Abstract

The invention provides a speed-variable supersonic flame spraying spherical device which comprises a revolving platform, an auxiliary belt wheel, a shaft, a sprayer, a ball table, an auxiliary motor belt wheel, an auxiliary motor, a clamp, a head stock, a main motor, a main shaft, a main belt wheel, a main motor belt wheel, a touch screen, a PLC (Programmable Logic Controller), a main frequency converter, an auxiliary frequency converter and the like, wherein the ball table, the clamp, the main shaft and the main belt wheel are connected, the main shaft passes through the head stock, the main motor is connected with the main motor belt wheel, the sprayer is fixed on the revolving platform, the auxiliary belt wheel, the shaft and the revolving platform are connected, the auxiliary motor is connected with the auxiliary motor belt wheel, the touch screen and the PLC are both electrically connected with the main frequency converter, the main motor and the auxiliary frequency converter by leads, the PLC is provided with a program which can generate continuously changing angular velocity according to the change of the turning radius of each point on a spherical surface, but keeps a constant linear velocity, as well as is provided with a constant rotating speed program of the sprayer, and moreover, a function relation exists between the angular velocity of the spherical surface and the rotating angle of the sprayer. Uniform and consistent coatings with required thickness can be obtained by selecting proper rotating velocity programs of the main shaft and the revolving platform on the touch screen.

Description

Technical field [0001] The invention relates to a supersonic flame spraying spherical surface device capable of realizing uniform coating thickness of the spherical surface. Background technique [0002] The sphere of the ball valve is in the shape of a ball table. At present, when supersonic flame spraying tungsten carbide is carried out on the spherical surface of the table, it is generally used to clamp the workpiece on the spindle of the bedside box, clamp the nozzle of the spraying device on the rotary table, and the spindle and the rotary table. Each table rotates at a certain speed, and the nozzle sprays tungsten carbide on the spherical surface, because each point on the spherical surface rotates around the center of gyration at the same angular velocity, but the radius of gyration is different, so the linear velocity of each point is different, and the nozzle sprays tungsten carbide at the same angular velocity. The rotation speed sprays the spherical surface, resul...
