Description

The invention of OTFiocHTCH to electrical engineering, namely, devices for putting on shielding braid on H1-ut wires and.

The invention has advanced the technological capabilities.

FIG. 1 shows a device for putting on shielding, its braids on the wiring harness and cables, general view; in fig. 2 --- braiding mechanism along the wiring harness and cables; in fig. 3 - kinematic scheme of drive for traction rollers; in fig. 4 - the same, left view; in fig. 5 principle electrical circuit for cyclic drive control of traction rollers; in fig. 6 and 7 are sequential diagrams of the operation of the mechanism of stretching of the braid along the wiring harness and cables.

The device for putting on a screening braid on the cable harness and cables contains a braid feeding mechanism arranged in the housing 1, made in the form of i ruins of friction rollers 2, interchangeable mandrel (needle) 3 and drum 4, kinematically connected with a cli - at the time of the transfer 5 with a drive motor 6, and the sender 7 braids 8.

At the exit of the interchangeable mandrel, yinKo 9 is located, to which the end of the wiring harness 10 is fixed, wound up in the block of the braiding mechanism. The spacing mechanism contains six blocks 11 mounted on a rack 12 mounted on a bed 13. The splicing mechanism consists of two traction rollers 14 and 15, turning oppositely in opposite directions. The driven traction roller 14 through the timing gear 6 and the tension rollers 18 and 19 moving in the grooves 17 are spring loaded 20 connected to the driving traction roller 15, kinematically connected to the drive motor 21. The traction roller 14 is mounted in a rack 12 with the possibility of radial slip along the groove 22 along the axis of the centers of the traction rollers 14 and 15 and spring-loaded relative to the post 12 by the spring 23. On the traction rollers 15 of all the mechanisms of the stretching mechanisms there is a harness n) of the gadfly C) attached to the replaceable mandrel 3 lash feeders APIS.

The cycle control scheme of the electric motor of the pulling mechanism consists of an adjustable time interval setting 24, which, at certain and equal intervals, contacts 25 turns on either the relay 26 for switching on drives of electric motors 27, or the relay 28 for switching on drives for electric motors 29, or

relays 26 and 28 to simultaneously turn on all the motors in the device boot mode.

The device works as follows.

A cable 10 is spirally wound onto the traction rollers 15 of all six mechanisms of the pulling, one end of which is fixed on the ear of the interchangeable mandrel 3, and the other freely placed between the traction rollers 14 and 15. The braiding 8 is alternately turned on by two groups of electric motors located radially at an angle of 120 °. When electric motors 29 of the same group are turned on, sections of the wiring harness with a shielding braid turn out to be temporarily fixed relative to the pillar 12, and pairs of traction rollers belonging to the other group pull the shielding braid over the wiring harness.

When another group of electric motors 27 is turned on, the braid slides over the wiring harnesses in adjacent areas.

Such an embodiment of the device makes it possible to put the shielding braid on the wiring harnesses and cables of different diameters and stiffnesses, which significantly expands the process capabilities, as well as reduces the time for readjustment when switching from one size to another.
