Description

Technical Field

[0001] This utility model relates to the field of gas cutting machines, specifically a mobile gas cutting machine. Background Technology

[0002] Currently, gas cutting operations mainly rely on manual hand-held cutting torch operation. Manual operation makes it difficult to guarantee the stability of straight lines or complex trajectories. Especially when cutting large plates, problems such as cutting line deviation and uneven edges are prone to occur, affecting the quality of subsequent welding or assembly. Operators need to maintain a fixed posture for a long time and manually adjust the flame and move the cutting torch, which consumes a lot of physical strength and is inefficient. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a mobile gas cutting machine.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A mobile gas cutting machine includes a support frame; casters are installed at the four corners of the bottom of the support frame, and a top plate is fixedly connected to the top of the support frame. A worm gear screw jack is fixedly installed in the center of the top of the top plate. Two slide rails are fixedly connected to the left and right inner walls of the support frame, and the two slide rails on the same side are symmetrically distributed front and back. A transverse linear module is provided between the four slide rails. Slider blocks are fixedly connected to the left and right ends and front and back sides of the transverse linear module. The sliders are slidably engaged with the slide rails. The screw of the worm gear screw jack passes through the top plate and is threadedly connected to the top plate. The bottom end of the screw of the worm gear screw jack is rotatably connected to the center of the top of the transverse linear module. A longitudinal linear module is provided at the bottom of the transverse linear module. The transverse linear module and the longitudinal linear module have the same structure. Both the horizontal linear module and the vertical linear module include guide rails, a ball screw, a handwheel, and a movable seat. The two guide rails are parallel, and the ball screw is located between the two guide rails. One end of the ball screw passes through the horizontal and vertical linear modules. The handwheel is fixedly connected to one end of the ball screw. A locking nut is threaded onto the outer wall of the end of the ball screw connected to the handwheel. The outer wall of the locking nut abuts against the outer walls of the horizontal and vertical linear modules. The top of the movable seat is slidably engaged with the two guide rails. The top center of the movable seat is threadedly connected to the ball screw. The upper middle position of the vertical linear module is fixedly connected to the bottom of the movable seat of the horizontal linear module. A flame gun is fixedly installed at the bottom of the movable seat of the vertical linear module. The worm input end of the worm gear screw jack is fixedly connected to a second handwheel.

[0006] A slide rail two is fixedly connected to one side edge of the longitudinal linear module. Several movable plates are slidably sleeved on the slide rail two. A conveying pipe is fixedly connected between the movable plates. One end of the conveying pipe is connected to the flame gun.

[0007] The beneficial effects of this utility model are:

[0008] This invention achieves three-dimensional fine-tuning of the flame gun through a worm gear screw jack, a horizontal linear module, and a vertical linear module, enabling precise manual cutting. It allows for accurate control of the cutting position and angle, and is suitable for workpieces with complex shapes. Attached Figure Description

[0014] like Figure 1-4As shown: A mobile gas cutting machine includes a support frame 1; casters 2 are installed at the four corners of the bottom of the support frame 1; a top plate 3 is fixedly connected to the top of the support frame 1; a worm gear screw jack 4 is fixedly installed at the top center of the top plate 3; two slide rails 7 are fixedly connected to the left and right inner walls of the support frame 1, and the two slide rails 7 on the same side are symmetrically distributed front and back; a transverse linear module 5 is provided between the four slide rails 7; sliders 8 are fixedly connected to the left and right ends and front and back sides of the transverse linear module 5; the sliders 8 are slidably engaged with the slide rails 7; the screw of the worm gear screw jack 4 passes through the top plate 3; the screw of the worm gear screw jack 4 is threadedly connected to the top plate 3; the bottom end of the screw of the worm gear screw jack 4 is rotatably connected to the top center of the transverse linear module 5; a longitudinal linear module 6 is provided at the bottom of the transverse linear module 5; the transverse linear module 5 and the longitudinal linear module 6 have the same structure; the transverse linear module 5 and the longitudinal linear module 6 are... Each linear module 6 includes a guide rail 13, a ball screw 14, a handwheel 15, and a movable seat 9. The two guide rails 13 are parallel to each other, and the ball screw 14 is located between the two guide rails 13. One end of the ball screw 14 passes through the transverse linear module 5 and the longitudinal linear module 6. One end of the ball screw 14 is fixedly connected to the handwheel 15. The outer wall of the end of the ball screw 14 connected to the handwheel 15 is threaded with a locking nut 16. The outer wall of the locking nut 16 abuts against the outer walls of the transverse linear module 5 and the longitudinal linear module 6. The top of the movable seat 9 is slidably engaged with the two guide rails 13. The top middle of the movable seat 9 is threadedly connected to the ball screw 14. The upper middle position of the longitudinal linear module 6 is fixedly connected to the bottom of the movable seat 9 of the transverse linear module 5. The bottom of the movable seat 9 of the longitudinal linear module 6 is fixedly installed with a flame gun 10. The worm input end of the worm gear screw jack 4 is fixedly connected to the handwheel 2 41.

[0015] A slide rail 2 11 is fixedly connected to one side edge of the longitudinal linear module 6. Several movable plates 12 are slidably sleeved on the slide rail 2 11. A conveying pipe 17 is fixedly connected between the movable plates 12. One end of the conveying pipe 17 is connected to the flame gun 10.

[0016] The bottom casters 2 enable flexible movement of the entire equipment, facilitating transfer between different work sites.

[0017] Height adjustment: Turning handwheel 41 drives the worm gear screw jack 4, which in turn moves the horizontal linear module 5 up and down, thereby adjusting the vertical height of the flame gun 10 to meet the cutting needs of workpieces of different thicknesses.

[0018] Lateral movement: Rotate the handwheel 15 of the lateral linear module 5 to drive the ball screw 14 to rotate, causing the moving seat 9 to slide along the guide rail 13, which in turn drives the longitudinal linear module 6 and the flame gun 10 to move left and right, thus achieving lateral cutting.

[0019] Longitudinal movement: The longitudinal linear module 6 drives the flame gun 10 to move back and forth using the same principle, and combined with lateral movement, it can achieve complex trajectory cutting.

[0020] The gas is supplied to the flame gun 10 through the delivery pipe 17. After ignition, the workpiece is preheated to the ignition point and a high-speed oxygen stream is sprayed to achieve metal oxidation cutting.

[0021] The movable plate 12 on the slide rail 2 11 can adjust the position of the delivery pipe 17 to ensure a stable gas supply to the flame gun 10.

[0022] During the cutting process, the ball screw 14 is fixed by the locking nut 16 to prevent the moving seat 9 from being accidentally displaced and to ensure cutting accuracy.

[0023] This utility model only protects the mechanical parts; the functions implemented by the software control part are not within the scope of protection of this utility model.
