Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool lubrication technology, specifically to a CNC machine tool lubrication and cooling device. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. It is made of a variety of high-performance additives through scientific compounding and has good cooling performance, lubrication performance, rust prevention performance, degreasing and cleaning function, anti-corrosion function, and easy dilution characteristics.

[0003] As disclosed in CN215748138U, a cutting fluid circulation device for CNC machine tools includes a CNC machine tool body. A CNC device is installed inside the machine tool body. A filter box is provided on the bottom surface of the machine tool body. Connecting pipes are connected to both ends of the bottom surface of the machine tool body. The other ends of the two connecting pipes pass through the filter box and are connected to filter cylinders. A recovery tank is fixedly installed on the bottom surface of the filter box. With the above technical solution, the beneficial effects of this utility model are: the two filter cylinders can filter debris from the cutting fluid, and then the filtered cutting fluid is discharged into the recovery tank through a drain pipe for storage, facilitating reuse.

[0004] Although the aforementioned patent features two filter cartridges for filtration, the angled filter cartridges require disassembly of the pipes or adjustment of the angle to remove them, which limits the operating space. Especially on production lines with high-density CNC machine tool layouts, the replacement process may require downtime of more than 30 minutes, seriously affecting production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A CNC machine tool lubrication and cooling device includes a cooling box 1. A turntable 2 is movably installed on the upper part of the cooling box 1. Six filter mechanisms are provided on the turntable 2. Each filter mechanism includes a limiting groove 4. Six limiting grooves 4 are opened with equal arcs in the circumference of the turntable 2. A limiting plate 5 is movably installed at the upper end of the limiting groove 4. A filter cylinder 6 is fixedly connected to the bottom end of the limiting plate 5. A motor 7 is fixedly installed at the top middle part of the cooling box 1. The output shaft of the motor 7 passes through the cooling box 1 and is fixedly connected to the top middle part of the turntable 2. An inlet pipe 8 is fixedly installed at the upper right side of the cooling box 1. An outlet pipe 9 is connected to the outside of the bottom right side of the cooling box 1. A spiral cold water pipe 15 is fixedly installed at the lower part of the interior of the cooling box 1.

[0027] In this embodiment, a multi-station rapid switching system is configured. The turntable 2 is driven by the motor 7 to realize the instantaneous switching of the standby filter cartridge 6. After the old and new filter cartridges 6 are switched, the coolant can continue to be filtered. The switching speed is fast. When one filter cartridge 6 is taken out, the other filter cartridge 6 is put into use immediately.

[0028] like Figure 2 and Figure 3 As shown, an electric push rod 3 is fixedly installed on the lower left side of the cooling box 1. The output shaft of the electric push rod 3 passes through the cooling box 1 and is provided with an ejection mechanism. The ejection mechanism includes a cone head 10. The cone head 10 is fixedly installed at the output shaft end of the electric push rod 3. A positioning rod 11 is fixedly connected to the top of the cone head 10. A positioning sleeve 12 matching the positioning rod 11 is fixedly installed at the middle of the bottom end of the filter cartridge 6. A take-out tube 13 is fixedly installed at the upper left side of the cooling box 1. A tube cap 14 is detachably installed at the top of the take-out tube 13.

[0029] In this embodiment, a modular quick-change structure is adopted. The filter cartridge 6 is vertically and directionally ejected and replaced by a rotary multi-station design and an electric push rod lifting mechanism, which completely avoids pipeline disassembly and angle adjustment operations, reduces the operating space requirement and the replacement time.

[0030] Working principle: During operation, the coolant enters the cooling tank 1 through the inlet pipe 8 and flows through the filter cartridge 6, which is currently in the working position. Impurities are trapped inside the filter cartridge 6, while the clean coolant flows through the filter cartridge 6 and into the bottom of the cooling tank 1. After being cooled by the spiral cold water pipe 15, it is transported back to the machine tool lubrication system through the discharge pipe 9. During replacement, motor 7 starts, driving turntable 2 to rotate 60°, aligning the next filter cartridge 6 with the working position. At this time, the positioning sleeve 12 of filter cartridge 6 has not yet docked with the positioning rod 11, and it is only stable by the cooperation of the limiting plate 5 and the limiting groove 4. When it is necessary to remove filter cartridge 6, electric push rod 3 is activated, pushing the cone head 10 upward, so that the positioning rod 11 is accurately inserted into the positioning sleeve 12 at the bottom of filter cartridge 6. As electric push rod 3 continues to extend, positioning rod 11 lifts filter cartridge 6 upward, causing it to disengage from the limiting groove 4. The operator only needs to open the pipe cover 14 to remove the old filter cartridge 6. The whole process only takes 2 to 3 minutes, without stopping the machine or disassembling the pipeline. At the same time, another filter cartridge 6 is in place and begins filtration. The cooling system continues to run, ensuring that the machine tool lubrication is not interrupted.
