Abstract

Usage: in the repair industry and for the maintenance of internal combustion engines. SUBSTANCE: to expand operational capabilities, the grippers are made in the form of rods and placed in the holes of the cage with the possibility of reciprocating movement, and the hooks are made in the form of elastic plates and are fixed at the ends of at least two rods. 2 ill.

Description

The invention relates to repair production and may find application for removing hollow parts from a housing, for example a sleeve from a housing of an internal combustion engine.

The purpose of the invention is the expansion of operational capabilities.

This goal is achieved in that in the device for extracting hollow parts from the housing containing the power element, a radial displacement drive, a cage with radial holes, grips with hooks, and the grippers are placed in the holes of the cage with the possibility of reciprocating movement, and the radial drive the movement is connected with the power element and is installed with the possibility of acting on the grips, the grippers are made in the form of rods, and the hooks are made in the form of elastic plates and are fixed at the ends of at least two rods her.

In FIG. 1 shows a device for removing hollow parts from a housing, a vertical section; in FIG. 2 is a section AA in FIG. 1.

The device for extracting hollow parts from the housing contains a holder 1 with radial holes 2, in which, with the possibility of reciprocating movement, grippers 3 are placed in the form of rods, on the outer ends of which hooks 5 are fixed in the form of elastic plates with hinges 4. Each hook is attached to the ends of at least two rods.

The grippers 3 with the hooks 5 are provided with a radial displacement drive 6 made in the form of a truncated cone with an axial hole 7 in a small base. The conical surface of the actuator 6 interacts with the ends of the grippers 3.

The device is equipped with a power element 8, made in the form of a screw, the threaded surface of which is placed in the threaded hole 9 of the holder 1, and one of its ends is rotatably and fixed from axial movement in the hole 7 of the actuator 6, the other end of the power element is equipped with a gate 10.

The device operates as follows.

In order to remove the hollow part from the housing, for example, the sleeve from the internal combustion engine housing, it is necessary to move the engine piston 11 to its lowest position, first removing the block head from the housing, lower the device into the sleeve bore 12, placing it with the large base of the drive cone b on the piston. In this case, the force element 8 is placed on the central axis of the hole, the grippers 3 are radially, and the hooks 5 are on the inner side of the sleeve 12.

Holding the device by the clip 1, rotate the power element 8 by the collar 10, twisting it from the threaded hole 9 of the clip. With this rotation, the element 8 will move upward relative to the cage together with the drive 6, which, acting on the end faces of the grippers 3 with a conical surface, moves them in the radial holes 2 of the cage towards the sleeve 12 and presses the hooks 5 against the inside of the sleeve 12 with force. in this case, hooks made in the form of elastic plates bend around the surface of the sleeve along an arc of a circle, increasing the adhesion force of the contacting surfaces.

Manually rotate the crankshaft of the engine (not shown), which

through the connecting rod 13, the piston 11 moves upward together with the device and the sleeve 12 placed on it, sliding it out of the hole in the engine housing 14.

In the same way, shells of a different size are removed from the housing, as well as other hollow parts.

The implementation of grips in the form of rods and hooks in the form of elastic plates expands the operational capabilities of the device and with its help hollow parts of different sizes can be removed from the housings.

Claims (1)
