The invention discloses a precise clamping rotary hydraulic manipulator. The precise clamping rotary hydraulic manipulator comprises a bearing base, a mechanical arm and a clamping manipulator; a rotating table is mounted at the top of the bearing base; the rotating table comprises a rotating motor, and a rotating disc in transmission connection with the rotating motor; a first hydraulic cylinderis mounted at the top of the rotating table; the mechanical arm is mounted at the top of the first hydraulic cylinder; a second hydraulic cylinder is fixedly mounted at one end of the mechanical arm;and a driving motor is mounted at an output end of the second hydraulic cylinder. The precise clamping rotary hydraulic manipulator can realize the rotation and extension adjustment to flexibly move to an object to be clamped so as to effectively improve the manipulator clamping precision; and through arrangement of a negative-pressure cavity and a negative-pressure sucker on a mechanical jaw, a negative-pressure absorption fixing principle is used for achieving firmer and more stable object clamping by the mechanical jaw, so that the clamping damage degree of the object is reduced, and the practicability is higher.

A loader-type heavy construction machine has a chassis and work equipment. The work equipment includes two parallel arms articulated relative to the frame, a bucket articulated relative to the arms, a set of link rods forming, with a portion of the bucket and of the arms, a deformable parallelogram, and a bucket actuator capable of being controlled to cause deformation of the deformable parallelogram so as to orient the bucket with respect to the arms. A cam is moved by a connecting bar connected at one end to the deformable parallelogram so that the position of the cam is dependent on the orientation of the bucket with respect to the chassis. The cam interfaces with an hydraulic circuit to ensure that the bucket is maintained in a position preventing it from accidentally tipping over backwards, regardless of commands exerted on an hydraulic manipulator by a driver of the machine.

The invention discloses a rotary hydraulic mechanical hand body of a hydraulic large-sized mechanical hand. The rotary hydraulic mechanical hand body of the hydraulic large-sized mechanical hand comprises a connecting base, a rotary oil cylinder, a mechanical hand oil cylinder outer cavity, an ear-ring type mechanical hand oil cylinder piston rod, a mechanical finger base and mechanical fingers, the connecting base is fixed to the left end of a shell of the rotary oil cylinder through screws, a rotary shaft of the rotary oil cylinder and the mechanical hand oil cylinder outer cavity are integrated, the mechanical finger base is fixed to the right end of the mechanical hand oil cylinder outer cavity, the mechanical finger base is movably connected with the middle of the mechanical fingers, the left ends of the mechanical fingers are connected with the ear-ring type mechanical hand oil cylinder piston rod, and a plurality of skid-resistant burrs are arranged on the mechanical fingers. By means of the mode, the rotary hydraulic mechanical hand body of the hydraulic large-sized mechanical hand is under pure hydraulic drive, each movable joint is large in movable torque, the rotary hydraulic mechanical hand body can be used in severe industrial environment, the requirements for protecting levels are low, the working force of the rotary hydraulic mechanical hand body is much higher than that of electrically-driven mechanical hands of the same level, and the cost of the rotary hydraulic mechanical hand body is much lower than that of the electrically-driven mechanical hands of the same level.

The invention discloses a hydraulic manipulator comprising a tank body; a rotating boss and an oil filling port are formed in the tank body; the rotating boss is provided with a mounting part connected with a big arm through a mounting shaft; the big arm is hinged with one end of a forearm and is fixedly provided with a big arm cylinder; and the other end of the forearm is hinged with a gripper. When being used, the hydraulic manipulator can be mounted in a required place, and a required action is set through an operation panel as required and is stored. When the hydraulic manipulator is used, only a power supply is needed to be started every time, and a set action command is selected to operate; the inner side of each of two claws is provided with two cushion blocks, so that the grasping force of the gripper can be effectively increased; and an oil tank, a motor, a gear pump and an electric control mounting region are arranged inside the tank body, so that the structure of the hydraulic manipulator is simplified, and meanwhile, the hydraulic manipulator has the characteristic of simple appearance.

The auxiliary hydraulic set for great tonnage press consists of floating movable platform attached to the press, platform seat and manipulator suspended over the platform seat. The auxiliary hydraulic set features that the floating movable platform is set on the tracks on the platform seat via four rollers and support springs and has one connected translation hydraulic cylinder to constitute displacing mechanism, the platform seat has one demolding stage hole and the manipulator is operated and controlled with the lifting hydraulic cylinder, pushing hydraulic cylinder and clamping hydraulic cylinder over the hole and the supporting hydraulic cylinder below the hole. The completely hydraulic structure can realize the horizontal displacement of the floating platform and the mechanical displacement and demolding of large pressed member.

The invention discloses a hydraulic manipulator. The hydraulic manipulator comprises a base, a rack arranged on the top of the base, a mechanical arm component connected with the rack and a clamping mechanism connected with the mechanical arm component through a fixing plate, wherein the mechanical arm component comprises a first mechanical arm and a second mechanical arm; the first mechanical arm is rotatably matched with the rack; and the second mechanical arm is rotatably matched with the first mechanical arm. The hydraulic manipulator is convenient to use; the whole structure is simple; the work efficiency is high; and the hydraulic manipulator is flexible and reliable while clamping workpieces.

The invention discloses a master-slave type artificial muscle joint system with position / force two-way feedback. The system is composed of a master joint system with a pneumatic artificial muscle driving mode and a slave joint system with a hydraulic artificial muscle driving mode. A positional voltage signal of the master joint system can be fed back to the input terminal of the slave joint system, so that the slave joint system tracks the positional voltage signal to carry out corresponding rotation angle action; meanwhile, a torque voltage signal of the slave joint system can be fed back tothe input terminal of the master joint system, so that the master joint system tracks the torque voltage signal to make action. When the master-slave type artificial muscle joint system works, compatibility with the seawater environment during operation is high; no environmental pollution is caused. With the master and slave controlling, a hydraulic manipulator can move with the operator's arm synchronously, so that the operation becomes simple. The stress of the driven hydraulic artificial muscle joint can be fed back to the driving pneumatic artificial muscle joint, so that the operator hasthe intuitive experience of the stress on the artificial muscle joint.
