Accurate locating structure and method of metal embedded part in composite

Abstract

The invention relates to an accurate locating structure and method of a metal embedded part in a composite. The accurate locating structure comprises the metal embedded part and an intermediate body.After prepreg is laid on the surface of the metal embedded part, compression molding is conducted, and the formed piece is the intermediate body. Inner and outer locating device holes are reserved onthe intermediate body. The intermediate body is fixed to a female die through locating devices. According to the accurate locating structure and method of the metal embedded part in the composite, accurate locating of the metal embedded part is achieved in the manner of screwing a bolt from the outside of the female die to the intermediate body locating portion, machining of the intermediate bodycan guarantee the position precision and flatness requirement of the metal embedded part, and finally by means of locating of the intermediate body to the female die, accurate locating of the metal embedded part in the composite product is achieved finally; and the position precision and flatness requirement of the metal embedded part are guaranteed.

Description

technical field [0001] The invention relates to a precise positioning structure and positioning method, in particular to a precise positioning structure and positioning method of composite metal embedded parts. Background technique [0002] Because composite materials have excellent properties such as high strength, high modulus, and light weight, composite materials have been widely used in aerospace, medicine, automobiles, rail transit and other fields. Since composite materials have many interface requirements that require threaded connection of electronic components, parts, etc., traditional metal materials can be directly formed into threads to connect with other parts, which is difficult to achieve directly with composite materials, and metal parts can be embedded in composite materials , Process threaded holes on embedded metal parts to connect electronic components, parts, etc. At present, for composite materials that require high interface position accuracy and fla...

Problems solved by technology

However, for composite materials with interfering structures, it is impossible to form first and then process. We can only choose to process the embedded metal parts with threaded holes first, and then form them together with the composite materials. However, the precise positioning of metal embedded parts is difficult.
