[0001] This invention relates to the field of CNC lathe technology, specifically to a CNC lathe with a chip removal structure. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] For example, CN213257158U discloses an easy-to-maintain, low-noise CNC lathe. It is equipped with an inspection side cover, a hinge seat, a support rod, and a rod sleeve.

The bottom end of the support rod is supported inside the CNC lathe body, and the support rod supports the inspection side cover, thereby facilitating the maintenance of the CNC lathe.

[0004] The aforementioned patent does not include a cleaning mechanism on the slide rails of the CNC lathe. During machining, the CNC lathe generates a large amount of waste chips, which fall onto the slide rails. When the moving seat of the CNC lathe moves on the slide rails, the debris on the slide rails obstructs the moving seat, thereby affecting the machining of the CNC lathe. Summary of the Invention

[0005] The purpose of this invention is to provide a CNC lathe with a chip cleaning structure to solve the problem mentioned in the background art that existing CNC machine tools do not clean chips on the slide rails.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CNC lathe with a chip-removing structure, comprising a machine body and a second rack and pinion, wherein a motor is installed inside the machine body, a chuck is fixedly connected to the output end of the motor, a center seat is installed on the side of the machine body away from the motor, and a control box is installed on the side of the machine body near the center seat.

The top of the movable base is slidably connected to a clamping platform via a slider. The bottom of the clamping platform has a moving groove that matches the slider on the top of the movable base.

[0008] Preferably, cleaning rollers are movably connected to both sides of the movable seat via rotating shafts. One end of the cleaning roller is fixedly connected to a first gear. A first rack is meshed with the outer side of the first gear. One side of the first gear is movably connected to the movable seat via a rotating shaft. Both sides of the first rack are fixedly connected to the machine body. A sliding groove is provided inside the movable seat for the first rack to slide.

[0009] Preferably, scrapers are fixedly connected to both sides of the movable seat, the scrapers are disposed on the top of the cleaning roller, and a spring is fixedly connected inside the movable seat, with a second rack rod fixedly connected to one end of the spring.

[0010] Preferably, a second gear is meshed with the outer side of the second rack, a first transmission rod is fixedly connected to one side of the second gear, the outer side of the first transmission rod is movably connected to the machine body through a bearing, a first synchronous pulley is fixedly connected to the bottom of the first transmission rod, the bottom of the first synchronous pulley is movably connected to the machine body through a rotating shaft, and a synchronous belt is sleeved on the outer side of the first synchronous pulley.

[0011] Preferably, a second synchronous pulley is sleeved on the inner side of the synchronous belt, a second transmission rod is fixedly connected to the top of the second synchronous pulley, the outer side of the second transmission rod is movably connected to the machine body through a bearing, and a cleaning rod is fixedly connected to the top of the second transmission rod.

[0012] Preferably, the bottom of the machine body is provided with an installation groove for the collection box to slide, the inside of the collection box is movably connected to a rotating plate via a rotating shaft, and one side of the collection box is movably connected to a handle via a rotating shaft.

[0013] Preferably, a magnetic rod is fixedly connected to one side of the handle, a protrusion is provided on the outer side of the magnetic rod, one side of the protrusion is fixedly connected to the machine body, and a roller is rotatably connected to the bottom of the collection box.

[0014] Preferably, the two sides of the roller are movably connected to the machine body via a rotating shaft, and the bottom of the machine body is provided with an inclined groove that matches the rotating plate.

[0015] Preferably, a door panel is movably connected to one side of the control box via a pivot, a lever is fixedly connected to one side of the door panel, the lever has a through groove for the fixed rod to slide, and connecting plates are fixedly connected to both ends of the fixed rod.

[0016] Preferably, the interior of the machine body has a sliding groove for the bottom slider of the connecting plate to slide, and a magnet is provided on one side of the door panel, with one side of the magnet being fixedly connected to the control box.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: When the moving seat moves, it drives the first gear to mesh with the first rack, thereby driving the cleaning roller to rotate and pushing the debris on the forward stroke to the side away from the moving seat, keeping the moving seat moving smoothly. By pulling out the collection box, when the rotation axis of the rotating plate at the bottom of the collection box moves to the position of the inclined groove, the rotating plate will rotate under the action of gravity, causing the bottom of the collection box to unfold. At this time, the waste in the collection box will be discharged. By pulling the door panel, the lever can be rotated, and the lever can move the fixed rod and the connecting plate. The connecting plate can move the components installed on its surface to the outside of the machine body. Since the space outside the control box is large, it is more convenient to maintain the control box.

[0018] 1. CNC lathes are widely used machine tools, mainly used for machining shaft-type workpieces. To clean the debris that falls onto the internal slide rails during machining, cleaning rollers and a first gear are installed on both sides of the moving base. When the first gear moves, it meshes with a first rack, thereby driving the cleaning rollers to rotate. Since the first rack is above the first gear, the first gear rotates clockwise when meshing with the first rack, pushing the debris on the forward stroke away from the moving base. At the same time, the cleaning rollers also come into contact with the scraper on top when rotating. The scraper scrapes away the debris stuck on the cleaning rollers, keeping the cleaning rollers clean. Through the above operations, the debris on the CNC machine tool can be collected and then cleaned in a centralized manner.

[0019] 2. CNC lathes are widely used machine tools, mainly used for machining shaft-type workpieces. When collecting the waste chips cleaned from the machine body's slide rails, a collection box is installed at the bottom of the machine body. When it is necessary to empty the waste chips in the collection box, the handle is turned to disengage the magnetic rod from the magnetically conductive protrusion, and then the collection box is pulled out. When the rotation axis of the rotating plate at the bottom of the collection box moves to the position of the inclined groove, the rotating plate will rotate under the action of gravity, causing the bottom of the collection box to unfold. At this time, the waste chips in the collection box will be discharged. In this way, the waste chips collected inside the CNC machine tool can be centrally discharged and cleaned.

[0020] 3. CNC lathes are widely used machine tools, mainly for machining shaft-type workpieces. When inspecting the control box inside the machine body, the door panel is rotated and opened by pulling it. After the top of the door panel disengages from the magnet, the door panel can be rotated further. The door panel can drive the lever to rotate, and the through groove inside the lever will contact the fixed rod. By moving the fixed rod, the fixed rod can drive the connecting plate to move. The connecting plate can move the components mounted on its surface to the outside of the machine body. Because the space outside the control box is relatively large, it is easier to maintain the control box. In this way, the control box in the CNC machine tool can be quickly inspected and repaired through the above operation. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1-7The present invention provides a technical solution: a CNC lathe with a chip removal structure, comprising a machine body 1 and a second rack 13, a motor 2 installed inside the machine body 1, a chuck 3 fixedly connected to the output end of the motor 2, a center seat 4 installed on the side of the machine body 1 away from the motor 2, and a control box 5 installed on the side of the machine body 1 close to the center seat 4.

[0033] The top of the machine body 1 is slidably connected to a movable base 6 via a slider. The bottom of the movable base 6 has a groove that matches the slider on the top of the machine body 1. The top of the movable base 6 is slidably connected to a clamping platform 7 via a slider. The bottom of the clamping platform 7 has a moving groove that matches the slider on the top of the movable base 6. Cleaning rollers 8 are movably connected to both sides of the movable base 6 via rotating shafts. One end of the cleaning roller 8 is fixedly connected to a first gear 9. A first rack 10 is meshed with the outer side of the first gear 9. One side of the first gear 9 is movably connected to the movable base 6 via a rotating shaft. Both sides of the first rack 10 are fixedly connected to the machine body 1. A sliding groove for the first rack 10 to slide is provided inside the movable base 6. Scrapers 11 are fixedly connected to both sides of the movable base 6. The scrapers 11 are positioned on top of the cleaning rollers 8. A spring 12 is fixedly connected inside the movable base 6. One side of the spring 12... A second rack 13 is fixedly connected to one end; a second gear 14 is meshed with the outer side of the second rack 13; a first transmission rod 15 is fixedly connected to one side of the second gear 14; the outer side of the first transmission rod 15 is movably connected to the machine body 1 via a bearing; a first synchronous pulley 16 is fixedly connected to the bottom of the first transmission rod 15; the bottom of the first synchronous pulley 16 is movably connected to the machine body 1 via a rotating shaft; a synchronous belt 17 is sleeved on the outer side of the first synchronous pulley 16; a second synchronous pulley 18 is sleeved on the inner side of the synchronous belt 17; a second transmission rod 19 is fixedly connected to the top of the second synchronous pulley 18; the outer side of the second transmission rod 19 is movably connected to the machine body 1 via a bearing; a cleaning rod 20 is fixedly connected to the top of the second transmission rod 19; the first gear 9 and the first rack 10 form a meshing transmission structure; the second synchronous pulley 18 forms a rotating structure with the machine body 1 via a rotating shaft.

[0034] In practice, CNC lathes are widely used machine tools, mainly used for machining shaft-type workpieces. In order to clean the waste chips that fall into the slide rail inside the machine body 1 during machining, cleaning rollers 8 and first gears 9 are set on both sides of the moving seat 6. When the first gear 9 moves, it will mesh with the first rack 10, thereby driving the cleaning rollers 8 to rotate. Since the first rack 10 is above the first gear 9, the first gear 9 will rotate clockwise when it meshes with the first rack 10, pushing the debris on the forward stroke to the side away from the moving seat 6. At the same time, the cleaning rollers 8 will also contact the scraper 11 at the top when rotating. The scraper 11 will scrape off the waste chips stuck on the cleaning rollers 8, keeping the cleaning rollers 8 clean. The cleaned waste chips will gather on both sides of the slide rail at the top of the machine body 1.

[0035] When the movable seat 6 moves and contacts the second rack 13, the second rack 13 will compress the spring 12 on one side. At the same time, the second rack 13 will mesh with the second gear 14, causing the first transmission rod 15 to drive the first synchronous pulley 16 to rotate. The first synchronous pulley 16 can drive the second synchronous pulley 18 to rotate through the synchronous belt 17. The second synchronous pulley 18 will drive the cleaning rod 20 to rotate through the second transmission rod 19. The rotating cleaning rod 20 will push away the waste chips accumulated on the slide rail of the machine body 1, causing them to fall to the bottom of the machine body 1. When the movable seat 6 moves away from the compression of the second rack 13, the spring 12 will return to its original position, thereby driving the cleaning rod 20 to return to its original position as well, preventing the movable seat 6 from contacting the cleaning rod 20 when moving. In this way, the waste chips on the CNC machine tool can be collected and then cleaned in a concentrated manner.

[0036] Please see Figures 1-4 The bottom of the body 1 has a mounting groove for the collection box 21 to slide. The inside of the collection box 21 is movably connected to a rotating plate 22 via a rotating shaft. One side of the collection box 21 is movably connected to a handle 23 via a rotating shaft. A magnetic rod 24 is fixedly connected to one side of the handle 23. A protrusion 25 is provided on the outer side of the magnetic rod 24. One side of the protrusion 25 is fixedly connected to the body 1. A roller 26 is rotatably connected to the bottom of the collection box 21. The two sides of the roller 26 are movably connected to the body 1 via rotating shafts. The bottom of the body 1 has a slanted groove 27 that matches the rotating plate 22. The protrusion 25 is made of magnetic material. The collection box 21 forms a rotating structure with the rotating plate 22 via the rotating shaft.

[0037] In practice, CNC lathes are widely used machine tools, mainly used for machining shaft-type workpieces. When collecting the waste chips cleaned off the slide rails of the machine body 1, a collection box 21 is set at the bottom of the machine body 1. When it is necessary to empty the waste chips in the collection box 21, the handle 23 is turned to drive the magnetic rod 24 to disengage from the magnetically conductive protrusion 25, and then the collection box 21 is pulled out. When the rotation axis of the rotating plate 22 at the bottom of the collection box 21 moves to the position of the inclined groove 27, the rotating plate 22 will rotate under the action of gravity, causing the bottom of the collection box 21 to unfold, and the waste chips in the collection box 21 will be discharged.

[0038] After discharge, the collection box 21 is pushed back into the machine body 1. When the rotating plate 22 at the bottom of the collection box 21 contacts the roller 26, the roller 26 will push the rotating plate 22 to rotate because the roller 26 is located at the highest point of the inclined groove 27. When the collection box 21 is completely inside the machine body 1, the rotating plate 22 will also rotate to a horizontal state, sealing the bottom of the collection box 21. Then, the handle 23 can be rotated to drive the magnetic rod 24 to contact the protrusion 25, so that the two are attracted together. The magnetic rod 24 can limit the collection box 21. In this way, the waste chips collected inside the CNC machine tool can be centrally discharged and cleaned through the above operation.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9 A door panel 28 is movably connected to one side of the control box 5 via a pivot. A lever 29 is fixedly connected to one side of the door panel 28. The lever 29 has a through groove 31 for sliding of a fixed rod 30. Connecting plates 32 are fixedly connected to both ends of the fixed rod 30. A sliding groove is provided inside the body 1 for sliding of the bottom slider of the connecting plate 32. A magnet 33 is provided on one side of the door panel 28. One side of the magnet 33 is fixedly connected to the control box 5. The control box 5 and the door panel 28 form a rotating structure via a pivot. The lever 29, the fixed rod 30 and the through groove 31 form a sliding structure. The door panel 28 is made of magnetic material.

[0040] In practice, a CNC lathe is a widely used machine tool, mainly used for machining shaft-type workpieces. When inspecting the control box 5 in the machine body 1, the door panel 28 is rotated and unfolded by pulling it. After the top of the door panel 28 disengages from the magnet 33, the door panel 28 can continue to rotate. The door panel 28 can drive the lever 29 to rotate. The through groove 31 inside the lever 29 will contact the fixed rod 30, causing the fixed rod 30 to move. The fixed rod 30 can then drive the connecting plate 32 to move. The connecting plate 32 can move the components mounted on its surface to the outside of the machine body 1. Since the space outside the control box 5 is large, it is more convenient to maintain the control box 5. After maintenance, the door plate 28 can be rotated to close. The door plate 28 can be pushed back into the control box 5 by the lever 29. When the magnetic door plate 28 contacts the magnet block 33, the door plate 28 can be limited. In this way, the control box 5 in the CNC machine tool can be quickly inspected and repaired through the above operation.

[0041] In summary, the workpiece is fixed on the chuck 3, the cutting tool is fixed on the clamping table 7, and then the machining program is input through the control box 5. The control box 5 can control the motor 2 to drive the chuck 3 to rotate. Through the movement and feed of the moving seat 6 and the clamping table 7, the cutting tool is driven to contact the rotating workpiece, and the workpiece fixed on the chuck 3 can be machined. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
