Description

The invention relates to the automation of technological processes in mechanical engineering and can be used in loading devices, where the need for orientation of parts such as studs with different thread pitch at the ends.

The purpose of the invention is to increase the reliability of the device, by

ensure reliable contact spikes

ki with orienting disk.

FIG. 1 shows the device, a general view; figure 2 - section aa in figure 1; on fig.Z - section bb on

1FIG. one .

The device for orientation of threaded parts such as studs 1 contains a mechanism for transporting the studs, embodied in the form of a drum 2, having a drive (not shown), in the receiving part of which two rollers are installed: supporting 3 and supporting 4. Coaxially supporting roller 3 has a reference point 5 in the form of a pointed disk. Depending on the diameter of the orientable stud, the position of the roller 4 is adjusted by the screw 6. The position of the disk 5 in the axial direction is fixed by the screw 7 (Fig. 2). In addition, the device contains a sectional tray consisting of receiving part 8, clamping sectors 9 and outlet part 10. Sectors 9 are reinforced

on the slider 11, the position of which is fixed by the bolt 12. The position of the wall of the receiving part of the tray 8 is adjusted by the bolt 13, and the position of the wall of the output part of the tray 10 is bolt 14. On the output part of the tray 10 is reinforced. a knife 15 (FIG. 3) of a triangular section, the position of which is fixed by a screw 16. The device operates as follows

in a way.

The pin 1 from the receiving part of the tray 8 falls on the rollers 3, 4 and the disk 5 so that one of its ends lies on the roller 3 and the other on the disk 5. When

rotating the drum 2, the pin, pressed by the clamping sectors 9 to the rollers 3 and 4, begins to rotate. The disk 5 engages with the thread windings at the beginning of the pin 1. Subsequently

rotating drum 2, pin 1 moves relative to disk 5. If pin 1 hits the disk 5 with an end with a smaller thread pitch, it will be displaced by a smaller amount. as compared with the amount of pin offset that fell on the disk 5 with an end with a large thread pitch. At the end of the working cycle, the offset pin from the control element falls on the tip

the knife 15 and due to the displacement of its center of gravity expands into the output part of the tray 10 only with an end with a large thread pitch.
