Description

Technical Field

[0001] This invention relates to the field of turning machine tool technology, and more particularly to low-wear turning machine tools. Background Technology

[0002] When machining workpieces of a fixed length on a lathe, there are two main issues: First, selecting raw material that exceeds the actual size of the workpiece and then cutting off the excess, resulting in material waste and increased costs. Second, using conventional methods to clamp the fixed-size raw material, the outer surface cannot be machined in one go and needs to be turned around and clamped twice. Turning around and clamping requires a certain amount of time for adjustment and alignment, and there is also a certain deviation in the concentricity of the outer surface between the two machining operations, which can easily lead to quality problems.

[0003] In addition, existing lathes typically require a large amount of cutting fluid for cooling, lubrication, and chip removal during turning operations. Most lathes are only equipped with simple collection tanks, and the cutting fluid and chips mix and flow directly into the collection tank, lacking an effective online filtration and recycling system. On the one hand, the cutting fluid is contaminated by chips or carried away with them after a single use, resulting in huge consumption and significantly increasing production costs. On the other hand, the viscous mixture of metal chips and cutting fluid accumulates in the collection tank, making cleaning labor-intensive and inefficient.

[0004] Therefore, there is an urgent need for low-wear turning machines to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a low-wear turning machine tool that eliminates the need for raw material processing allowance, reduces material waste and costs, and improves processing quality and work efficiency; allows for one-time clamping of the workpiece to complete the outer surface processing, avoiding turning and adjustment, improving efficiency and ensuring concentricity; enables the filtration and circulation of turning fluid, reducing consumption and production costs; and allows for centralized cleaning of iron filings, reducing labor intensity and improving cleaning efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution: A low-wear turning machine tool includes a frame, a drive mechanism, and a clamping mechanism, a waste collection mechanism, and a liquid recovery mechanism mounted on the frame.

The center center and the movable center are coaxially arranged and can clamp and position the center of the left and right ends of a workpiece of a fixed length. The driving mechanism is configured to drive the base to rotate around its axis, thereby causing the workpiece and the movable center to rotate synchronously. The waste collection mechanism includes a collection bin and a filter plate. The filter plate is located inside the collection bin and directly below the clamping mechanism. The filter plate can collect the iron filings that fall off the workpiece during machining and allow the cutting fluid to permeate downwards through the filter holes of the filter plate.

The right positioning assembly also includes: A first spring is disposed within the base. The central tip extends in the left-right direction. The right end of the central tip is elastically connected to the base through the first spring and is slidably disposed within the base. The left end of the central tip extends out of the base toward the workpiece. Three end-face positioning tips extend along the left-right direction and are evenly distributed around the center tip, and are fixed to the base at the end facing the workpiece; the tailstock moves along the left-right direction, driving the movable tip to push the workpiece to move along its axial direction to compress the first spring, and the right end face of the workpiece simultaneously abuts against the three end-face positioning tips to achieve limiting positioning.

[0008] As an alternative solution for low-wear turning machine tools, the base includes: The handle is detachably and fixedly connected to the chuck. The handle has a mounting groove extending in the left-right direction and a first external thread on the outside. The first spring is disposed in the mounting groove and one end is connected to the bottom wall of the mounting groove. The right end of the center tip is slidably disposed in the mounting groove and connected to the other end of the first spring. The outer side of the center tip has an integrally formed annular boss. The pressure cap nut has a connecting hole extending in the left-right direction. One end of the connecting hole has a first internal thread that matches the first external thread. The other end of the connecting hole allows the left end of the center tip to pass through. The hole wall of the connecting hole has an annular limiting groove that matches the annular boss to prevent the center tip from disengaging from the handle. The end face of the pressure cap nut facing the workpiece has three mounting holes, and the three end face positioning tips are threadedly connected to the three mounting holes respectively.

[0009] As an alternative solution for a low-wear turning machine tool, the low-wear turning machine tool further includes a brute-force mechanism and a support frame, the support frame extending along the left-right direction and fixed to the machine frame; the brute-force mechanism includes: The movable seat is slidably connected to the support frame in the left-right direction; A pressure plate is connected to the lower side of the movable seat. The pressure plate is located inside the collection chamber and slides against the filter plate. The second spring has its two ends connected to the movable seat and the support frame, respectively; The transmission assembly is used to transmit the power output by the drive mechanism to the movable seat, which drives the movable seat and the pressure plate to move to the left away from the iron filings accumulation by a predetermined length, and stretches the second spring to store energy; the second spring rebounds and pulls the pressure plate to the right closer to the iron filings accumulation, so as to compact the iron filings on the filter plate.

[0010] As an optional solution for a low-wear turning machine tool, the chuck has an annular groove on its exterior, and the inner wall of the annular groove is integrally formed with chain teeth; the transmission assembly includes: A threaded rod extends in the left-right direction and has a second external thread on its exterior. The threaded rod passes through the movable seat, and its two ends are rotatably connected to the two ends of the support frame. The second spring is sleeved on the threaded rod. A sprocket is fixedly fitted onto one end of the threaded rod; A drive chain is wound around and meshes with the sprocket and the chain teeth. The rotation of the chuck can drive the drive chain to move and the threaded rod to rotate. An opening and closing structure is provided inside the movable seat. The opening and closing structure has a second internal thread that is adapted to the second external thread. The opening and closing structure can switch between a closed state and an open state. When the opening and closing structure is in the closed state, it is threadedly engaged with the threaded rod. The rotation of the threaded rod can drive the movable seat to move to the left. When the opening and closing structure is in the open state, it is separated from the threaded rod, and the threaded rod is disengaged from the movable seat. The second spring pulls the movable seat and the pressure plate to automatically reset to the right.

[0011] As an alternative solution for a low-wear turning machine tool, the low-wear turning machine tool also includes a power supply, and the movable seat is provided with a clearance hole; the opening and closing structure includes: Two first electromagnets are fixedly connected to the upper and lower inner walls of the movable base, respectively, and both first electromagnets are electrically connected to the power supply.

The two magnetic movable blocks are provided with semi-circular slots facing each other, and the inner wall of the semi-circular slots is provided with the second internal thread. The threaded rod passes through the clearance hole and the two semi-circular slots. Two reset elastic elements are provided. The first electromagnet is elastically connected to the corresponding magnetic movable block through the reset elastic element. When the first electromagnet is energized, it repels the magnetic movable block, and the two semi-circular latches come together to form a closed state. When the first electromagnet is de-energized, the two reset elastic elements pull the two magnetic movable blocks apart to form an open state.

[0012] As an alternative solution for a low-wear turning machine tool, the two magnetic movable blocks are provided with wedge-shaped notches facing each other, and the movable seat is provided with a clearance opening; the pressing mechanism also includes an unlocking component, which includes a support rod and a wedge block. The support rod extends along the left-right direction, and its two ends are respectively connected to the left side of the support frame and the wedge block. The wedge block can pass through the clearance opening and extend between the two wedge notches, and push the two magnetic movable blocks to separate from each other to form a gap.

[0013] As an optional solution for low-wear turning machine tools, the liquid recovery mechanism also includes: A pad is installed inside the recycling bin, and the pad is equipped with water passage holes; The third spring has its two ends connected to the bottom wall of the recycling bin and the underside of the pad, respectively. The sponge is placed inside the recycling bin, located above the pad and below the filter plate; A wedge-shaped strip is fixedly connected to the pad. A wedge plate is connected to the left side of the pressure plate, and the wedge plate has an inclined surface that is lower on the left and higher on the right. When the pressure plate moves to the left, it can drive the wedge plate to move synchronously. The inclined surface contacts the wedge strip, pushes the wedge strip, and drives the pad to move upward to squeeze the sponge, while simultaneously stretching the third spring. When the pressure plate returns to its original position to the right, the third spring pulls the pad downward to fall back, and the sponge returns to its relaxed liquid storage state.

[0014] As an optional solution for low-wear turning machine tools, the pressure plate has a hollow structure and a strip-shaped clearance opening on its lower side; the pressure block mechanism also includes a clearing impact assembly, which includes: The second electromagnet is fixed to the inner top wall of the pressure plate and is electrically connected to the power supply. The iron plate is slidably connected to the inner wall of the pressure plate. The fourth spring has its two ends connected to the inner bottom wall of the pressure plate and the iron plate, respectively. The impact plate is fixedly connected to the lower side of the iron plate; When the second electromagnet is energized, it attracts the iron plate and stretches the fourth spring to store energy; when the second electromagnet is de-energized, the fourth spring resets, drives the iron plate to move downward, and causes the impact plate to pass through the strip-shaped clearance and impact the filter plate.

[0015] As an optional solution for a low-wear turning machine tool, the low-wear turning machine tool also includes a controller, and the pressure block mechanism also includes a vibration sensor and a collision block. The vibration sensor is located on the left side of the pressure plate; the collision block is fixed on the frame and located at the chip accumulation area; the vibration sensor is used to detect the vibration data of the pressure plate impacting the chips or the collision block. The drive mechanism, the vibration sensor, and the power supply are all electrically connected to the controller. The controller can receive vibration data and control the start and stop of the drive mechanism and the on and off of the power supply.

[0016] The beneficial effects of this invention are: This invention provides a low-wear turning machine tool. First, a fixed-length workpiece is placed in the clamping mechanism. The tailstock of the left positioning component slides and adjusts its position along the left-right direction of the machine frame, so that the movable center and the center center of the right positioning component respectively press against the center of the left and right ends of the workpiece. The movable center and the center center cooperate to achieve coaxial positioning of the workpiece, determining the workpiece's rotation center in one operation. Fixed-length raw materials do not require excess machining allowance, reducing material waste from the source. The drive mechanism drives the base to rotate around its axis, and the base drives the center center to rotate synchronously. The center center drives the workpiece and the movable center to rotate together, allowing the turning tool to perform continuous turning machining on the outer surface of the workpiece in one operation. No need for re-clamping, saving adjustment and alignment time, while ensuring the concentricity of the workpiece's outer diameter during machining, preventing eccentricity and movement of the workpiece during processing, and eliminating machining accuracy defects caused by secondary clamping. During machining, the cutting fluid is sprayed onto the machining area through a nozzle, carrying iron filings downwards onto the filter plate of the waste collection mechanism. The filter plate, located directly below the clamping mechanism, catches the iron filings and allows the cutting fluid to permeate downwards through its pores into the collection chamber. The recovery chamber of the liquid recovery mechanism collects the cutting fluid filtered by the filter plate. A circulation pump then returns the purified cutting fluid from the recovery chamber to the nozzle for reuse, significantly reducing cutting fluid consumption. Iron filings remain on the filter plate surface for easy cleaning, reducing the accumulation of viscous mixtures. This low-wear turning machine tool uses two-end center positioning for fixed-length workpieces, eliminating the need for raw material machining allowances, reducing material waste and costs, and improving machining quality and operating efficiency. The workpiece is clamped in one operation to complete the outer surface machining, avoiding turning and adjustment, improving efficiency and ensuring concentricity. The collection chamber, filter plate, and recovery chamber work together to achieve cutting fluid filtration and circulation, reducing consumption, production costs, facilitating centralized iron filings cleaning, reducing labor intensity, and improving cleaning efficiency.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3As shown, this embodiment provides a low-wear turning machine tool, which includes a frame 1, a drive mechanism 2, and a clamping mechanism 3, a waste collection mechanism 4, and a liquid recovery mechanism 5 disposed on the frame 1. The clamping mechanism 3 includes a left positioning component 31 and a right positioning component 32. The left positioning component 31 includes a tailstock 311 and a movable center 312. The tailstock 311 is slidably disposed on the frame 1 in the left-right direction, and the movable center 312 is rotatably connected to the tailstock 311. The right positioning component 32 includes a base 321 and a center center 322. The base 321 is rotatably connected to the frame 1, and the center center 322 is mounted on the base 321. The center center 322 and the movable center 312 are connected in the same direction. The shaft arrangement is capable of clamping and positioning the center of the left and right ends of the workpiece of a fixed length. The drive mechanism 2 is used to drive the base 321 to rotate around its axis, thereby driving the workpiece and the movable center 312 to rotate synchronously. The waste collection mechanism 4 includes a collection chamber 41 and a filter plate 42. The filter plate 42 is set in the collection chamber 41 and located directly below the clamping mechanism 3. The filter plate 42 can receive the iron filings that fall off the workpiece during processing and allow the cutting fluid to permeate downward through the filter holes of the filter plate 42. The liquid recovery mechanism 5 includes a recovery chamber 51 and a circulation pump. The recovery chamber 51 is set below the filter plate 42 and is used to receive the cutting fluid filtered by the filter plate 42. The inlet end of the circulation pump is connected to the recovery chamber 51, and the outlet end is connected to the nozzle facing the workpiece.

[0024] When using this low-wear turning machine tool, the fixed-length workpiece is first placed in the clamping mechanism 3. The tailstock 311 of the left positioning component 31 slides and adjusts its position along the left and right directions of the frame 1, so that the movable center 312 and the center center 322 of the right positioning component 32 respectively press against the center of the left and right ends of the workpiece. The movable center 312 and the center center 322 cooperate to achieve coaxial positioning of the workpiece, and determine the rotation center of the workpiece in one go. Fixed-length raw materials do not need to reserve extra machining allowance, reducing material waste from the source. The drive mechanism 2 drives the base 321 to rotate around its axis. The base 321 drives the center center 322 to rotate synchronously. The center center 322 drives the workpiece and the movable center 312 to rotate together. The turning tool can then perform continuous turning machining on the outer surface of the workpiece in one go without turning around and re-clamping, saving adjustment and alignment time. At the same time, it ensures the concentricity of the outer diameter of the workpiece, prevents the workpiece from becoming eccentric or moving during the machining process, and eliminates machining accuracy defects caused by secondary clamping. During the processing, the cutting fluid is sprayed onto the processing area through the nozzle, carrying iron filings as it falls downwards onto the filter plate 42 of the waste collection mechanism 4. The filter plate 42 is located directly below the clamping mechanism 3. The filter plate 42 receives the iron filings and allows the cutting fluid to permeate downwards through the filter holes into the collection chamber 41. The recovery chamber 51 of the liquid recovery mechanism 5 receives the cutting fluid filtered by the filter plate 42. The circulation pump re-transports the purified cutting fluid in the recovery chamber 51 back to the nozzle for recycling, significantly reducing the consumption of cutting fluid. The iron filings remain on the surface of the filter plate 42 for easy centralized cleaning, reducing the accumulation of viscous mixtures. This low-wear turning machine tool uses two-end centers to position and fix the length of the workpiece, eliminating the need for raw material processing allowance, reducing material waste and costs, and improving processing quality and operating efficiency; the workpiece is clamped in one go to complete the outer surface processing, avoiding turning and adjustment, improving efficiency and ensuring concentricity; the collection chamber 41, filter plate 42 and recovery chamber 51 work together to realize the filtration and circulation of turning fluid, reducing consumption, reducing production costs, facilitating the centralized cleaning of iron filings, reducing labor intensity and improving cleaning efficiency.

[0025] In this embodiment, the waste collection mechanism 4 also includes a baffle plate, which is disposed on the side of the collection chamber 41. The baffle plate can be opened or closed to open or close the collection chamber 41. When closed, the baffle plate on the side of the collection chamber 41 can seal the collection chamber 41, effectively preventing iron filings and cutting fluid from splashing outwards during the machining process, avoiding waste liquid and waste residue from spilling and polluting the surrounding environment of the machine tool, and reducing the amount of on-site cleaning work. When the baffle plate is open, it can open the side space of the collection chamber 41, making it convenient for operators to directly remove the iron filings accumulated on the filter plate 42, simplifying the waste cleaning process and improving the convenience of operation.

[0026] In this embodiment, the liquid recovery mechanism 5 also includes a sealing plate, which is disposed on the side of the recovery chamber 51. The sealing plate can be opened or closed to open or seal the recovery chamber 51. When closed, the sealing plate on the side of the recovery chamber 51 can seal the recovery chamber 51, preventing external dust and debris from falling into the recovery chamber 51 and contaminating the machining fluid, thus ensuring the cleanliness of the recycled liquid. When the sealing plate is open, the side of the recovery chamber 51 can be opened, making it easier for personnel to clean internal deposits and improving maintenance convenience.

[0027] like Figure 3 and Figure 4 As shown, the drive mechanism 2 includes a drive motor, a main shaft 21, and a chuck 22. The chuck 22 is connected to the output end of the drive motor via the main shaft 21. The base 321 is detachably and fixedly connected to the chuck 22. The right positioning component 32 also includes a first spring 323 and three end-face positioning tips 324. The first spring 323 is disposed inside the base 321. The center tip 322 extends in the left-right direction. The right end of the center tip 322 is elastically connected to the base 321 via the first spring 323 and is slidably disposed inside the base 321. The left end of the center tip 322 extends out of the base 321 and faces the workpiece. The three end-face positioning tips 324 all extend in the left-right direction and are evenly distributed along the circumference of the center tip 322, and are fixed to the end of the base 321 facing the workpiece. The tailstock 311 moves in the left-right direction, driving the movable tip 312 to push the workpiece to move along its axial direction and compress the first spring 323. The right end face of the workpiece simultaneously abuts against the three end-face positioning tips 324 to achieve limiting positioning. The chuck 22 of the drive mechanism 2 is detachably and fixedly connected to the base 321, which facilitates quick replacement of the appropriate base 321 according to different workpiece specifications, improving versatility. The first spring 323 of the right positioning component 32 enables the center tip 322 to have elastic extension and retraction capabilities to achieve adaptive clamping. The tailstock 311 can form a buffer during the workpiece clamping process to avoid damage to the workpiece end face by rigid clamping. During clamping, the workpiece continuously squeezes the center tip 322 to the right and retracts it into the base 321 until the three end face positioning tips 324 evenly distributed around the center tip 322 abut against the right end face of the workpiece, forming end face center clamping and multi-point support positioning, ensuring accurate axial clamping and positioning of the workpiece, and preventing the workpiece from shifting or deviating.

[0028] It is worth noting that during the machining process, the first spring 323 continuously compresses and pushes the center tip 322 to the left, while the three end face positioning tips 324 always press against the right end face of the workpiece to ensure stable torque transmission. The workpiece axis and the lathe spindle 21 axis remain aligned. The operator can control the tool to complete the machining of all outer surfaces of the workpiece in one go without secondary clamping. This eliminates the need for secondary adjustment and alignment, as well as the need to reserve excess machining allowance, effectively reducing raw material loss. At the same time, it avoids quality problems such as concentricity deviation and tool marks caused by secondary clamping.

[0029] It is worth noting that the chuck 22 adopts a three-jaw clamping structure, and the three jaws can move radially synchronously. When clamping the base 321, it can automatically center itself, ensuring that the workpiece, the base 321 and the spindle 21 remain coaxial, avoiding machining errors caused by clamping eccentricity, and ensuring the concentricity of the workpiece's outer diameter machining. The three-jaw clamping method has a uniform clamping force distribution, and the clamping is stable and reliable. It can adapt to the clamping requirements of bases 321 with different outer diameter specifications, and the changeover adjustment is convenient.

[0030] like Figure 4 and Figure 5 As shown, the base 321 includes a handle 3211 and a cap nut 3212. The handle 3211 is detachably and fixedly connected to the chuck 22. The handle 3211 has a mounting groove 32111 extending in the left-right direction, and the handle 3211 has a first external thread 32112 on its outer side. A first spring 323 is disposed in the mounting groove 32111, with one end connected to the bottom wall of the mounting groove 32111. The right end of the center tip 322 is slidably disposed in the mounting groove 32111 and connected to the other end of the first spring 323. An annular boss 3220 is integrally formed on the outside of the center tip 322. The female part 3212 has a connecting hole 32121 extending in the left and right direction. One end of the connecting hole 32121 has a first internal thread 32122 that is adapted to the first external thread 32112. The other end of the connecting hole 32121 allows the left end of the center tip 322 to pass through. The hole wall of the connecting hole 32121 has an annular limiting groove 32123 that is adapted to the annular boss 3220 to limit the center tip 322 from disengaging from the handle 3211. The end face of the pressure cap nut 3212 facing the workpiece has three mounting holes. The three end face positioning tips 324 are threadedly connected to the three mounting holes respectively. The handle 3211 and the pressure cap nut 3212 are assembled by threaded assembly to form the base 321, which facilitates the inspection and replacement of the first spring 323 and the center tip 322 inside the mounting groove 32111. The annular limiting groove 32123 cooperates with the annular boss 3220 to restrict the center tip 322 from coming out, ensuring stable assembly. The end face positioning tip 324 is threaded on the pressure cap nut 3212, which is easy to disassemble and replace individually. The overall structure is easy to disassemble and assemble, which is conducive to the maintenance and replacement of parts.

[0031] like Figure 2 , Figure 3 and Figure 6As shown, the low-wear turning machine tool also includes a pressing mechanism 6 and a support frame 7. The support frame 7 extends in the left-right direction and is fixed on the machine frame 1. The pressing mechanism 6 includes a movable seat 61, a pressing plate 62, a second spring 63, and a transmission assembly 64. The movable seat 61 is slidably connected to the support frame 7 in the left-right direction. The pressing plate 62 is connected to the lower side of the movable seat 61 and is located in the collection chamber 41 and slides against the filter plate 42. The two ends of the second spring 63 are respectively connected to the movable seat 61 and the support frame 7. The transmission assembly 64 is used to transmit the power output from the drive mechanism 2 to the movable seat 61, driving the movable seat 61 and the pressing plate 62 to move to the left away from the chip accumulation area by a preset length, and causing the second spring 63 to stretch and store energy. The second spring 63 rebounds and resets, pulling the pressing plate 62 to the right and closer to the chip accumulation area to compact the chips on the filter plate 42. The transmission assembly 64 transmits the power of the drive mechanism 2 to the movable seat 61, which drives the pressure plate 62 to move in the left and right directions. The support frame 7 provides stable sliding support for the movable seat 61 and automatically resets in conjunction with the second spring 63. This enables the pressure plate 62 to compact the iron filings on the surface of the filter plate 42, reducing the space occupied by the iron filings. The compacted iron filings are easy to transport in a centralized manner, reducing the frequency of cleaning. At the same time, it prevents loose iron filings from clogging the pores of the filter plate 42, ensuring smooth penetration and filtration of the machining fluid.

[0032] like Figure 3 , Figure 6 and Figure 7As shown, the chuck 22 has an annular groove on its exterior, and chain teeth are integrally formed on the inner wall of the annular groove; the transmission assembly 64 includes a threaded rod 641, a sprocket 642, a transmission chain 643, and an opening and closing structure 644. The threaded rod 641 extends in the left-right direction and has a second external thread on its exterior. The threaded rod 641 passes through the movable seat 61, and its two ends are rotatably connected to the two ends of the support frame 7, respectively. A second spring 63 is sleeved on the threaded rod 641; the sprocket 642 is fixedly sleeved on one end of the threaded rod 641; the transmission chain 643 is wound around and meshes with the sprocket 642 and the chain teeth. The rotation of the chuck 22 can drive the transmission chain. 643 moves and threaded rod 641 rotates; opening and closing structure 644 is set in the movable seat 61, and opening and closing structure 644 is provided with a second internal thread 64422 adapted to the second external thread. Opening and closing structure 644 can switch between closed and open states. When the opening and closing structure 644 is in the closed state, it is threadedly engaged with threaded rod 641. Rotation of threaded rod 641 can drive movable seat 61 to move to the left; when the opening and closing structure 644 is in the open state, it is separated from threaded rod 641 by clearance. Threaded rod 641 is disengaged from movable seat 61 by transmission. Second spring 63 pulls movable seat 61 and pressure plate 62 to automatically reset to the right. When the chuck 22 rotates, it drives the sprocket 642 and the threaded rod 641 to move synchronously through the chain teeth and the transmission chain 643. No additional drive device is required. The opening and closing structure 644 switches the working state to achieve threaded engagement or clearance separation with the threaded rod 641. When threaded engagement, the threaded rod 641 rotates and drives the moving seat 61 to move to the left, stretching the second spring 63 to store energy. When clearance separation, the second spring 63 pulls the moving seat 61 to return to the right. This cycle drives the pressure plate 62 to compact the iron filings. The structure is compact and the action coordination is high.

[0033] like Figure 7 and Figure 8As shown, the low-loss turning machine tool also includes a power supply. The movable base 61 has a clearance hole 611. The opening and closing structure 644 includes two first electromagnets 6441, two magnetic movable blocks 6442, and two reset elastic elements. The two first electromagnets 6441 are fixedly connected to the upper and lower inner walls of the movable base 61, respectively, and both first electromagnets 6441 are electrically connected to the power supply. The two magnetic movable blocks 6442 are disposed between the two first electromagnets 6441 and are slidably connected to the inner side wall of the movable base 61. The two magnetic movable blocks 6442 have semi-circular notches 611 facing each other. 4421, and the inner wall of the semi-circular bayonet 64421 is provided with a second internal thread 64422, and the threaded rod 641 passes through the clearance hole 611 and the two semi-circular bayonet 64421; the first electromagnet 6441 is elastically connected to the corresponding magnetic movable block 6442 through the reset elastic element. When the first electromagnet 6441 is energized, it repels the magnetic movable block 6442, and the two semi-circular bayonet 64421 move closer to each other to the closed state; when the first electromagnet 6441 is de-energized, the two reset elastic elements pull the two magnetic movable blocks 6442 to separate from each other to the open state. The power supply controls the first electromagnet 6441 to switch the working state of the opening and closing structure 644 by turning it on and off. When energized, it repels the magnetic movable block 6442, causing the semi-circular slots 64421 of the two magnetic movable blocks 6442 to close and engage with the threaded rod 641. When de-energized, the reset elastic element pulls the magnetic movable blocks 6442 apart to release the transmission. The diameter of the clearance hole 611 is larger than the diameter of the threaded rod 641, leaving room for the threaded rod 641 to move. The electrical control switching response is rapid, which makes it easy to flexibly adjust the timing of the pressure plate 62 compacting the iron filings.

[0034] In this embodiment, the opening and closing structure 644 further includes a damping layer, which is disposed on the inner sidewall of the movable seat 61. The damping layer laid on the inner sidewall of the movable seat 61 can increase the frictional resistance when the magnetic movable block 6442 slides, effectively preventing the magnetic movable block 6442 from falling back on its own under the action of gravity, ensuring that the opening and closing structure 644's clutch switching is precise and controllable, while buffering sliding impacts and reducing wear on components.

[0035] like Figure 8 and Figure 9As shown, two magnetic movable blocks 6442 are provided with wedge-shaped notches 64423 facing each other, and the movable seat 61 is provided with a clearance opening 612. The pressing mechanism 6 also includes an unlocking component 65, which includes a support rod 651 and a wedge block 652. The support rod 651 extends in the left-right direction, and its two ends are respectively connected to the left side of the support frame 7 and the wedge block 652. The wedge block 652 can pass through the clearance opening 612 and extend between the two wedge notches 64423, pushing the two magnetic movable blocks 6442 to separate and form a gap. When the movable seat 61 moves to the left, the relatively stationary wedge block 652 extends between the two wedge notches 64423 through the clearance opening 612, and the relative motion pushes the two magnetic movable blocks 6442 to separate, realizing mechanical unlocking. The unlocking component 65 can cooperate with the power supply to ensure that the movable seat 61 rebounds smoothly and effectively improves the working stability of the pressing mechanism 6.

[0036] like Figure 3 , Figure 10 and Figure 11 As shown, the liquid recovery mechanism 5 also includes a pad 52, a third spring 53, a sponge 54, a wedge strip 55, and a wedge plate 56. The pad 52 is disposed inside the recovery chamber 51 and has water passage holes 521. The two ends of the third spring 53 are respectively connected to the bottom wall of the recovery chamber 51 and the lower side of the pad 52. The sponge 54 is disposed inside the recovery chamber 51, located above the pad 52 and below the filter plate 42. The wedge strip 55 is fixedly connected to the pad 52. The wedge plate 56 is connected to the left side of the pressure plate 62 and has an inclined surface that is lower on the left and higher on the right. When the pressure plate 62 moves to the left, it can drive the wedge plate 56 to move synchronously. The inclined surface contacts the wedge strip 55, pushes the wedge strip 55, drives the pad 52 to move upward and squeeze the sponge 54, and simultaneously stretches the third spring 53. When the pressure plate 62 returns to the right, the third spring 53 pulls the pad 52 downward and the sponge 54 returns to a relaxed liquid storage state. The pressure plate 62 moves to the left, causing the wedge plate 56 to push the wedge strip 55, which in turn causes the pad 52 to rise and squeeze the sponge 54 to expel the adsorbed cutting fluid. After the pressure plate 62 returns to its original position to the right, the third spring 53 causes the pad 52 to fall, and the sponge 54 regains its water absorption and filtration capacity, once again receiving fine impurities and waste liquid flowing down from the filter plate 42. The squeezing action and the compaction of iron chips are linked, utilizing existing power without additional drive. The sponge 54 periodically stores and squeezes liquid, continuously trapping fine iron chips, effectively improving the filtration and circulation effect of the cutting fluid. It is worth noting that the maximum moving distance of the pressure plate 62 corresponds to the point when the wedge strip 55 contacts the highest position of the inclined surface of the wedge plate 56.

[0037] like Figure 6As shown, the pressure plate 62 has a hollow structure, and a strip-shaped clearance opening 621 is provided on the lower side of the pressure plate 62. The pressure block mechanism 6 also includes a blockage clearing impact assembly 66, which includes a second electromagnet 661, an iron plate 662, a fourth spring 663, and an impact plate 664. The second electromagnet 661 is fixed to the inner top wall of the pressure plate 62 and is electrically connected to the power supply. The iron plate 662 is slidably connected to the inner side wall of the pressure plate 62. The two ends of the fourth spring 663 are respectively connected to the inner bottom wall of the pressure plate 62 and the iron plate 662. The impact plate 664 is fixedly connected to the lower side of the iron plate 662. When the second electromagnet 661 is energized, it attracts the iron plate 662 and stretches the fourth spring 663 to store energy. When the second electromagnet 661 is de-energized, the fourth spring 663 resets, drives the iron plate 662 to move downward, and drives the impact plate 664 to pass through the strip-shaped clearance opening 621 to impact the filter plate 42. The power supply controls the second electromagnet 661 to turn on and off. After the second electromagnet 661 is de-energized, the fourth spring 663 releases energy to push the impact plate 664 through the strip-shaped clearance opening 621 to strike the filter plate 42, causing micro-deformation within its safe lifespan. The vibration and impact force shake off impurities in the filter holes of the filter plate 42, preventing the filter holes from being blocked by impurities and ensuring smooth seepage of the machining fluid. In addition, the anti-clogging impact component 66 is integrated inside the pressure plate 62 and moves synchronously with the pressure plate 62 to achieve fixed-point anti-clogging during the movement.

[0038] like Figure 2 As shown, the low-wear turning machine tool also includes a controller, and the pressure block mechanism 6 includes a vibration sensor 67 and a collision block 68. The vibration sensor 67 is located on the left side of the pressure plate 62; the collision block 68 is fixed on the frame 1 and located at the chip accumulation area. The vibration sensor 67 is used to detect the vibration data of the pressure plate 62 impacting the chips or the collision block 68. The drive mechanism 2, the vibration sensor 67, and the power supply are all electrically connected to the controller. The controller can receive the vibration data and control the start and stop of the drive mechanism 2 and the on / off state of the power supply. The vibration sensor 67 collects the vibration signal generated by the pressure plate 62 contacting the chips or the collision block 68 and transmits it to the controller. The controller adjusts the start and stop of the drive mechanism 2 and the on / off state of the power supply according to the acquired vibration data, automatically and orderly executing the compaction action and the unblocking action, forming a closed-loop automatic control, reducing manual intervention, and making the machine tool operation more intelligent and stable.

[0039] In this embodiment, the controller can be a PLC or a microcontroller controller, etc., and no specific limitation is made here.

[0040] It should be noted that the vibration force generated when the pressure plate 62 springs back and squeezes the iron filings is moderate and stable. This vibration intensity is within the tolerance range of the vibration sensor 67 during long-term stable operation, and will not cause damage to the internal components of the vibration sensor 67 or signal distortion. The vibration sensor 67 can stably collect this vibration data. In addition, when the pressure plate 62 moves to the left, the speed is slow and gentle, and the resulting vibration amplitude is extremely small, below the trigger threshold set by the controller, and cannot be detected by the vibration sensor 67.

[0041] In this embodiment, when the amount of iron filings is small, the pressure plate 62 impacts the collision block 68 after the second spring 63 returns to its original position; when the thickness of the iron filings is large, the pressure plate 62 directly impacts and squeezes the iron filings. In both working conditions, the vibration sensor 67 can collect the corresponding vibration data and transmit it to the controller. After the controller determines that the vibration data has reached the threshold, it synchronously controls the first electromagnet 6441 and the second electromagnet 661 to be energized; after the vibration disappears, the moving seat 61 moves to the left to the designated position to complete the mechanical unlocking, and the controller synchronously controls the first electromagnet 6441 and the second electromagnet 661 to be de-energized. The timing of the action is stable and controllable.

[0042] In this embodiment, a rubber pad is provided at the end of the collision block 68 facing the pressure plate 62. The rubber pad buffers the impact load when the pressure plate 62 rebounds and impacts, avoids rigid contact between the collision block 68 and the pressure plate 62, reduces impact wear on the pressure plate 62 and the collision block 68, and extends the service life of each component; it also reduces the noise generated by the impact, making the vibration data collected by the vibration sensor 67 accurate and ensuring the controller makes accurate judgments.

[0043] In this embodiment, the low-loss turning machine tool also includes a soft-shielded wire. The drive mechanism 2, vibration sensor 67, and power supply are all electrically connected to the controller through the soft-shielded wire. The wire has sufficient length to move and is fixed to the support frame 7 with wire clips to prevent the wire from being torn, worn, or stuck in the transmission component 64. In addition, the wire will not come into contact with iron filings on the left side of the pressure plate 62, which prevents the soft-shielded wire from being scratched and damaged by iron filings and ensures long-term reliable electrical connection.
