Description

(54) ORIENTING DEVICE

The invention relates to mechanical engineering and can be used when loading parts with different configuration of the ends of machine tools and assembly machines.

A device is known for supplying parts with different configurations of ends, containing a feed tray with a non-magnetic contact plate for controlling an electromagnet for resetting parts into the discharge tray l.

However, this device is structurally difficult and applicable for the orientation of parts with a difference in the size of surfaces up to 1 mm.

It is also known a device for orientation of parts, comprising an electromagnet with a rotatable non-magnetic plate on the core, inlet and outlet trays 2.

A disadvantage of the known device is the limited scope of application for orientation of parts with a ratio of overall dimensions close to one and different configuration of the ends.

The purpose of the invention is to expand the technological capabilities of the device.

This goal is achieved by the fact that the non-magnetic plate is fixed to the core fixedly and a groove is made on it, the width of which is smaller than the largest diameter of the oriented part.

FIG. 1 shows a device, a general view of FIG. 2 - view at the orientation of the part, going blunt end; in fig. 3 is a view with the orientation of the part reaching the sharp end.

The orienting device includes an electromagnet 1, a non-magnetic fixed plate 2 with a groove 3, a base 5 driving tray 4, a discharge tray 5 and 6, a pivot bearing 7, a spring B, a rod 9, an actuator 10, a limit switch 11, a vibrator silo 12.

20 The device operates as follows.

The parts along the feed chute 4 of the vibrating hopper 12 are moved to the pivot bearing 7.

Depending on the configuration of the end, the part, when fed with the blunt end forward, abuts against a fixed non-magnetic plate (Fig. 2), remains lying on the rotary plate, 30 is not attracted by an electromagnet, or.

the tip of the west into the groove 3, is attracted by it (FIG. 3),

In the first case, when the rod 9 with the electromagnet 1 is moved into the zone of the outgoing trays 5 and 6, the rotary support .7, resting against the fixed stop, is demagnetized and resets the detunner into the outlet 11 | and {1 tray 5 (Fig. 2)

In the second case, the part is transferred and reset to the discharge chute b, after the electromagnet 1 has been tilted by the limit switch 11. The pivot bearing 7 returns to its initial position under the action of the spring 8 when the rod 9 with the electromagnet 1 is fed from the actuator 10 to the zone of the supply tray 4 The feed cycle is then repeated.

The proposed design of the device makes it possible to increase the reliability of its operation when orienting parts with a variable configuration of torirov.
