Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the drawings.

[0043] Reference figure 2 , 4 , A split-type, small-stroke and heavy-load non-stationary hydraulic cylinder that can be precisely digitized, including a motor and a hydraulic cylinder. The motor includes a motor housing 16, a motor front cover 6, a motor rear cover 10, a motor stator coil 17 and a motor Rotor 7, the two ends of the motor rotor 7 are respectively connected to the front and rear end covers of the motor through bearings 15. The hydraulic cylinder includes a cylinder block 12, a hydraulic cylinder front cover 11, a hydraulic cylinder rear cover 4 and a working piston 2. One end of the working piston 2 is provided with a piston rod 1, and the piston rod 1 is set through the front end cover 11 of the hydraulic cylinder. The front end cover 11 of the hydraulic cylinder is provided with a through hole communicating with the atmosphere. The special feature is that it also in...

Abstract

The invention relates to the technical field of hydraulic cylinders, in particular to a split type shore-stroke heavy-load precise digital non-station hydraulic cylinder. The problems that weight is heavy, manufacturing cost is high, loading procedures are not precise enough, and direct operation portions are not light and handy enough exist in the prior art. In order to overcome the defects in the prior art, the split type shore-stroke heavy-load precise digital non-station hydraulic cylinder comprises a motor and a hydraulic cylinder, wherein the hydraulic cylinder comprises a cylinder body, a hydraulic-cylinder front end cover, a hydraulic-cylinder rear cover and a working piston. The split type shore-stroke heavy-load precise digital non-station hydraulic cylinder further comprises a screw small piston, the piston end of the screw small piston is installed inside a piston barrel, the outer end of the piston barrel and the hydraulic-cylinder rear cover are provided with through holes, and the two through holes are communicated through a connection oil pipe. The split type shore-stroke heavy-load precise digital non-station hydraulic cylinder obviously reduces equipment cost and equipment weight, and is simple in structure and low in leakage.

Description

Technical field: [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a split type non-stop hydraulic cylinder with small stroke and heavy load that can be precisely digitized. Background technique : [0002] The core of shearing machine, bending machine, stamping machine, die-casting machine, die-casting machine, riveting gun and other machinery is to provide small stroke and high pressure movement. Under the action of this form of power, the workpiece is sheared, bent, punched, compacted, deformed, etc. This kind of movement with small stroke and high pressure is generally powered by inertia wheel or hydraulic station. The experimental equipment with small stroke and heavy load is mostly powered by a hydraulic station, and the loading of the experimental piece is realized through various control valves. [0003] There are two most common ways for the above-mentioned equipment to realize the movement of small stroke and heavy lo...
