[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1-5The utility model provides an embodiment: a welding device for processing angle steel flange, including a processing table 1, slot openings 2 are opened on both sides of the front end of the processing table 1, exhaust pipes 3 are fixedly connected to the left and right ends of the processing table 1, support rods 4 are fixedly connected to the left and right sides of the top of the processing table 1, a processing component is arranged on the left side of the top of the processing table 1, and an exhaust component is arranged on the inner wall of the bottom end of the processing table 1, a clamping frame 5 is fixedly connected to the upper side of the opposite end of the support rod 4, and the inner walls of the front and rear ends of the clamping frame 5 are rotatably connected to the bidirectional screws 15 and It runs through the front and back sides, and the threads on both sides of the outer wall of the two-way screw 15 are in opposite directions. The front and back sides of the outer wall of the two-way screw 15 are threadedly connected with sliders 14. The opposite ends of the left and right sliders 14 are slidably connected to the inner wall of the clamping frame 5. The top of the slider 14 is fixed with a clamping plate 6. Two sections of angle steel of the same size are placed between the clamping plates 6 on both sides, so that the opposite ends of the angle steels are against each other, and then the two-way screws 15 on both sides are rotated respectively, so that the sliders 14 are threadedly slid in opposite directions on the outer wall of the two-way screw 15, thereby driving the clamping plate 6 to clamp the angle steel.

[0033] Specifically, the processing assembly includes a motor 7, the bottom end of the motor 7 is installed on the right side of the top of the processing table 1 near the left support rod 4, the driving end of the motor 7 is fixedly connected to a gear 8, the top of the outer diameter of the gear 8 is meshed with a gear ring 12, the right end of the gear ring 12 is fixedly connected to a through groove ring 10, and a telescopic cylinder 16 is installed on the inner wall of the bottom end of the through groove ring 10, and the driving end of the telescopic cylinder 16 is fixedly connected to a welding gun 17. The telescopic cylinder 16 is started to push the welding gun 17 to the position of the angle steel, and the right end of the through groove ring 10 is rotatably connected to a connecting ring 11, and the bottom end of the connecting ring 11 is fixedly connected to a fixing column 9, and the bottom end of the fixing column 9 is fixedly connected to the top of the processing table 1. The motor 7 is started to drive the gear 8 to rotate through the driving shaft, and the gear ring 12 is rotated under the transmission action of the gear 8, thereby driving the through groove ring 10 to rotate. While the through groove ring 10 rotates, the welding gun 17 welds the angle steels that are against each other, thereby maintaining the continuity of the welding seam. The welding gun 17 used in the present invention is a tool that can be used for an automated welding process.

[0034] Specifically, the exhaust assembly includes an exhaust pump 19, the bottom end of which is mounted on the inner wall of the middle part of the rear side of the bottom end of the processing table 1, and the driving end of the exhaust pump 19 is fixedly connected to a connecting pipe 20, the other end of the connecting pipe 20 passes through the rear end of the processing table 1, and an exhaust hood 21 is fixedly connected to the upper side of the front end of the connecting pipe 20. When the exhaust pump 19 is started, the exhaust hood 21 sucks in the exhaust gas generated during the welding process and discharges it into the processing table 1 through the connecting pipe 20. The inner wall of the processing table 1 is fixedly connected with a slide frame 18 on both upper and lower sides corresponding to the slot opening 2, and the upper and lower slide frames 18 are embedded with activated carbon plates 13 at opposite ends. The exhaust gas passes through the activated carbon plates 13 on both sides of the processing table 1. At the same time, due to the material characteristics of the activated carbon plates 13, harmful gases in the exhaust gas will be adsorbed, and the filtered gas will be discharged outward along the exhaust pipe 3. The shape of the front end of the activated carbon plate 13 is consistent with the shape of the inner wall of the slot opening 2. Afterwards, the activated carbon plate 13 only needs to be pulled out of the slide frame 18 through the slot opening 2 to be replaced.

[0035] Working principle: First, place two sections of angle steel of the same size between the two side clamps 6, so that the opposite ends of the angle steels are against each other, and then rotate the two-way screws 15 on both sides respectively, so that the slider 14 slides in the opposite direction on the outer wall of the two-way screw 15, thereby driving the clamp 6 to clamp the angle steel, and then start the telescopic cylinder 16 to push the welding gun 17 to the position of the angle steel, and then start the motor 7 to drive the gear 8 to rotate through the drive shaft, and under the transmission action of the gear 8, the gear ring 12 rotates, and then drives the groove ring 10 to rotate. At the same time, the welding gun 17 welds the abutting angle steels to maintain the continuity of the welding seam. At the same time, the vacuum pump 19 is started, so that the vacuum hood 21 sucks the exhaust gas generated in the welding process and discharges it into the processing table 1 through the connecting pipe 20. Then the exhaust gas passes through the activated carbon plates 13 on both sides of the processing table 1. At the same time, due to the material characteristics of the activated carbon plates 13, the harmful gases in the exhaust gas will be absorbed, and the filtered gas will be discharged outward along the exhaust pipe 3. After that, the activated carbon plate 13 only needs to be pulled out from the slide frame 18 through the slot opening 2 to be replaced.
