Technical Field
[0001] The utility model belongs to the technical field of steel column welding equipment, and particularly relates to a steel column welding equipment for preventing deformation. Background Technique
[0002] The steel column welding equipment is a kind of welding equipment specially used for welding metal studs or similar parts. The stud welder uses instantaneous pressurization and discharging to weld the entire end face of the stud to the workpiece to form a metal recrystallization connection. However, when the existing steel column welding equipment welds a steel column, since the welding range of the steel column is a circle, it is necessary to frequently adjust the angle of the steel column for welding, resulting in discontinuous welding points. Local deformation is likely to occur during repair welding, wasting time and reducing the welding quality. Content of the Utility Model
[0003] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide a steel column welding equipment for preventing deformation, which has the advantages of automatic adjustment and continuous welding, and solves the problem that when the existing steel column welding equipment welds a steel column, since the welding range of the steel column is a circle, it is necessary to frequently adjust the angle of the steel column for welding, resulting in discontinuous welding points. Local deformation is likely to occur during repair welding, wasting time and reducing the welding quality.
[0004] The present utility model provides the following technical solution: a steel column welding equipment for preventing deformation, including a workbench. Both sides of the top of the workbench are provided with motor seats. Stepping motors are fixedly connected to the tops of the motor seats. Output ends of the stepping motors are fixedly connected with turntables. Clamping seats are fixedly connected to the inner sides of the turntables. Clamping grooves are formed on the inner surfaces of the clamping seats. The top walls of the clamping grooves are rotatably connected with first double threaded rods through bearings. Slide plates are threadedly connected to both sides of the surfaces of the first double threaded rods. The slide plates are slidably connected to the clamping grooves. Clamping plates are fixedly connected to the inner sides of the slide plates. Clamping motors are fixedly connected to the bottoms of the clamping seats. Output ends of the clamping motors penetrate into the interiors of the clamping seats and are fixedly connected with the first double threaded rods. A vertical plate is arranged at the rear side of the workbench. A connecting arm is fixedly connected to the front surface of the vertical plate. A welding head is arranged at the front end of the connecting arm.
[0005] The beneficial effects of the present utility model are as follows:
[0006] 1. Through the setting of the stepping motor, first place two steel columns on the inner side of the clamping plate in sequence. At the same time, start the clamping motor successively to make the first double threaded rod rotate. The first double threaded rod drives the sliding blocks on both sides of its surface to move relatively, so that the clamping plate moves relatively to clamp the steel column tightly. Then, the welding head can be started for welding. When the welding angle needs to be adjusted, two stepping motors can be started synchronously to make the turntable drive the clamping seat to rotate. The clamping seat will drive the two steel columns to rotate automatically and synchronously for one week, making the welding points coherent and avoiding local deformation caused by repair welding, greatly improving the welding efficiency and quality.
[0007] 2. Through the setting of the second double threaded rod, start the adjusting motor to make the second double threaded rod drive the adjusting blocks on both sides of its surface to move relatively, so that the distance between the clamping plates can be extended or shortened, and then various lengths of steel columns can be clamped for welding, greatly improving the applicability of the equipment.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0014] Such as Figures 1 to 5As shown in the figure, the anti-deformation steel column welding equipment of this embodiment includes a workbench 1. On both sides of the top of the workbench 1, there are motor seats 2. On the top of the motor seats 2, stepping motors 3 are fixedly connected. The output ends of the stepping motors 3 are fixedly connected with turntables 4. Inside the turntables 4, clamping seats 5 are fixedly connected. On the inner surface of the clamping seats 5, clamping grooves 6 are opened. The top walls of the clamping grooves 6 are rotatably connected with first double threaded rods 7 through bearings. On both sides of the surface of the first double threaded rods 7, sliding plates 8 are threadedly connected. The sliding plates 8 are all slidably connected with the clamping grooves 6. On the inner sides of the sliding plates 8, clamping plates 9 are fixedly connected. At the bottom of the clamping seats 5, clamping motors 10 are fixedly connected. The output ends of the clamping motors 10 all penetrate into the interior of the clamping seats 5 and are fixedly connected with the first double threaded rods 7. At the rear of the workbench 1, there is a vertical plate 11. On the front of the vertical plate 11, a connecting arm 12 is fixedly connected. At the front end of the connecting arm 12, there is a welding head 13.
[0015] Reference Figure 1 and Figure 2 , on the right side of the workbench 1, an adjusting motor 14 is fixedly connected. On both sides of the surface of the workbench 1, adjusting grooves 15 are opened. The output end of the adjusting motor 14 penetrates into the interior of the adjusting groove 15 and is fixedly connected with a second double threaded rod 16. The second double threaded rod 16 penetrates through the workbench 1 and extends into the adjusting groove 15 on the left side. The left end of the second double threaded rod 16 is rotatably connected with the left wall of the adjusting groove 15 through a bearing. Inside the adjusting grooves 15, adjusting blocks 17 are slidably connected. The adjusting blocks 17 are all sleeved on both ends of the second double threaded rod 16 and are threadedly connected with it. The tops of the adjusting blocks 17 are all fixedly connected with the motor seats 2.
[0016] In this embodiment, through the setting of the second double threaded rod 16, starting the adjusting motor 14 causes the second double threaded rod 16 to drive the adjusting blocks 17 on both sides of its surface to move relatively, so that the distance between the clamping plates 9 can be extended or shortened, and thus various lengths of steel columns can be clamped for welding, greatly improving the applicability of the equipment.
[0017] Reference Figure 1 , Figure 2 and Figure 5 , on the inner surface of the clamping plates 9, V-shaped grooves 18 are opened. On the inner surface of the clamping plates 9, anti-slip pads 19 are fixedly connected. The anti-slip pads 19 all extend into the V-shaped grooves 18 and are fixedly connected with them. Anti-slip patterns are provided on the surfaces of the anti-slip pads 19.
[0018] In this embodiment, through the setting of the V-shaped grooves 18, the stress points between the clamping plates 9 and the steel column are increased. At the same time, the anti-slip pads 19 increase the friction with the steel column, making the clamping plates 9 clamp the steel column more firmly and not easy to slide.
[0019] Reference Figure 1 , Figure 2 and Figure 4, on both sides of the surface of the workbench 1, there are fixed connections with supports 20. The supports 20 are located inside the clamping plates 9. On the surfaces of the supports 20, arc-shaped grooves 21 are provided, and inside the arc-shaped grooves 21, there are fixed connections with first semi-circular bearings 22.
[0020] In this embodiment, through the setting of the supports 20, support can be provided for relatively long steel columns, avoiding the problem that they may have slight bending due to their length, resulting in difficulty in aligning the cross-sections of the steel columns, and thus causing deformation during welding. At the same time, the first semi-circular bearings 22 facilitate the rotation of the steel columns, further enhancing the practicality of the device.
[0021] Reference Figure 1 , Figure 2 and Figure 4 , on both sides of the top of the supports 20, there are fixed connections with electric push rods 23. On the tops of the electric push rods 23, there are fixed connections with pressing plates 24. On the bottoms of the pressing plates 24, there are fixed connections with second semi-circular bearings 25.
[0022] In this embodiment, through the setting of the electric push rods 23, starting the electric push rods 23 causes the pressing plates 24 to drive the second semi-circular bearings 25 to descend to limit and fix the steel columns, avoiding the situation that the steel columns slide back and forth during welding, resulting in welding deformation.
[0023] Reference Figures 1 to 3 , on the back of the workbench 1, there is a fixed connection with a connecting seat 26. On the surface of the connecting seat 26, there is a moving groove 27. The vertical plate 11 is slidably connected to the moving groove 27. The front wall of the moving groove 27 is rotatably connected to a lead screw 28 through a bearing. On the side of the vertical plate 11, there is an internal thread hole 29. The vertical plate 11 is sleeved on the surface of the lead screw 28 through the internal thread hole 29 and is threadedly connected thereto. The rear end of the lead screw 28 penetrates to the rear side of the connecting seat 26 and is fixedly connected to a turning handle 30.
[0024] In this embodiment, through the setting of the lead screw 28, the turning handle 30 can be rotated to make the lead screw 28 rotate. The lead screw 28 drives the vertical plate 11 to slide on its surface, so that the distance between the welding head 13 and the surface of the steel column can be adjusted according to the diameters of different steel columns, further enhancing the applicability of the device.
[0025] For the present utility model, the adjusting motor 14 can be started first according to the length of the steel column, so that the second double threaded rod 16 drives the adjusting blocks 17 on both sides of its surface to move relatively, thereby extending or shortening the distance between the clamping plates 9. Then, the two steel columns are sequentially placed inside the clamping plates 9, and the outer ends of the steel columns are fitted with the clamping seats 5, and the inner ends of the steel columns are placed on the top of the first semi-circular bearings 22. At the same time, the clamping motor 10 is started in sequence to make the first double threaded rod 7 rotate. The first double threaded rod 7 drives the sliding plates 8 on both sides of its surface to move relatively, and further makes the clamping plates 9 move relatively to clamp the steel column tightly. Then, the electric push rod 23 is started to make the pressing plate 24 drive the second semi-circular bearing 25 to descend to limit and fix the inner end of the steel column. Then, the adjusting motor 14 is started again to make the adjusting blocks 17 move relatively, so that the inner end faces of the two steel columns are fitted together for convenient welding. Then, the handle 30 can be rotated to make the lead screw 28 rotate. The lead screw 28 drives the vertical plate 11 to slide on its surface, so that the welding head 13 contacts the welding end of the steel column for welding. Finally, the two stepping motors 3 are started synchronously to make the turntable 4 drive the clamping seat 5 to rotate. The clamping seat 5 will drive the two steel columns to rotate automatically and synchronously for one week to complete the welding.
