Technical Field

[0002] Machine tools are one of the commonly used equipment for metal workpiece processing. During the process of machining workpieces, cutting fluid is needed to cool the workpieces and lubricate the tools, and the cutting fluid also washes away the chips. Traditional machine tools generally use cutting fluid to cool and lubricate the tool, as well as to flush the workpiece to prevent debris from remaining on the surface of the workpiece after cutting. This is especially true for the processing of fine parts. When there is debris on the surface of the part, it will cause increased wear on the part during operation. When processing fine parts, the machine tool generally uses disposable cutting fluid in order to reduce the debris on the part, because the filtered cutting fluid still contains fine debris, and after flushing the parts, debris remains on the surface of the parts. However, the cost of using disposable cutting fluid is high. Not only do the parts need to be flushed during processing, but after processing, the machine tool, fixtures, etc. also need to be flushed to improve the accuracy of the machine tool and fixtures.

[0020] The filtering mechanism includes two guide grooves 11, which are respectively opened in the inner cavity of the machine tool body 1 and located on the side of the processing table 3 close to the support bin 13 and the side away from the support bin 13. The bottom of the guide groove 11 is fixedly connected to the guide pipe 12, and the bottom end of the guide pipe 12 is fixedly connected to the support bin 13. The inner cavity of the support bin 13 is slidably connected with a collection box 14, and the inner cavity of the collection box 14 is fixedly connected with a mounting plate 15. The bottom end of the mounting plate 15 is fixedly connected with a spring 16 and a damping telescopic rod 17. The damping telescopic rod 17 is located at the center of the inner cavity of the spring 16. The bottom end of the damping telescopic rod 17 is fixedly connected with a filter plate 18. The protruding rod 20 contacts the bottom end of the filter plate 18. The bottom end of the support bin 13 is fixedly connected with a shunt pipe 23; A connecting pipe 31 is fixedly connected to one side of the inner cavity of the machine tool body 1 away from the support bin 13, a spray pipe 33 is fixedly connected to the top of the connecting pipe 31, a delivery pump 32 is fixedly connected to the bottom of the connecting pipe 31, a storage bin 30 is fixedly connected to the bottom of the shunt pipe 23, and an input end of the delivery pump 32 is fixedly connected to the storage bin 30; The cross section of the protruding rod 20 is conical, and when the protruding rod 20 contacts the lifting rod 22, the spring 21 is in a downwardly stretched state, and the spring 3 26 is in a free state; The blocking block 27 is fitted with the inner wall of the shunt pipe 23, and the side of the discharge valve 24 away from the shunt pipe 23 is located outside the machine tool body 1; The top end of the mounting plate 15 is inclined toward the center of the filter plate 18 . The top end of the filter plate 18 is fixedly connected with a blocking plate, and the blocking plate is in contact with one side of the mounting plate 15 close to the center of the filter plate 18 .

[0021] In this embodiment, firstly, the external sewage pipe is connected to the discharge valve 24 (kept in a closed state). When the workpiece is processed, the cutting tool device 4 sprays the cutting fluid. At this time, the protruding portion of the protruding rod 20 presses the lifting rod 22, the spring 21 is in a downwardly stretched state, and the spring 3 26 is in a free state, and at this time the pull rope 28 is in a straightened state, and the blocking block 27 is contracted in the inner cavity of the shunt pipe 23 by the tension of the spring 3 26. At this time, the discharge valve 24 is in a closed state, and the cutting fluid carries a small amount of debris on the surface of the workpiece along the guide groove 11 and the guide pipe 12 into the inner cavity of the collection box 14, and the cutting fluid is simply filtered by the filter plate 18; After filtering, the cutting fluid with fine debris enters the inner cavity of the storage bin 30 along the shunt pipe 23 for storage. When the workpiece is processed, the staff takes out the workpiece and starts the motor 19 to drive the protruding rod 20 to flip, so that the protruding part of the protruding rod 20 is separated from the lifting rod 22. At this time, the spring 21 in the downward stretched state contracts and drives the lifting rod 22 to rise through the tension. The lifting rod 22 rises and pulls the pull rope 28 to rise, thereby pulling the blocking block 27 along the axial direction of the blocking telescopic rod 25 to move to the center of the inner cavity of the shunt pipe 23, and the part of the shunt pipe 23 below the discharge valve 24 is blocked. The discharge valve 24 is opened, and then the delivery pump 32 is started to extract the chip liquid after simple filtration in the inner cavity of the storage bin 30 along the connecting pipe 31. After simple filtration by the filter plate 18, the chip liquid with fine chips only washes a large amount of chips on the surface of the movable table 7 and the fixture 8, thereby realizing the secondary utilization of the cutting fluid. The secondary utilized cutting fluid washes a large amount of chips on the surface of the movable table 7 and the fixture 8 down to the inner cavity of the collecting box 14, and then the cutting fluid after secondary utilization enters the inner cavity of the shunt pipe 23. Due to the blocking of the bottom of the shunt pipe 23 by the blocking block 27, the cutting fluid after secondary utilization is discharged from the discharge valve 24 to the outside. Then, the protruding part of the protruding rod 20 is driven by the motor 2 19 to swing back and forth upward, and it is ensured that the protruding rod 20 does not contact the lifting rod 22, and the protruding rod 20 contacts the bottom end of the filter plate 18, so that the protruding part of the protruding rod 20 knocks the filter plate 18, and the knocked filter plate 18 is bounced by the elasticity of the spring 1 16 and the damping telescopic rod 17, thereby shaking off the cutting fluid contaminated on the surface of the debris, and preventing the filter plate 18 from being blocked, so as to facilitate the recycling of the debris in the later stage, and then the staff pulls the collection box 14 out of the inner cavity of the support bin 13 to process the debris in the inner cavity of the collection box 14.

[0022] It should be noted that the main difference between this solution and the prior art is that the traditional precision parts cutting machine uses disposable cutting fluid. Because the repeatedly filtered cutting fluid contains a lot of debris, the precision parts will carry debris after the cutting fluid comes into contact with the precision parts, causing serious wear of the subsequent precision parts during operation. At the same time, after the cutting is completed, the fixture 8, the cutter head and the machine tool surface need to be rinsed with cutting fluid, which is very wasteful of cutting fluid. This solution uses disposable cutting fluid when processing precision parts, and uses filtered and circulated cutting fluid when rinsing the fixture 8, the cutter head and the machine tool surface, which can effectively reduce the use of cutting fluid.

[0023] Working principle and use process: first connect the external sewage pipe to the discharge valve 24, then the protruding part of the protruding rod 20 presses the lifting rod 22, the tension of the spring 3 26 drives the blocking block 27 to contract, the inner cavity of the support bin 13 is connected with the storage bin 30 through the shunt pipe 23, and the discharge valve 24 is closed; Then, the workpiece is placed in the inner cavity of the fixture 8, and then the switch door 2 is closed. The cutter device 4 is controlled by using the control panel of the machine tool body 1, and the workpiece is processed by the cutter device 4. During the processing, the cutter device 4 sprays cutting fluid on the workpiece, and the motor 5 is started to drive the screw rod 6 to rotate, and the movable table 7 engaged with it is driven to move along the axis direction of the screw rod 6 and the guide rod 9, thereby driving the fixture 8 at the top of the movable table 7 to move, and then driving the workpiece to move to cooperate with the cutter device 4 for processing; Then the cutting fluid with the debris falls on the surface of the moving table 7 and the fixture 8, and the debris may remain on the surface of the moving table 7 and the fixture 8. At this time, the telescopic protective cover 10 is used to prevent the cutting fluid and the debris from falling into the inner cavity of the processing table 3, affecting the normal use of the screw 6 and the guide rod 9. Then the cutting fluid with some debris flows along the telescopic protective cover 10 or directly from the moving table 7 to the inner cavity of the guide groove 11, and then along the guide groove 11 and the guide pipe 12 into the inner cavity of the collection box 14. At this time, the cutting fluid is filtered by the filter plate 18. Due to the penetration of the shunt pipe 23, the filtered cutting fluid enters the inner cavity of the storage bin 30 along the shunt pipe 23 for storage; When the workpiece is processed, the workpiece is taken out, and then the motor 2 19 is started to drive the protruding rod 20 to swing, so that the protruding part of the protruding rod 20 is separated from the lifting rod 22, and the lifting rod 22 is driven to move upward by the pulling force of the spring 21, and the blocking block 27 is driven to move to block the lower part of the discharge valve 24 by the tension of the spring 3 26, so that the cutting fluid cannot enter the inner cavity of the storage bin 30, and the discharge valve 24 is in an open state at this time; Then, the delivery pump 32 is started to extract the cutting fluid from the inner cavity of the storage bin 30, and sprays it from the spray pipe 33 along the connecting pipe 31 to the surface of the movable platform 7 and the fixture 8, and the cutting fluid after simple filtration is used to clean the debris on the surface of the movable platform 7 and the fixture 8. At this time, the cutting fluid with a large amount of debris enters the inner cavity of the collection box 14 along the guide groove 11, and the cutting fluid passes through the collection box 14 and is discharged from the discharge valve 24; After the waste liquid is discharged, the motor 2 19 drives the protruding rod 20 to swing, and the protruding part of the protruding rod 20 only faces upward. The protruding rod 20 knocks the filter plate 18 while swinging, and the elasticity of the spring 16 drives the filter plate 18 to vibrate, thereby shaking off the cutting liquid on the surface of the debris, and preventing the filter plate 18 from being blocked, and then the filter plate 18 can be cleaned.
