Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 As shown, a subway train roof assembly welding device includes two groups of support rods 1 in a group, and welding mechanisms 2 are installed on the tops of the two groups of support rods 1. The welding mechanism 2 includes a first slide 201, and the first slide 201 is installed on the tops of the two groups of support rods 1 respectively. A second slide 202 is installed between the two first slides 201, and the bottoms of both ends of the second slide 202 are slidably connected to the tops of the two first slides 201. A mounting plate 203 is slidably connected to one side of the second slide 202, and a robotic arm 204 is installed on one side of the mounting plate 203. A welding head 205 and an electric clamp 206 are installed on the bottom of the robotic arm 204, and dust suction mechanisms 3 are installed on both sides of the robotic arm 204.

[0023] As a technical optimization solution of the present invention, the two first slides 201 are parallel to each other and have equal heights, which facilitates smooth and stable sliding of the second slide 202 and enables the robotic arm 204 to work with high precision.

[0024] As a technical optimization solution of the present invention, reinforcing plates 4 are vertically installed on the bottom and top side walls of the four support rods 1, and the reinforcing plates 4 are triangular structures. Through the installation of multiple reinforcing plates 4, the support rods 1 and the bottom support of the first slide 201 are firm and stable, and have better pressure resistance.

[0025] As a technical optimization solution of the present invention, the angle between the welding head 205 and the electric clamp 206 is 45 degrees, and the welding head 205 and the electric clamp 206 are equal in length, which is beneficial for the welding head 205 and the electric clamp 206 to not interfere with each other when switching work, which is beneficial to normal welding or clamping work.

[0026] As a technical optimization solution of the present invention, control motors 208 are respectively installed on both sides of one end of the robotic arm 204. The top of the welding head 205 is rotatably connected to the robotic arm 204 through the cooperation of the control motor 208. The electric clamp 206 is rotatably connected to the robotic arm 204 through the cooperation of the rotating shaft 209 and the control motor 208. Through the operation of the two control motors 208, the rotation angles of the welding head 205 and the electric clamp 206 are respectively controlled.

[0027] As a technical optimization solution of the present invention, a storage groove 207 is provided on one side of the robotic arm 204, and both sides of the storage groove 207 extend to the outside of both sides of the robotic arm 204. The welding head 205 and the electric clamp 206 are rotatably connected inside the storage groove 207. The opening of the storage groove 207 facilitates the storage of the welding head 205 or the electric clamp 206 when they are not working.

[0028] As a technical optimization solution of the present invention, the dust suction mechanism 3 includes a dust suction pipe 301, and dust suction pipes 301 are respectively installed on both sides of the robotic arm 204. The dust suction pipe 301 is a cylindrical structure and is retractable. Through the installation of the dust suction pipe 301, it is convenient to connect with the external dust suction pipe 301 to realize the extraction of smoke generated during welding.

[0029] As a technical optimization solution of the present invention, a cover shell 302 is installed on both sides of the robotic arm 204, and a plurality of through holes 303 are provided on the cover shell 302. The dust suction pipe 301 is vertically connected to the side wall of one end of the cover shell 302. The installation of the cover shell 302 facilitates the connection of the dust suction pipe 301. The connection between the dust suction pipe 301 and the external pipeline is used to exhaust the inside of the cover shell 302, and the smoke is extracted and cleaned with the cooperation of the plurality of through holes 303.

[0030] As a technical optimization solution of the present invention, a filter screen 304 is respectively installed inside the multiple through holes 303, and one side of the filter screen 304 extends to the outside of the cover shell 302. The installation of the filter screen 304 prevents debris from being sucked into the cover shell 302 and causing pipe blockage.

The second slide 202 is connected with the two first slides 201 to realize the hanging installation of the mounting plate 203 and the mechanical arm 204. Under the control of the two first slides 201 and the second slide 202, the position of the mechanical arm 204 is adjusted to realize welding in different areas over a wide range. During welding, the two control motors 208 are rotated to store the electric clamp 206 in the storage slot 207, and the welding head 205 is rotated out to perform welding. Conversely, the welding head 205 is rotated and stored in the storage slot 207, and the electric clamp 206 is rotated out to perform clamping, thereby improving work efficiency and making operation more convenient. During welding, the dust suction pipe 301 is connected to the external dust suction pipe, so that the smoke is sucked into the cover 302 through the filter 304 and discharged through the dust suction pipe 301, thereby reducing pollution to the environment in the factory.
