Specific embodiments

[0027] The following combines the accompanying drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0028] "Top surface", "bottom", and "bottom surface" are referenced based on the normal use state of the fully automatic welding equipment, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model.

[0029] As Figures 1-3 shown, a fully automatic welding equipment for an integrated vehicle frame includes an operating table 1, the top surface of the operating table 1 having at least two working positions; a tooling fixture 2 for clamping and fixing the vehicle frame; a moving mechanism disposed on the working positions of the operating table 1, the moving end of the moving mechanism being fixedly connected to the tooling fixture 2, the moving mechanism being configured to control the lifting and tipping of the tooling fixture 2; a storage groove 103 disposed on the working positions of the operating table 1, the storage groove 103 being configured to accommodate the moving mechanism; and a welding mechanism disposed on the operating table 1 for welding the vehicle frame.

[0030] The above-mentioned welding equipment can be used for welding the frame of an electric vehicle. When in use, the various components of the frame are assembled into a complete frame on the tooling fixture 2, and the frame is fixed by the tooling fixture 2. Then, the frame is welded by the welding mechanism; there are two tooling fixtures 2 arranged on the operation table 1. When one tooling fixture 2 is in the welding state, the other tooling fixture 2 can be used for taking and placing the frame. In this way, the welding equipment does not need to stop and wait, and can realize continuous welding operations, improving the welding efficiency of the welding equipment; the tooling fixture 2 is connected to the operation table 1 through the moving mechanism, and the lifting and flipping of the tooling fixture 2 can be controlled through the moving mechanism, so as to adjust the angle of the tooling fixture 2, enabling the welding equipment to weld the frame from multiple angles, reducing the probability of the welding parts of the frame being blocked, improving the integrity of the automatic welding of the frame by the welding equipment, reducing the number of manual repair welds, and further improving the production efficiency of the welding equipment; the setting of the storage groove 103 can be used to store the moving mechanism. After the moving mechanism is stored inside the storage groove 103, the tooling fixture 2 can be placed on the top surface of the operation table 1, so that the disassembly and assembly between the tooling fixture 2 and the moving mechanism can be realized without the assistance of a hoisting mechanism, thereby improving the convenience of replacing the tooling fixture 2 and facilitating the welding equipment to weld frames of different models.

[0031] A further improvement is that, as Figure 3 and 4 shown, the moving mechanism includes a lifting hydraulic cylinder 501 vertically arranged at the bottom of the storage groove 103 and two flipping hydraulic cylinders 502. The lifting end of the lifting hydraulic cylinder 501 is rotatably connected with a movable plate 4 that can enter the inside of the storage groove 103. The rotation axis line of the movable plate 4 is horizontally distributed. The two flipping hydraulic cylinders 502 are respectively arranged on both sides of the rotation axis line of the movable plate 4, and the connection line between the two flipping hydraulic cylinders 502 is perpendicular to the rotation axis line of the movable plate 4; the lifting end of the lifting hydraulic cylinder 501 is horizontally and fixedly connected with a fixed shaft 504, and a rotating sleeve 401 is coaxially sleeved on the fixed shaft 504. The rotating sleeve 401 is fixedly connected with the bottom surface of the movable plate 4.

[0032] In the above-mentioned welding equipment, two lifting hydraulic cylinders 501 can be provided. The fixed shaft 504 is horizontally mounted between the lifting ends of the two lifting hydraulic cylinders 501, so that the lifting of the lifting hydraulic cylinders 501 can control the lifting of the movable plate 4. While the lifting hydraulic cylinders 501 are lifting, the tilting hydraulic cylinders 502 lift synchronously, and their movable ends always abut against the bottom of the movable plate 4, thereby realizing multi-point support for the movable plate 4 and improving the stability of the movable plate 4. During tilting, one tilting hydraulic cylinder 502 extends and the other tilting hydraulic cylinder 502 retracts, then the movable plate 4 can be rotated around the fixed shaft 504 to realize the tilting of the movable plate 4. By driving the vehicle frame to lift and tilt synchronously through the movable plate 4, the angle adjustment of the vehicle frame is realized, so that the welding mechanism can weld the vehicle frame from different angles, improving the integrity of the welding of the vehicle frame by the welding mechanism and the production efficiency of the welding equipment.

[0033] A further improvement is that, as Figure 4 shown, rollers 503 are provided at the lifting ends of the tilting hydraulic cylinders 502, and the rollers 503 are in rolling connection with the bottom surface of the movable plate 4. The setting of the rollers 503 can reduce the friction between the tilting hydraulic cylinders 502 and the bottom surface of the movable plate 4, thereby reducing the mutual wear between the two and reducing the loss and failure rate of the welding equipment.

[0034] A further improvement is that, as Figure 1 shown, the tooling fixture 2 has a mounting seat 201 detachably connected to the movable plate 4, and the mounting seat 201 can completely cover the top opening of the storage groove 103. A plurality of mounting holes 402 corresponding to each other in position are provided on both the mounting seat 201 and the movable plate 4, so that the mounting seat 201 and the movable plate 4 can be fixed by bolts and nuts, and the disassembly and assembly between the two are convenient, improving the convenience of replacing the tooling fixture 2; the coverage range of the top opening of the storage groove 103 is smaller than the coverage range of the mounting seat 201, so that the mounting seat 201 can be mounted on the opening of the storage groove 103, and the movable plate 4 can be received inside the storage groove 103. Under the supporting action of the operating table 1 on the mounting seat 201, the stability of the mounting seat 201 placed after being separated from the movable plate 4 is improved, and when the two are installed, it is convenient to move the mounting seat 201 to dock with the mounting holes 402 on the movable plate 4, thereby improving the convenience of disassembling and assembling the tooling fixture 2.

[0035] A further improvement is that, as Figures 1-3 shown, a plurality of balls 102 are evenly distributed on the top surface of the operating table 1. The setting of the balls 102 can reduce the friction between the operating table 1 and the mounting seat 201, thereby facilitating the movement of the tooling fixture 2 on the operating table 1. After the tooling fixture 2 is separated from the movable plate 4, it is convenient to replace the tooling fixture 2. When the tooling fixture 2 is connected and fixed to the movable plate 4, it is convenient to move the tooling fixture 2 to align with the movable plate 4, thereby improving the convenience of replacing the tooling fixture 2.

[0036] A further improvement is that, as Figures 1-3 shown, one side of the operating table 1 has a slope 101, and a plurality of balls 102 are evenly distributed on the surface of the slope 101. The setting of the slope 101 facilitates the picking and placing of the tooling fixture 2 on the operating table 1 without auxiliary tools, further improving the convenience of disassembly, installation and replacement of the tooling fixture 2; the setting of the balls 102 can improve the smoothness of the movement of the tooling fixture 2, making the handling of the tooling fixture 2 more labor-saving.

[0037] A further improvement is that, as Figure 2 shown, the welding mechanism includes a track 104 fixedly connected to the operating table 1, a moving trolley 303 is slidably connected to the track 104, a robotic arm 301 is installed on the moving trolley 303, and a welding head 302 is arranged at the movable end of the robotic arm 301. The moving trolley 303 can drive the welding head 302 to move along the track 104, and the setting of the robotic arm 301 can realize the adjustment of the position and angle of the welding head 302, so that the welding head can weld the vehicle frame from different positions and angles, improving the convenience of welding.
