Abstract
The utility model discloses a kind of bore dia auxiliary selecting device, it is characterised in that include that a bullet with handle, bullet surface have 4 grooves being evenly distributed.During use, cone surface fits with hole inwall, will do four labellings with pen at the four of cone grooves and hole contact internal walls point, and corresponding four labelling points make cross wire, then two diameters for two of hole 90 ° of angles each other of cross wire.The accuracy that this utility model positions during can improving hole machined, reduces foozle.
Description
Technical field
This utility model relates to a kind of bore dia auxiliary selecting device, is particularly suited for during aircraft manufacturing the diameter in existing hole on structure member and chooses and measure work.
Background technology
During aircraft manufacturing, there is an existing hole in the parts such as aircraft deckle board, needs the position according to this hole, and determining that the hole site of a new perforate, the position of new perforate determine needs the diameter in existing hole by ruler measurement stroke on deckle board.There is bigger error in the whole process measuring existing bore dia of painting, and operating process is comparatively laborious.
Utility model content
The purpose of this utility model is to provide a kind of bore dia auxiliary selecting device, and during aircraft manufacturing, on aircraft components, the bore dia auxiliary in existing hole is chosen, and is drawn on deckle board by the diameter in hole.
This utility model is made up of four grooves in an aluminum cone and cone.Cone top has one end cylinder as handle, and four grooves are evenly distributed in cone surface, and every two adjacent scribe line centrages are 90 ° with the angle of cone rotary shaft line.
During use, cone slowly being put in the existing hole of aircraft components, after rotating cone gently, cone surface fits with hole inwall.With pen, the four of cone grooves are done four labellings at the contact internal walls point of hole.Then taking out cone, do straight line with two labelling points of ruler super-interval, corresponding four labelling points make cross wire, then two diameters for two of hole 90 ° of angles each other of cross wire.
Technique effect of the present utility model: the accuracy positioned during improving hole machined, reduces foozle, improves work efficiency, reduce workman labour force.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is for using schematic diagram.
Detailed description of the invention
This utility model is during aircraft manufacturing, it is known that the bore dia auxiliary in hole is chosen.Being overall structure figure in accompanying drawing 1, a bullet with handle, bullet surface has 4 grooves being evenly distributed.Actually used method illustrates as a example by accompanying drawing 2, and bore dia assists selecting device 1 put in measured workpiece 2 slowly, and rotating hole diameter auxiliary selecting device 1 allows it fit with the hole wall on workpiece 2 gently.Face scribe line at bore dia auxiliary selecting device 1 does four marks with workpiece 2 joint place with thin marking pen, then takes out bore dia auxiliary selecting device 1, will be connected two-by-two with ruler, define two crossing diameters through center, hole in four marks.In the fabrication process, can output and there is the new bore of position relationship using ready-made diameter as benchmark with this hole.
Further, bullet is aluminum cone, its light weight, cone top has one end cylinder as handle, article four, groove is evenly distributed in cone surface, and every two adjacent scribe line centrages are 90 ° with the angle of cone rotary shaft line, and line width is 1mm, the degree of depth is 1mm.
