Description

one

The invention relates to loading devices for feeding parts into a machine and can be used, for example, for loading multi-spindle semi-automatic machines.

A charging device of the type of rotating bodies with a tray, a guide bushing and a feed collet coaxially with a spindle is known.

The aim of the invention is to simplify the design of the boot device.

This is achieved in that the feed collet is provided with a cut-out for pushing the workpiece into it and is rotatable around its axis. This ensures the simultaneous cutting off of the regular part and its supply to the clamping mechanism of the machine.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a view along arrow B in FIG. one.

The device consists of a guide sleeve 1 (see Fig. 1) and a carrier sleeve 2 in which the collet 3 is placed in the internal cavities, rigidly fastened to the shank 4, which contains a pusher 5. On

the threaded part of the carrier sleeve 2 by means of a lock nut 6 is fixed groove packaged equalizer sleeve 7, in the grooves of which (see FIG. 3) two diametrically arranged and secured pins 8 fixed in the shank 4 are enclosed into the collet 3; 10. A switch of the end system of the electrohydraulic is attached to the tray 9 and comes in contact with the stop 11 mounted on the mechanical part of the machine 12 containing the clamping mechanism 13. The device operates as follows. On the supply tray 9 continuously serves parts 10.

. Thus, in the initial position of the device, the collet 3 is always loaded with one piece, where the latter goes through the boot piece. Stop 11, mounted on the mechanical part of the machine 12, acts on the limit switch. The latter is connected with an electro-hydraulic system, which drives the shank 4 and the collet 3, which is rigidly connected with it, when the shank 4 moves to the left side.

using the driven fingers 8 and the slotted control sleeve 7 (see Fig. 3), simultaneously rotate around their longitudinal axis in a clockwise direction (see Fig. 2). By virtue of what, a regular part is cut off and pre-fed into the zone of action of the clamping mechanism 13 of the machine .12. When right-cutting grooves (see Fig. C) the angle of elevation of the helix provides self-unscrewing. The movement in the guide sleeve 1 of the collet 3, unclench the surface of the section ab, which assumes a position parallel to the axis of the collet. At this moment, the electro-hydraulic system actuates the pusher 5; Using a pusher, the detail U is advanced to the left into the centering section, centered, and fed into the clamping mechanism 13 of the machine 12 until it stops. By means of an electro-hydraulic device, such as a pressure switch, the device is reset. Snga 3 has a cone-shaped bbs surface, ensuring a clear fixation and subsequent correct direction of the part to the centering section a-b when exposed to the pusher 5, as well as preventing the part from accidentally falling out of the centering section when the pusher 5 is in the starting position.
