Abstract

The invention relates to a lifting and transport engineering. The purpose of the invention is to increase the reliability of the device by eliminating torsional deformations of elastic rods. Active 1 and reactive 2 mass (M) devices are interconnected by an elastic suspension from resilient rods (C) which are radially arranged in pairs and connected by clamps 5. Each C 5 is attached at one end to active M 1, and the other to reactive M 2 Between M 1 and 2 there is an additional elastic connection in the form of inclined plates 3, set at an angle to the vertical, equal to the angle of inclination of the plane C 5 to the horizon. The device has a vibration exciter. When the device operates, the oscillation frequency M 1 relative to M 2 is equal to the frequency of the current pulsation. The stiffness setting C 5 is made until the natural frequency of the device coincides with the ripple frequency of the current. A change in the working length C 5 does not affect the magnitude of the angle a and the oscillation M 1 relative to M 2, since the angle is determined by the inclination of the plates 3. Since the axes C 5 are located in a plane inclined to the horizontal at an angle a, torsional deformations C 5 are excluded. . (L

The invention relates to a hoisting and transport machinery, in particular to vibratory charging devices, and can be used in various fields of machinery for automatic loading of piece blanks and parts into automatic process machines.

The purpose of the invention is to increase the reliability of the device by eliminating torsional deformations of elastic rods.

FIG. 1 shows the vibratory loading device, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The vibratory loading device includes active 1 and reactive 2 masses, interconnected by guides made in the form of inclined plates 3 of low rigidity, which provide a helical trajectory of movement of masses 1 and 2 relative to each other. On the active mass 1, a loading cup (not shown) is fixed, and the reactive mass is mounted on a fixed bed or stand by means of shock absorbers 4.

Radial elastic (round or square cross-section) rods 5 are installed in pairs and by means of the clamps b can be fixed on the active 1 and reactive 2 masses. The free ends of the elastic rods 5 are clamped by clamps, made in the form of strips 7 and 8, mounted with a bolt 9. The axes of the rods 5 are located in a plane inclined at an angle to a of the horizontal plane. Inclined plates 3 are set at the same angle a to the vertical. The inclination angle a is equal to the angle of oscillation of the active mass relative to the reactive

On the active mass 1 is fixed the bark 10, and on the reactive mass 2 - the core 11 with the electromagnet winding - the exciter.

On the active mass 1, the measles 10 is fixed, and on the reactive mass 2 - the core 11 with the winding of the electromagnet-excitation of oscillations.

Vibrating device works as follows.

When an electromagnet 11 is included in the AC network, it excites the active mass 1 relative to the reactive mass 2 with a frequency equal to the ripple frequency of the current.

The stiffness of the elastic rods 5, carried out by shifting the strips 7 and 8 in the radial direction, is adjusted as long as the natural frequency of the loading device as a whole, i.e. including the bowl, coincides (or exceeds by 2-3%) with ripple current frequency.

The change in the working length L of the elastic rods 5 does not affect the magnitude of the angle A of the oscillations of the active mass 1 relative to the reactive mass 2, since this angle is determined by the inclination of the plates 3, the rigidity of which for transverse bending is chosen to be the least acceptable for longitudinal bending.

Since the axes of the rods 5 are located in a plane inclined to the horizontal at an angle a, torsional deformations of the rods 5 are excluded. This positively affects the reliability and clarity of pinching them in the clamps and clamps. This increases the reliability of the device as a whole.
