Abstract

The invention relates to the technical field of grinding and cleaning, and particularly discloses a constant-force pressing adjusting device for sealing surface cleaning operation. The device comprises a cleaning assembly, a spring assembly, a limiting screw assembly and an equipment carrying trolley, and the cleaning assembly is limited and fixed to the equipment carrying trolley through the limiting screw assembly; the distance between a grinding and polishing wheel in the cleaning assembly and the fixed sealing surface to be cleaned and ground where the equipment carrying trolley is located can be adjusted through the limiting screw assembly; and the spring assembly is arranged on the cleaning assembly, and the compression amount of the spring assembly is increased along with reduction of the distance between the cleaning assembly and the sealing surface to be cleaned and ground. The device is simple in structure, and the pressing force and the grinding force before operation can be adjusted without extra tools and operation experience; and meanwhile, the device has a self-adaptive flexible adjusting function, it can be guaranteed that the pressing force and the grinding force are constant in the operation process, and the device can work for a long time in a severe environment.

Description

technical field [0001] The invention belongs to the technical field of grinding and cleaning, and in particular relates to a constant force pressing adjustment device for sealing surface cleaning. Background technique [0002] In the industrial field, there are a large number of containers, pumps and other equipment that are sealed by flange connection. Rust or other foreign matter on the flange sealing surface directly affects the sealing effect. After regular maintenance, the sealing surface must be polished or polished. At present, it is a general trend to use automated equipment to clean the sealing surface, especially in the nuclear power industry. The RPV sealing surface cleaning machine can not only ensure the consistency of the cleaning effect, but also improve work efficiency and reduce personnel exposure. However, different objects have different requirements for grinding force, and the vibration during the cleaning operation causes the grinding force to change in ...
