Description

Technical fields: This utility model relates to the field of welding technology, specifically to an auxiliary device for welding and repairing disc-shaped metal parts. Background technology: Disc-shaped parts play a crucial role in mechanical equipment, not only improving equipment performance and efficiency but also ensuring its safe operation.

[0001] For disc-shaped parts (such as gear discs, flanges, and brake discs) that experience cracks, wear, or defects during use, welding is generally used for repair. However, the high temperatures generated during welding can easily deform the base material, affecting the dimensional accuracy and shape stability of the part. Therefore, cooling treatment is necessary during welding, typically by pouring water directly onto the weld surface, utilizing the fluidity and high thermal conductivity of water for rapid heat dissipation. Experimental data shows that each weld seam can be cooled to 40°C in just 3 minutes, and this process also refines the grain size and improves mechanical properties.

[0002] The current problems are: because the disc-shaped parts are heavy, they are not easy to rotate during welding, which affects welding efficiency; and when cooling, the water basically flows on the ground, which affects the surrounding environment and wastes water resources. Utility model content: The purpose of this invention is to provide an auxiliary device for welding and repairing disc-shaped metal parts, so as to solve the problems mentioned in the background art.

[0003] This utility model is implemented by the following technical solution: An auxiliary device for welding and repairing disc-shaped metal parts includes a water tank, a support frame, rolling support components, an arc-shaped steel pipe, an arc-shaped round rod, a water pump, and a hose. The support frame is fixed to the top of the water tank. Two sets of rolling support components are symmetrically fixed to both sides of the support frame. An arc-shaped steel pipe and an arc-shaped round rod are connected to the middle of the upper surface of the support frame. One end of the arc-shaped steel pipe is closed, and the other end is a water inlet. Multiple upward-spraying water holes are opened on the arc-shaped steel pipe. The two sets of rolling support components are located between the arc-shaped steel pipe and the arc-shaped round rod. A water pump is placed inside the water tank. The outlet end of the water pump is connected to one end of the hose, and the other end of the hose is connected to the water inlet. Each set of rolling support components includes a first support rod, a second support rod, and a cylindrical ball bearing. One end of both the first and second support rods is fixed to one side of the support frame, and the first and second support rods are vertically aligned. The other ends of both the first and second support rods are fixed with cylindrical ball bearings.

[0004] Preferably, the middle part of the arc-shaped rod is higher than the second support rod.

[0005] Preferably, a support rod is fixed at an angle on the side of the upper surface of the support frame away from the arc-shaped steel pipe, and a thrust cylindrical roller bearing is fixed at the top of the support rod.

[0006] Preferably, a filter plate is fixed in the middle of the water tank, and the filter plate is located between the arc-shaped steel pipe and the arc-shaped round rod.

[0007] The advantages of this utility model are: simple structure, convenient operation, and the ability to help welders quickly rotate disc-shaped parts, thereby improving welding efficiency. At the same time, during the welding and repair process, no external assistance is required for cooling. The cooling water is actively sprayed and cooled by circulating water flow, which enables the management of the cooling water range and avoids the impact on the surrounding environment and the waste of cooling water.

Detailed implementation method: The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0009] Please see Figure 1-5 This utility model provides a technical solution for an auxiliary device for welding and repairing disc-shaped metal parts: An auxiliary device for welding and repairing disc-shaped metal parts includes a water tank 1, a support frame 2, a rolling support assembly 3, an arc-shaped steel pipe 4, an arc-shaped round rod 5, a water pump 6, and a hose 7. A support frame 2 is fixed to the top of the water tank 1, and the support frame 2 has a "mouth"-shaped structure. To facilitate the rotation of the disc-shaped part 11 and improve the welding efficiency, two sets of rolling support assemblies 3 are symmetrically fixed on both sides of the support frame 2. The two sets of rolling support assemblies 3 are located between the arc-shaped steel pipe 4 and the arc-shaped round rod 5. Each set of the rolling support assemblies 3 includes a first support rod 3.1, a second support rod 3.2 and a cylindrical ball bearing 3.3; one end of each of the first support rod 3.1 and the second support rod 3.2 is fixed to one side of the support frame 2, the first support rod 3.1 and the second support rod 3.2 are arranged perpendicularly to each other, and the cylindrical ball bearing 3.3 is fixed to the other end of each of the first support rod 3.1 and the second support rod 3.2, so that the disc-shaped part 11 can be rotatably supported under the action of the four cylindrical ball bearings 3.3. An arc-shaped round rod 5 is connected to the middle of the upper surface of the support frame 2, and the middle part of the arc-shaped round rod 5 is higher than the second support rod 3.2, so as to support and fix the disc-shaped part 11 and prevent it from tipping over, thereby realizing welding while the disc-shaped part 11 rotates, and improving the welding efficiency.

[0010] To realize cooling treatment on the welding portion of the disc-shaped part 11 during the welding repair process, an arc-shaped steel pipe 4 is connected to the middle of the upper surface of the support frame 2. One end of the arc-shaped steel pipe 4 is closed and the other end is a water inlet 4.1, and a plurality of upwardly spraying water spray holes 4.2 are formed on the arc-shaped steel pipe 4. The water tank 1 is filled with cooling water, a water pump 6 is arranged in the water tank 1, the water outlet end of the water pump 6 is connected to one end of a hose 7, and the other end of the hose 7 is connected to the water inlet 4.1 of the arc-shaped steel pipe 4; water flow is sprayed through the water spray holes 4.2 to the lower part of the welding portion of the disc-shaped part 11, so that the welding portion of the disc-shaped part 11 is rapidly cooled to dissipate heat, and the deformation of the part base material is prevented; the sprayed cooling water finally falls into the water tank 1 and can be recycled here, which avoids the waste of cooling water, and at the same time performs range management on the cooling water to avoid the impact on the surrounding environment.

[0011] For a relatively large disc-shaped part 11, in order to prevent it from tipping over, a support rod 8 is obliquely fixed on the side of the upper surface of the support frame 2 away from the arc-shaped steel pipe 4, and a thrust cylindrical roller bearing 9 is fixed to the top end of the support rod 8, which further improves the stability of the disc-shaped part 11 during welding.

[0012] Since metal scraps (such as welding slag, spatter, etc.) will be generated during the welding repair process of the disc-shaped part 11, and will fall into the water tank 1 below the position close to the arc-shaped steel pipe 4, which will affect the water pump 6. For this reason, a filter plate 10 is fixed in the middle of the water tank 1, and the water pump 6 is arranged on the side away from the arc-shaped steel pipe 4. The filter plate 10 is located between the arc-shaped steel pipe 4 and the arc-shaped round rod 5, so as to block the metal scraps.

[0013] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
