(54) УСТРОЙСТВО ДЛЯ СБОРКИ ПОД СВАРКУ(54) DEVICE FOR ASSEMBLY UNDER WELDING

1one

Изобретение относитс к сварке, а именно к устройствам дл сборки под сварку изделий, имеющих замкнутый контур.The invention relates to welding, in particular, to devices for assembling, for welding, products having a closed loop.

Известно устройство, содержащее плиту , в отверстии которой смонтирован стержень с руко ткой, подпружиненный прижимом , установленным с возможностью перемещени вдоль стержн , и торцовым эксцентриком 1.A device is known comprising a plate, in the hole of which a rod with a handle is mounted, spring-loaded with a clamp mounted for movement along the rod, and with an end eccentric 1.

Известное устройство сложно и имеет большой вес.The known device is difficult and has a lot of weight.

Известно также устройство дл - сборки под сварку, преимущественно изделий, имеющих замкнутый контур, содержащее базовый диск и кольцо с выполненными на их опорных поверхност х центрирующими выступами , а также прижимы, равномерно расположенные по окружности диска и кольца 2.It is also known a device for assembling for welding, mainly products having a closed loop, comprising a base disk and a ring with centering lugs on their supporting surfaces, as well as clamps uniformly spaced around the circumference of the disk and ring 2.

Известное устройство вл етс недостаточно производительным, так как крепление прижимов осуществл етс с помощью винтов.The known device is not sufficiently productive, since the fastening of the clamps is carried out with the help of screws.

Цель изобретени - повыщение производительности и надежности фиксации собираемых изделий.The purpose of the invention is to increase the productivity and reliability of fixing the assembled products.

Поставленна цель достигаетс тем, что в устройстве дл сборки под сварку, содержащем базовый диск и кольцо с выполненными на опорных поверхност х центрирующими выступами, а также прижимы, равномерно расположенные по окружности диска и кольца, диск и кольцо снабжены поворотными кулачками, а каждый прижим выполнен в виде пары поворотных рычагов с захватными лапками, установленных на одной оси, подпружиненных один относи10 тельно другого и снабженных ограничител ми их поворота, причем на каждом рычаге выполнено отверстие дл кулачков диска и кольца.The goal is achieved by the fact that in the device for assembly for welding, comprising a base disk and a ring with centering lugs on the supporting surfaces, as well as clamps uniformly spaced around the disk and ring, the disk and ring are provided with rotating cams, and each clamp is made in the form of a pair of pivoting levers with gripping legs mounted on the same axis, spring-loaded one relative to the other and provided with restraints on their rotation, with each hole having an opening for the cams disk and ring.

Профильна часть кулачка выполнена 15 в виде эллипса с соотнощением большой оси и диаметра отверстий 1:3.The profile part of the cam is made 15 in the form of an ellipse with the ratio of the major axis and the diameter of the holes 1: 3.

На фиг. 1 представлено устройство, общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - узел креплени кулачков; на фиг. 4-крепление рычагов.FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 — cam attachment unit; in fig. 4-mount levers.

Claims

The assembly for welding includes a disk 1 and a ring 2, on which centering cylindrical protrusions are made, evenly around the circumference of the disk 1 and the ring 2 are located cams 3, pins 4 and clamps, each of which is made in the form of a pair of pivoting levers 5 mounted on a common axis 6, fixed respectively on disk 1 and ring 2, and the levers 5 of each pair are spring-loaded with each other by a spring 7. On each lever 5, legs 8 and holes 9 are made. Through the holes 9 of each pair of levers 5, a cam 3, made in the shape of an ellipse, is passed, d The large axis of the axis refers to the diameter of the hole 9 on the lever 5 as 1: 3. Each lever 5 also has a radial groove in which the corresponding tongue 4 is installed, which is the limiter of the angle of rotation of the lever 5. The device operates as follows. On the base disk 1 with centering cylindrical protrusions install parts 10, the position of which is fixed by rotating about axis 6 with the help of cam 3 of each pair of levers 5, paws 8 of which press the protrusions onto the communicated parts x 10. Then set the ring 2 from above, to which The levers 5 mounted on it clamp the upper part of the parts 10. The clamping in the form of two rotary levers allows, when one cam is turned, to clamp the parts at four points at once, which increases assembly time, and the ratio of the length of the larger axis of the cam ellipse to the diameter of the hole 9 on the levers of each pair as 1: 3 allows the cam 3 to slip against the walls of the hole 9. Invention 1. The device for assembling for welding, mainly closed loop products, containing the base a disk and a ring with centering protrusions formed on their support surfaces, as well as clamps evenly spaced around the circumference of the disk and ring, characterized in that, in order to increase productivity and reliably fixing the assembled products, the disk and the ring are equipped with rotating cams, and each clamp is made in the form of a pair of pivoting levers with gripping legs mounted on the same axis, spring-loaded one relative to the other and provided with limiters of their rotation, and on each lever there is an opening for the cams of the disk and rings. 2. A device according to claim 1, characterized in that the profile part of the cam is made in the form of an ellipse with a ratio of the major axis and the diameter of the holes 1: 3.
