Description

I

The invention relates to the field of engineering and can be used. it is called when mounting cases of cars.

A device is known for fixing the machine housings on a frame or a facial fastener in order to preserve centering, consisting of control pins that are tightly stored in holes in the frame and feet of the arms C11.

A disadvantage of the known device is the need for subsequent alignments to drill and deploy new holes with a hand-held tool in place. Such work is laborious and often difficult for the lack of CBo6oivno places in the paw of the case.

It is also known to connect the paw of the coil of the machine with the base with a pin, the shank of which is pressed into the base, and the guide part is loosely installed into the opening of the paw into the gap between the wall of the hole and

the outer surface of the pin is filled with compound C 23.

This compound is closest to the invention in terms of technical dryness and the achieved result.

During operation of rotating machines, for example, compressor installations consisting of compresor cases, engine, multiplier, there is a need for re-alignment due to removal of centering, repairs made, etc., after which the cases should be fixed in their new position or fsgndaite.

five

The known compound does not solve the problem of fixing the hulls in a new position without drilling new holes, because after filling with a compound

0 The gaps between the hole in the upper part and the sleeve, having uneven or even threaded surfaces, the sleeve becomes non-separable and made from ONE whole with the porphyry part.

The aim of the invention is to reduce the laboriousness of centering when reassembling.

The set is achieved by the fact that, in the proposed soy and yen, the pin is made with a threaded end located outside the paw of the body and with a shoulder located at the bottom of the hole in the paw, while the wall afterwards has a glacier surface.

FIG. 1 shows the proposed connection, a section; FIG. 2 - the same, but when dismantling.

Pin 1 with its shank 2 is pressed into the hole in the base 3, which may be a base plate or frame. A paw 5 is placed between the paw 4 of the machine body and the base. The hole in the paw is made of a larger diameter than the diameter of the pin 1 in order to be able to provide the required displacement of the machine body during centering. After the centering is completed, the gap between the hole in the body and the pin is filled with a hardening compound, in which hardening plastic can be used, a filler, for example, steel Balls.

With repeated alignments, the hardened compound is dismantled together with pin 1. This is done as follows.

When screwing the threaded end 7 of the pin 1 of the nut 8, (expanding on the sleeve 9, the hardened compound 6 is pulled out of the hole in the liner 4 of the housing together with the pin 1 due to the smooth surface of the hole in the claw of the case.

Since the surface of the hole in the body paw is smooth (done by drilling) and is not prepared (not degreased) before plating the plastic, good adhesion of the compound to the metal does not occur and the force applied to the wrench when screwing on the nuts is enough

for separation of the hardened compound from the walls of the hole.

At the same time, the strength of the hardened compound is sufficient to dismantle it without destruction, although this

The circumstance does not matter, since the hardened compound is not used again and it is removed from the pin with light hammer blows.
