Description

TECHNICAL FIELD

[0001] The utility model relates to a micro pressure recycling oil supply tank, and particularly relates to a micro pressure recycling oil supply tank with an oil return confirmation mechanism suitable for full-automatic equipment. BACKGROUND

[0002] For a full-automatic bearing vibration measuring device, a dynamic pressure spindle needs to be supplied with oil for lubrication. Specifically, the dynamic pressure spindle is a high-precision spindle, which needs to be injected with lubricating oil to form an oil film when rotating. The full-automatic bearing vibration measuring device is in an automatic operation state most of the time and is unattended.

[0003] The prior art full-automatic bearing vibration measuring device generally does not have an oil return confirmation mechanism in the oil circuit system. When the oil supply tank has a fault, such as pump failure, oil circuit blockage, or insufficient oil in the tank, the spindle will rotate in a state without lubricating oil, which will cause the spindle to wear. The prior art also has an oil supply tank with an oil return confirmation mechanism, but has problems such as complex structure, insufficient stability, high cost, etc. SUMMARY

[0004] The utility model provides a micro pressure recycling oil supply tank with an oil return confirmation mechanism, which aims to overcome the above-mentioned deficiencies in the prior art, and realizes the oil return confirmation function with a simple structure, stable performance, and low cost.

[0005] The technical solution of the utility model is as follows: a micro pressure recycling oil supply tank with an oil return confirmation mechanism, which comprises an oil tank body, a first oil return box and a second oil return box are arranged on the top of the oil tank body, a second cover is arranged on the top of the oil tank body where the first oil return box and the second oil return box are located, a first oil float and a second oil float are arranged on the second cover, the first oil float and the second oil float respectively extend into the first oil return box and the second oil return box, the first oil return box and the second oil return box are respectively connected to a fourth oil pipe and a fifth oil pipe through joints on the second cover, the fourth oil pipe and the fifth oil pipe are respectively connected to a dynamic pressure spindle oil return end, and a drain hole communicating with the inside of the oil tank body is arranged on the first oil return box and the second oil return box. The oil return of the dynamic pressure spindle flows into the first oil return box and the second oil return box through the fourth oil pipe and the fifth oil pipe. When the oil return box is full, the floating balls of the first oil float and the second oil float will float up. At this time, the oil float feeds back a normal oil return signal of the oil circuit (i.e., a signal that the oil amount in the oil return box is sufficient). When the oil circuit stops supplying oil, the first oil return box and the second oil return box will have no oil return, the drain hole will drain the oil in the oil return box, and the floating balls of the first oil float and the second oil float will fall back to the bottom. At this time, the oil float feeds back an abnormal oil return signal of the oil circuit (i.e., a signal that the oil amount in the oil return box is insufficient). This can remind the operator to handle it.

[0006] Preferably, the oil tank body outer wall is provided with a magnetic pump, the oil tank body oil outlet is connected with the magnetic pump inlet through a second oil pipe, the magnetic pump outlet is connected with a three-way connector through a first oil pipe, the three-way connector is also connected with a third oil pipe and a sixth oil pipe, the third oil pipe and the sixth oil pipe are respectively connected with a dynamic pressure spindle oil supply end, and the first cover body is arranged on the top of the rest part of the oil tank body.

[0007] The oil tank body has the advantages that: the structure is simple and reasonable, the oil return box and the oil float are arranged at the oil return pipe, the oil return confirmation mechanism is formed, the oil float can give a feedback signal to the corresponding mechanism when the oil circuit is started, the oil return can be judged in time, and the operator can handle conveniently.
