(54) MACHINE FOR STRAINING. BEARINGS The invention relates to the field of mechanical and assembly work, in particular to equipment for pressing the inner bearing cages onto the axle from two sides. A known machine for pressing bearings on both sides, containing power cylinders mounted on a frame coaxially opposite one another, feeders of assembled parts and a mechanism for supplying and installing the p. However, such a machine does not separate the outer sleeves of bearings from the inner ones and press the latter onto the axle. elimination of this pressure gauge in the machine for pressing in bearings on both sides, containing power heads mounted on the bed coaxially one against the power heads, feeders of assembled parts and feed and positioning mechanism and these parts, the latter is made in the form of vertically moving the carriage along the guides on the body of the carriage mechanism with profiled grooves on some side e walls and limiters on others, as well as a spring-loaded cutter with an emphasis interacting with the carriage, and rocker arms with rigidly fixed .EN WITH TWO PARTIES

Figure 1 presents the machine, a general view; figure 2 - section aa in figure 1; Fig, 3 - machine, top view. The press contains power heads 2 mounted on frame 1 coaxially one against the other, a feeder 3 of assembled parts and a mechanism for feeding parts and installing in an assembly zone, which is made in the form of a carriage 4 having grooves b and 7 on one side walls 5; limiters 8 on other brands. Prisms 9 are placed on the carriage. The carriage 4 is mounted for movement along the guides of the housing 10 from the actuator in the form of a power cylinder 11, the cutter 12 with clamps 13 and the stop 14 mounted on rolling pins 15 and spring-loaded 16 with respect to the housing 10. On the rocker arm 17, the pushers 18 are rigidly fixed, spring loaded 19 relative to the airspace 10, the pushers 18 are in constant contact with the surface 20 of the walls of the carriage 4, the cutter 12 with the locking pins 13 and the yoke 17 with the pushers 18 provide the axles 21 and the bearings to the assembly area, the drilling zone. The grooves 6 and 7 and the stops 8 of the carriage 4 ensure the separation of the bearing sleeves and the dispensing of the outer sleeves. Power heads 2 consist of centering CYLINDERS 22 with centering rods 23 and press-in cylinders 24 with pressing rods 25. The machine works as follows: Carriage 4 with prisms 9 moves; the ram 11 along the guides of the housing 10 to the extreme upper position. When the carriage 4 is moved upwards, the junction box 12 with clamps 13 rises up under the action of the spring 16 and the clamps 13 cut off the subsequent assembled parts (two bearings and an axis) located on the receiving trays 26 and 27 of the feeder 3. In the upper position, the carriage 4 with surface 20 presses Two pushers 18, which lift the rocker 1 up from four of the same pushers that lift it up to the top position, release the two bearings and axis 21. Axle 21 rolls onto prisms 9, And bearings roll onto slats 28 fixedly mounted on sides ste Kah housing 10 to limiters 8 Single Roethke 4. Then triggered centering conductive cylinders 22. Synchronously converge dowel rods 23, they pass inside the inner yokes bearing is centered and rigidly fixed axis 21 zadannsad position. With this, the side walls 5 of the carriage 4 keep the inner bearing cages from moving. After centering the axis 21, the carriage 4 with the prisms 9 is lowered down. Together with it, under the spring 19, lower the rocker 17 with the pullers 18, which in the lowest position prevent the assembled parts from collapsing into the press-in area. When moving carriages} {and 4 down, she presses the stop 14 and moves the slam-shut 12 along the rolling pins 15 down. The clips 13 lower with the slam 12 and release the assembled parts, the kOTOpue roll down the trays 2 and 27 and rest against the pushers 18. When the carriage 4 reaches the lowest position, the pressing cylinders 24 turn on, the pressing rods 25 come together, pick up the inner race of the bearings and they are pressed onto the axle 21. In this case, the outer bearing cages are held by the side walls 5 of the carriage 4 and hang on the pressing rods 25. After the pressing is completed, the centering rods 23 and the pressing rods 25 are consumed and release the assembly to be assembled, which rolls along the chute 28 and releases the outer rings of the bearings, which roll off the sloped surfaces of the slats 29 and the chutes 30. At the same time, the carriages 4-with the stops 8 are in the lower position and the stops 8 do not prevent the rolls outer bearing sleeves. The cycle is over. A new cycle starts with lifting the carriage 4. The machine has a simple structure, high performance, is easy to maintain, and is reliable in operation. Formula of the invention The machine for pressing in bearings from two sides, containing power heads mounted coaxially against the other, powering the assembled parts and the feed and installation mechanism, in order to ensure that the outer bearing sleeves are separated from the inner ones and pressed on the axis, the feed and installation mechanism is designed as a vertically moving carriage along the rails on the casing of the carriage mechanism with shaped grooves on one side of its estimates and limiters on others, and a spring loaded stripper with clamps and the stop interacting with the carriage and rigidly fixed to the rocker at its kontsoos jacks, spring-loaded against the housing and in contact with the walls of the carriage.
