Hydraulic cylinder of non - welding cylinder bottom structure

The utility model provides a hydraulic cylinder of non - welding cylinder bottom structure, includes cylinder bottom, cylinder barrel assembly, piston assembly, piston rod assembly, uide bushing subassembly, connecting bolt, connecting bolt, nut, there are cylinder bottom flange, uide bushing flange in cylinder barrel assembly's both ends welded connection respectively, and wherein cylinder bottom flange adopts bolted connection structural connection cylinder bottom, and uide bushing flange adopts bolted connection structural connection uide bushing subassembly. Its advantage is that hydraulic cylinder's cylinder and cylinder bottom adopts split type structure, adopts bolted connection's mode with the cylinder bottom when cylinder is connected, and the bolted connection structure has replaced the cylinder bottom welding process of traditional hydro -cylinder, can avoid owing to quality problems such as welding seam fracture that weld defects, welding strength caused less than, welding technique etc. Welding s
