Technical Field

[0001] This utility model relates to the field of welding positioning fixture technology, and in particular to welding positioning and flipping fixtures for roofs of special vehicles. Background Technology

[0002] The roof cover is an essential protective structure for the top of a vehicle, and it is especially crucial for protective vehicles used in cash transport, armed escort, and special forces operations. In the product design of protective vehicles, the accuracy of the roof cover's welded dimensions is an important indicator, as it improves the overall consistency of the vehicle's appearance.

[0024] like Figures 1 to 3 As shown, this utility model provides a welding positioning and flipping fixture for a special vehicle roof, including a platform support frame 1, a platform skeleton 2, a clamping skeleton 3, and a positioning pin 4. The platform skeleton 2 has a rotating shaft 21, which is rotatably connected to the platform support frame 1. The platform skeleton 2 has a first positioning hole, and a limiting member 22 is provided at the end of the platform skeleton 2. The clamping skeleton 3 is detachably connected to the platform skeleton 2. The platform skeleton 2 and the clamping skeleton 3 are used to clamp and fix the vehicle roof. The platform support frame 1 has multiple second positioning holes 11 along the circumference of the rotating shaft 21. The positioning pin 4 is used to pass through the first positioning hole and the second positioning hole 11 to fix the tilt angle of the platform skeleton 2. Specifically, through the cooperation of the platform skeleton, the clamping skeleton, and the positioning pin, the roof can be quickly clamped, flipped at multiple angles, and precisely positioned, which significantly improves the welding accuracy and operating efficiency.

[0025] In one embodiment, the platform support frame 1 includes side supports 12 and connecting rods 13. The two side supports 12 are spaced apart, and one end of the connecting rod 13 is fixedly connected to one of the side supports 12, while the other end of the connecting rod 13 is fixedly connected to the other side support 12. Specifically, the platform support frame adopts a side support and connecting rod structure, which enhances the overall rigidity and stability and prevents deformation or shaking during the welding process.

[0026] In one embodiment, the platform support frame 1 further includes a base plate 14, which is fixedly connected to the bottom of the side support 12 and is used to fix it to the ground. Specifically, the base plate design allows the tooling to be firmly fixed to the ground, further ensuring the safety and stability of the welding process.

[0027] In one embodiment, the platform support frame 1 is provided with a shaft hole, and the rotating shaft 21 is detachably connected to the shaft hole. Specifically, the detachable connection between the rotating shaft and the shaft hole facilitates later maintenance and component replacement. Simultaneously, the platform frame 2 can be replaced with one that is adapted to the size and shape of the vehicle's roof.

[0028] In one embodiment, the system further includes a shaft fixing plate 5 and a first screw 6. The shaft fixing plate 5 abuts against the end face of the rotating shaft 21, and the first screw 6 is threadedly connected to the shaft fixing plate 5 and the platform support frame 1. Specifically, the combination of the shaft fixing plate and the first screw achieves reliable axial positioning of the rotating shaft, preventing the rotating shaft from falling off during the flipping process.

[0029] In one embodiment, a spring washer 7 and a flat washer 8 are also included. The spring washer 7 is disposed between the shaft fixing plate 5 and the platform support frame 1, and the flat washer 8 is disposed between the nut of the first screw 6 and the shaft fixing plate 5. Specifically, the cooperation of the spring washer 7 and the flat washer 8 effectively prevents the first screw 6 from loosening due to vibration, ensuring long-term reliability.

[0030] In one embodiment, a second screw 9 is also included, which is threadedly connected to the clamping frame 3 and the platform frame 2. Specifically, the second screw 9 connects the clamping frame 3 and the platform frame 2, providing an adjustable clamping force that can adapt to the clamping requirements of parts of different thicknesses, making it highly versatile.

[0031] In one embodiment, a shim 10 is also included, which is disposed between the platform frame 2 and the platform support frame 1. Specifically, the shim 10 can temporarily fix the platform frame 2 before the positioning pin 4 is installed. After the platform frame 2 is temporarily fixed to the platform support frame 1, it is convenient to further install the positioning pin 4 to fix the platform frame 2 and the platform support frame 1.

[0032] In one embodiment, a straight-through grease cup 20 is also included. The straight-through grease cup 20 is threadedly connected to the platform frame 2, and the oil outlet of the straight-through grease cup 20 is connected to the gap between the rotating shaft 21 and the platform support frame 1. Specifically, the straight-through grease cup 20 facilitates the periodic addition of lubricating grease, ensuring flexible rotation of the rotating shaft and extending the service life of the tooling.

[0033] In one embodiment, there are multiple clamping frames 3, which are spaced apart and detachably connected to the platform frame 2. Specifically, the spaced arrangement of multiple clamping frames allows for flexible adjustment of the clamping points according to the size and structure of the roof, improving the adaptability and versatility of the tooling.

[0034] The usage process of this embodiment is as follows: First, the tooling is stably placed at the welding station using the foot plate 14, and the foot plate 14 is fixed to the ground with bolts to ensure that the tooling does not wobble during use. After assembly, an appropriate amount of grease is added by screwing on the straight-through grease cup 20, allowing the grease to fully lubricate the contact surface between the grease and the platform support frame 1 through the oil guide groove on the rotating shaft 21. The roof panel to be welded is placed on the platform frame 2, with its end close to the limiting member 22, to ensure that the initial placement position of all workpieces is consistent and to control the welding dimensions. The clamping frame 3 is placed over the roof panel. Depending on the length of the workpiece, multiple clamping frames 3 can be installed to evenly distribute the clamping force. The second screw 9 is passed through the mounting hole on the clamping frame 3 and screwed into the corresponding threaded hole on the platform frame 2. By tightening the second screw 9, the downward pressure generated by the thread causes the clamping frame 3 and the platform frame 2 to clamp the roof panel together, achieving reliable fixation. At this point, the platform frame 2 is in a horizontal position (0°). The positioning pin 4 is inserted into the first positioning hole and the corresponding second positioning hole 11 to lock the angle. Workers can then begin welding the upper surface of the roof. After welding the upper surface, the positioning pin 4 is removed. Using the rotating shaft 21 as the axis, the platform frame 2 is manually or with the aid of auxiliary tools rotated upwards to the desired angle (e.g., 90°, 135°, or 180°). When the first positioning hole on the platform frame 2 aligns with another second positioning hole 11 on the platform support frame 1, the positioning pin 4 is inserted to lock the angle, allowing for welding of the sides or bottom. Repeating the above steps allows the platform frame 2 to be flipped back to its initial position or other working angles. This process is simple and quick, greatly reducing the labor intensity of workers.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
