[0028] The present invention will be described in detail below in conjunction with the drawings.
[0029] Such as figure 1 As shown, the horizontal servo cylinder 1 of the present invention includes a cylinder block 2, a cylinder head 3, and a piston rod 4. A guide sleeve of the cylinder head 4 is provided with one or more pairs of up and down asymmetric oil cushions along the axial direction. The piston rod 4 The lower oil pad is a support oil pad 6, which is composed of an oil cavity 61, a center oil inlet 62, an oil sealing edge 63, and an oil return groove 64. The oil pad on the upper side of the piston rod 4 is a counter-force oil pad 5, which is composed of an oil cavity 51, a central oil inlet 52, an oil sealing edge 53, and an oil return groove 54. The independent oil supply system 9 simultaneously feeds pressure oil to each oil pad. The oil supply system 9 is composed of an oil tank 91, a hydraulic pump 92, an overflow valve 93 and a filter 94. The oil outlet of the hyd...
