Description

Technical Field

[0001] This utility model relates to the field of silencer technology, and in particular to a surface treatment device for boiler silencer production. Background Technology

[0002] Boiler silencers are generally cylindrical in shape. This cylindrical design is primarily based on a comprehensive consideration of acoustic performance, structural strength, and engineering practicality. The silencer is manufactured by rolling steel plates into a cylinder and then welding the edges, resulting in long weld seams on the surface. Defects such as porosity, slag inclusions, and cracks generated during the welding process significantly reduce weld strength. Grinding can thoroughly remove these defects, ensuring the integrity and sealing of the weld. Operators typically grind welds manually. Manual grinding is unstable and affected by fatigue and differences in experience. The grinding effect varies greatly between different parts of the same workpiece or between batches. The efficiency is only one-third to one-fifth of that of automated equipment, which is difficult to meet the needs of large-scale production. Utility Model Content

[0003] The purpose of this application is to provide a surface treatment apparatus for the production of boiler silencers, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: A surface treatment device for boiler silencer production includes a workbench and a grinding assembly mounted on the workbench. The grinding assembly includes a fixed frame, a movable frame, and an angle grinder. The fixed frame is fixedly mounted on the workbench surface, the movable frame is movably mounted on the workbench surface, and the angle grinder is movably positioned above the workbench. An arc-shaped plate is fixedly mounted on the top of both the fixed frame and the movable frame. The concave surface of the arc-shaped plate faces the angle grinder. Multiple rollers are rotatably mounted on the concave surface of the arc-shaped plate. The rollers are evenly distributed on the concave surface of the arc-shaped plate. The rollers are elongated cylindrical in shape, with slightly pointed ends made of rubber. The ends of the rollers are connected to the concave surface of the arc-shaped plate via bearings.

[0005] Preferably, the workbench has a groove on its surface, and a slider is fixedly installed on the bottom surface of the movable frame, the slider being embedded inside the groove. A motor is fixedly installed on the workbench, and a screw is mounted on the workbench via a bearing, the screw being driven by the motor. A threaded block is fixedly installed on the movable frame, the threaded block being threadedly connected to the screw. A fixed rod is fixedly installed above the workbench, and a movable rod is sleeved on the end of the fixed rod. One end of the movable rod is connected to the outer wall of the fixed rod via a torsion spring. The angle grinder is fixedly connected to the end of the movable rod, and a handle is fixedly installed on the end of the movable rod, with the grinding end of the angle grinder facing the workbench.

[0006] The beneficial effects of this utility model are: by providing a grinding component to replace manual grinding, and by providing an auxiliary structure that combines a handle and an angle grinder, the accuracy and stability are improved, and the grinding quality is enhanced.

[0010] like Figure 1-3 The surface treatment device for boiler silencer production shown includes a workbench 1 and a grinding assembly mounted on the workbench 1. The grinding assembly includes a fixed frame 2, a movable frame 3, and an angle grinder 12. The fixed frame 2 is fixedly mounted on the table surface of the workbench 1, the movable frame 3 is movably mounted on the table surface of the workbench 1, and the angle grinder 12 is movably positioned above the workbench 1. An arc-shaped plate 6 is fixedly mounted on the top of both the fixed frame 2 and the movable frame 3. The concave surface of the arc-shaped plate 6 faces the angle grinder 12. Multiple rollers 7 are rotatably mounted on the concave surface of the arc-shaped plate 6. The rollers 7 are evenly laid on the concave surface of the arc-shaped plate 6. The rollers 7 are long cylindrical in shape, with two slightly pointed ends made of rubber. The ends of the rollers 7 are connected to the concave surface of the arc-shaped plate 6 through bearings.

[0011] A groove 4 is formed on the surface of the workbench 1. A slider is fixedly installed on the bottom surface of the movable frame 3, and the slider is embedded in the groove 4. A motor 5 is fixedly installed on the surface of the workbench 1. A screw 8 is installed on the surface of the workbench 1 via a bearing. The screw 8 is driven by the motor 5. A threaded block is fixedly installed on the movable frame 3, and the threaded block is threadedly connected to the screw 8. A fixed rod 11 is fixedly installed above the surface of the workbench 1. A movable rod 9 is sleeved on the end of the fixed rod 11. One end of the movable rod 9 is connected to the outer wall of the fixed rod 11 via a torsion spring. An angle grinder 12 is fixedly connected to the end of the movable rod 9. A handle 10 is fixedly installed on the end of the movable rod 9. The grinding end of the angle grinder 12 faces the workbench 1.

[0012] Example: The welded muffler housing is transported from the production line to the arc plate 6 of the fixed frame 2, and the housing is placed with the weld side facing the angle grinder 12. The housing passes through the roller 7, which rotates on the arc plate 6 to guide the movement of the housing. When the housing moves, the operator pulls down the handle 10, which drives the angle grinder 12. The angle grinder 12 drives the movable rod 9, which rotates on the fixed rod 11. The torsion spring is twisted and deformed, and the grinding disc of the angle grinder 12 contacts the weld of the housing, grinding the entire weld as the housing moves. When the housing moves, one end of the housing moves to the arc plate 6 of the moving frame 3. To ensure the smooth operation of the housing, the motor 5 is started, driving the screw 8 to rotate. The screw 8 drives the moving frame 3 to move on the worktable 1. The slider of the moving frame 3 moves in the slide groove 4. The moving frame 3 follows the movement of the end of the housing, always maintaining a supporting state, which is conducive to the smooth operation of the housing.
