SPRINGS in DRUM SH-1NY in the drum housing. The base I of the device is made with a protrusion 2, having cylindrical fluff 3, in which: the collet 4 freely enters and the washer 5 closes the slot 6 of the collet from the western spring 7 iium of its lining 8 (Fig. 3) in them during winding. The shaft 9 of the spring motor is closed in the hole 10 of the collet under the action of a cylindrical spring II stretching which abuts one end of the collet 12 of the collet and the other at the bottom of the bore of the sleeve 13 freely rotating from the electric motor 14 through a flexible link 15 at the base of the axial displacement axial displacements . The sleeve 13 sends a toothed vein 16, through which rotation is transmitted through an intermediate wheel 17 to gear 18, rigidly mounted on axis 19 on the lower side of the base, Ila to the other end of the axis a gear collar 20 is rigidly fixed, having a groove 21 in the middle part, with which A strap 22 is attached, attached to the top of the base with pin 23. In the left part of plate 22 (FIG. I), a protrusion 24 is made, which enters the groove 21 and has a bevel 25 to grip the lining 8 pressed by the gear wheel 20 to the spring 7. Right part of the strap 22 fits tightly against mentioned 2 so that its side plane 26 coincides with the plane 27 on the protrusion 2 formed by the window 28 in the protrusion; Window 28 serves for the passage of the winding bar 7 to the boring 3 of the protrusion while winding it onto the drum shaft 9. During winding the spring 7 moves into The boring 3 along the groove 29 is formed by the plane 26 of the bar 22 and the side plane 30 of the movable lever 31, which is reinforced by a hinge butt axle 32 on the base. Lever 31, when the clock spring is installed on the drum shaft, is pulled to the side by the handle 33, and when curling it approaches the wind spring bar 22. Projection 34 prevents popping the spring upwards for tightly mating the inner thread of the winding spring makes a slightly smaller diameter of the shaft of the drum shaft 35 and the clamp 36 moving in the vertical direction to fit the inner shaft onto the shaft. Punch 35 has a hole with a $ 7 second support the baraan shaft during winding5 and the chamfer 38, which provides for the internal turn of the air spring to the mounting dimension of the drum shaft. The clamp 36, moving relative to the punch 35, blasts the spring 39 onto the shaft up to the ax 5 and rests on the groove 40 of the protrusion 2, preventing the spring from escaping from the top. The spring 41 returns the punch 5 to its original position after lifting the burned bit 36, The lever 42 turns for transferring the winding wound spring 3 into the body of the drum 43, (FIG. 4) after lifting the burned piece with the punch. The device works in the following way. By pressing the snub 42, the collet 4 moves upwards and the hole 10 is inserted into the lower pin of the drum shaft 9; when releasing the lever 42, the collet with the shaft lowers until it stops against the sleeve 13. With the retracted lever 31 of the plant, the spring 7 is folded with an internal coil on the end of the fitting diameter of the drum shaft (position a in FIG. 1). 38 separates the inner coil, and the end of the 39 PZ clamp will send the spring down to the stop in washer 5; while the inner turn tightly encloses the bore diameter of the drum shaft (position b in fig. 1). The free part of the winding spring (fig 2) is inserted into the window 28 and placed on the base between the bar 22 and the lever 31, which approaches the bar 29 for directional movement of the winding spring when winding. When the electric motor Eel 14 is turned on through the flexible coupling 15, the collet 4 rotates with the drum shaft and the winding spring 5 which is wound on the drum shaft by engaging the hook on the window with the window on the horn (friction of the spring coil. I and the gear wheel 20 rotates as the collet rotates which, when the lining approaches, presses it against the spring and to the plane 30 of the lever 31. The lining is pressed against the teeth of the wheel 20 rotating at such a speed that its speed at the points of contact with the knob 7 is in cijopoH y movement of the spring and more than the linear speed of the spring of the lining itself. This is achieved by installing an appropriate gear ratio between the gear ring 16 of the sleeve 13 and gear 18, thus ensuring that the lining 8 is tight against the spring 7, which is maintained as it moves along the notch 29 the entrance to the bore 3 of the protrusion 2. At this, the winding process ends, GF 36 with a punch 35 is retracted upwards, to the groove 40 of the protrusion

2, a drum case 43 (FIG. 4) is superimposed, into which, pressing the lever 42 and lifting the collet 4, the factory winds up the spring with the shaft of the drum.

Inventive

The device for winding and inserting the winding spring into the drum containing the spring winding mechanism on the shaft and transferring it into the drum body, is characterized in that, in order to improve performance and avoid damage to the lining, the winding mechanism is equipped with a rotated gear for pressing the lining to the spring and a groove spring guide with pad.
