Description
Technical Field
The utility model relates to the technical field of hydraulic oil cylinders, in particular to a high-reliability spring cylinder assembly.
Background
The plunger cylinder is a structural form of a hydraulic cylinder which can only move in one direction, a single plunger cylinder can only move in one direction, and the reverse direction depends on external force, so that the operation is complex, the working efficiency is low, and the spring cylinder resets the piston rod by utilizing the resetting function of the spring, so that the problem that the plunger cylinder cannot reset can be solved by mutually combining the spring cylinder and the plunger cylinder.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects and provide a spring cylinder assembly with simple and reliable structure, convenient operation and high reliability.
The purpose of the utility model is realized as follows:
a high-reliability spring cylinder assembly body comprises a cylinder barrel, a plunger, a spring and a guide sleeve, wherein the plunger is arranged at the front end of the cylinder barrel, the guide sleeve is arranged outside the rear end of the plunger, the plunger is guided by the guide sleeve, and the plunger and the cylinder barrel are communicated with each other and are not in contact with each other; the guide sleeve and the cylinder barrel are fixed through a flange; springs are arranged in the plunger and the cylinder barrel, the front ends of the springs are fixed with the plunger, a spring guide post with the length direction consistent with the length direction of the springs is arranged in the cylinder barrel, and the part of the springs, which are positioned in the cylinder barrel, is sleeved on the spring guide post; the front end of the plunger is provided with a plunger head; the rear end of the cylinder barrel is provided with a rear cover; the rear cover is provided with an oil port.
According to the spring cylinder assembly body with high reliability, the flange is fastened through the hexagon socket head cap screw.
Compared with the prior art, the utility model has the beneficial effects that:
according to the spring cylinder assembly body with high reliability, the plunger is arranged at the front end of the cylinder barrel, the guide sleeve is arranged outside the rear end of the plunger and is guided by the guide sleeve, and the plunger is communicated with the cylinder barrel and is not contacted with the cylinder barrel; the plunger and the cylinder are internally provided with the spring for resetting, hydraulic oil is injected into the cylinder, the spring pushes the plunger to move forwards after being extruded, the plunger is pulled back to the original position through the automatic resetting function of the spring when the hydraulic oil is discharged, external force is not required to be manually applied to the plunger to reset the plunger, and the plunger resetting device is simple and reliable in structure and convenient to operate.
Drawings
Fig. 1 is a schematic structural view of a highly reliable spring cylinder assembly according to the present invention.
Fig. 2 is a cross-sectional view of fig. 1.
Fig. 3 is a side view of fig. 1.
Wherein: the device comprises a cylinder barrel 1, a spring 2, a spring guide post 3, a guide sleeve 4, a plunger 5, a plunger head 6, a rear cover 7, a flange 8, an inner hexagon bolt 9 and an oil port 10.
Detailed Description
Referring to fig. 1 to 3, the highly reliable spring cylinder assembly according to the present invention includes a cylinder barrel 1, a plunger 5, a spring 2, and a guide sleeve 4, wherein the plunger 5 is disposed at the front end of the cylinder barrel 1, the guide sleeve 4 is disposed outside the rear end of the plunger 5, the plunger 5 is guided by the guide sleeve 4, and the plunger 5 and the cylinder barrel 1 are communicated with each other and do not contact each other; the guide sleeve 4 and the cylinder barrel 1 are fixed through a flange 8; a spring 2 is arranged in the plunger 5 and the cylinder barrel 1, the front end of the spring 2 is fixed with the plunger 5, a spring guide post 3 with the length direction consistent with the length direction of the spring 2 is arranged in the cylinder barrel 1, and the part of the spring 2 positioned in the cylinder barrel 1 is sleeved on the spring guide post 3; the front end of the plunger 5 is provided with a plunger head 6; the rear end of the cylinder barrel 1 is provided with a rear cover 7; the rear cover 7 is provided with an oil port 10;
further, the flange 8 is fastened by hexagon socket head cap bolts 9.
The working principle of the high-reliability spring cylinder assembly body is as follows: hydraulic oil enters the cylinder barrel 1 from the oil port 10, the spring 2 is pressurized by the hydraulic oil, the plunger 5 is pushed to move forwards by the compression of the spring 2, and the plunger 5 automatically resets due to the resetting function of the spring 2 when the hydraulic oil is discharged.
In addition: it should be noted that the above-mentioned embodiment is only a preferred embodiment of the present patent, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of the present patent.
