A device for installing crackers includes a bed 1, a satellite fixing mechanism 2 mounted thereon 3; placed on the plate 4 of the bed 1, two mechanisms 5 for supplying crackers and four mechanisms 6 for pressing; together with two vibratory drives 7 and bowls 8, placed on the plate 9, four feeders 10 and two mechanisms 11 for installing crackers fixed on it,

Each of the cracker supply mechanisms 5 (FIG. 3) is made in the form of a power cylinder 12 connected to a gate 13 located in the housing 14 to which the support 15 is attached. The stroke of the gate 13 is limited by the cover 16. There are slots 17 for the feed crackers.

Above each slot 17 of the gate 13, there is one of the feeders 10, made in the form of a guide 18, two guides 19, fastened with brackets 20, and a pry guide rail 21, fixed

Each cracker installation mechanism 11 (FIG. 3) includes a power cylinder 24 mounted on an arm 25 and connected to a housing 26 moving in a sleeve 27, the sleeve with its flange and the bracket 26 are mounted on the plate 9 of the bed 1. From rotation about the sleeve 27 the housing 26 with a spring-loaded stem 28 (spring 29) is held by a key 30. A punch 31 is fixed on the flange of the housing 26, in which the collets 33 are mounted on the axes 32. The inner working surfaces of the collets 33 together with the outer working surfaces of the rod 28 form cylindrical cavities transition cabbage soup e into the cylindrical recesses 34 for placing crackers in them, which are overlapped by spring stops 35 mounted on the axles 36 of the collets 33. On the brackets 37 of the punch 31, the springs 39 are fixed together with the adjusting bolts 38, supporting the necessary working clearance in the cylindrical recesses -34 (Fig. .8).

The preload mechanisms 6 are mounted on the brackets AO on the plate 4 with respect to the corresponding collets 33 perpendicular to the grooves of the punches 31. Each prepress mechanism 6 is a sleeve 41 screwed into the threaded hole of the bracket 40, inside of which a plunger 42 and a spring 43 are placed (Fig. 8).

The assembled product, for example, the cylinder head 44 of the engines, includes two compression coil springs 45, two plates 46, two valves 47 and four crackers 48,

The operation of the device is controlled by the electrical circuit and the limit switch system.

The operation of the device for installing crackers is as follows. . Vibration drives 7 are fed from the bowls 8 in the oriented / oriented position of the crackers 48 to the feeders 10. The crackers 48 along the guides 18, 19 slide under the influence of their own weight in the slot 17 of the sliders 13 of the feeding mechanisms 5. The cylinder head 44 of the engines, assembled with springs 45, plates 46 and valves 47, on satellite 3 is fed by a conveyor (not shown conventionally). The incoming satellite 3, acting on the limit switch, turns on the locking mechanism 2, which lifts it and fixes it in the assembly area of the device, i.e. in the range of mechanism 1 for installing crackers. Then, cracker feeding mechanisms 5 are automatically turned on. Power cylinders 12 by moving crackers

48 into the cylindrical cavities 34 of the mechanism 11 by the sliders 13; Rusks 48 slide in cavities down to be placed in recesses 34,

overlapped by stops 35. After that, the mechanism 11 for installing crackers is included in the operation. The master cylinder 24 lowers the housing 26 with a punch 31 and collets 33 mounted thereon

with a rod 28, rusks 48 supported by stops 34. In this case, the punch 31 acts on the plate 46, compresses the spring 45 and releases the top of the valve 47. The rod 28 in the direction of compression, compressing the spring 29, abuts the valve 47, and the collet 33 with rusks 48 , supported by stops 35, slide along the valve stem 47, pressed against the last pushers 42 of the mechanisms 6. In the final lower position of the collet 33, the crackers 48 fall into the recess of the valve 47. Next, the power cylinders 24 return automatically, i.e. lifting of the casings 26. Pushers 42 of the mechanism 6, pressing the sliding collets 33 are already up, also

reliably hold the crackers 48 in the recess of the valve 47, the spring-loaded stops 35 moving upward slide easily along the dry belts 48, leaving them in the recess of the valve 47 At the same time, the punch 31 releases the spring 45 with the plate 46 while lifting, they assume the initial state - the crackers are installed 48 to the plate 45. In the final upper position of the housing 26, the stem 28 is returned to its original position by the action of the spring 29.

The fixation mechanism 2 lowers the satellite 3 with the assembled product onto the conveyor, feeding it to the next assembly position, and the next satellite enters the device with

the assembled product and the assembly cycle is repeated.
