Недостатком известного устройства является то, что сначала осуществляют сборку одного из углов угольника и только после этого обеспечивают окончатель. ную сборку угольника.A disadvantage of the known device is that they first assemble one of the corners of the square and only after that provide the final. new assembly of the square.

Цепь изобретения - повышение производительности за счет одновременной сбор-^‘ ки всех элементов изделия и механизации процесса сборки.The chain of invention is an increase in productivity due to the simultaneous assembly of all the elements of the product and the mechanization of the assembly process.

Поставленная цель достигается тем, что прижимные элементы выполнены в виде вилок V -образной формы и установлены с возможностью перемещения в плос- ’ кости собираемого изделия, причем углы между зубцами вилок равны соответствующим углам собираемого изделия. ·This goal is achieved in that the clamping elements are made in the form of forks of a V-shape and are mounted with the possibility of movement in the plane of the bone of the assembled product, and the angles between the teeth of the forks are equal to the corresponding angles of the assembled product. ·

На чертеже изображена конструктивная схема устройства в положении 'перед сборкой',The drawing shows a structural diagram of the device in the position 'before assembly',

В одной плоскости расположены жесткий неподвижный прижимной элемент*-, упор 1, выполненный в виде двухгранного угла, величина которого равна одному из углов собираемого угольника. В этой же плоскости размещены два подвижных прижимных элемента-упора 2 и 3. Каждый из них выполнен V-образным, Состоящим из двух зубцов 4 и 5, и имеет возможность перемещаться своим хвостиком 6 в направляющих 7, причем последние ориентированы параллельно стороне угольника, прилегающей к гране двугранного угла упора 1. Один зубец 4 параллелен направляющей 7, а другой зубец 5 расположен относительно первого под углом, равным углу угольника как по величине, так и по направлению. Хвостовик 6 жестко, соединен с сердечником электромагнита 8. Точно так выполнен и второй из подвижных упоров 3. Оба электромагнита включены в электросеть параллельно и управляются общим пускателем, что обеспечивает одновременность их действия.In one plane there is a rigid fixed clamping element * -, an emphasis 1, made in the form of a dihedral angle, the value of which is equal to one of the angles of the assembled square. In the same plane there are two movable clamping elements-stops 2 and 3. Each of them is made V-shaped, consisting of two teeth 4 and 5, and has the ability to move its tail 6 in the guides 7, the latter oriented parallel to the side of the square adjacent to the face of the dihedral stop angle 1. One tooth 4 is parallel to the guide 7, and the other tooth 5 is located relative to the first at an angle equal to the angle of the square both in magnitude and direction. The shank 6 is rigidly connected to the core of the electromagnet 8. The second of the movable stops 3 is made in exactly the same way. Both electromagnets are connected in parallel to the mains and are controlled by a common starter, which ensures their simultaneous action.

Устройство работает следующим образом.The device operates as follows.

На плоский стол 9 укладывают планки 10, из которых в данной операции собирают угольник таким образом, чтобы концы последних разместились в дву гранном углу упора 1 и между зубцами 4 и 5 упоров 2 и 3. После этого включают общий пускатель, в результате чего упоры 2 и 3 перемещаются вдоль направляющих 7 в направлении упора 1 до соприкосновения и сжатия планок 10. Если стыки последних смазаны, например, клеем, сборка угольника при этом оканчивается. Электромагниты 8 отключаются, и подвижные упоры 2 и 3 возвращаются в исходное положение.Planks 10 are laid on a flat table 9, from which, in this operation, a square is assembled so that the ends of the latter are placed in the dihedral angle of the stop 1 and between the teeth 4 and 5 of the stops 2 and 3. After that, the common starter is turned on, as a result of which the stops 2 and 3 move along the guides 7 in the direction of the stop 1 until the strips 10 touch and compress. If the joints of the latter are lubricated, for example, with glue, the assembly of the square ends. The electromagnets 8 are turned off, and the movable stops 2 and 3 are returned to their original position.

Технико-экономические преимущества изобретения заключаются в том, что отпадает необходимость дальнейших операций по подгонке углов угольника, а так же в повышении производительности. Имеются большие возможности к автоматизации процесса.Technical appraisal and economic advantages of the invention consist in the fact that there is no need for further operations to adjust the angles of the square, as well as to increase productivity. There are great opportunities for process automation.
