1,111,965. Assembling rubber bush mountings. REGIE NATIONALE DES USINES RENAULT. 20 May, 1965 [22 May, 1964], No. 21394/65. Heading F2S. [Also in Division B3] A machine for assembling mechanical parts comprises a polygonal stand 1 surmounted by a fixed polygonal turret 3, between which is placed a swivelling table 2 having a central opening, the stand and turret assembly being associated with interchangeable tools and working members, and further comprising a drive mechanism and cam members for driving the tools and working members off the drive mechanism. An electric motor drives a central shaft 12 via a reduction gear and bevel gears 13, 14 engage gears 15, 17 respectively, to drive mechanisms at the working stations located at the sides of the stand and turret. The reduction gear 7 also drives a shaft 19, which carries a plate 22. The plate is fitted with a peg 23 which engages in grooves 24 under the swivelling table 2 to form a geneva mechanism. The shaft 19 is movable axially by means of a cam 27, which engages a lever 230 pivoted to the shaft 19. The table 2 is held stationary by a dog 28 on a spring-loaded pivoted lever 29. The dog engages in the end of a groove 24 and is disengaged by the camming action of the plate 22 on the lever 29. In apparatus for assembling motor vehicle track rods, the socket 34 and ball 35 have been positioned in the housing on the rod 40 at the first three work-stations, and a spring 33 is to be positioned at a fourth station. The driven shaft 18 is journalled in bearings 37, 38 and actuating cams 44, 54, 55 are keyed thereon. The cam 44 coacts with a follower 45 carried by a lever 46, which actuates a bellcrank 51. Movement of the bell-crank moves a carriage 43 horizontally whereby a spring 33 is transferred from a support 39 to the track-rod housing by a gripping head 41 The cams 54, 55 move the head vertically and when the spring 33 is in position, the head, which includes a magnet (57), is raised while a push-rod (56) holds the spring in place until the magnet is clear, Fig. 5 (not shown). The times required to perform the work cycles at each station are substantially equal, but the longest cycle determines the time interval between successive rotary movements of the table 2. |
