Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, and in particular relates to a CNC drilling, tapping and milling combination machine tool. Background Technology

[0002] The CNC drilling, tapping and milling combination machine tool is a CNC machining equipment that integrates multiple cutting processes such as drilling, tapping and milling. It can complete multiple continuous processing processes in one workpiece clamping and is widely used in the processing of small and medium-sized hardware parts, automotive parts, pneumatic components and other fields.

[0003] Existing workpiece surface cleaning methods mostly involve airflow blowing. However, it is difficult to effectively clean embedded ferromagnetic debris in hard-to-reach areas such as grooves, threaded holes, and gaps on the workpiece surface. The remaining debris is easily pressed into the workpiece surface by the cutting tool during subsequent processing, causing surface scratches, pits, and other quality defects. At the same time, the static electricity generated by friction during processing will attract fine metal dust, further increasing the cleaning difficulty. Simple mechanical cleaning is difficult to achieve the ideal cleaning effect.

[0004] In addition, the rust prevention and passivation treatment of workpieces between processes often requires additional workstations or machine shutdowns, which is disconnected from the cleaning process, reduces the overall processing efficiency, and is difficult to adapt to the compact layout of small desktop drilling and milling machines.

[0005] Therefore, we propose a CNC drilling and milling combination machine tool to solve the above problems. Summary of the Invention

[0022] 2.

[0023] 3. By integrating a floating coating component into the cleaning component, rust prevention or passivation coating treatment of the workpiece surface can be completed simultaneously with the cleaning operation, without the need for additional processes and stations, thus improving processing efficiency;

[0024] 4. By combining with the ion wind structure, static electricity on the workpiece surface can be neutralized, reducing the adsorption of fine dust.

[0048] Each of the two sets of liquid storage tanks 806 is equipped with a liquid pump 808 on one side of its outer surface.

[0049] A second control power supply 7 is fixedly connected to one side of the outer surface of the movable plate 5. The second control power supply 7 is electrically connected to the driving components of the first electromagnetic cone 702, the second electromagnetic cone 705, and the brush 704.

[0050] The operating principle of the present invention is described as follows:

[0051] The working process and principle of chip collection:

[0052] When the machine tool 1 performs drilling and milling, the moving frame 101 drives the machining head 102 to move along the set path, the fixed plate 103 moves synchronously with the moving frame 101, and the two sets of first cylinders 201 drive the collection box 2 to be suspended on the side and rear of the machining area, moving synchronously with the machining head 102 to receive the chips generated during machining.

[0053] The first control power supply 3 controls the polarity of the first electromagnet 301 and the second electromagnet 302, as well as the working state of the third electromagnet 303, based on the current machining process signal of the machine tool 1. The third electromagnet 303 is in the normally open state, generating an attractive force to the ferromagnetic chips, assisting the chips to smoothly enter the collection box 2 and reducing chip splashing. When the machine tool 1 performs a drilling process, the first control power supply 3 supplies current in the corresponding direction to the first electromagnets 301 on both sides, causing the first electromagnets 301 to generate a magnetic force that attracts the second electromagnets 302 on both sides of the baffle 203. The magnetic force causes the second electromagnets 302 to deflect towards the first electromagnets 301, and then drives the baffle 203 to rotate to the corresponding angle inside the collection box 2 through the rotating rod 202, dividing the internal cavity of the collection box 2 into a long chip collection area. The long, curled chips generated during drilling are guided along the baffle 203 into this area for collection. When machine tool 1 switches to tapping or milling, the first control power supply 3 switches the current direction of the first electromagnet 301, causing a repulsive force between the first electromagnet 301 and the second electromagnet 302. Combined with the reset force of the torsion spring 204, the baffle 203 is rotated in the opposite direction to another angle, switching to the chip collection area. The fine chips generated by tapping and milling are guided into the corresponding area for collection, thereby realizing the separate storage of chips of different shapes.

[0054] A torsion spring 204 is sleeved on the rotating rod 202. It can provide a reset torque when the electromagnetic force disappears, maintaining the initial position of the baffle 203. At the same time, it can provide a buffer when the baffle 203 rotates, reducing rotational impact. The drain hole at the bottom of the collection box 2 can allow the cutting fluid mixed in with the chips to seep out, reducing the accumulation of liquid in the chamber and slowing down the chip corrosion rate.

[0055] Workpiece surface cleaning process and principle:

[0056] When machine tool 1 is switching tools or in the intermittent stage of machining, drive motor 401 starts, and the output torque is transmitted to drive screw 402. Drive screw 402 rotates, causing threaded block 404 to move axially, which in turn causes moving plate 5 to translate along the length of fixed chamber 4, cleaning the surface of the workpiece below. Limiting rod 403 is inserted inside threaded block 404 to guide and radially limit the movement of threaded block 404, ensuring the stability of moving plate 5 during translation and preventing deflection and wobbling.

[0057] The second control power supply 7 controls the excitation state of the first electromagnetic cone 702 and the second electromagnetic cone 705. Along the traveling direction of the moving plate 5, the first electromagnetic cone 702 at the front is set to a repulsive working mode. The third cylinder 701 drives the first electromagnetic cone 702 to adjust to a height close to the workpiece surface. The magnetic field generated by the repulsion acts on the ferromagnetic debris on the workpiece surface, pushing out debris embedded in grooves, threaded holes, gaps, and other dead corners, while simultaneously breaking up clustered chip clumps for easier subsequent cleaning. The brush 704, located in the middle, is driven down to the workpiece surface by the fourth cylinder 703. As the moving plate 5 moves, it loosens the surface debris and peels it off the workpiece surface. The second electromagnetic cone 705 at the rear is set to an attractive working mode, attracting and gathering dispersed ferromagnetic debris, collecting the loosened debris and preventing secondary scattering.

[0058] At the same time, the ion blower 901 starts to generate charged ion airflow. The airflow is delivered to the ion bar 9 through the air guide pipe 902. The ion bar 9 blows the ion airflow evenly onto the surface of the workpiece, neutralizes the static electricity generated on the surface of the workpiece due to processing friction, eliminates the adsorption effect of static electricity on fine metal dust, and causes the fine dust to be removed from the surface of the workpiece with the airflow, thus helping to improve the cleaning effect.

[0059] Synchronous coating process and principle:

[0060] The coating assembly moves synchronously with the moving plate 5, completing surface coating in the latter half of the cleaning operation. The storage tank 806 contains rust-preventing or passivating media, and the replenishment port 807 is used to replenish the media in the storage tank 806. The pump 808 extracts the media from the storage tank 806 and delivers it through a hose 809 to the hollow rod 801. The hollow rod 801 has permeation holes in its wall, through which the media evenly wets the flexible sponge coating roller 8.

[0061] The support plate 803 is fixed on the movable plate 5, and the rotating column 804 is rotatably embedded in the support plate 803. A spring 805 is sleeved on the rotating column 804, providing elastic restoring force to the connecting plate 802, allowing the connecting plate 802 to swing slightly around the rotating column 804, forming a floating support structure. This floating structure drives the hollow rod 801 to adaptively conform to the slight undulations of the workpiece surface with the flexible sponge coating roller 8, ensuring uniform contact pressure between the flexible sponge coating roller 8 and the workpiece surface, and avoiding uneven coating thickness caused by uneven workpiece surface. As the flexible sponge coating roller 8 rolls along the workpiece surface, it uniformly coats the impregnated medium onto the workpiece surface, forming a thin protective film, completing the rust prevention or passivation treatment between processes.

[0062] Positioning and surface inspection working process and principle:

[0063] During the translation of the moving plate 5, the two sets of second cylinders 602 respectively drive the infrared sensor 6 and the infrared receiver 601 to adjust to the corresponding height. The infrared sensor 6 emits infrared signals and the infrared receiver 601 receives reflected signals, thereby detecting the walking position of the moving plate 5 and the edge contour of the workpiece, realizing the positioning of the start and end points of the cleaning stroke, and preventing the moving plate 5 from exceeding the stroke range.

[0064] The industrial camera 603 moves synchronously with the moving plate 5, with its lens vertically facing the workpiece surface. During the cleaning operation, it continuously collects image information of the workpiece surface, which can identify the state of surface debris residue, hole defects, surface scratches, etc., and feeds the information back to the machine tool control system, so as to adjust the cleaning parameters or processing program in a timely manner and reduce the generation of defective products.

[0065] Example 1:

[0066] When machine tool 1 is running, the moving frame 101 drives the machining head 102 to perform drilling, tapping, and milling operations sequentially according to the machining program. The fixed plate 103 moves synchronously with the moving frame 101. The collecting box 2 is adjusted to a suitable height by the first cylinder 201, moves with the machining head 102, and collects the chips. The reason for setting the electromagnetic drive baffle 203 is that, compared with the traditional mechanical linkage chip-distributing structure, the electromagnetic drive has a faster response speed, which can match the rapid switching of drilling, tapping, and milling operations and reduce the chip mixing problem caused by switching delay.

[0067] The first control power supply 3 reads the machine tool's process signals in real time. When drilling is performed, it controls the first electromagnet 301 and the second electromagnet 302 to be in an attractive state, causing the baffle 203 to deflect to the long chip collection position. The long, curled chips generated during drilling slide into the long chip cavity along the baffle 203. The third electromagnet 303 remains in a normally open attracting state, assisting in pulling the chips into the box and reducing the ejection of long chips. When the process is switched to tapping or milling, the first control power supply 3 switches the polarity of the first electromagnet 301. The electromagnetic repulsion, combined with the elasticity of the torsion spring 204, causes the baffle 203 to quickly switch to the chip collection position. Fine chips are guided into the chip cavity, realizing the chip storage according to shape, which is convenient for subsequent classification and recycling.

[0068] During the tool change interval, the drive motor 401 drives the moving plate 5 to move horizontally via the drive screw 402, initiating the cleaning operation. A tiered magnetic attraction structure is used, with the front first electromagnetic cone 702 repelling and the rear second electromagnetic cone 705 attracting. This is because a single magnetic attraction structure can only attract surface debris and cannot clean the dead corners. The front repulsive magnetic field pushes outwards the ferromagnetic debris embedded in the dead corners, the middle brush 704 loosens the surface debris, and the rear attracting magnetic field gathers and attracts the dispersed debris. The three work together to form a tiered cleaning process of pushing out, loosening, and attracting, improving the cleaning effect in dead corner areas. The third cylinder 701 and the fourth cylinder 703 can adjust the height of the electromagnetic cones and brushes respectively, adapting to workpieces of different thicknesses. During the cleaning process, the ion blower 901 blows ion air onto the workpiece surface via the ion air bar 9, neutralizing static electricity on the workpiece surface, reducing the adsorption of fine dust, and further improving the cleaning effect.

[0069] Example 2:

[0070] The coating assembly is integrated on the moving plate 5 and moves synchronously with the cleaning assembly. No additional coating station is required, allowing for full utilization of the cleaning intervals during tool changes to complete the coating operation and improve processing efficiency. The floating flexible sponge coating roller 8 is designed because rigid coating structures are prone to uneven coating or scratching of the workpiece when there are slight undulations or steps on the workpiece surface. The floating support structure formed by the rotating column 804 and spring 805 drives the connecting plate 802 to swing slightly, allowing the flexible sponge coating roller 8 to adaptively conform to the workpiece surface, ensuring uniform coating pressure and improving film consistency.

[0071] During the cleaning process, the pump 808 delivers the anti-rust medium from the storage tank 806 to the hollow rod 801 via the hose 809. The medium penetrates into the flexible sponge coating roller 8. As the coating roller rolls with the moving plate 5, it evenly coats the cleaned workpiece surface with the anti-rust medium, forming a thin anti-rust film to prevent rust from recurring during process transitions. The replenishment port 807 at the top of the storage tank 806 allows for periodic replenishment of the medium, maintaining the continuity of the coating operation.

[0072] Simultaneously, the industrial camera 603 moves synchronously with the moving plate 5 to acquire images of the cleaned and coated workpiece surface. The reason for setting up a synchronous detection structure is to fully utilize the cleaning travel distance, completing the workpiece surface condition screening without additional inspection time. This allows for timely identification of defects such as residual debris, surface scratches, and abnormal hole positions. Feedback to the machine tool control system enables timely adjustment of process parameters, reducing the defect rate. The infrared sensor 6 and infrared receiver 601 work together to achieve the travel positioning of the moving plate 5, ensuring that the cleaning and coating area accurately corresponds to the workpiece processing area, avoiding unnecessary work.
