The invention relates to electrical engineering, in particular to a device. for assembly of suspended high-voltage insulators.

The purpose of the invention is to simplify the design.

FIG. 1 depicts. Magiina, general view; in fig. 2 - the same, plan view; in fig. 3 is a section A-A in FIG. I; in fig. 4 - section B - B in FIG. one; in fig. 5 is a sectional view BB in FIG. I; in fig. 6 is a cross-section of the FIG. four.

The machine for assembling insulators consists of three positional mechanisms for the transfer of products, two actuating mechanisms, one for one, for assembling and reinforcing high-voltage insulators, a drive mechanism with a cam and lever system and a final product tip, the number of positions in which should be equal to the number of positions, for example, the cradle of the insulator drying unit, or the number of cells in one row of the packaging.

The central positional mechanism of non-: product transfer, installed on the I- frame: (Fig. 1) with wedge-shaped nanoplane-1m 2, has one more position,; there are a number of positions in the accumulator and is stepwise ( group) stop 1i-tel, consisting of a movable carriage 3, on the side walls of which two axes 4 are installed in the nods of innics (fig. 1 and 2), with several pairs hooked on them; grabs 5 (fig. 1 and 3 ), the ends of which are made of structural (unalloyed: gummy) steel (to cover foot gaps when closing the grips due to their {def rmatsii). On each axis 4 are rigidly fixed on one lever 6 (Fig. 3), interacting through the grooves with the glitter 7, on the axis of which the rollers 8 are mounted.

The slider 7 slides along the guides mounted on the frame of the trolley 3. In the front part of the trolley 3, on its sides, there are longitudinal grips 9, connected by a pull 10 with extreme grips 5. The connecting rod 10 with grips 5 and 9 is ball, which ensures its rotation at a certain angle in two rows of x.

Trolley 3 connecting rods 11 is connected to the crank of the drive mechanism. Moving the carriage back and forth is limited by adjustable, stops 12. Above the carriage, along its longitudinal axis, on brackets

13, mounted on the frame 1, the levers 14 are mounted with support rollers, on which they are mounted on the lifting frame 15, having the opportunity to interlace but with the guide 16, fixed rigidly on the frame, only vertically.

From the bottom of the lifting frame 15, the front part is hingedly suspended by the frame 17, and the rear part of them is fixed to the frame,

Q which is fixed by retainer 18. The lower and upper planes of the frame 17 are alternately in contact with the rollers 8 of the slide 7. The levers 14 and 19 are connected to the lever arm 20, on which the roller is in contact with the mechanical cam. Under each position on the lifting frame 15 (on its axles) self-tightening knots 21 are installed.

Each self-tightening knot consists of a spring-loaded seat 22 (FIG. 3) with a groove with which the grips 23 are in contact, pivotally mounted on the butt-lift frame. The design of snap 5 and 23 can be varied, as it depends on the shape of the manufactured products.

5 The actuating mechanism consists of a vibrator 24 (Fig. 1), posted to the nlite 25, mounted on shock absorbers on the skeleton 1. On the plate 25 there are two detachable sliding substrates 26, which have a shaft with cams 27 mounted

0 and 28 (Fig. 1, 4, 5). An elastic coupling 29 with a ratchet mechanism (Fig. 2) is installed at the end of the shaft, allowing the shaft to rotate in one direction only.

Two actuators of similar design are installed on the slab - the vibration mechanism and the assembly mechanism. Each actuator consists of a bracket 30 and 31 with grooves for the direction of the undo rails — external 32 and 33 and internal 34 (FIG. 4) and 35 (FIG. 5).

0 In the upper part, brackets 36 and 37 are fastened to the external rails, which are adjustable in height, on which spring-mounted crosses 38 and 39 are mounted, and in the center of the axes on levers 36 and 37 in the vibration mechanism is mounted a self-clamping

5 tapered stop 40 (Fig. 4), in the assembly mechanism - pneumatic cylinder 41 with snap (Fig. 5).

To the clutches of the cylinder 41 are attached nanravle 42 for rods, which coincide (with the upper arrangement of the lever 37) with the guides of the accumulator rods 43 (Fig. 2 and 5) (structure not shown) or with the guides, made by Yuida rods or other products.

Brackets 44 and 45 are attached to the inner rails 34 and 35 in the lower part. On the latter, self-tightening hubs 21 are installed, and from the bottom - rollers 46 adjustable at the height (Figures 4 and 5). In the vibration mechanism, to the bracket 44 are hinged (fig. 6) on the axles there are two hollow petals 47 with nozzles, forming a hollow jacket around the product, to the outside of which water is supplied through the hoses from the valve. On the inner surface of the shirt of petals there are several rows of fine holes (nozzles) through which water flows under small pressure to flush the rest of the mixture from the outer surface of the caps.

The rubber half rings 48 are fixed on top of the petals. Two rollers 49 are installed on the sides of the bracket 44. On the fixed axis of the bracket 30 there are two levers with rollers 50. The outer and inner rails in the assembly mechanisms and vibrations contact the gear-gear block 51 mounted on the axles brackets 30 and 31. Gear unit 51 consists of two gears with different numbers of teeth, which provides movement, for example, an insulator stem by a larger amount, compared to the movement of the bottom product, for example, an insulator cap. At the bottom of the bracket 30 there is a water supply valve 52 (FIG. 4) to the hollow petals 47, and on the bracket 31, an air supply valve 53 (FIG. 5) to the pneumatic cylinder 41.

The position of the assembly mechanism is attached below the feed mechanism, for example, the caps of the insulator, the construction of which is in principle similar to the design of the central positional transfer mechanism of products. The cap feeding mechanism consists of a longitudinal rail 54 (FIGS. 1 and 2), connected at one end to the carriage 3, and a cross rail 55 (FIG. 2), directed along the feeder mechanism. ,

The transverse rail 55 is rigidly connected to the slider transfer cap 56 (Fig. 2 and 5). The rails 54 and 55 are in contact with the gear wheel 57 (Fig. 2), which is mounted on an axis rigidly fixed to the skeleton 1. The number of teeth in the gear wheels of the block 57 may vary depending on the required movement step of the products. The housing for gear unit 57 has guide bushings along which slats 54 and 55 slide (not shown).

The second end of the rail 55 slides along a fixed guide bushing 58. The second side of the slider 56 slides along a fixed guide rod 59. On each side of the slider 56 there are racks 60 (Fig. 5), on which two levers 61 are hingedly fixed, on the upper ends of which are fixed spring, slightly curved at the ends, gripping rails 62. The lower ends of the levers 61 are in contact with the groove of the slide with the rollers 63, the design of which is similar to the design

Slider 7.

A lifting frame 64 is mounted between the transverse rail 55 and the direction of the lower arm 59, resting on the levers 65 and 66 interconnected by a pull 67. On the lifting frame 64, the frame 68 is hingedly mounted similarly to frame 17 in the frame 17. Т ha 67 flexible tons The goy 69 is connected to the lever 20. Two self-tightening knots 21 are installed on the lifting frame 64, one of which is located below the hopper drive 70, which has a slam-shut 71.

The drive mechanism consists of electro

motor 72 (fig. 2), gearbox 73, on the low-speed shaft of which a partial gear 74 is installed (fig. 1) in the form of a sector with a number of teeth equal to the number of teeth of the full gear 75 mounted on the secondary shaft 76 (fig. 1 and 2) . The angle of the sector of gear 74 is selected based on the ratio of the transfer of products to the total cycle time of the machine, which takes place during one revolution of the shaft of the gearbox 73. A lever with a roller 77 is mounted on the shaft of the gearbox 73

(Fig. 1 and 2), acting on the lifting bed of the accumulator 78, which has a self-tightening knot 21 and a product cutter. A conic gear 79 is mounted on the gearbox shaft 73 (FIG. 2),

entering into engagement with the gear 80, the shaft of which is connected by the coupling 29 with the shaft of the cams 27 and 28.

Gear ratio in gear x 1: 1. On the secondary shaft 76 there is a cam 81 in contact with the roller of the lever 20

and cranks with spring compensators 82, connecting rods 11 connected to carriage 3. Gears 74 and 75 are in contact with retainer 83. By design, retainers 18 and 83 can be mechanical (triggered by spring), electromagnetic

or pneumatic, which depends on the required accuracy of fixation of these mechanisms.

The machine works as follows. Initial position. Trolley 3 and slider 56 are in the far left

their gripping units are closed and the products they hold. Lifting frames 15 and 64 are lowered, and their self-tightening knots are opened. Site under

drive 78 glass parts omitted and its self-locking knot is opened. In the extreme positions of the accumulators 43, 70, 78, before start-up, the necessary items for assembly or revision should be placed. The vibrator and the electric motor of the drive mechanism operate continuously.

: The rotation of the output shaft of the gearbox 73: is clockwise. In the moment

the beginning of the initial position of the incomplete gear 74 is disengaged from the gears: it 75, which is fixed by the latch 83.; Continuing to rotate, the low-speed shaft of the reducer 73 is rotated through a pair of tapered gear 79 and 80 rotates the shaft with the cams I and 27 and 28. The cam profiles are made so that at the beginning of the initial position I start to raise the mounts I theins 44 and 45, over which {products, for example insulator pins, are located. ; Pa vibration position (Fig. 4), conditionally; It is assumed that the shroud is put on the glass part of the lifting bracket 44 (taking into account the vibration of the whole mechanism) compacts the cement-sand mixture and sends the cap to the required position on the glass; When the bracket 44 is raised, the rotary face 49 acts on a lever with a roller 50: the shutters 47 are closed, and the rubber half rings 48 isolate the nipple cavity from moisture and determine the final fitting of the nipple on the glass part.

I When lifting the arm 44, raises the rail 34, which through the gear-unit; the nude 51 lowers the rail 32 and with it a bracket 36 with a crosspiece 38 and a cop: rest 40. Lowering, the crosspiece 38 centers the glass, and tapered stop {centers and presses the rod into the head filled with cement-sand mixture with teklodetal and. At an angle of 15 - 20 ° to a maximum cam lift, the guide

The fake 32 acts on the valve 52, which supplies water to the nozzles of the petals 47, flushing the face of the cement-sand mixture from the outer surface of the socket.

At the position of the assembly, the cam 28 (Fig. 5) at the moment of the initial initial position begins to lift the brace 45 with the self-tightening knot 21, over which the cap hangs in the gripping rails 62. Lifting in the self-tightening unit 21, the knob grips 23 is centered and extends out of the gripping rails 62, and is subsequently put on the head of the glass part that is held by the grips 9.

Lift, guide rail 35 through gear unit 51 lowers rail 33 with bracket 37, crosspiece 39, and pneumatic cylinder 41. At the time the guides 42 coincide with the guides of the accumulator 43, in the latter the shutter is triggered rod, ramps

rolling along the guide 42 into the stem of the pneumatic cylinder 41. At this point, the rail 33 acts on the valve 53, by which air is supplied to the cavity of the cylinder 41 (to clamp the rod head and its centering). Then, lowering the cross, the spider 39 centers the glass detail. Upon further lowering of the bracket 37, the springs of the cross-piece 39 are compressed, and the rod is pressed by the pneumatic cylinder 41 into the cement-sand mixture into the head of the glass part. The vibration of the mechanism helps to condense this mass.

The stroke of the cam 28 and pneumatic cylinder 41 is designed for not a complete assembly of the finished insulator, but a preliminary one, taking into account that in the process of transferring the insulator the folder does not jump off the glass part head. The amount of movement of the upper and lower elements in the assembly and vibration mechanisms is governed by the position of the adjustable roller 46 and the movement of the arm 37 on the rail 33. The idle angle of the cams 27 and 28 (when the roller 46 does not rise from the cam profile) is equal to half the angle of the sector of incomplete gear 74 (when the carriage 3 moves forward).

When the gear 74 engages the gear 75, the latter unlocks from the latch 83 and begins to rotate the shaft 76 with the cam 81, which acts on the roller of the lever 20. Finally, the lifting frame 15 rises through the grip 19 and the levers 14, and with it the frame 17. Since the gap between the roller 8 of the slider 7 and the lower plane of the frame 17 is larger than the gap between the lower plane of the products and the saddle 22, the self-tightening knots first operate (when exposed to the lower planes of the products on the saddle 22, which, lowering, closes the grips 23 ).

Then, the lower plane of the frame 17 acts on the rollers 8 of the slider 7, which are opened through the levers 6 and the axis 4 of the grip 5, to release the product. This ensures the interception of products during their transfer. As the cam 81 rotates further, its convex part keeps the lifting frame 15 with the items in a raised position.

At the positions of the assembly and vibration of the product, they are held in the upper position due to the profiles of the cams 27 and 28. After the frame 15 is fully raised from the positions of the finished product storage device, the device like an industrial robot removes the finished products and installs them in a subsequent machine, for example, in an insulator drying oven. or in a packing machine.

At the beginning of the initial position, crankshaft-82 82 does not reach the dead center of the connecting rods II, although cart 3 has stopped, until it stops 12. It is dead

The crank rotation zone at a certain angle is equal to the angle of rotation of the cam profile 81 acting on the lever 20, with which the lifting frame 15 rises, which ensures the centering of the vertical axes of the self-tightening and gripping units during the transfer of products from the gripping units to the self-tightening units.

Vrash, and cf, the shaft 76 rotates the crankshaft 81, with which the trolley 3 is rolled back through the cranks 11. At the end of the movement of the carriage 3 back, the latter rests again in the same rear stop 12, the centering vertical axes of the self-tightening and gripping units. At this moment, the latch 7 unlocks the latch 18 and the frame 17, descending from its own weight, acts on the rollers 8 of the ram 7, which rotate the lever 6 and the grip 5 fixed on the axis 4. This ensures the closing of the gripping units, which hold the product on positions of assembly and vibration of products. Extreme grabs 5 through grades 10 rotate grabs 9, gripping the glass part at the position of the accumulator 78 glass parts, where during this period the rotating shaft of the gearbox 73 with a roller lever 77 raises the area of the accumulator 78 of the glass parts and with it the glass part.

Then, the roller of the lever 20 escapes from the cam 81, lowering the lifting frame 15. The lever 77 during this period escapes from the platform of the accumulator 78, which together with the self-tightening device descends to its original position. When lowering the lifting frame 15, the rollers 8 of the slider 7 act on the upper plane of the frame 17 and lift it, after which it is fixed by the latch 18.

With further rotation of the gear 74 by the crank 82 with the connecting rod 20, the carriage 3 moves forward, and in its gripping units the products are transferred from the initial positions to the next ones. At the end of the turn, when the gear 74 escapes from the gear 75, the carriage 3 is reset. The cycle is repeated.

Since the cap feeder through a pair of rails 54 and 55 in contact with gear unit 57 is connected to the carriage 3, the movement of the slider 56, which is rigidly connected to the rail 55, occurs simultaneously, with the difference that the slider 56 moves at an angle to moving carts 3.

Since the lever 20 with a flexible rod 69 or an angular lever with a rod is connected to the levers 65 and 66 of the lifting frame 64, it is raised and lowered together with the lifting and lowering of the lifting frame 15. It follows that the opening and closing of the self-tightening and gripping The nodes of the cap transfer mechanism occur in the same way as on the central gear of product transfer. Other mechanisms for transferring products to other positions can also be attached to the central mechanism for the transfer of products, i.e., it can be assembled or assembled by means of aggregation.
