MECHANIZED ASSEMBLING APPARATUS Russian patent published in 1994 - IPC

FIELD: motor-car industry. SUBSTANCE: apparatus has screw driving heads 2 with drives of longitudinal movement and rotation; devices to switch rotation drives off, provided with path cut-out mechanisms 3 with spring-loaded pushers 4; operational organs to drive screws, made in the form of mounted in each head free relatively each other movable drivers 5 and embracing them centering bushes 6 and coupling of limiting driving tight torque. Driver 5 in each head is connected with centering bush 6 so as to be capable for joint rotation, for example, using square rod 7, that is set in square hole 8 of bush 6, connected with spindle shaft 14 of head 2 by coupling of limiting driving tight torque. The latter has driving semicoupling 11 and driven semicoupling 12, that are provided with engaging with each other cams 13. Driving semicoupling 11 is connected with spindle shaft 14 so as to be capable for joint rotation ( for example, using splines 15 ) and to move in axial direction. Driven semicoupling 12 is stationary connected with centering bush 6( for example, using threading ) and is connected with spindle shaft 14 with capability of mutual turning and longitudinal movement. Each head 2 has individual rotation drive 10. Each head 2 device to switch rotation drives off has pressing disk 16, mounted on spindle shaft 14 with capability of longitudinal movement and engagement with driving semicoupling 11 and with spring-loaded pusher 4 of path cut-out mechanism 3. Pressing disks 16 are spring-loaded relatively to stationary mounted bodies 18 of screw driving heads 2. Each body 18 has mounted on it path cut-out mechanism. EFFECT: apparatus is used for mechanization of assembling operations. 2 cl, 7 dwg
