A hoisting mechanism of an asymmetric forging manipulator with a pitch linear drive

Abstract

Disclosed is a lifting mechanism of an asymmetric-type forging operator of a prostrate linear actuator. A nippling lever and a front supporting rod are fixedly connected, the lower ends of front suspension rods are hinged to the front supporting rod while the upper ends of the same are connected with the lower ends of front connecting members, the middle portions of the front suspension rods are hinged to the front ends of front-rear buffering linear actuators, the rear ends of the front suspension rods are connected with a middle connecting rod of the nippling rod, a moving frame is connected with the upper ends of the front connecting members and a front sliding rod sleeve, front left-right linear actuators at two ends of a front sliding rod are fixedly connected with a front lifting arm, a left-right buffering linear actuator is fixedly connected on the nippling lever, lifting linear actuators are connected with a lower arm of the front lifting arm and a rack, synchronous rods are connected with an upper arm of the front lifting arm and a rear lifting arm, rear left-right linear actuators are fixedly connected on two sides of the rear lifting arm, moving ends of the rear left-right linear actuators are connected with a rear sliding rod, the left side of the rear lifting arm is connected with a rear connecting member, the rear connecting member is connected with the upper end of a left prostrate linear actuator, the lower end of the rear connecting member is connected with a rear supporting rod, the right side of the rear lifting arm is connected with the upper end of a right prostrate linear actuator, and the lower end of the rear lifting arm is connected with the rear supporting arm. The lifting mechanism has the advantages of high bearing capacity, easiness in mounting and the like.

Description

technical field [0001] The invention relates to a mechanical engineering device, in particular to a lifting mechanism of a forging manipulator. Background technique [0002] The forging manipulator is one of the indispensable and important equipment in the automatic forging operation, which plays an important role in improving production efficiency and ensuring processing quality. To complete a complete set of forging procedures, the forging manipulator needs to realize seven forging operation functions including jaw clamping, tong bar rotation, tong bar lifting, tong bar pitching, tong bar lateral movement, tong bar swing, and cart travel. Among them, the three actions of jaw clamping, clamp rod rotation, and cart walking are independent from each other in structure, and are respectively driven by motors or hydraulic cylinders. The clamp realizes the clamping and rotating functions of the workpiece, and the cart undertakes the traveling function. The action is realized by ...

Problems solved by technology

Among them, the parallel link type forging manipulator has high motion decoupling and is easy to control, but most parallel link type forging manipulators only contain a single pitching hydraulic cylinder, such as German patent DE20108277, Chinese patents 201010543863.5, 201010133714.1, 201210420607.6, etc. The manipulator clamping capacity of this structure is not great

In Chinese patents 201010193620.3 and 201210182110.5, although there are two pitching hydraulic cylinders, the pitching hydraulic cylinders are either placed in the middle of the synchronous rod or directly connected to the frame. reduce
