Abstract

The invention can be used when sorting cylindrical rollers. This device improves performance. The principle of operation is that the crank mechanism is located on the main frame of the device, the movement of which causes the movement of the pedometer arm, which turns the ratchet wheel fixedly connected to the delivery circle. The movement of the pedometric lever causes, through further traction and two levers, the movement of the needle holder, which from the nests of the delivery circle protrudes the measured cylindrical rollers into a prismatic support. A cylindrical roller is located above the prismatic support and the first and second measuring tips are in a radical direction to the cylindrical roller being measured. Measuring tips are fixed in moving parts of two planetary parallelograms. The movable part of the first planetary parallelogram is connected to a sensor, the sensitive element of which is in contact with a set screw on the movable part of the second planetary parallelogram. Through the sensor, the mechanical part of the device is connected to the electrical part, which consists of a computing unit connected to the control unit and the sorting mechanism. The device is equipped with a friction brake. 2 Il.

At the end of the crank 6 of the drive engine attached connecting rod 7, which is equipped with the first 14 and the second 15 scenes. Between the wings 14, 15 are located the first 12 and the second lock spring 13. The carriage 8, with which the lock micro-closure device 11 is fixedly connected, the sensor of which is in contact with the protrusion 10, is made on the surface of the connecting rod 7. At the bottom of the carriage 8 hinge

by means of which the carriage 8 is connected to the rocker arm 5 rotating around the axis of rotation of the ratchet wheel

4. The rocker arm 5 is provided at the end with a pawl 9, dropping into the tooth of the ratchet wheel 4. Outside the ratchet wheel axis 4, the axially movable holder 16 of the ejector 20 is connected to the arm 5 by means of a hinge mechanism consisting of 17 and arms 18, 19, arranged rotatably on the main frame 1. Ejector 20

mounted against a prismatic support 21 for mounting a measurable cylindrical roller, above which roller 22} is located, in contact with its perimeter, with a measurable cylindrical roller. The roller 22 is connected to a drive mechanism located in a drive hub 24 connected by means of a drive lever 25 to an axial cam 26 on crank 60

In the radial direction to the surface of the cylindrical roller being measured, the first 29 and second 30 measuring tips are located opposite each other. Measuring tips 29, 30 are fixed in the moving parts of the first 31 and second 32 planetary parallelograms, the fixed parts of which are connected to the main frame 1. The sensing element of the sensor 33 fixed in the movable part of the first planetary parallelogram 31 rests with the tip on the contact contact of the set screw 34 on the movable part of the second planetary parallelogram 32. By means of the sensor 33 the mechanical part of the device is connected to its electrical part consisting of a computing unit 35 connected to the control block 37 and the sorting mechanism 36, to the block 37 is attached a friction brake consisting on one side of a pulley 38 located on the shaft together with a drum Anom 3, ratchet wheel 4 and the yoke 5, on the other hand - from friction tape 39, one end of which is attached to the main frame 1 directly, and the other through a spring 40 on the holder 41.

5 The principle of operation of the device is as follows.

Before measuring, the device is set to the required value,

That between the measuring tips 29, 30 enter the reference cylindrical roller "Tip of the sensing element of the sensor 33 and, therefore, the position of the arrow of the panel measuring device of the computing unit 35 is set with a screw 34". At the beginning of the measuring cycle, the drum 3 is rotated by the rocker arm 5 on the ratchet 4 one step between adjacent slots along its perimeter, the ejector 20, whose movement is caused by the movement of the rocker arm 5, inserts the measured cylindrical roller from the pocket into the an isometric support 21. The roller 22 is thus deflected from the prismatic support 21 by the action of the actuator lever 25, the movement of which is caused by the movement of the axial cam 26. After inserting the measured cylindrical roller into the prismatic support 21, the roller 22 is fed to the measured cylindrical roller and rotating from the drive mechanism 23 feeds a rotating measurable cylindrical roller with an end to an ejector tip

20, which thus serves as a stop. The diameter or ovality of the cylindrical roller to be measured is transmitted to measuring tips 29, 30 and then to sensor 33, from where the electrical signal is supplied to computing unit 35, control block 37 and sorting mechanism 36. Here cylindrical rollers are sorted according to the size of average diameter or ovality into corresponding groups.

To prevent damage to the mechanism and the drive motor, there is a fuse consisting of a lock 10 on the connecting rod 7 and a lock micro-plug 11 attached to the carriage 8. The carriage 8 is held on the connecting rod 7 of the crank-connecting mechanism in the central position by locking springs 12, 13, which rests on the wings 14, 15. If the ratchet wheel 4 locks up, the movement of the rocker arm 5 connected by a hinge to the carriage 8 also stops. However, the connecting rod 7 continues to move relative to the stationary Roethke 8 caused by the driving mechanism, The result is chrez0

dimensional compression of one of the locking springs 12, 13 and the movement of the microblock sensor 11 of the locking outside the protrusion 10. The drive motor is disconnected from the source of electrical energy.

To limit the movement of parts of the mechanism caused by inertia, the device is equipped with a friction brake consisting of a pulley 38 wrapped with friction tape 39. The tension of the friction tape 39 and, consequently, the braking force 5 is adjusted by a spring 40 fixed in the holder 41 moved relative to main frame 1 device,

The device according to the invention is advantageously used in the bearing industry to control the diameter and ovality of the precise cylindrical rollers of roller bearings.

The invention will provide improved performance.
