Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel welding technology, and in particular relates to a clamp for steel welding. Background Technology
[0002] Square steel refers to steel ingots, billets, or steel products that are processed under pressure to produce various shapes, sizes, and properties as required. Steel is an essential material for national construction and the realization of modernization, with wide applications and numerous varieties.
[0003] Most steel welding methods have some drawbacks. For example, square steel bars need to be welded into T- or L-shapes, and most clamps can only fix two square steel bars in one way, failing to meet the clamping requirements for both welding methods, resulting in insufficient applicability of the overall device. Therefore, we propose a clamp for steel welding. Utility Model Content
[0004] The purpose of this invention is to provide a fixture for welding steel, so as to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a clamp for welding steel, including a base, and further comprising: Two fixing bars are fixedly installed on the top of the base. The base has a sliding groove, and a sliding plate is slidably installed in the sliding groove. Two guide grooves are opened on the sliding plate, and guide posts are slidably installed in each of the two guide grooves. A fixing post is fixedly installed at the top of each of the two guide posts. The upper end of each of the two fixing posts passes through the sliding groove and is fixedly installed with a fixing block. Both fixing posts are slidably connected to the sliding groove. A power chamber is formed inside the base. A sliding strip is slidably installed inside the power chamber. The top of the sliding strip passes through the power chamber and is fixedly installed with a limit strip. A rectangular plate is slidably installed inside the limit strip. A drive assembly, located within the base, is used to drive the sliding plate to slide. A power assembly, located within the base, is used to drive the sliding bar and the rectangular plate to slide.
[0006] In this technical solution, when welding T-shaped square steel bars, one square steel bar is first placed between two fixed bars and a limiting bar. A power component drives a sliding bar to slide towards the fixed bars, which in turn drives the limiting bar to slide towards the fixed bars. The limiting bar and the two fixed bars fix the position of one square steel bar. Then, another square steel bar is placed between two fixed blocks, bringing the two steel bars into contact. A drive component drives a sliding plate to slide, which in turn drives two guide posts through two guide grooves. The guide posts then drive two fixed posts to slide and move closer together. The fixed posts then drive two fixed blocks to slide and move closer together. The two fixed blocks fix the position of the other square steel bar, facilitating welding. After the tops and sides of the two square steel bars are welded together, their positions are fixed. Then, the two square steel bars are removed, and their bottoms are welded together. The finished product is a T-shape. When welding L-shaped square steel bars, the set power component can push the rectangular plate to slide towards the fixing bar. Then the rectangular plate extends out of the limiting bar. When the rectangular plate slides to the appropriate position, the position of the rectangular plate can be fixed. Then, one of the square steel bars is placed between the fixing bar and the limiting bar, and one end of the steel bar is in close contact with the rectangular plate, which can fix the position of the steel bar. Then, the position of the other square steel bar is fixed by the above operation, and the two square steel bars are in close contact, which can weld L-shaped square steel bars. This expands the application range of the overall device, and the welding slag produced during welding will not fall into the base. The welding slag will only stay on the top of the base, which is convenient for the staff to clean.
[0007] In the above technical solution, the driving component further includes: A first motor is fixedly installed in the sliding groove and located on one side of the sliding plate. The output shaft of the first motor is fixedly installed with a threaded rod. One end of the threaded rod passes through the sliding plate and is threadedly connected to the sliding plate.
[0008] In this technical solution, the first motor is started, and the first motor is powered on and drives the threaded rod to rotate. Under the action of the thread, the threaded rod drives the sliding plate to slide. The sliding plate drives the two guide posts to slide through the two guide grooves. The two guide posts drive the two fixed posts to slide and move closer to each other. The two fixed posts drive the two fixed blocks to slide and move closer to each other. The two fixed blocks can fix the position of the other square steel.
[0009] In the above technical solution, the power component further includes: The second motor is fixedly installed inside the power cavity and located on one side of the sliding bar. A gear is fixedly installed on the output shaft of the second motor, and a rack is fixedly installed on the sliding bar and located on one side of the gear. The rack meshes with the gear. A limiting rod is slidably installed inside the limiting strip and located at the top of the rectangular plate. The lower end of the limiting rod extends into the rectangular plate and is inserted into the rectangular plate. Two tension springs that are fixed to the top of the limiting strip are fixedly installed on the limiting rod.
[0010] In this technical solution, one of the square steel bars is first placed between the two fixed bars and the limiting bar. Then, the second motor is started. The second motor is powered on and drives the gear to rotate. The gear drives the rack meshing with it to slide towards the fixed bar. The rack drives the sliding bar to slide towards the fixed bar. The sliding bar drives the limiting bar to slide towards the fixed bar. The limiting bar and the two fixed bars will fix the position of one of the square steel bars. When welding L-shaped square steel bars, first pull the limiting rod upwards, while the two tension springs are stretched. After the lower end of the limiting rod disengages from the rectangular plate, it pushes the rectangular plate towards the fixing strip. Then, the rectangular plate extends out of the limiting strip. When the rectangular plate slides to the appropriate position, release the limiting rod. Under the tension of the two tension springs, the limiting rod slides downwards and inserts into the rectangular plate, thus fixing the position of the rectangular plate. Then, place one of the square steel bars between the fixing strip and the limiting strip. One end of one of the bars then makes close contact with the rectangular plate, thus fixing the position of one of the square steel bars.
[0011] In the above technical solution, the output shaft and threaded rod of the first motor are rotatably connected to the sliding groove, the rack is slidably connected to the power cavity, and the output shaft and gear of the second motor are rotatably connected to the power cavity.
[0012] In this technical solution, it is ensured that the output shaft and threaded rod of the first motor can rotate in the sliding groove, the rack can slide in the power cavity, and the output shaft and gear of the second motor can rotate in the power cavity.
[0013] In the above technical solution, two guide bars are slidably installed inside the base and at the bottom of the limiting bar. Both guide bars are fixedly connected to the limiting bar, and the cross-section of both guide bars is T-shaped.
[0014] In this technical solution, two guide bars are used to ensure that the two sides of the limit bar can slide stably.
[0015] Furthermore, in the above technical solution, the guide post and the fixing post are integrally formed.
[0016] In this technical solution, both the guide post and the fixed post are ensured to be used stably.
[0017] In the above technical solution, both guide grooves are further arranged at an angle.
[0018] In this technical solution, the sliding plate drives two guide posts to slide through two guide grooves, and the two guide posts drive two fixed posts to slide and move closer to each other.
[0019] In the above technical solution, the diameter of the guide post is adapted to the size of the guide groove.
[0020] In this technical solution, it is ensured that the guide post can slide stably within the guide groove.
[0021] The beneficial effects of this utility model are: 1. This fixture for steel welding places one square steel bar between two fixed bars and a limiting bar. A power component drives a sliding bar and a limiting bar to slide towards the fixed bars, fixing the position of one square steel bar. Then, another square steel bar is placed between two fixed blocks, bringing the two steel bars into contact. A drive component drives a sliding plate, which in turn drives two guide posts through two guide grooves. These guide posts then drive two fixed posts and two fixed blocks to slide closer together, fixing the position of the other square steel bar. This facilitates welding the two steel bars together. After the tops and sides of the two steel bars are welded together, their positions are fixed. The two steel bars can then be removed, and their bottoms welded together. The welded steel bars form a T-shape, automatically fixing their positions.
[0022] 2. This fixture for steel welding, when welding L-shaped square steel, can push a rectangular plate towards a fixing strip via a power component. The rectangular plate then extends out of the limiting strip. When the rectangular plate slides to a suitable position, its position can be fixed. Then, one square steel is placed between the fixing strip and the limiting strip, with one end of the steel in close contact with the rectangular plate, thus fixing its position. The same operation is then used to fix the position of the other square steel, ensuring close contact between the two steels, enabling the welding of L-shaped square steel. This expands the overall applicability of the device and allows for automatic fixing of the positions of the two square steels. Attached Figure Description

[0046] Working principle: When welding T-shaped square steel bars, firstly, one square steel bar is placed between the two fixing bars 2 and the limiting bar 8. Then, the second motor 14 is started, and the second motor 14 is powered on and drives the gear 15 to rotate. The gear 15 drives the rack 16, which meshes with it, to slide towards the fixing bar 2. The rack 16 drives the sliding bar 7 to slide towards the fixing bar 2. The sliding bar 7 drives the limiting bar 8 to slide towards the fixing bar 2. The limiting bar 8 and the two fixing bars 2 will fix the position of one square steel bar. Then, the other square steel bar is placed between the two fixing blocks 5, and the two square steel bars are in contact. Then, the first motor 12 is started. The electric motor drives the threaded rod 13 to rotate. Under the action of the thread, the threaded rod 13 drives the sliding plate 9 to slide. The sliding plate 9 drives the two guide posts 11 to slide through the two guide grooves 10. The two guide posts 11 drive the two fixed posts 4 to slide and move closer to each other. The two fixed posts 4 drive the two fixed blocks 5 to slide and move closer to each other. The two fixed blocks 5 can fix the position of the other square steel, making it convenient for workers to weld the two square steel together. After the top and sides of the two square steel are welded together, the position of the two square steel is fixed. Then, the two square steels can be taken out and their bottoms can be welded together. After the two square steels are welded together, they will form a T-shape. When welding L-shaped square steel, first pull the limiting rod 18 upwards, and at the same time, the two tension springs 19 are stretched. After the lower end of the limiting rod 18 disengages from the rectangular plate 17, push the rectangular plate 17 towards the fixing strip 2. Then the rectangular plate 17 extends out of the limiting strip 8. When the rectangular plate 17 slides to the appropriate position, release the limiting rod 18. Under the pulling force of the two tension springs 19, the limiting rod 18 slides downwards and inserts into the rectangular plate 17, which can fix the position of the rectangular plate 17. Then place one of the square steels between the fixing strip 2 and the limiting strip 8. Then one end of one of the square steels is in close contact with the rectangular plate 17, which can fix the position of one of the square steels. Then, fix the position of the other square steel through the above operation. The two square steels are in close contact, which can weld L-shaped square steel, expanding the application range of the overall device. Moreover, the welding slag produced during welding will not fall into the base 1. The welding slag will only remain on the top of the base 1, which is convenient for the staff to clean.
