Изобретение относитс к машиностроению , в частности к конструкци м манипул торов , и может быть использовано дл автоматизации технологического оборудовани термообработки.The invention relates to mechanical engineering, in particular to manipulator structures, and can be used to automate heat treatment process equipment.

Известен захват, содержащий корпус с зажимным рычажным механизмом и сжобу, св занную со штоками силовых цилиндров. При перемещении штоков проиоходит разведение или смыкание губокюA gripper is known, comprising a housing with a clamping lever mechanism and a seal associated with the rods of the power cylinders. When moving stocks proceeds dilution or sponge closure

Однако известный захват не может обеспечить одновременного надежного зажати нескольких заготовок с различными линейными размерами.isHowever, the known grip cannot provide simultaneous reliable clamping of several blanks with different linear dimensions.

Цель изобретени - повышен 1е надежности работы при одновременном зажатии нескольких заготовок с различными линейными размерами.. 20The purpose of the invention is to improve the reliability of the operation while simultaneously clamping several blanks with different linear dimensions. 20

Указанна цель достигаетс тем, что в захвате скоба выполнена из двух шарнирно соединенных частей, на которых выполнены фигурные пазы, причем в каждомThis goal is achieved by the fact that, in the gripper, the bracket is made of two pivotally connected parts, on which shaped grooves are made, each having

фигурном пазу шарнирно установлены рычаги зажимного механизма.the clamping mechanism levers are hinged in the shaped groove.

На фиг. 1 изображен захват, общий вид; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the capture, general view; in fig. 2 shows section A-A in FIG. one.

Захват содержит приводные цндцндры 1, установленные на корпусе 2, скобу 3, выполненную из двух частей, соединенных шарниром 4. Кажда часть скобы 3 закреплена шарнирно на одном из штоков 5 цилиндров 1 и может быть св зана пружиной 6 с корпусом 2. На подвижной скобе 3 выполнены, например, три фигурные паза.The gripper contains drive centers 1 mounted on housing 2, bracket 3, made of two parts connected by a hinge 4. Each part of bracket 3 is fixed pivotally on one of the rods 5 of cylinder 1 and can be connected by spring 6 to case 2. On a movable bracket 3, for example, three shaped grooves.

Claims

The clamping lever mechanism consists of two shoulders levers 7, which are arranged in pairs in the shaped grooves of the bracket and fixed to the housing 2 on the axles 8. The levers 7 can be made adjustable in length. The end of one arm of the lever 7 is made with a rounded surface 5, the center of which is rimmed with respect to axis 8. On the other shoulder there are mounted clamping jaws 9, which can be made self-weeding 11osh 11 tc1; and (relative to the rims 7 axes J. O Between the axis of symmetry and the bottom of the adjacent fig. The first slots of the bracket 3 are divided by a rod in relation 3, i.e. the point of application of force is 2.5 to 3 times away from the axis of symmetry of the gripper Farther than from the axis of symmetry of the outermost The body of the south organ. The grip works as follows. Stocks 5 cylinders 1 n The bracket is stirred in the 3 p direction of the levers 7. The springs 6 are then stretched. The bracket is engaged by the planes B of the shaped grooves on the surface B of the double-arm levers 7, which are clamped to the axes 8 and the clamping jaws O are clamped to fully clamp all the blanks In this case, the hinge joint 4 is moved along the gripping axis. The springs 10 regulate the force and position of the jaws 9 in the presence of ovals, 1UPLUS, burrs, etc. on the workpieces. First of all, the levers 7 capture the largest diameter workpiece 9. If this billet is captured by levers located on average pitch scoops 3, then the extreme pairs of levers 7 continue to compress the sponges 9, as under the influence of the rods 5 both parts of the clevis rotate at the hinge 4. At the same time the clevis ends are mixed in the direction of the arms 7 until the rest of the workpieces are fully clamped, the hinge 4 is moved along the gripping axis in the direction of the iii-linings, and the protrusions of the middle groove slide B along the rounded edges of the B ends of the levers 7, retaining the clamping force. When reversing the rods 5, the bracket 3 acts by the projections G on the levers 7, turning them on the axis 8. As a result, the levers 7 move the jaws 9 apart and release the blanks. The proposed gripper design ensures reliable multi-point clamping of workpieces with both small and wide tolerances with an untreated surface, such as casting and rolling, as well as their transfer to the subsequent heat treatment operation. Claims of the invention The gripper comprising a housing with a clamping lever mechanism and a clamp associated with the rods of the power cylinders, characterized in that, in order to increase reliability while simultaneously clamping several blanks with different linear dimensions, the clamp is made of two hinged parts, on which the shaped grooves are made, and in each shaped groove the levers of the clamping mechanism are installed.
