The invention relates to welding, in particular to devices for assembling a bottom with a shell.

The purpose of the invention is to simplify the design by providing a single drive for moving the bottom pusher and shell and increasing productivity by automating the changeover of the device to another size.

FIG. 1 schematically shows a device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2; in fig. 4 is a section BB in FIG. 3; in fig. 5 is a view of B in FIG. one.

The device consists of a frame 1, an electric drive 2, centering pushers 3 bottoms installed with the possibility of radial movement in guides 4, centering pushers 5 of the shell, made in the form of two shoulders spring-loaded 6 levers, pivotally fixed on pushers 3 bottoms. On the larger arm of the levers 5, floating wedge blocks 7 mounted by electromagnets 8 are mounted. On the pushers of the 3 bottoms the inclined spring-loaded springs 10 of the support 9 are pivotally fixed and moveable in the guides of the table 11 mounted between the pushers of the bottom 6 with the possibility of vertical movement. A rotary ring 12 is mounted on the drive shaft. The connecting rods 13 are hinged on the ring, the second ends of which are connected to the sliders 14 mounted in the guides 15. On the sliders 14, the rods 16 are attached to the hinges and wedge blocks 7 are worn. The brake 17 is installed with the possibility of braking the ring 12 relative to the frame 1. On the rails 4 the brake 18 is installed with the possibility of braking the ring 12 relative to the guides 4. On the pushers 3 bottoms are fixed

locking lugs 19 for fixing the position of the bottom 20 and locking lugs 21 for fixing the position of the shell 22 relative to the bottom. At the same time, a drive shaft 23 is installed in the frame 1 with the possibility of transmitting rotation through a conical pair 24 by means of a screw 25.

The device works as follows.

The bottom is placed on the table 11 with the braked ring 12 relative to the base 1 and relative to the guides 4. By switching on the actuator 2 by means of a bevel gear 24 and screws 25, the bottom 3 pushers are moved along the direction 4 until the pushers touch the outer surface of the bottom cylindrical part.

At the same time, the inclined supports 9, moving in the guides, lift the table 11 with the bottom 20 placed on it and with the help of springs 10 abut the bottom 20 into the lower abutments 19. At the stops 21, they place the shell 22. Brake the ring 12 relative to the guides 4 with the brake 17. By turning on the actuator 2, the guides 4 are rotated relative to the ring 12. In this case the connecting rods 13 push the rods 16, which with the help of the wedge blocks 7 rotate the spring-loaded levers around the axes fixed on the pusher 3 bottoms and the pushers of the shell 5, act on the outer surface be the sleeve, the sleeve edges aligned with the bottom edges. Turn on the brake 17 and turn off the brake 18 - ring 12 brake against the frame 1. Turning on the actuator 2 rotates the product in the process of setting tacks. Turn on the brake 18. Switch the actuator 2 and push out the pushers of the 3 bottoms, releasing the product. The springs 6 install the pushers of the 5 shells into the initial position relative to the pushers of the 3 bottoms.

The device will provide high-quality assembly of products of various sizes without readjustment of equipment.
