Embodiment approach

[0034] 1) According to the design requirements of the parts to be processed, select a blank with a suitable size. In this embodiment, an aluminum alloy pre-stretched sheet is used as the blank material. On the basis of the size of the part to be processed, the machining allowance and the materials required for the process boss are reserved. ; After the blank is blanked, smooth the reverse surface of the blank, according to Figure 7 The positions 601 to 606 in the figure are at the peripheral position of the blank for countersinking manufacturing process bosses for clamping, and the bolt fixing module 30 is used for fixing; a suction cup fixing module 20 is set at the middle position 607 of the part to be processed, and the Set a vise fixing module 40 at the position 608 of the rib structure of the part, set a round head fixing module 50 at the position 609 of the raised structure of the part to be processed, fix the above-mentioned clamp modules on the adjustment module 80 res...

Abstract

The invention discloses a clamp system suitable for a large-sized wallboard thin-walled workpiece. The clamp system comprises a pedestal, a plurality of adjusting modules and a plurality of clamp modules. The multiple adjusting modules are fixedly connected to the pedestal. The multiple clamp modules are fixedly connected to the multiple adjusting modules in a one-to-one correspondence mode. The multiple clamp modules are used for clamping the thin-walled workpiece. The adjusting modules comprise height adjusting units, pressure sensing units and fixing units. The pressure sensing units are connected to the height adjusting units, and the fixing units are fixedly connected to the pressure sensing units. The height adjusting units are used for adjusting the heights of the pressure sensing units and the fixing units so as to adjust the heights of the clamp modules. The pressure sensing units are used for detecting the pressure to the clamp modules by the thin-walled workpiece. The fixingunits are used for being fixedly connected with the clamp modules. By means of the clamp system suitable for the large-sized wallboard thin-walled workpiece, rough machining, stress relief and finishmachining of the large-sized wallboard thin-walled workpiece can be conducted on the same machining platform, workloads are reduced and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the processing field of large weakly rigid thin-walled parts, in particular to a fixture system suitable for large-scale thin-walled wall boards. Background technique [0002] In the modern aviation industry, large integral aerostructures directly processed from large blanks have become an important part of aircraft structures. Large-scale aerospace structural parts have significant advantages such as improving the strength and reliability of the fuselage, reducing the weight of the fuselage, reducing the number of parts and assembly workload, etc. The processing deformation of structural parts is difficult to control. [0003] The out-of-tolerance machining deformation of aeronautical structural parts will affect the subsequent assembly and service performance of parts, and even cause safety accidents; School shape. However, the current shape correction process is still immature, which requires a lot of manpower and materia...
