Abstract

The invention relates to machine tools, mainly to the loading equipment for machine tools, and is intended for automatic installation directly into the machine chuck of workpieces such as stepped sleeves, rollers, fittings, i.e. cylindrical workpieces with areas of different diameters. The aim of the invention is to enhance the functionality of the boot device by feeding oriented parts. The workpiece 11 is fed from the feed chute 1. The part may fall into the cavity of the sleeve 3 down with a smaller diameter or up with a smaller diameter. In the first case, the part falls into the groove 10. Then the rammer 5, moving from the actuator 6, releases the sleeve 7. The sleeve 7, moving from the spring 8, hits the bottom of the part 11 and turns it counterclockwise. Then the rammer 5 pushes the part 11 into the outlet of the sleeve 3, while simultaneously moving it to the left. The part is clamped in the chuck of the machine. After that, the rammer 5 with the sleeve is returned to its original position. If the part falls into the cavity of the sleeve 3 upwards with a smaller diameter, it does not fall into the groove 10 and the sleeve 7 hits the top of the part, turning it counterclockwise. Thus, the part is always projected with a smaller diameter forward. 5 il. with S C / s

FIG.

The invention relates to machine tools, mainly to the loading equipment for machine tools, and is intended for automatic installation directly into the machine cartridge of workpieces such as stepped sleeves, rollers, fittings, etc., i.e., cylindrical workpieces with areas of different diameters.

The purpose of the invention is to enhance the functionality of the boot device by providing orientation of the part during transport. FIG. 1 shows the boot device in the initial position, a general view in section; in fig. 2 - the same at the moment of orientation of the part; in fig. 3 - the same in the final position; in fig. 4 shows section A-A in FIG. one; in fig. 5 is a section BB in FIG. .

The loading device contains a feeding tray 1, rigidly fixed to the 1m outboard of the tray 2, inside which is installed the sleeve 3, the guide sleeve 4 and the dispatcher 5 with the drive 6. On the distribution unit 5 between the sleeve 3 and the sleeve 4 coaxially: mounted the orienting element, for example, in the form of a sleeve 7, is spring-loaded; with respect to the sleeve 3 by the spring 8. The last-: ice is placed in the sleeve 3. In the guide sleeve 4 and the sleeve 3, two grooves 9 and 10 are made, coociibie the loading tray and located on diametrically opposite sides of the sleeve and sleeve. In this case, the groove 9 is intended for cutting a piece 11 such as a stepped roller or a sleeve from the feed tray; into the cavity of the sleeve 3, and the additional groove 10 is the installation place for the piece 11. This slot has a width corresponding to a smaller diameter of the end of the piece. In the end part of the boot device is installed rigidly connected to the sleeve 3, the tip 12, which has an internal conical surface, and the rammer 5 is made in the form of a cylinder with a conical working part.

The boot device operates as follows.

In the initial position, the rammer 5 with the orienting element L - sleeve 7 is in the extreme right position, the spring 8 is compressed, the grooves 9 and 10 of the sleeve 3 are free and aligned with the outlet of the feed tray I.

A command is issued to a cutter (not shown), which passes one piece AND an arbitrary end down from the feed tray 1 through the groove 9 into the cavity of the sleeve. In this case, two situations arise - the part falls down with the end of a smaller diameter and the child falls down with a section of a larger diameter. In the first case, the part, the passage through the cavity of the sleeve, is installed in the groove 10 and "hangs in it on the shoulders formed by the difference in diameter 5

ditch of their plots. A command is received to the actuator 6, and the rammer 5 is moved to the left. In this case, the orienting element is released - the sleeve 7, which, under the action of the expanding pre-compressed spring 8, also moves to the left in the annular cavity formed between the sleeve 3 and the sleeve 4, before meeting and contacting the part P.

0 of the lower part of the sleeve 7 with a part of a smaller diameter of the part “stuck in the groove 10. With further movement, the rammer 5 and the sleeve 7 last act on the specified end and unfold the part II

 clockwise, simultaneously withdrawing it from the groove into the longitudinal cavity of the sleeve (FIG. 2). The spring 8 is decompressed and stops along with the orienting sleeve 7, while moving the rammer, I’ll act on the already oriented smaller end

0 forward the part, advances it to the end face of the tip 12 to the position required for further installation of the part 11 into the machine cartridge. The part is locked with a retainer (not shown). A rammer having a tapered surface corresponding to the inner conical surface of the tip 12 is aligned with this surface, and further movement of the pusher leads to the movement of the entire assembly containing the sleeve 3, sleeve 4, tip 12 with the fixed part I, to the machine chuck. After the part is fixed in the cartridge, it is unmounted and compressed air is fed into the brush cavity of the actuator 6. The grouper 5 moves to the right along with the sleeve 3 to its original position. The cycle is over.

In the case when from tray u, its tray part 1 I gets into the sleeve section of a larger diameter downwards, installation also takes place in groove 10, but since this groove is smaller than the specified section, the part does not enter and does not enter falls into the groove, and is placed completely over} {them, with the end of a smaller diameter in the upper part. When moving rammer 5 left contact

From the sleeve 7, with the end of a smaller diameter, it is carried out in the upper part and the part is tilted counterclockwise, being mounted in the longitudinal cavity of the sleeve with the area of smaller diameter forward. Further movement of the part occurs in the same way as above.
