DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 4 As shown, the present invention provides a fixture for machining vehicle frame tubes, comprising a base 1, a riser 2 fixedly connected to its upper surface, and a rotating tube 3 rotatably mounted on the top of the riser 2. A drive assembly is mounted on the riser 2 to drive the rotating tube 3. The drive assembly comprises a first gear 12, a motor 13, and a second gear 19. The motor 13 is fixedly connected to the riser 2, the first gear 12 is fixedly connected to the drive shaft of the motor 13, and the second gear 19 is fixedly connected to the rotating tube 3. The first gear 12 and the second gear 19 are meshed and connected.

[0022] Specifically, the motor 13 rotates to drive the first gear 12 to rotate. Since the first gear 12 is meshed with the second gear 19 , the second gear 19 drives the rotating tube 3 to rotate.

[0023] A rotating drum 4 is fixedly connected to the end of the rotating tube 3 away from the riser 2. The rotating drum 4 surrounds the outer side of the rotating tube 3. A second square opening 6 is defined in the wall of the rotating tube 3, while a first square opening 5 is defined in the wall of the rotating drum 4. The first and second square openings 5 ​​are located in a corresponding manner. Multiple first and second square openings 5 ​​and 6 are provided. During use, the rotating drum 4 extends into the interior of the frame tube, allowing for positioning of the frame tube from the inside out.

[0024] A square sleeve 7 is fixedly connected between the first and second square openings 5, 6. A slide plate 18 is slidably connected to the interior of the sleeve 7. A sliding post 8 is slidably connected to the interior of the first square opening 5 and fixedly connected to the slide plate 18. When gas inside the rotating tube 3 is transported from the second square opening 6 to the interior of the square sleeve 7, the slide plate 18 pushes the sliding post 8 outward. An abutment plate 9 is fixedly connected to the end of the sliding post 8 located outside the rotating cylinder 4. To ensure that the abutment plate 9 matches the structure of the inner wall of the frame tube, the abutment plate 9 is curved, and the surface of the abutment plate 9 closest to the sliding post 8 is concave.

[0025] Specifically, when the gas inside the rotating tube 3 is transported to the inside of the square sleeve 7 through the second square port 6, the slide post 8 is pushed to slide outward through the slide plate 18, thereby causing the abutment plate 9 to be pressed against the inner wall of the frame tube, positioning the frame tube from the inside out, facilitating subsequent processing operations.

[0026] The provision of structures such as a drive assembly can drive the frame tube to rotate, making it easier to perform processing operations on the entire outer circumference of the frame tube.

[0027] Furthermore, a pressure sensor may be provided on the abutting plate 9 to monitor the squeezing force and prevent deformation of the frame tube.

[0028] A wind box 20 is fixedly connected to the riser 2, and a rotating tube 3 is rotatably connected to the wind box 20, communicating with the wind box 20. A pump body 14 is fixedly connected to the riser 2. The pump body 14 has two air outlets and two air inlets. One of the air outlets is connected to the factory's centralized air treatment pipeline, and the other is connected to the wind box 20 via a second air duct 17. One of the air inlets is connected to the atmosphere, and the other is connected to the first air duct 15. Each air outlet and air inlet is equipped with a solenoid valve.

[0029] In order to process the smoke and dust generated during welding and other processes, the first air duct 15 is connected to a hood 16 at one end away from the pump body 14. The hood 16 can be set according to the specific processing position to ensure the efficiency of smoke and dust extraction.

[0030] During operation, the solenoid valve on the air outlet end corresponding to the second air duct 17 and the solenoid valve on the air inlet end corresponding to the atmospheric environment are opened, and the pump body 14 transports the external air from the second air duct 17 and the air box 20 to the inside of the rotating tube 3. When the gas inside the rotating tube 3 is transported to the inside of the square sleeve 7 through the second square port 6, the slide column 8 is pushed to slide outward through the slide plate 18, thereby causing the abutment plate 9 to be pressed against the inner wall of the frame tube, positioning the frame tube from the inside to the outside, and then the solenoid valve on the air outlet end corresponding to the second air duct 17 is closed to keep the abutment plate 9 in a fixed position.

[0031] During processing, the solenoid valve on the outlet of the centralized air processing duct and the solenoid valve on the inlet of the first air duct 15 are opened. Pump body 14 extracts the smoke and dust generated during processing through the first air duct 15 and hood 16, thereby improving processing efficiency. The smoke and dust are then transported to the factory's centralized air processing duct.

[0032] Considering the reset of the sliding column 8 and the abutting plate 9, a support plate 10 is fixedly connected to the inner wall of the second square opening 6, and a spring 11 is fixedly connected to the support plate 10. The end of the spring 11 away from the support plate 10 is fixedly connected to the sliding column 8.

[0033] Specifically, the solenoid valve on the air outlet end corresponding to the second air duct 17 is opened, and the return elastic force of the spring 11 resets the sliding column 8 and the abutment plate 9, releasing the fixation of the frame tube, making it easier to remove the frame tube.
