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.

[0031] Example 1: Automatic welding device for epoxy zinc-based composite columns, see Figure 1-Figure 5As shown, it includes a base 1, a workbench 2, a servo motor 3, a turntable 4, a welding gun 5 and a clamping assembly. The workbench 2 is installed on the top of the base 1 by bolt connection. The middle of the top of the workbench 2 is a protruding square frame, which is convenient for blocking and limiting the sparks generated by welding to prevent the spark particles from splashing. A turntable 4 for placing a column is rotatably arranged in the middle of the top of the workbench 2. The servo motor 3 is embedded on the base 1. The output shaft of the servo motor 3 penetrates the workbench 2 and is fixedly connected to the turntable 4 by a key. The turntable 4 can be driven to rotate by starting the servo motor 3. A welding gun 5 is placed on the right side of the top of the workbench 2. A clamping assembly for clamping the column to prevent the column from tipping over is provided on the workbench 2. It also includes a cover plate 10, a connecting rod 1001, a support seat 11, a guide rod 12, a contact plate 13, and an elastic member 14. and a push rod 15. Support seats 11 are installed on the left and right sides of the base 1. A guide rod 12 is slidably arranged on the support seat 11. The ends of the two guide rods 12 that are close to each other are fixedly connected with a contact plate 13 by welding. The other ends of the two guide rods 12 are fixedly connected with two symmetrical connecting rods 1001 by welding. The upper parts of the two connecting rods 1001 are fixedly connected with a cover plate 10 by welding. The cover plate 10 is slidably connected to the workbench 2. A push rod 15 is slidably arranged on the front side of the top of the base 1. The push rod 15 is roughly an isosceles triangle, which is convenient for pushing the contact plates 13 on both sides smoothly at the same time. Elastic members 14 for pushing the contact plates 13 on both sides to slide and reset to the middle are wound around the two guide rods 12. The two contact plates 13 are pushed open to both sides by pushing the push rod 15 inward.

[0032] See also Figure 2 and Figure 3 As shown, the clamping assembly includes a support frame 6, a guide rod 7, a clamping plate 8 and an elastic member 9. Two left-right symmetrical support frames 6 are installed on the workbench 2 by bolt connection. Two guide rods 7 are slidably arranged on the support frame 6. The same end of the two guide rods 7 is fixedly connected with a clamping plate 8 by welding. The guide rods 7 drive the clamping plate 8 to slide horizontally on the support frame 6. The two clamping plates 8 are located on the side where the guide rods 7 on both sides are close to each other. Each guide rod 7 is wound with an elastic member 9 for pushing the clamping plate 8 to slide toward the middle to clamp the column.

[0033] When the epoxy zinc-based composite column is to be welded, the contact plates 13 on both sides are moved away from each other by pushing the push rod 15, and the contact plates 13 on both sides slide in opposite directions through the guide rod 12. At this time, the elastic members 14 on both sides are compressed, and the guide rod 12 drives the cover plate 10 to move away from each other through the connecting rod 1001, so that the working area of ​​the workbench 2 is exposed, and then the chassis is placed on the turntable 4, and the splints 8 on both sides are pulled apart in opposite directions along the guide rod 17. At this time, the elastic member 19 is compressed and deformed, and then the column is placed between the two splints 8. After the splints 8 are released, the elastic member 9 loses the force and returns to its original state, thereby pushing the splints 8 on both sides to slide back to the middle to clamp the column, and then releasing the push rod. Rod 15, the elastic parts 14 on both sides lose the force and return to their original state, thereby pushing the guide rods 12 and the contact plates 13 on both sides to slide toward the middle, and the two contact plates 13 jointly push the push rod 15, so that the push rod 15 slides forward and resets, and the reset of the guide rod 12 drives the connecting rod 1001 and the cover plate 10 fixedly connected thereto to reset, and the two cover plates 10 block the working area of ​​the workbench 2, and then start the welding gun 5 and the servo motor 3, and the welding gun 5 welds the connection between the chassis and the column, and the servo motor 3 drives the turntable 4 to rotate, and the turntable 4 drives the chassis and the column that have been partially welded to rotate, so that the unwelded part is turned to the position of the welding gun 5, so that the welding gun 5 completely welds the chassis and the column.

[0034] Example 2: Based on Example 1, refer to Figure 6 As shown, it also includes a guide rod three 16, a limit seat 17 and an elastic member three 18. The workbench 2 is located on one side of the welding gun 5 and is fixedly connected with two guide rods three 16 by means of bolts. The limit seats 17 are slidably arranged on the two guide rods three 16. The limit seats 17 are fixedly connected to the welding gun 5 by means of bolts. The limit seats 17 drive the welding gun 5 to slide horizontally left and right on the two guide rods three 16. An elastic member three 18 is wound around the guide rod three 16 for pushing the limit seat 17 against the column.

[0035] According to the different sizes of the columns, the limit seat 17 is pressed against the side of the column, so that the limit seat 17 drives the welding gun 5 to slide along the guide rod three 16, and the elastic member three 18 always keeps pushing the limit seat 17 against the side of the column, so that the welding gun 5 can be adjusted to the welding position to weld the connection between the column and the chassis.

[0036] See also Figure 6As shown, it also includes a fixed seat 19, a support rod 20, a drive motor 2001 and a grinding wheel 21. The fixed seat 19 is installed on the upper rear side of the workbench 2 by means of bolts. The support rod 20 is fixedly connected to the fixed seat 19 by means of welding. The drive motor 2001 is installed on the top of the side of the support rod 20 close to the turntable 4 by means of bolts. The output shaft of the drive motor 2001 faces downward, and the output shaft of the drive motor 2001 is fixedly connected to the grinding wheel 21 by a key. The grinding wheel 21 is driven to rotate by the drive motor 2001.

[0037] When welding columns, due to uncontrollable factors, granular bumps are often formed at the welding points. During welding, the driving motor 2001 is started to drive the grinding wheel 21 to rotate, and the grinding wheel 21 grinds the bump particles to make the welding point more beautiful.

[0038] See also Figure 7 and Figure 8 As shown, it also includes a fixing frame 23, a connecting seat 2301, a fan 24, a filter element 2401, an air guide pipe 25 and a suction nozzle 26. Two symmetrical fixing frames 23 are installed on the top of the two connecting rods 1001 by bolts. The connecting seats 2301 for supporting the fixing frames 23 are installed on the two cover plates 10 by bolts. The connecting seat 2301 is fixedly connected to the fixing frame 23 by bolts. The fan 24 is installed on the upper part of the fixing frame 23 by bolts. The two fans 24 are close to each other. One side is connected and communicated with an air duct 25, and the other end of the air duct 25 is connected and communicated with a suction nozzle 26. The side of the suction nozzle 26 is fixedly connected to the fixing frame 23 by means of bolts. The two suction nozzles 26 are both semi-annular and surround the edge of the circular hole in the middle of the two cover plates 10 to facilitate the absorption of the generated harmful smoke. A plurality of filter elements 2401 are evenly spaced and embedded on the top of the fan 24. The smoke is sucked in from the suction nozzle 26 through the air duct 25 by the fan 24, and the smoke is filtered and discharged through the filter element 2401.

[0039] When welding, harmful smoke is easily generated. At this time, by starting the fan 24, the generated harmful smoke is sucked in through the suction nozzle 26, and the harmful smoke is sucked into the fan 24 through the air duct 25. The fan 24 filters the harmful smoke through the filter element 2401 and then discharges it. When the connecting rod 1001 and the cover plate 10 move, the fixing frame 23 will be driven to move, and then the fan 24 and the suction nozzle 26 will move together.
