[0018] The present invention will be described in detail below with reference to the drawings.
[0019] Such as figure 1 As shown, the horizontal servo cylinder of the present invention includes a cylinder block 2 and a piston rod 1. One or more pairs of asymmetrical oil cushions are arranged along the axis on the cylinder guide sleeve, wherein the oil cushion on the lower side of the piston rod 1 is the support The oil pad 10 and the supporting oil pad 10 are composed of an oil cavity, a central oil inlet hole, an oil sealing edge and a supporting oil return groove 11. The oil pad on the upper side of the piston rod 1 is a reaction force oil pad 5, which is composed of an oil cavity, a central oil inlet hole, an oil sealing edge, and a reaction force oil return groove 4. An independent oil supply system is used to feed pressure oil to each oil pad at the same time. The oil supply system includes an oil tank 8, a hydraulic pump 7, a proportional relief valve 9 and a filter 6. Th...
