Commonly used coating materials include paint, resin, paint, etc. A fixture refers to a tool used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection. The special fixture for anti-corrosion treatment of the brake steel back of EMUs is a tool that fixes the brake steel back of the EMU through two plywood and then sprays it with coating material.

[0003] After searching, a Chinese utility model patent with patent number CN213468334U discloses a brake pad painting fixture, including a bottom plate, a positioning plate is arranged at the center of the bottom plate, support plates are arranged on both sides of the bottom plate, a slide groove is arranged on the inner side of the support plate, a clamping plate is slidably connected to the slide groove, a sponge gasket and a rubber gasket are fixedly connected to one side of the clamping plate, a sliding rod, a sleeve rod and a spring are fixedly connected between the connecting block and the positioning plate, and two suction cups and a sponge block are arranged on the top of the bottom plate. The advantages of the utility model are: the positioning of the fixture and the brake pad is completed by the positioning plate, the positioning is accurate and fast, and the positioning plate also has a certain fixing effect, and the sponge gasket and the rubber gasket can be clamped Brake pads of different shapes can be fixed more firmly by arranging suction cups on the bottom plate, and sponge blocks can be arranged on the top of the bottom plate to fit closely with the friction blocks of the brake pads to prevent the friction blocks from being stained with paint when spraying paint. However, although sponge gaskets and rubber gaskets can clamp brake pads of different shapes, the brake steel back needs to be connected with multiple parts, and there are connecting holes of different sizes inside it. When the clamp is spraying paint on the brake steel back, only the surface of the brake steel back can be sprayed, and the inner walls of the connecting holes of different sizes cannot be completely sprayed with anti-corrosion coating. After the brake steel back is used for a long time, the inner walls of the internal connecting holes are corroded, causing the parts to loosen and fall off. Therefore, a special clamp for anti-corrosion treatment of brake steel backs for EMUs is proposed to solve the above problems. Utility Model Content

The solenoid valve 6 is opened, and the coating material is sprayed from the spray head 3. Due to the different spilling angles during rotation, the inner walls of multiple connecting holes inside the brake steel back are covered with spray. The adjustment mechanism 5, The invention is beneficial to spray-coating the connection holes of different sizes inside the brake steel back, preventing the inner wall of the connection holes of the steel back from being corroded, and improving the service life and safety of the brake steel back. It solves the problem that the brake steel back in the Chinese utility model patent with patent number CN213468334U needs to be connected with multiple parts, and there are connection holes of different sizes inside. When the clamp is used to spray paint the brake steel back, only the surface of the brake steel back can be sprayed, and the inner wall of the connection holes of different sizes cannot be completely sprayed with anti-corrosion coating.
