Description

Technical Field

[0001] This utility model belongs to the field of plate cutting technology, specifically relating to an adjustable cutting auxiliary tool for opening round holes in plates. Background Technology

[0002] In the construction and decoration process, it is often necessary to cut round holes in the middle of boards or cut round pieces from boards for later use. Existing large-scale automatic cutting equipment is inconvenient to set up on the construction site. Therefore, manual cutting or blanking is usually performed on-site using a cutting gun. When processing round holes with large outer diameters, operators first need to draw lines on the steel plate and then cut according to the marked lines. Because operators are prone to deviating when holding the cutting gun, the inner diameter of the cut round hole or the outer diameter of the round piece is irregular and has significant deviations, requiring subsequent re-adjustment. This is labor-intensive and affects construction efficiency. Utility Model Content

The position of the fixing member 4 on the rotating frame 3 has a degree of freedom for adjustment in the direction of approaching or moving away from the central reference block 2.

[0027] The adjustable cutting auxiliary tool for making circular holes in sheet metal provided in this embodiment, compared with the prior art, features a fixed base 1 that can be fixed to the ground. When cutting a steel plate, the steel plate can be placed on one side of the fixed base 1, and the position of the central reference block 2 can be adjusted so that the central reference block 2 is located at the center of the circle to be cut. Then, the position of the fixing member 4 on the rotating frame 3 is adjusted so that the distance between the cutting part of the cutting gun on the fixing member 4 and the axis of the rotating frame 3 on the central reference block 2 is the radius of the circle to be cut. Finally, the cutting gun is started, and the rotating frame 3 is rotated relative to the central reference block 2 to complete the circular cut. This method is convenient to operate, reduces the labor intensity of the operator, and the guide of the rotating frame 3 stabilizes the movement path of the cutting gun, ensuring consistent cutting quality.

[0028] Specifically, in this embodiment, the fixing member 4 is a clamp for fixing the cutting gun or a guide tube for placing the cutting gun. The specific structure is existing technology and will not be described here.

The position of the central reference block 2 on the crossbeam 6 has a degree of freedom to be adjusted along the length of the crossbeam 6. A guide rail arranged along the first direction is fixedly mounted on the fixed base 1. A slider that is slidably mounted on the guide rail is fixedly mounted on the bottom of the movable frame 5. A screw rod for abutting against the fixed base 1 is also threaded onto the movable frame 5. By rotating the screw rod, the screw rod can abut against the fixed base 1, thereby fixing the position of the movable frame 5. The crossbeam 6 is fixedly mounted on the movable frame 5 and extends outward in a horizontal direction on the movable frame 5. By adjusting the position of the movable frame 5 on the fixed base 1 and the position of the central reference block 2 on the crossbeam 6, the position of the central reference block 2 in the horizontal direction can be adjusted, which facilitates the positioning of the center position of the hole to be cut.
