Embodiment 1

[0016] Such as Figure 1-2 As shown, a hexagonal inner piston rod hydraulic cylinder includes a cylinder body 1, a piston 2, a piston rod 3 and a cylinder bottom 4. The piston 2 is slidably arranged in the cylinder body 1, and one end of the piston rod 3 is arranged On the piston 2, the other end of the piston rod 3 extends out of the cylinder 1, the end of the piston rod 3 away from the piston 2 is provided with a threaded connection portion 301, and the cylinder bottom 4 is fixedly connected to One end of the cylinder 1 away from the threaded connection portion 301, one end of the piston rod 3 is provided with a disassembly hole 302 for matching tools and driving the piston rod 3 to rotate. The disassembly hole 302 is located at the piston rod 3 near the cylinder bottom 4 One end.

[0017] The cross-sectional shape of the disassembly hole 302 is a polygonal structure. The disassembly hole 302 is an inner hexagonal hole.

[0018] When the above-mentioned hexagonal inner piston ...

Embodiment 2

[0020] The difference between embodiment 2 and embodiment 1 lies in: image 3 As shown, the cross-sectional shape of the disassembly hole 302 is a semicircular structure. Setting a wrench that matches the cross-sectional shape of the disassembly hole 302 can make the piston rod 3 rotate, thereby disassembling the piston rod 3 and the connecting device.

Abstract

The present invention relates to the technical field of hydraulic cylinder equipment, in particular to a hexagonal piston rod hydraulic cylinder, comprising a cylinder body, a piston, a piston rod and a cylinder bottom, the piston is slidably arranged in the cylinder body, and the piston rod One end is arranged on the piston, the other end of the piston rod protrudes from the cylinder, the end of the piston rod away from the piston is provided with a threaded connection, and the cylinder bottom is fixedly connected to the cylinder away from the cylinder by screws. One end of the threaded connection, one end of the piston rod is provided with a disassembly hole for cooperating with the tool and driving the piston rod to rotate. When the hexagonal piston rod hydraulic cylinder of the present invention is assembled and disassembled, a Disassembly hole, and by placing the tool in the disassembly hole, turning the tool drives the piston rod to rotate together, so as to complete the assembly and disassembly between the threaded connection part of the piston rod and the equipment, without having to disassemble the entire equipment, which can save a lot of time and manpower.

Description

Technical field [0001] The invention relates to the technical field of hydraulic cylinder equipment, in particular to a hydraulic cylinder with a hexagonal inner piston rod. Background technique [0002] Hydraulic cylinders are widely used, and there are hydraulic cylinders in equipment from all walks of life. In some industries, hydraulic cylinders work frequently, so hydraulic cylinders need to be disassembled and repaired frequently. Conventional hydraulic cylinders usually have a flat groove milled at the front end of the threaded connection of the rod end. When disassembling, use a wrench to clamp the piston rod in the flat groove to connect the piston rod to the equipment. This structure is suitable for disassembly and assembly. The situation of interference can proceed normally. If the front end of the hydraulic cylinder interferes with the equipment and the wrench cannot be inserted in, it is necessary to remove the interference part of the equipment, and reinstall the ...
