Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a polishing machine for valve processing. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to its function, it can be divided into shut-off valves, check valves, regulating valves, etc. The valve is a control component in the fluid conveying system, and has the functions of shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. The valves used in fluid control systems, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. The valve needs to be polished using a polishing machine during the processing process to prevent the user from being scratched by burrs on the surface of the valve. Publication number: CN212330657U discloses a polishing machine for valve processing, including a polishing machine body, the output end of the polishing machine body is transmission-connected to a polishing wheel body, the front of the polishing machine body is provided with a wheel cover body sleeved on the surface of the polishing wheel body, the top of the polishing machine body is fixedly connected to a connecting block, and the top of the polishing machine body is provided with a positioning plate. The polishing machine for valve processing rotates the cam to change the position of the side with a higher horizontal surface of the cam and the other side, and at the same time pushes the positioning plate upward to rotate clockwise with the connecting block as the axis. When the front end of the positioning plate is out of contact with the surface of the wheel cover body, the wheel cover body is pushed to open and out of contact with the polishing wheel body, thereby achieving the effect of facilitating the removal of the wheel cover body, solving the problem that the existing polishing machine is not convenient for users to remove the wheel cover, which affects the replacement efficiency of the polishing wheel and is not convenient for users to use. However, when the above technology is used, the polishing position of the valve is fixed, so that the polishing angle cannot be effectively adjusted during the polishing process. At the same time, when the valve is clamped and fixed, the valve is not effectively protected, which may cause damage to the valve surface, so it needs to be improved. Utility Model Content
