Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] Refer to attached Figure 8, When the boom tube is welded and formed, there will be a large concave or convex deformation near the weld. The deformation curve 100 is the contour of the cylinder 9 after welding, and the reference line 200 is the contour of the cylinder 9 when it is not welded. Each side of the barrel 9 has a deformation curve 100 and a reference line 200 . The correc...

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...
