Description

Technical Field

[0001] This utility model belongs to the field of welding protection technology, specifically a protective base for welding protection. Background Technology

[0002] When assembling the sheet metal, it needs to be welded. The existing welding method is to place the sheet metal on a base and braze it.

[0003] Brazing is a method in which a filler metal with a lower melting point than the base metal and the workpiece are heated together, so that the filler metal melts (while the workpiece does not melt), and then wets and fills the gap between the base metals. The filler metal and the base metal diffuse into each other to form a strong connection.

[0004] The brazing process generates intense light, and workers can wear protective goggles to work. However, because the base does not provide any shielding, people in the vicinity are easily injured by the intense light due to the lack of protective goggles. Utility Model Content

[0005] This utility model provides a protective base for welding protection, which solves the defects in the prior art.

[0006] This utility model is achieved through the following technical solution:

[0007] A protective base for welding protection includes a base plate and a U-shaped plate fixedly mounted along the edge of the base plate. A blind hole is provided on the base plate, and a rotating shaft is provided in the blind hole. The rotating shaft and the blind hole are rotatably connected by a damping bearing. A rotating plate is vertically connected to the upper end of the rotating plate. A groove is provided on the top surface of the rotating plate, and an electromagnet is fixedly mounted in the groove. The top surface of the electromagnet and the top surface of the rotating plate are located on the same horizontal plane.

[0008] In use, the plates to be welded are placed on a rotating plate. The worker operates at the C-shaped opening of the plate, while the other three directions are shielded by the C-shaped plate, effectively preventing other personnel from being harmed by strong light. When welding is completed on one side and welding is needed in other directions, rotating the plate moves the plate, allowing welding to be performed in those areas. Since the plates are mostly made of iron, they are easily attracted. An electromagnet is energized during welding, generating magnetism to ensure the plates adhere to the rotating plate. The electromagnet is de-energized when moving the plates, facilitating removal.

[0009] Preferably, the base plate has a receiving groove, one side of which extends through the base plate. A receiving drawer is located within the receiving groove. A through groove is formed on the top surface of the base plate, communicating downwards with the receiving groove and being vertically opposite to the receiving drawer. Welding slag can be pushed into the through groove and then fall into the receiving drawer, achieving unified collection and treatment of the slag and preventing its accumulation on the base plate and rotating plate.

[0010] Preferably, the through groove is an arc-shaped structure located on the same circle, and the diameter of the circle containing the through groove is at the same center as the rotation trajectory of the rotating plate. The arc-shaped structure of the through groove allows the welding slag on the rotating plate to fall quickly into the through groove when pushed onto the base plate.

[0011] Preferably, the bottom surface of the rotating plate has a ball bearing cavity, which is evenly arranged along the circumference of the rotating plate's rotation trajectory line, and ball bearings are fitted inside the ball bearing cavity. The ball bearings not only provide support, but also change the friction between the rotating plate and the base plate from sliding friction to rolling friction, thereby reducing friction.

[0012] Preferably, the top edge of the rotating plate is a tapered surface that slopes outward from top to bottom, which facilitates the removal of welding slag from the rotating plate.

[0013] Preferably, the groove is an annular groove and multiple grooves are provided on the rotating plate. The multiple grooves have different diameters and are concentric. The electromagnet is an annular structure corresponding to the groove, which can easily attract plates of different sizes and increase the applicability.

[0014] The beneficial effects of this utility model are as follows: The use of this application can not only block the other three directions during welding by using the C-shaped plate to prevent others from being harmed by strong light, but also allow the plate to be rotated by rotating the rotating plate after welding one side, ensuring that the direction to be welded is always facing the worker, which is convenient for the worker to weld.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] A protective base for welding protection, such as Figures 1-3 As shown. It includes a base plate 1 and a U-shaped plate fixedly mounted along the edge of the base plate 1. A blind hole is formed in the base plate 1, and a rotating shaft 6 is installed within the blind hole. The rotating shaft 6 is rotatably connected to the blind hole via a damping bearing. A rotating plate 4 is vertically connected to the upper end of the rotating plate. A groove 3 is formed on the top surface of the rotating plate 4, and an electromagnet 5 is fixedly installed within the groove 3. The top surface of the electromagnet 5 and the top surface of the rotating plate 4 are located on the same horizontal plane. The groove 3 is an annular groove, and multiple grooves 3 are provided on the rotating plate 4. The multiple grooves 3 have different diameters and are concentric. The electromagnet 5 is an annular structure corresponding to the groove 3. A lever is provided on the rotating plate 4 to facilitate its rotation.

[0023] In use, the sheet material to be welded is placed on a rotating plate 4. The worker operates at the opening of the U-shaped plate 2, while the other three directions are shielded by the U-shaped plate 2, effectively preventing other personnel from being harmed by strong light. When welding is completed on one side and welding is needed in other directions, rotating the rotating plate 4 moves the sheet material, allowing welding to be performed in those directions. Since the sheet material is mostly made of iron, it can be attracted. Therefore, the electromagnet 5 is energized during welding, generating magnetism to ensure the sheet material adheres to the rotating plate 4. The electromagnet is de-energized when moving the sheet material for easy removal. Multiple grooves 3 are provided to easily hold sheet materials of different sizes, increasing its applicability. Damping bearings ensure that the rotating plate 4 does not rotate arbitrarily, thus facilitating welding.

[0024] The base plate 1 has a receiving groove 9, one side of which penetrates the base plate 1. A receiving drawer 7 is located within the receiving groove 9. A through groove 8 is formed on the top surface of the base plate 1, communicating downwards with the receiving groove 9 and being vertically opposite to the receiving drawer 7. Welding slag generated during welding can be pushed into the through groove 8 and then fall into the receiving drawer 7, achieving unified collection and treatment of the welding slag and preventing its accumulation on the base plate 1 and the rotating plate 4.

[0025] The through groove 8 is an arc-shaped structure located on the same circle, and the diameter of the circle containing the through groove 8 is at the same center as the rotation trajectory of the rotating plate 4. The arc-shaped structure of the through groove 8 allows the welding slag on the rotating plate 4 to be pushed onto the base plate 1 and quickly fall into the through groove 8.

[0026] The bottom surface of the rotating plate 4 is provided with a ball bearing cavity 10, which is evenly arranged along the circumference of the rotation trajectory line of the rotating plate 4. The ball bearing 10 is fitted inside the ball bearing cavity 10. The ball bearing 10 not only provides support, but also changes the friction between the rotating plate 4 and the base plate 1 from sliding friction to rolling friction, thereby reducing friction.

[0027] The top edge of the rotating plate 4 is a tapered surface 11 that slopes outward from top to bottom, which facilitates the removal of welding slag from the rotating plate 4.

[0028] The use of this application can not only block the other three directions during welding by using the C-shaped plate 2 to prevent others from being harmed by strong light, but also allow the plate to be rotated by rotating the rotating plate 4 after welding one side, ensuring that the direction to be welded is always facing the worker, making it convenient for the worker to weld.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
