Description

Изобретение относится к машиностроению И может быть использовано в вибрационных загрузочных устройствах металлорежущих станков и автоматических линий.The invention relates to mechanical engineering And can be used in vibration loading devices of metal-cutting machines and automatic lines.

Известен вибрационный питатель, содержащий привод, чашу с винтовым лотком и спиральньгм коническим дном, образованным вращением' прямой линии вокруг оси чаши так, что верхний ближний конец ее к указанной оси остается неподвижным, а нижний дальний перемещается по винтовой линии лотка [1]. *Known vibration feeder containing a drive, a bowl with a helical chute and a spiral conical bottom formed by rotation of a straight line around the axis of the bowl so that its upper proximal end to the specified axis remains stationary, and the lower distal moves along the helix of the chute [1]. *

Недостатком устройства является недостаточно высокая производительность из-за смены угла наклона образующей спирального коничес- , кого дна к горизонтальной плоскости, замедляющей захват деталей винтовым лотком чаши.The disadvantage of this device is not high enough productivity due to a change in the angle of inclination of the generatrix of the spiral conical, whose bottom is to the horizontal plane, slowing down the capture of parts by the screw tray of the bowl.

Известен и другой питатель, содержащий вибробункер с винтовым лотком и дном, выполненным в виде винтовой конической поверхности с шагом, равным шагу винтового лотка [2].Another feeder is known, comprising a vibratory hopper with a screw tray and a bottom made in the form of a helical conical surface with a step equal to the pitch of the screw tray [2].

Данный питатель не лишен указанных выше недостатков.This feeder is not without the above disadvantages.

Целью изобретения является повышение производительности устройства за счет увеличения зоны захвата деталей винтовым лотком.The aim of the invention is to increase the productivity of the device by increasing the capture zone of parts with a screw tray.

Указанная цель достигается тем, что дно чаши выполнено в виде косого геликоида, образующая винтовой поверхности которого пересекает ось чаши под углом, соответствующим углу пересечения оси чаши прямой линией, лежащей в плоскости, касательной к верхней поверхности винтового лотка. ,This goal is achieved by the fact that the bottom of the bowl is made in the form of an oblique helicoid, the helical surface of which intersects the axis of the bowl at an angle corresponding to the angle of intersection of the axis of the bowl with a straight line lying in a plane tangent to the upper surface of the screw tray. ,

На фиг. 1 показано устройство, общий вид; на фиг. 2 - дно, разрез.In FIG. 1 shows a device, a General view; in FIG. 2 - bottom, section.

Вибрационный питатель состоит из основания 1, электродвигателя 2, вибратора 3, амортизаторов 4, дебалансов 5, чаши 6 с винтовым лотком 7 и дном 8 отводящего лотка 9. Дно питателя содержит конус 10, бобышку 11, стенку 12 и кольцо 13.The vibrating feeder consists of a base 1, an electric motor 2, a vibrator 3, shock absorbers 4, unbalances 5, a bowl 6 with a screw tray 7 and a bottom 8 of the discharge tray 9. The bottom of the feeder contains a cone 10, a boss 11, a wall 12 and a ring 13.

Устройство работает следующим образом.The device operates as follows.

При включении электродвигателя 2 вибраторы 3 с дебалансами 5 обеспечивают эллиптические колебания точкам питателя, под действием которых детали движутся по дну 8 ча- 'When the motor 2 is turned on, vibrators 3 with unbalances 5 provide elliptical vibrations to the points of the feeder, under the action of which the parts move along the bottom for 8 hours

ши 6 к винтовому лотку 7 и далее по нему _;вплоть до выхода через лоток 9.shi 6 to the screw tray 7 and further along it _; until you exit through tray 9.

Благодаря постоянному наклону образующей дна к оси чаши обеспечивается равномерность движения детален от центра чаши к ее наружной поверхности на всем протяжении сопряженного участка дна 8 и винтового лотка 7.Due to the constant inclination of the bottom generatrix to the axis of the bowl, uniformity of movement is ensured in detail from the center of the bowl to its outer surface throughout the entire conjugate section of the bottom 8 and the screw tray 7.

Claims

The invention relates to mechanical engineering and can be used in vibratory loading devices of machine tools and automatic lines. A vibratory feeder is known, which contains a drive, a thicket with a screw tray and a spiral conical bottom formed by rotating a straight line twisting the axis of the tip so that its upper proximal end to the specified axis remains stationary, and the lower long distance moves along the helix of tray 1. The drawback of the device is not high enough performance due to the change of the angle of inclination of the forming spiral conical bottom to the horizontal plane slowing down the capture of parts by the screw tray of the thicket. Another feeder is known, containing vibrobunker screw trough and bottom vypo nennym a screw with a conical surface schagom equal schagu screw feeder tray 2. This is not without drawbacks mentioned Your. The aim of the invention is to increase the productivity of the device by increasing the area of engagement of parts with a screw tray. This goal is achieved by the fact that the bottom of the thicket is made in the form of an oblique helicoid, which forms a helical surface that intersects the axis of the thickening at an angle corresponding to the angle of intersection of the axis of the thickening straight line lying in the plane tangential to the upper surface of the screw tray. , FIG. 1 shows the device, a general view; in fig. 2 - bottom, cut. The vibrating feeder consists of the base 1, the electric motor 2, the vibrator 3, shock absorbers 4, unbalances 5, tea 6 with screw tray 7 and bottom 8 of the discharge tray 9. The bottom of the feeder contains a cone 10, a bob 11, a wall 12 and a ring 13. The device works in the following way. When electric motor 2 is turned on, vibrators 3 with unbalances 5 provide elliptical oscillations to the points of the feeder, under the action of which the parts move along the bottom of the 8th b to the screw tray 7 and further along it up to the exit through the stream 9. Due to the constant inclination of the bottom forming to the bowl axis uniformity of movement of parts from the center of the bowl to its outer surface throughout the conjugate section of the bottom 8 and the screw tray 7. Formula of the invention Vibration feeder comprising a base, shock absorbers, a vibrator and a bowl a bottom and a screw tray on its side surface, characterized in that, in order to increase productivity, the bottom of the feeder bowl is designed as an oblique helicoid, forming i the screw surface of which crosses the axis of the bowl at an angle corresponding to the angle of intersection of the axis of the bowl with a straight line, lying in a plane tangent to the upper surface of the screw tray.
