Description

Technical Field

[0001] This invention belongs to the field of machine tools, and specifically relates to a special CNC turning machine tool. Background Technology

[0002] When machining a workpiece, existing CNC turning machine tools require the workpiece to be clamped in the spindle chuck and driven by the spindle motor to rotate at high speed, providing the main cutting motion. Multiple turning tools (such as external turning tools, grooving tools, threading tools, etc.) are pre-installed on a rigid tool holder and, driven by a servo motor, perform programmed compound motions along precision guideways on the machine bed. When the tool cuts in, the workpiece in front of the tool tip undergoes severe plastic deformation under enormous stress, sliding along the tool's rake face and being "ploughed" upwards. When the local stress exceeds the material's strength limit, the chips are sheared and separated from the workpiece matrix. When turning materials with good plasticity such as ordinary carbon steel, aluminum, and copper alloys, long, continuous, spiral-shaped or spring-like chips are formed.

[0003] During use, the cutting process generates continuous ribbon-like chips. These long, spiral chips will wrap around the cutting tool. If they are not cleaned in time, they will scratch the machined surface and damage the product's precision and finish. Manual cleaning requires stopping the processing, which seriously slows down production efficiency. Summary of the Invention

The flipping component includes a stop block fixedly connected to the top wall of the cavity inside the tool holder. A baffle is slidably connected inside the rotating rod through a small limiting shaft. A pull rope is fixedly connected to the front of the baffle. A pulling component is installed at the end of the pull rope away from the baffle. The pull rope drives the semi-circular ring to flip by pulling the support arm, causing the shreds to fall off.

[0006] As a preferred embodiment of the CNC turning machine tool of the present invention, the guide assembly includes a first sliding groove, a first rotating groove, a second sliding groove, a second rotating groove and a reset groove formed inside the rotating rod. A one-way valve plate is rotatably connected inside the rotating rod by a torsion spring, and a guide head is fixedly connected inside the tool holder.

[0007] As a preferred embodiment of the CNC turning machine tool of the present invention, the one-way valve plate is provided in two sets, and each set of the one-way valve plate is provided with two one-way valve plates. The front one-way valve plate is provided at the front end of the reset groove and is used to guide the guide head through the first sliding groove and into the first rotating groove. The rear one-way valve plate is provided at the end of the second rotating groove and is used to guide the guide head to slide from the rear end of the reset groove to the front end.

[0008] As a preferred embodiment of the CNC turning machine tool of the present invention, the guide head is composed of a fixed block and a guide head. The guide head is conical and is embedded inside the first sliding groove, the first rotating groove, the second sliding groove, the second rotating groove and the reset groove.

[0009] As a preferred embodiment of the CNC turning machine tool of the present invention, the elastic pushing component further includes a hollow tube fixedly connected to the inside of the guide rod and slidably connected to the inside of the semi-circular ring. A limiting rod is fixedly connected inside the hollow tube and slidably connected to the inside of the slide rod. The slide rod is slidably connected inside the hollow tube. A second spring is provided between the inner wall of the hollow tube and the slide rod.

[0010] As a preferred embodiment of the CNC turning machine tool of the present invention, the double-layer annular strip is composed of two arc-shaped plates. The inner ends of the two arc-shaped plates are connected by a rectangular plate, and the outer end of the inner end is hollow. The outer end of the semi-circular ring is provided with two rectangular openings for the double-layer annular strip to be exposed.

[0011] As a preferred embodiment of the CNC turning machine tool of the present invention, the first spring is arc-shaped and is set on one side of the double-layer annular strip connected by a rectangular plate. A rectangular groove is opened inside the semi-circular ring, the cross section of the rectangular groove corresponds to the cross section of the rectangular block, and the rectangular block is embedded inside the rectangular groove.

[0012] As a preferred embodiment of the CNC turning machine tool of the present invention, the pulling assembly includes a fixed shaft fixedly connected to the inner side of the torsion spring shaft of the support arm, and a fixed plate fixedly connected to the front end of the pulling rope is fixedly connected to the outside of the fixed shaft.

The front of the stop is provided with small limiting shafts evenly distributed, and the end of the rotating rod is provided with a socket, in which the small limiting shafts are embedded.

[0014] As a preferred embodiment of the CNC turning machine tool of the present invention, the fixing plate is disposed on the top of the fixing shaft, and the front end of the pull rope is connected to the fixing shaft by wrapping half a circle around the fixing shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By using the cleaning components and the guide head and the first rotating groove, the rotating rod automatically drives the semi-circular ring to rotate when it moves forward, so that it covers the outside of the tool. This allows the spiral chips to be cleaned while moving. During cleaning, there is no need to stop the machine, thus avoiding the impact on efficiency. At the same time, it can clean in a timely manner to avoid damage to the surface of the workpiece.

[0016] 2. Through the set adaptation component, the double-layer ring bar is rotated by the semi-circular ring. After contact, the double-layer ring bar slides and changes the position of the inclined groove. Then, under the guidance of the guide rod and the elastic force of the second spring, the rectangular block moves inward to fit the tool, thereby cleaning the non-fluffy spiral chips that are attached to the tool surface.

[0017] 3. By using the set flipping component and the blocking of the baffle by the stop block, the semi-circular ring can be automatically flipped after cleaning by pulling the rope, so as to throw off the spiral debris inside the semi-circular ring, thus realizing the self-cleaning debris function of the semi-circular ring.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 Reference Figure 1 - Figure 7This is the first embodiment of the present invention, which provides a CNC turning machine tool that achieves the effect of cleaning the swirling chips wrapped around the tool surface. It includes a cleaning component, comprising a turning machine tool 10 and a tool holder 11 mounted on a tool rack. An electric push rod 12 is fixedly connected to the back of the tool holder 11. A movable plate 13, which is slidably connected to the inside of the tool holder 11, is fixedly connected to the front of the output end of the electric push rod 12. A rotating rod 14, which is rotatably connected to the inside of the tool holder 11 housing, is rotatably connected to the inside of the movable plate 13. Guide components 15 are provided inside both the rotating rod 14 and the tool holder 11. A support arm 16 is rotatably connected to the front of the rotating rod 14 via a torsion spring. A semi-circular ring 17 is fixedly connected to the outer side of the support arm 16. The semi-circular ring 17 cleans the spiral chips through rotational closure and sliding. An adaptation component includes a double-layered annular strip 20 slidably connected inside the semi-circular ring 17. A first spring 21 is provided between the inner end of the double-ringed bar 20 and the inner wall of the semi-circular ring 17. An inclined groove 22 is provided inside the double-ringed bar 20. A guide rod 23 is slidably connected inside the inclined groove 22. An elastic pushing component 24 is provided inside the semi-circular ring 17. The elastic pushing component 24 includes a slide rod 243. A rectangular block 25 is fixedly connected to the outside of the slide rod 243 and slidably connected to the inside of the semi-circular ring 17. After the double-ringed bar 20 is triggered to rotate, it drives the rectangular block 25 to move inward to clean the shreds adhering to the surface of the tool. The flipping component includes a stop block 30 fixedly connected to the top wall of the cavity inside the tool holder 11. A baffle 31 is slidably connected inside the rotating rod 14 through a small limiting shaft. A pull rope 32 is fixedly connected to the front of the baffle 31. A pulling component 33 is provided at the end of the pull rope 32 away from the baffle 31. The pull rope 32 drives the semi-circular ring 17 to flip by pulling the support arm 16, causing the shreds to fall off.

[0023] Specifically, the cleaning components can promptly clean the spiral shavings on the tool surface during tool switching. After tool switching, the electric push rod 12 is driven to move the moving plate 13. After the moving plate 13 moves, the rotating rod 14 will start to move forward. The rotating rod 14 will push the support arm 16 to move. Guided by the first rotating groove 152 and the guide head 157, the rotating rod 14 can drive the semi-circular ring 17 to rotate and lock onto the outside of the tool. As the closed semi-circular ring 17 moves forward, the spiral shavings can be pushed off the tool surface and fall off under the push of the semi-circular ring 17.

[0024] With the adaptive components, the rectangular block 25 can move inward while the semicircular ring 17 is closed, thereby pushing away the loose spiral chips that are attached to the tool. When the semicircular rings 17 are close to each other, the two double-layer ring strips 20 will move closer to each other and slide under pressure. This will change the position of the inclined groove 22, and then, guided by the guide rod 23, the hollow tube 241 will move inward. At this time, the slide rod 243 will push the rectangular block 25 inward to fit the surface of the tool. Since the rectangular block 25 is rectangular and long, it can be offset from the groove on the surface of the tool and will not get stuck. With the elasticity of the second spring 244, it can adaptively adjust according to the thickness of the tool.

[0025] The rotating component allows the semicircular ring 17 to quickly rotate after the spiral shavings are pushed out of the cutter, thus dislodging the attached spiral shavings. When the semicircular ring 17 rotates inward during its closed rotation, the support arm 16, connected by a torsion spring shaft, can rotate to the front. During the forward movement of the rotating rod 14, when the baffle 31 contacts the stop block 30, the rotating rod 14 will still move forward a short distance. At this time, the semicircular ring 17 rotates to its reset position. As the rotating rod 14 moves forward, the baffle 31 is blocked by the stop block 30, which causes the pull rope 32 to pull the fixed plate 332, thereby causing the fixed shaft 331 to rotate. This causes the support arm 16 to drive the semicircular ring 17 to rotate quickly, dislodging the spiral shavings. When the rotating rod 14 resets, the reset of the torsion spring shaft will pull the pull rope 32 forward again, causing the baffle 31 to reset.

[0026] Furthermore, the guide assembly 15 includes a first sliding groove 151, a first rotating groove 152, a second sliding groove 153, a second rotating groove 154 and a reset groove 155 formed inside the rotating rod 14. A one-way valve plate 156 is rotatably connected inside the rotating rod 14 via a torsion spring, and a guide head 157 is fixedly connected inside the tool holder 11.

[0027] In its initial state, the semicircular ring 17 is positioned behind the protrusion at the front of the tool. As the rotating rod 14 moves forward, the guide head 157 first slides inside the first sliding groove 151, moving the semicircular ring 17 forward. When the guide head 157 reaches the end of the first sliding groove 151, the semicircular ring 17 is positioned in front of the protrusion at the front of the tool. As the rotating rod 14 continues to move forward, the guide head 157 enters the first rotating groove 152. Through limiting guidance, the semicircular ring 17 can rotate 90 degrees towards each other until it closes during its forward movement. After closing, the guide head 157 is positioned at the initial end of the second sliding groove 153. As the rotating rod 14 moves forward, the guide head 157 will... The semicircular ring 17 slides inside the second sliding groove 153 until it reaches the end. At this position, the semicircular ring 17 has pushed the spiral chips away from the tool. Simultaneously, the semicircular ring 17 leaves the tool, and then the guide head 157 enters the second rotating groove 154. During this movement, the rotating rod 14 rotates outward 90 degrees to reset. Then, the guide head 157 enters the reset groove 155. At this time, the stop block 30 and the baffle 31 are in contact. The rotating rod 14 can still move forward. When moving forward, the guide head 157 will slide a small distance at the end of the reset groove 155. At this time, the rotating rod 14 moves forward, while the baffle 31 remains in place, thereby causing the pull rope 32 to pull the semicircular ring 17 to rotate quickly.

[0028] Preferably, two sets of one-way valve plates 156 are provided, with two one-way valve plates 156 in each set. The front one-way valve plate 156 is located at the front end of the reset groove 155 and is used to guide the guide head 157 through the first sliding groove 151 into the first rotating groove 152. The rear one-way valve plate 156 is located at the end of the second rotating groove 154 and is used to guide the guide head 157 to slide from the rear end of the reset groove 155 to the front end. The guide head 157 is composed of a fixed block and a guide head. The guide head is conical and is embedded inside the first sliding groove 151, the first rotating groove 152, the second sliding groove 153, the second rotating groove 154 and the reset groove 155.

[0029] It should be noted that the one-way valve plate 156 is a one-way structure. In its initial state, it can only rotate counterclockwise and cannot rotate clockwise. When the front one-way valve plate 156 guides the guide head 157, it can allow it to directly enter the first rotating groove 152 from the first sliding groove 151 without entering the interior of the reset groove 155. When the rear one-way valve plate 156 guides the guide head 157, it can allow it to slide from the end of the reset groove 155 to the front end without entering the interior of the second rotating groove 154, thereby keeping the semicircular ring 17 in its initial state for reset.

[0030] During use, when the tool is cutting the workpiece, after tool switching, the spiral chips are wrapped around the tool. At this time, the tool that has completed the switching action can be directly cleaned. The electric push rod 12 is driven, causing its output end to push the moving plate 13 to move inside the tool holder 11. As the moving plate 13 moves, it pushes the rotating rod 14, which in turn pushes the support arm 16, causing the semi-circular ring 17 to move forward. The guide head 157 slides inside the first sliding groove 151. When the guide head 157 slides to the end of the first sliding groove 151, the semi-circular ring 17 moves to the tool cleaning starting position. Limited by the one-way valve plate 156, the moving rotating rod 14 causes the guide head 157 to enter the first rotating groove 152, thus... The rotating rod 14 moves and rotates inward, causing the semicircular rings 17 to move closer together. When the guide head 157 completes its stroke inside the first rotating groove 152 and enters the second sliding groove 153, the two semicircular rings 17 close and cover the outside of the tool. With the push of the output end of the electric push rod 12, the rotated rotating rod 14 moves forward, and the guide head 157 slides inside the second sliding groove 153. This causes the merged semicircular rings 17 to move forward and push the spiral chips out of the tool. When the guide head 157 enters the second rotating groove 154, the rotating rotating rod 14 resets, thereby resetting the semicircular rings 17. Then, the guide head 157 enters the reset groove 155 and slides inside the reset groove 155, resetting the semicircular rings 17 to their initial position.

[0031] In summary, by guiding the first rotating groove 152 and the second sliding groove 153 through the guide head 157, the rotating rod 14 can drive the semi-circular ring 17 to rotate automatically when moving, covering the outside of the tool, and thus, under the push, the spiral chips on the outside of the tool can be pushed off and cleaned in time.

[0032] Example 2 Reference Figure 8 - Figure 9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an adaptation component for a CNC turning machine tool, which solves the problem that the spiral chips that are not fluffy enough to adhere to the tool surface are not easy to be pushed off. It includes an elastic pushing component 24 and a hollow tube 241 fixedly connected to the inside of the guide rod 23 and slidably connected to the inside of the semi-circular ring 17. A limiting rod 242 is fixedly connected to the inside of the hollow tube 241 and slidably connected to the inside of the slide rod 243. The slide rod 243 is slidably connected to the inside of the hollow tube 241. A second spring 244 is provided between the inner wall of the hollow tube 241 and the slide rod 243.

[0033] Specifically, since the slide bar 243 slides inside the hollow tube 241 and is supported by the second spring 244, when the rectangular block 25 moves, if the diameter of the tool is large, the second spring 244 can be compressed, thereby adapting to the thickness of the tool for adaptive fitting.

[0034] Furthermore, the double-layer annular strip 20 is composed of two arc-shaped plates. The inner ends of the two arc-shaped plates are connected by a rectangular plate. The outer end of the inner end is hollow. The outer end of the semicircular ring 17 has two rectangular openings for the double-layer annular strip 20 to be exposed. The first spring 21 is arc-shaped and is set on the side of the double-layer annular strip 20 connected by the rectangular plate. The interior of the semicircular ring 17 has a rectangular groove. The cross-section of the rectangular groove corresponds to the cross-section of the rectangular block 25. The rectangular block 25 is embedded inside the rectangular groove.

[0035] The hollow area inside the double-layer annular bar 20 is used to accommodate the hollow tube 241 and the limiting rod 242, while the exposed part of the structure at the outer end is used for contact triggering. When the semicircular ring 17 rotates and closes, the two double-layer annular bars 20 will stick to each other and push themselves into the corresponding semicircular ring 17. The arc-shaped first spring 21 can adapt to the structure of the semicircular ring 17, so that it provides a thrust for the reset of the double-layer annular bar 20.

[0036] During use, as the semicircular ring 17 rotates inward to close, the two independent double-layered annular bars 20 begin to approach each other. When the double-layered annular bars 20 come into contact, they begin to slide inward due to the pushing force of the closing semicircular ring 17. As the double-layered annular bars 20 slide, they compress the first spring 21 and simultaneously change the position of the inclined groove 22. The inclined groove 22 then guides the guide rod 23, causing the hollow tube 241 to move inward. Supported by the second spring 244, the sliding rod 243 follows the hollow tube 241 inward, thereby exposing the rectangular block 25. The rectangular block 25 can fit against the surface of the tool, and due to its rectangular structure, it does not... There may be jamming or resistance. If the tool is too thick, when the rectangular block 25 contacts the tool surface, it will compress the second spring 244 through the slide bar 243, so that the rectangular block 25 can adapt to the thickness of the tool. When the semicircular ring 17 is closed, the rectangular block 25 is attached to the tool surface and moves forward with the semicircular ring 17. When the rectangular block 25 moves forward, it will push the non-fluffy spiral chips attached to the tool surface away from the tool. When the semicircular ring 17 rotates outward, the first spring 21 will release pressure, thereby pushing the double-layer ring bar 20 to reset. At this time, the second spring 244 will also release its elasticity. After the inclined groove 22 is reset, the rectangular block 25 will retract into the interior of the semicircular ring 17 again to prevent the chips from wrapping around the outside of the rectangular block 25.

[0037] In summary, by changing the position of the inclined groove 22 through the close proximity of the double-layered annular bars 20, the rectangular block 25, under the guidance and in conjunction with the elastic force of the second spring 244, can adaptively conform to the tool surface and push the non-fluffy spiral chips that conform to the tool away from the tool.

[0038] Example 3 Reference Figure 10 - Figure 13 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a flipping component for a CNC turning machine tool, which solves the problem of shavings adhering to the surface of the semi-circular ring 17 after cleaning. It includes a pulling component 33, which includes a fixed shaft 331 fixedly connected to the inner side of the torsion spring shaft of the support arm 16. A fixed plate 332 fixedly connected to the front end of the pull rope 32 is fixedly connected to the outside of the fixed shaft 331. The top of the moving plate 13 has a notch, and the size of the notch corresponds to the size of the stop block 30. The front of the stop plate 31 is provided with evenly distributed small limiting shafts, and the end of the rotating rod 14 has an insertion hole. The small limiting shafts are embedded in the rectangular insertion hole.

[0039] Specifically, since the fixed shaft 331 is fixed outside the torsion spring shaft of the support arm 16, when the fixed plate 332 drives the fixed shaft 331 to rotate, it will pull the torsion spring shaft to rotate, causing the support arm 16 to flip. Since the top of the moving plate 13 has a notch, when the moving plate 13 is pushed forward, it will pass directly through the notch without being blocked, so that the rear baffle 31 can normally contact the stop block 30. Since the baffle 31 is limited by a small limiting shaft inserted into the rotating rod 14, when the stop block 30 abuts against the top of the baffle 31, the baffle 31 can also stop moving normally without warping.

[0040] Furthermore, the fixing plate 332 is set on the top of the fixing shaft 331, and the front end of the pull rope 32 is connected to the fixing shaft 331 by wrapping half a circle around the fixing shaft 331.

[0041] When the baffle 31 stops moving, the rotating rod 14 moves forward, causing the fixed plate 332 to rotate forward. Then, under the pull of the rope 32, the support arm 16 drives the semi-circular ring 17 to rotate rapidly.

[0042] In use, after the guide head 157 enters the second rotating groove 154, the rotating rod 14 will rotate and reset. At this time, the semi-circular ring 17 will reset to its initial state. When the semi-circular ring 17 resets to its initial state, the guide head 157 has already entered the reset groove 155. The rotating rod 14 will continue to move forward, causing the guide head 157 to slide at the end of the reset groove 155 until it reaches the very end. When the guide head 157 enters the reset groove 155, the stop block 30 is already in contact with the baffle 31. Therefore, after the rotating rod 14 moves forward, the baffle 31 will stop moving forward, and the rotating rod 14 will move forward alone. At this time, the fixed plate 332 will be subjected to... The tension of the pull rope 32 causes the fixed shaft 331 to rotate. The fixed shaft 331 causes the torsion spring shaft of the support arm 16 to rotate, which in turn causes the semi-circular ring 17 to flip rapidly through the support arm 16, throwing off the spiral debris inside the semi-circular ring 17. When the semi-circular ring 17 is flipped and cleaned, the electric push rod 12 can drive the moving plate 13 to reset. At this time, the guide head 157 will slide inside the reset groove 155 until it slides to the front end of the first sliding groove 151. During the reset, the support arm 16 is affected by the torsion spring shaft and will automatically drive the semi-circular ring 17 to reset. At the same time, the pull rope 32 will pull the baffle 31 to the position where it is in contact with the end of the rotating rod 14, waiting for the second trigger.

[0043] In summary, by limiting the position of the stop block 30 and the baffle plate 31, the pull rope 32 can pull the fixed plate 332, thereby causing the semi-circular ring 17 to quickly flip after rotating and resetting, thus throwing off the internal spiral debris.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
