Description

Technical Field

[0001] This invention relates to the field of boring technology, specifically a boring device with chip collection to prevent scratches on the machined surface. Background Technology

[0002] During the boring process, the boring bar generates a large amount of chips as it cuts the workpiece. Due to the high temperature and pressure environment of the cutting process, some of these chips easily adhere to the surface of the boring bar. Conventional boring bar designs have limited ability to remove these chips. When the adhered chips accumulate to a certain extent, they will embed themselves into the machined surface during subsequent cutting, causing defects such as scratches and pits on the machined surface, severely reducing the surface roughness and dimensional accuracy of the machined surface.

[0003] Currently, due to the irregular shapes of the chips generated during processing—including long strips, blocks, and fine particles—various types of chips easily accumulate on the filter screen during filtration, leading to filter clogging. Once the filter screen is clogged, the flow rate and pressure of the working medium will fluctuate, affecting the cooling and lubrication effect of the cutting fluid on the boring tool, thereby accelerating tool wear and reducing machining accuracy. Simultaneously, filter clogging can also cause excessive internal pressure in the equipment, leading to seal damage, pipe ruptures, and other malfunctions, severely impacting the normal operation and service life of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a boring machine with chip collection and anti-scratching function to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The boring machine with chip collection and anti-scratching function includes a worktable, a collection unit, an anti-clogging unit, a fixing unit, and a drive unit. The worktable is placed on a horizontal ground. The collection unit is fixedly installed on the worktable. The anti-clogging unit is fixedly connected to the collection unit and has the function of preventing clogging. The fixing unit is fixedly connected to the worktable. The drive unit is fixedly connected to the worktable and the collection unit.

[0007] The worktable is used to install and fix the collection unit, anti-clogging unit, fixing unit, and drive unit. The collection unit is used to collect debris, the anti-clogging unit is used to prevent clogging during the collection process, the fixing unit is used to install and fix the workpiece, and the drive unit is used to provide power. After the fixing unit installs and fixes the workpiece, the drive unit is started to bore the workpiece. At the same time, the collection unit collects debris of different sizes in stages, and the anti-clogging unit prevents large debris from adhering to the filter screen, which would reduce the debris collection efficiency and cause debris to remain and damage the machining surface during processing.

[0008] Furthermore, the collection unit includes a fixed box, fan blades, a fixed plate, a screw, and a conductive slip ring. The fixed box is fixedly installed on the upper surface of the workbench, the fixed end of the fan blade is fixedly installed at the end of the fixed box, the fixed plate is fixedly installed on the inner surface of the fixed box, the screw consists of a helical section and a smooth section, one end of the smooth section of the screw is fixedly installed on the fixed plate, conductive sheets are evenly distributed on the surface of the smooth section of the screw, and a conductive slip ring is fitted on the smooth section of the screw. The fixed box is fixedly connected to the anti-blocking unit.

[0009] Furthermore, the collection unit also includes a connecting rod, a spring cylinder, a pressure plate, a follower disk, a filter screen, an oil outlet pipe, and a push rod. One end of the connecting rod is fixedly connected to a conductive slip ring, and the other end of the connecting rod abuts against the pressure plate. The connecting rod is connected to a fixed plate via a return spring. One end of the spring cylinder is fixedly connected to the pressure plate, and the other end of the spring cylinder is rotatably connected to the fixed plate. The follower disk is fixedly mounted on the pressure plate and threadedly connected to the helical section of the screw. The filter screen is fixedly installed inside a fixed box. One end of the oil outlet pipe passes through the fixed plate and extends into the spring cylinder, while the other end is connected to the drive unit. One end of the push rod is fixedly mounted on the filter screen at the end away from the fan blades. The spring cylinder is filled with cooling lubricating oil.

[0010] During the boring operation, the controller controls the fan blades to rotate, thereby generating negative pressure. This causes the chips generated at the machining point to enter the fixed box and be collected by a filter screen. When the active disk rotates and moves closer to the follower disk, it drives the follower disk to rotate, which in turn drives the pressure plate and spring cylinder to rotate synchronously. At this time, the follower disk and pressure plate rotate along the spiral section of the screw and move to the right. On the one hand, this forces out the cooling lubricating oil inside the spring cylinder, which is then transported through the oil outlet pipe to the inside of the boring bar and boring tool, and finally flows out from inside the boring tool, cooling the boring tool. This prevents the boring tool and chips from sticking together under the high temperature generated during operation, thus avoiding damage to the machined surface caused by continued boring. On the other hand, under the transmission action of the connecting rod, the conductive slip ring is pushed to continue moving to the right along the polished section of the screw, making intermittent contact with the conductive plate of the polished section.

[0011] Furthermore, the anti-clogging unit includes a fixed block, a telescopic spring, a spring-driven electric telescopic rod, a straight rod, a circular ring, and an arc-shaped tube. The fixed block is fixedly installed on the inner wall of the fixed box. One end of the telescopic spring is fixedly connected to the fixed block, and the other end is fixedly connected to the filter screen. The fixed end of the spring-driven electric telescopic rod is fixedly installed on the inner wall of the fixed box, and the output end of the spring-driven electric telescopic rod abuts against the filter screen. The conductive plate on the screw is electrically connected to the spring-driven electric telescopic rod. One end of the straight rod is fixedly connected to the filter screen, and the other end is fixedly connected to the circular ring. There are two arc-shaped tubes, and the arc-shaped tubes are slidably connected to the circular ring.

[0012] Furthermore, the anti-clogging unit also includes a tension spring, a telescopic scraper, a gravity block, a pull rope, a spring push plate, a collection box, and a magnetic block. The two arc-shaped tubes are connected by a tension spring. The telescopic scraper is fixedly connected to the arc-shaped tube. The gravity block is fixedly installed below the telescopic scraper. One end of the pull rope passes through the filter screen and is fixedly connected to the magnetic block located above it. The other end is fixedly connected to the telescopic scraper. One end of the spring push plate is fixedly connected to the fixed box. The other end of the push rod abuts against the spring push plate. A magnet with the same polarity as the magnetic block is provided at the end of the filter screen near the magnetic block. The collection box is fixedly installed on the fixed box. The magnetic block is slidably installed inside the fixed box.

[0013] When the conductive slip ring contacts the conductive plate, the controller's current is transmitted to the conductive slip ring through the conductive plate, ultimately supplying the current to the electric telescopic rod. This controls the extension of the electric telescopic rod, pushing the filter screen to the right and causing the telescopic spring to contract. Simultaneously, the magnet on the green plate pushes the magnetic block to the right, causing the pull rope to move synchronously. The pull rope then pulls the telescopic scraper, causing the arc-shaped tube to compress and stretch the spring upwards along the ring, scraping away large debris such as strips adhering to the filter screen surface. When the conductive slip ring is not in contact with the conductive plate, the spring... When the electric telescopic rod resets, the filter screen moves to the left under the restoring force of the telescopic spring. At this time, the magnetic force between the magnet and the magnetic block on the filter screen decreases. Under the gravity of the weight block, the pull rope moves downward, thereby driving the telescopic scraper and the arc tube to move downward along the ring, scraping the debris on the filter screen downward. On the other hand, the filter screen drives the push rod to push the spring push plate to move to the left, opening the channel of the collection box, allowing the falling debris to enter the collection box, completing the collection of larger strip-shaped debris, while smaller debris enters the external collector through the filter screen.

[0014] Furthermore, the fixing unit includes a slide groove, a hydraulic push rod, a moving block, a bent rod, a double-headed electric push rod, a clamping plate, and a workpiece. The slide groove is fixedly installed on the worktable. The fixed end of the hydraulic push rod is fixedly installed on the slide groove. The output end of the hydraulic push rod is fixedly connected to the moving block. The moving block is slidably installed in the slide groove. One end of the bent rod is fixedly connected to the moving block, and the other end is fixedly connected to the fixed end of the double-headed electric push rod. The telescopic end of the double-headed electric push rod is fixedly connected to the clamping plate. The workpiece is located between the two clamping plates.

[0015] After the worker places the workpiece between the two clamping plates, the controller controls the double-headed electric push rod to adjust the distance, driving the clamping plates to move left and right until the workpiece is stably clamped. After clamping one processing area is completed, the controller controls the hydraulic push rod to start, driving the moving block to move in the slide groove, thereby driving the double-headed electric push rod to move back and forth, thus moving the workpiece to the next processing area, allowing the boring tool to continue processing the workpiece in this processing area.

[0016] Furthermore, the drive unit includes a drive motor, a fixed disk, an electric telescopic clamping disk, a boring bar, a boring tool, and an active disk. The fixed end of the drive motor is fixedly mounted on the side surface of the worktable, and the output end of the drive motor is fixedly connected to the electric telescopic clamping disk. The electric telescopic clamping disk and the fixed disk are connected through a pipe. The fixed disk is fixedly mounted on the side surface of the worktable. The electric telescopic clamping disk is fixedly connected to the boring bar, and the boring bar is fixedly connected to the boring tool. The boring bar and the boring tool are provided with oil outlet channels inside, and the boring bar and the boring tool are connected through a pipe. The boring bar is fixedly connected to the active disk, and the oil outlet pipe is conductively connected to the fixed disk.

[0017] After the workpiece is placed, the boring bar is installed on the electric telescopic clamping plate. The controller controls the drive motor to rotate, which in turn drives the electric telescopic clamping plate to rotate. This causes the boring tool on the boring bar to perform boring operations on the workpiece while simultaneously driving the active disk to rotate, causing the driven disk to rotate synchronously.

[0018] Furthermore, the active disk and the follower disk are alternately provided with magnets of opposite polarities on one end face of each other, and the two magnets of the active disk and the follower disk located on the same axis have opposite polarities.

[0019] To enable the active disk to drive the driven disk to rotate during the rotation process, thereby achieving non-contact transmission, and to facilitate maintenance in case of device failure, thus improving the convenience of maintenance.

[0020] Furthermore, the pitch of the screw helical section gradually increases, with the pitch being the highest at the end of the screw helical section closest to the fan blade.

[0021] The increase in pitch reduces the rotational speed of the pressure plate and the follower disk. In order to make the follower disk drive the pressure plate to squeeze out the cooling lubricating oil inside the spring cylinder when the boring bar gradually moves to the right, in order to avoid excessive pressure inside the spring cylinder due to uniform movement, which could damage the device.

[0022] Furthermore, a controller is provided on the workbench.

[0023] To facilitate staff control of the device's start and stop, and to achieve automation and timely response.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention generates negative pressure by controlling the fan blades to rotate during boring operations. This causes the chips generated at the machining point to enter a fixed box and be collected by a filter screen. When the active disk rotates and moves closer to the follower disk, it drives the follower disk to rotate, thereby causing the pressure plate and spring cylinder to rotate synchronously. At this time, the follower disk and pressure plate rotate along the spiral section of the screw and move to the right. On the one hand, this forces the cooling lubricating oil inside the spring cylinder to be squeezed out and transported through the oil outlet pipe to the inside of the boring bar and boring tool. Finally, it flows out from inside the boring tool, cooling the boring tool and preventing the boring tool and chips from sticking together under high temperature conditions during operation. This avoids damage to the machined surface caused by continued boring and machining. On the other hand, under the transmission action of the connecting rod, the conductive slip ring is pushed to move to the right along the smooth section of the screw, making intermittent contact with the conductive plate of the smooth section.

[0026] 2. In this invention, when the conductive slip ring contacts the conductive sheet, the controller's current is transmitted to the conductive slip ring through the conductive sheet, ultimately supplying the current to the electric telescopic rod. This controls the extension of the electric telescopic rod, pushing the filter screen to the right and causing the telescopic spring to contract. Simultaneously, the magnet on the green plate pushes the magnetic block to the right, causing the pull rope to move synchronously. At this time, the pull rope pulls the telescopic scraper, causing the arc-shaped tube to compress the stretching spring upwards along the ring, scraping away large debris such as strips adhering to the filter screen surface. When the conductive slip ring and the conductive sheet are not in contact... At this point, the spring-loaded electric telescopic rod resets, and the filter screen moves to the left under the restoring force of the telescopic spring. The magnetic force between the magnet and the magnetic block on the filter screen decreases, and under the gravity of the weight block, the pull rope moves downward, thereby driving the telescopic scraper and the arc-shaped tube to move downward along the ring, scraping the debris off the filter screen. On the other hand, the filter screen drives the push rod to push the spring push plate to the left, opening the channel of the collection box, allowing the falling debris to enter the collection box, completing the collection of larger strip-shaped debris, while smaller debris enters the external collector through the filter screen.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example: Figures 1-9 As shown, the present invention provides a technical solution:

[0039] like Figure 1 , Figure 4 As shown, a boring machine with chip collection and anti-scratching function for the machined surface includes a worktable 1, a collection unit 2, an anti-blocking unit 3, a fixing unit 4, and a drive unit 5. The worktable 1 is placed on a horizontal ground. The collection unit 2 is fixedly installed on the worktable 1. The anti-blocking unit 3 is fixedly connected to the collection unit 2 and has the function of preventing blockage. The fixing unit 4 is fixedly connected to the worktable 1. The drive unit 5 is fixedly connected to the worktable 1 and the collection unit 2.

[0040] The workbench 1 is used to install and fix the collection unit 2, the anti-clogging unit 3, the fixing unit 4, and the drive unit 5. The collection unit 2 is used to collect debris, the anti-clogging unit 3 is used to prevent clogging during the collection process, the fixing unit 4 is used to install and fix the workpiece 47, and the drive unit 5 is used to provide power. After the workpiece 47 is installed and fixed by the fixing unit 4, the drive unit 5 is started to bore the workpiece 47. At the same time, the collection unit 2 collects debris of different sizes in stages, and the anti-clogging unit 3 prevents large debris from adhering to the filter screen 210, which would reduce the debris collection efficiency and cause debris to remain and damage the processing surface during processing.

[0041] like Figure 8 , Figure 9 As shown, the collection unit 2 includes a fixed box 21, a fan blade 22, a fixed plate 23, a screw 24, and a conductive slip ring 25. The fixed box 21 is fixedly installed on the upper surface of the workbench 1. The fixed end of the fan blade 22 is fixedly installed at the end of the fixed box 21. The fixed plate 23 is fixedly installed on the inner surface of the fixed box 21. The screw 24 consists of a spiral section and a smooth section. One end of the smooth section of the screw 24 is fixedly installed on the fixed plate 23. Conductive sheets are evenly distributed on the surface of the smooth section of the screw 24. The smooth section of the screw 24 is fitted with a conductive slip ring 25. The fixed box 21 is fixedly connected to the anti-blocking unit 3.

[0042] like Figures 5-9As shown, the collection unit 2 also includes a connecting rod 26, a spring cylinder 27, a pressure plate 28, a follower disk 29, a filter screen 210, an oil outlet pipe 211, and a push rod 212. One end of the connecting rod 26 is fixedly connected to the conductive slip ring 25, and the other end of the connecting rod 26 abuts against the pressure plate 28. The connecting rod 26 is connected to the fixed plate 23 through a return spring. One end of the spring cylinder 27 is fixedly connected to the pressure plate 28, and the other end of the spring cylinder 27 is rotatably connected to the fixed plate 23. The follower disk 29 is fixedly installed on the pressure plate 28 and is threadedly connected to the helical section of the screw 24. The filter screen 210 is fixedly installed inside the fixed box 21. One end of the oil outlet pipe 211 passes through the fixed plate 23 and extends into the spring cylinder 27, and the other end is connected to the drive unit 5. One end of the push rod 212 is fixedly installed on the filter screen 210 at the end away from the fan blade 22. The inside of the spring cylinder 27 is filled with cooling lubricating oil.

[0043] During the boring operation, the controller controls the fan blades 22 to rotate, thereby generating negative pressure. This causes the chips generated at the machining point to enter the fixed box 21 and be collected by the filter screen 210. When the active disk 56 rotates and moves closer to the follower disk 29, it drives the follower disk 29 to rotate, thereby causing the pressure plate 28 and the spring cylinder 27 to rotate synchronously. At this time, the follower disk 29 and the pressure plate 28 rotate along the spiral section of the screw 24 and move to the right, which cools the inside of the spring cylinder 27. The lubricating oil is extruded and transported through the oil outlet pipe 211 to the interior of the boring bar 54 and the boring tool 55. Finally, it flows out from the interior of the boring tool 55 to cool it down, thereby preventing the boring tool 55 from sticking to the chips under the high temperature generated during operation. This avoids damage to the machined surface caused by continuing boring and machining at this time. On the other hand, under the transmission action of the connecting rod 26, the conductive slip ring 25 is pushed to continue to move to the right along the smooth section of the screw 24, making intermittent contact with the conductive sheet of the smooth section.

[0044] like Figure 5 , Figure 6 , Figure 8 As shown, the anti-clogging unit 3 includes a fixed block 31, a telescopic spring 32, a spring-driven electric telescopic rod 33, a straight rod 34, a circular ring 35, and an arc-shaped tube 36. The fixed block 31 is fixedly installed on the inner wall of the fixed box 21. One end of the telescopic spring 32 is fixedly connected to the fixed block 31, and the other end is fixedly connected to the filter screen 210. The fixed end of the spring-driven electric telescopic rod 33 is fixedly installed on the inner wall of the fixed box 21, and the output end of the spring-driven electric telescopic rod 33 abuts against the filter screen 210. The conductive sheet on the screw 24 is electrically connected to the spring-driven electric telescopic rod 33. One end of the straight rod 34 is fixedly connected to the filter screen 210, and the other end is fixedly connected to the circular ring 35. There are two arc-shaped tubes 36, and the arc-shaped tubes 36 are slidably connected to the circular ring 35.

[0045] like Figure 5 , Figure 6 , Figure 8As shown, the anti-clogging unit 3 also includes a tension spring 37, a telescopic scraper 38, a gravity block 39, a pull rope 310, a spring push plate 311, a collection box 312, and a magnetic block 313. The two arc-shaped tubes 36 are connected by the tension spring 37. The telescopic scraper 38 is fixedly connected to the arc-shaped tube 36. The gravity block 39 is fixedly installed below the telescopic scraper 38. One end of the pull rope 310 passes through the filter screen 210 and the fixed block 31 located above it, and is fixedly connected to the magnetic block 313. The other end is fixedly connected to the telescopic scraper 38. One end of the spring push plate 311 is fixedly connected to the fixed box 21. The other end of the push rod 212 abuts against the spring push plate 311. The filter screen 210 is provided with a magnet of the same polarity as the magnetic block 313 at the end near the magnetic block 313. The collection box 312 is fixedly installed on the fixed box 21. The magnetic block 313 is slidably installed inside the fixed box 21.

[0046] When the conductive slip ring 25 contacts the conductive sheet, the controller's current is transmitted to the conductive slip ring 25 through the conductive sheet, and then ultimately to the electric telescopic rod, controlling the spring-loaded electric telescopic rod 33 to extend. This pushes the filter screen 210 to the right, compressing the telescopic spring 32. Simultaneously, the magnet on the green plate pushes the magnetic block 313 to the right, causing the pull rope 310 to move synchronously. At this time, the pull rope 310 pulls the telescopic scraper 38, causing the arc-shaped tube 36 to compress the tension spring 37 and move it upwards along the ring 35, scraping away large debris such as strips adhering to the surface of the filter screen 210. When the conductive slip ring 25 is not in contact with the conductive sheet, the spring-loaded electric telescopic rod 33... 3. Reset: The filter screen 210 moves to the left under the restoring force of the telescopic spring 32. At this time, the magnetic force between the magnet on the filter screen 210 and the magnetic block 313 decreases. Under the gravity of the gravity block 39, the pull rope 310 moves downward, thereby driving the telescopic scraper 38 and the arc tube 36 to move downward along the ring 35, scraping the debris on the filter screen 210 downward. On the other hand, the filter screen 210 drives the push rod 212 to push the spring push plate 311 to the left to open the channel of the collection box 312, allowing the falling debris to enter the collection box 312, completing the collection of larger strip-shaped debris, while smaller debris enters the external collector through the filter screen 210.

[0047] like Figure 3 As shown, the fixed unit 4 includes a slide groove 41, a hydraulic push rod 42, a moving block 43, a bent rod 44, a double-headed electric push rod 45, a clamping plate 46, and a workpiece 47. The slide groove 41 is fixedly installed on the worktable 1. The fixed end of the hydraulic push rod 42 is fixedly installed on the slide groove 41. The output end of the hydraulic push rod 42 is fixedly connected to the moving block 43. The moving block 43 is slidably installed in the slide groove 41. One end of the bent rod 44 is fixedly connected to the moving block 43, and the other end is fixedly connected to the fixed end of the double-headed electric push rod 45. The telescopic end of the double-headed electric push rod 45 is fixedly connected to the clamping plate 46. The workpiece 47 is located between the two clamping plates 46.

[0048] After the worker places the workpiece 47 between the two clamping plates 46, the controller controls the double-headed electric push rod 45 to adjust the distance, driving the clamping plates 46 to move left and right until the workpiece 47 is stably clamped. When the clamping of one processing area is completed, the controller controls the hydraulic push rod 42 to start, driving the moving block 43 to move in the slide groove 41, thereby driving the double-headed electric push rod 45 to move back and forth, so that the workpiece 47 is moved to the next processing area, and the boring tool 55 continues to process the workpiece 47 in this processing area.

[0049] like Figures 1-3 As shown, the drive unit 5 includes a drive motor 51, a fixed plate 52, an electric telescopic clamping plate 53, a boring bar 54, a boring tool 55, and an active disk 56. The fixed end of the drive motor 51 is fixedly installed on the side surface of the worktable 1. The output end of the drive motor 51 is fixedly connected to the electric telescopic clamping plate 53. The electric telescopic clamping plate 53 is connected to the fixed plate 52 through a pipe. The fixed plate 52 is fixedly installed on the side surface of the worktable 1. The electric telescopic clamping plate 53 is fixedly connected to the boring bar 54. The boring bar 54 is fixedly connected to the boring tool 55. The boring bar 54 and the boring tool 55 are provided with oil outlet channels inside. The boring bar 54 and the boring tool 55 are connected inside through a pipe. The boring bar 54 is fixedly connected to the active disk 56. The oil outlet pipe 211 is conductively connected to the fixed plate 52.

[0050] After the workpiece 47 is placed, the boring bar 54 is installed on the electric telescopic clamping plate 53. The controller controls the drive motor 51 to rotate, thereby driving the electric telescopic clamping plate 53 to rotate. This causes the boring tool 55 on the boring bar 54 to perform boring operation on the workpiece 47, while simultaneously driving the active disk 56 to rotate, causing the driven disk to rotate synchronously.

[0051] like Figure 3 , Figure 7 As shown, the active disk 56 and the follower disk 29 are alternately provided with magnets of opposite polarities close to each other on one end face, and the two magnets of the active disk 56 and the follower disk 29 located on the same axis have opposite polarities.

[0052] In order to enable the active disk 56 to drive the driven disk to rotate during the rotation process, thereby realizing non-contact transmission, and at the same time to facilitate maintenance in case of device failure, thereby improving the convenience of maintenance.

[0053] like Figure 9 As shown, the pitch of the helical section of screw 24 gradually increases, with the pitch being the highest at the end of the helical section of screw 24 closest to the fan blade 22.

[0054] The increase in pitch reduces the rotational speed of the pressure plate 28 and the follower disk 29. In order to make the follower disk 29 drive the pressure plate 28 to squeeze the cooling lubricating oil inside the spring cylinder 27 when the boring bar 54 gradually moves to the right, in order to avoid excessive pressure inside the spring cylinder 27 due to uniform movement, which could damage the device.

[0055] like Figure 1 As shown, a controller is installed on workbench 1.

[0056] To facilitate staff control of the device's start and stop, and to achieve automation and timely response.

[0057] Working principle of the invention:

[0058] After the worker places the workpiece 47 between the two clamping plates 46, the controller controls the double-headed electric push rod 45 to adjust the distance, driving the clamping plates 46 to move left and right until the workpiece 47 is stably clamped. When the clamping of one processing area is completed, the controller controls the hydraulic push rod 42 to start, driving the moving block 43 to move in the slide groove 41, thereby driving the double-headed electric push rod 45 to move back and forth, so that the workpiece 47 is moved to the next processing area, and the boring tool 55 continues to process the workpiece 47 in this processing area.

[0059] After the workpiece 47 is placed, the boring bar 54 is installed on the electric telescopic clamping plate 53. The controller controls the drive motor 51 to rotate, thereby driving the electric telescopic clamping plate 53 to rotate. This causes the boring tool 55 on the boring bar 54 to perform boring operation on the workpiece 47, while simultaneously driving the active disk 56 to rotate, causing the driven disk to rotate synchronously.

[0060] During the boring operation, the controller controls the fan blades 22 to rotate, thereby generating negative pressure. This causes the chips generated at the machining point to enter the fixed box 21 and be collected by the filter screen 210. When the active disk 56 rotates and moves closer to the follower disk 29, it drives the follower disk 29 to rotate, thereby causing the pressure plate 28 and the spring cylinder 27 to rotate synchronously. At this time, the follower disk 29 and the pressure plate 28 rotate along the spiral section of the screw 24 and move to the right, which cools the inside of the spring cylinder 27. The lubricating oil is extruded and transported through the oil outlet pipe 211 to the interior of the boring bar 54 and the boring tool 55. Finally, it flows out from the interior of the boring tool 55 to cool it down, thereby preventing the boring tool 55 from sticking to the chips under the high temperature generated during operation. This avoids damage to the machined surface caused by continuing boring and machining at this time. On the other hand, under the transmission action of the connecting rod 26, the conductive slip ring 25 is pushed to continue to move to the right along the smooth section of the screw 24, making intermittent contact with the conductive sheet of the smooth section.

[0061] When the conductive slip ring 25 contacts the conductive sheet, the controller's current is transmitted to the conductive slip ring 25 through the conductive sheet, and then ultimately to the electric telescopic rod, controlling the spring-loaded electric telescopic rod 33 to extend. This pushes the filter screen 210 to the right, compressing the telescopic spring 32. Simultaneously, the magnet on the green plate pushes the magnetic block 313 to the right, causing the pull rope 310 to move synchronously. At this time, the pull rope 310 pulls the telescopic scraper 38, causing the arc-shaped tube 36 to compress the tension spring 37 and move it upwards along the ring 35, scraping away large debris such as strips adhering to the surface of the filter screen 210. When the conductive slip ring 25 is not in contact with the conductive sheet, the spring-loaded electric telescopic rod 33... 3. Reset: The filter screen 210 moves to the left under the restoring force of the telescopic spring 32. At this time, the magnetic force between the magnet on the filter screen 210 and the magnetic block 313 decreases. Under the gravity of the gravity block 39, the pull rope 310 moves downward, thereby driving the telescopic scraper 38 and the arc tube 36 to move downward along the ring 35, scraping the debris on the filter screen 210 downward. On the other hand, the filter screen 210 drives the push rod 212 to push the spring push plate 311 to the left to open the channel of the collection box 312, allowing the falling debris to enter the collection box 312, completing the collection of larger strip-shaped debris, while smaller debris enters the external collector through the filter screen 210.
