Manipulator used for griping high-temperature workpieces

Abstract

The invention discloses a manipulator used for griping high-temperature workpieces. The manipulator comprises a first grip pawl and a second grip pawl which are opposite to each other and hinged through a rotating pin; the manipulator further comprises a manipulator mounting plate and a power cylinder, the rotating pin and the power cylinder are arranged on the manipulator mounting plate, and a driving block used for driving same ends of the first grip pawl and the second grip pawl to move oppositely is arranged on a piston rod of the power cylinder, and a cooling hole is arranged in the rotating pin. Only one rotating hinged point is arranged on the griping manipulator, so that the manipulator is simple in structure and low in cost, a manipulator joint is less prone to being jammed or loosened, the power cylinder is away from the front half section in distance, service life of the cylinder is prolonged, and the high-temperature workpieces can be gripped stably and reliably.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a manipulator for grabbing high-temperature workpieces. Background technique [0002] In the field of workpiece handling and automatic loading and unloading, the flexibility of the workpiece grabbing manipulator and the reliability of grabbing the workpiece are very important. Several types of manipulators currently in use are pneumatic or electric workpiece grabbing manipulators with multiple rotation nodes. More, make manipulator self weight bigger and manufacturing cost on the high side. [0003] Moreover, it is not suitable for the working condition of automatic loading and unloading of hot forging with high temperature, because the temperature of the high-temperature forging environment changes greatly, and when there are many joints of the manipulator, the manipulator will be stuck or loosened due to thermal deformation, resulting in insufficient feeding. Stab...

[0002] In the field of workpiece handling and automatic loading and unloading, the flexibility of the workpiece grabbing manipulator and the reliability of grabbing the workpiece are very important. Several types of manipulators currently in use are pneumatic or electric workpiece grabbing manipulators with multiple rotation nodes. More, making the manipulator itself heavier and the manufacturing cost higher

[0003] Moreover, it is not suitable for the working condition of automatic loading and unloading of hot forging with high temperature, because the temperature of the high-temperature forging environment changes greatly, and when there are many joints of the manipulator, the manipulator will be stuck or loosened due to thermal deformation, resulting in insufficient feeding. Stability, material drop and clamping force mutation, etc., affect the reliability of automatic loading and unloading, and seriously restrict the realization of automation in the hot forging industry
