SU1627365A1 - Method for orientation of cylindrical slotted-end parts - Google Patents

Abstract

The invention relates to mechanical engineering and can be used to automate the processes of loading and assembly. The aim of the invention is to increase the reliability of operation by reducing the number of power effects on the part during orientation. A cylindrical part with a groove on the end surface is fed into the orientation zone along the supply tray 1 and is subjected to a flat-shaped compressed air jet (nozzle 3 in the form of a slit), directed normally to the said end surface. At the same time, the part is lifted by an air cushion formed by an additional stream of compressed air directed from below and flowing out of the nozzle 4. As a result of these power effects and the interaction of the flow of compressed air from the flat nozzle with the groove of the piece, the latter takes the position at which the groove and the flat nozzle 3 are perpendicular. In the specified oriented position, the part is fed to the loading or assembly area. 1 hp ff, 5 ill. (L

Description

1

The invention relates to mechanical engineering and can be used to automate the processes of loading and assembly.

The purpose of the invention is to increase the reliability and orientation by reducing the number (. Of the impact on the part

On flash 1 shows a device that implements the specified method of orientation of the part, a general view; Figs 2, 3 illustrate the distribution of force effects on a part during the orientation process, on flash 4 an embodiment of the device for orienting a part with a through hole; Fig 5 - section a a in fig 4

The method of orientation of cylindrical parts with a groove on the end surface includes transporting the part along the feeding tray 1 up to the stop 2 and exposing the part to a jet of compressed air having a flat shape (nozzle 3 in the form of a slit) and directed normally to the yurts surface with the groove from Bottom to (Fig. 1), an additional jet of compressed air emanating from the nozzle 4 is applied. to create an air PILLOW As a result of these power effects, a pair of forces P occurs, causing the moment M due to contact of the air flow (moving kasatachno loverhnoii end face) with a groove, and the item razvorachi

around its longitudinal axis and occupies a position in which the groove on the end surface of the part is located perpendicular to the flat jet of compressed air (Fig. 3). After that, the part is removed from the orientation zone.

When the parts with a groove on the end surface and a through hole along the longitudinal axis are oriented, there is no need to exert an additional jet of compressed air from below. The airbag is created by the pressure of the compressed air of the flat jet flowing through the part through to the atmosphere (Fig. 4 and 5).

Claims (1)

Invention Formula  The method of orientation of cylindrical parts with a groove on the end surface consists in acting on the part with a jet of compressed air from the groove on the end surface, characterized in that, in order to increase the reliability of orientation, the stream of compressed air is given a flat shape and is guided normally to the end surface. groove 2 The method according to claim 1, characterized in that the part is subjected to an additional jet of compressed air to create an air cushion.
