Problems solved by technology

[0003] Due to the frequent reciprocation of the piston rod of the above-mentioned oil pressure buffer or oil pressure stabilizer, after a long time of use, the piston rod will take the hydraulic oil in the internal pressure cylinder out of the oil seal end. If the oil volume of the internal pressure cylinder is reduced, there will be problems such as unstable speed or weakened cushioning force. It needs to be repaired and refilled with oil. This will bring inconvenience to the production and users of the oil pressure buffer or oil pressure stabilizer, and consume a lot of time and money. , higher maintenance cost

Abstract

The invention relates to a connected auxiliary oil tank structure. The connected auxiliary oil tank structure comprises a cylinder body of an oil pressure buffering device, the end, far away from a piston rod, of the cylinder body is provided with a containing cavity, and an oil tank rear cover in threaded connection with the cylinder body is arranged in the containing cavity. When the oil tank rear cover is rotationally connected with the cylinder body, the oil tank rear cover is matched with the cylinder body so that the containing cavity can form a closed oil storing cavity, and the oil tank rear cover is further provided with an oil delivery channel enabling the oil storing cavity to be communicated with the interior of the cylinder body. According to the connected auxiliary oil tank structure, hydraulic oil reserved in the oil storing cavity is supplemented to the interior of the cylinder body of the oil pressure buffering device by screwing in the oil tank rear cover so that it can be guaranteed that the oil pressure buffering device can work for a long time at the optimal stable speed or in a buffering state, after-sales services and maintenance of the oil pressure buffering device are avoided for a longer using time, the service life of the oil pressure buffering device is substantially prolonged, and using and maintaining cost is reduced.

Description

technical field [0001] The invention relates to the technical field of oil pressure buffers, in particular to a connected auxiliary oil tank structure and an oil pressure buffer using the same. Background technique [0002] Oil pressure buffer (speed stabilizer, damper) is a hydraulic device that converts impact kinetic energy into hydraulic oil heat energy, realizes linear deceleration of objects, and finally stops smoothly. It is usually widely used in automatic machinery such as manipulators, pneumatic cylinders, speed-adjustable drilling machines, grinding machines, cutting machines, glasses machinery, drilling machinery, woodworking machinery, lock making equipment, watch machinery, cutting machines, etc. See the oil pressure shock absorber disclosed by the patent announcement number CN204140749U, the oil pressure shock absorber does not have pressure adjustment, and includes an external pressure cylinder, an internal pressure cylinder, a pressure storage sponge, a rear...
