SU1255265A1 - Drilling and riveting device - Google Patents

Description

The invention relates to machine-assembly manufacturing processes, as well as to the drilling and riveting of large-sized products, and can be used in the aviation, shipbuilding industry and other areas of mechanical engineering.

The purpose of the Invention is to expand the technological capabilities by providing riveting of closed contour products and increasing productivity.

This goal is achieved by sequentially stepping the device along riveted parts of a planar and curvilinear closed loop, drilling holes and rivets rivets after installation, instead of a drilling mechanism for riveting.

FIG. 1 shows a drilling ™ riveting device, side view; in fig. 2 - the same, top view; in fig. 3 - a drilling riveting device for riveting double curvature panels; in fig. 4 is a view A of FIG. 3.

The drilling-riveting device contains the main frame I and the additional frame 2 mirror-like with respect to it, the cdsda of which consists of moving the plates 3 and the base 4 relative to each other and the base 4, the relative movement of which is provided by the engine 5. The relative position of the plates and the bases of the main and additional frames is fixed by means of fixing units 6, which are made in the form of st. "; c, mounted on the slab and the base of the main frame, and in response to the authorized cartridges installed according to plate and frame ocHOBaHtm more «I

On each of the plates 3 main and

additional frames are installed with the possibility of longitudinal expansion along the guides 7 of the trolley 8 ,, on which they are mounted with the possibility of lateral movement along the guides 9, the carriage 10, the trolley 8 and the carriages 10 are driven by engines 11 and 12. On each of the The carriages 0 are equipped with interchangeable actuators consisting of a drilling-countersink head 13, which is replaced when riveted with a support with a device for inserting rivets on one carriage and a removable priztlcha 14, kneaded

with riveting on the riveting head - on another carriage. The alignment of the drilling-countersink head 13 and the clamp 14 is provided by a synchronization mechanism.

In order to drill holes in a certain order, the main frame moves along the template-conductor 15 fixed on the surface of the package being riveted, and the movement of the additional frame mounted on the back side of the package being riveted is matched with the main movement by means of a movement synchronization mechanism.

. The device works as follows.,

To perform the riveting work, it is necessary to fasten the template-jig 15 on the surface of the riveted product and, having drilled holes for it, to install the frames, install the main frame 1 on it, and an additional frame 2 is mounted on the reverse side of the riveting product frames 1 and 2 are interconnected by means of fixing units 6. After the frames are installed, the working cycle for drilling holes for rivets, during which the drill-countersink head, moving along the template-conductor 15, splits several rows of holes for rivets, as far as plates allow

3ram. To continue the work cycle

By drilling the holes, the main and additional frames are moved along the riveted seam, for which the fixing units 6 of the base 4 of the main frame 1 are unlocked and the base 4 of the main frame 1 moves along the jig template 15 along the seam. The base moves along with it.

4 additional frame 2. Their movement is consistent with each other through a synchronization mechanism. The bases of the frames fixed in the new position with the help of the fixing units 6 through the holes drilled by the head in the riveted package. Then, the plates 3 move in a similar way, fixing them, after which the cycle of drilling holes of the drill-countersink head is continued / pressed. After the passage of the device

along the entire seam, the mechanism for drilling the holes for the rivets is removed and replaced with the mechanism for riveting the rivets. And the device, setting and riveting the rivet, runs along the seam in the opposite direction.

The use of the proposed device allows us to provide an image.

Making holes for rivets, installing rivets and riveting them, rivet the products of a closed contour with a constant radius of curvature, to ensure the formation of joints. The proposed device does not limit the maximum dimensions of the riveted product.
