Description

Technical Field

[0001] The utility model relates to the technical field of oil injectors, in particular to an automatic lubricating oil injection device. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It is generally composed of base oil and additives. Lubricating oil is a technology-intensive product, a mixture of complex hydrocarbons, and mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering.

[0003] During the use of existing automatic oiling equipment, the lubricating oil extracted by the metering pump is transported to the external equipment through a pipeline. After the transportation is completed, some lubricating oil will remain in the pipeline. The residual lubricating oil will merge with the lubricating oil injected next time, thereby increasing the subsequent injection amount of lubricating oil and reducing the accuracy of the oiling equipment.

[0007] Preferably, the oil delivery mechanism comprises a metering pump and an oil delivery pipe, the oil delivery pipe is connected to the metering pump pipe clamp, and the metering pump is connected to the reflux box pipeline.

[0008] Preferably, an oil drain pipe is installed on the side of the reflux box away from the oil delivery mechanism, and a solenoid valve is installed on the oil drain pipe.

[0009] Preferably, a refueling pipe is fixed to the middle of the top end of the top cover, and a sealing cap is connected to the top end of the refueling pipe through threads.

[0010] Preferably, an oil guide seat is installed at the lower part of the machine base, and the oil guide seat is a conical structure.

[0011] Preferably, one end of the oil delivery pipe passes through the machine base and the oil barrel and is fixedly connected to the bottom end of the oil guide base.

[0012] Preferably, an operation panel is installed on one side of the machine base, and the operation panel is electrically connected to the metering pump, the solenoid valve and the reflux pump.

[0013] The beneficial technical effects are:

[0014] By setting up a reflux mechanism, after the lubricating oil is delivered, the reflux pump in the oil delivery mechanism can draw oil into the reflux box through the reflux pipe. At this time, the lubricating oil retained in the delivery pipeline will flow back into the oil barrel through the reflux box, reflux pipe, reflux pump and oil filling pipe, thereby avoiding residual lubricating oil in the pipeline and preventing it from merging with the lubricating oil injected next time, thereby ensuring the subsequent injection amount of lubricating oil and improving the accuracy of the oil filling equipment.

A reflux pipe 502 is connected to the reflux box 501, and the lubricating oil collected in the reflux box 501 moves along the reflux pipe 502 to the reflux pump 503. A reflux pump 503 is installed at one end of the reflux pipe 502, and the reflux pump 503 can extract the residual lubricating oil. An oil filling pipe 504 is installed on one side of the reflux pump 503, and the reflux lubricating oil enters the oil barrel 2 through the oil filling pipe 504, and the reflux pump 503 is fixed on the top cover 3, and one end of the oil filling pipe 504 extends into the oil barrel 2.

[0022] like Figure 1-Figure 3 As shown, the oil delivery mechanism 4 includes a metering pump 401 and an oil delivery pipe 402 . The oil delivery pipe 402 is connected to the metering pump 401 by a pipe clamp, and the metering pump 401 is connected to the reflux box 501 by a pipeline, so that the metering pump 401 can quantitatively extract lubricating oil through the oil delivery pipe 402 .

[0023] like Figure 1-Figure 3 As shown, an oil drain pipe 6 is installed on the side of the reflux box 501 away from the oil delivery mechanism 4, and an electromagnetic valve 7 is installed on the oil drain pipe 6 to facilitate the extraction of lubricating oil through the oil drain pipe 6, and the electromagnetic valve 7 can control the on-off of the oil drain pipe 6.

[0024] like Figure 1-Figure 2 As shown, a refueling pipe 8 is fixed in the middle of the top of the top cover 3, and a sealing cap 9 is threadedly connected to the top of the refueling pipe 8, so that an external refueling device can inject lubricating oil into the oil barrel 2 through the refueling pipe 8, and the sealing cap 9 can seal the top of the refueling pipe 8.

[0025] like Figure 1-Figure 2 As shown, an oil guide seat 10 is installed at the lower part of the machine base 1, and the oil guide seat 10 is a conical structure, which facilitates the guidance of the lubricating oil through the oil guide seat 10.

[0026] like Figure 1-Figure 2 As shown, one end of the oil delivery pipe 402 passes through the machine base 1 and the oil barrel 2 and is fixedly connected to the bottom end of the oil guide seat 10, so that the oil delivery pipe 402 can extract the lubricating oil on the oil guide seat 10.

After the discharge is completed, the solenoid valve 7 is closed. At this time, the reflux pump 503 in the oil delivery mechanism 4 draws the lubricating oil into the reflux box 501 through the reflux pipe 502. At this time, the lubricating oil retained in the delivery pipeline is refluxed to the oil barrel 2 through the reflux box 501, the reflux pipe 502, the reflux pump 503 and the oil filling pipe 504, thereby avoiding residual lubricating oil in the pipeline and preventing it from merging with the lubricating oil injected next time, thereby ensuring the subsequent injection amount of lubricating oil and improving the accuracy of the oil filling equipment.
