[0002] A carbon arc gouging machine is a device that uses a carbon rod or a graphite rod as an electrode to generate an arc between the workpiece and melt the metal, and then blows away the molten metal.

[0003] However, due to different welding conditions, the types of carbon rods or graphite rods to be used need to be different, which will result in the diameter of the carbon rod or graphite rod to be adjusted. Most of the existing air planers can only match carbon rods or graphite rods of one diameter, which greatly affects the welding efficiency. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a highly adaptable carbon arc gouging machine, comprising a feeding box 1, openings 2 are provided on both sides of the feeding box 1, a main track 3 is installed in the feeding box 1, a pair of main slide blocks 5 are slidably connected to the main track 3, one end of the main shaft 6 is rotatably connected to the main slide block 5, and a feeding drum 8 is installed on the main shaft 6. Figure 1As shown, the central cross-sectional diameter of the feeding drum 8 is smaller than the cross-sectional diameters on both sides. This design prevents the carbon rods or graphite rods from moving easily during the feeding process, thereby ensuring that their charged state is not affected.

[0020] In order to ensure the activity stability of the feeding drums 8 on both sides and avoid the cantilever state, a sub-track 4 is also installed in the feeding box body 1. A pair of sub-sliders 7 are slidably connected to the sub-track 4. A motor 19 is embedded and installed in the sub-sliders 7, and the output end of the motor 19 is connected to the other end of the main shaft 6. The setting of the sub-track 4 can prevent the feeding drum 8 from tilting during the activity. At the same time, the rotation directions of the motors 19 on the upper and lower sides are opposite, so as to realize the feeding of carbon rods or graphite rods between the feeding drums 8. There are two main tracks 3 and two sub-tracks 4 to ensure the feeding state of carbon rods or graphite rods.

[0021] In order to provide a force for the feeding drums 8 on both sides to move toward each other, the side wall of the feeding box body 1 is provided with a socket 9, and a T-shaped movable block 10 is inserted into the socket 9. A spring 11 is installed between the T-shaped movable block 10 and the outer side wall of the feeding box body 1, and the spring 11 gives the T-shaped movable block 10 a force to move outward. The T-shaped movable block 10 is rotatably connected to one end of a pair of supporting arms 12, and the other ends of the pair of supporting arms 12 are rotatably connected to the main slider 5. Since the T-shaped movable block 10 has a tendency to move outward, it will drive the supporting arms 12 on both sides to rotate, so that the main slider 5 moves toward each other, thereby achieving the positioning effect of the feeding drum 8 for carbon rods or graphite rods of different diameters.

[0022] A discharge channel 13 is provided at the opening 2 on one side, and a power connection mechanism is provided in the discharge channel 13, so that the carbon rod or graphite rod can be charged, and it is also necessary to ensure that the entire loading box body 1 is in an insulating state. The power connection mechanism includes an insulating pad 14, and the channel side wall of the discharge channel 13 is provided with a sliding chamber 15 and an L-shaped power connection plate chamber 18 that are connected to each other, and the insulating pad 14 is slidably connected to the sliding chamber 15, and the side wall of the discharge channel 13 is provided with a screw hole 16, and a screw rod 17 is screwed in the screw hole 16, and the screw rod 17 is rotatably connected to the insulating pad 14. Through the matching effect between the threads, after the screw rod 17 is rotated, the insulating pad 14 moves downward, and ensures that the L-shaped power connection plate below the insulating pad 14 is in contact with the carbon rod or graphite rod.

[0023] Working principle: connect the workpiece to the negative pole of the power supply, and connect the end of the L-shaped power board to the positive pole of the power supply. When in use, rotate the screw 17 so that the insulating pad 14 presses the end of the L-shaped power board to contact the carbon rod or graphite rod in the channel, so that it is charged.

[0024] The carbon rod or graphite rod is passed through the opening 2 and placed between the upper and lower feeding drums 8. At this time, the spring 11 pushes the T-shaped movable block 10 and drives the support arm 12 to achieve the positioning and clamping of the material. At this time, the motor 19 is turned on to achieve the stable output of the carbon rod or graphite rod.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
