Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machining, in particular to a wing part multi-intersection fine machining hole device. BACKGROUND

[0002] The "multi-intersection fine machining hole" is a key process of high-end manufacturing (especially in the field of aerospace, such as wing, fuselage joint), and the core is to realize "high precision, high consistency, high efficiency" precision hole making for spatially distributed multiple hole intersection points (such as cross holes of different part connecting surfaces, out-of-plane array holes).

[0003] The "multi-intersection" hole position is not a single plane / straight line distribution, but a spatial intersection point that meets the "part connection requirement". Typical scenarios include: part intersection intersection, such as the connecting hole of "spar (vertical surface) - rib plate (inclined surface)" of the wing (2 plane intersection hole positions); array intersection, such as the "multi-row out-of-plane hole" of the fuselage-wing joint (hole positions are arranged along the spatial curve, and the hole diameter / angle changes with the position); multi-layer connection intersection: such as the three-layer superimposed connecting hole of skin-stringer-separation frame (which needs to ensure that the hole position penetrates multiple layers and has coaxiality).

[0004] The existing wing part multi-intersection fine machining hole device has significant drawbacks in application: on the one hand, the "imprecise positioning" or "clamping deformation" of the wing part will directly cause hole position deviation. Since the wing surface is of irregular structure, it is difficult to stably support and place the hole making device during actual hole making operation, which is prone to cause position deviation of the hole making. At the same time, the clamping structure of the wing itself causes unpredictable damage; on the other hand, the hole making position of the wing is not a simple plane hole making, and accurate hole making is often required at narrow and inclined positions (such as vertical holes of the spar and inclined holes of the wing rib), so the required hole making device must have multi-azimuth angle conversion.

[0005] Therefore, a wing part multi-intersection fine machining hole device is needed. SUMMARY

[0050] Working principle: for multi-intersection finishing machining of such wing parts, the following aspects can be practically operated;

[0051] Firstly, when the device is placed on the metal surface where the hole needs to be drilled, the semicircular main groove 201 will change the angle under the limiting action of the resistance sliding rod 202 and the main frame 1 to best fit the metal surface, and at the same time, if it is in a position with uneven surface, the semicircular auxiliary groove 206 will change the angle under the limiting action of the limiting main shaft 203 and the main limiting plate 204 to better fit the metal surface; the semicircular auxiliary groove 206 will also change the angle within a smaller range under the limiting action of the limiting auxiliary shaft 207 and the auxiliary limiting plate 208 to meet the attachment operation of various types of metal surfaces, and the anti-skid strips 205 evenly distributed on the surfaces of the semicircular main groove 201, the semicircular auxiliary groove 206 and the semicircular auxiliary groove 209 can realize omnidirectional anti-skid operation on the metal surface to ensure the stability of the device itself;
