Automatic correction method and intelligent cylinder correction machine

Abstract

The invention discloses an automatic correction method and an intelligent cylinder correction machine, and the method comprises the following steps: S1, lifting a workpiece: enabling the workpiece to be automatically centered, clamped and straightened, S2, scanning the shape: scanning the width size of the workpiece, S3, carrying out deformation analysis: obtaining a deformation curve of the workpiece, S4, correcting the workpiece: dividing the workpiece into a plurality of sections, wherein the control system performs internal and external correction on the workpiece section by section through the external correction mechanism and the internal correction mechanism; s5, rechecking the size: specifically, the appearance size of the workpiece is checked, and if the workpiece is qualified, workpiece correction is ended; otherwise, repeating the steps S2-S5 until the product is qualified; the intelligent cylinder correction machine comprises a portal frame, a bottom platform, a movable platform, a centering mechanism, an outer correction mechanism, an inner correction mechanism, a cantilever beam, a height detection mechanism and a control system. Compared with the prior art, the method and the machine are high in automation degree and high in correction speed. In the correction process of the cylinder, all-directional correction is achieved on the cylinder, the correction precision is high, and the probability of repeated correction is small.

Description

technical field [0001] The invention relates to the technical field of correction after workpiece deformation, in particular to an automatic correction method and an intelligent correction machine for cylinders. Background technique [0002] The boom of a crane is generally welded by upper and lower parts. Because the length and wall thickness of the boom cylinder are large, there will be a large concave or external shape near the weld when welding is formed. Convex deformation. This deformation must be corrected to meet the design requirements before it can become a qualified product to ensure the normal operation of the crane. The patent with the publication number of CN102357565B provides a cylinder hydraulic automatic correction machine, including a fixed bottom platform, a gantry frame, and a cantilever beam. , hydraulic system, mold cabinet and control cabinet, the control system analyzes the deformation of the workpiece according to the data of the workpiece's extern...
