Embodiment Construction

[0031] Hereinafter, a description of preferred embodiments of the present invention will be provided in detail with reference to the accompanying drawings.

[0032] In this description, the detection method of the present invention is described in more detail by taking the airfoil mold tire of an aircraft as an example, but those skilled in the art should understand that the detection method of the present invention is not limited to only the wing of an aircraft. In fact, the detection method disclosed by the present invention can detect the actual score lines on other molded tires of the aircraft, and can also detect the molded tires in other mechanical manufacturing fields except aircrafts. The actual reticle on the screen is tested.

[0033] figure 1 It shows a schematic diagram of the theoretical score line of the airfoil mold tire 100 in the theoretical data model of the tooling, wherein the theoretical score line includes the cover line, the chemical milling line, the c...

Abstract

The invention provides a method for detecting an actual scribed line of a molded mould. The method includes the following steps: (a) points on a theoretical scribed line are selected from a data model for manufacturing the mould: (b) the selected points on the theoretical scribed line form a traveling track program capable of being operated by a numerical control machine tool; (c), the numerical control machine tool operates the traveling track program; (d), a tool head on the numerical control machine tool travels according to the traveling tack program so as to mark on the mould; (e), deviation between marks and the actual scribed line is compared; and (f) whether the deviation is a allowable value is determined. By means of the method for detecting the actual scribed line of the molded mould, after the mould is machined on the numerical control machine tool, detecting on a large-scale mould can be finished by adopting the detecting method in the field in time without moving the mould.

Description

technical field [0001] The invention relates to a method for detecting the actual score line of a molded tire, in particular to a method for detecting the actual score line of a molded aircraft wing surface mold tire. Background technique [0002] The surface shape of the airfoil molded tire changes slightly in the length direction, and the lateral change is relatively large. Each transverse section is a different airfoil-shaped space surface; the molded tire base is a steel structure, and the molded tire surface adopts a ring Oxygen resin casting, after casting, use CNC milling processing method to form curved surface and engraved lines. The shape line of the aircraft wing surface mold tire includes the part outline, front and rear beam centerline, station position line, flap outline and centerline, chemical milling area line, leak hole centerline and flap CPH hole centerline, etc. [0003] After the molded tire is produced and engraved on its surface, it is necessary to c...
