Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a CNC lathe equipped with a cutting fluid filtration structure. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other operations. In CNC lathe machining, the role of cutting fluid is crucial. Cutting fluid has excellent cooling, lubrication, rust prevention, oil removal and cleaning functions, corrosion prevention functions, and is easy to dilute.

[0003] The "Cutting Fluid Filtration Device" disclosed in application number "202323515629.3" includes a filter box, a support frame for support is provided at the bottom of the filter box, a conduit for conveying liquid is provided at the top of the support frame, a disassembly port is provided on the left side wall of the filter box, a sealing baffle is movably installed on the outside of the disassembly port, and a separate access port is provided on the inner wall of the disassembly port. In this invention, by changing the installation method of the disassembly plate, the cutting fluid passes through the disassembly filter screen for filtration during cutting fluid filtration. Compared with the existing method of installing the disassembly plate inside the filter box, this device changes the installation method of the disassembly plate to a removable installation method. When cleaning is required, the disassembly plate can be simply pulled out to replace the disassembly filter screen, which is very convenient.

[0004] However, the above method still has the following drawbacks: the cutting fluid can be filtered through the filter screen, but the entire disassembly plate needs to be locked with two locking bolts, which is inconvenient to operate, consumes more manpower and time, and can easily cause waste chips to fall off the filter screen. In addition, the filtration capacity of the CNC lathe for the cutting fluid cannot be guaranteed during the process of removing the filter screen, which can easily cause waste chips to enter the cutting fluid tank. Utility Model Content

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The spindle supports the support frame and side plates. The support frame supports the filter screen. By placing the outlet of the cutting fluid return pipe on the same vertical plane as the spindle, two adjacent filter screens on the spindle can collect and store waste chips after filtering the cutting fluid, preventing the waste chips from falling off. The spindle is driven by the drive assembly, causing the filter screen carrying the waste chips to tilt downwards, which can clean the waste chips. The operation is simple and convenient, and there is no need to remove it from the water tank, saving manpower and time.

[0016] 2. After the filter screen is adjusted, the drive component one can achieve self-locking of the spindle to maintain its firmness. During the cleaning of waste chips, several filter screens on the spindle surface can work alternately to ensure the continuous filtration capacity of the cutting fluid. The drive component two can control the automatic opening and closing of the protective cover. Attached Figure Description
