Description

one

 The invention relates to the field of instrumentation and electronic equipment and can be used in the orienting of parts with flats on shoulders and a slight displacement of the center of gravity, for example, contact pairs of electrical connectors.

A device is known for the orientation of parts supplied along a tray to: a stop beveled at an angle to the direction of movement of the parts and forming a window with the end of the tray to lock the parts tl.

However, such a device is intended only for the orientation of parts with clearly expressed signs, for example, a mixture of gravity centers.

The aim of the invention is to provide orientation of the stepped parts with flats on the shoulders and a slightly displaced center of gravity.

This is achieved by the fact that the proposed device is equipped with an inclined platform placed under the abutment.

which is angled to the direction of movement of the parts and forms an acute angle with the butt of the stop, and the end portion of the tray is made with a groove whose width and depth correspond to the diameter of the thin part of the part.

FIG. 1 schematically shows a device for orientation of parts, side view; in fig. 2 - the same, section A-A; in fig. 3, 4, 5 shows the possible positions of the part during orientation; in fig. 6 is a view along arrow B in FIG. one; in fig. 7 is a section bb of FIG. 6

The device for orientation of the parts comprises a tray 1 in which a groove 2 is made with a width and depth corresponding to the diameter of the thin part of the part, in this case the diameter of the shank, an inclined platform 3 with a support 4 fixed on it. Between the end of the tray 1 and platform 3 with an emphasis 4 a window 5 is made. The platform 3 is inclined and the stop 4 is more than an angle BE in the direction of movement of the part, moreover, the stop 4 is offset from

of the inclined platform 3 and fixed on it in such a way that its end face forms an acute angle with the TOpuoiA inclined platform. The inclined platform 3 and the stop 4 are installed with the ability to move in the direction of movement of the parts due to mounting screws 6 and oval holes 7. The minimum size of the window 5 is in the plan of the smaller size of the part, it is located in the direction of movement of the part, and the window of the maximum size is angled to the direction of movement of the parts and more. the details.

The device works as follows.

Part 8, moving with the tray 1 and the groove 2 with the tail (heavy) or contact (light) part, in both, has two positions - the faces are perpendicular to the walls of the tray or parallel to them. In any of the four positions, the contact part is raised, and the tail is inclined and slides along the bottom of groove 2. Part 8, moving with a hard end forward (tail part), reaches the edge of tray 1, gradually descends, falls into window 5 and falls into discharge tray (not shown). Item 8, moving forward with the contact part, passes through the shelf and the contact part enters the inclined platform. Under influence

the stop 4, installed at an angle, the part is turned, moves along the inclined platform 3 until the tail part falls into the window 5. Thus, all the parts fall into the discharge tray with the heavy end (shank) down.
