Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-6 , an embodiment provided by the present invention: A steel door body assembly line welding equipment, including a conveyor belt 1, a steel door body 3, a frame 4 and a welding torch 9. The conveyor belt 1 conveys the steel door body 3. At both ends of the top of the conveyor belt 1, there are housings 2 on both sides, and movable plates 24 are arranged inside the housings 2. Guide wheels 8 are evenly arranged on the side of the movable plate 24 close to the steel door body 3, and the guide wheels 8 are in contact with both sides of the steel door body 3.

[0022] The steel door body 3 is transported on the assembly line through the conveyor belt 1. During the transportation process, the guide wheels 8 limit both sides of the steel door body 3 to prevent it from deviating and shifting. On the outside of the housing 2, there are first cylinders 7, and the output ends of the first cylinders 7 are connected to the movable plates 24 through telescopic rods. The first cylinder 7 can push the movable plate 24 to move, so as to adjust the position of the guide wheel 8, so that it can limit steel door bodies 3 of different widths.

[0023] On both sides inside the housing 2, there are guide grooves 23. On both sides of the movable plate 24, there are guide blocks that match the guide grooves 23 to guide and limit the movable plate 24. At the central position of the top of the conveyor belt 1, there is a frame 4 erected. At the central position inside the frame 4, there is a mounting plate 25. At one end of the bottom of the mounting plate 25, there is an adjustment chamber 12. On one side of the adjustment chamber 12, there is a transmission shaft 16 arranged through a bracket 19. An adjustment part 20 is arranged on the transmission shaft 16, and one end of the adjustment part 20 is connected to a welding torch 9.

[0024] At the top inside the frame body 4, a lead screw 13 is provided, and a driving block 14 is sleeved on the lead screw 13. The bottom end of the driving block 14 is fixedly connected to the mounting plate 25 through a second air cylinder 11. When the steel door main body 3 is conveyed below the frame body 4, the second air cylinder 11 pushes the mounting plate 25 to descend to the welding position, and the four peripheral frames of the steel door main body 3 are welded and fixed by the welding torch 9.

[0025] At the central position inside the adjustment chamber 12, a second rotary driving mechanism 15 is provided. The output end of the second rotary driving mechanism 15 is provided with a driving gear 18 through a roller, and a driven gear 17 meshing with the driving gear 18 is provided on the transmission shaft 16. The second rotary driving mechanism 15 can drive the driving gear 18 to rotate. The driven gear 17 meshes with the driving gear 18, so that the driven gear 17 and the transmission shaft 16 rotate, and the adjustment part 20 drives the welding torch 9 to rotate around the bracket 19, thereby adjusting the welding angle of the welding torch 9 and facilitating the welding operation on the four sides of the steel door main body 3.

[0026] At the top of one side of the frame body 4, a first rotary driving mechanism 5 is fixed, and the output end of the first rotary driving mechanism 5 is connected to the lead screw 13. At the same time, the first rotary driving mechanism 5 can drive the lead screw 13 to rotate, so that the driving block 14 translates along the lead screw 13, and the horizontal position of the welding torch 9 can be adjusted to meet different welding requirements.

[0027] At the central position of one side of the frame body 4, a purification box 6 is provided. At one end of the bottom of the mounting plate 25, a dust collector 10 is provided, and the output end of the dust collector 10 is connected to the purification box 6 through an air duct 21. At the central position inside the purification box 6, a filter screen 22 is provided, and the filter screen 22 is made of activated carbon material.

[0028] The dust collector 10 works during welding, conveys the gas generated by welding to the purification box 6 through the air duct 21, and the dust-containing gas is filtered and purified by the filter screen 22 and then discharged, reducing the pollution to the working environment. The specific model specifications of the first rotary driving mechanism 5, the second rotary driving mechanism 15, the first air cylinder 7, the second air cylinder 11, and the dust collector 10 need to be determined by selection calculation according to the specification parameters of the device. The selection calculation method is the prior art, so it will not be elaborated in detail.

[0029] When this equipment needs to work, the steel door body 3 is transported on the assembly line through the conveyor belt 1. During the transportation process, the two sides of the steel door body 3 are limited by the guide wheels 8 to prevent deviation and displacement. At the same time, the first cylinder 7 can push the movable plate 24 to move, thereby adjusting the position of the guide wheels 8 so that they can limit steel door bodies 3 with different widths. When the steel door body 3 is transported below the frame 4, the second cylinder 11 pushes the mounting plate 25 down to the welding position, and the four surrounding frames of the steel door body 3 are welded and fixed by the welding torch 9. The second rotation drive mechanism 15 can drive the driving gear 18 to rotate. The driven gear 17 meshes with the driving gear 18, causing the driven gear 17 and the transmission shaft 16 to rotate, so that the adjusting part 20 drives the welding torch 9 to rotate around the bracket 19, thereby adjusting the welding angle of the welding torch 9 to facilitate the welding operation on the four sides of the steel door body 3.

[0030] The first rotation drive mechanism 5 can drive the lead screw 13 to rotate, causing the drive block 14 to translate along the lead screw 13, so as to adjust the horizontal position of the welding torch 9 to meet different welding requirements. The vacuum cleaner 10 works during welding, and conveys the welding-generated gas through the air duct 21 to the purification box 6. The dust-containing gas is filtered and purified by the filter screen 22 and then discharged to reduce the pollution to the working environment.
