(54) DEVICE FOR INSTALLATION FLAT

SPRING RINGS IN EXTERNAL SEASONS

CYLINDRICAL DETAILS

one

The invention relates to mechanical engineering and can be used in the assembly industry for mounting flat spring rings on shaft-like parts using automatic equipment, including manipulators.

A device for mounting flat spring rings in the outer grooves of cylindrical parts is known, comprising a mounting head, a pusher, drives for displacing the mounting head and a pusher, a magazine, as well as a sliding ring feed mechanism and an unclamping mechanism 1.

The disadvantages of the known device are the impossibility of successively mounting several rings on one part into grooves distant from the end of the part, as well as the difficulty of using the device having several actuators with individual drives as an assembly tool in automatic manipulators.

The purpose of the invention is to expand the technological possibilities of assembling rings with the help of automatic manipulators.

This goal is achieved by the fact that the mounting head is provided with a nozzle.

in which sockets and stops are made, the feed mechanism of the rings is made in the form of a pinion gear mechanism installed with the possibility of interaction with the pusher of the mounting head, and the mechanism for opening the rings is designed in the form of a spring-loaded guide bar and a wedge mounted on the feed mechanism.

In addition, the shop is mounted rings made in the form of two adjustable rails, equipped with ribs, and two adjustable racks mounted on the feeder.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one.

The device for mounting the rings (FIG. 1) contains a mounting head, mechanisms J5 for feeding and unclamping the rings and a magazine.

Claims (2)

The mounting head consists of a housing 1 (Fig. 1) with a shank 2 serving to install it in an automatic manipulator or in other assembly equipment (not shown in the drawing). In the housing 1 20 there is a pusher 3 with a screw 4. At the bottom of the housing 1 of the mounting head, a nozzle 5 is mounted with two sockets 6 and two stops 7 (Fig. 2). The feed mechanism of the mounted ring consists of the housing 8, in which the rack-pinion gear mechanism 9 of the gate 10 is installed, which interacts with the pusher 3. On the feed mechanism there is a magazine of mounted rings 11, a spring-loaded guide bar 12 and a ring wedge mechanism 13 The magazine is formed by two adjustable strips 14 with base ribs 15 and two adjustable stands 16, with the slats 14 and stands 16 fixed to the top plate 17 of the feed mechanism. Setting the rings works as follows. The mounting head moves the manipulator to the feed mechanism, after which the pusher 3, interacting through the screw 4 with the drive, lowers and actuates the rack and pinion mechanism 9. In this case, the spindle 10 moves towards the mounting head (Fig. 2) and pushes out foot bottom mounted ring 11, which is taken out of engagement with the base ribs 15 of the magazine bars 14 and is oriented by the spring-loaded bar 12. With further movement by the hook 10, the ring 11 is guided by the bar 12 and falls with its notch on the wedge 13, through tion which razzhimaets. The presence of the stops 7 on the nozzle 5 prevents the ring 11 from jumping upwards during unclamping. At the end of the stroke of the spigot 10, the ring 11 with its protrusions is pushed into the sockets 6 of the nozzle 5 and takes the position shown by the dotted line in FIG. 2. In this position of the ring 11, the spring-loaded strip 12 is pressed downward by it. After that, the pusher 3 and the spider 10 are retracted to their initial positions, and the mounting head rises and, together with the expanded ring 11, is moved to the shaft mounted in the tool (not shown in the figure). The mounting head is lowered, putting the ring on the shaft, until the ring is aligned with the groove. The bends of the mounted ring are prevented by the stops 7. Then the mounting head moves away from the shaft in the transverse direction, allowing the ring protrusions to come out of the sockets 6, the ring is compressed and takes its place in the shaft groove. The economic effect of implementing the invention is achieved both by expanding the technological capabilities of the device when mounting the spring thrust flat rings on shafts of various configurations, and by using automatic manipulators for assembly.
