Technical Field
[0001] The present application relates to the technical field of semi-automatic flame cutting machines, and in particular to a cutting guide device of a semi-automatic flame cutting machine. Background Art
[0002] Semi-automatic flame cutting machines are multi-purpose gas cutting machines that use medium-pressure (or propane) and high-pressure oxygen to cut steel plates thicker than 5mm, primarily for straight-line cuts. They can also perform circular, bevel, and V-shaped cuts. In general, no further machining is required after cutting. They offer a compact structure, easy operation, safety, and minimal auxiliary time, significantly improving work efficiency. They are suitable for industries such as shipbuilding, machinery, steel structures, and construction, as well as for cutting steel plates in other large, medium, and small enterprises. Existing semi-automatic flame cutting machines rely heavily on the operator's skill and experience for precision and efficiency. Traditionally, linear guides have been used to guide the machine's reciprocating motion. However, this method is primarily suitable for horizontal cutting. Manual adjustments are required for curved steel plates, often resulting in poor cutting accuracy and efficiency, and potentially even leading to safety incidents.

[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The embodiment of the present application discloses a cutting guide device for a semi-automatic flame cutting machine. Figure 1-Figure 3 , including a guide rod 1, the outer wall of the guide rod 1 is provided with a sliding sleeve 14 for sliding, and a mounting sleeve 3 is provided on one side of the sliding sleeve 14. One end of the guide rod 1 is welded with a fixing part 7 in an integral structure, and is pre-fixed on the semi-automatic flame cutting machine body through the fixing part 7 for subsequent guidance. The outer wall of the guide rod 1 at one end away from the fixing part 7 is provided with a limiting sleeve 8 that provides limiting resistance to the sliding sleeve 14, which can prevent the sliding sleeve 14 from sliding off to one end and play a limiting role, and a reinforcement 13 is welded on the outer wall of one side of the sliding sleeve 14, and the end of the reinforcement 13 away from the sliding sleeve 14 is welded to the side wall of the mounting sleeve 3, so that as the sliding sleeve 14 slides, the mounting sleeve 3 can be driven to move horizontally on the guide rod 1.
[0020] Since a connector 15 is fixed in the center of the top of the sliding sleeve 14 in an integrated structure, the internal thread of the connector 15 is connected to a bolt 10, and one end of the bolt 10 extends into the interior of the sliding sleeve 14 and is movably connected to a tightening member 11. The tightening member 11 is set to a semi-arc structure and is made of non-slip material, which is convenient for fitting the outer wall of the guide rod 1. After the position of the sliding sleeve 14 is adjusted, the tightening member 11 is pushed close to the outer wall of the guide rod 1 by rotating the bolt 10 to position it, thereby completing the fixation.
[0021] like Figure 3 As shown, an adjusting screw 2 is installed at the bottom end of the mounting sleeve 3, and the bottom end of the adjusting screw 2 is fixedly connected to the connecting stud 4. A movable groove 12 is opened inside the mounting sleeve 3, and the end of the adjusting screw 2 away from the connecting stud 4 is threadedly connected to the inner wall of the movable groove 12. The adjusting screw 2 can be rotated and stored or extended in the inner thread of the movable groove 12, which is convenient for adjusting the height of the guide, and the outer wall of the adjusting screw 2 is threadedly connected to a fixing nut 9 for fixing the use distance of the fixing nut 9.
[0022] In addition, a rotating guide wheel 5 is provided on the outside of the bottom end of the connecting stud 4, and a rotating shaft 6 is fixedly installed on the bottom end of the connecting stud 4. The rotating shaft 6 is rotatably connected to the rotating guide wheel 5. By rotating the guide wheel 5 to fit the outer wall of the steel plate to be cut, it rotates along the curvature of the outer wall of the steel plate, thereby playing a good cutting guiding role.
[0023] The implementation principle of the cutting guide device of the semi-automatic flame cutting machine of the embodiment of the present application is as follows: when in use, the fixing part 7 is welded and fixed on the outer wall of the semi-automatic flame cutting machine body in advance, so that the guide rod 1 is installed. When the semi-automatic flame cutting machine is working, the sliding distance of the sliding sleeve 14 on the guide rod 1 can be adjusted, especially when cutting steel plates with curved cross-sections. The appropriate guide angle can also be adjusted by rotating the mounting sleeve 3 at the same time, and the movable extension distance of the adjusting screw 2 in the movable groove 12 can be adjusted to adjust the connecting stud 4 to a suitable guide height, and the rotating guide wheel 5 can be made to fit the outer wall of the steel plate. Then, the tightening part 11 is pushed to fit the outer wall of the guide rod 1 and fixed by tightening the bolt 10, so as to facilitate the cutting work of the cutting head of the semi-automatic flame cutting machine. As the cutting work of the semi-automatic flame cutting machine proceeds, the rotating guide wheel 5 will rotate outside the rotating shaft 6 and fit closely to the side wall of the steel plate for positioning, which plays a good guiding role in the cutting of the semi-automatic flame cutting machine and enables it to perform circular cutting motion.
