Description

Technical Field

[0001] This application relates to the technical field of steel component welding, and particularly to a fixing tooling for steel component welding. Background Art

[0002] Steel components refer to steel structure composite components that can bear and transfer loads, which are formed by connecting steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams through cold bending or welding with connectors.

[0003] However, in actual applications, when most existing steel components are welded pairwise, it is necessary to ensure that the welded sides of the two steel components are always in contact during the welding process. However, the high temperature generated during the welding process will generate inward stress, making the two steel components prone to varying degrees of bending deformation towards the welding surface, which will reduce the welding quality and increase the defective rate.

[0004] Therefore, those skilled in the art have provided a fixing tooling for steel component welding to solve the problems raised in the above background art. Utility Model Content

[0005] In order to solve the problem that the high temperature generated during the welding process in the above background art will generate inward stress, making the two steel components prone to varying degrees of bending deformation towards the welding surface, which will reduce the welding quality and increase the defective rate, this application provides a fixing tooling for steel component welding.

[0006] The fixing tooling for steel component welding provided by this application adopts the following technical solutions: It includes a base, and three supporting platforms are installed on the top side of the base. Two L-shaped clamping plates are installed on the top side of each of the three supporting platforms. Screws are threadedly connected to the top sides of the six L-shaped clamping plates. The bottom ends of four of the screws are rotatably connected to pressing plates. Anti-slip pads are fixedly connected to the bottom sides of the six pressing plates. One of the three supporting platforms is fixedly connected to the center of the top side of the base.

[0007] Preferably, a bidirectional lead screw is rotatably connected to the front side of each of the three supporting platforms, and the six L-shaped clamping plates are respectively in screw drive connection with the three bidirectional lead screws.

[0008] Preferably, two sliding grooves are opened on the top side of the base, and sliders are slidably connected to the inner walls of the two sliding grooves. The two sliders are fixedly connected to the bottom sides of two of the three supporting platforms.

[0009] Preferably, hexagonal drive blocks are fixedly connected to the top ends of the six screws and the front ends of the two bidirectional lead screws.

[0010] Preferably, the six L-shaped clamping plates are respectively in contact with the inner walls of the three sides of the three supporting platforms.

[0011] In summary, the present application includes the following beneficial technical effects:

[0012] 1. By providing a pressure plate, two steel members to be welded are horizontally placed on the support table, and the sides to be welded of the two steel members are brought into contact. Then, the screws are respectively turned. When the screws rotate and move downward, they will synchronously drive the pressure plate to move downward until it contacts the surface of the steel member and squeezes and fixes it. Thereby, it is possible to prevent the two steel members from bending and deforming due to the internal stress during welding, effectively ensuring the welding quality of the steel members and reducing the defective rate.

[0013] 2. By providing a bidirectional lead screw, when the bidirectional lead screw is turned, the two L-shaped clamping plates can be driven to approach each other simultaneously when the bidirectional lead screw rotates, thereby squeezing the two placed steel members and further improving the stability during welding and ensuring the welding quality.

Then, the screws 4 are respectively rotated. When the screws 4 rotate and move downward, they will synchronously drive the pressing plates 5 to move downward. The pressing plates 5 move downward until they contact the surface of the steel members and perform extrusion fixation, so that the two steel members can be prevented from bending and deforming due to the internal stress during welding, effectively ensuring the welding quality of the steel members and reducing the defective rate.

[0021] In the present application, a bidirectional lead screw 7 is rotatably connected to the front side of each of the three supporting platforms 2.

[0023] In this application, hexagonal drive blocks 9 are fixedly connected to the tops of the six screws 4 and the front ends of the two double lead screws 7. By providing the hexagonal drive blocks 9, when the screws 4 and the double lead screws 7 are turned, the hexagonal drive blocks 9 can facilitate the operation of workers using tools, improving the convenience during operation while saving effort.

[0024] In this application, six L-shaped clamping plates 3 are respectively attached to the inner walls of three sides of the three supporting platforms 2. By providing that the six L-shaped clamping plates 3 are respectively attached to the inner walls of three sides of the three supporting platforms 2, the L-shaped clamping plates 3 can be limited during movement, ensuring that the L-shaped clamping plates 3 move horizontally while avoiding deviation.

Then, turn the screw rods 4 respectively. When the screw rods 4 rotate and move downward, they will synchronously drive the pressure plates 5 to move downward.

Turn the bidirectional lead screw 7. When the bidirectional lead screw 7 rotates, it can drive the two L-shaped clamping plates 3 to approach each other simultaneously, thereby squeezing the two placed steel members and further improving the stability during welding to ensure the welding quality.

When turning the screw rods 4 and the bidirectional lead screw 7, the hexagonal transmission blocks 9 can facilitate the operation of workers using tools, improving the convenience during operation on the premise of saving effort. The six L-shaped clamping plates 3 are respectively attached to the inner walls of three sides of the three support tables 2, so that the L-shaped clamping plates 3 can be limited during movement, ensuring that the L-shaped clamping plates 3 move horizontally while avoiding deviation.
