Manipulator for grabbing high-temperature steel plate spring

The invention belongs to the field of industrial automation, and particularly relates to a manipulator for grabbing a high-temperature steel plate spring. The manipulator comprises a base, a lifting strut, a big arm, a medium arm, an upper small arm, a lower small arm, a T-shaped arm, rotary motors of the big arm, the medium arm and the small arms, swing hydraulic cylinders of the lower small armand the T-shaped arm, and first and second clamping devices. The lifting strut is fixed on the base; the big arm is connected with the lifting strut, the medium arm is connected with the big arm, theupper small arm is connected with the medium arm, the upper small arm is connected with the lower small arm, and the T-shaped arm is connected with the lower small arm; and the rotary motors of the big arm and the medium arm are fixed on the big arm, the rotary motors of the small arms are fixed on the medium arm, two ends of the swing hydraulic cylinder of the lower small arm are connected with the upper and lower small arms respectively, two ends of the swing hydraulic cylinder of the T-shaped arm are connected with the lower small arm and the T-shaped arm respectively, and the first and second clamping devices are connected with two ends of the T-shaped arm respectively. The high-temperature steel plate spring is grabbed through the manipulator, so that labor intensity of workers is reduced and the automatic level is improved.
