Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts processing, and specifically relates to a cooling, cutting and chip collecting device for lightweight materials of new energy vehicles. Background Art

[0002] Cast iron has excellent wear resistance, vibration absorption, excellent casting properties, and low cost, making it widely used in automotive parts such as engine blocks, cylinder heads, transmission housings, flywheels, and crankshafts. During the manufacturing process, these parts often require cutting to obtain the required working surface, of which turning is a key processing method.

[0003] However, cast iron is inherently strong and brittle, making cutting it prone to high cutting temperatures and the generation of large quantities of chips. These chips tend to rebound, causing secondary cutting or extrusion, which not only affects the quality of the machined surface but also shortens the tool life. Furthermore, the flying, hot chips can adversely affect the performance and life of the machine tool. Therefore, chip removal is essential during the machining process.

[0004] To improve machining efficiency, when using large cutting volumes, pouring large amounts of coolant can reduce cutting temperatures, improve machining quality, and increase tool life to a certain extent. However, this method has significant drawbacks, such as environmental pollution and increased costs for part cleaning and chip disposal. Therefore, choosing the right green cooling method is particularly important.

[0005] In summary, in order to eliminate the environmental pollution problems caused by traditional pouring cooling and the various adverse effects caused by chip splashing, and to create a safe and clean processing environment for operators, it is necessary to adopt effective green cooling lubrication and real-time chip removal methods during the cast iron cutting process.

[0058] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0059] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0060] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0062] This application is primarily used in the machining of crankshafts in automotive engine systems. Crankshafts are typically made of ductile iron (e.g., QT800-2). Their structure, consisting of the main journal (main support journal), connecting rod journal (crankpin), balancing weights, flanges, oil holes, and other components, creates a complex overall construction and imposes extremely stringent requirements for dynamic balancing and dimensional accuracy. During the turning process, the outer diameter and end faces of the main journal and connecting rod journal are primarily subjected to fine machining. However, traditional crankshaft turning methods have long been plagued by technical challenges such as severe tool thermal damage and chaotic chip flying. During actual machining, cutting tools are susceptible to thermal damage and failure due to prolonged exposure to high thermal loads. Furthermore, the chaotic flying of metal chips not only reduces the cleanliness of the machining environment but can also pose safety risks. To address these long-standing technical bottlenecks, this technical solution innovatively proposes a dual-channel coordinated cooling and chip removal system. Specifically, first, a cooling nozzle is fixed above the rake face of the turning tool by threaded fastening, and the angle is adjusted to ensure that the cooling spray can accurately cover the cutting area of the tool tip; secondly, an auxiliary nozzle is placed below the flank of the turning tool. This nozzle adopts a dual-function design. On the one hand, it can effectively cool the tool, and on the other hand, it uses the principles of fluid mechanics to guide the chips along a preset trajectory. On this basis, combined with a negative pressure chip collection system, the generated chips can be transported to a closed chip collection device in an orderly and efficient manner. This innovative design successfully solves the prominent problems of tool overheating and chip collection difficulties in traditional machining processes. It not only significantly improves the service life of the tool when machining the crankshaft, but also meets the clean production standards of the workshop's 6S management requirements, bringing a more efficient, safe and environmentally friendly solution to the field of automotive engine crankshaft machining.

[0063] See also Figure 1 As shown, the cooling, cutting and chip collecting device of the lightweight material of the new energy vehicle of the present invention comprises:

[0064] The tool holder 2 is used to support the main structure of the device;

[0065] A cooling turning tool 1 is mounted on the turning tool holder 2. The cooling turning tool 1 includes a tool bar 17, a blade 12 fixed to the tool bar 17, and a plurality of nozzles connected to both sides of the tool bar 17. The nozzles on both sides of the tool bar 17 are respectively directed towards the rake face and the flank face of the blade 12 for spraying a cooling medium onto the cutting area.

[0066] A negative pressure assembly 4 is provided on the tool holder 2. The negative pressure assembly 4 includes a negative pressure pipe 42. The negative pressure port of the negative pressure pipe 42 is aligned with the working end of the blade 12 and is used to absorb chips generated by cutting.

[0067] An adjustment assembly, used to install the negative pressure assembly 4 on the tool holder 2, the adjustment assembly comprising a displacement adjustment platform 7, an angle adjustment platform 6 and a pipeline mounting member connected to the tool holder 2;

[0068] Among them, the displacement adjustment platform 7 is used to drive the pipeline mounting part to perform displacement adjustment relative to the negative pressure tube 42 in the horizontal direction, the angle adjustment platform 6 is used to drive the pipeline mounting part to perform rotation angle adjustment around the axis of the negative pressure tube 42, and the pipeline mounting part is used to fix the connection between the negative pressure tube 42 and the tool holder 2.

[0069] In this embodiment, the nozzle on one side of the knife rod 17 is the first nozzle 14 , and the nozzle on the other side of the knife rod 17 is the second nozzle 172 .

[0070] It's worth noting that the user can adjust the displacement adjustment platform 7 to drive it forward and backward, thereby adjusting the pipe mounting assembly's horizontal displacement relative to the negative pressure tube 42. Subsequently, by adjusting the angle adjustment platform 6, the pipe mounting assembly rotates about the axis of the negative pressure tube 42, completing the angle adjustment and precisely aligning the negative pressure tube 42 with the air pipe 43 of the negative pressure assembly 4. Once connected, align the negative pressure port of the negative pressure tube 42 with the working end (cutting area) of the blade 12.

[0071] As blade 12 cuts along the workpiece 3's machining plane, vacuum blower 9 and two nozzles of vacuum assembly 4 are simultaneously activated. Vacuum blower 9 draws in chips through negative pressure, while an external spray cooling system directs a cooling medium through two nozzles into the cutting zone. This spray cools the cutting zone, preventing tool overheating, while also forcing the chips toward the negative pressure port of vacuum pipe 42 through the airflow, facilitating efficient chip collection by the vacuum chip collection system.

[0072] The collaborative design of dual-side nozzle cooling and negative pressure chip collection achieves integrated cooling and chip removal. The directional spray not only reduces the temperature in the cutting zone but also guides the chip's path, while negative pressure suction directly removes scattered debris, avoiding the inefficiencies associated with the separation of cooling and chip removal in traditional machining. This synergistic mechanism significantly improves surface quality, tool life, and environmental friendliness, while providing a cleaner and safer working environment for operators.

[0073] See also Figures 2 to 6 As shown, specifically, the displacement adjustment platform 7 includes a displacement base 73, a displacement workbench 71 disposed on the displacement base 73 via a slider guide structure 712, a rotary differential head 75 disposed on one side of the displacement base 73, and a rotary stop screw 72 disposed on one side of the displacement workbench 71;

[0074] A mounting plate extends from one side of the displacement base 73, and a drive plate extends from one side of the displacement workbench 71. The rotary differential head 75 is mounted on the mounting plate, and the working end of the rotary differential head 75 is connected to the drive plate. The rotary differential head 75 drives the drive plate to move relative to the mounting plate, thereby driving the displacement workbench 71 to move.

[0075] The rotating set screw 72 is used to lock the position of the displacement table 71 relative to the displacement base 73. When the displacement table 71 is moved to a certain position, the rotation of the differential head 75 drives the displacement table 71 to precisely adjust its horizontal displacement by ±3 mm, ensuring accurate alignment between the vacuum tube 42 and the working end of the blade 12 and preventing chip residue. After the displacement adjustment is completed, the position of the displacement table 71 is locked by rotating the set screw 72 to prevent it from shifting during processing.

[0076] More specifically, a first groove is formed on a side of the displacement workbench 71 close to the displacement base 73 , and a second groove is formed on a side of the displacement base 73 close to the displacement workbench 71 , wherein the second groove and the first groove form a receiving groove;

[0077] An elastic resistance structure is provided between the displacement base 73 and the displacement workbench 71. A first groove is provided on the side of the displacement base 73 near the displacement workbench 71, and a second groove is provided on the corresponding position of the displacement workbench 71. The two grooves are joined to form a receiving slot. A first fixing pier 711 is provided on the inner wall of the first groove, and a second fixing pier 731 is provided on the inner wall of the second groove. A spring is installed between the two fixing piers as an elastic member 74, with both ends of the spring hooked onto the fixing piers. This elastic structure increases the motion resistance between the displacement base 73 and the displacement workbench 71, improving the stability and operational feel of the adjustment process and preventing position deviation caused by external force disturbances.

[0078] Specifically, the angle adjustment platform 6 includes an angle base 63, an angle workbench 61 provided on the angle base 63, and a driving structure and a locking screw 62 provided between the angle base 63 and the angle workbench 61;

[0079] The driving structure includes a worm 641 disposed inside the angle base 63, a feed knob 64 connected to one end of the worm 641 and extending to the outside of the angle base 63, and a worm wheel 611 disposed inside the angle workbench 61;

[0080] The worm 641 is engaged with the lowest point of the worm wheel 611. By rotating the feed knob 64, the worm 641 drives the worm wheel 611 to rotate the angle table 61 relative to the angle base table 63. The locking screw 62 is used to lock the position of the angle table 61 relative to the angle base table 63. When the feed knob 64 is rotated, the worm 641 drives the worm wheel 611 to rotate, causing the angle table 61 to rotate relative to the base table to achieve an angle adjustment of ±10°. After the adjustment is completed, the position of the angle table 61 is fixed by the locking screw 62 to prevent the machining vibration from causing deviation and ensure the stability of the system. The angle adjustment platform 6 and the displacement adjustment platform 7 work together to fine-tune the rotation and displacement of the position of the negative pressure tube 42. Through the precise transmission of the worm wheel 611 and the worm 641, combined with the rigid fixation of the locking screw 62, the position deviation of the negative pressure tube 42 during the connection process can be corrected in time to ensure that it is always aligned with the working end of the blade 12, thereby maintaining chip removal efficiency and machining accuracy.

[0081] See also Figures 7 and 8 As shown, further, the pipeline mounting member includes an upper portion 51 of the air pipe clamp and a lower portion 52 of the air pipe clamp;

[0082] The air clamp lower portion 52 includes a connecting block 522, a pad 521 mounted on the connecting block 522, and a first screw 523 provided on the connecting block 522. The air clamp lower portion 52 is fixed to the tool holder 2 via the first screw 523.

[0083] The upper portion 51 of the air-clamping tube includes a lower connecting frame 513 and an upper connecting frame 512 connected to the lower connecting frame 513 via a second screw 511. The lower connecting frame 513 and the upper connecting frame 512 are each provided with an arcuate groove on adjacent sides. The two arcuate grooves cooperate to form a clamping groove for clamping the interface of the negative pressure tube 42. During ventilation, if the negative pressure tube 42 becomes slightly loose, the second screw 511 needs to be adjusted promptly to tighten the connection between the upper connecting frame 512 and the negative pressure tube 42 to prevent air leakage during ventilation.

[0084] See also Figures 9 to 13 As shown, specifically, the cooling turning tool 1 further includes a tool pad 11 mounted on the tool rod 17, and a pressure plate 16 mounted on the tool rod 17 through a pressure plate bolt 15;

[0085] The working end of the pressing plate 16 is pressed on the blade 12 , and the knife pad 11 and the blade 12 are fixed to the knife rod 17 via a tool screw 13 .

[0086] Furthermore, the cooling turning tool 1 further includes a chip guard assembly 18, and the chip guard assembly 18 includes a chip guard straight plate 181 and a chip guard elbow 182 connected to the chip guard straight plate 181;

[0087] The chip blocking curved pipe 182 is arranged directly above the blade 12, and the chip blocking straight plate 181 is arranged on the side of the blade 12 to block the chips flying during the cutting process.

[0088] In this embodiment, the blade 12 is fixed in the blade 12 mounting groove of the tool rod 17 together with the tool screw 13 and the tool pad 11, and is pressed by the pressure plate 16 through the pressure plate bolt 15 on the top to ensure that the blade 12 is firm and stable during the cutting process. The end of the tool rod 17 is a cutter head, which is integrally embedded in the internal structure of the turning tool holder 2 to form a rigid support structure. The chip guard assembly 18 is mounted on the tool rod 17 by bolts and includes a chip guard straight plate 181 and a chip guard curved pipe 182. The chip guard straight plate 181 is located on the side of the blade 12 and is mainly used to block the chips flying directly in front of the workpiece 3; the chip guard curved pipe 182 is arranged directly above the blade 12 to block the debris from above the workpiece 3, and the chip diffusion is reduced in both directions. The cooling system is integrated into the tool rod 17, and the external spray cooling medium is input through the pipe interface 171 at the bottom of the tool rod 17 and transported to the two nozzles through the internal cooling channel. The first nozzle 14 is located above the tool bar 17 and secured by a threaded connection. The nozzle outlet is precisely aligned with the tool tip, directly cooling the cutting area. The second nozzle 172 is located below the tool flank, with the nozzle outlet facing upward toward the chip generation area. This not only cools the blade 12 but also guides the chips toward the negative pressure suction nozzle 41 through the spray airflow. The coordinated design of these two nozzles and the negative pressure suction nozzle 41 allows the chips to be efficiently sucked and collected by the negative pressure system under the influence of the cooling airflow, achieving integrated cooling, lubrication, and chip removal functions.

[0089] Specifically, the negative pressure assembly 4 includes a suction nozzle 41 connected to one end of the negative pressure pipe 42, and a negative pressure fan 9 connected to the other end of the negative pressure pipe 42;

[0090] The nozzle 41 includes a nozzle outer ring 411 , a nozzle opening 412 disposed on the nozzle outer ring 411 , and an outer ring notch 4111 opened on one side of the nozzle outer ring 411 ;

[0091] In this embodiment, a suction nozzle 41 is located at one end of a negative pressure tube 42. Its outer ring has an arc-shaped cross-section, which can wrap around the surface of the workpiece 3 to be cut. A notch is provided on one side of the outer ring to prevent the blade 12 from entering the cutting area. A suction nozzle opening 412 is provided on the outer ring and works in conjunction with the negative pressure blower 9 to collect chips through the negative pressure airflow, reducing splashing and secondary contamination, and significantly improving collection efficiency.

[0092] The curved outer ring of the suction nozzle 41 preferably wraps around the workpiece 3 while providing space for the tool to operate. This ensures both flexible cutting contact and airtight chip absorption. The first and second nozzles 14, 172 can be cylindrical, flat, or pointed, depending on the application. Flexible placement options are available—they can be installed individually on the top or bottom of the tool head, or multiple nozzles can be deployed simultaneously to accommodate different processing scenarios.

[0093] The core functions of the suction nozzle 41 include directing and focusing airflow, suppressing chip scattering, and providing a secure connection to the air pipe 43. Its structural design significantly improves chip collection efficiency by optimizing the airflow path and providing space for tool clearance. Furthermore, the outer ring notch 4111 ensures unobstructed contact between the cooling turning tool 1 and the workpiece 3, balancing machining accuracy and chip recovery requirements.

[0094] See also Figure 14 As shown, more specifically, the negative pressure assembly 4 further includes a chip box 8 and an air pipe 43 connected to the chip box 8 , and the air pipe 43 is communicated with the negative pressure pipe 42 .

[0095] In this embodiment, the suction nozzle 41 communicates with the air pipe 43 of the chip box 8 via a negative pressure pipe 42. The chip box 8 includes an outer frame 84, within which are located a buffer plate 83 and an inclined platform 82. The buffer plate 83, located near the entrance of the air pipe 43, slows the rate at which chips fall to the bottom of the box. The inclined platform 82 is designed with a thickened bottom structure, which not only enhances the box's pressure-bearing capacity but also further cushions chip accumulation through its inclined surface. A pulley 81 is installed at the bottom of the chip box 8 for easy movement. A slidable plate 85 is installed on one side of the box, which slides downward to open a cleaning port for rapid chip removal.

[0096] A negative pressure blower 9 is mounted on top of the chip box 8. Its internal motor generates suction, creating a negative pressure differential near the suction nozzle 412. Chips flow through the suction nozzle 41 and air pipe 43 into the chip box 8. A filter 10 is positioned between the negative pressure blower 9 and the chip box 8 to intercept metal chips and sediment, preventing impurities from entering the blower and causing wear. During the cutting process, chips are drawn from the surface of the workpiece 3 into the suction nozzle 41, flow through the air pipe 43, and fall into the chip box 8. When a sufficient amount accumulates, they are collected and cleared by a sliding plate 85, forming a continuous cycle.

[0097] The negative pressure pipe 42 is provided with air gaskets 422 at both ends thereof for sealing the airtightness of the connection between the negative pressure pipe 42 and the outside. The negative pressure pipe 42 comprises two connecting pipes 421 connected at right angles.

[0098] In summary, in the cooling, cutting, and chip collection device for lightweight materials used in new energy vehicles in the aforementioned embodiments of the present invention, the user can adjust the displacement adjustment platform 7 to move forward and backward, thereby causing the pipeline mounting member to move forward and backward horizontally relative to the negative pressure tube 42. Subsequently, by adjusting the angle adjustment platform 6, the pipeline mounting member is driven to rotate about the axis of the negative pressure tube 42 to complete the angle adjustment, precisely connecting the negative pressure tube 42 with the air pipe 43 of the negative pressure assembly 4. After the connection is completed, the negative pressure port of the negative pressure tube 42 is aligned with the working end (cutting area) of the blade 12.

[0099] As blade 12 cuts along the workpiece 3's machining plane, vacuum blower 9 and two nozzles of vacuum assembly 4 are simultaneously activated. Vacuum blower 9 draws in chips through negative pressure, while an external spray cooling system directs a cooling medium through two nozzles into the cutting zone. This spray cools the cutting zone, preventing tool overheating, while also forcing the chips toward the negative pressure port of vacuum pipe 42 through the airflow, facilitating efficient chip collection by the vacuum chip collection system.

[0100] The collaborative design of dual-side nozzle cooling and negative pressure chip collection achieves integrated cooling and chip removal. The directional spray not only reduces the temperature in the cutting zone but also guides the chip's path, while negative pressure suction directly removes scattered debris, avoiding the inefficiencies associated with the separation of cooling and chip removal in traditional machining. This synergistic mechanism significantly improves surface quality, tool life, and environmental friendliness, while providing a cleaner and safer working environment for operators.
