Description

(54) DEVICE FOR ASSEMBLING KIDS ALEY

I

The invention can be used, for example, in mechanical engineering and instrument making.

A device for assembling is known comprising a working member with a rotating orienting sleeve, a rotational drive, and also a reciprocating movement actuator 1.

A disadvantage of the known device is low reliability and performance.

The purpose of the invention is to increase the assembly performance and reliability of the device in operation.

For this, in the proposed device, the pneumatic cylinder is provided with an inertial element in the form of an additional pneumatic cylinder connected to the main pneumatic cylinder and with a discharge pipe.

In addition, the additional pneumatic cylinder is equipped with a regulating device, made, for example, in the form of a spring-loaded surface and a stop screw.

FIG. 1 shows the described device with a pneumatic actuator in the initial position; in fig. 2 - the same, in the intermediate stage of the cycle.

The device comprises an actuator I with a tool 2 and an orienting guide 3 held in a movable state on the carrier part 4; rotation drive 5; drive translational movement, made in the form of a pneumatic cylinder 6 with a piston 7 and a return spring 8; a rocker arm 9 connecting the pneumatic actuator to the working member; an inertial element in the form of an additional pneumatic cylinder 10 connected by a pipe 11 with a pneumatic cylinder 6.

After turning on the rotational drive, loading into the guide 3 parts 12 and installing into the work zone of the part 13, the operator using the pedal (not shown) shows the command for the implementation of the working cycle. At the same time, air under pressure from the pneumatic network is supplied through the supply pipe 14 to the pneumatic cylinder 6, as a result of which the piston 7, overcoming the resistance of the spring 8, moves downward, re-moving the operating element 1 with the tool 2 and the carrier part 4 in the same direction. in restrictive

the element 15 of the carrier part 4 stops, and the working body 1 with the tool 2 continues to descend

When the tool 2 enters the cavity of the guide 3, the part 12 is held by means of spring-loaded grippers 16 and is pushed into the zone of its direct mating with the hole of part 13 (Fig. 2). At this point, the working body 1 slows down its movement or stops for a while (the delay time). In this case, under the action of a rotating tool 2 or from an individual drive, the guide 3 performs a rotational movement, as a result of which the part 12 is oriented relative to the aperture of the part 13 and they are preliminarily (before the tool begins to act) are aligned.

Slowing or stopping the movement of the working body 1 with the tool 2 occurs to the flow that the gap 7 of the pneumatic cylinder 6 crosses the area of the pipeline 11, which leads to the discharge of air into the additional pneumatic cylinder. To adjust the duration of the slow movement of the working body, the additional pneumatic cylinder is provided with a spring-loaded piston 17 and a stop screw 18.
