate 4, which is fixedly connected to it, to move. This, in turn, moves the fixing plate 7, which is fixed to the outer wall of the connecting plate 4, thus initially positioning and clamping the relevant components of the instrument panel crossbeam. Multiple limiting blocks 6 fixed to the left end of the fixing plate 5 limit and guide the fixing plate 7, which is placed on the left end of the fixing plate 5, ensuring accurate positioning. When disassembly is required, the double-headed cylinder 3 pushes the connecting plate 4 at its drive end, causing the connecting plate 4 to move in the opposite direction. This moves the connecting rod 9 connected inside the fixing plate 7, which acts as a limit. The stable fixing components can reduce collisions and friction between the workpiece and the welding equipment during welding, reducing the risk of equipment damage. At the same time, it also avoids accidents caused by loose workpieces, providing a safer working environment for operators.

[0039] When the instrument panel beam of a passenger vehicle needs to be raised or lowered, the double-headed cylinder 3 drives the connecting plate 4 to move, which in turn moves the support plate 11. This causes the connecting plate 12 and the fixing block 13 fixed at the top of the support plate 11 to move synchronously, providing support and positioning for the welded workpiece. At the same time, the mounting plates 10 installed on the left and right ends of the base plate 1 support the square box 14. The fixing block 15 can slide inside the square box 14. When the equipment welds instrument panel beams of different sizes or those requiring specific position adjustments, the fixing block 15 moves under force, compressing the spring 16 at the top. The spring 16 provides buffering and adaptive adjustment, allowing the fixing block 15 to flexibly adjust its position. Together with other components, it achieves precise adjustment and stable support for the height and position of the instrument panel beam, ensuring the smooth progress of subsequent welding work.
