Abstract

The invention relates to maintenance equipment. The purpose of the invention is to increase the productivity of the installation and the removal of piston rings. The device contains a guide body 1 with a cassette for a set of piston rings 3, in the radial holes of which spring-loaded retainers of the locking mechanism are located, and an emphasis 2 in which the pusher 9 is located, which interacts with the sensors 8. The device is based on turning on the winding of the electromagnet 4 to create an electromagnetic force that allows for automated removal and installation of piston rings. 2 Il.

The invention relates to mechanical engineering, in particular to repair equipment, and is intended for the repair of internal combustion engines.

The purpose of the invention is to increase the productivity of the installation and to remove the piston rings by making a cassette for a set of ps) negative rings in the form of an annular electromagnet.

FIG. 1 shows the device in position for removing piston rings; in fig. 2 is the same in the position for installing the piston rings.

The device consists of a direction of the housing 1, on which the stop 2 and the cartridge under the set of piston rings 3 with the mechanism of their fixation are fixed. The cassette is made in the form of an annular electromagnet 4 with an inner diameter greater than the nominal diameter of the piston 5 by an amount equal to twice the nominal width of the piston rings. In electri- cal magnet 4, radial holes 6 are also made, in which 111 spring-loaded latches 7 are installed. Mechanism of fixation, made of a diamagnetic-HOIO material.ch.

piston rings fall down toward the base of the right housing 1.

When installing the piston rings, the retainers 7 of the retention mechanism are sprung bounded out of the radial holes 6 to the inner diameter of the electromagnet 4. Each piston ring is mounted on its row of retainers 7. Then the piston is lowered into the directional housing 1, which interacts with its bottom with the pusher 9, which in turn, through interaction with the upper sensor 8, it turns on the winding e: electromagnet 4. The piston rings are magnetically pressed against the inner diameter of the electromagnet 4. When eyshem downward movement of the piston plunger 9 by reacting with a lower sensor 8 turns off the electromagnet winding 4. In this porn1nevye sink in the piston ring groove.

The piston is removed from the device and then the cycle repeats.
