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.

[0026] See also Figure 1-5 The auxiliary mechanism for automobile assembly welding in this embodiment includes a welding gun elbow 1, a front end connecting rod 2, a conductive nozzle 3, a welding wire 4 and a wind shield 5, and the above structure constitutes the front end wire outlet structure of the welding gun.

[0027] A front end connecting rod 2 is installed on the left side of the welding gun elbow 1, and a conductive nozzle 3 is threadedly connected to the other end of the front end connecting rod 2. A welding wire 4 passes through the inside of the welding gun elbow 1, the front end connecting rod 2 and the conductive nozzle 3.

[0028] In this embodiment, an installation and moving mechanism for installing and fixing the wind shield 5 is installed between the welding gun elbow 1 and the wind shield 5.

[0029] The installation and moving mechanism is used to install and move the wind shield 5 and to scrape off the welding slag attached to the inside of the wind shield 5 .

[0030] It should be noted that the installation moving mechanism includes a moving cylinder seat 8 movably sleeved on the outside of the welding gun bend 1, a scraper seat 6 installed on the left side of the welding gun bend 1, and a windproof cylinder 5 sleeved on the outside of the welding gun bend 1 and in contact with the scraper seat 6;

[0031] The windproof cylinder 5 is a stainless steel cylinder.

[0032] Among them, the outside of the windproof tube 5 is provided with a plurality of locking grooves 7 distributed in an annular shape and at equal distances, and a plurality of nuts 9 distributed in an annular shape and at equal distances are installed on the outside of the movable tube seat 8. The inner thread of the nut 9 is connected with a locking screw 10 inserted into the locking groove 7.

[0033] The locking groove 7 , the nut 9 and the locking screw 10 correspond one to one. The scraper seat 6 is annular and the end of the scraper seat 6 away from the welding gun elbow 1 is blade-shaped for easy scraping. The movable cylinder seat 8 is located outside the wind shield 5 .

[0034] The welding gun elbow 1 in this embodiment is provided with a driver for driving the installation moving mechanism to move back and forth.

[0035] It should be noted that the driver includes a guide movable groove 11 opened on the top of the welding gun elbow 1, a rack 12 installed on the right side of the movable cylinder seat 8 and slidably connected to the guide movable groove 11, and a heat insulation cover 13 installed on the top of the welding gun elbow 1.

[0036] The heat insulation cover 13 is a heat insulation material.

[0037] The heat shield 13 is provided with a through hole through which the rack 12 passes, and the heat shield 13 is provided with a meshing driving member that meshes with the rack 12 and drives the rack 12 to move left and right.

[0038] The meshing drive member includes a servo motor 14 mounted on the front surface of the heat shield 13 . A rotating shaft 15 rotatably connected to the inner wall of the heat shield 13 is mounted on the output shaft of the servo motor 14 . A toothed disc 16 meshing with the rack 12 is mounted outside the rotating shaft 15 .

[0039] A heat dissipation protection cover is installed and fixed to the outside of the servo motor 14 through fastening screws and the heat insulation cover 13 to protect the servo motor 14.

[0040] A slider slidably connected to the guide movable groove 11 is installed at the bottom of the rack 12.

[0042] By means of the nut 9, when the wind shield 5 is installed and fixed on the movable cylinder seat 8, the locking screw 10 is rotated and screwed into the inner thread of the nut 9, so that the locking screw 10 is inserted into the locking groove 7 provided on the wind shield 5, thereby realizing the installation and locking of the wind shield 5. Conversely, the wind shield 5 can be disassembled by rotating the locking screw 10 in the opposite direction.

[0043] Furthermore, when welding slag is attached to the wind shield 5 during welding, the servo motor 14 is provided to drive the toothed disc 16 on the rotating shaft 15 to rotate, while utilizing the meshing of the toothed disc 16 and the rack 12, and the limiting sliding of the rack 12 by the guide movable groove 11, thereby ensuring that when the toothed disc 16 rotates, the rack 12 is driven to move in a directional manner in the guide movable groove 11, thereby driving the movable cylinder seat 8 and the wind shield 5 to move in a synchronous combined manner, so that when the wind shield 5 moves, the scraper seat 6 fits tightly with the inner wall of the wind shield 5 to scrape off the welding slag attached to the inside of the wind shield 5, so as to avoid the welding slag clogging the wind shield 5 and making it impossible for the welding wire 4 to come out, and at the same time, it is also convenient for exposing the conductive nozzle 3 to grind the end face of the conductive nozzle 3 to remove the welding slag. Conversely, the servo motor 14 drives the rotating shaft 15 to rotate in the opposite direction to realize the movement and reset of the wind shield 5.

[0044] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
