The invention relates to mechanical engineering, in particular, to devices for forming permanent joints by riveting.

The purpose of the invention is to improve the quality of the riveting of a package of parts from flat materials, as well as improving productivity by providing a double-sided, pressing a riveted package, as well as automatically feeding one of the assembled parts into the riveting zone.

FIG. 1 shows the proposed device, the cut; figure 2 - the position of the collected package in the initial stage of Assembly; on fig.Z - submission of the lower washer; in fig. 4 - the final formation of the compound.

The device contains a bracket 1, on which support 2 and a rivet punch 3 are coaxially mounted, the ends of which are made conical, the power cylinder 4 and the clamping mechanism ..

The clamping mechanism consists of a sleeve 5 with a flange 6 installed concentrically to the rivet punch 3 A nut 7 and a lock nut 8 are installed at the end of the punch. The sleeve 5 is connected to the rivet punch 3 by means of a spring 9, the ends of which are fixed on the flange 6 and the nut 7. Drive sleeve 5 of the clamping mechanism is made in the form of two Bowden cables, the shell 10 of the first of which is fixed on the flange 6, and the ton of ha 11 is on the bracket

the shell 12 of the second is fixed on the bracket, and the ha ha 13 is on the flange 6. On the bracket 1, at the support 2, an elastic compression element 14 is attached, which interacts with the bag 15 on the support part 16 and with the upper washer 17 installed. 18 filing one of

assembled parts in the riveting area.

The device works as follows. . .

A package of 15 parts assembled on the bearing part 16, with

the installed washer 17 is fed to the riveting zone before the longitudinal axis of the package is combined with the support 2 axis and the rivet punch 3. The washer 19 is fed into the riveting zone by the feed mechanism 18 until its axis coincides with the axis of the rivet punch. After that include the drive sleeve 5 of the clamping mechanism, the transmission link of which is made in the form of Bowden cables. The shell 10 of the Bowden cable, moving in the direction of the bracket 1, moves the flange 6 with the sleeve 5. At the same time, by means of the spring 9, the riveting punch 3 moves in the same direction. When the last and sleeve 5 are moved upwards, the washer 19 is fed from mechanism tray 18 filing and dressing her on the bottom

the edge of the sleeve 20 package. In this case, the sleeve of the assembled package is fixed by the conical parts of the support and the punch. The washer 19 is in contact with the free edge of the elastic element 14,

fixed with one edge at the support on the bracket 1.

Upon further upward movement of the sleeve 5, the compression force acts simultaneously on the upper 17 and lower 19 washers of the package 15. The rivet punch 3, resting with its conical part into the sleeve 20, stops, and the sleeve 5 continues to move up, stretching the spring 9, and packet compression with the necessary effort. After that, a command is issued to turn on the ram 4, which with its rod acts on the rivet punch 3. Riveting of the edges of the sleeve 20 occurs and the rod of the ram 4 is returned to its original state. The final release of the assembled package of parts occurs due to the pull-in of the pull-rod 13. inside the shell 12 of the second Bruden cable.

The use of Bowden cables in the device as a transfer element of the bag presser mechanism allows the feeding and assembling of one of the package parts, as well as simultaneous two-way compression of the bag before riveting.

the invention

A riveting device containing a bracket, at the ends of which there is a coaxially mounted support and a riveting punch with a power cylinder, as well as a bag presser mechanism, executed in the form of that, in order to improve the quality of riveting of a package of parts made of flat materials, as well as to increase productivity, it is equipped with a mechanism for feeding one of the riveted rivets to the zone and a elastic element installed on the support, the sleeve of the pressing mechanism is flush with the flange at one end, is relatively spring-loaded relative to the punch in the axial direction and is connected with the drive of reciprocating movement by means of

two trodo in Bowden, the shell of the first of which is fixed on the flange of the sleeve, the edge of the socket is on the bracket, and the shell of the second is fixed on the bracket, the edge of the socket is on the flange

fixed on one edge by supporting bracket 1. With a further upward movement of the sleeve 5, the compression force acts simultaneously on the upper 17 and lower 19 washers of the package 15. The riveting punch 3, resting on its conical part against the sleeve 20, stops, and the sleeve 5 continues to move upward, stretching the spring 9, and compresses the package with necessary effort. After that, a command is issued to turn on the power cylinder 4, which acts on the riveting punch 3 with its rod. The edges of the sleeve 20 are riveted and the rod of the power cylinder 4 returns to its original state. The final release of the assembled package of parts occurs by pulling the rod 13. into the sheath 12 of the second Bowden cable. The use in the device of Bowden cables as a transmission link of the package clamp mechanism allows the supply and assembly of one of the parts of the package, as well as the simultaneous two-sided compression of the package before riveting. A riveting device comprising a bracket, at the ends of which a support and a riveting punch with a power cylinder are mounted coaxially, as well as a packet clamping mechanism made in the form of a concentric placed concentric with the sleeve and connected with the reciprocating drive of the sleeve, characterized in that, for the purpose of To improve the quality of riveting a package of parts from flat materials, as well as to increase productivity, it is equipped with a mechanism for supplying one of the riveted parts to the riveting zone and an elastic element mounted on To the support, the bushing of the me2θ clamping mechanism is made with a flange at one end, axially spring-loaded relative to the punch, and connected to the reciprocating drive by means of 25 two Bowden cables, the shell of the first of which is fixed to the sleeve flange, the thrust edge is fixed to the bracket, and the shell . the second is fixed on the bracket, the edge of the rod on the flange 30 of the sleeve.
