Description

Technical Field

[0001] This application relates to the technical field of tool holders for CNC lathes, and in particular to a stepped tool holder for a CNC lathe with a tool holder. Background Technology

[0002] The stepped tool post allows multiple machining processes to share parts set on multiple tool positions on the same tool post. This not only reduces tool change time and improves machining efficiency, but also adapts to changing machining needs, making it possible to achieve efficient machining of complex parts on CNC lathes.

[0003] For example, patent application number 2025110185661 discloses a dual-spindle docking tool rack structure for a CNC lathe, including a mounting base with a tool rack, a tool holder with an adjustment component detachably connected to the tool rack, and an elastic washer fitted on the fastener; by slidingly engaging the bottom protrusion of the fastener with the groove of the tool rack, the tool holder can be finely adjusted after pre-tightening and compressing the elastic washer; then, the adjustment component is pressed to make its longitudinal displacement, and after being limited by the limiting component, the adjustment component is rotated to realize the fine adjustment of the tool holder.

[0004] The aforementioned existing technology can be used to fine-tune the tool holder, but the following problems still exist in subsequent use: metal chips generated during cutting adhere to the tool or fall directly onto the tool holder. If not cleaned in time, the metal chips will interfere with the normal cutting path of the tool and affect the surface finish of the machined surface. Relying on manual cleaning at regular intervals not only increases the risk of collision between the operator and the tool, but also reduces the continuous processing efficiency of the equipment.

[0005] The aforementioned problems are not limited to ordinary tool holder structures. As a common form of tool holder, stepped tool holders have tool holders distributed in a stepped manner, with smaller gaps between each layer of tool holders, resulting in a more compact structure. Metal shavings are more likely to accumulate at the tool holders, making cleaning more difficult. Summary of the Invention

[0006] To address the technical problem of the aforementioned reliance on manual cleaning of metal chips from stepped tool holders, which is dangerous, this application provides a stepped tool holder for a CNC lathe with a tool holder, employing the following technical solution: A stepped tool holder for a CNC lathe includes a tool holder that is slidably mounted on the lathe guide rail and has a stepped structure. Each horizontal plane of the tool holder has multiple mounting holes for mounting tools, and the vertical plane of the tool holder has fastening bolts for fixing the tools.

[0007] The tool holder is equipped with a cleaning ring that can move up and down, which is used to clean filamentous metal shavings from the tools.

[0008] The bottom of the tool holder is equipped with a collection groove, and a transition groove communicating with the collection groove is opened at the inside corner of the stepped structure of the tool holder.

[0009] Each horizontal plane of the tool holder is equipped with actuating claws that are staggered with the mounting holes. The actuating claws are used to push metal chips into the transition groove.

[0010] A collection plate is slidably installed in the collection tank. When the collection plate moves, it can sequentially drive the cleaning ring to rise and clean the cutting tool, drive the toggle claw to move and push the metal chips to the transition tank, and push the metal chips in the collection tank to the outlet when resetting.

[0011] Preferably, the cleaning ring has a frustum-shaped structure with an annular flexible pad inside.

[0012] The blade holder is equipped with a lifting rod that is connected to the cleaning ring. The bottom of the lifting rod is connected to a lifting frame via a lifting connecting rod. A cylindrical block is mounted on the lifting frame.

[0013] The collection plate is equipped with an inclined guide plate. When the collection plate moves, the lifting frame is driven to rise through the cooperation of the guide plate and the cylindrical block.

[0014] Preferably, the guide plate is mounted on the collecting plate via a spring hinge, and the collecting plate is provided with a limit block for restricting the unidirectional rotation of the guide plate.

[0015] When the collecting plate moves forward, the limiting block prevents the guide plate from rotating, and the guide plate pushes the cylindrical block upward.

[0016] When the collecting plate is reset, the guide plate is pushed and rotated relative to the first cylindrical block to avoid and pass over the first cylindrical block.

[0017] Preferably, the bottom of the actuating claw is connected to a linkage rod, the end of the linkage rod is equipped with a linkage connecting rod, and a cylindrical block is provided on the linkage connecting rod.

[0018] The collecting plate is equipped with a linkage block. When the collecting plate moves, the linkage block and the second cylindrical block drive the linkage rod to move, thereby causing the toggle claw to move horizontally.

[0019] Preferably, the top of the actuating claw is an inverted L-shaped structure, and the L-shaped end is symmetrically mounted with an actuating rod via a spring hinge. The actuating rod is provided with a downwardly inclined conical protrusion.

[0020] When the actuating claw moves horizontally, the actuating rod scrapes off the metal shavings and pushes them into the transition groove. The conical protrusion is used to prevent filamentous metal shavings from crossing the actuating rod.

[0021] Preferably, the transition groove is provided with multiple pull rods, and the top of the pull rods is equipped with a stop rod via a spring hinge.

[0022] The bottom of the pull rod is connected to a pull rod that extends into the relief cavity. The end of the pull rod is equipped with a pull frame, and the pull frame is provided with a cylindrical block.

[0023] When the collecting plate moves, the guide plate and the cylindrical block three drive the pull rod to rise, so that the blocking rod is inserted into the filamentous metal shavings. When the pull rod descends, it drives the filamentous metal shavings to fall into the transition groove.

[0024] Preferably, a guide frame is also installed in the transition groove, and a through groove is opened on the guide frame for the pull rod to pass through.

[0025] When the pull rod moves the stop bar through the through slot, the guide frame forces the stop bar to rotate and retract.

[0026] As the pull rod descends, the guide frame intercepts filamentous metal shavings, causing them to fall into the collection tank.

[0027] Preferably, it also includes a rotating shaft disposed on the side of the collection trough away from its outlet, a winding wheel mounted on the rotating shaft, and a traction rope wound around the winding wheel, with the end of the traction rope away from the winding wheel connected to the collection plate.

[0028] A sealing plate is installed at the outlet of the collection tank, and an elastic telescopic rod connects the sealing plate and the collection plate.

[0029] Preferably, the rotating shaft is driven by a drive motor to rotate forward or in reverse.

[0030] When the rotating shaft rotates clockwise, the traction rope is wound up by the winding wheel, causing the collecting plate to move away from the outlet.

[0031] When the rotating shaft reverses, the traction rope is released, the elastic telescopic rod resets, and the collecting plate moves towards the outlet, pushing the metal shavings in the collecting tank towards the outlet.

[0032] Preferably, the upward movement of the cleaning ring, the lateral pushing movement of the agitator, and the downward movement of the pull rod are all performed by a single stroke of the collecting plate, so that the tool cleaning, metal chip collection, and filamentous metal chip pulling are completed in sequence.

[0033] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention features a cleaning ring on the tool holder that mates with the mounting holes and can move up and down. Combined with its frustum-shaped inclined structure, this allows filamentous metal chips adhering to the cutting tool to be directly scraped off after cutting and prevents them from re-adhering. Simultaneously, the annular flexible pad inside the cleaning ring adapts to the surface shape of different types of tools, ensuring that metal chips on complex contours such as irregularly shaped tools can also be effectively removed. This solves the problems of incomplete manual cleaning and easy residue buildup, and avoids metal chips interfering with subsequent cutting paths and affecting the surface finish of the machined material.

[0034] 2. This invention features actuating claws arranged in a staggered pattern with mounting holes on each horizontal plane of the tool holder, and a collection groove and a transition groove are configured inside the tool holder. When the cleaning ring scrapes metal shavings onto the surface of the tool holder, the actuating claws, through their L-shaped ends and elastically mounted actuating rods, push the filamentous metal shavings and debris into the transition groove and then into the collection groove. The conical protrusions on the actuating rods prevent the filamentous metal shavings from passing over the actuating rods during the pushing process, while the elastic avoidance design of the actuating rods prevents collisions with the cutting tools. This achieves automatic cleaning and collection of metal shavings within a compact space without manual intervention.

[0035] 3. The present invention further includes a collection plate in the collection tank, and through the cooperation of the guide plate with cylindrical blocks one, two, and three, it realizes the linkage action of the cleaning ring rising to clean, the toggle claw moving to push, and the pull rod pulling down the filamentous metal chips. In particular, for the problem that larger filamentous metal chips are difficult to fall directly, the pull rod, together with the blocking rod, inserts and pulls them into the transition tank, and then they fall into the collection tank after being intercepted by the guide frame. Finally, the waste chips are pushed to the outlet by the reset of the collection plate. The entire cleaning, collection, and discharge process is completed automatically without the need for operators to touch the cutting tools, which improves the continuous processing efficiency and operational safety of the equipment.

[0053] The following is in conjunction with the appendix Figures 1 to 16 This application will be described in further detail.

[0054] This application discloses a stepped tool holder for a CNC lathe with a swivel tool, which solves the problems of incomplete manual cleaning, dangerous process, and easy residue, and avoids the problem of metal chips interfering with subsequent cutting paths and affecting the surface finish of the machined surface.

[0055] A stepped tool holder for a CNC lathe includes a tool holder 1 that is slidably mounted on the lathe guide rail and has a stepped structure. Multiple mounting holes 2 for mounting tools are evenly provided on each horizontal plane of the tool holder 1 along its width direction. Multiple fastening bolts 3, which correspond one-to-one with the mounting holes 2, are provided on the vertical surface of the tool holder 1 for fixing the tools.

[0056] Before starting the cutting operation, place the tool inside the mounting hole 2 and then fix it in place with the fastening bolt 3.

[0057] The tool holder 1 is provided with a cleaning ring 4 that can move up and down and fits the mounting holes 2, which is used to clean the filamentous metal shavings on the tool. The bottom inside the tool holder 1 is provided with a collection groove 11 for collecting waste shavings, and the outlet of the collection groove 11 is located in the lower step section. The outlet of the collection groove 11 is sealed with a sealing plate 12. A transition groove 13 that is connected to the collection groove 11 is opened at the inside corner of the stepped structure of the tool holder 1. Each horizontal plane of the tool holder 1 is provided with a toggle claw 5 that is staggered with the mounting holes 2 and is used to send the filamentous metal shavings into the transition groove 13.

[0058] It should be noted that the lathe guide rail is existing technology. Multiple T-slots are evenly provided on the lathe guide rail along its width direction. The tool holder 1 is slidably mounted on the lathe guide rail by a T-shaped protrusion that cooperates with the T-slot.

[0059] In actual operation, after the cutting is completed, the metal chips are removed from the tool by the cleaning ring 4. The cleaning ring 4 is provided with a frustum-shaped structure. The inclined surface of the frustum-shaped structure makes the metal chips not adhere to the cleaning ring 4 and fall directly onto the tool holder 1. At this time, by moving the actuating claw 5, the metal chips on the tool holder 1 are pushed towards the transition groove 13. The metal chips fall into the collection groove 11 through the transition groove 13.

[0060] The above steps can then be used to clean the cutting tool and the tool holder 1 after cutting.

[0061] To facilitate timely collection and processing of metal shavings, a collection plate 15 is slidably installed inside the collection tank 11. A rotating shaft 16 is mounted on the side of the collection tank 11 away from its outlet via a bearing. A winding wheel 17 is mounted on the rotating shaft 16, and a traction rope 18 is wound on the winding wheel 17. The end of the traction rope 18 away from the winding wheel 17 is mounted on the collection plate 15. An elastic telescopic rod 19 is mounted on the sealing plate 12, and the telescopic end of the elastic telescopic rod 19 is mounted on the collection plate 15 for resetting the sealing plate 12.

[0062] The top of the collection trough 11 is provided with a guide slope to increase the collection area of ​​the collection trough 11. In specific operation, the output shaft of the drive motor (not shown in the figure) installed in the collection trough 11 drives the rotating shaft 16 to rotate. During the rotation of the rotating shaft 16, the winding wheel 17 winds up the traction rope 18. During the winding process, the traction rope 18 drives the collection plate 15 to move away from the outlet of the collection trough 11. At this time, the elastic telescopic rod 19 is stretched.

[0063] When the collecting plate 15 moves away from the outlet of the collecting trough 11, the guide plate 43 and the cylindrical block 46 cooperate with each other to drive the cleaning ring 4 upward through the lifting rod 41. Specifically, the inside side of the knife rack 1 is provided with a relief cavity 10. The inside of the knife rack 1 is also provided with a lifting rod 41 that moves up and down and corresponds to the cleaning ring 4. The cleaning ring 4 is installed at the top of the corresponding lifting rod 41. The bottom of the lifting rod 41 corresponding to each step is jointly installed with a lifting connecting rod 42. The lifting connecting rod 42 and the collecting plate 15 extend into the relief cavity 10. The collecting plate 15 is provided with a guide plate 43 that is inclined and located inside the relief cavity 10 through a spring hinge. The hinge of the collecting plate 15 is provided with a limiting block 44 for limiting the guide plate 43. The end of the lifting connecting rod 42 located inside the relief cavity 10 is jointly installed with a lifting frame 45. The lifting frame 45 is provided with a cylindrical block 46 that cooperates with the guide plate 43.

[0064] The cleaning ring 4 has an annular flexible pad 47 inside.

[0065] In actual operation, during the movement of the collecting plate 15, the collecting plate 15 synchronously drives the guide plate 43 to move synchronously. The guide plate 43 first abuts against the cylindrical block 46. Due to the obstruction of the limiting block 44, the cylindrical block 46 moves along the guide plate 43. At this time, the cylindrical block 46 drives the lifting frame 45 to move upward. During the upward movement of the lifting frame 45, the lifting rod 41 is driven to move upward synchronously through the lifting linkage 42. During the upward movement of the lifting rod 41, the cleaning ring 4 moves upward, which can clean the metal chips on the surface of the tool. The annular flexible pad 47 can adapt to different types of tools (such as irregularly shaped tools) to ensure that the metal chips on the tool surface are cleaned more thoroughly.

[0066] It should be noted that during the movement of the collecting plate 15 away from the outlet of the collecting trough 11, when the front of the guide plate 43 contacts the cylindrical block 46, the limiting block 44 can limit the guide plate 43, so that the guide plate 43 will not rotate around the spring hinge when it contacts the cylindrical block 46. When the collecting plate 15 is reset, when the back of the guide plate 43 contacts the cylindrical block 46, the cylindrical block 46 will obstruct the movement of the guide plate 43. At this time, the guide plate 43 will rotate around the spring hinge until the guide plate 43 rotates to be parallel to the bottom of the cylindrical block 46. At this time, the guide plate 43 can pass over the cylindrical block 46 in a horizontal posture. After the guide plate 43 has completely passed over the cylindrical block 46, the spring hinge will drive the guide plate 43 to reset.

[0067] After the metal shavings on the cutting tool fall onto the tool holder 1, the collecting plate 15 continues to move. The collecting plate 15, through the guide plate 43 and the cylindrical block 2, can drive the actuating claw 5 to collect the metal shavings that have fallen onto the tool holder 1. Specifically, a second relief cavity 101 is provided on the side of the tool holder 1 away from the first relief cavity 10. The bottom of the actuating claw 5 corresponding to each step is equipped with a linkage rod 51 that moves inside the tool holder 1. The collecting plate 15 and the linkage rod 51 extend into the second relief cavity 101. A linkage link 52 is installed on the end of the linkage rod 51 located inside the second relief cavity 101. A linkage block 53 is installed on the top side of the collecting plate 15 located inside the second relief cavity 101. A cylindrical block 2 54 that cooperates with the linkage block 53 is installed on the linkage link 52.

[0068] The top of the toggle pawl 5 is set as an inverted L-shaped structure. The L-segment of the toggle pawl 5 is symmetrically mounted with a toggle lever 55 along its width direction via a spring hinge. The toggle lever 55 is provided with a downwardly inclined conical protrusion 56.

[0069] The tool holder 1 is equipped with a telescopic spring (not shown in the figure) for resetting the linkage rod 52. During operation, after the collecting plate 15 passes the first cylindrical block 46, it causes the linkage block 53 to contact the second cylindrical block. At this time, the linkage block 53 drives the linkage rod 52 to move via the second cylindrical block. During the movement of the linkage rod 52, it drives the actuating pawl 5 to move synchronously via the linkage rod 51. When the horizontal end of the actuating pawl 5 contacts the inside corner of the stepped structure of the tool holder 1, the actuating pawl 5 moves via the actuating rod 51. 5 can push the metal shavings on the blade holder 1 into the transition groove 13. The actuating rod 55 pushes the filamentous metal shavings to make slight contact with the inside corner of the stepped structure of the blade holder 1 without excessive compression. During this process, the actuating rod 55 can scrape the broken metal shavings on the blade holder 1 into the transition groove 13. The actuating rod 55 can also push the filamentous metal shavings into the transition groove 13. During this process, the conical protrusion 56 can limit the filamentous metal shavings to prevent them from passing over the actuating rod 55 during the pushing process.

[0070] The top of the actuating claw 5 is set as an inverted L-shaped structure. The horizontal section of the actuating claw 5 can compensate for the width of the transition groove 13, ensuring that the actuating rod 55 can completely push the metal chips into the transition groove 13 while avoiding the vertical section of the actuating claw 5 from entering the transition groove 13 and causing interference. The actuating rod 55 is mounted on the actuating claw 5 by a spring, ensuring that the actuating rod 55 can smoothly avoid and pass over the tool, and preventing the actuating rod 55 from colliding with the tool.

[0071] When the actuating claw 5 cleans the metal shavings on the knife holder 1, the actuating rod 55 can push the powdered metal through the transition groove 13 into the collection groove 11. The collection plate 15, through the guide plate 43 and the cylindrical block 137, can drive the pull rod 131 to move upward, so that the blocking rod 132 is inserted into the filamentous metal shavings. During the downward movement of the pull rod 131, the blocking rod 132 can pull the filamentous metal shavings downward into the transition groove 13. Specifically, multiple pull rods 131 are evenly arranged along the length of the transition groove 13. The top of the pull rod 131 is equipped with a blocking rod 132 through a spring hinge. The transition groove 13 is also equipped with a guide frame 133, and the guide frame 133 is provided with a through groove 134 for the pull rod 131 to make way.

[0072] A pull rod 135 is installed at the bottom of the pull rod 131, and the pull rod 135 extends into the relief cavity 10. A pull frame 136 is installed at one end of the pull rod 135 inside the relief cavity 10. A cylindrical block 137 that cooperates with the guide plate 43 is installed on the pull frame 136.

[0073] In specific operation, during the movement of the linkage 52, the collecting plate 15 synchronously drives the guide plate 43 to contact the cylindrical block 137. At this time, the cylindrical block 137 moves upward along the guide plate 43. During the upward movement of the cylindrical block 137, the pull-out linkage 135 is driven upward through the pull-out linkage 136. During the upward movement of the pull-out linkage 135, the pull-out rod 131 is driven upward. During the upward movement of the pull-out rod 131, the blocking rod 132 is driven upward and passes through the through groove 134.

[0074] Since some of the filamentous metal scraps may not fall into the transition groove 13, when the actuating rod 55 drives the filamentous metal scraps into the upper part of the transition groove 13, the pull rod 131 just drives the blocking rod 132 to insert into the filamentous metal scraps. At this time, the cylindrical block 3 137 just passes the guide plate 43 and moves down due to gravity. Due to the influence of gravity, the pull rod 131 drives the filamentous metal scraps down through the blocking rod 132.

[0075] It should be noted that when the pull rod 131 drives the blocking rod 132 through the through groove 134, the blocking rod 132 rotates downward around the corresponding spring hinge and automatically retracts under the obstruction of the guide frame 133, so that the blocking rod 132 can pass smoothly through the through groove 134 and avoid jamming or interference.

[0076] As the pull rod 131 continues to move downward, driving the blocking rod 132 into the area where the filamentous metal scraps accumulate, the blocking rod 132 can effectively limit the filamentous metal scraps during the downward movement of the pull rod 131, preventing them from loosening and falling off, thereby ensuring that the filamentous metal scraps can be stably guided and smoothly enter the interior of the transition groove 13.

[0077] When the pull rod 131 continues to move downward and drives the blocking rod 132 to pass through the through groove 134 again, the guide frame 133 blocks the blocking rod 132, so that the filamentous metal shavings are intercepted and left on the guide frame 133. Under the inclined guiding action of the guide frame 133, the filamentous metal shavings fall into the collection groove 11 through the transition groove 13 due to gravity, while the pull rod 131 drives the blocking rod 132 to continue to pass through the through groove 134. During this process, due to the continuous blocking action of the guide frame 133, the blocking rod 132 rotates upward around the spring hinge to reset, thereby ensuring that the pull rod 131 can drive the blocking rod 132 to pass through the through groove 134 smoothly.

[0078] After the metal shavings have completely fallen into the collection tank 11, the output shaft of the drive motor drives the rotating shaft 16 to reverse and release the traction rope 18. At this time, the elastic telescopic rod 19 resets and drives the collection plate 15 to reset. During the reset process of the collection plate 15, the metal shavings collected inside the collection tank 11 are moved to the outlet of the collection tank 11. After the collection plate 15 is reset, the sealing plate 12 is removed and the collection plate 15 is driven outward by the elastic telescopic rod 19 until the collection plate 15 pushes the metal shavings to the outlet of the collection tank 11 for unified collection and processing. Thus, the metal shavings are cleaned and collected without human intervention.

[0079] Working principle: The tool holder adopts a stepped structure design, with multiple mounting holes 2 evenly opened on each horizontal plane. The tool is fixed by the corresponding fastening bolts 3 on the vertical plane. During operation, the tool is inserted into the mounting hole 2 and the bolt is tightened to complete the clamping. The bottom of the tool holder 1 is provided with a collection groove 11, the outlet of which is located in the lower step section and is sealed by a sealing plate 12. The transition groove 13 opened at the inside corner of the stepped structure connects each horizontal plane with the collection groove 11. At the same time, each horizontal plane is also provided with a moving claw 5 that is staggered with the mounting hole 2. This structural layout allows the entire tool holder 1 to slide on the lathe guide rail, providing a stable platform for subsequent cutting and cleaning work.

[0080] After cutting, the cleaning ring 4, which can move up and down, is the first to perform the operation. The cleaning ring 4 has a frustum-shaped inclined structure, which can effectively prevent metal chips from adhering. When the cleaning ring 4 moves, it scrapes the filamentous metal chips on the tool directly onto the surface of the tool holder 1. Then, the actuating claw 5 starts to work. Its L-shaped structure at the top, together with the actuating rod 55 installed by the spring hinge, pushes the metal chips on the tool holder 1 towards the transition groove 13. The conical protrusion 56 on the actuating rod 55 can limit the filamentous metal chips and prevent them from passing the actuating rod 55. At the same time, the elastic installation method of the actuating rod 55 can avoid the tool, ensuring that the metal chips are completely pushed into the transition groove 13 and finally fall into the collection groove 11.

[0081] The collection trough 11 is equipped with a sliding collection plate 15. The drive motor drives the rotating shaft 16 and the winding wheel 17 to wind the traction rope 18, causing the collection plate 15 to move away from the outlet. When the collection plate 15 moves, the guide plate 43 and the cylindrical block 46 work together to drive the lifting frame 45 to move upward. Then, the lifting rod 41 drives the cleaning ring 4 to rise and clean the surface of the tool. The annular flexible pad 47 inside the cleaning ring 4 can adapt to different types of tools. When the collection plate 15 continues to move, the linkage block 53 drives the linkage rod 51 and the actuating claw 5 to move through the cylindrical block 2, completing the pushing of metal chips. When the collection plate 15 is reset, the spring hinge and the limit block 44 ensure that the guide plate 43 can smoothly pass through each cylindrical block and return to its original position.

[0082] For larger filamentous metal shavings, the transition groove 13 is equipped with a pull rod 131 and a blocking rod 132. When the collecting plate 15 moves, the guide plate 43 and the cylindrical block 137 work together to drive the pull rod 131 upward, so that the blocking rod 132 is inserted into the filamentous metal shavings. Then the pull rod 131 moves downward to pull the filamentous metal shavings into the transition groove 13. The through groove 134 on the guide frame 133 causes the blocking rod 132 to automatically rotate and retract when passing through, avoiding jamming. When the pull rod 131 moves downward again, the blocking effect of the guide frame 133 intercepts the filamentous metal shavings and guides them to fall into the collecting groove 11. After cleaning, the drive motor reverses to release the traction rope 18, and the elastic telescopic rod 19 pushes the collecting plate 15 to reset and pushes the metal shavings in the collecting groove 11 to the outlet. The sealing plate 12 can then be removed for unified collection and processing.
