Description

one ,

The invention relates to watchmaking technology.

The known device for the automatic assembly of the wheel system of a clock, comprising mechanical arms for supplying plates and a set of tribune-wheel assemblies, does not allow assembling the wheel system at one position and does not provide high accuracy of fixing the mating surfaces of the assembled parts.

The proposed device differs from the well-known in that it is equipped with a mechanism for pre-fixing the lower and upper plates along a contour, made in the form of a turntable with contour sockets for the lower boards and mounted above them moving holders for the upper boards, and the mechanism for the approach of the boards made in the form of a vertically movable feeder with base pins, the feeder of the upper board is provided with cylindrical sockets with lead-in cones for fixing the screws to Repleni fees.

This makes it possible to increase the accuracy of assembly and ensure the assembly of the wheel system on one position.

FIG. 1 shows the proposed device with a fixed assembly table; in fig. 2 - vacuum holder mechanical. Hands, section; in fig. 3 - holder for upper board, plan view.

The device contains a rotary table 1 with contour sockets 2, one of which has a bottom plate 3, a movable spring-loaded holder 4 for the top plate 5, a lower feeder 6 with base pins 7 and an upper feeder 8 with base pins 9.

A set of tribe-wheel units 10 is installed in the vacuum grip 11 of the mechanical arm 12. The upper feeder 8 has a screwdriver 13 and sockets 14 for fixing the screws 15 for fastening the plates.

A set of tribe-wheel units 10 is based in the cheeks 16 (see Fig. 2), having half holes for the necks of the tribes. The air in the vacuum grip 11 is sucked off through the channels 17. The plates 3 and 5 are fixed along the contour by pins 18 and 19 and are spring-loaded

lever 20 (see Fig. 3).

The device works as follows.

Bottom 3 and top 5 boards with screws

fasteners 15 are installed respectively

in the contour sockets 2 of table 1 and the holder 4. Mechanical arms 12 are inserted between the boards, in the grips And which a set of interlocking tribe-wheel 10 assemblies are installed. holes and the mating of the support holes of the boards with the trunnions of the set of tribre-wheel 10 assemblies. The upper feeder 8 centers down the mechanism fastening screws 15 using the slots 14. Upon completion of the approach of the plates, the screws 15 are screwed with a screwdriver 13 mounted on the feeder 8. Object of the Invention A device for automatically assembling the wheel system of a clock, including mechanical arms for supplying the boards and a set of tribre-wheel assemblies, characterized in and ensuring the assembly of the wheel system at one position, the device is equipped with a mechanism for preliminary fixation of the lower and upper plates along the contour, made in the form of a rotary table with contour sockets for the lower points atm and mounted above them movable in the vertical direction toolholders for the upper boards, and boards Approaches mechanism made in the form of movable in the vertical direction with the supplies base pins, wherein the top board is provided with a feeding cylinder jacks with lead-in cone for fixing the board fixing screws.
