[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0018] like Figures 1-5As shown, the adjustable cutting device provided by the present invention includes: a mobile platform 1, a frame 2, a cross slide 3, a drive head 4, a cutting head assembly, an angle adjustment disk 5, a radius adjustment assembly, and a gas distribution valve 6. The frame 2 is fixedly installed on the mobile platform 1, the cross slide 3 is fixedly installed on the frame 2, the angle adjustment disk 5 is fixedly installed on the moving end of the cross slide 3, the drive head 4 is installed on the rotating end of the angle adjustment disk 5, the radius adjustment assembly is installed on the output end of the drive head 4, the cutting head assembly is fixedly installed on the radius rod 8 of the radius adjustment assembly, and the gas distribution valve 6 is fixedly installed on the frame 2 for controlling the gas distribution during the cutting process.

[0019] During the cutting operation, the cutting device can be quickly pushed to the working position by the moving carriage 1, improving operational flexibility. The horizontal position can be adjusted by the cross slide 3, and the pitch angle can be adjusted by the angle adjustment dial 5, enabling cutting in different directions. The radius adjustment component is driven by the drive head 4 to rotate, realizing the cutting of arc structures and the adjustment of the rotation angle. The radius adjustment component can cut circles of different radii and can also intuitively read the radius of the cutting circle, effectively improving the cutting accuracy of the cutting circle radius and shortening the parameter adjustment time. The automatic control of gas distribution during the cutting process by the gas control valve can effectively improve the cutting quality.

[0020] Furthermore, the radius adjustment assembly includes: a center rod 7, a radius rod 8, and a control block 9. The center rod 7 is mounted on the output end of the drive head 4, the control block 9 is slidably mounted on the center rod 7, and the radius rod 8 is slidably mounted on the control block 9 and is perpendicular to the center rod 7.

[0021] When adjusting the radius, the relative position of the radius rod 8 and the center rod 7 can be adjusted to easily modify the cutting radius, effectively shortening the parameter adjustment time, improving cutting efficiency, and allowing for a direct reading of the cutting circle radius, thus improving cutting accuracy (the accuracy using this device is ±0.2mm, while the accuracy using the template scribing method is ±1mm). By controlling the sliding motion of the control block 9 on the center rod 7, the height of the cutting torch of the cutting head assembly can be adjusted.

[0022] Furthermore, the cutting head assembly includes a lower probe 10 and a cutting torch 11. The lower probe 10 is slidably mounted on the radius rod 8 and is arranged parallel to the center rod 7. The cutting torch 11 is fixedly mounted on the end of the lower probe 10 away from the radius rod 8.

[0023] By mounting the cutting torch 11 on the lower probe rod 10, the torch height of the cutting torch 11 can be easily adjusted for fine-tuning, effectively shortening the parameter adjustment time and improving cutting efficiency.

[0024] Furthermore, the lower probe 10 is provided with a scale.

[0025] By setting a scale on the lower probe rod 10, the adjustment accuracy of the cutting torch height of the cutting torch 11 can be improved.

[0026] Furthermore, the mobile platform 1 includes: a vehicle body 101, casters 102, and a push handle 103. The casters 102 are mounted on the bottom surface of the vehicle body 101, and the push handle 103 is fixedly mounted on the side wall of the vehicle body 101.

[0027] The omnidirectional wheels 102 improve the flexibility of the vehicle body 101 during movement, and the push handle 103 facilitates the pushing of the vehicle body 101.

[0028] Furthermore, the frame 2 includes: a column 201 and a crossbeam 202. The column 201 is fixedly installed on the mobile platform 1, and the crossbeam 202 is arranged in the horizontal direction and slidably connected to the column 201.

[0029] By adopting the combination of column 201 and crossbeam 202 in the stroke frame 2, a stable support can be provided for the cutting device. By moving the crossbeam 202 on the column 201, a large-scale movement of the cutting position can be achieved, thereby enabling the cutting of multiple areas after one clamping, reducing the number of clamping operations and improving cutting efficiency.
