Description

Technical Field

[0001] The present invention belongs to the field of mechanical processing, specifically to the technical field of mechanical processing fixtures, and in particular to a follow-up auxiliary clamping device for suppressing machining deformation. Background Art

[0002] Aerospace equipment manufacturing requires the machining and assembly of numerous thin-walled components, such as aircraft wing skins, spars, and wing boxes. These components, with their high aspect ratios and low rigidity, are susceptible to deformation and vibration during machining, severely impacting the precision and quality of the components. Particularly during drilling and milling, workpiece deformation and vibration can easily lead to out-of-tolerance hole or surface shape and position, and even cause machining accidents such as tool jamming and breakage, resulting in the scrapping of the workpiece.

[0003] There are two ways to process thin-walled structural parts: one is traditional manual processing, which is simple, fast, low-cost, and can cope with processing under different working conditions, but it requires a high level of technical skills from the operator, and the processing quality is difficult to guarantee. In order to suppress the processing deformation of the workpiece, the current method of adding technicians to synchronously support the rear of the processing area is often used. However, the auxiliary operation requires high coordination and is inefficient, which cannot meet the processing needs. The other is machine tool processing. In order to suppress the deformation of the workpiece and improve the processing quality, large-scale special fixtures are often used when using machine tools to support and clamp the components in a large-area covering manner to improve the rigidity characteristics of the processing area. This method is dedicated to a specific machine, has poor versatility, and is extremely costly. Therefore, how to suppress the processing deformation and vibration of the workpiece and achieve high-precision and efficient processing of the workpiece is an important problem that needs to be solved urgently.

[0004] Xu Yapeng et al.'s patent publication number is CN 114619074, and its invention name is "A device and method for quickly clamping and drilling thin-walled curved parts." The patent describes a clamping device for drilling holes on thin-walled curved surfaces. The device clamps the workpiece using two upper and lower universal clamping components to increase the local stiffness of the thin-walled part. However, the device has significant limitations and is only suitable for drilling holes on the edges of thin-walled parts. It also requires repeated disassembly and assembly during use, resulting in low efficiency. Chen Baolin et al.'s patent publication number is CN 113182907, and its invention name is "A flexible clamping device and clamping method." The patent describes a flexible clamping device that flexibly supports the workpiece on a machining platform through an array of independently vertically retractable cavities. This solution offers a certain degree of flexibility, allowing support based on the structural characteristics of thin-walled parts. It has the advantages of a wide range of applications and a high degree of automation. However, it is only suitable for milling operations and cannot clamp parts with enclosed cavities, such as aircraft wing boxes. Summary of the Invention
