(54) УСТЮЙСТВО ДЛЯ СБОРКИ ДЕТАЛЕЙ(54) APPROACH TO PART ASSEMBLY

II

Изобретение относитс к специальному технологическому оборудованию сборочных производств и может найти применение в различных отрасл х машиностроени преимущественно дл сборки деталей типа валвтулка .The invention relates to special processing equipment of assembly plants and can be used in various fields of engineering mainly for the assembly of shaft-type parts.

Известно устройство дл сборки деталей, содержащее корпус, установленный в нем с возможностью перемещени захват, и электромагнит 11.A device for assembling parts, comprising a housing, a gripper mounted therein, and an electromagnet 11 are known.

Недостатками известного устройства вл ютс низка надежность и производительность сборки.The disadvantages of the known device are low reliability and performance of the assembly.

Цель изобретени - повыщение надежности и производительности.The purpose of the invention is to increase reliability and performance.

Цель достигаетс тем, что устройство снабжено приводом вращени рамкой и на- правл ющей, причем рамка расположена в корпусе и св зана с приводом вращени , а электромагнит и направл юща закреплень в рамке таким образом, что их оси параллельны между собой и перпендикул рны направлению сборки, при эгпм чахват размещенThe goal is achieved in that the device is provided with a rotational drive frame and a guide, the frame is located in the housing and connected to the rotational drive, and the electromagnet and the guide is fixed in the frame so that their axes are parallel to each other and perpendicular to the assembly direction when egpm chahvat placed

нгг направл ющей и подпружинен относительно злектромапшта.The ngg of the guide is spring-loaded relative to the electric socket.

На чертеже изображено предлагаемое устройство , общий вид.The drawing shows the proposed device, a General view.

Устройство дл сборки деталей содержит корпус 1, вл ющийс или составной частью сборочного автомата или рукой манипул тора (не показаны), в котором ш подшипниках 2 установлена с возможностью вращени рамка 3 с валом 4 и шкивом 5, причем щкив 5 с помощью ременной или иного вида передачи 6 соединен с приводом 7 вращени , например с электродвигателем.The device for assembling parts includes a housing 1, which is either an integral part of an assembly machine or a manipulator arm (not shown) in which the bearings 3 are rotatably mounted with the shaft 4 and the shaft 4 and the pulley 5, with the belt 5 or other The transmission type 6 is connected to a rotational drive 7, for example, an electric motor.

Claims

In frame 3, a guide 8 is fixed perpendicular to the axis of the assembly, on which bushing 9 with a rod 10 is mounted with the possibility of translational movement, on which is gripped a gripper 11 with one of the supports. The parts 12 are fitted. A spring 13 and an electromagnet 14 are installed between the frame 3 and the sleeve 9. Another piece 15 is assembled (a sleeve with a hole) is fed to the assembly site with a transport device 16 of any kind. 390 The device operates as follows. The transport device 16 delivers the item 15 to the place of assembly. The part 12 (shaft or screw) is fed into the grip 11. As soon as the parts 12 and 15 have their initial position, a sinusoidal voltage is applied to the actuator 7 and the electromagnet 14 by the signal of the respective sensors. The shaft 4 begins to rotate and with it rotates the frame 3, the grip 11 and the part 12, and the sleeve 9 is progressively displaced by its end playing the role of the core of the electromagnet 14, while the spring 13 is extended. When supplying, for example, reverse polarity to the electromagnet 14, the sleeve 9 extends from the electromagnet and the spring 13 is compressed. By selecting the rotational speed of the actuator 7 and the rate of increase in voltage on the electromagnet 14, the parameters of the search trajectory can be changed depending on the gap between the parts 12 and 15. In addition, the time taken for part 12 of the orientation zone to be changed. As part 12 traverses the search path, body 1 exerts an external force that presses this part to part 15. As soon as the search path falls into the assembly area, i.e. The part 12 enters the hole of the part 15, according to the signals of the vertical displacement sensors (not shown) of the jaw 11, the part 12 is released, and the voltage on the electromagnet 14 and the actuator 7 stops. The spring 13 returns the sleeve 9 to its original position. The build cycle is completed. If part 12 is a screw and part 15 has a thread in the hole, then when part 12 enters the hole, the signals from the vertical displacement sensors relieve the voltage from the electromagnet 14, however, the frame 3 and the grip 11 continue to rotate with detail 12 to full installation screw in place. An apparatus for assembling parts, comprising a Kopiyc, a gripper that is mounted therein, and an electromagnet, characterized in that, in order to increase reliability and performance, it is provided with a rotating drive, a frame and a guide, the frame located in the housing and driven with rotational drive, and the electromagnet and the guide are fixed in the frame so that their axes are parallel to each other and perpendicular to the assembly direction, while the grip is placed on the guide and is spring-loaded relative to electromagnet.
