Description

Technical Field

[0001] The utility model relates to the field of automobile beam welding, in particular to an automobile beam welding tool. Background Art

[0002] I-beams, also known as steel beams, are long strips of steel with an I-shaped cross-section. They are categorized into standard and lightweight I-beams. I-beams, such as automobile beams, require welding fixtures during the welding process. Currently, I-beams are typically spot welded during processing, and clamping equipment is often used during this process. Traditional clamping equipment is not secure, and during spot welding, the waist and leg plates can easily loosen, resulting in skewed welds. This affects the processing quality of the I-beams and their poor applicability, necessitating urgent improvements. Utility Model Content

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0017] like Figures 1 to 4In the embodiment of an automobile beam welding tool of the present invention shown, it includes a base plate 1 and an I-beam 2, a limiting groove 100 is provided on the top of the base plate 1, and a clamping assembly 3 for clamping the I-beam 2 is symmetrically slidably provided above the base plate 1, the clamping assembly 3 includes a "C"-shaped ring 31 and a clamping plate assembly 32 located in the C-shaped ring 31, the bottom of the "C"-shaped ring 31 is fixedly provided with a slider 30 that cooperates with the limiting groove 100, and a screw assembly 4 for driving the clamping assembly 3 to move closer to or away from each other is installed above the base plate 1. Specifically, the staff uses the screw to make the clamping ring assemblies move closer to or away from each other to adapt to the welding clamping of beams of different lengths; the "C"-shaped ring and the clamping plate assembly can quickly clamp the two ends of the beam to ensure the stability of the welding and improve the welding quality.

[0018] In one embodiment of the present application, the clamping plate assembly 32 includes a fixed clamping plate 320 fixedly connected to the inner wall of the "C"-shaped ring 31, a movable clamping plate 321 movable within the "C"-shaped ring 31, and a hydraulic cylinder 323 fixedly connected to the "C"-shaped ring 31. The output end of the hydraulic cylinder 323 is fixedly connected to the side of the movable clamping plate 321 away from the fixed clamping plate 320. Specifically, by quickly placing the I-beam 2 into the "C"-shaped ring 31 from the side, the movable clamping plate 321 is driven toward the fixed clamping plate 320 by the hydraulic cylinder 323 to stably clamp the upper and lower surfaces of the I-beam 2 to ensure the stability of the welding.

[0019] In one embodiment of the present application, the screw assembly 4 includes a motor 41, a bidirectional screw 42 fixedly connected to the output end of the motor 41, and a threaded drive block 43 fixedly connected to the "C"-shaped ring 31. The threaded drive blocks 43 are symmetrically distributed on the bidirectional screw 42. Specifically, the bidirectional screw 42 includes a first screw segment 421 and a second screw segment 422. The thread rotation directions of the first screw segment 421 and the second screw segment 422 are opposite. Specifically, the bidirectional screw 42 is driven to rotate by the motor 41. Since the thread rotation directions of the first screw segment and the second screw segment 422 are opposite, the threaded drive blocks 43 are driven to approach or move away from each other. The threaded drive blocks 43 drive the corresponding "C"-shaped rings 31 to approach or move away from each other, which is convenient for welding I-beams 2 of different lengths.

[0020] In one embodiment of the present application, a support plate assembly 5 is fixed in the "C"-shaped ring 31, and the support plate assembly 5 includes an I-beam side support plate 51 fixed in the "C"-shaped ring 31 and arranged perpendicular to the bottom plate, and an end support plate 52 fixed to one side of the I-beam side wall support plate 51. The end support plate 52 is in an "L" shape, and an auxiliary support flange 520 is fixed to the bottom of the end support plate 52. Specifically, the I-beam 2 side support plate 51 is used to press one side of the I-beam 2 so that the axis of the I-beam 2 is parallel to the axis of the bidirectional screw 42 to avoid tilting. The bottom of the I-beam 2 can be supported by the auxiliary support flange 520 to further ensure the reliability of clamping.

[0021] In one embodiment of the present application, a motor bracket 101 for supporting the motor 41 is fixedly provided on the top of the base plate 1, a middle support frame 102 for supporting the bidirectional screw 42 is fixedly provided in the middle of the base plate 1, and an end support frame 103 for supporting the bidirectional screw 42 is fixedly provided on the top of the base plate 1. Specifically, the middle support frame 102 and the end support frame 103 can ensure the stability of the bidirectional screw 42 during rotation.

[0022] In one embodiment of the present application, a weight-reducing hole 300 is provided on the “C”-shaped ring 31 .
