Description

Technical Field

[0001] This utility model relates to the field of automotive tailgate welding, and in particular to a multi-angle clamping fixture for laser brazing of automotive tailgates. Background Technology

[0002] The tailgate, also known as the trunk lid, is the rear door of a vehicle, primarily used for storing items. The design and function of the tailgate vary depending on the vehicle model. In the event of a collision or other accident, the tailgate needs sufficient strength and rigidity to protect passenger safety. Furthermore, the tailgate must be equipped with safety devices such as locking mechanisms to prevent accidental opening while the vehicle is in motion.

[0003] Welding is required during the production and processing of automobile tailgates. Currently, laser brazing is generally used. Laser brazing is a brazing technology that uses a laser as a heat source to heat and melt the filler metal. It utilizes the principle of stimulated emission of atoms to stimulate the material to generate a laser beam with uniform wavelength, consistent direction, and very high intensity. This beam is focused into a high-power-density focal point, converting light energy into heat energy. In a very short time, a highly concentrated local heating area is formed at the joint, melting the filler metal and wetting it with the base material, finally completing the connection and forming of the workpiece.

[0004] When performing laser brazing on a car tailgate, a clamping fixture is required to hold and fix the tailgate. In the authorized Chinese utility model patent "Announcement No.: CN210789790U, Title: A Clamp for Welding the Inner Panel of a Car Tailgate", a clamping cylinder, a support plate, a fixed plate, a movable plate, a fixed clamping column, and a movable clamping column are set on the base plate. The clamping cylinder drives the movable plate to flip, so that the movable clamping column and the fixed clamping column clamp the workpiece and keep the workpiece stable. However, the position of the clamping frame in the above application is fixed, and it is difficult to change the clamping position according to the model of the car tailgate. This results in a small range of applicability of the clamping fixture and affects its practicality. Utility Model Content

[0049] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0050] Figures 1 to 5 The diagram shown is a structural schematic of an embodiment of the multi-angle clamping fixture for laser brazing of automotive tailgates according to this utility model. The multi-angle clamping fixture for laser brazing of automotive tailgates includes two fixed side plates 1.

[0051] Rotating component 2, with rotating component 2 connected to both of the two fixed side plates 1;

[0052] Fixed frame 3, multiple fixed frame 3 are provided between the two rotating components 2, and the two ends of the fixed frame 3 are respectively connected to the rotating component 2 through the moving component 4. The moving component 4 can adjust the position of the fixed frame 3;

[0053] Clamping assembly 5: Multiple clamping assemblies 5 are slidably connected to the fixing frame 3. The clamping assembly 5 is used to clamp and fix the tailgate of the car.

[0054] In this technical solution, the rotating component 2 can rotate the clamping component 5, the moving component 4 can move the longitudinal position of the clamping component 5, and the fixed frame 3 can move the lateral position of the individual clamping component 5 at will. This allows the clamping component 5 to be moved flexibly, thereby enabling the clamping component 5 to clamp and fix different models of car tailgates, expanding the applicability of the clamping fixture, and increasing the flexibility and practicality of the clamping fixture.

[0055] The clamping assembly 5 includes a sliding sleeve 51, which is slidably sleeved on the surface of the fixed frame 3.

[0056] The sliding sleeve 51 is provided with a power plate 52 on both the upper and lower sides. A threaded adjusting column 53 is threadedly connected to the power plate 52. A clamping plate 54 is rotatably connected to the lower end of the threaded adjusting column 53.

[0057] Each of the two power plates 52 is connected to a telescopic device 55 on one side opposite to the other, and the two telescopic devices 55 are respectively connected to the upper and lower sides of the mounting plate 56.

[0058] In this technical solution, multiple clamping components 5 can be used to clamp and fix the car tailgate from multiple angles.

[0059] The power plate 52 is connected to a follower column 57 on the side near the sliding sleeve 51, and the surface of the follower column 57 is slidably connected to one side of the sliding sleeve 51.

[0060] The side of the follower column 57 away from the power plate 52 is connected to an anti-slip rubber plate 58.

[0061] In this technical solution, the follower column 57 and the anti-slip rubber plate 58 are used to clamp the fixed frame 3 when clamping the tailgate of the car, thereby locking the position of the clamping component 5 relative to the fixed frame 3.

[0062] The sliding sleeve 51 is connected to a moving track 59 on its inner side, and the moving track 59 passes through the inner side of the fixed frame 3.

[0063] In this technical solution, the moving track 59 can be used to limit the moving trajectory of structures such as the sliding sleeve 51.

[0064] In use, depending on the position of the car tailgate, the sliding sleeve 51 can be slid along the fixed frame 3, so that the clamping plates 54 on both sides are on both sides of the car tailgate. Then, the telescopic device 55 drives the power plate 52 to move, which in turn drives the threaded adjustment column 53 and the clamping plate 54 to move, and the clamping plates 54 on both sides clamp and fix the car tailgate.

[0065] In use, the threaded adjusting column 53 can be rotated according to the thickness of the clamping part, so that the position of the clamping plate 54 can be adjusted to accommodate parts of different thicknesses.

[0066] When the power plate 52 moves, it can drive the follower column 57 to move in the same direction, which in turn can drive the anti-slip rubber plate 58 to move in the same direction. The anti-slip rubber plates 58 on both sides can clamp and fix the fixed frame 3, thereby locking the position of the sliding sleeve 51 and the clamping plate 54.

[0067] The rotating assembly 2 includes a rotating shaft 21, which is rotatably connected to the fixed side plate 1 through the shaft.

[0068] One end of the rotating shaft 21 is connected to the output end of the rotating power source 22, and the other end of the rotating shaft 21 is connected to the rotating plate 23;

[0069] The rotating power source 22 is connected to the inside of the mounting housing 24, and the mounting housing 24 is connected to one side of the fixed side plate 1.

[0070] In this technical solution, the angle of the clamping component 5 can be adjusted by using the rotating component 2.

[0071] In use, the rotary power source 22 can drive the rotary shaft 21 to rotate, which in turn drives the rotary plate 23 to rotate, which in turn drives the fixed frame 3 and the clamping assembly 5 to rotate, and the angle of the clamping assembly 5 can be changed.

[0072] The moving component 4 includes a moving threaded shaft 41, which is connected to the rotating plate 23. The rotating plate 23 has multiple moving slots arranged in a ring array. One end of the moving threaded shaft 41 is rotatably connected to the wall of the moving slot.

[0073] The movable threaded shaft 41 is threadedly connected to a movable plate 42. A connecting post 43 is connected to one side of the movable plate 42. The end of the connecting post 43 away from the movable plate 42 is connected to the side of the fixed frame 3.

[0074] In this technical solution, the lateral position of the fixed frame 3 and the clamping component 5 can be adjusted by using the movable component 4.

[0075] The inner wall of the movable groove is connected to a plurality of anti-deviation columns 44, and the surface of the anti-deviation columns 44 is slidably connected to the movable plate 42.

[0076] In this technical solution, the movement trajectory of the moving plate 42 can be limited by the anti-deviation column 44.

[0077] The rotating plate 23 has multiple mounting holes on its side, and one end of the movable threaded shaft 41 is rotatably connected to the side of the rotating plate 23 through the mounting holes.

[0078] The end of the movable threaded shaft 41 away from the rotating plate 23 is connected to a rotating knob 45.

[0079] In this technical solution, the threaded shaft 41 can be easily rotated and moved by rotating the knob 45.

[0080] In use, the knob 45 can be rotated as needed, which will drive the movable threaded shaft 41 to rotate. This will drive the movable plate 42 to move along the anti-deviation column 44, and then drive the connecting column 43 to move in the same direction. This will drive the fixed frame 3 and the clamping assembly 5 to move, and adjust the longitudinal position of the clamping assembly 5.

[0081] The cross-section of the power plate 52 is a Z-shaped structure.

[0082] The fixed frame 3 is connected to connecting posts 43 on both the left and right sides.

[0083] The rotary power source 22 is an electric motor or other device that can output rotational kinetic energy.

[0084] The telescopic device 55 is an electric push rod, a lifting cylinder, or other equipment with autonomous telescopic function.
