Easy to disassemble hydraulic buffer device

Abstract

The invention discloses an easy-to-dismount hydraulic buffer device, which comprises a threaded main body and a core body, wherein one end of the threaded main body is a sealed end; the upper end of the core body is in abutted joint with the sealed end of the threaded main body; a sealing gasket is arranged at the abutted joint position; a spiral groove piston and an oil seal are arranged inside the core body; a first oil storage space is formed between the sealed end of the threaded main body and the spiral groove piston; a second oil storage space is formed between the spiral groove piston and the oil seal; a spiral groove is formed in the spiral groove piston; an oil passing part is fixedly arranged inside the core body; an annular groove is formed in the oil passing part; two sealing rings are arranged on the oil seal. The easy-to-dismount hydraulic buffer device has the advantages that the dismounting is easy; a user can repair the easy-to-dismount hydraulic buffer device by self; good sealing performance after the repair can also be ensured; the sealing rings are arranged on the oil seal; if the sealing ring has poor sealing effects after being used for a long time, the sealing ring can be conveniently replaced; other components do not need to be replaced; the time and the labor are saved; the use cost is reduced.

Description

technical field [0001] The invention relates to a hydraulic buffer device, in particular to an easily detachable hydraulic buffer device. Background technique [0002] The hydraulic buffer device relies on hydraulic damping to buffer and decelerate the objects acting on it to a stop, which plays a certain degree of protection. It is suitable for mechanical equipment such as lifting transportation, elevators, metallurgy, port machinery, railway vehicles, etc. It is used as a safety buffer device to prevent mechanical damage caused by hard collisions during work. [0003] The clamp bottle hydraulic buffer device used when making glass bottles is also such a device, because in the process of manufacturing glass bottles, the clamp bottle mechanism of the bottle machine is used as a pneumatic manipulator to complete the "clamp bottle in" and "clamp bottle out" of the product. The action of "clamping bottle in" and "clamping bottle out" not only requires fast and stable movements...

AI Technical Summary

Problems solved by technology

[0004] However, the current clamp bottle hydraulic buffer device is difficult to restore after disassembly, and cannot be repaired without special equipment. If the clamp bottle hydraulic buffer device fails to buffer, it is usually scrapped directly or returned to the manufacturer for repair. The cushioning device can't play a good cushioning effect, usually because the internal rubber parts have been used for a long time and have problems such as oxidation. However, it is inconvenient to replace such parts, and it is difficult to ensure the sealing after replacement, which leads to the need to combine with other parts. Replacement together is a waste of resources
