Description

The invention relates to process equipment for the manufacture of electric coils and can be used in radio engineering and electrical engineering.

The purpose of the invention is to improve the quality of winding by stabilizing the compression force of the core rollers.

Figure 1 shows the layout of the device; figure 2 - section aa in figure 1,

The device contains rollers 1 mounted on gear-shafts x 2, which can rotate on bearings 3 installed in levers 4 swinging on axles 5. The latter are fixed on housing 6o. On the recess of plate 7, the gear ring 8 can be rotated and the The gear shaft 9, which in turn, engages with the rack 10 of the power pneumatic end 11, which drives the rotation of the gear ring 8, the pneumatic cylinder is connected to the compressed air line via a distributor and a pressure reducing valve. Gears 12 are mounted on levers 4, which engage with a ring gear 8. Shaft gears 2 are engaged with seat wheels on axles 5 parasitic gear wheels (block gears) 13, which, in turn, j input t in engagement with the common central sz the wheel 14, associated with the drive of the winding machine. The gear unit consists of 15 central, upper 16 and lower 17 gears, which are spring-loaded; relative to the central gear 15 by means of torsion springs 18.

The device works as follows.

Before installing the core between the rollers I, air is fed into the cavity of the power cylinder 11, the rod-rod makes a translational motion and drives the gear shaft 9, which transmits rotation to the gear ring 8. The latter acts on the gears 12 mounted on the levers

4. As a result of this, all the levers 4 synchronously turn on the axis x 5, the rollers disengage. Gear shafts 2, moving along arcs centered on axles

the cylinder cavity P. Rod 10, moving progressively in the opposite direction and acting through the gear shaft 9, the gear ring 8 and gear 12, simultaneously reduces all the levers 4, the self-centering core with an accuracy determined by the accuracy of the holes in the body 6 along the axis 5 relative to its center, with the result that the core is clamped by the rollers 1.

In the case of winding two or more layers of wire on the core, the levers 4 are dispersed, rotating around the axles 5, and act on the rod 10 of the cylinder 11 through gears 12, toothed rim 8 and gear shaft 9, while the rod 10 moves progressively. Due to the presence of the pressure reducing valve, the pressure in the cylinder cavity does not change, so the force on the rollers 1 also does not change. The rotation of the central gear 14 through the parasitic gear wheel 13 is transmitted to the gear shafts m 2, on which the rollers 1 are placed. The design of the gear gear 13 ensures its backlash-free engagement with the gear shafts 2 and with the central gear wheel, which increases the winding accuracy { especially with sectional hank).
