DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a tooling fixture for welding a condenser pipe of an automobile air conditioner, comprising a base 1, a pipe body is placed on the upper end of the base 1, and a vertical clamping part 2, the number of the vertical clamping parts 2 is two groups, and the vertical clamping parts 2 are connected to the outer surface of the upper end of the base 1, clamping the vertical part of the pipe body to increase the overall stability of the pipe body;

[0023] The bending clamping part 3 is arranged on the base 1 in the middle of the vertical clamping part 2 to clamp the bent part of the tube body.

[0024] The bending clamping portion 3 includes a connecting block 30, which is fixedly connected to the upper end of the base 1. A clamp 2 31 is provided at one end of the connecting block 30. The clamp 2 31 is designed as an L-shaped structure. A capsule 32 is fixedly connected to the outer surface of the upper end of the clamp 2 31. Electrorheological fluid is injected into the capsule 32. When in use, the user first turns off the power of the electrorheological fluid inside the capsule 32 to make it flow, and then prints the finished tube body on the surface of the capsule 32 to press the capsule 32 into a shape that matches the curved part of the tube body. Then, the electrorheological fluid is energized to solidify the shape. Through the above structure, tubes with different curved shapes can be fixed, avoiding the cumbersome steps of replacing the clamp and improving the use efficiency.

[0025] The outer surface of the second clamp 31 is fixedly connected with a guide rod 34, and the connecting block 30 and the guide rod 34 have guide grooves 35 at corresponding positions. The guide rod 34 is located inside the guide groove 35, and the outer surface of the guide rod 34 is marked with scales. The distance between the second clamp 31 and the connecting block 30 is adjusted along the guide groove 35 by the guide block, so that more shapes of tubes can be imprinted on the surface of the capsule 32.

[0026] A thread groove 39 is formed through the surface of the connecting block 30, and a threaded rod 40 is threadedly connected inside the thread groove 39. The end of the threaded rod 40 away from the connecting block 30 is rotatably connected to the second clamp 31. The distance between the second clamp 31 and the connecting block 30 can be adjusted by rotating the threaded rod 40, and the control can be more precise in combination with the scale.

[0027] The end of the threaded rod 40 away from the thread groove 39 is fixedly connected with a paddle 41, and the threaded rod 40 extends to the interior of the capsule 32. The electrorheological fluid is converted into liquid before adjustment. The threaded rod 40 is rotated, and the threaded rod 40 drives the paddle 41 to stir the electrorheological fluid inside the capsule 32. After the position of the clamp 31 is determined, the tube body is placed on the surface of the capsule 32 for imprinting. Finally, the electrorheological fluid is uniformly energized to turn it into a solid state. This not only shapes the capsule 32, but also positions the threaded rod 40, thereby increasing the stability of the structure.

[0028] A sliding groove 38 is provided at the upper end of the second clamp 31, and a sliding rod 36 is slidably connected inside the sliding groove 38. A lower pressure plate 33 is fixedly connected to the upper end of the sliding rod 36. A spring 37 is fixedly connected between the lower pressure plate 33 and the second clamp 31. The lower pressure plate 33 generates downward pressure on the tube body, which can achieve better imprinting in the imprinting stage and increase stable pressure on the tube body in the welding stage.

[0029] The vertical clamping part 2 includes a clamp 20, which is fixedly connected to the outer surface of the upper end of the base 1. The upper end of the clamp 20 is provided with a groove 21 matching the tube body. The upper end of the clamp 20 is rotatably connected to a lower pressure rod 22. The clamp 20 is vertically tightened and fixed to the tube body and is used in conjunction with the clamp 2 31.
