Abstract
Description
Technical Field
[0001] The utility model relates to an automatic cleaning device for a robot CO2 welding gun, which can be used in the process of robot automated CO2 welding (semi-automated welding) to regularly clean the residual spatter and garbage in the gun nozzle, thereby ensuring the welding quality of the welding robot. It belongs to the field of automated welding technology. Background Art
[0002] Currently, robotic CO2 welding production requires regular cleaning of the welding gun's shield nozzle to remove spatter and debris to ensure proper operation. Manual cleaning is prone to omissions, and the operator is within the dangerous range of the robot's rotation radius, making the operation cumbersome and time-consuming. Traditional gun cleaning devices are ineffective and can easily damage the inner surface of the shield nozzle, shortening its service life. Summary of the Invention
[0003] The technical problem to be solved by the utility model is how to regularly clean the shielding nozzle of the welding gun to remove spatter and debris during the production of robot CO2 welding, so that the CO2 gas shielding can fully protect the welding area and ensure the welding quality of the welding robot.
[0004] In order to solve the above problems: the utility model provides an automatic cleaning device for a CO2 welding gun, which includes a bell-shaped flexible wire brush for cleaning the gun muzzle. The bell-shaped flexible wire brush is arranged on a telescopic sleeve, and the telescopic sleeve is connected to the output end of the micro motor.
[0005] Preferably, a return spring is provided between the telescopic sleeve and the output end of the micro motor.
[0006] Preferably, a collection bin is provided below the bell-mouthed flexible wire brush.
[0007] Preferably, the micro motor is fixed on a bracket.
[0008] The utility model can regularly clean the spattering garbage remaining in the gun nozzle, thereby ensuring the normal operation of the welding gun, has a simple structure, is easy to manufacture and install, is easy to use, and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the present invention more clear and easy to understand, preferred embodiments are described in detail below with reference to the accompanying drawings.
[0016] Example
[0017] like Figure 1-5 As shown in the figure, the utility model provides a CO2 welding gun automatic cleaning device, which includes a bell-shaped flexible wire brush 3 for cleaning the gun muzzle, and the bell-shaped flexible wire brush 3 is arranged on a telescopic sleeve 4 (as shown in FIG. Figure 6 As shown, the smaller end of the bell-mouthed flexible wire brush 3 is inserted into the port of the telescopic sleeve 4, and the telescopic sleeve 4 is connected to the output end of the micro motor 5.
[0018] A return spring 7 is provided between the telescopic sleeve 4 and the output end of the micro motor 5 .
[0019] A collecting bin 6 is provided below the bell-mouthed flexible wire brush 3 .
[0020] The micro motor 5 is fixed on the bracket 2 .
[0021] A bell-shaped flexible wire brush 3 is mounted on the micro motor 5, and a telescopic sleeve 4 is mounted on the outside of the bell-shaped flexible wire brush 3. When the muzzle 1 is aligned and the telescopic sleeve 4 is pushed, the bell-shaped flexible wire brush 3 elastically expands and enters the cavity of the protective nozzle. The micro motor 5 rotates and drives the bell-shaped flexible wire brush 3 to rotate at a low speed. The bell-shaped flexible wire brush 3 cleans the inner wall of the protective nozzle and the outside of the conductive nozzle of the muzzle 1 and removes impurities, which fall into the collection bin 6. After the gun is cleaned, the muzzle 1 retreats and the telescopic sleeve 4 is reset.
