(54) МНОГОПОЗИЦИОННЫЙ СВАРОЧНЫЙ МАНИПУЛЯТОР(54) MULTI-POSITIONAL WELDING MANIPULATOR

Изобретение отноште к устройствам дл сборки и сварки узлов с предварительным подогревом,- в частности узлов с кольцевыми швами.The invention relates to devices for assembling and welding units with preheating, in particular units with ring seams.

Известен манипул тор, содержащий планшайбу с поворотными шпиндел ми на каждой позиции и единый привод дл вращени шпинделей и дл смены позиций планшайбы 1.A manipulator is known, which contains a faceplate with rotary spindles at each position and a single drive for rotating the spindles and for changing the positions of faceplate 1.

Этот манипул тор не обеспечивает автоматической сварки деталей с предварительным подогревом, так как загрузке и сн тии деталей в позиции загрузки необходимо останавливать вращение всех шпинделей.This manipulator does not provide automatic welding of parts with preheating, since loading and removing parts at the loading position requires the rotation of all spindles to be stopped.

Наиболее близким по техническому решению вл етс многопозидионный сварочный манипул тор, содержащий поворотную планшайбу с закрепленными на ней шпиндел ми на каждой позиции, единый привод поворота планшайбы и вращени шпинделей , а также устройство дл отключени вращени шпиндел на позиции загрузки 2.The closest in technical solution is a multi-spec welding welding arm containing a rotary faceplate with spindles fixed on it at each position, a single drive for rotating the faceplate and rotating spindles, as well as a device for disabling the spindle rotation at the loading position 2.

В этом устройстве имеетс возможность отключени одной из позиций, но отключение производитс с помощью кулачковой муфты не автоматически, что снижает его производительность.This device has the ability to disable one of the positions, but the disconnection is performed using the cam clutch is not automatically, which reduces its performance.

Цель изобретени - повышение производительности путем обеспечени автоматического отключени шпиндел на позиции загрузки.The purpose of the invention is to increase productivity by ensuring automatic spindle shutdown at the loading position.

С этой целью на выходном валу привода по оси поворота планшайбы и на шпиндел х закреплены шкивы с охватывающими их ремн ми , а устройство дл отключени вращени шпиндел на позиции загрузки выполнено в виде закрепленного на основании по оси поворота планшайбы кулачка с вогнутой поверхностью со стороны позиции загрузки и шарнирно смонтированных на планшайбе соответственно каждой позиции подпружиненных двуплечих рычагов дл нат жени ремней, одно из плеч каждого из которых установлено с возможностью взаимодействи с кулачком, а другое - с соответствующим ему ремнем.To this end, pulleys with surrounding belts are fastened on the output shaft of the drive along the axis of rotation of the faceplate and on the spindles, and the device for deactivating rotation of the spindle at the loading position is made of a cam with a concave surface on the side of the loading position and pivotally mounted on the faceplate, respectively, of each position of the spring-loaded two-arm levers for tensioning the belts, one of the arms of each of which is mounted with the possibility of interaction with the cam, and the other - with the associated belt.

Claims

The manipulator contains a rotary plate 1 mounted on the base with spindles 2 located on it, as well as an actuator that consists of a gearmotor 3 and a variator 4. The output shaft of the drive is connected to the plate 1 by means of a conical pair 5, and with pulleys through a conical pair 6 7, transmitting the rotation by means of the belts 8 and the tongs 9 onto the spindles 2. On the base, along the axis of rotation of the faceplate 1, a cam 10 is installed, with a concave surface on the side of the loading position. On the face plate 1, each arm has two shoulders levers 11, each of which has a roller 12 fixed to one of its arms, and a supporting roller 13 on the other arm. The levers 11 are spring-loaded with springs 14 towards the cam 8. The manipulator works as follows. . The gearmotor 3 is turned on. At the loading position on the spindle 2, the workpiece of the unit 15 is secured. The gear 16 is disengaged. Faceplate 1 does not rotate. At the loading position, the lever 11, through the action of the spring 14, interacts through the support roller 13 with the concave surface of the cam 10 and retracts the tension roller 12 from the belt 8, which is loosened and the spindle 2 does not rotate at this position. After securing the blanks of unit 15, gear 16 is brought into engagement, faceplate 1 is rotated at a predetermined angle, gear 16 is taken out of engagement. The spindle 2 with the assembled node 15 occupies the position of heating, on which a ring gas burner (not shown) is installed. When turning the faceplate 1, the roller 13, interacting with the protrusion of the cam 10, rotates the beam 11 relative to the axis. The roller 12, resting against the belt 8, pulls it up and the spindle 2 begins to rotate. At this time, the next node is loaded at the loading position with the spindle disconnected. After the workpiece is heated to a certain temperature, the gear 16 is engaged, the chuck 1 rotates, the node 15 becomes at the welding position. A welding machine (not shown) is installed above this position. After welding, the faceplate 1 is rotated, the welded assembly is removed, new blanks are installed and the process is repeated. Thus, at the loading position, an automatic, disabling the rotation of the spindle, is made, which improves the performance of the manipulator and simplifies its management. Claims of the invention A multi-position welding manipulator comprising a rotary faceplate mounted on the base with spindles at each position, a rotational drive for the faceplate and rotation of the spindle, and a device for deactivating the rotation of the spindle at the loading position, characterized in that, in order to improve performance by ensuring automatic spindle shutdown at the loading position, on the output shaft of the drive along the axis of rotation of the faceplate and on the spindle x there are mounted pulleys with respectively each pulley u indedel and faceplate strap, and the device for deactivating spindle rotation at the loading position is designed as a cam fixed on the base along the axis of rotation of the faceplate with a concave surface on the side of the loading position and pivotally mounted on the faceplate according to each position of the spring-loaded two-arm levers for tensioning belts, one of the shoulders of each of which is installed with the ability to interact with the cam, and the other with the corresponding belt.
