Hydraulic servo oil cylinder with guiding and positioning mechanism

The hydraulic servo oil cylinder with the guiding and positioning mechanism comprises a cylinder body, one end of the cylinder body is provided with a first connecting end, the other end of the cylinder body is connected with a cylinder cover in a threaded mode, a piston is arranged at one end in the cylinder body in a sliding mode, and a buffering spring in a buffering assembly stretches out and draws back to drive a round limiting plate to slide in a round sliding groove. The impact force of the piston on the guide sleeve is reduced through the cooperation of the buffer gasket and the buffer assembly, the lubrication degree between the piston rod and the guide sleeve is increased through the graphite gasket, meanwhile, the guide sleeve and the piston rod are sealed, and the cylinder cover is in threaded connection with the cylinder body, so that the service life of the piston rod is prolonged. The internal parts of the buffer assembly can be conveniently replaced and maintained when the internal parts of th
