Description

Technical Field

[0001] This utility model relates to the field of carbon arc air gouging technology, and in particular to a 360-degree circumferential air-supplying carbon arc air gouging gun. Background Technology

[0002] Carbon arc gouging utilizes the high temperature generated by an electric arc between a carbon rod (as an electrode) and the workpiece to melt the metal. Compressed air is then used to blow away the molten metal, creating grooves or removing defects from the metal surface. However, existing carbon arc gouging guns are typically connected to power cords and air supply lines via fixed connections. This rigid connection restricts the rotation of the gun body. On one hand, operators need to constantly adjust the position of their arm or body during complex or delicate machining, increasing the difficulty and fatigue of operation. On the other hand, the power cord and air supply lines may become tangled as the operator moves, further affecting operational flexibility and safety. Utility Model Content

An air-electric assembly 4 is connected to the end of the air-electric connecting rod 2 away from the gun head 1, and the air-electric assembly 4 is rotatably connected to the air-electric connecting rod 2.

[0029] In this embodiment of the carbon arc gouging gun, the pneumatic-electric assembly 4, used to connect the power cord and the air supply line, is rotatably connected to the pneumatic-electric connecting rod 2, solving the technical problem in the prior art where the power cord and air supply line restrict the rotation of the gun body. During operation, the carbon arc gouging gun can freely adjust its angle, allowing operators to perform various complex or fine machining operations more flexibly without frequently adjusting their body or arm positions, reducing operational difficulty and fatigue. Simultaneously, the power cord and air supply line can naturally swing with the rotation of the gun body, reducing the possibility of entanglement and improving work efficiency and safety.

[0030] In some embodiments, the gun head 1, the pneumatic-electric connecting rod 2, and the pneumatic-electric assembly 4 are all made of conductive materials, and the pneumatic-electric connecting rod 2 has a hollow structure. The gun head 1 is provided with a conductive nozzle 131 and an air nozzle 132, and the pneumatic-electric assembly 4 is provided with an air source connection channel 431 and a power connection end 432. One end of the pneumatic-electric connecting rod 2 is connected to the gun head 1 by a thread and communicates with the air nozzle 132 on the gun head 1. The other end of the pneumatic-electric connecting rod 2 is rotatably connected to the pneumatic-electric assembly 4 and communicates with the air source connection channel 431 on the pneumatic-electric assembly 4.

[0031] refer to Figure 2 As shown, specifically, the gun head 1 includes a cylindrical inner core 13, a cylindrical outer core 12 sleeved on the outside of the inner core 13, and an insulating outer sleeve 11 sleeved on the outside of the outer core 12. A conductive nozzle 131 for fixing a carbon rod is provided on the center line of the inner core 13. The gun head 1 also includes a carbon rod fixing member 14 arranged perpendicular to the axial direction of the gun head 1. The carbon rod fixing member 14 applies a force perpendicular to the axial direction to the carbon rod inserted into the conductive nozzle 131, thereby restricting the relative movement between the carbon rod and the conductive nozzle 131. A circumferential first air delivery groove 1321 is provided on the outer surface of the inner core 13, and six axial second air delivery grooves 1322 are also provided on the outer surface of the inner core 13. The second air delivery grooves 1322 are interconnected with the first air delivery grooves 1321. The outer core 12 and the inner core 13 are fitted with an interference fit, so that the outer core 12 is tightly fitted on the outside of the inner core 13. The second air supply groove 1322 and the first air supply groove 1321 are respectively surrounded by the outer core 12 to form the air supply nozzle 132.

[0032] refer to Figure 3 As shown, in some embodiments, the pneumatic-electric combination 4 includes a first connecting body 41 and a second connecting body 43. The power connection end 432 and the air source connection channel 431 are both located on the side of the second connecting body 43 away from the first connecting body 41. The first connecting body 41 and the second connecting body 43 are enclosed together to form a rotating chamber communicating with the air source connection channel 431. The first connecting body 41 is provided with a through hole for the pneumatic-electric connecting rod 2 to pass through. One end of the pneumatic-electric connecting rod 2 that passes through the through hole and enters the rotating chamber is connected to a rotor 42 that is rotatably connected to the rotating chamber. The rotor 42 is provided with an air inlet for communicating with the air source connection channel 431 and the pneumatic-electric connecting rod 2.

[0033] During operation, on the one hand, the current in the power supply is conducted from the power connection terminal 432 on the second connection body 43 to the fine rotor 42 to the pneumatic connection rod 2, and finally reaches the conductive nozzle 131 on the gun head 1, and acts on the carbon rod in the conductive nozzle 131. The high-temperature electric arc generated by the carbon rod at high temperature melts the metal surface.

[0034] On the other hand, the compressed gas in the gas source pipeline flows from the gas source connection channel 431 on the second connecting body 43, through the air inlet on the rotor 42 to the pneumatic connecting rod 2, and finally is ejected from the air nozzle 132 on the gun head 1 to blow away the molten metal, thereby achieving the processing of the metal surface.

[0035] In some embodiments, the first connecting body 41 and the second connecting body 43 are connected by threads, and the pneumatic connecting rod 2 is connected to the rotor 42 by threads.

[0036] In some embodiments, a seal 421 is provided between the outer peripheral surface of the rotor 42 and the sidewall of the rotating chamber. The seal 421 prevents compressed gas from leaking from the gap between the rotor 42 and the sidewall of the rotating chamber, which is crucial for maintaining the stability and efficiency of the air gouging process.

[0037] In some embodiments, a sealing element 421 is connected between the pneumatic connecting rod 2 and the through hole on the first connecting body 41.

[0038] In some embodiments, the handle 3 includes a middle sleeve 32 sleeved on the outside of the air intake rod 21, an upper sleeve 31 at the end of the middle sleeve 32 near the nozzle 1, and a lower sleeve 33 at the end of the middle sleeve 32 away from the nozzle 1, sleeved on the outside of the circuit connector 22. The upper sleeve 31 and the lower sleeve 33 are made of high-temperature resistant nylon material, while the middle sleeve 32 is made of bakelite material. The inner side of the end of the middle sleeve 32 near the nozzle 1 has a sleeve cavity 321, thereby reducing contact with the air intake rod 21 and improving the heat insulation effect.

[0039] In some embodiments, the power connection terminal 432 is connected to a power fixing member 433 for fixing the power connector, and the air source connection channel 431 is connected to an air source switch member 434 for controlling the on / off of the air path.

[0040] refer to Figure 4 As shown, in some embodiments, an angle adjustment sleeve 34 is fitted onto the pneumatic-electric assembly 4. The power supply fixing member 433 and the air source switch member 434 pass through the angle adjustment sleeve 34 and extend to its outer side. The angle adjustment sleeve 34 is rotatably connected to the end of the handle 3 away from the nozzle 1. During operation, the angle adjustment sleeve 34 can rotate together with the pneumatic-electric assembly 4.
