Description

The invention relates to a machine-building system, namely, devices for orienting or sorting rivets, screws, bolts or other parts consisting of a rod and a head, of relatively small dimensions, and can be used in the mechanization of the assembly process of the parts described.

The purpose of the invention is to increase the reliability of the device by ensuring uniform filling of the streams of the vibrating channel.

In Fig. 1. a device is shown, the common vice, in Fig. 2 - view A in Fig. one; in FIG. 3, view B in FIG. 1 in FIG. 4B-B in FIG. one,

The device comprises a base 1, on which in the slots 2 clips 3 with the help of a pressure plate 4 and screws

5 rigidly fixed cylindrical rods 6 with the possibility of changing the center distance.

From the side of oriented parts 7 on cylindrical rods

6, annular grooves 8 are made for the passage of parts into discharge chutes 9.

The base 1 is installed using spring-loaded supports 10 on the rack 11. On the base 1 is fixed a vibrator 12

To ensure reception of parts in fitting 13 of each discharge tray, a funnel 14 is made, and to remove excess and defective parts, bevel 15. On spring-loaded supports 16 there is a plate 17 with a vibrator 18 mounted on it with the possibility of oscillation indicated, the plate is in antiphase oscillation m to the outlet trays 9.

Multi-strand vibrolot.

The plate 17 has cutouts 19 for positioning the cylindrical rods 6 and is positioned relative to them with a small gap.

Vices 19 are increased ho width in order to provide the possibility of adjusting the width of the streams of the vibrating channel by changing the adjustment of the center distance of the rods 6,

The device works as follows.

A batch of parts is fed to a multi-strand vibratory flow, after which vibrators 12 and 18 are turned on, which communicate to the base 1 and the plate 17 at each instant of time opposite in the direction of oscillation.

Parts 7 fall into the streams between the cylindrical rods 6, turn heads upwards and pass under the plate 17. Unoriented and redundant parts interact with the plate 17, are thrown back to it, which increases the likelihood of parts falling into the streams between the cylindrical rods 6.

Having reached the grooves 8, the parts fall into the funnel 14 of the nozzle t3 and further along the discharge chutes 9 to the assembly position. If the trays 9 and the nozzle 13 are filled, then the extra parts along the bevel 15 are removed to the accumulator (not shown), the same happens with defective, for example, bent parts.

To change the device to a different size of parts, loosen the screws 5, move the cylindrical rods 6 to the required distance and fasten the screws 5.

If necessary (for example, when parts with a different head diameter are oriented), the replacement is carried out. The invention allows to significantly simplify the design of the multi-channel vibrating channel, as well as to sort the parts different in terms of both length and diameter.
