Embodiment Construction

[0013] Since machined parts are complex parts with variable geometric shapes and impossible to be flat. Therefore, the structural shape of the part should be used to facilitate the establishment of the shape digital model with modern technology, and the surface data of the machined part should be taken out from the shape digital model, including the milling line on the part, the outer width line, the position line of the rib, and the position of various connection holes etc.; build a model.

[0014] Through computer drawing software, the surface of machine-added parts is virtually unfolded and calculated, and the frame-shaped parts and geometrically complex parts are unfolded into a plane state, and the orientation, position and size of the connecting holes of the parts are calculated. Based on the calculated results, use The CNC plotter draws the expanded mold line of the part.

[0015] Then, according to the expanded mold line of the part, the NC machining program is compil...

Abstract

The invention discloses a technological process of expanding and spraying a position of a hole on surface of a machine-made part. The main procedures of the technological process are as following: surface data of the machines-made part is obtained from a digifax to set up a model; the data of various patterns of the machine-made part surface is calculated and the surface is made to be virtually expanded. According to expanding calculation, a graph plotter draws an expansion line; numerical control processing numerically processes a flexibly-expanding orifice mould on an elastic plate or a sheet which is less than 1mm; in the process, machine-made part is positioned by the shape and the structure. An expanding orifice module is used to spray positions of all connection holes on the surface of the part and then drills are made. The invention adopts the flexibly-expanding orifice mould to localize the shape of the part and holes, which is rapid, correct, time-saving and low labor intensity. The flexibly-expanding orifice mould, which can be expanded and curved without deformation, can make the connection hole localized as standardized, reduce drilling cycle of various connection holes of machine-made parts and solve the problem that the machine-made part can not be expanded to be positioned on the plane.

Description

technical field [0001] The invention relates to a method for positioning drilling holes on the surface of mechanical parts. Especially the method of scribing and drilling on the surface of machined parts. Background technique [0002] In the known technology, for the method of drilling holes on the surface of sheet metal parts, usually before the curved surface sheet metal part is formed, it is unfolded into a flat state, and manual marking or template positioning is used to locate the hole positions. drilling. The geometric shape of machined parts is changeable, and it is impossible to form a plane state, let alone unfold into a plane complex part. Therefore, the drilling location on the machining parts is all drawn on the physical object by the workman at present. It is usually difficult for workers to draw lines with bare hands to ensure the identity of the connection holes of parts, and deviations of different hole positions often occur, and the errors caused by the a...
