[0024] See also Figures 1 to 4 The utility model provides a technical solution: a supporting device for a flame cutting machine, comprising a clamping mechanism for fixing a cutting gun and a three-axis frame body for driving the clamping mechanism to perform three-axis motion.

[0025] The clamping mechanism includes a strip-shaped mounting plate 1, and at least one fixing seat 3 is installed on one side of the strip-shaped mounting plate 1. In this solution, the number of fixing seats 3 is two. If the length of the cutting gun is large, three or more fixing seats 3 can be set corresponding to the length. Figure 1 As shown, the other end of the fixed seat 3 is provided with an arc groove 2, and a rotating seat 4 is provided on one end surface of the arc groove 2. A rectangular opening 5 is opened in the middle of the rotating seat 4, and a rotating block 8 is rotatably provided in the rectangular opening 5. One end of the rotating block 8 is connected to the end of the arc clamping plate 9. A rotating member is formed between the rotating block 8 and the rotating seat 4, so that the arc clamping plate 9 can rotate freely around the rotating member, as shown in FIG. Figure 1 As shown, when the arc-shaped clamping plate 9 is closed on the arc-shaped groove 2, the cavity formed by the arc-shaped groove 2 and the arc-shaped clamping plate 9 is used to place the tube body of the cutting gun.

[0026] The other end of the arc-shaped card plate 9 is connected to the card seat 10, and the card seat 10 is placed on the other side end surface of the arc groove 2. The end of the card seat 10 away from the arc-shaped card plate 9 extends to the outside of the fixed seat 3 and is connected to the strip seat 16. The strip seat 16 is placed on the side of the fixed seat 3. The end of the strip seat 16 is connected to a pressing seat 13 perpendicular to the strip seat 16. The end of the pressing seat 13 is provided with a bayonet 17. The set pressing seat 13 can also be used as a handle. In the actual use process, the pressing seat 13 can be held by hand to lift the arc-shaped card plate 9 or cover the arc groove 2;

[0027] A certain distance is set between the clamping seat 13 and the strip mounting plate 1, and a certain distance is also set between the strip seat 16 and the side of the fixing seat 3 to prevent the two from touching each other. A mounting shaft 27 perpendicular to the bayonet 17 is provided below the clamping seat 13, and both ends of the mounting shaft 27 are rotatably mounted in the support 14, and the support 14 is connected to the strip mounting plate 1. A fastening screw 11 is vertically connected to the middle of the mounting shaft 27, and a fastening knob 12 is threadedly mounted on the fastening screw 11. A limit block 18 is provided at the end of the fastening screw 11 to prevent the rotating fastening knob 12 from falling off, and the edge of the fastening knob 12 is provided with anti-slip grooves.

[0028] When in use, rotate the fastening knob to the top of the fastening screw, then turn the fastening screw 11 into the bayonet 17, and then rotate the fastening knob 12 to press its end face against the pressing seat 13, so that the pressing seat 13 drives the strip seat 16 and the arc-shaped clamping plate 9 to move downward, allowing the arc-shaped clamping plate 9 to firmly clamp the tube body of the cutting gun to fix the cutting gun. When the cutting gun needs to be replaced or the nozzle at the bottom of the cutting gun needs to be replaced, it is only necessary to loosen the fastening knob 12 to separate the fastening knob 12 from the pressing seat 13, remove the fastening screw 11 from the bayonet 17, and then lift the arc-shaped clamping plate 9 to remove the cutting gun.

[0029] Furthermore, two limit seats 15 are provided at one end of the arc groove 2 away from the rotating member, and the holder 10 is placed between the two limit seats 15 with clearance fit, which can enhance the stability of the holder 10. The holder 10 can be limited by directly placing it on the two limit seats 15.

[0031] The three-axis frame is installed on the cutting bed. The specific structure of the three-axis frame includes two first mounting beams 21 arranged in parallel. Specifically, the first mounting beams 21 are installed on the cutting bed. The tops of the first mounting beams 21 are both installed with first linear drive modules 19. The tops of the two first linear drive modules 19 are both installed with support frames 20. The tops of the two support frames 20 are connected by a second mounting beam 25.

[0032] A second linear drive module 24 is provided on the top of the second mounting beam 25, a connecting seat 22 is provided on one side of the second mounting beam 25, the top of the connecting seat 22 is connected to the second linear drive module 24, a third linear drive module 23 is vertically downwardly installed on the side of the connecting seat 22, and the bottom of the third linear drive module 23 is installed in the mounting hole 6;

[0033] Specifically, the first linear drive module 19 can drive the cutting gun to move forward and backward, the second linear drive module 24 drives the cutting gun to move left and right, and the third linear drive module 23 drives the cutting gun to move up and down, so that the cutting gun can reach any position within the plane. The first linear drive module 19 and the second linear drive module 24 are screw linear drive modules or private service linear motors, and the third linear drive module 23 is a pneumatic linear drive module. Of course, the third linear drive module 23 can also be a screw linear drive module or a private service linear motor.

[0034] Furthermore, a guide rail 26 is provided on the side of the second mounting beam 25, and the guide rail 26 is connected to the connecting seat body 22 through a slider. The guide rail 26 can also be set on the first mounting beam 21, so that the guide rail 26 and the support frame 20 are connected through the slider, so that the support frame 20 can have higher stability.

[0035] The working mode of the utility model is that the cutting gun can not only reach any position in the plane, but most importantly, the cutting gun is easy to replace, that is, the tube body of the cutting gun is placed in the arc groove 2, and then the arc clamping plate 9 is clamped on the tube body, and finally the cutting gun is firmly fixed by tightening the tightening knob 12. When the cutting gun needs to be disassembled, it only needs to loosen the tightening knob, which plays the role of convenient installation and convenient disassembly.

[0036] Based on the above embodiment, it can be further optimized that a certain distance (such as Figure 3 In this way, the holder 10 can have a certain movable distance, so that the holder 10 can be better stuck on the cutting gun.
