Embodiment 1

[0040] Such as figure 1 , 9 shown.

[0041] A double-sided processing deformation control method, through the clamping equipment, both sides of the part II are in a machinable state, and at the same time, according to the adjustable range of the part in the blank I, the blank is divided into an adjustable area V and an unadjustable area III, IV , in the non-adjustable areas III and IV, by adjusting the inter-layer processing sequence, in the adjustable area V by adjusting the position of the part in the blank to control the deformation of the part, consider all the features of both sides of the part in the finishing stage, and optimize the double-sided finishing sequence . The adjustable area and the non-adjustable area refer to the upper surface of the web where the part is at the upper limit position of the blank as the dividing surface, and the area between the upper surface of the web of the part and the upper surface of the blank in the thickness direction is defined as...

Embodiment 2

[0055] Such as Figure 2-8 shown.

[0056] A double-sided processing deformation control clamping equipment, which includes: an overall support 1, a structural frame 2, a horizontal movement base 3, a vertical lifting platform 4, a clamping element 5, a force sensor 6, a displacement sensor 7, a dynamic Auxiliary support device 8, such as figure 1 shown.

Abstract

The invention discloses a double-sided processing deformation control method and equipment, which is characterized in that it divides the blank into an adjustable area and an unadjustable area according to the adjustable range of the position of the part in the blank, and monitors the deformation in the adjustable area. The data adjusts the position of the part in the blank; in the finishing stage, all the features of both sides of the part are considered at the same time, and the sequence of double-sided finishing is optimized, so that the deformation of the part is small after the final machining is completed. In order to realize this processing method, a double-sided processing deformation control equipment was invented, which can process both sides of the part through one clamping under the premise of ensuring the clamping force and processing stability, and at the same time through the displacement sensor Monitor part deformation data. The invention ensures that the final deformation of the parts is small, and at the same time realizes automatic and intelligent clamping.

Description

technical field [0001] The invention relates to a precision machining machining technology, in particular to an anti-deformation processing technology for web parts, in particular to a double-sided machining deformation control method and equipment. Background technique [0002] Large-scale aviation parts have complex shapes and high material removal rates. After processing, due to the redistribution of internal residual stress, the workpieces are often severely deformed or even scrapped. How to control the deformation of aircraft structural parts is very important. Processing on both sides of the part can balance the processing deformation caused by material removal. Now the commonly used double-sided processing method is to repair the benchmark on both sides, then carry out rough machining on side A—manual turning over—rough machining on side B—manual turning Surface - A side semi-finishing - manual turning - B side semi-finishing - manual turning - A side finishing - manu...
