Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a device and method for disassembling and assembling a brake mechanism of an electric actuator. Background technique [0002] The main function of the brake mechanism is to control the adjustment accuracy of the electric control valve and maintain the current position of the valve. If the brake mechanism is loose, worn or damaged, it will cause overshoot or hysteresis in the adjustment process of the electric control valve, and in severe cases, it cannot be maintained. The state of the valve causes the valve to close or open under the action of the system medium, which affects the safe and stable operation of the system. Therefore, the quality of disassembly and assembly of the brake mechanism is particularly important. On-site disassembly and inspection of the brake mechanism requires disassembly and assembly of the brake mechanism, which usually requires the coope...
