Description

Technical Field

[0001] The present invention relates to the technical field of lubricating oil filtration, and particularly to a machining lubricating oil filtration system. Background Art

[0002] During the process of machining parts, machine tools generally use lubricating oil. The lubricating oil can reduce the frictional resistance generated during the machining of shaft parts by the machine tool, making the movement of the parts smoother. At the same time, the lubricating oil has the functions of cooling and heat dissipation, reducing surface wear, and extending the service life of the parts. Since the lubricating oil is a liquid, it will also carry away the metal chips generated during machining during its use.

[0003] Through retrieval, it is found that CN221267430U discloses a machining lubricating oil filtration system, which includes a filtration device. The filtration device includes a filtration tank, a multi-stage filter screen for filtration, and a cleaning component for cleaning impurities on the multi-stage filter screen. The multi-stage filter screen is slidably connected in the filtration tank.

[0004] This utility model can sweep the debris into the material collecting hopper through the work of the cleaning plate and the cleaning brush, which has the effect of improving the utilization rate of lubricating oil and reducing costs.

[0016] Beneficial effects The present invention provides a machining lubricating oil filtering system, which has the following beneficial effects: 1. In this machining lubricating oil filtering system, by setting up an oil storage tank, a lower oil pipe, an oil delivery conveyor belt and an oil storage tank, the lubricating oil and metal chips can be divided into multiple portions and conveyed between the iron chip screening mechanism and the filtering box. Subsequently, by using the iron chip screening mechanism, the iron chips in the oil storage tank can be separated, and by using the filter screen assembly, the lubricating oil and steel chips can be separated, so as to separate the steel chips. Compared with the prior art, the present invention realizes the separation of iron chips and steel chips in the metal chips, thus saving costs for the subsequent treatment of the metal chips.

[0017] 2. In this machining lubricating oil filtering system, by setting up a cleaning mechanism and a first spiral brush, the pneumatic telescopic rod can be extended and retracted to drive the connecting plate and the push-pull rod to move back and forth, and then drive the support frame and the second spiral brush to move back and forth.

During the process of filtering the lubricating oil in the present invention, the metal chips do not need to be manually cleaned, which saves time and effort and effectively improves the working efficiency of the entire filtering system.

[0018] 3. In this machining lubricating oil filtering system, by setting up an oil control wheel, a flow hole and a second pulley assembly, the second pulley assembly can drive the oil control wheel to rotate, so that the lubricating oil in the oil storage tank can intermittently flow through the flow hole and into the oil storage tank through the lower oil pipe, thereby effectively avoiding the excessive lubricating oil capacity in the oil storage tank. By controlling the lubricating oil capacity in the oil storage tank, it provides convenience for the magnetic attraction plate to suck out the iron chips in the oil storage tank.

[0019] 4. In this machining lubricating oil filtering system, by setting up a power rod, a cam, a bent tooth plate and a transmission gear, the back-and-forth movement of the connecting plate can drive the back-and-forth movement of the bent tooth plate. By using the meshing transmission between the bent tooth plate and the transmission gear, the power rod and the cam can be driven to rotate. By the rotation of the cam knocking the mesh-shaped discharge hopper, it is not only beneficial to the discharge of the iron chips on the surface of the mesh-shaped discharge hopper, but also beneficial to the small amount of lubricating oil attached to the surface of the iron chips to pass through the mesh-shaped discharge hopper and flow back into the filtering box or the collection box, thus avoiding the waste caused by the outflow of the lubricating oil.
