Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial automation, in particular to a processing equipment and a processing method. BACKGROUND

[0002] In the field of mechanical processing production, for long pipe workpieces assembled with disc structures, it is necessary to perform spraying or galvanizing treatment on the surface thereof, so as to improve the anti-oxidation performance and avoid rusting of the workpiece. However, after the galvanizing treatment, surface defects such as zinc slag and flow hanging are easily generated. These defects not only affect the appearance of the product, but also affect the assembly accuracy and use performance of the workpiece. Therefore, in the subsequent processing process, the surface defects such as zinc slag and flow hanging generated above must be removed. In the prior art, for the zinc slag removal operation of the long pipe with disc, manual polishing or semi-automatic equipment is usually used for treatment. In addition, during the previous processing or heat treatment process of the workpiece, small deformations are easily generated, so that the disc is no longer strictly perpendicular to the pipe body, or the pipe body itself is bent, that is, the concentricity may be deviated. These problems will affect the final quality of the product. In the prior art, the perpendicularity correction of the disc and the straightness correction of the pipe body are usually performed as independent and offline processes.

[0003] The prior art has the disadvantages that the manual polishing method has the disadvantages of high labor intensity, low production efficiency, unstable polishing quality and great influence of the technical level of the operator. The existing semi-automatic equipment usually has single function, and it is difficult to complete all processing contents in one system, so that the workpiece needs to be circulated between multiple independent workstations, thereby increasing the production rhythm and logistics cost. In addition, since the disc perpendicularity correction and the straightness correction require additional equipment and operators, multiple clamping needs to be performed, thereby introducing new error risks, and restricting the overall production and processing efficiency, resulting in process dispersion and long processing period.

After positioning the workpiece 1, a pushing force is applied to one end of the workpiece 1, so that the axial direction of the disc 11 is consistent with the axial direction of the workpiece 1, thereby correcting the assembly angle of the disc 11; After completing the disc calibration, the workpiece 1 is subjected to concentricity calibration. The workpiece 1 is controlled to rotate, and the bending degree of the workpiece 1 is judged by real-time feedback during rotation; It is judged whether the bending degree of the workpiece 1 meets the preset specified range. When the bending degree of the workpiece 1 is within the specified range, the workpiece 1 is discharged; When the bending degree of the workpiece 1 exceeds the specified range, an action force is applied to the workpiece 1, the direction of the action force is perpendicular to the axial direction of the workpiece 1, so as to straighten the workpiece 1 until the concentricity detection result of the workpiece 1 meets the requirement, so as to achieve the purpose of adjusting the concentricity of the workpiece 1, and the concentricity of the workpiece 1 is consistent. In step S4, the workpiece 1 after the concentricity calibration is cut, and is transferred to a specified position by the grabbing unit 3.
