Abstract

Usage: in the tire industry when assembling tires on an expandable multi-seat assembly drum. SUMMARY OF THE INVENTION: the device is provided with a mechanism for preliminary orientation of the side rings. The latter is made in the form of fixed beams fixed on racks. Two-arm levers are articulated on the beams. One end of the levers is associated with a drive. At the other ends of the arms are shoulders for the side ring. Radial grooves are made on the grips. The grooves are located across the V-shaped grooves. 6 ill.

Description

The invention relates to equipment for assembling tires of pneumatic tires and may find application in the tire industry, in particular when assembling tires on. expandable multi-seat assembly drum.

A device for landing on-board rings is known, comprising a movable carriage mounted on the rails and mounted on the rails by means of vertical struts for the side rings, a drive for reciprocating movement of the carriage along the assembly drum and a drive for moving the grippers to the assembly drum.

A disadvantage of the known device is that before fixing the grippers, it is necessary to use any additional means for refueling the side rings into the grippers, and the known mechanisms do not provide accurate orientation of the side rings relative to the grips

Another device is known for landing side rings on an assembly drum, comprising an axially movable carriage mounted on guides, vertical struts mounted on it and grippers for side rings with V-grooves radially movable from the drives, mounted on radially movable rods mounted between vertical racks .

The disadvantage of this device is that its design does not provide preliminary orientation of the bead rings with respect to the grips and their reliable final fixation in the perpendicular axis of the assembly drum of the plane — a significant take-off of the connecting plates is required, which therefore requires a significant movement of the plates in the radial direction from which the overall dimensions of the device increase and the working conditions of the collector are complicated

ABOUT

Ј 00

The aim of the invention is to increase the reliability of the device in operation and the accuracy of the fit of the bead rings.

This goal is achieved by the fact that the device is equipped with a mechanism for preliminary orientation of the side rings, made in the form of fixed beams fixed to the uprights and two-arm levers pivotally mounted on them, one ends of which are connected to the drive, and at the second ends there are shoulders for the side ring, moreover radial grooves are made on the grips located across the V-shaped grooves.

Figure 1 shows a General view of the device, a longitudinal section; figure 2 - combined sections aa and bb in figure 1; 3-6 - fixing of the side rings.

A device for landing side rings on an assembly drum comprises a movable carriage 2 mounted on rails 1 with struts 3 fixed thereon and radially movable grippers 4 for side rings 5. Between the racks 3, radially movable rods 6 are mounted, which are connected to the rods of the power cylinders 7. The grippers 4 are mounted on the rods 6 by means of cups 8 and are spring-loaded relative to the stacks 8 by a spring 9. The grippers 4 are made in the form of segments and provided on their arcuate surface with V-shaped grooves 10 and radial grooves 1 1, are made across the V-shaped grooves 10.

Fixed poles 12 are fixed on the posts 3, on which the two-arm levers 13 are pivotally fixed, one end of which is connected via the link 14 to the drive 15, and the other end is located in the radial groove 11 of the grip 4 and provided with a shoulder 16 for the side ring.

The device operates as follows.

In the initial position, the device is retracted from the assembly drum, the rod 6 (Fig. 1) with grippers 4 by means of cylinders 7 is radially allocated to the beams 12, the two-arm levers 13 are deflected by means of a rod 14 and an actuator 15.

For refueling into the device of the side rings 5, the two-arm levers 13 are mounted parallel to the grippers 4 (Fig. 3) and the side arms 16 are mounted on the shoulders 16

ring 5, thereby clearly guiding it relative to the grips 4.

Then the actuators 7 are turned on, by means of rods 6, the grippers 4 (Fig. 4) are led to the side ring 5, which enters the V-shaped groove 10 of the gripper 4 - the side ring is surrounded by the grippers 4 along the outer perimeter. In this case, the end of the lever 13 enters the radial groove 11 of the grip 4, securely fixing the bead ring 5 in the V-shaped

notch 10.

After that, the drive 15 (Fig. 1) is turned on and by means of the link 14 the two-arm levers 13 (Fig. 5) are retracted from the side rings. 5.

The carriage 2 is moved to the assembly drum and the rings 5 are planted on this drum. After the rings 5 are fixed in the grooves of the drum, the actuators 7 retract the rods 6 with the grippers 4 from the drum (Fig. 6).

Then the cycle of work is repeated.
