Embodiment 1

[0026] Such as figure 1 As shown, a general and efficient clamping method for aerospace structural parts is to install a general backing plate 2 designed and manufactured according to the size of the workbench on the workbench where the structural part 1 is processed or measured, and the general backing plate 2 is provided with multiple The telescopic support rod 3 replaces the backing plate artificially placed by the testing or processing personnel according to the shape of the structural part 1 in the prior art. The support rod 3 is provided with a suction cup that can generate suction to fix the structural member 1, so that the structural member 1 is closely attached to the support rod 3, replacing the process of adding a pressure plate on the structural member 1 by testing or processing personnel in the prior art. When the structural part 1 is processed or measured, the structural part 1 is placed on the general backing plate 2, and the supporting rod 3 required to support...

Embodiment 2

[0034] This embodiment is improved on the basis of the above-mentioned embodiment. The improvement is that: before step (1), there is also step A: the craftsman writes the clamping program file according to the shape of the structural part 1, and determines the position of the structural part 1. Clamping position, and mark the required supporting position of structural part 1, upload it to the data control center of structural part 1 clamping process, realize the file sharing of structural part 1 clamping program, and facilitate processing or testing personnel to retrieve the shape of structural part 1 and support position, no temporary on-site analysis of the support position of the structural part 1 is required, which saves the time for re-analysis when the structural part 1 is processed or measured.

[0035] The general backing plate 2 is connected with remote control devices that can remotely control the valves on the hydraulic pipeline 5 and the vacuum pipeline 4, such as: h...

Abstract

The invention discloses a universal efficient clamping method for an aviation structural part. According to the universal efficient clamping method, a universal backing plate which is manufactured according to the size of a workbench is mounted on the workbench used for the machining or measuring of the structural part; a plurality of telescopic supporting rods are arranged in the universal backing plate; the universal backing plate can replace a backing plate which is manually placed by testing or machining personnel according to the shape of the structural part in the prior art; and suckingdiscs capable of generating the suction and fixing the structural part are arranged on the supporting rods, and then the structural can cling to the supporting rods, thereby replacing the working procedure that a pressing plate is added by the testing or machining personnel on the structural part in the prior art. By adoption of the universal efficient clamping method provided by the invention, the problem about the frequent replacement of clamps during the machining or measuring of different structural parts can be solved, the workload of the machining or measuring personnel can be reduced, and the potential safety hazards in the process of adding a cushion block and the process of adding the pressing plate can be reduced.

Description

technical field [0001] The invention relates to the technical field of numerical control machining of aeronautical structural parts, in particular to a universal and efficient clamping method for aeronautical structural parts. Background technique [0002] In the manufacture of aerospace structural parts, products are often put into production in small batches or even single pieces. When measuring and processing parts, parts need to be positioned. Some parts are deformed and warped. During measurement, a pressing force is needed to offset the deformation. However, due to For small batch processing, replacing clamping fixtures and pressing parts will take a lot of time and bring a large workload to processing or measuring personnel. Before the invention of this technology, standard pads were usually used to temporarily analyze the support points according to different parts. According to the deformation of the parts, the pressure plate is temporarily added to offset the defor...
