Description

Technical Field

[0001] The utility model relates to the technical field of automobile floor processing, and more specifically, the utility model relates to a forming tooling for welding nut plates of automobile floors. Background Technique

[0002] The nut plate is an important automobile part, and joints for assembling nuts are reserved on the surface of the nut plate. During the automobile production process, bolts and screws are used in combination to facilitate the fixed installation between other parts of the subsequent floor and the nut plate. Therefore, whether the welding position of the nut plate is accurate affects the positioning of other parts on the floor. After long-term use of the nut plate, the thread may become slippery. Therefore, the nut plate sometimes needs to be replaced during chassis maintenance.

[0003] In the prior art, during the welding and maintenance of the nut plate, it is necessary to operate the nut plate from below the automobile floor. The operating space below the automobile floor is small. The mechanical arm of a general welding tooling is long and occupies a large space, making it difficult to move and operate below the automobile floor, resulting in difficult movement and positioning during the welding of the nut plate.

[0004] The utility model patent with the patent application number CN202222965382.4 discloses a forming tooling for welding nut plates of automobile floors, including a first working plate and a second working plate. Among them, sliding grooves are opened on both outer side walls of the first working plate, and sliding plates are slidably connected to the inner side walls of the sliding grooves. A rotating plate is fixedly connected to the side surface of the sliding plate. The advantage of this structure is that it can facilitate the operator to weld the nut plate at the bottom of the automobile floor, achieving the effect of positioning and welding in the narrow space of the automobile chassis.

[0005] However, during actual use of this structure, during the process of welding the nut plate with a welding gun, strong light and high-temperature particles are likely to affect the operator. In view of this, the utility model proposes a forming tooling for welding nut plates of automobile floors. Content of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a forming tooling for welding nut plates of automobile floors to solve the problems raised in the above-mentioned background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A forming tooling for welding nut plates on an automotive floor, comprising a first working station plate and a second working station plate. A sliding groove is formed inside the first working station plate, and two movable blocks are slidably arranged on the inner wall of the sliding groove. One end of the movable block is provided with an extension block. On two outer walls of the first working station plate and corresponding to one side of the movable groove, rectangular openings for the extension block to extend out are formed, and the rectangular openings are communicated with the movable groove. The extension block is adapted to the structure of the rectangular opening. One end of the extension block is provided with a rotating plate, one end of the rotating plate is provided with a rotating shaft, and at the connection between the other end of the rotating plate and the extension block, a shaft pin is provided and is rotatably connected through the shaft pin. The rotating shaft is rotatably connected to the other end of the rotating plate. An adjusting column is arranged on the surface of the rotating shaft. One side of the adjusting column is provided with a connecting rod. A universal ball is jointly installed at the connection between the connecting rod and the adjusting column. Embedding grooves are formed at the relative ends of the connecting rod and the adjusting column, and the universal ball is embedded inside the embedding grooves. The connecting rod and the adjusting column are movably connected through the universal ball. One end of the connecting rod is provided with a welding gun.

[0008] It can be seen that in the above structure, the operator can lie on the unfolded first working station plate and second working station plate, extend the welding gun, and use the welding gun to weld the nut plate at the automotive floor, which is convenient for the operator to perform welding operations at the bottom of the automotive floor.

[0009] In order to enable the operator to be protected during welding and avoid the strong light and high-temperature particles generated during welding from affecting the operator, preferably, a protective structure is arranged on the outside of the connecting rod and on one side of the welding gun. The protective structure includes a goggles plate, which is fixedly installed on the outer wall of the connecting rod and on one side of the welding gun. A protective plate is arranged at the bottom of the goggles plate. Goggles are embedded on the surface of the goggles plate. A grip rod is arranged at the bottom end of the connecting rod, and an anti-slip rubber sleeve is arranged on the surface of the grip rod.

[0010] In order to enable the first working station plate and the second working station plate to be unfolded and folded, preferably, two first limiting rings are fixedly arranged on one side of the first working station plate. Both ends of the second working station plate are fixedly connected with second limiting rings. Connecting shafts are arranged at both ends of the second working station plate. A plurality of universal wheels are fixedly connected to the upper and lower surfaces of the first working station plate. The first working station plate is rotatably connected to the connecting shaft through the first limiting ring, and the second working station plate is rotatably connected to the connecting shaft through the second limiting ring.

[0011] For the convenience of using the welding gun and improving the flexibility during its use, preferably, a universal ball is jointly installed at the connection between the connecting rod and the adjusting column. Embedding grooves are provided at opposite ends of the connecting rod and the adjusting column, and the universal ball is embedded inside the embedding grooves. The connecting rod and the adjusting column are movably connected through the universal ball.

[0012] Technical effects and advantages of the present utility model:

[0013] By providing a protective structure, the goggles plate is installed outside the connecting rod, and a grip rod is provided at the bottom of the connecting rod. The operator holds the grip rod and drives the welding gun for welding operations. During the welding process, the operator's eyes operate through the goggles. The goggles can prevent strong light from causing discomfort to the operator's eyes. At the same time, high-temperature particles during the welding process can be blocked by the protective plate, thereby reducing the discomfort to the operator during the welding process.

[0014] By pulling the corresponding rotating plate outward, the movable block slides inside the sliding groove, and the extending block extends out from the rectangular opening. One end of the rotating plate is rotationally adjusted with the extending block through a pin, so that the position of the welding gun faces upward. At the same time, by rotating the other end of the rotating plate using the rotating shaft and performing universal adjustment through the universal ball between the connecting rod and the adjusting column, the position of the welding gun can be flexibly adjusted, and then the nut plate can be welded using the welding gun.

[0015] By folding and unfolding the first working position plate and the second working position plate using the cooperation of the first limiting ring, the second limiting ring, and the connecting shaft, and with the setting of the universal wheels, when the operator lies on the unfolded first working position plate and the second working position plate, the first working position plate and the second working position plate can be moved on the vehicle floor through the universal wheels, facilitating the welding operation for the operator.

The connecting rod 8 and the adjusting column 7 are movably connected through the universal ball 21. One end of the connecting rod 8 is provided with a welding gun 9.

[0025] In this structure, after the first working position plate 1 and the second working position plate 2 are unfolded, the operator can lie on the surfaces of the unfolded first working position plate 1 and the second working position plate 2. At the same time, according to the welding position of the nut plate on the vehicle floor, the corresponding rotating plate 5 is pulled outward, so that the movable block 3 slides inside the sliding groove, and the extension block 4 extends out from the rectangular opening 19. When the extension block 4 extends from the rectangular opening 19 to the outside, one end of the rotating plate 5 is rotationally adjusted with the extension block 4 through the pin 20, so that the position of the welding gun 9 faces upward;

[0026] The rotating shaft 6 is rotated at the other end of the rotating plate 5, and drives the welding gun 9 to adjust the position, and then the nut plate is welded by the welding gun 9.

[0027] In a specific embodiment, as shown in Figure 1 , 3 , Figure 5, a protective structure is arranged on the outside of the connecting rod 8 on one side of the welding gun 9.
