Embodiment Construction

[0028] The traditional parts processing technology is: blanking - turning - heat treatment - electroplating. Due to the blindness of this kind of processing technology, the defective rate of the parts formed by the processing is relatively high. After the long-term accumulation of the inventor Based on the processing experience, the traditional parts processing technology is completely reformed. Through the calculation of the size chain, the process size of the production process is determined, and the parameters of the coating thickness of the parts are calculated, and the production process is strictly controlled in the production process to ensure the final product. Quality, parts formed by new processing technology have a high pass rate, and the precision has also been greatly improved.

[0029] The reformed processing technology includes the following steps:

[0030] Cutting—determining the size chain of parts—rough turning according to the size chain—heat treatment—fine ...

Abstract

The invention relates to a machining detection process for a part. The process comprises the following steps of: 1, blanking; 2, determining a dimension chain of the part; 3, roughly turning the material blanked by the step 1 according to the dimension chain of the part, which is determined in the step 2; 4, performing thermal treatment on the roughly-turned material; 5, accurately grinding the dimension chain of the part, which is determined in the step 2; and 6, electroplating a product obtained in the step 5. According to the machining detection process for the part, the qualified rate of the product is high, the machining accuracy is high, and process steps are rational.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and detection, and relates to a processing and detection technology of parts. Background technique [0002] The large aircraft industry is a strategic industry that highlights a country's comprehensive strength. Independently developing large aircraft is a long-cherished wish of the Chinese aviation industry. The large aircraft industry can promote the development of a country's basic science and basic industries and drive a large number of related industries. After more than 60 years of development, my country's aviation industry has already possessed the technical and material basis for manufacturing large-scale aircraft. There are a large number of large-scale aircraft parts, and each part must withstand the effects of heat load and environmental media. The mounting frame is a semi-finished part of a large aircraft. During the manufacturing process, in order to enhance its decorat...
