Abstract

The application discloses a wind power tower cylinder welding error edge amount correction mechanism and relates to the technical field of wind power single pile thick plate processing. The mechanism comprises a correction platform and a connecting plate. A servo motor is arranged on the front side of the correction platform, and a lead screw is arranged on the output end of the servo motor. The mechanism is positioned by a limiting assembly one, a limiting assembly two and an adjusting assembly. The arc-shaped fixing plate body is attached to the surface of the tower cylinder and the single pile thick plate to realize stable clamping. The hydraulic rod one and the hydraulic rod two are used for accurate driving position adjustment. The servo motor and the lead screw are used for uniform speed transmission. The axial movement and the longitudinal error edge correction of the tower cylinder and the single pile thick plate can be accurately controlled. The error edge amount meets the welding standard. Meanwhile, the rollers of the auxiliary assembly reduce the moving friction, the scrapers clean the debris in real time, the components are prevented from being jammed, the correction stability and the accuracy are further improved, the safety hazards such as weld cracking and component deformation are reduced, and the service life of the wind power tower cylinder and the single pile is prolonged.
