[0001] This utility model relates to the field of automotive parts welding technology, specifically to an automotive parts welding device with clamping and positioning functions. Background Technology

[0002] Welding is a crucial process in the manufacturing of automotive parts, and its quality directly affects the structural safety and reliability of the entire vehicle. In particular, the welding of sheet metal automotive parts (such as door inner panels, trunk lids, chassis reinforcements, etc.) usually requires the precise welding of multiple stamped sheet metal parts at specific locations. Currently, the following technical difficulties and shortcomings are commonly found in welding operations in this field: Clamping damage and instability: Traditional clamps (such as bolts and cylinders) are prone to causing rigid damage to the surface of the workpiece, and have poor anti-slip properties. The workpiece is easy to shift during welding, which affects the positioning accuracy. Insufficient automation and precision: Manual operations have low precision and efficiency; fully automated welding robots are costly and lack flexibility, making it difficult to balance high precision and high efficiency. Low equipment reliability: The structural design of key moving parts is unreasonable, making them prone to wear and jamming, resulting in unstable operation and high maintenance costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please refer to the following: Figure 1-3 , A welding device for automotive parts with clamping and positioning functions, comprising: Supporting components include: Support plate 1 is used to support the plate-shaped automotive parts to be welded. The support plate 1 has a groove for placing the parts. The fixing frame 12 serves as a fixed support; The clamping assembly includes: Hydraulic rod 4 is disposed between movable plate 14 and support plate 1 to provide clamping driving force; A movable plate 14 connected to the output end of hydraulic rod 4; The sliding rod 2, which is slidably disposed between the support plates 1, is connected at its upper end to the movable plate 14 and moves synchronously with the movable plate 14. A horizontal plate 3 is fixedly connected to the lower end of the slide bar 2; The sliding plate 15 is slidably set on the horizontal plate 3; The upper end of the guide rod 9 is connected to the sliding plate 15, and the lower end of the guide rod 9 is connected to the pressure plate 11 for directly pressing the fittings. The spring 10, which cooperates with the guide rod 9 and the pressure plate 11, is used to apply a buffering force to achieve pre-compression; Welding components, including: L-shaped plate 5 is slidably connected between the support plates 1; A hydraulic rod 13 is installed between the fixed frame 12 and the L-shaped plate 5, and its output end is connected to the L-shaped plate 5 to drive the L-shaped plate 5 to rise and fall. Welding structure 7 for performing welding operations; Motor 8 is fixedly mounted on L-shaped plate 5; The threaded rod 6 is connected to the output shaft of the motor 8. The welded structure 7 is threadedly engaged with the threaded rod 6 and slidably mounted on the L-shaped plate 5, and slides as the threaded rod 6 rotates. Specifically, in the support assembly, the support plate 1 supports the plate-shaped automotive parts to be welded through its groove, providing a stable placement reference for the parts; the fixing frame 12 serves as the basic support structure of the overall device, providing an installation and stress-bearing carrier for the welding assembly; The operating logic of the clamping assembly is as follows: After the hydraulic rod 4 is activated, it generates driving force, pushing the moving plate 14 downward. The moving plate 14 drives the slide rod 2 connected to it to slide downward along the support plate 1, which in turn drives the horizontal plate 3 at the lower end of the slide rod 2 to move downward simultaneously. The sliding plate 15 on the horizontal plate 3 moves downward accordingly, and through the guide rod 9, it drives the pressure plate 11 to approach the accessory. Finally, the pressure plate 11 directly clamps the accessory. During this process, the spring 10 cooperates with the guide rod 9 and the pressure plate 11 to apply buffer force through elastic deformation, so as to avoid excessive pressure and damage to the accessory, thereby achieving pre-clamping and fixing of the accessory. The operating logic of the welding assembly is as follows: After the hydraulic rod 13 is started, it drives the L-shaped plate to slide down along the support plate 1, so that the welding structure 7 is close to the welding gap of the accessory and fits in place; then the motor 8 is started, driving the threaded rod 6 to rotate. Since the welding structure 7 is threadedly engaged with the threaded rod 6 and is slidably set on the L-shaped plate, the rotation of the threaded rod 6 is converted into the straight sliding of the welding structure 7 along the L-shaped plate, thereby completing the welding operation of the accessory gap. In the embodiment: the spring 10 is sleeved on the outside of the guide rod 9, one end of which abuts against the sliding plate 15 and the other end abuts against the pressure plate 11, providing a buffer preload force through elastic deformation; Specifically, the spring 10 is sleeved on the outside of the guide rod 9, with one end in contact with the sliding plate 15 and the other end in contact with the pressure plate 11. When the clamping assembly is in operation, the sliding plate 15 moves down and pushes the pressure plate 11 through the guide rod 9. The spring 10 is compressed and produces elastic deformation. Its force to recover deformation will act on the pressure plate 11, which not only enhances the clamping force of the pressure plate 11 on the accessories, but also avoids damage to the accessories caused by rigid contact through elastic buffering, ensuring a more stable pre-clamping effect. In the embodiment: the slide rod 2 is a cylindrical structure, and the support plate 1 has a through hole that is adapted to the slide rod 2. The slide rod 2 and the through hole are fitted together to achieve sliding. Specifically, the slide bar 2 is designed as a cylinder, and the through hole on the support plate 1 is adapted to the size of the slide bar 2, and the two are fitted with a clearance fit; this structure ensures that the slide bar 2 can slide smoothly along the through hole under the drive of the moving plate 14, reducing frictional resistance, ensuring the stability and accuracy of the downward movement of the horizontal plate 3 and the subsequent pressure plate 11, and avoiding the impact of sliding jamming on the pressing effect; In the embodiment: the L-shaped plate 5 is provided with a protrusion on the side near the support plate 1, and the support plate 1 is provided with a strip groove that matches the protrusion. The L-shaped plate 5 achieves sliding connection through the cooperation of the protrusion and the strip groove. Specifically, a protrusion is provided on the side of the L-shaped plate near the support plate 1, and a corresponding strip groove is opened on the support plate 1, with the protrusion embedded in the groove; when the hydraulic rod 13 drives the L-shaped plate to rise and fall, the protrusion slides along the strip groove to provide guidance for the L-shaped plate, ensuring that its rising and falling trajectory is stable, so that the welding structure 7 can be accurately aligned with the welding gap of the accessory, avoiding deviation that affects the welding accuracy; In the embodiment: the lower surface of the pressure plate 11 is provided with a rubber anti-slip pad, and the surface of the rubber anti-slip pad is provided with a diamond-shaped anti-slip pattern; Specifically, the rubber anti-slip pad on the lower surface of the pressure plate 11 is elastic, which can increase the fit with the surface of the accessory; the diamond-shaped anti-slip pattern on the surface can increase the friction, effectively prevent the accessory from sliding during the pressing or welding process, and further improve the stability of clamping and positioning. In the embodiment: hydraulic rod 1 4, hydraulic rod 2 13 and motor 8 are existing structures, and the control circuit can be implemented by those skilled in the art through simple programming. They are common knowledge in the art. They are used without modification, so the control method and circuit connection will not be described in detail. Working principle: When using this device, two plate-shaped automotive parts to be welded are placed on the support plate 1. Then, the hydraulic rod 4 is controlled to move the moving plate 14 downward. The moving plate 14 will move the sliding rod 2 downward, which will move the horizontal plate 3 downward. The horizontal plate 3 will move the sliding plate 15 sliding on it downward, which will move the guide rod 9 and the pressure plate 11 downward, thus achieving the effect of pressing the parts. The spring 10 applies a buffering force to achieve the effect of pressing and fixing the parts. When welding is required, the hydraulic rod 13 is controlled to move the L-shaped plate 5 downward, which will move the welding structure 7 downward and fit it against the weld seam. Then, the motor 8 is turned on. The motor 8 drives the threaded rod 6 to rotate, which will cause the welding structure 7 to slide on the L-shaped plate 5, thus achieving the effect of welding the automotive parts.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
