Servo valve development whole process error prevention system

Abstract

The invention discloses a servo valve development whole process error prevention system. A front-end error prevention processing module integrates the design link and the process link of a space servovalve, a design drawing and a test specification for the servo valve meeting task book design requirements are determined, machining, assembling and debugging processes are compiled, and three kindsof key characteristics of design key characteristics, process key characteristics and process control key characteristics corresponding to servo valve development whole process weak links are determined; indexes of all requirements in the design drawing and the test specification need to be quantified; a middle-end error prevention processing module carries out processing and assembling accordingto machining and assembling processes based on the design drawing determined by the front-end error prevention processing module, each size can be ensured to meet drawing requirements, and the three kinds of key characteristics during production and assembling processes recognized by the front-end error prevention processing module are strictly controlled; a terminal error prevention processing module carries out debugging according to the debugging process, each performance index can be ensured to meet test specification requirements, and the three kinds of key characteristics during the debugging process are controlled strictly; and delivery is carried out after debugging.

Description

technical field [0001] The present invention relates to the quality control technology in the field of aerospace servo, and specifically relates to the error prevention technology for the whole process of servo valve product development of aerospace servo. As long as the technical method of the present invention is followed to advance the development process, human error can be effectively avoided. Background technique [0002] At present, for China, the traditional quality management mode of aerospace is the "quality problem zeroing" mode that deals with quality problems after the event and draws inferences about other cases from one instance. According to the five requirements of "accurate positioning, clear mechanism, problem recurrence, effective measures, and drawing inferences from one instance", implement them one by one, and form a technical zero report or technical document. Only through the review of relevant technical experts and technical leaders can the product r...

Problems solved by technology

[0004] The traditional zero-return mode of aerospace quality management is very serious. However, this is a quality management mode that deals with problems that have occurred in the development and production process after the fact. This quality management mode cannot predict, prevent and correct errors. Elimination, so as to greatly increase the production efficiency of enterprises, reduce the chance of human error, "afterwards" zero control method, will cause waste of cost, cycle, manpower and material resources

Although foreign countries have developed an error-proof management model for some products, there is no precedent for the systematic error-prevention technology and method system of the entire process of aerospace servo valve product development at home and abroad.
