Abstract

The solution relates to a device for orienting bearing cages, especially when punching holes for rollers. The device consists of a feed chute, a switch, a loader, a positioning device and a rotary head. The essence is that the loader is rotatably connected via a pin to a flange provided with radial jaws around the circumference, spring-loaded from the flange. The axial retainers mounted on the rotary head, spring-loaded axially from it, and the stop are connected via a rotatably mounted piston rod to a shaft, a hydraulic cylinder and a transverse hydraulic cylinder via a rotary piston rod connected to a toothed rack pressed on one side by a pulley and connected to gears on the other side.

BACKGROUND OF THE INVENTION The present invention relates to a device for orienting bearing cages, in particular for designated roller bearings.

Doposia! the bearing cages are loaded and orientated in the punching holes of the roller in the eccentric presses by hand. The operation is very physically demanding and the operator is exposed to the risk of injury.

The above-mentioned drawbacks are eliminated by a device consisting of a feed trough, a switch, a tilt, a positioning device and a rotatable head, the essence of which is that the loader is pivotally coupled to the flange provided with radial retainers resilient from the spring flange while the rotating head on which the axial holders are axially spaced from the spring and the stopper, is connected to the shaft, the hydraulic cylinder and the transverse hydraulic cylinder by means of a swivel bearing which is connected to the toothed rack by a pressed roller on one side and connected to the gears on the other.

The invention allows automatic orientation of bearing cages to the stopper position of the loader without operator intervention. Significantly improves the operating conditions of the operator, eliminates the risk of injury to the operator of eccentric presses during cutting. It is also possible to synchronize the movement of the bearing cage orientation device by moving the punching machine - the eccentric press, thereby increasing the punching production.

The bearing cage orientation device comprises a feed trough 18, a switch 24, a rotating head 14, a retainer 15, a stop 16, a spring 27, a dowel 17, a hydraulic cylinder 2, a piston rod 3, a coupling 4, an axial bearing 5, a shaft 6, a transverse hydraulic cylinder 7, rotary piston rod 8, toothed rack 9, gearbox 1, gear wheels 10, 11, 12, sleeve 13, tilt 19, flange 20, jaw 21, spring 22, pulley 26, holder 23, pin 28.

The inlet trough 18 is gravitational, serving the bearing cages 25 before turning the bearing cages 25 in front of the rotating head 14. After the bearing cage 25 is swiveled in front of the rotating head 14, the switch 24 is turned on. By means of the piston rod 3 there is a protrusion 6, which is connected to the extension 3 by a coupling 4 and two axial bearings 5. These bearings 5 allow the shaft 6 to be moved and rotated without the pivoting piston 3 being rotated. The rotary piston 8 is also pulled on the flange 20. At the same time, the transverse hydraulic cylinder 7a is turned by means of a rotary piston 8 which is connected to the toothed rack 9 and rotates the overflow 10, 11, 12. 9 is pressed against the right gear 10 by means of a pulley 26. The second gear 12 is rigidly connected to the housing 13, which rotates the shaft and thus and j rotating head 14o 310 °. When the rotating head 14 is rotated, the bearing cage 25 is slid onto the flange 20 of the actuator 19. Against the accidental rotation of the bearing cage 25 on the flange 20, there are a plurality of jaws 21 which are pushed by the springs 22 onto the inner side of the bearing cage 25. The springs 27 press the bearing cage 25 onto the flange 20. The stop 16 of the pivot head 14 rotates the corresponding hole in the bearing cage 25. When it finds, it snaps into the opening and begins to rotate the cage 25 until the final position. This position can be adjusted to any position of the orientation pin that sits on one of the die heads of the die head. After aligning the bearing cage 25, which remains slid on the flange 20 of the actuator 19, the pivoting head 14 is returned to the downstream position and also rotates to the flood position. Then, the feed of the loader 19 is locked, which pushes the bearing cage 25 towards the punch jaw. He repeats Totosa after blackmailing the entire cage 25.
