Manipulator for marking machine

The invention relates to a manipulator for a marking machine. The manipulator for the making machine comprises a lifting cylinder, and an output end of the lifting cylinder is connected to a beam. Two motors are symmetrically arranged at the two output ends of the lifting cylinders on the beam, output ends of the motors are connected to screws through drive mechanisms and can drive the screws to rotate, guide rails are symmetrically arranged on the beam and are slidably connected with sliding mechanisms, and the sliding mechanisms are connected with threads of the screws and a clamping mechanism. The manipulator for the marking machine has the advantages of simple structure and convenience in operation. Down and left and right movements are respectively realized by the aid of the lift cylinder and the drive mechanism, and an arc clamp is suitable for cylinders of different size. A curved panel is hinged at one end of the clamp to ensure that the cylinder surface is not damaged while being clamped, the clamping process is safe, secure and reliable, the marking machine is of high degree of automation, so that time, effort and costs are saved and working efficiency is improved.
