Description

Technical Field

[0001] This invention mainly relates to the field of cutting cooling and chip removal, specifically a cutting cooling and chip removal device for a CNC horizontal milling and boring machine and its usage method. Background Technology

[0002] As one of the core equipment in modern manufacturing, CNC horizontal milling and boring machines are widely used for the precision machining of complex parts such as large boxes, shells, and molds, and are indispensable, especially in aerospace, energy equipment, and heavy machinery. Their powerful milling and boring capabilities enable them to perform various processes, including planar, curved, hole, and thread machining. With the expansion of machining materials to include difficult-to-machine materials such as high-strength alloy steel, high-temperature alloys, titanium alloys, and composite materials, and the increasing complexity of part structures (such as multi-cavity, deep holes, thin walls, and irregular shapes), higher demands are placed on the stability, accuracy, and efficiency of the machining process.

[0003] In high-speed, high-efficiency, and heavy-duty cutting, especially when machining difficult-to-machine materials or performing complex operations such as deep hole boring and large-mass milling, a large amount of heat and chips are generated in the cutting zone. Effective cutting cooling and chip removal are crucial for protecting the tool, ensuring accuracy, improving efficiency, enhancing surface quality, and ensuring safety. However, existing cooling and chip removal technologies still have certain limitations.

[0004] Currently, general-purpose overflow cooling systems inject coolant into the cutting area through nozzles, serving both cooling and chip removal purposes. However, coolant utilization is low, energy consumption is high, and the cooling effect is poor for specific machining points or deep cavities, making it difficult to adapt to the varying cooling characteristics required by different machining materials. Standalone high-pressure cooling systems are used for deep hole machining or difficult-to-machine materials, increasing coolant jet velocity and penetration. However, their installation position is fixed or their adjustment range is limited, making it difficult to achieve precise dynamic coolant spraying in the complex and variable machining trajectories of milling and boring machines. Furthermore, high-pressure systems consume a significant amount of energy. Basic chain-plate or spiral chip conveyors are used to collect and transport chips, but these devices are often independent of the cooling system, with limited capacity to handle viscous chips, long, coiled chips, or chips of mixed materials. They are prone to clogging and have difficulty effectively handling chips adhering to the workpiece or fixture. In addition, simple protective and mist-absorbing devices are mainly for safety and environmental protection, offering limited improvement to the core cooling and chip removal efficiency.

[0005] Existing technologies are mostly general-purpose or designed for single machining methods, and have significant shortcomings when addressing specific combined metal machining needs. For example, when machining tasks involve multiple different metal materials or multiple processes closely integrated, general-purpose cooling and chip removal systems struggle to meet differentiated and dynamically changing requirements. Cooling systems, chip removal systems, and protection systems are often designed and operated independently, lacking integrated design, resulting in large space requirements, complex piping, and decentralized control, making it difficult to achieve efficient coordination between cooling and chip removal. Furthermore, under CNC program control, tool paths and machining areas change rapidly, and existing fixed or limitedly adjustable cooling nozzles and chip removal ports cannot accurately follow the tool position in real time or adapt to different process transitions, potentially leading to cooling blind spots or poor chip removal. In terms of intelligence, existing technologies lack intelligent sensing and feedback control capabilities based on machining parameters and real-time operating conditions, making it difficult to automatically optimize coolant supply and chip removal intensity.

[0006] Therefore, the market urgently needs a highly integrated, intelligent, and dynamically configurable cutting cooling and chip removal device specifically designed for CNC horizontal milling and boring machines to solve the above problems and significantly improve machining efficiency, quality, tool life, and equipment reliability under complex and demanding working conditions. Summary of the Invention

[0007] This invention provides a cutting cooling and chip removal device for a CNC horizontal milling and boring machine to address the shortcomings of the prior art mentioned in the background section.

[0008] A cutting cooling and chip removal device for a CNC horizontal milling and boring machine includes a base with two symmetrically distributed supporting longitudinal beams. A crossbeam bracket is vertically installed between the two supporting longitudinal beams. Each supporting longitudinal beam has a fixedly mounted caster at its bottom end and a height-adjustable support at its bottom. Longitudinal sliding devices are fixedly mounted on opposite sides of each supporting longitudinal beam. A fixed bracket is fixedly mounted at the drive end of each longitudinal sliding device. An angle adjustment component is mounted on the bottom surface of the fixed bracket, and a proximity bracket is mounted on the bottom surface of the angle adjustment component. The angle adjustment component can control the rotation of the proximity bracket. A cooling spray component and a chip removal component are mounted on the bottom surface of the proximity bracket.

[0009] Furthermore, the angle adjustment assembly includes two sets of bearing seats, one of which is mounted on the bottom surface of the fixed bracket, and the proximity bracket is hinged between the two sets of bearing seats.

[0010] Furthermore, the angle adjustment component includes a drive motor disposed on the top of the bracket, a drive gear is mounted on the output end of the drive motor, and an arc-shaped rack meshing with the drive gear is disposed on the top surface of the bracket.

[0011] Furthermore, the longitudinal sliding device includes a guide rail, which is vertically arranged on the inner side of the supporting longitudinal beam. The guide rail has bearing seats at both ends, and the bearing seats support a screw shaft. The top of the screw shaft is rotatably connected to a longitudinal motor via a coupling. A connecting slider is provided on the guide rail, and the connecting slider is threadedly connected to the screw shaft; the connecting slider is fixedly connected to the fixed bracket.

[0012] Furthermore, the cooling spray assembly includes a transverse drive screw mechanism disposed near the bottom surface of the support. The transverse drive screw mechanism includes multiple drive sliders. A transverse L-shaped mounting base is fixedly installed at the bottom of the drive slider. A rotating tube is disposed on the horizontal part of the L-shaped mounting base through a bearing. A coolant inlet pipe is clamped and connected to the top of the rotating tube. An atomizing nozzle is connected to the bottom of the rotating tube.

[0013] Furthermore, a bevel gear one is provided on the upper part of the rotating tube, and a bevel gear two is meshed with the bevel gear one. The bevel gear two is mounted on the rotating motor, and the rotating motor is fixedly mounted on the bottom of the L-shaped mounting base.

[0014] Furthermore, the chip removal assembly includes a sliding frame, which is fixedly installed on the bottom surface close to the bracket and disposed on one side of the cooling spray assembly; The sliding frame is equipped with a sliding seat, and a transmission screw is rotatably installed in the sliding frame. The sliding seat is threadedly installed on the lower side of the transmission screw. A nozzle bracket is installed on the bottom surface of the sliding seat, and a high-pressure nozzle is hinged on the nozzle bracket. The high-pressure nozzle can rotate in a vertical plane.

[0015] Furthermore, a protective cover is fixedly installed on the side end of the L-shaped mounting base, and the first gear, the second bevel gear, and the rotating motor are all located in the protective cover.

[0016] A method of using the cutting cooling and chip removal device for a CNC horizontal milling and boring machine as described above includes the following steps: Step 1: Device placement and preliminary adjustment 1.1 Use the moving wheels to push the base to the vicinity of the machining area of ​​the CNC horizontal milling and boring machine to complete the process; 1.2 Adjust the height of the support to raise the bottom of the support beam and remove it from the milling plane. Adjust the base to a horizontal state using a level. 1.3 Start the longitudinal motor of the longitudinal sliding device to drive the screw shaft to rotate, which in turn moves the connecting slider along the guide rail. Adjust the fixed bracket to a suitable height so that the bracket is initially close to the workpiece processing area. Step 2: Precisely adjust the angle and position close to the bracket. 2.1 Start the drive motor of the angle adjustment component, drive the gear and the arc rack to mesh and drive the bracket to rotate around the bearing seat, and adjust the parallelism between its bottom surface and the workpiece processing surface; 2.2 After adjustment, restart the longitudinal sliding device and fine-tune the height of the fixed bracket; Step 3: Deployment and cooling operation of the cooling jet assembly 3.1 Start the transverse drive screw mechanism of the cooling spray assembly, drive the slider to move the L-shaped mounting base laterally, and adjust the atomizing nozzle to be directly above the workpiece cutting area; 3.2 Start the rotating motor, which drives the rotating tube to rotate through bevel gear one and bevel gear two. Adjust the spray angle of the atomizing nozzle to be perpendicular to the cutting edge to ensure that the coolant evenly covers the cutting area. 3.3 Connect the external coolant pump and start the pumping system. The coolant enters the rotating tube through the coolant inlet pipe and is sprayed out by the atomizing nozzle to cool the cutting area. Step 4: Deployment and operation of the chip removal components 4.1 Start the drive screw of the chip removal assembly to drive the sliding seat to move along the sliding frame, and adjust the high-pressure nozzle to be directly above the cutting area; 4.2 Adjust the hinge angle of the high-pressure nozzle so that its spray direction forms an angle of 30°~45° with the workpiece surface; 4.3 Connect an external high-pressure water source or compressed air source, start the pumping system, and the high-pressure medium is sprayed out at high speed through the high-pressure nozzle to flush the chips accumulated in the cutting area to the machine tool chip discharge groove. 4.4 The transmission screw drives the sliding seat to reciprocate along the sliding frame, synchronously adjusting the position of the high-pressure nozzle for multi-angle chip removal; Step 5: Coordinated operation of cooling and chip removal 5.1 Alternating operation of cooling spray assembly and chip removal assembly: During the cutting process, the cooling spray assembly continuously supplies coolant; during the cutting gap, the chip removal assembly starts chip removal. 5.2 For deep cavity machining, the height of the attachment bracket is adjusted by the longitudinal sliding device so that the atomizing nozzle and the high-pressure nozzle are aligned with the cavity to complete cooling and chip removal respectively; 5.3 Monitor the status of the cutting area in real time. If chips accumulate, activate the chip removal component first to clean them up, and then restore cooling.

[0017] The beneficial effects of this invention are as follows: By setting an angle adjustment component, the angle position of the contact bracket can be flexibly adjusted so that the bottom end of the contact bracket contacts the workpiece processing surface. This facilitates the adjustment of the tilting angle of the cooling nozzle, high-pressure spray mechanism, and low-pressure overflow mechanism, which in turn facilitates subsequent cooling and chip removal of the workpiece processing area without disassembling the workpiece, thus improving the cooling and chip removal efficiency of the workpiece processing area.

[0018] By setting up a cooling spray assembly, the workpiece machining area can be cooled and chipped in multiple modes. This facilitates the subsequent use of cooling nozzles to cool the workpiece machining area comprehensively. Since the high-pressure nozzles have already performed preliminary cooling and chip removal on the cutting area, the coolant can cover the workpiece machining area more evenly, improving the cooling quality of the workpiece machining area.

[0019] By setting up a cooling spray assembly, the workpiece processing area can be directly cooled and chip removed, resulting in a smooth workpiece surface without residual chips. This eliminates the need to disassemble the workpiece, further improving the cooling and chip removal efficiency of the workpiece processing area. Attached Figure Description

[0029] This invention provides a cutting cooling and chip removal device for a CNC horizontal milling and boring machine and its usage method. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings. Figure 1 , 2 This is a schematic diagram of the overall structure of the present invention, showing the layout of the base 1, supporting longitudinal beams 101, longitudinal sliding device 2, fixed bracket 3, fitting bracket 5, cooling spray assembly 6, chip removal assembly 7, and control module 8. Two supporting longitudinal beams 101 are fixed to the top of the base 1 by welding or bolting. The two supporting longitudinal beams 101 are connected by a crossbeam bracket 102 to enhance the stability of the overall structure. The bottom of the supporting longitudinal beams 101 is equipped with casters 103 and a height-adjustable support 104. The casters 103 are used for flexible movement of the device, while the height-adjustable support 104 is used to adjust the height of the base 1 and ensure its levelness. The moving wheel 103 is driven and controlled by a moving motor. A longitudinal sliding mechanism 2 is provided on the inner side of the supporting longitudinal beam 101. The driving end of the longitudinal sliding mechanism 2 is connected to the fixed bracket 3. An angle adjustment mechanism 4 is installed on the bottom surface of the fixed bracket 3. The bottom surface of the angle adjustment mechanism 4 is connected to the fitting bracket 5. A cooling spray assembly 6 and a chip removal assembly 7 are provided on the bottom surface of the fitting bracket 5. The control module 8 is installed on the top surface of the fixed bracket 3 and can control the moving motor, as well as the longitudinal motor 204, drive motor 404, rotation motor 607 and micro sliding motor 706 mentioned later in this document.

[0030] The longitudinal sliding mechanism 2 includes a guide rail 201, which is vertically fixed to the inner side of the supporting longitudinal beam 101. Bearing seats 202 are provided at both ends of the guide rail 201, and a screw shaft 203 is installed inside the bearing seats 202. The top of the screw shaft 203 is connected to the longitudinal motor 204 via a coupling. Figure 4 As shown. A connecting slider 205 is provided on the guide rail 201. The connecting slider 205 is threadedly connected to the screw shaft 203, and the outer surface of the connecting slider 205 is fixed to the fixed bracket 3 by bolts. The working principle of the longitudinal sliding mechanism 2 is that the longitudinal motor 204 drives the screw shaft 203 to rotate, causing the connecting slider 205 to move up and down along the guide rail 201, thereby driving the fixed bracket 3 and the angle adjustment mechanism 4 and the fitting bracket 5 connected to it to achieve height adjustment. The angle adjustment mechanism 4 includes two sets of bearing seats 401, which are fixed to the bottom surface of the fixed bracket 3 by bolts. The fitting bracket 5 is installed between the two sets of bearing seats 401 by hinge. The angle adjustment mechanism 4 also includes a drive motor 404. A drive gear 402 is installed at the output end of the drive motor 404. The drive gear 402 meshes with an arc-shaped rack 403, which is fixed to the top surface of the fitting bracket 5 by bolts. Figure 5As shown. The drive motor 404 drives the fitting bracket 5 to rotate around the bearing seat 401 through the meshing transmission of the drive gear 402 and the arc rack 403, thereby realizing the angle adjustment of the fitting bracket 5.

[0031] As shown in the figure (Note: For ease of illustration, the length of the drive screw mechanism 601 is shown in the figure), the cooling spray assembly 6 includes a transverse drive screw mechanism 601. The drive end of the transverse drive screw mechanism 601 is connected to multiple drive sliders 6011. An L-shaped mounting base 602 is fixed to the bottom of each drive slider 6011 by bolts. A rotating tube 603 is mounted on the horizontal part of the L-shaped mounting base 602 via bearings. The top of the rotating tube 603 is connected to a coolant delivery pipe, and an atomizing nozzle 604 is provided at the bottom of the rotating tube 603. Figure 2 As shown. A bevel gear 605 is mounted on the upper part of the rotating tube 603. The bevel gear 605 meshes with a second bevel gear 606, which is driven by a rotating motor 607. The rotating motor 607 is bolted to the bottom of the L-shaped mounting base 602. A protective cover is bolted to the side of the L-shaped mounting base 602. The bevel gears 605, 606, and the rotating motor 607 are all located inside the protective cover, and the outer surface of the protective cover has heat dissipation holes. The cooling spray assembly 6 works by using a transverse drive screw mechanism 601 to drive a slider 6011 to move laterally along the guide rail, thereby adjusting the position of the L-shaped mounting base 602 and the connected rotating tube 603 and atomizing nozzle 604. The rotating motor 607, through the meshing of the bevel gears 605 and 606, drives the rotating tube 603 to rotate, thereby adjusting the spray angle of the atomizing nozzle 604. Coolant enters the coolant delivery pipe from the external coolant pump, is delivered to the atomizing nozzle 604 via the rotating pipe 603, and is finally sprayed out to cover the cutting area.

[0032] The chip removal assembly 7 includes a sliding frame 701, which is bolted to the bottom surface of the fitting bracket 5. A transmission screw 703 is installed inside the sliding frame 701, and a sliding seat 702 is threaded onto the outer surface of the transmission screw 703. Figure 3As shown, a miniature sliding motor 706 connected to a transmission screw 703 is provided at the end of the sliding frame 701. A nozzle bracket 704 is bolted to the bottom of the sliding seat 702, and a high-pressure nozzle 705 is hinged to the nozzle bracket 704. The high-pressure nozzle 705 can be adjusted in angle in the vertical plane. The working principle of the chip removal assembly 7 is that the transmission screw 703 drives the sliding seat 702 to move along the sliding frame 701, thereby driving the nozzle bracket 704 and the high-pressure nozzle 705 connected to it to adjust their positions. The spray direction of the high-pressure nozzle 705 can be adjusted to form an angle of 30° to 45° with the workpiece surface. An elastic buffer pad is provided at the bottom of the nozzle bracket 704 to reduce the vibration of the high-pressure nozzle 705 during operation. The high-pressure medium enters the high-pressure nozzle 705 from an external high-pressure water source or compressed air source, and after being sprayed out at high speed, it washes the chips accumulated in the cutting area to the machine tool chip removal groove.

[0033] The method of using this device is as follows: First, the base 1 is pushed to the vicinity of the machining area of ​​the CNC horizontal milling and boring machine using the moving wheels 103, and the height of the height adjustment support 104 is adjusted to ensure that the bottom end of the supporting longitudinal beam 101 is detached from the machining plane. After calibrating the base 1 to a horizontal state using a level, the longitudinal motor 204 in the longitudinal sliding mechanism 2 is started, driving the screw shaft 203 to rotate, thereby causing the connecting slider 205 to move up and down along the guide rail 201. The fixed bracket 3 is connected to the connecting slider 205, and its height is adjusted accordingly, driving the angle adjustment mechanism 4 and the contact bracket 5 closer to the workpiece machining area. During this process, the longitudinal sliding mechanism 2 achieves precise height control through the threaded engagement between the screw shaft 203 and the connecting slider 205, ensuring that the cooling spray assembly 6 and the chip removal assembly 7 can be initially positioned near the machining area.

[0034] Next, the drive motor 404 in the angle adjustment mechanism 4 is activated, driving the gear 402 to mesh with the arc-shaped rack 403, causing the fitting bracket 5 to rotate around the bearing seat 401 to adjust the parallelism between the bottom surface of the fitting bracket 5 and the workpiece machining surface. Through the meshing design of the drive gear 402 and the arc-shaped rack 403, the angle adjustment mechanism 4 can achieve fine-tuning of the angle of the fitting bracket 5, thereby ensuring that the working surfaces of the cooling spray assembly 6 and the chip removal assembly 7 maintain optimal contact with the workpiece surface. After the angle adjustment is completed, the longitudinal sliding mechanism 2 is activated again to fine-tune the height of the fixed bracket 3, making the position of the fitting bracket 5 more precise.

[0035] Subsequently, the transverse drive screw mechanism 601 in the cooling spray assembly 6 is activated, driving the drive slider 6011 to move laterally along the guide rail, thereby adjusting the position of the L-shaped mounting base 602 and its connected rotating tube 603 and atomizing nozzle 604. The rotating motor 607, through the meshing of bevel gear one 605 and bevel gear two 606, drives the rotating tube 603 to rotate, thus adjusting the spray angle of the atomizing nozzle 604 to be perpendicular to the cutting edge. Coolant enters the coolant delivery pipe from an external coolant pump, is delivered through the rotating tube 603 to the atomizing nozzle 604, and is finally sprayed evenly onto the cutting area. Through the design of the transverse drive screw mechanism 601 and the rotating tube 603, the cooling spray assembly 6 can achieve multi-angle, full-coverage spraying of coolant, effectively reducing cooling blind spots.

[0036] The drive screw 703 in the chip removal assembly 7 is activated, driving the sliding seat 702 to move along the sliding frame 701, thereby adjusting the position of the nozzle support 704 and the high-pressure nozzle 705 connected to it. The hinge angle of the high-pressure nozzle 705 can be adjusted to form an angle of 30° to 45° with the workpiece surface to optimize the spray direction. The high-pressure medium enters the high-pressure nozzle 705 from an external high-pressure water source or compressed air source, and after being sprayed out at high speed, it washes the chips accumulated in the cutting area to the machine tool chip removal groove. The threaded connection design between the drive screw 703 and the sliding seat 702 enables the high-pressure nozzle 705 to achieve multi-angle, reciprocating chip removal operation, significantly improving chip removal efficiency.

[0037] During actual machining, the cooling spray assembly 6 and the chip removal assembly 7 operate alternately. When the tool is cutting, the cooling spray assembly 6 continuously provides coolant to reduce the cutting temperature and extend tool life; when the tool stops cutting, the chip removal assembly 7 is activated to quickly remove chips from the cutting area. For deep cavity machining, the height of the fitting bracket 5 is adjusted by the longitudinal sliding mechanism 2 so that the atomizing nozzle 604 and the high-pressure nozzle 705 are aligned with the cavity to complete the cooling and chip removal tasks respectively. When the cutting area status is monitored in real time, if chip accumulation is detected, the chip removal assembly 7 is activated first to clean it, and then the cooling operation is resumed.

[0038] Through the above steps, this device achieves efficient utilization of coolant and rapid chip removal. The cooling spray assembly 6, through the cooperation of the transverse drive screw mechanism 601 and the rotating tube 603, optimizes the spray angle and coverage of the coolant, reducing the generation of cooling blind spots. The chip removal assembly 7, through the multi-angle adjustment design of the drive screw 703 and the high-pressure nozzle 705, effectively removes chips from the cutting area, avoiding clogging problems. The synergistic effect of the longitudinal sliding mechanism 2 and the angle adjustment mechanism 4 ensures that the cooling spray assembly 6 and the chip removal assembly 7 can follow the tool position changes in real time, improving the adaptability and flexibility of the equipment. Furthermore, the protective cover design effectively protects the transmission components and extends the service life of the equipment.

[0039] Through the specific embodiments described above, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.

Adjust the base (1) to a horizontal state using a level. 1.3 Start the longitudinal motor (204) of the longitudinal sliding device (2) to drive the screw shaft (203) to rotate, drive the connecting slider (205) to move along the guide rail (201), adjust the fixed bracket (3) to a suitable height, and make the close bracket (5) initially close to the workpiece processing area; Step 2: Precisely adjust the angle and position close to the bracket. 2.1 Start the drive motor (404) of the angle adjustment component (4), drive the gear (402) to mesh with the arc rack (403) to drive the bracket (5) to rotate around the bearing seat (401) and adjust the parallelism between its bottom surface and the workpiece processing surface; 2.2 After the adjustment is completed, restart the longitudinal sliding device (2) and fine-tune the height of the fixed bracket (3); Step 3: Deployment and cooling operation of the cooling jet assembly 3.1 Start the transverse drive screw mechanism (601) of the cooling spray assembly (6), drive the slider (6011) to move the L-shaped mounting base (602) laterally, and adjust the atomizing nozzle (604) to be directly above the workpiece cutting area; 3.2 Start the rotating motor (607), drive the rotating tube (603) to rotate through the transmission of bevel gear one (605) and bevel gear two (606), adjust the spray angle of the atomizing nozzle (604) to be perpendicular to the cutting edge, and ensure that the coolant evenly covers the cutting area; 3.3 Connect an external coolant pump and start the pumping system. The coolant enters the rotating tube (603) through the coolant inlet pipe and is sprayed out by the atomizing nozzle (604) to cool the cutting area. Step 4: Deployment and operation of the chip removal components 4.1 Start the drive screw (703) of the chip removal assembly (7) to drive the sliding seat (702) to move along the sliding frame (701) and adjust the high pressure nozzle (705) to be directly above the cutting area; 4.2 Adjust the hinge angle of the high-pressure nozzle (705) so that its spray direction forms an angle of 30°~45° with the workpiece surface; 4.3 Connect an external high-pressure water source or compressed air source, start the pumping system, and the high-pressure medium is ejected at high speed through the high-pressure nozzle (705) to flush the chips accumulated in the cutting area to the machine tool chip discharge groove. 4.4 The transmission screw (703) drives the sliding seat (702) to reciprocate along the sliding frame (701), and synchronously adjusts the position of the high-pressure nozzle (705) to perform multi-angle chip removal; Step 5: Coordinated operation of cooling and chip removal 5.1 The cooling spray assembly (6) and the chip removal assembly (7) work alternately: During the cutting process, the cooling spray assembly (6) continuously provides coolant; during the cutting gap, the chip removal assembly (7) starts chip removal; 5.2 For deep cavity machining, the height of the close-fitting bracket (5) is adjusted by the longitudinal sliding device (2) so that the atomizing nozzle (604) and the high-pressure nozzle (705) are aligned with the cavity to complete cooling and chip removal respectively; 5.3 Monitor the status of the cutting area in real time. If chips accumulate, start the chip removal component (7) to clean them first, and then restore cooling.
