Description

Technical Field

[0001] This utility model relates to the field of auxiliary welding technology for automotive parts, and in particular to an auxiliary welding device applied to the rear floor and side panel assembly. Background Technology

[0002] In the automotive manufacturing industry, auxiliary welding equipment plays a crucial role in the welding process of the rear floor and side panel assemblies due to its high efficiency and precision. This equipment is specifically designed for welding operations on the rear floor and side panel assemblies of automobiles, aiming to improve welding efficiency, ensure welding quality, and reduce worker fatigue. It integrates advanced automation technology, a precise positioning system, and efficient welding processes, meeting the stringent standards of modern automotive manufacturing. Through an adjustable rotary conveyor mechanism, the workpiece is transported between the rotating rings on the production line, working in conjunction with the drive motor assembly and related components to achieve precise positioning and initial limiting. Subsequently, the ring welding frame and the moving base cooperate to complete the fine welding work, while anti-detachment grippers ensure the stability of the workpiece. After welding, the workpiece can be quickly replaced using the rotating rings on the production line.

[0003] In practical applications, robotic arms used in auxiliary welding equipment are typically fixedly installed within the workshop. This fixed installation ensures the stability and precision of the welding operation. However, this fixed installation also limits the flexibility of the equipment, posing challenges when welding large workpieces or workpieces in different locations. When welding workpieces in different locations or large workpieces is required, the fixed nature of the robotic arm becomes a limiting factor, as it is difficult to move the robotic arm to the required position easily.

[0004] To address this issue, mobile equipment is sometimes used to move the robotic arm. However, this method also has drawbacks, particularly regarding the accuracy of the movement. Mobile equipment may cause the robotic arm to move to inaccurate positions due to factors such as uneven ground, tire wear, or operational errors. This inaccuracy directly affects the welding quality and may even lead to welding defects such as weld misalignment, undercut, and porosity. Utility Model Content

[0005] The main objective of this invention is to provide an auxiliary welding device for use in the rear floor and side panel assembly, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An auxiliary welding device for use in the rear floor and side panel assembly includes a platform, a mounting frame, a positioning fixture, and a support frame. The support frame is installed at the lower end of the platform, and multiple platforms are arranged in an array. The positioning fixture is installed on the platform through the mounting frame, and the positioning fixture is used to perform positioning and clamping operations on the rear floor and side panel assembly. The two rows of support frames are arranged in an array. The inner wall of the support frame has a notch. A limiting pulley is installed inside the notch. A moving track is connected between the two rows of support frames. The side wall of the moving track has a limiting groove that matches the limiting pulley. The moving track can be adjusted along the two rows of support frames by the limiting pulley and the limiting groove, so as to change the length of the moving track extending out of the platform. The upper end of the moving track is connected to a moving base, and a welding robot is installed on the upper end of the moving base. The upper end of the welding robot is connected to a welding gun through a connector. The welding robot drives the welding gun to move, so that it processes the rear floor and side panel assembly at the positioning fixture.

[0007] In a further alternative, two adjacent platforms are connected by a hinge device, and the platform is expanded outward by the hinge device to change the position of the platform and the positioning fixture. The outward expansion of the platform expands the expansion cavity to store the welding robot and the moving seat. In a further optional embodiment, the side wall of the support frame is provided with a lifting component, which is welded to the support frame and used to lift the support frame and the platform. The support frame and the platform are then welded and fixed. In a further alternative, the limiting pulley is mounted on the support frame via a rotating shaft. The edge of the limiting pulley is arc-shaped, and the opening of the limiting groove is arc-shaped. Two limiting grooves are symmetrically distributed on both sides of the moving track. The limiting grooves and the limiting pulley restrict the movement between the moving track and the support frame. In a further alternative, the upper end of the moving track is provided with a T-shaped groove, and the bottom of the T-shaped groove is provided with a screw hole. The moving seat is embedded in the T-shaped groove of the moving track and is adapted to the T-shaped groove. The moving seat and the moving track are fixed by bolts. In a further alternative, both the moving track and the support frame are provided with support feet at their lower ends to ensure stable placement of the moving track and the support frame. The lower end of the moving track is provided with a forklift slot for inserting a forklift to move the moving track.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The movable track can extend the platform between the support frames to the required length, adapting to welding operations of different sizes, making the equipment widely applicable to welding scenarios of various rear floor and side panel assemblies.

[0009] By sliding the limiting pulleys within the limiting grooves, the position of the moving track is precisely adjusted, ensuring accurate positioning of the welding robot at the positioning fixture and the welding operation. This stable and precise connection method not only improves welding quality but also extends the service life of the equipment.

[0010] The support frame provides a solid foundation for the entire equipment, ensuring stability during the welding process. Meanwhile, the design of the lifting components makes installation, relocation, and maintenance of the equipment more convenient, further improving its operability and practicality.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 - Figure 5 As shown, an auxiliary welding device for use in the rear floor and side panel assembly is composed of several key components, including a platform 1, a mounting frame 2, a positioning clamp 3, and a support frame 4. These components work together to ensure the precision and efficiency of the welding process. The platform 1 serves as the foundation of the device, bearing the weight of the entire unit, while the support frame 4 is installed at the lower end of the platform 1, providing stable support and ensuring the stability of the device during the welding process. Multiple platforms 1 are arranged in an array; this design not only ensures the stability and expandability of the device but also allows it to adapt to welding operations of different sizes.

[0015] The positioning fixture 3 is fixed to the platform 1 via the mounting bracket 2. Its main function is to achieve precise positioning and clamping of the rear floor and side panel assembly. To further improve welding accuracy, two rows of support frames 4 are also arranged in an array, with notches 6 on their inner walls. Limiting pulleys 7 are installed inside the notches 6. These pulleys slide in limiting grooves 9 on the side walls of the moving track 8, thereby adjusting the position of the moving track 8 between the two rows of support frames 4. This design allows the moving track 8 to extend beyond the length of the platform 1 as needed, thus accommodating welding operations of different sizes.

[0016] A movable base 10 is connected to the upper end of the moving track 8, and a welding robot 11 is mounted on the upper end of the movable base 10. The welding robot 11 is connected to the welding gun 13 via a connector 12. The welding robot 11 can drive the welding gun 13 to perform precise welding operations at the positioning fixture 3, thereby ensuring the welding quality of the rear floor and side panel assembly. To further improve the flexibility and expandability of the equipment, two adjacent platforms 1 are connected by a hinge device. These hinge devices not only allow the platforms 1 to expand outward, but also allow the positions of the platforms 1 and the positioning fixture 3 to be changed. The outward expansion function of the platforms 1 allows the expansion cavity 14 to be enlarged, thereby providing sufficient storage space for the welding robot 11 and the movable base 10.

[0017] Lifting components 5 are provided on the side wall of the support frame 4, and these lifting components 5 are fixed to the support frame 4 by welding. The design of the lifting components 5 allows the support frame 4 and the platform 1 to be lifted, thereby facilitating the installation and movement of the equipment. The limiting pulley 7 is mounted on the support frame 4 via a pivot, and its edge is arc-shaped to match the arc-shaped limiting groove 9 on the side wall of the moving track 8. The two limiting grooves 9 are symmetrically distributed on both sides of the moving track 8, ensuring a stable connection and restraint between the moving track 8 and the support frame 4.

[0018] The upper end of the moving track 8 has a T-shaped groove, and the bottom of the T-shaped groove has a screw hole. The moving seat 10 is embedded in the T-shaped groove of the moving track 8 and is adapted to the T-shaped groove. The moving seat 10 and the moving track 8 are fixed by bolts to ensure the stability and accuracy of the welding robot 11. To ensure the stable placement of the moving track 8 and the support frame 4, both of them are provided with support feet at their lower ends. In addition, the lower end of the moving track 8 also has a forklift slot, through which a forklift can be inserted to realize the movement of the moving track 8, further improving the flexibility and ease of operation of the equipment.

[0019] Adjust the position of the positioning fixture 3 according to the dimensions of the rear floor and side panel assembly to ensure it can accurately clamp the parts to be welded. Confirm the positioning accuracy of the positioning fixture 3 and make fine adjustments if necessary. Adjust the position of the moving track 8 according to the welding operation requirements. The position adjustment is achieved by sliding the limiting pulley 7 on the moving track 8 in the limiting groove 9. Ensure that the moving track 8 stably extends the length of the platform 1 between the two rows of support frames 4.

[0020] Connect the welding robot 11 to the moving base 10, and connect the welding gun 13 via the connector 12. Adjust the position of the welding robot 11 to the precise welding position of the positioning fixture 3. Place the rear floor and side panel assembly on the positioning fixture 3, ensuring they are properly clamped. Start the welding robot 11 to perform precise welding operations. Monitor the welding process to ensure the welding quality meets standards.

[0021] After welding is completed, clean the welding area to ensure there are no residues on the equipment. Perform routine maintenance on the equipment, checking that all components are in good condition to ensure the equipment's performance for the next use.

[0022] If the equipment needs to be expanded to accommodate larger welding operations, extend the adjacent platform 1 outwards using the hinge device. Adjust the position of the positioning clamp 3 to ensure it matches the expanded platform 1. If further stabilization is required, hoist the support frame 4 and platform 1 using the lifting device 5. Confirm that the support frame 4 has the lifting device 5 on its side wall and secure it by welding. Ensure that the limiting pulley 7 is mounted on the support frame 4 via a pivot and matches the arc-shaped limiting groove 9 on the side wall of the moving track 8. Adjust the two limiting grooves 9 to ensure they are symmetrically distributed on both sides of the moving track 8 for stable connection and restraint.

[0023] The movable base 10 is embedded into the T-shaped groove of the moving track 8, ensuring a proper fit. The movable base 10 and the moving track 8 are secured with bolts to ensure the stability and accuracy of the welding robot 11. The moving track 8 is moved by inserting a forklift into the forklift slot at its lower end. Support feet are provided at the lower ends of both the moving track 8 and the support frame 4 to provide stable placement. This auxiliary welding equipment maintains accuracy and efficiency in welding operations of different sizes and types.
