Abstract

The invention relates to machine-assembly production and can be used, for example, for assembling connecting rods with pistons by installing pins in coaxial holes of these parts. The purpose of the invention is to improve the quality of the assembly by eliminating the possibility of damage to the mating surfaces. The connecting rod, piston 7 and pin 6 are placed in the cradle, after which the centering rod 14 extends through the openings of the female parts and presses pin 6 to the pushing rod 13. The latter moves the pin 6 out. the rotation is transmitted to the slider 18 with the eccentric striker 19 placed inside the rod 13. Due to the rolling of the rollers on the slider, a pulsating load is transmitted to the slider 18 by the copier 18, which the hammer head 19 transmits to different locations of the finger end 6 Analog The rotational-impact mechanism is also installed in the centering rod 14. 2 Cp f-ly, 8 ill.

Claims (2)

Claim 1 o Assembly device containing mounted on the basis of the feeding mechanisms of the assembled parts, lodges for these parts, as well as a mechanism for installing and 'centering the covered part with pushing and centering rods located coaxially and opposite to one another, with the drives, characterized in that, in order to improve the quality of the collection. ki by eliminating damage to the mating surfaces, it is equipped with a ^J mechanism of rotary-impact action on the end face of the covered part, the push rod is hollow, and the mechanism of rotational-shock cart, θ action is made in the form of a slider with an eccentric fastened on its end facing the lodgements, the striker , 'and a diametrical through hole at the opposite end of the push rod installed in the cavity coaxially with the latter with the possibility of axial reciprocating movement and rotation and axial relative to the 2Q rod of the copier mounted on the end face of the pushing rod facing the drive of its translational movement, axis fixed in the hole of the slide, rollers mounted 25 at the ends of the axis with the possibility of free rotation and interaction with the copier, as well as a slider rotation drive. 2. The device according to claim 1, characterized in that it is equipped with an additional mechanism of rotational-impact action, made similar to the main one and installed opposite to the latter, the centering rod is hollow, and 35 slider additional mechanism is located in the centering rod. The device according to claims 1 and 2, characterized in that the lodgements for the covering parts are installed, are updated with the possibility of adjusting movement in the direction perpendicular to the axis of the assembly, and are spring-loaded relative to the base.
