Abstract

This invention relates to riveting and assembly work. The purpose of the invention is to increase the reliability and performance of the assembly. The device includes a housing 1, a base 2 on which a cradle 3 and a jig 4 are mounted. In the latter, a cavity 7 is made, communicating, and with a source of compressed air, and guides are mounted in which the sleeves 10 are mounted in with a radial clearance. On the base 2, a recess and an annular cavity 13 are made. In the recess with a gap, there is a spacing, a bed 3. The bearing 17 is placed on a bed 3, which is lifted up to the stop in the jig 4. The rivets are fed through the channels 19 of the jig 4. Under the action of compressed air entering the cavities 7 and 13, and then through the tangential channels into the radial gaps between the guides and sleeves 10 and between the lateral surfaces of the reservoir 3 and the recess, the sleeves 10 and the lodgement 3 oscillate in a certain area bounded by a gap . This does not allow the openings of the upper and lower semi-separators to overlap. The sending of rivets into the holes of the half separators of bearings is carried out by pushers 12 3.

Description

channels 11 and 15 - to the radial gaps between the guides 9 and the sleeves 10, as well as between the lateral surfaces of the cradle 3 and the recess.

Air coming from cavity 13

The invention relates to riveting and assembly work, in particular, to devices for grouping rivets into the holes of assembled articles, for example, half separators of ball bearings.

The purpose of the invention is to increase by 5 through channels 16 under the bottom part the rigidity of the assembly and performance of item 3, creates for the latter an aerostatic support. Under the influence of air, the sleeves 10 perform ascillating movements, and the cradle 3 oscillates

: ditch, excluding overlap of holes in the cavity, perpendicular to the longitudinal axis for the presence of dimensional dimensions during their installation.

The rivets that fall from the channels 19 into the sleeves 10 also perform rotational-ascillating movements in the area bounded by a gap e. The oscillations of the bed-3 in the recess, also limited by the gap e, do not allow the holes of the upper and lower semi-separators to overlap. Rip rivet auto searching and preliminary rivet entry

 rigidly fixed to the body of 1 part 2Q hole. Final shipment of 5 and 6. In part 5 of the conductor, riveting is performed in the holes of the semi-separators; cavity 7, communicating with by means of under the influence of push-pushers; Cera 8 with a source of compressed air. new 12.

 In addition, in part 5, the proposed device allows the guides 9 to be worn, in which the reliability of the assembly can be placed, especially when the bushings are 10, installed in fine use of small-sized rivets, and with radial clearance e and capacity due to reduction in time: possibility of movement in the plane, per-: pendicular to the longitudinal axis of the device. ; The cavity 7 of the conductor with the internal cavities of the guides 9 is connected via tangential channels 11. A coaxially automatic device for grouping the exception of compressed air contact with the rivet, narrowing the orientation area of the rivets by adjusting the back alignment.

FIG. 1 shows the device: a general view; in fig. 2 shows section A-A I in FIG. one; in fig. 3 - section BB on

The automatic device for group mounting of rivets comprises a housing 1, a base 2 on which a cradle 3 is mounted, a jig 4. The latter consists of

assembly process.

Claims (1)

Invention Formula guides-punches 12 are mounted on guides 1 on base 1. On base 2, a recess and an annular cavity 13 are made. In the recess a lodgement 3 is arranged to form gaps between the lateral and bottom surfaces of the lodgment and recess, respectively, and can be moved in a plane perpendicular to the longitudinal axis devices. 35 The rivets' BOIs, mainly in ball-holders, containing a base on which the housing is mounted, a cradle for the assembled ball-support body, a source of compressed air, a jig made with a cavity communicated with the indicated source of compressed air, and evenly aligned circumferentially guided channels with an annular cavity, the pusher. The size of the radial gap e is chosen equal to twice the total tolerance of 40 li-punches placed in guides, the location of the holes s in poluseparatore. and rivet tubes, the annular housing cavity 13 is connected via a choke 14 to a compressed air source, and through channels 15 and 16 to a side and bottom surfaces of the recess. The device works as follows. Angled to guides, characterized in that, in order to increase assembly reliability and productivity, it is provided with bushings installed in guide rails with a radial clearance and the ability to move in a plane perpendicular to the longitudinal axis of the device, the base is made with communicating with each other by means of the bearing 17 assembled with the upper and lower semi-separators is placed on the lodgment 3, which rises with the support up to the stop with part 5 of the conductor recess and the annular cavity of the torus 4. O There is a cut-off and the supply of the cradle is placed in the recess with the rivets through the tubes 18 and the conductor inlet channel 19. Air under pressure enters through fittings 8 and 14 in cavities 7 and 13, and from there through tangential rum between the lateral and end surfaces of the lodgement and the recess, and the annular cavity of the lodgement is connected with a source of compressed air. channels 11 and 15 - to the radial gaps between the guides 9 and the sleeves 10, as well as between the lateral surfaces of the cradle 3 and the recess. Air coming from cavity 13  through channels 16 under the bottom part of the bed 3, it creates an aerostatic support for the latter. Under the influence of air, the sleeves 10 perform ascillating movements, and the cradle 3 oscillates  to improve the reliability of the assembly, especially the use of small-sized s performance by reducing the automatic device for assembly process.
