Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled machine tools, and in particular to a cooling and chip removal device and method for numerically controlled machine tools. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This system logically processes programs defined by control codes or other symbolic instructions, and decodes them, converting the coded digital program instructions into a sequence of signals that move the various parts of the machine tool to achieve predetermined actions, such as the shape, size, and processing of machined parts. During operation, CNC machine tools require cutting fluid to cool the workpiece and tool and flush away debris.

[0003] Publication No. CN113172471A discloses a cooling and chip removal device for a CNC machine tool, which relates to the field of CNC machine tools. In view of the problem that the waste chips generated during the processing of existing machine tools are not cleaned thoroughly enough, a large amount of waste chips remain in the gaps, which easily cause wear on the components inside the machine tool and lead to damage to the lathe, the following solution is proposed, including a machine tool body, a fixture and a CNC milling cutter. The machine tool body is provided with a chip removal mechanism below the processing position of the CNC milling cutter, and a flushing cooling system is installed in the machine tool body. The chip removal mechanism collects the waste chips generated by the CNC milling cutter processing. The flushing cooling system cools the cutting fluid sprayed from the processing position of the CNC milling cutter and flushes and removes the waste chips collected in the chip removal mechanism.

[0004] Although the above-mentioned application and the prior art can filter the cutting fluid for multiple uses, thereby reducing waste liquid discharge, when the above-mentioned application and the prior art use a cleaning plate to filter the debris, the debris in the cutting fluid will accumulate somewhere on the cleaning plate, thereby reducing the effective filtration area of ​​the cleaning plate at that location and decreasing the filtration efficiency. Moreover, when filtering the debris in the cutting fluid, the fine debris will enter the filter holes in the cleaning plate, thereby causing the fine debris to not be cleaned, thereby affecting subsequent normal use. Moreover, when cleaning the debris inside the filter holes, the debris will adhere to the surface of the cleaning plate. If it is not cleaned in time, it will affect subsequent normal use. Therefore, the present invention proposes a cooling and chip removal device and method for CNC machine tools. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a cooling and chip removal device and method for CNC machine tools, which has the advantages of avoiding accumulation, aperture cleaning and preventing adhesion. It solves the problem in the above-mentioned application and the prior art that when a cleaning plate is used to filter debris, the debris in the cutting fluid will accumulate somewhere on the cleaning plate, thereby reducing the effective filtration area of ​​the cleaning plate at that place and lowering the filtration efficiency.

[0009] Furthermore, the hole cleaning assembly also includes a driving cylinder fixedly connected to the inner wall of the machine base and a second filter plate slidably connected to the bottom of the first filter plate. The output end of the driving cylinder is differentially connected to a telescopic column, and one side of the second filter plate is fixedly connected to an end of the telescopic column away from the driving cylinder.

[0010] Furthermore, a plurality of second filter holes and a plurality of third filter holes are fixedly connected to the surface of the second filter plate, a plurality of the second filter holes overlap with the first filter holes, and filter cloths are fixedly connected inside the plurality of the second filter holes.

[0013] Furthermore, a driving motor is fixedly connected to the interior of the fixed box, an output end of the driving motor is fixedly connected to a driving rod, a surface of the driving rod is fixedly connected to a half gear, and the half gear is meshed with the driving gear for transmission.

[0015] The present invention also provides a cooling and chip removal method for a CNC machine tool, which specifically includes the following steps: Step 1: The cutting fluid generated by cutting inside the machine tool box flows into the top of the first filter plate, and the chip flattening component is activated through the control panel to flatten the debris inside the cutting fluid; Step 2: When the chip-leveling assembly moves to one side of the first filter plate, start the scraping assembly and the hole-cleaning assembly through the control panel; Step 3: The chip leveling assembly is then restored to its initial state.

[0016] Compared with the prior art, the present invention provides a cooling and chip removal device and method for a CNC machine tool, which has the following beneficial effects: 1. The cooling and chip removal device and method for a CNC machine tool utilizes a chip leveling assembly. When cutting fluid containing chips falls on the top of the first filter plate, the drive motor is activated through the control panel. The drive motor drives the first screw block to move via the first screw, so that the first screw block drives the screed plate to move on the top of the first filter plate. As the screed plate moves, the chips accumulated on the top of the first filter plate are smoothly pushed to other parts, thereby preventing the chips from always accumulating in a certain place and affecting the filtering effect of the first filter plate, thereby achieving the effect of avoiding accumulation.

[0017] 2. The cooling and chip removal device and method for the CNC machine tool cooperate with the chip leveling component and the hole cleaning component. When the flat plate moves to one side of the first filter plate, the driving cylinder is started through the control panel. The driving cylinder drives the second filter plate to move at the bottom of the first filter plate through the telescopic column, so that the second filter hole is separated from the first filter hole and coincides with the third filter hole. Then, the driving motor controls the first screw to reverse, so that the first screw drives the driven sprocket to rotate through the active sprocket and the chain, and then the second screw drives the moving plate to move through the second screw block. During the movement of the moving plate, the arc block contacts the roller and drives the slide to move in the first filter hole through the extension cylinder. During the movement of the slide, the slide squeezes out the debris inside the first filter hole, so that the interior of the first filter hole no longer adheres to debris, thereby achieving the effect of aperture cleaning.

[0018] 3. The cooling chip removal device and method for the CNC machine tool, through the coordinated use of the scraper assembly and the chip throwing assembly, the electromagnet is de-energized at the same time as the driving cylinder is started, so that the electromagnet and the iron block are separated from each other, and the bottom of the scraper moves to the top of the first filter plate. As the driving motor drives the first screw to reverse, the scraper moves to the top of the collection box, and then the driving motor is started through the control panel. The driving motor drives the half gear to rotate through the driving rod, and the half gear drives the receiving wheel to rotate through the driving gear, so that the receiving wheel drives the extended tube to be stored in the fixed tube through the receiving rope. In this process, the extended tube squeezes the second spring and drives the scraper to rise. When the half gear is no longer in contact with the driving gear, the receiving rope no longer stretches the extended tube, so that the second spring gradually returns to its initial state. When the second spring returns to its initial state, it drives the scraper to move up and down to generate vibration, so that the debris attached to the scraper surface falls into the collection box through the vibration, thereby preventing the debris from always adhering and affecting subsequent use, thereby achieving the effect of preventing adhesion.

The end of the first screw 22 away from the drive motor 21 is rotatably connected to the interior of the machine base 1; When the debris accumulated on the top of the first filter plate 13 needs to be processed, when the cutting fluid containing the debris falls on the top of the first filter plate 13, the drive motor 21 is started through the control panel 121. The drive motor 21 drives the first screw block 221 to move through the first screw rod 22, so that the first screw block 221 drives the screed plate 222 to move on the top of the first filter plate 13. As the screed plate 222 moves, the debris accumulated on the top of the first filter plate 13 is smoothly pushed to other parts, thereby preventing the debris from always accumulating in one place and affecting the filtering effect of the first filter plate 13.

An iron block 321 is fixedly connected to the top of the scraper 32. When it is necessary to process the processed debris on the top of the first filter plate 13, the electromagnet 31 is de-energized through the control panel 121, so that the electromagnet 31 and the iron block 321 are separated from each other, thereby moving the bottom of the scraper 32 to the top of the first filter plate 13. As the driving motor 21 drives the first screw 22 to reverse, the first screw block 221 drives the scraper 32 to move on the top of the first filter plate 13 through the screed plate 222. As the scraper 32 continues to move, the scraper 32 scrapes the debris on the top of the first filter plate 13 into the inside of the collection box 15, thereby preventing the debris from accumulating on the top of the first filter plate 13 and affecting subsequent normal use. For specific example three, please refer to Figures 1 to 11 According to the cooling and chip removal device for a CNC machine tool provided in the second specific embodiment, this embodiment provides a further technical solution: The hole cleaning component 4 includes a driving sprocket 41 fixedly connected to the surface of the first screw 22 and a second screw 42 rotatably connected to the inside of the machine base 1, the surface of the second screw 42 is fixedly connected to a driven sprocket 421, and the driven sprocket 421 and the driving sprocket 41 are transmitted through a chain 411, the surface of the second screw 42 is threadedly connected to a second screw block 422, the surface of the second screw block 422 is fixedly connected to a movable plate 423, and the top of the movable plate 423 is fixedly connected to a plurality of arc blocks 424, the hole cleaning component 4 also includes a driving cylinder 43 fixedly connected to the inner wall of the machine base 1 and a second filter plate 432 slidably connected to the bottom of the first filter plate 13, the output end of the driving cylinder 43 is differentially connected to a telescopic column 431, and the second One side of the filter plate 432 is fixedly connected to the end of the telescopic column 431 away from the driving cylinder 43, and a plurality of second filter holes 433 and a plurality of third filter holes 434 are fixedly connected to the surface of the second filter plate 432. The plurality of second filter holes 433 coincide with the first filter hole 131, and the interiors of the plurality of second filter holes 433 are fixedly connected to filter cloths. The interiors of the plurality of third filter holes 434 are slidably connected to the slide 44, and the interior of the slide 44 is fixedly connected to the first spring 441, and the interior of the slide 44 is slidably connected to the extension tube 442, and the top of the extension tube 442 is fixedly connected to the bottom of the first spring 441, and the bottom of the extension tube 442 is rotatably connected to the roller 443, and the roller 443 is squeezed and fitted with the arc block 424; The filter cloth is fixedly connected to the inner surface of the base 1, and the surfaces of the leveling plate 222 and the movable plate 423 are fixedly connected with guide blocks, which are slidably connected to the surfaces of the guide rods. The inner surfaces of the plurality of second filter holes 433 are fixedly connected with filter cloths. The arrangement of the filter cloths can perform secondary filtration on the treated cutting fluid, so that the debris in the cutting fluid can be secondary purified. When the roller 443 is not in contact with the movable plate 423, the roller 443 is located in the middle of one side of the movable plate 423.

When the movable plate 423 is no longer in contact with the roller 443, the first spring 441 returns to its initial state and vibrates. The vibration is transmitted to the first filter plate 13 through the second filter plate 432, so that the cutting fluid in the debris on the top of the first filter plate 13 can be quickly separated from the cutting fluid, thereby accelerating the filtration efficiency. When the debris inside the first filter hole 131 needs to be processed, when the screed plate 222 moves to one side of the first filter plate 13, the driving cylinder 43 is started through the control panel 121, and the driving cylinder 43 drives the second filter plate 432 to move at the bottom of the first filter plate 13 through the telescopic column 431, so that the second filter hole 433 is separated from the first filter hole 131 and overlaps with the third filter hole 434, and then the first screw 22 is controlled by the driving motor 21 to reverse, so that the first screw 22 The driven sprocket 421 is driven to rotate by the driving sprocket 41 and the chain 411, and the second screw 42 drives the movable plate 423 to move via the second screw block 422. During the movement of the movable plate 423, the arc block 424 contacts the roller 443 and drives the slide 44 to move in the first filter hole 131 via the extension cylinder 442.

As the driving motor 21 drives the first screw 22 to reverse, the scraper 32 moves to the top of the collection box 15, and then the driving motor 52 is started through the control panel 121. The driving motor 52 drives the half gear 522 to rotate through the driving rod 521, and the half gear 522 drives the collecting wheel 511 to rotate through the driving gear 513, so that the collecting wheel 511 can be rotated. The extending tube 532 is driven by the storage rope 512 to be stored inside the fixed tube 53. During this process, the extending tube 532 squeezes the second spring 531 and drives the scraper 32 to rise. When the half gear 522 is no longer in contact with the driving gear 513, the storage rope 512 no longer stretches the extending tube 532, causing the second spring 531 to gradually return to its initial state. When the second spring 531 returns to its initial state, it drives the scraper 32 to move up and down, generating vibration, so that the debris attached to the surface of the scraper 32 falls into the interior of the collection box 15 due to the vibration, thereby preventing the debris from always adhering to the surface and affecting subsequent normal use. Specific embodiment 5, the present invention also provides a cooling and chip removal method for a CNC machine tool, the CNC machine tool cooling and chip removal method specifically comprises the following steps: Step 1: The cutting fluid generated by cutting inside the machine tool box 12 flows into the top of the first filter plate 13, and the chip flattening component 2 is activated through the control panel 121 to flatten the debris inside the cutting fluid; Step 2: When the chip leveling assembly 2 moves to one side of the first filter plate 13, the chip scraping assembly 3 and the hole cleaning assembly 4 are started through the control panel 121; Step 3: The chip leveling assembly 2 is then restored to its initial state.

[0025] Working principle: When the debris accumulated on the top of the first filter plate 13 needs to be processed, when the cutting fluid containing the debris falls on the top of the first filter plate 13, the drive motor 21 is started through the control panel 121, and the drive motor 21 drives the first screw block 221 to move through the first screw rod 22, so that the first screw block 221 drives the screed plate 222 to move on the top of the first filter plate 13. As the screed plate 222 moves, the debris accumulated on the top of the first filter plate 13 is smoothly pushed to other parts, thereby preventing the debris from always accumulating in a certain place and affecting the filtering effect of the first filter plate 13. When the debris inside the first filter hole 131 needs to be processed, when the screed plate 222 moves to one side of the first filter plate 13, the control panel 121 is started. The driving cylinder 43 drives the second filter plate 432 to move at the bottom of the first filter plate 13 through the telescopic column 431, so that the second filter hole 433 is separated from the first filter hole 131 and coincides with the third filter hole 434. Then, the driving motor 21 controls the first screw 22 to reverse, so that the first screw 22 drives the driven sprocket 421 to rotate through the active sprocket 41 and the chain 411, and then the second screw 42 drives the moving plate 423 to move through the second screw block 422. During the movement of the moving plate 423, the arc block 424 contacts the roller 443 and drives the slide 44 to move in the first filter hole 131 through the extension cylinder 442. During the movement of the slide 44, the slide 44 removes the debris inside the first filter hole 131. The first filter plate 13 is squeezed out of the filter 13 so that the interior of the first filter hole 131 is no longer attached to debris. When the processed debris on the top of the first filter plate 13 needs to be processed, the electromagnet 31 is powered off through the control panel 121 to separate the electromagnet 31 and the iron block 321 from each other, thereby moving the bottom of the scraper 32 to the top of the first filter plate 13. As the driving motor 21 drives the first screw 22 to reverse, the first screw block 221 drives the scraper 32 to move on the top of the first filter plate 13 through the leveling plate 222. As the scraper 32 continues to move, the scraper 32 scrapes the debris on the top of the first filter plate 13 into the inside of the collection box 15, thereby preventing the debris from accumulating on the top of the first filter plate 13 and affecting subsequent normal use. When the debris attached to the surface of the scraper 32 needs to be cleaned, the first filter plate 13 is pulled out of the filter 13. The drive motor 52 is started through the control panel 121. The drive motor 52 drives the half gear 522 to rotate through the drive rod 521. The half gear 522 drives the storage wheel 511 to rotate through the driving gear 513, so that the storage wheel 511 drives the extension tube 532 to be stored inside the fixed tube 53 through the storage rope 512. During this process, the extension tube 532 squeezes the second spring 531 and drives the scraper 32 to rise. When the half gear 522 and the driving gear 513 are no longer in contact, the storage rope 512 no longer stretches the extension tube 532, so that the second spring 531 gradually returns to its initial state. When the second spring 531 returns to its initial state, it drives the scraper 32 to move up and down to generate vibration, so that the debris attached to the surface of the scraper 32 falls into the inside of the collection box 15 through the vibration.This prevents debris from always sticking and affecting subsequent normal use.

[0027] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0028] Parallel: The parallel defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, allowing for situations where the two sides are not absolutely parallel due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness. Small angle errors are allowed. For example, within an assembly error range of 10 degrees, it can be understood as a parallel relationship.

[0029] Vertical: The vertical defined in this application is not limited to an absolute vertical intersection relationship (angle of 90 degrees). It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and structural flatness. It allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.
