By setting a fixed block, a connecting block, a fixed rod, a connecting rod, a rotating rod, a connecting hole, a rotating block and a limit bolt, it is convenient to weld various parts of the automobile door panel.

[0004] However, the angle at which the door panel is fixed by the above-mentioned device cannot be adjusted, and the car door panel can only be processed in the horizontal direction. When the door panel needs to be processed at an angle inclined relative to the door panel, the worker needs to bend the body to a certain angle. Maintaining the body bent at a certain angle for a long time can easily cause muscle damage, and it also consumes a lot of physical energy for the workers. Therefore, there is a need for a device that can adjust the fixing angle of the car door panel so that the car door panel can be firmly fixed at different angles for easy processing.

DETAILED DESCRIPTION

[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Example

[0025] Figure 1-Figure 4 This is an embodiment of the utility model, a clamp for positioning, assembling and processing automobile door panels, including a support frame 1, the top of the support frame 1 is an inclined surface, the top of the support frame 1 is fixedly connected to an outer frame 2, and a clamping assembly 3 is rotatably connected between the two sides of the outer frame 2. The automobile door panel is placed on the clamping assembly 3 and fixed, and then the clamping assembly 3 and the door panel above it are rotated to a suitable angle along the outer frame 2. The staff processes the inclined automobile door panel and can conveniently adjust the fixing angle of the automobile door panel, so that the automobile door panel can be firmly fixed at different angles for convenient processing.

[0026] The clamping assembly 3 includes a rotating frame 31 rotatably connected to the outer frame 2, a supporting plate 32 is installed on the outside of the rotating frame 31, a tilting frame 33 is fixedly connected to the top of the supporting plate 32, a plurality of first clamps 34 are fixedly connected to one side of the tilting frame 33, a second clamp 35 is fixedly connected to the top of the outer frame 2, a clamping head of the first clamp 34 extends downwardly from the outer frame 2, and a clamping head of the second clamp 35 extends upwardly from the outer frame 2. Initially, one end of the top of the rotating frame 31 abuts against the outer frame 2, and the car door panel is placed on the first clamp 34 and the second clamp 35. One side of the car door panel is wrapped by the clamping head of the first clamp 34, and the other side is wrapped by the clamping head of the second clamp 35. At this time, the rotating frame 31 and the car door panel above it are at the minimum tilt angle. When the tilt of the car door panel needs to be adjusted When adjusting the angle, the staff rotates the rotating frame 31, thereby driving the car door panel on the rotating frame 31 to rotate to a suitable angle, and then maintains the inclination angle of the rotating frame 31 and the car door panel, and the staff processes the rotated car door panel to facilitate the processing of the car door panel after adjusting the angle. Since the first clamp 34 and the second clamp 35 have different directions, the clamping head of the first clamp 34 squeezes the car door panel upward when squeezing the car door panel, and the clamping head of the second clamp 35 squeezes the car door panel downward when squeezing the car door panel, so that the car door panel can always be squeezed from different directions and multiple positions simultaneously during the process of adjusting the inclination angle of the car door panel, preventing the car door panel from shaking to one side due to the clamp itself, thereby improving the firmness of the car door panel when adjusting the angle.

[0027] One end of the rotating frame 31 is fixedly connected to the bending frame 4, and the outer sleeve of the bending frame 4 is provided with a rubber sleeve 5. When it is necessary to adjust the angle of the rotating frame 31 and the car door panel above it, the staff holds the rubber sleeve 5 on the bending frame 4 and pushes the bending frame 4 upward, thereby rotating the rotating frame 31 and the car door panel above it counterclockwise until the car door panel is rotated to a suitable processing angle, and then fixes the angle of the rotating frame 31 to facilitate the rotation of the rotating frame 31 and the car door panel.

[0028] The top of the outer frame 2 is provided with a slide groove, and a push plate 6 is slidably connected between the two sides of the inner wall of the slide groove. One end of the rotating frame 31 is supported by the push plate 6 from the bottom. The bottom of the outer frame 2 is provided with a threaded rod 7 with one end movably passing through the outer frame 2. The threaded rod 7 is rotatably connected to the bottom of the push plate 6, and a protrusion 8 is fixedly connected to the bottom of the threaded rod 7. When the rotating frame 31 and the automobile door panel above it are rotated to a suitable angle, the staff rotates the protrusion 8, thereby driving the threaded rod 7 to rotate, and then pushing the push plate 6 to rise until the push plate 6 is close to the bottom of the rotating frame 31. At this time, the bottom of the rotating frame 31 is supported by the push plate 6, and the staff stops rotating the protrusion 8. After the rotating frame 31 and the automobile door panel above it are rotated to a suitable angle, they can be conveniently fixed. There is no need for the staff to always support the rotating frame 31, which reduces the possibility of shaking of the automobile door panel during processing after adjusting the angle.

[0029] The top of the tilting frame 33 is fixedly connected to the side frame 9, and the controller of the first clamp 34 is installed in the side frame 9. The top of the tilting frame 33 is fixedly connected to the bottom plate 10, and the top of the bottom plate 10 is fixedly connected to the winding drum 11. The pipeline of the first clamp 34 is wound on the winding drum 11. The first clamp 34 and the second clamp 35 are both pneumatically controlled to control the clamping degree. Since the second clamp 35 is fixed on the outer frame 2 and does not move, the pipeline and controller of the second clamp 35 only need to be installed on the support frame 1, and the first clamp 34 moves with the rotating frame 31, causing the pipeline of the first clamp 34 to move with the movement of the rotating frame 31. In order to reduce the possibility of the pipeline of the first clamp 34 being entangled and pulled and broken, and to improve the stability of the controller of the first clamp 34 that controls the air supply of the ventilation pipeline, the controller of the first clamp 34 is installed in the side frame 9, and the pipeline is wound on the winding drum 11, so as to reduce the movement of the controller and the pipeline relative to the first clamp 34.

[0030] The top of the support plate 32 is fixedly connected to the square tube 12, and the inclined frame 33 is installed on the top of the square tube 12. A plurality of through holes are provided on the outer side of the square tube 12. During the processing of the automobile door panel, the welding process of the automobile door panel is involved. A lot of heat is generated during welding. The heat is transferred to the automobile door panel and then transferred to the square tube 12 through the first clamp 34. The square tube 12 and the through holes above it increase the heat dissipation area and accelerate the cooling speed of the automobile door panel during welding.
