Using method of machining and clamping device used for screen display diffraction supporting component

Abstract

The invention discloses a using method of a machining and clamping device used for a screen display diffraction supporting component. A clamping base is arranged on a workbench, a heightening block isarranged on the clamping base, and a component blank is arranged on the heightening block; before the component blank is machined, two rounds of high-low temperature aging heat treatment are conducted on the component blank, and then milling and rough machining are sequentially conducted with large allowance; semi-finish machining and finish milling machining are conducted on the component blank,a pressing plate is detached after finish milling machining is completed, the screen display diffraction supporting component with the component blank obtained after finish machining as a finished product is taken down to be packaged, and machining of the screen display diffraction supporting component is completed; and according to the screen display diffraction supporting component, through preheating treatment on a blank state, internal stress can be avoided to a great extent, part deformation is reduced, mutual cooperation and relative positions of parts can be guaranteed, precision afterlong-term use can be guaranteed, the machining quality stability of the modified parts is improved, and it is ensured that a pilot can accurately observe, identify and control.

Description

technical field [0001] The invention relates to the use of a processing and clamping device for screen display diffractive parts, in particular to a method for using the processing and clamping device for screen display diffractive supporting parts. Background technique [0002] At present, modern head-up displays place the screen in front of the cockpit to display important information to the pilot in intuitive forms such as images and characters. The pilot controls the flight information and its equipment through the positioning data, and the pilot can grasp the information while looking ahead. Relevant and important information put the two together for observation and identification; when the screen display diffraction support part is processed by the machine tool, due to the complex structure, the material has stretch characteristics after being subjected to temperature changes. During processing, the internal stress of the screen display diffraction support part is relea...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the existing screen display diffractive support parts through machine tool processing, due to the complex structure, the material has stretch characteristics after being subjected to temperature changes, during processing, the stress release inside the screen display diffractive support parts is not complete, and the processing Deformation, the accuracy of the cooperation between the screen display diffraction support part and the connecting part, and the position and size are out of tolerance. When the screen display diffraction support part is deformed, it will affect the positioning accuracy of the screen display diffraction connection part. These problems are common in the industry It has been difficult to solve the complicated and miscellaneous diseases. The deformation of the screen display diffraction support parts affects the information received and transmitted by the connecting parts, and directly affects the pilot's observation, identification, and control; through a reasonable design, a processing of the screen display diffraction support parts is now provided. The use method of the clamping device; the screen display diffraction support part of the present invention can largely avoid the internal stress generated during the casting of the blank through the pre-heat treatment of the blank state, and avoid the post-process processing with internal stress. ;Release the processing stress of the blank to ensure the consistency of the part size
