Description

Technical Field

[0001] This utility model relates to the field of automotive door ring processing technology, specifically to an integrated door ring gripper projection welding device for new energy vehicles. Background Technology

[0002] In the field of new energy vehicle body manufacturing, the integrated door ring is a key structural component, and its manufacturing precision directly affects the safety, assembly quality, and airtightness of the entire vehicle. Projection welding is the mainstream process for welding nuts, reinforcing plates, and other accessories in the door ring assembly. The precision and stability of this process are highly dependent on the performance of the welding fixture. Due to the extremely high requirements for positioning stability in welding operations, existing technologies for welding and fixing integrated door rings mostly adopt a single fixing method, fixing the door ring only from one side or in one direction. This is difficult to meet the high precision and stability requirements and can easily lead to lateral displacement or longitudinal movement of the door ring during the welding process. This can cause misalignment between the projection welding gripper and the part to be welded, which not only affects the strength of the weld joint but also increases the risk of errors in subsequent vehicle body assembly. Therefore, this utility model proposes a projection welding device for the integrated door ring gripper of new energy vehicles to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an integrated door ring gripper projection welding device for new energy vehicles, which improves the welding positioning stability of the door ring by coordinating the fixation of the side and top, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated door ring gripper projection welding device for new energy vehicles, including a workbench, on which multiple fixing blocks are fixedly installed, and each of the multiple fixing blocks is provided with a moving component; The movable component is connected to a movable tray for placing the door ring, and the movable tray is provided with a fixing component for limiting and fixing the integrated door ring. The movable component is used to drive the movable tray to move, thereby adjusting the position of the fixed component relative to the door ring.

[0005] Preferably, the moving component includes a first electric telescopic rod fixed to a fixed block, and a first connecting plate is fixedly connected to the output end of the first electric telescopic rod.

[0006] Preferably, two slide rods are fixedly connected to the first connecting plate, and the slide rods slide through the fixed block and are fixedly connected to the movable support plate.

[0007] Preferably, the fixing block has a sliding hole adapted to the slide rod, and the slide rod slides through the fixing block through the sliding hole.

[0008] Preferably, the fixing component includes a vertical plate fixedly installed on the movable pallet, a fixing plate fixedly installed on the vertical plate, and a second electric telescopic rod fixedly installed on the fixing plate.

[0009] Preferably, the output end of the second electric telescopic rod is fixedly connected to a second connecting plate, and two guide rods are fixedly connected to the second connecting plate. The lower end of the guide rod slides through the fixed plate and is connected to a movable plate.

[0010] Preferably, an anti-slip pad is fixed on the movable plate.

[0011] Preferably, the anti-slip mat is a high-temperature resistant rubber mat, and its surface is provided with anti-slip patterns.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a movable component and a fixed component, the vertical plate of the fixed component can limit the side of the door ring, while the movable plate and its anti-slip pad can work together to secure the top, forming a coordinated side and top fixing structure. This replaces the existing single fixing method, effectively improving the welding positioning stability of the door ring, avoiding lateral offset or longitudinal movement during welding, and ensuring welding accuracy.

[0018] 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.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: an integrated door ring gripper projection welding device for new energy vehicles, including a workbench 1. Multiple fixing blocks 2 are uniformly fixedly installed on the top surface of the workbench 1 along the door ring fitting contour. Each fixing block 2 is correspondingly configured with a moving component 3, and each set of moving components 3 is connected to a moving support plate 4 for supporting the door ring. The top surface of the moving support plate 4 is provided with a fixing component 5 for fixing the door ring. By driving the position adjustment of the moving support plate 4 through the moving component 3, the fixing component 5 can accurately correspond to the part of the door ring to be fixed, forming a multi-directional collaborative fixing structure.

[0021] like Figure 3 As shown, in the movable assembly 3, a first electric telescopic rod 31 is fixed to one side of the fixed block 2 by bolts. The output end of the first electric telescopic rod 31 is away from the movable pallet 4, and its output end is fixedly connected to the center of one side of the first connecting plate 33 by bolts. Two sliding rods 32 are symmetrically welded on the upper part of the first connecting plate 33. The axis of the sliding rod 32 is consistent with the extension direction of the first electric telescopic rod 31. At the same time, a sliding hole adapted to the outer diameter of the sliding rod 32 is opened on the fixed block 2. After the end of the sliding rod 32 away from the first connecting plate 33 slides through the sliding hole, it is fixedly connected to the bottom edge of the movable pallet 4 by welding or bolt connection.

[0022] like Figure 4As shown, in the fixed assembly 5, a vertical plate 51 is vertically welded to the top edge of the movable tray 4. The height of the vertical plate 51 is higher than the top height of the door ring after it is placed. A fixed plate 52 is horizontally welded to the top of the vertical plate 51 facing the center of the door ring. A second electric telescopic rod 55 is fixedly installed at the center of the top surface of the fixed plate 52 by bolts. The output end of the second electric telescopic rod 55 is vertically upward and welded to the center of the bottom surface of the second connecting plate 54. Two guide rods 53 are symmetrically welded to both ends of the bottom surface of the second connecting plate 54. The axis of the guide rod 53 is consistent with the extension direction of the second electric telescopic rod 55. A guide hole adapted to the guide rod 53 is opened on the fixed plate 52. The end of the guide rod 53 away from the second connecting plate 54 slides through the guide hole and is welded to the top edge of a horizontally set movable plate 56. An anti-slip pad 57 is bonded to the bottom surface of the movable plate 56 by high-temperature resistant adhesive. The anti-slip pad 57 is made of high-temperature resistant rubber material and its bottom surface is integrally formed with anti-slip patterns.

[0023] In this embodiment, the vertical plate 51 can directly abut against the side of the door ring to achieve lateral limiting of the door ring. The second electric telescopic rod 55 drives the moving plate 56 and the anti-slip pad 57 to rise and fall vertically, which can accurately press against the top surface of the door ring to form longitudinal compression. This forms a two-way fixing structure of "side limiting and top fixing", which effectively replaces the traditional single fixing method. At the same time, the high temperature resistance of the anti-slip pad 57 can adapt to the high temperature environment during the projection welding process, and the anti-slip pattern further enhances the friction with the surface of the door ring, preventing the door ring from moving longitudinally, improving the strength of the welded joint and the subsequent body assembly accuracy.

[0024] In use, the integrated door ring is placed on the movable support plate 4 to achieve initial bearing and positioning. Then, the first electric telescopic rod 31 in the movable component 3 is controlled to retract. The first connecting plate 33, which is fixedly connected to the output end of the first electric telescopic rod 31, will drive the two sliding rods 32 fixedly connected on it to slide, thereby driving the movable support plate 4 to move until the edge of the door ring abuts against the vertical plate 51. At this time, the edge of the door ring moves to the bottom of the movable plate 56 in the fixed component 5 set on the movable support plate 4. Next, the second electric telescopic rod 55 on the fixed plate 52 connected to the vertical plate 51 fixedly installed on the movable support plate 4 in the control fixed assembly 5 retracts. The second connecting plate 54 fixedly connected to the output end of the second electric telescopic rod 55 will drive the two guide rods 53 fixedly connected thereon to slide. The lower end of the guide rod 53 slides through the fixed plate 52 and connects with the movable plate 56, thereby driving the movable plate 56 and the anti-slip pad 57 fixed on the movable plate 56 to move, and finally realizes the limiting and fixing of the door ring.
