Description

The present invention relates to machine tools for insulating rods of electric machine windings using a self-propelled carriage with an eccentric winding that moves along a guide strip.

The proposed machine differs from the known ones in that the guide strip for moving the self-propelled carriage has flexible inserts which allow changing the configuration of the guide according to the size and shape of the insulated section. Two smooth drive rollers are applied to move the wrapper, frictionally coupled with the guide strip. The tape carrier is discharged in the form of a finger, on which a roll of insulating tape is freely pulled, pressed in the radial direction by a spring-loaded lever.

This embodiment of the machine simplifies its design and speeds up changeover when isolating various types of windings.

FIG. 1 shows schematically a machine for insulating rods; in fig. 2 insulating head.

The application of tape insulation on the machine is achieved: by rotating around an insulated rod a hook with tapes located in the insulating head 7, and a translational movement of the insulating head along the guides m 2 (Fig. 1) The insulated section is fixed on racks equipped with universal holders 3 The adjustment of the machine in accordance with the size and shape of the section is carried out by a handle 4 on the slit, applied on the front edge of the frame, and also by moving the racks (with holders 3} associated with the moving parts of the guides 2 and arcs scales, applied to figured plates 5 and 6. Thus.

No. 143881-2 in the process of setting up the machine, the movable direction of the junction is set to: FS) in a new position, corresponding to the shape of the insulated section.

In the insulating head comprising a shuttle body, friction rollers and a drive with a variator, the movement is transmitted from the electric drive 7, through the upper shaft 8 of the variator, the overrunning clutch and the gear train .9 to Box W with the tape.

At the same time, the movement is transmitted through the lower shaft of the variator and the worm gear 12 to the friction rollers 13, which, in contact with the prismatic guides, allow the insulating head to move. The adjustment of the tape overlay is made by turning the dial 14, screwed onto the shaft 15, the second end of which is fastened to the levers carrying the variator discs. The axial movement of this shaft, bringing together one pair of disks, OHT, moves the second one apart at a time. In this way, the ratio of the revolutions of the shuttle and the friction rollers is adjusted to deactivate the latter and move the insulating head to serve knob 16, withdrawing the pin 17 from engagement with the worm wheel. The described machine has a stepless adjustment of the step of imposing a belt, carried out by a variator, which is combined with the drive and acts simultaneously on the speed of rotation of the shuttle and the friction rollers.
