Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to an energy-saving slant CNC machine tool chip removal device and method. Background Technology

[0002] A slant bed CNC machine tool is a type of CNC lathe with a slant bed structure. Its guide rail plane forms a certain angle with the ground plane. This design increases the cross-sectional area to improve bending and torsional rigidity, and utilizes the characteristic that the cutting force is aligned with the direction of gravity to reduce vibration, thereby improving machining accuracy and stability. Its spindle unit uses high-speed angular contact bearings, combined with a hydraulic chuck and linear guideways, to achieve high-speed, high-precision cutting. The slant bed structure facilitates chip removal and saves space. This machine tool is suitable for machining complex precision parts (such as shafts and discs) and is widely used in the automotive, aerospace, and other fields. It can achieve automated and efficient production through multi-station turrets and CNC systems. The energy-saving slant bed CNC machine tool chip removal device is a highly efficient and energy-saving chip removal system achieved through optimized drive structure and adaptive control technology. Its core design includes a slant-laid conveyor mechanism (such as a chain conveyor or screw conveyor), an energy-saving drive device (such as a time-sharing load motor), and an intelligent adjustment module that automatically adjusts the conveying speed according to the amount of chips generated, avoiding energy waste. This device improves chip removal efficiency through tilting angles and integrates chip and cutting fluid separation functions, reducing manual intervention and mitigating the impact of thermal deformation on machining accuracy. Compared to traditional devices, its energy-saving features are reflected in its intermittent operation mode that only drives the necessary load, and the low maintenance costs resulting from its simplified mechanical structure. For example, prior art publication number CN114406791B discloses an energy-saving slant-type CNC machine tool chip removal device. This device includes a feeding device, a self-adjusting speed transmission device, a feeding device, and an energy-saving drive device. The feeding device includes two supports, each with a hopper. Each hopper has a feeding pipe, and the feeding pipe has an accumulation-type feeding mechanism. In this invention, the drive motor can simultaneously drive both the feeding device and the feeding device, and only one device works at a time, i.e., it only bears the workload of one device. Therefore, it is very energy-efficient and can automatically adjust the chip removal efficiency according to the rate of chip generation, thereby avoiding energy waste caused by exceeding the efficiency limit. The problem with existing technology is that the chip removal device needs to run continuously during chip removal to ensure that the chips do not block the chip removal channel. However, the continuous operation of the chip removal device is not conducive to energy conservation and emission reduction. Furthermore, it cannot handle long metal wires, which significantly increases the risk of blockage in the chip removal channel. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] This invention provides an energy-saving slant-type CNC machine tool chip removal device and method, which can solve the problem of easy clogging in the prior art. The specific solution is as follows: An energy-saving inclined CNC machine tool chip removal device includes an inclined surface inside the machine tool, a chip removal cavity below the inclined surface, the top of the chip removal cavity for collecting chips sliding down from the inclined surface, the bottom of the chip removal cavity penetrating the bottom of the machine tool to achieve the purpose of chip removal, a switch plate is provided on the top of the chip removal cavity, the two ends of the switch plate are hinged to the inner wall of the chip removal cavity, and one end of the switch plate is also connected to a motor, which controls the opening and closing state of the switch plate. The chip removal chamber includes a processing section, inside which guide rollers and guide plates are installed. Guide grooves are provided on the guide plates, and the guide rollers rotate under the drive of the drive source. The processing section is also equipped with a disturbance rod and an inclined guide bar fixed at one end. The disturbance rod is hinged to the inner wall of the processing section by a torsion spring, and the guide bar and the guide groove form a comb-like staggered distribution. The guide bar is also equipped with a cutting rod and a blade connected to its outer wall. The cutting rod rotates under the drive of the drive source. The falling debris is guided by the guide plate and falls onto the inclined guide strip, where it is then cut by the blade. The above solution adopts a structural design of inclined plane and adjustable switch plate. It achieves efficient chip removal by controlling the chip sliding path. The inclined plane guides the chips to automatically gather. With the opening and closing control of the rotatable switch plate, it can not only temporarily store chips during processing, but also form a continuous feeding channel during the chip removal stage, which significantly improves chip removal efficiency. The baffle and arc transition design effectively prevents chips from scattering and keeps the inside of the machine tool clean.

[0005] Preferably, one end of the guide roller is differentially driven with the switch plate through a first gear and a second gear, and the second gear has more teeth than the first gear.

[0006] Preferably, one end of the cutting rod is differentially driven with the first gear through the third gear and the fourth gear, and the number of teeth of the third gear is less than that of the fourth gear.

[0007] Preferably, the ratio of the number of teeth of the first gear to the number of teeth of the second gear is 1:4.

[0008] Preferably, the ratio of the number of teeth of the third gear to the number of teeth of the fourth gear is 1 to 3.

[0009] Preferably, a chip collection box is provided at the bottom of the chip discharge chamber, and a socket is provided below the chip collection box, with the chip collection box slidably installed in the socket.

[0010] Preferably, the chip removal chamber is divided into a feeding chamber, a processing section, an arc section and an inclined section from top to bottom. A receiving groove is also provided on the inner wall of the feeding chamber. The receiving groove is used to accommodate the switch plate in the vertical position.

[0011] Preferably, the two ends of the disturbance rod are fixedly connected to hinged posts, and the inner wall of the processing section is connected to two hinged sleeves. The two hinged sleeves are respectively set at both ends of the disturbance rod. The hinged posts are hinged to the inner wall of the hinged sleeves through torsion springs. The torsion springs allow the hinged posts and the disturbance rod to obtain torsional force. At least one end of the blade is connected to a protrusion. When the cutting rod rotates to a certain angle, the protrusion abuts against the guide bar, causing the guide bar to rotate to one side. When the protrusion separates from the guide bar, it rotates to the other side through the restoring action of the torsion spring, causing the guide bar and the disturbance rod to vibrate. The above solution achieves automatic guiding function through the linkage structure of guide roller and disturbance rod and gear transmission. The cooperation of guide plate and guide bar forms dynamic chip removal channel. The vibration generated by the elastic reset characteristic of disturbance rod can automatically clear stuck chips. This mechanical linkage structure does not require an additional power source and ensures smooth chip removal.

[0012] Preferably, the guide bar has a clearance groove, and the end of the guide bar contacts the inner wall of the guide groove. The blade has a dense serrated cutting edge, and the position and number of several blades correspond to the guide bar. The blades extend into the clearance groove on the guide bar. The above solution, by setting up blades and transmitting the blades through multi-stage gear speed change, can efficiently handle tangled metal wires. The blade assembly and guide strip form a cross-cutting mesh, and the avoidance groove design enables continuous shearing operations, effectively decomposing long filamentous chips. The protrusion structure can enhance the cutting impact force and prevent metal wire from getting stuck, significantly reducing the risk of metal wire entanglement and improving the reliability of the chip removal system.

[0013] On the other hand, the present invention provides an energy-saving chip removal method for a slant CNC machine tool, comprising the following steps: S1. Collect the falling chips by setting a switch plate at the top of the chip discharge chamber below the inclined surface inside the machine tool, and control the opening and closing state of the motor-driven switch plate. S2. The debris falls along the guide plate in the processing section, and the guide rollers and guide grooves guide the direction of the debris movement. S3. The debris is dispersed and guided by the comb-tooth staggered cross structure formed by the inclined guide strip at the end of the disturbance rod and the guide groove. S4. Drive the cutting rod to move the blade to cut and crush the metal chips that have passed through the guide bar; S5. Finally, the processed debris is discharged from the machine tool through the bottom of the chip discharge chamber.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. This invention adopts a structural design of inclined surface and adjustable switch plate. It achieves efficient chip removal by controlling the chip sliding path. The inclined surface guides the chips to automatically gather. With the opening and closing control of the rotatable switch plate, it can not only temporarily store chips during processing, but also form a continuous feeding channel during the chip removal stage, which significantly improves chip removal efficiency. The baffle and arc transition design effectively prevents chips from scattering and keeps the inside of the machine tool clean.

[0015] 2. This invention achieves automatic guiding function through the linkage structure of guide roller and disturbance rod and gear transmission. The cooperation of guide plate and guide bar forms a dynamic chip removal channel. The vibration generated by the elastic reset characteristic of disturbance rod can automatically clear stuck chips. This mechanical linkage structure does not require an additional power source and ensures smooth chip removal.

[0016] 3. This invention, by setting blades and transmitting the blades through multi-stage gear speed change, can efficiently handle tangled metal wires. The blade assembly and guide strip form a cross-cutting mesh, and the avoidance groove design enables continuous shearing operations, effectively decomposing long filamentous chips. The protrusion structure can enhance the cutting impact force and prevent metal wire jamming, significantly reducing the risk of metal wire entanglement and improving the reliability of the chip removal system.

[0017] 4. This invention designs the chip removal chamber with an on / off switch plate to prevent parts from falling into the chip removal chamber during processing. Only after processing is completed and the parts are removed can the switch plate be opened to collect and process the metal chips. The advantage of this is that the collected metal wires are more easily cut into several small segments by the blade, while the scattered metal wires are more likely to detach from the blade and fall directly into the arc segment. Furthermore, the on / off switch plate allows for centralized processing at the end of the processing stage, eliminating the need for the chip removal device to run continuously, thus achieving energy saving.

[0021] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0022] Example 1: As Figure 1 , Figure 2As shown, this embodiment provides an energy-saving inclined CNC machine tool chip removal device, including a chip removal chamber 8, which is located at the bottom of the machine tool 1. The machine tool 1 has a gripper 2 and a tool holder 6 inside, and an inclined surface 7 inside. The inclined surface 7 is used to allow machining chips to slide down to the top of the chip removal chamber 8, thereby achieving the purpose of chip removal. Compared with a flat machining area, the chip removal efficiency is higher. The front of the machine tool 1 is provided with a movable door 3 and a control panel 5. The bottom of the chip removal chamber 8 is provided with a chip collection box 4, and a socket 4a is provided below the chip collection box 4. The socket 4a is used to allow the chip collection box 4 to be stably installed at the bottom of the machine tool 1, thereby effectively collecting the metal chips falling from the chip removal chamber 8.

[0023] like Figure 3 As shown, the chip collection box 4 is located at the lowest point of the inclined plane 7 to effectively collect falling chips. A switch plate 9 is provided at the upper end of the chip collection box 4. One end of the switch plate 9 is hinged to the two inner walls of the chip discharge chamber 8. When the switch plate 9 is in a horizontal state, it can block the top entrance of the chip discharge chamber 8, so that metal chips can fall on the top of the switch plate 9 and will not fall into the chip discharge chamber 8. When the switch plate 9 is in an inclined or vertical state, the top of the chip discharge chamber 8 can form an opening, so that metal chips can fall into the chip discharge chamber 8.

[0024] like Figure 4 As shown, the chip removal chamber 8 is divided into a feeding chamber 8a, a processing section 8b, an arc-shaped section 8c, and an inclined section 8d from top to bottom. A receiving groove 8e is also provided on the inner wall of the feeding chamber 8a. The function of the receiving groove 8e is that when the switch plate 9 is in a vertical state, the switch plate 9 is just contained in the receiving groove 8e. In order to prevent metal chips from falling from the front end of the switch plate 9 into the gap between the machine tool 1 and the movable door 3 when the switch plate 9 is in a horizontal state, a baffle 10 is connected to the end of the switch plate 9 near the movable door 3. The baffle 10 and the switch plate 9 can be perpendicular to each other. In order to avoid creating a dead corner for hygiene, the angle between the baffle 10 and the switch plate 9 is provided with an arc transition.

[0025] like Figure 5As shown, both ends of the switch plate 9 are rotatably connected to the machine tool 1. A motor 11 is also provided at one end of the switch plate 9. The output end of the motor 11 is fixed to one end of the switch plate 9, thereby driving the switch plate 9 to rotate and allowing the switch plate 9 to adjust its tilt angle, thus causing the metal chips to fall selectively. A guide roller 12 is provided inside the processing section 8b. The guide roller 12 has several guide plates 12a. Both ends of the guide roller 12 are rotatably connected to the two inner walls of the processing section 8b. A first gear 13 is connected to the end of the guide roller 12 near the motor 11. The output end of the motor 11 is connected to a second gear 14, which meshes with the first gear 13. The number of teeth of the first gear 13 is less than the number of teeth of the second gear 14. In this embodiment, the ratio of the number of teeth of the first gear 13 to the number of teeth of the second gear 14 is 1:4 (the larger the multiple of the number of teeth of the second gear 14 to the number of teeth of the first gear 13, the better). With the above scheme, when the second gear 14 rotates a quarter turn, the first gear 13 can rotate at least one full turn. The end of the guide plate 12a on the guide roller 12 can contact the inner wall of the processing section 8b.

[0026] like Figure 6 , Figure 7 As shown, a disturbance rod 15 is also provided inside the processing section 8b. The two ends of the disturbance rod 15 are fixedly connected to hinged posts 16. The inner wall of the processing section 8b is connected to two hinged sleeves 18. The two hinged sleeves 18 are respectively located at the two ends of the disturbance rod 15. The hinged posts 16 are hinged to the inner wall of the hinged sleeves 18 through torsion springs 17. As shown in the figure, the torsion springs 17 allow the hinged posts 16 and the disturbance rod 15 to obtain a torsional force that always rotates in the counterclockwise direction.

[0027] like Figure 5 , Figure 8 As shown, the disturbance rod 15 is connected to a number of guide bars 19 at one end near the guide roller 12. A number of guide grooves 12b are provided on the guide plate 12a. The position and number of guide grooves 12b correspond to the position and number of guide bars 19. The guide bars 19 have an inclined angle to the upper right. A clearance groove 20 is provided on the guide bars 19. The end of the guide bar 19 contacts the inner wall of the guide groove 12b.

[0028] In the above scheme, the motor 11 drives the switch plate 9 to rotate, thereby switching the switch plate 9 between open and closed states. This allows metal scraps to remain on the switch plate 9 or fall into the feeding chamber 8a. At the same time, the motor 11 can also drive the guide roller 12 and the guide plate 12a to move counterclockwise through the meshing of the second gear 14 and the first gear 13. Figure 3 , Figure 4 or Figure 6(Direction), when the metal scrap falls into the feeding chamber 8a, it is driven by the guide plate 12a to move with the space between two adjacent guide plates 12a, and finally the metal scrap is guided to the arc section 8c, thereby completing the guidance of the metal scrap and preventing the metal scrap from accumulating in the feeding chamber 8a or the processing section 8b (since the metal needs to be cooled by coolant during processing, the metal scrap is prone to blockage during the scrap discharge process). Furthermore, when a long metal wire appears, due to the cross-guiding effect of the guide groove 12b and the guide bar 19, the horizontal metal wire will be blocked along the tilt angle of the guide bar 19, and the vertical metal wire will also be scraped off at the end of the guide bar 19 and stay on the guide bar 19, which is convenient for subsequent processing.

[0029] like Figure 9 , Figure 10 , Figure 11 As shown, a cutting rod 21 is also provided between the guide roller 12 and the disturbance rod 15. Several blades 22 are fixedly connected to the cutting rod 21. The blades 22 have dense serrated cutting edges. The position and number of the blades 22 correspond to the guide bar 19. The blades 22 extend into the clearance groove 20 on the guide bar 19. A third gear 23 is connected to one end of the cutting rod 21 near the first gear 13. A fourth gear 24 is fixedly connected to one end of the first gear 13. The fourth gear 24 meshes with the third gear 23. The number of teeth of the third gear 23 is less than the number of teeth of the fourth gear 24. In this embodiment, the ratio of the number of teeth of the third gear 23 to the fourth gear 24 is one to three. Therefore, when the first gear 13 and the fourth gear 24 rotate one revolution, the third gear 23 can rotate three revolutions, thereby cutting the metal wire on the guide bar 19 and dividing the long metal wire into several segments, thereby reducing the risk of blockage.

[0030] like Figure 12 As shown, at least one end of the blade 22 is connected to a protrusion 25. When the cutting rod 21 rotates to a certain angle, the protrusion 25 can abut against the guide bar 19. After the protrusion 25 abuts against the guide bar 19, the guide bar 19 can rotate clockwise by a certain angle. After the protrusion 25 separates from the guide bar 19, it is reset by the restoring action of the torsion spring 17 and rotates counterclockwise. This process is repeated. When the protrusion 25 abuts against the guide bar 19 repeatedly, the guide bar 19 and the disturbance rod 15 can vibrate, shaking off the stuck metal wire.

[0031] In the above scheme, through the meshing of the third gear 23 and the fourth gear 24, and with the fourth gear 24 fixed to the first gear 13 at one end of the guide roller 12, the cutting rod 21 can rotate synchronously with the guide roller 12. Under the deceleration effect of the first gear 13, the second gear 14, the third gear 23 and the fourth gear 24, the blade 22 can rotate multiple times when the guide roller 12 rotates once. Therefore, it can effectively cut long metal wires, thereby reducing the risk of long metal wires clogging the chip removal channel.

[0032] Example 2: This example differs from Example 1 in that it provides an energy-saving chip removal method for a slant CNC machine tool, comprising the following steps: S1, Debris Temporary Storage Stage: Metal chips generated during processing slide naturally down the inclined surface 7 inside the machine tool 1 to the top of the chip discharge chamber 8 under the action of gravity. At this time, the motor 11 drives the switch plate 9 to rotate to a horizontal state. The switch plate 9 completely seals the entrance of the chip discharge chamber 8, forming a temporary chip storage platform. The baffle 10 is vertically connected to the switch plate 9 and, with the help of the arc transition structure, effectively prevents chips from overflowing from the gap between the machine tool 1 and the movable door 3, ensuring the sealing of the chip storage area during processing. After the flying chips generated during tool processing hit the surface of the switch plate 9 or the movable door 3, they are bounced back to the center area of ​​the chip storage platform by the vertical obstruction of the baffle 10 or the movable door 3.

[0033] S2, Stage of graded chip removal: After processing is completed, the control panel 5 issues a chip removal command, and the motor 11 drives the switch plate 9 to rotate counterclockwise to an inclined state (approximately 45°-90°). At this time, the inlet of the chip removal chamber 8 is opened. When the switch plate 9 rotates to a vertical state, its end is embedded in the receiving groove 8e to ensure maximum opening. The chips slide along the inclined surface of the switch plate 9 into the feeding chamber 8a. At the junction of the feeding chamber 8a and the processing section 8b, the guide roller 12 begins to rotate counterclockwise (driven by the second gear 14 → first gear 13, with a gear ratio of 1:4, achieving a 4-fold speed increase). The guide plates 12a form a "spiral propulsion" effect in a circumferential distribution, continuously pushing the chips into the processing section 8b. S3, Dynamic Processing Stage: The disturbance rod 15 in the processing section 8b is connected to the torsion spring 17 via the hinged column 16. Under normal conditions, it is pressed tightly against the inner wall of the cavity by the counterclockwise torsional force of the torsion spring 17. When debris passes through, the guide bar 19 and the guide groove 12b form an interlaced comb structure, and process the following types of debris: Lateral debris: Guided by the upper right tilt angle of guide bar 19, it moves towards the lower part of guide bar 19; Vertical debris: After being scraped by the end of guide bar 19, its direction is changed to avoid vertical accumulation; S4, Cutting and Anti-Entanglement Stage: When the guide roller 12 rotates, the cutting rod 21 is driven to rotate at high speed (three times the speed of the guide roller) through the fourth gear 24 fixed at one end. The serrated blade of the blade 22 extends into the clearance groove 20 of the guide bar 19 to form a cross cutting trajectory. The longer metal wire is intercepted by the guide bar 19 and then cut multiple times by the blade 22 as the cutting rod 21 rotates at three times the speed. The cut debris is then placed into the inclined section 8d. The clearance fit between the blade 22 and the guide bar 19 ensures that no metal debris remains. S5. Centralized Collection Phase: The processed debris slides into the chip collection box 4 via the inclined section 8d. The chip collection box is locked to the bottom of the machine tool 1 via the socket 4a to ensure no leakage during transportation.

[0034] In summary, this invention employs a structural design of inclined plane 7 and adjustable switch plate 9. By controlling the chip sliding path, it achieves efficient chip removal. Inclined plane 7 guides the automatic aggregation of chips, and the opening and closing control of the rotatable switch plate 9 allows for temporary storage of chips during processing and the formation of a continuous feeding channel during the chip removal stage, significantly improving chip removal efficiency. The baffle 10 and its arc transition design effectively prevent chip scattering, keeping the machine tool 1 clean. Through the linkage structure of guide roller 12 and disturbance rod 15, automatic guiding is achieved via gear transmission. The cooperation of guide plate 12a and guide bar 19 forms a dynamic chip removal channel. The vibration generated by the elastic reset characteristic of disturbance rod 15 automatically clears stuck chips. This mechanical linkage... The moving structure requires no additional power source, ensuring smooth chip removal. By incorporating blades 22, which are driven by multi-stage gears, it efficiently handles tangled metal wires. The blades 22 and guide bars 19 form a cross-cutting mesh, and the avoidance groove 20 design enables continuous shearing operations, effectively breaking down long, fibrous chips. The protrusion 25 structure enhances cutting impact and prevents wire jamming, significantly reducing the risk of wire entanglement and improving the reliability of the chip removal system. The chip removal chamber 8 is designed as an openable structure using a switch plate 9, preventing parts from falling into it during processing. Only after processing is complete and the parts are removed can the switch plate 9 be opened for centralized processing of metal chips. This design makes it easier for the centralized metal wires to be cut into smaller segments by the blades 22, while loose metal wires fall directly into the curved section 8c.
