Abstract

The invention discloses a cylinder correction device and method. The cylinder correction device comprises a first ring body and at least one correction unit, the first ring body is used for being placed in an inner cavity of a to-be-corrected cylinder, and the at least one correction unit comprises a plurality of correction assemblies arranged in an annular array outside the first ring body. Eachcorrection assembly comprises a fixing sleeve, a correction rod and a correction part, wherein the fixing sleeve is fixedly arranged in the first ring body, the axis of the fixing sleeve is perpendicular to the axis of the first ring body, and the fixing sleeve communicates with the inner cavity of the first ring body; the correction rod is arranged in the fixing sleeve in a sliding mode and can move along the axis of the fixing sleeve; and the correction part is arranged at one end, away from the first ring body, of the correction rod and can rotate around the axis of the correction rod to move outwards to abut against the inner wall of the to-be-corrected cylinder. The cylinder correction device and method can correct cylinders of various specifications, and are simple and convenient tooperate.

Description

technical field [0001] The invention relates to the technical field of circle calibration equipment, in particular to a cylinder calibration device and method. Background technique [0002] After the welding process of the cylinder is completed, there is often the case that the cylinder is elliptical. For the cylinder, workers often enter the cylinder cavity and use a jack to correct the roundness. When the cylinder is corrected, the hydraulic jack is often used to add a support rod, and its existence correction The defect that the direction is single and the support rod cannot be used multiple times. [0003] In the prior art, the Chinese invention patent with the publication number CN102357565B discloses a cylinder hydraulic automatic correction machine, which includes a fixed bottom platform, a gantry frame, a cantilever beam, a hydraulic system, a mold cabinet and a control cabinet. A mobile platform is provided with a driving mechanism, a tensioning mechanism and a cen...
