Description

Technical Field

[0001] This utility model relates to the field of laser welding equipment technology, and in particular to a laser welding machine with controllable welding head oscillation amplitude. Background Technology

[0002] In the field of laser welding, different welding tasks, such as welding workpieces of different shapes and sizes, or requiring different welding ranges and precisions during the welding process, often necessitate adjusting the oscillation amplitude of the welding head. Traditional laser welding machines have fixed or inconveniently adjustable welding head oscillation amplitudes, making it difficult to meet diverse welding needs, resulting in low welding efficiency, unstable welding quality, and an inability to adapt to complex welding conditions. Therefore, developing a laser welding machine capable of freely adjusting the welding head oscillation amplitude according to welding requirements is of significant practical importance.

[0003] Therefore, the existing laser welding equipment technology field needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a laser welding machine with controllable welding head oscillation amplitude. It can freely adjust the position of the radial adjustment shaft structure according to welding requirements, thereby changing the left and right reciprocating amplitude of the transverse welding component, achieving a wider range of welding, improving welding efficiency and quality, and adapting to diverse welding conditions.

[0005] To achieve the above objectives, the present invention adopts the following solution: a laser welding machine with controllable welding head oscillation amplitude, comprising a rotary motor assembly, a rotary circular plate provided at the output end of the rotary motor assembly, a radial adjustment shaft structure provided at the end face of the rotary circular plate, a transverse welding assembly provided below the rotary motor assembly, and a reciprocating linkage assembly provided between the radial adjustment shaft structure and the transverse welding assembly.

[0006] Furthermore, the rotary motor assembly includes a motor mounting bracket on which a drive motor is mounted.

[0007] Furthermore, the radial adjustment shaft structure includes a radial guide groove disposed on the rotating circular plate, a radial slider movably disposed within the radial guide groove, an eccentric adjustment shaft disposed on the radial slider, and a lead screw adjustment assembly disposed between the radial guide groove and the radial slider.

[0008] Furthermore, the lead screw adjustment assembly includes a lead screw mounting hole rotatably mounted at the end of the radial guide groove, an adjustment lead screw is rotatably mounted in the lead screw mounting hole, the adjustment lead screw is arranged along the path of the radial guide groove, the radial slider is provided with a screw hole, and the adjustment lead screw passes through the screw hole and is threadedly connected to the screw hole.

[0009] Furthermore, the transverse welding assembly includes a connecting frame fixedly connected to the motor mounting bracket, a transverse slide rail is provided on the connecting frame, a transverse slider is provided on the transverse slide rail, and a welding assembly is provided on the transverse slider.

[0010] Furthermore, the reciprocating motion linkage component includes a drive plate disposed on the radial slider, the drive plate being provided with a vertical straight groove, and the eccentric adjustment shaft being movably installed in the vertical straight groove.

[0011] In summary, the advantages of this utility model over the prior art are:

[0012] This invention addresses the shortcomings of existing laser welding equipment technology. Through its structural design, it offers the following advantages: precise control of the oscillation amplitude; the radial slider's position within the radial guide groove is precisely adjusted via a lead screw adjustment assembly, thereby changing the eccentricity of the eccentric adjustment shaft and achieving precise control of the left-right reciprocating amplitude of the transverse welding assembly. This meets the oscillation amplitude requirements of different welding tasks. It also offers a large welding range: the oscillation amplitude of the welding head can be freely adjusted according to welding needs, enabling welding over a wider range and adapting to workpieces of different shapes and sizes. Furthermore, it improves welding quality and efficiency: welding parameters can be flexibly adjusted, making the welding process more stable and precise, thus improving welding quality and efficiency and reducing production costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Fix the motor mounting bracket 101 in a suitable working position, ensure that the drive motor 102 is securely installed, and connect the power supply and control system.

[0020] The connection between the rotating circular plate 2 and the output end of the drive motor 102 ensures that the rotating circular plate 2 can rotate flexibly.

[0021] According to the welding requirements, start the drive motor 102 to drive the rotating circular plate 2 to rotate.

[0022] To adjust the oscillation amplitude of the welding head, rotate the adjusting screw 3042. When the adjusting screw 3042 rotates, it is connected to the screw hole on the radial slider 302 by thread, which causes the radial slider 302 to move within the radial guide groove 301, thereby changing the position of the eccentric adjusting shaft 303 relative to the center of the rotating circular plate 2, that is, changing the eccentricity.

[0023] As the rotating disc 2 rotates, the eccentric adjustment shaft 303 moves within the vertical groove 502, driving the transverse welding assembly 4 to reciprocate via the drive plate 501. Due to the change in eccentricity, the left and right reciprocating amplitude of the transverse welding assembly 4 also changes accordingly, thereby adjusting the oscillation amplitude of the welding head.

[0024] During the welding process, the adjusting screw 3042 can be adjusted at any time according to the actual situation to obtain the best welding effect.

[0027] The lead screw adjustment assembly 304 of this utility model includes a lead screw mounting hole 3041 rotatably mounted at the end of the radial guide groove 301. An adjustment lead screw 3042 is rotatably mounted in the lead screw mounting hole 3041. The adjustment lead screw 3042 is arranged along the path of the radial guide groove 301. A screw hole is provided on the radial slider 302. The adjustment lead screw 3042 passes through the screw hole and is threadedly connected to the screw hole.
