The pressing mechanism is made in the form of a ram cylinder 11, the rod 12 of which is hollow, a traverse 13 fixed on the end of the rod, three successively and pivotally interconnected levers 14, 15, 16 and a stop in the form of a bracket 17. The lever 14 is fixed to the free end the yoke 13, and the lever 16 is installed with the ability to interact with the punch 18. The bracket 17 is mounted on the base with the ability to interact with the yoke through an intermediate support element - the roller 19.

The core mechanism is installed under the press-in mechanism and coaxially with it and includes a cylinder - battery 20, a piston cylinder - block 21, a piston block 22, block 23 itself mounted for axial movement in the stem cavity 12 of the power cylinder 11 and spring-loaded relative to the rod , a valve 24, and also a floating block of cores 25. On the basis there is a magnetic holder 26, which serves to base one of the component parts of the ley-plate.

The feed mechanism of the fastener components includes a hopper 27, a feed chute 28, a housing 29, a rotary table 30 with receptacles 31, a safety clutch 32, a block of control lugs 33 fastened in the groove 34 of the table 30, a microswitch 35, a drive circuit, from the engine with a gear 36 and bevel gears 37, an electromagnet 38, a latch 39 and a spring 40.

The screwing mechanism consists of a block of screwdrivers 41, a drive for moving it in the form of cylinders of vertical feeds 42, horizontal - 43, a drive of rotation 44, an adapter 45 with a shank 46 and a screwdriver 47, a sleeve 48 with a fastener holder 49 and a grip 50.

The feed mechanism of the component part — the plate consists of a power cylinder connected to its rod of gear rack 51 of the gear shaft 52, mounted in the base supports with the possibility of rotating the sleeve 53 mounted on the shaft with the possibility of both axial movement and rotation relative to it, mounted on the sleeve lever 54 with magnetic clamps 55, and

also mounted on the base of the bracket 56. The gear shaft 52 engages with the rail 51. A shaft groove 57 is made on the shaft 52, with which the pin 58 fixed on the sleeve interacts.

The Q is made with guide grooves 59 and in them is placed a retainer 60 mounted on the bracket 56. Near the grippers 55, there are orienting rods 61.

Assembled parts are a base case 62 and components -

5, an insertable sleeve 63, a plate 64 and screws 65 for fastening the plate.

The device operates in a closed automatic cycle by sequentially switching on the mechanism according to commands from co.,. Some switches, time relays, and pressure relays (not shown) are as follows.

Before switching on the vibrating hopper 27 for screws 65, the magazine 7, the device 8 for picturing the plates 5 must be loaded and the feed mechanism 5 fasteners must work - i.e. the complete screws must be in the original position. Installed in the fixture case part 62 and the sleeve 63 in the npneivt0 nest punch 18.

The start button is turned on. Turns and lowers the clamps of the body part clamp. When the pressure of the pneumatic network required for clamping is reached, the rest of the mechanisms start working. The mechanism of pressing in the bushing is activated, with the gripped plate it is raised, rotated, the lever of the component supply unit is lowered, and the plastic is transferred

tina in the installation area. The plate is attracted by the magnetic holder, and the lever returns to its original position, attracting another plate, which is raised by the device for the piece of output. At the same time, the screwing mechanism is working - the screwdrivers block is lowered from the initial state, the screws are taken from the turntable, lifts them to the upper position, moves horizontally to the mounting area, lowers the screwdriver block with screws into the plate holes and threaded housings, the rotation of the motors is turned on - the screws are turned. The pitch mechanism begins to work. After it is triggered by the pressure switch command, included in the battery circuit, the mechanism begins to retract, unclamping the case part. The cycle is over. Removing the assembled cap and installing a new one.

Individually, the mechanisms work in the following way.

The pressing mechanism starts working when in the cylinder 11 a working medium, for example air, is supplied under the piston. The piston together with the brush 12 and the crosspiece 13 are moved upwards, through the levers 14, 15, 16 the movement is transmitted to the punch 18 with the sleeve 63, which is pressed into the body part 62.

The kernel mechanism works after receiving the command that the fasteners are wrapped. Before this, the working medium under the same pressure was in the cylinder-accumulator 10 and in the cylinder 21 under the valve 24. In the beginning of operation, the cavity of the cylinder 21 under the valve communicates with the atmosphere, the valve 24 is lowered, the striker 23 instantly moves and its impact on the floating block of cores 25, which strikes the body part 62 about 3 screws, flattening the thread.

The feeder fasteners works as follows.

The screws from the vibrating hopper 27 move along the chute 28 to the housing 29 and rest against the cylindrical surface of the turntable 30 until the engine 36 is turned on. After turning on the engine, rotation to the table 30 is transmitted through bevel gears 37 and safety clutch 32. Together with the table, a block of control stops 33 rotates, consisting of 4 cams, which act alternately on the microswitch 35, and he gives the command to turn on the electromagnet 38 and the latch 39 leaves the table 30 to rotate during those moments when mnye okazyvayuts socket 31 coaxial with the supply tray 28 and the conductive screw falls into the next slot. At these moments, the drive rotates, the safety clutch slips.

The screwing mechanism works as follows.

With a vertical feed of the screwdriver, together with the sleeve 48, the holder of the fastener 49 is fed, which, with its conical and cylindrical surfaces, covers the screw, and the grip 50 latches it. When supplying a screwdriver with a screw into the wrapping zone, the latter rests against the hole, the sleeve 48 continues to move until the screwdriver 47 rests against the screw. The rotation of the actuator 44 is turned on while its feed continues until the end of the wrapping. Compensation for the inconsistency of the movements of the screwdriver 47 and the sleeve 48 is provided by their spring loading.

The feeder component plate 64 operates from the power cylinder. When pressure is applied to one of its cavities, the rail slider 51 must turn the sleeve 53 through the shaft 52 and the sleeve 53, but this is prevented by the retainer 60 entering the groove 59, so the sleeve will start to rise vertically and the finger 58 to slide along the screw copier the groove 57 until the transition of its right cutting into the left, at the same time ends the vertical groove 59 on the sleeve. At this moment, the sleeve 53 holds nothing and it, together with the shaft, rotates by an angle corresponding to the length of the horizontal portion of the groove 59 until the latch 60 rests on another vertical groove on the sleeve. The rotation of the shaft continues, so the movement of the sleeve will be directed downward, the orienting rods 61 will fall into the holes in the plate 64, and the magnetic grip 55 will take the plate from the magazine 7. When pressure is applied to the other cavity of the cylinder, reverse movements occur when the plate is installed in the mounting location on case details.
