[0034] like Figures 1-5 As shown, it illustrates a CNC gantry milling machine for machining metallurgical parts, comprising:

[0035] A machining bed 1 is equipped with a milling cutter 2.

[0036] The flushing and cleaning component 3 is mounted on the processing bed 1.

[0037] Drive adjustment component 4, which is mounted on milling cutter 2;

[0038] The flushing and cleaning assembly 3 includes a processing tank 3-1, which is located on the upper surface of the processing bed 1. A processing table 3-2 is provided on the upper end of the processing tank 3-1. A collection tank 3-3 is provided inside the processing table 3-2. A connecting strip 3-4 is provided on the processing bed 1. A swing plate 3-5 is pin-connected to the connecting strip 3-4. A flip plate 3-6 is provided on the swing plate 3-5. The flip plate 3-6 is pin-connected to the swing plate 3-5. An installation block 3-7 is provided on the flip plate 3-6. A high-pressure nozzle 3-8 is inserted into the installation block 3-7. A liquid supply pipe 3-9 is provided at the end of the high-pressure nozzle 3-8.

[0039] The drive adjustment assembly 4 includes a gantry 4-1, which is set on the upper end face of the machining bed 1. A sliding table 4-2 is provided on the gantry 4-1, a limit bar 4-3 is provided on the sliding table 4-2, and a traveling sleeve 4-4 is fitted on the sliding table 4-2.

[0040] In some examples, a machining groove 3-1 is precisely cut on the upper surface of the machining bed 1 to ensure the dimensional accuracy and flatness of the groove wall, thus guaranteeing the stability of the machining table 3-2 after installation. The machining table 3-2 is then installed on the upper end of the machining groove 3-1 and secured reliably using bolts or welding to ensure a tight fit between the machining table 3-2 and the machining groove 3-1, preventing shaking during machining. A collection groove 3-3 is machined inside the machining table 3-2. The shape and size of the collection groove 3-3 are determined based on the production process during metallurgical parts processing. The design considers the amount of debris and coolant, typically employing a rectangular groove with a slight slope at the bottom to facilitate the collection of debris and coolant in a specific direction. Installation of connecting strip 3-4, swing plate 3-5, and tilting plate 3-6: Connecting strip 3-4 is mounted on machining bed 1. The connection between connecting strip 3-4 and machining bed 1 can be achieved by bolting or welding. Swing plate 3-5 is connected to connecting strip 3-4 via a pin, ensuring that swing plate 3-5 can rotate flexibly around the pin. The rotation angle range can be adjusted according to actual flushing requirements, generally set between 0 and 90 degrees. Between degrees, the tilting plate 3-6 is connected to the swing plate 3-5 via a pin shaft. The flexibility of the tilting plate 3-6's rotation must also be ensured. The rotation of the tilting plate 3-6 allows for further fine-tuning of the angle of the high-pressure nozzle 3-8 for better alignment with the processing area. Installation of the high-pressure nozzle 3-8 and the supply pipe 3-9: Insert the high-pressure nozzle 3-8 into the mounting block 3-7 on the tilting plate 3-6. An interference fit or threaded connection can be used between the mounting block 3-7 and the high-pressure nozzle 3-8 to ensure a secure installation. Connect the supply pipe 3-9 to the end of the high-pressure nozzle 3-8. The connection between the supply pipe 3-9 and the high-pressure nozzle 3-8 must be airtight, which can be achieved using sealant or gaskets. The other end of the supply pipe 3-9 is connected to the coolant supply system to ensure adequate coolant supply. The high-pressure material is stably and powerfully delivered to the high-pressure nozzle 3-8. The gantry 4-1 is installed on the upper surface of the processing bed 1. The connection between the gantry 4-1 and the processing bed 1 must be firm and vertical. It can be fixed with anchor bolts and calibrated with tools such as a level to ensure that the gantry 4-1 will not shift or shake during processing. A sliding table 4-2 is installed on the gantry 4-1. The sliding table 4-2 and the gantry 4-1 are connected by a guide rail slider to ensure that the sliding table 4-2 can slide smoothly along the gantry 4-1. A limit strip 4-3 is installed on the sliding table 4-2. The function of the limit strip 4-3 is to limit the movement range of the traveling sleeve 4-4 and prevent it from derailing. The connection between the limit strip 4-3 and the sliding table 4-2 can be fixed with bolts to ensure that the limit strip 4-3 is firmly installed.

[0041] like Figures 1-5 As shown in the figure, this embodiment proposes that the side wall of the processing bed 1 is provided with a flow guide cavity 3-10, and the end of the flow guide cavity 3-10 is provided with an arc-shaped flow guide groove 3-11.

[0042] In some examples, a flow guide cavity 3-10 is installed on the side wall of the machining bed 1. The connection between the flow guide cavity 3-10 and the machining bed 1 can be achieved by welding or bolting to ensure a good seal at the connection and prevent coolant leakage. An arc-shaped flow guide groove 3-11 is provided at the end of the flow guide cavity 3-10. The design of the arc-shaped flow guide groove 3-11 should ensure that the coolant can be smoothly guided from the flow guide cavity 3-10 into the collection tank 7. The connection between the arc-shaped flow guide groove 3-11 and the flow guide cavity 3-10 should be smooth to avoid any protrusions or depressions that obstruct the flow of coolant.

[0043] For example, such as Figure 5 As shown, a drive motor 4-5 is provided on the walking sleeve 4-4. The output end of the drive motor 4-5 is inserted into the walking sleeve 4-4. A drive wheel 4-6 is provided on the output end of the drive motor 4-5. The drive wheel 4-6 is in contact with the limit strip 4-3.

[0044] In some examples, the traveling sleeve 4-4 is mounted on the sliding table 4-2. The fit between the traveling sleeve 4-4 and the sliding table 4-2 must maintain a certain clearance to ensure that the traveling sleeve 4-4 slides flexibly without excessive wobbling. A drive motor 4-5 is installed on the traveling sleeve 4-4. The installation of the drive motor 4-5 must ensure that its output shaft is coaxial with the central axis of the traveling sleeve 4-4. This can be adjusted using the motor mounting bracket. The output end of the drive motor 4-5 is inserted into the traveling sleeve 4-4, and a drive wheel 4-6 is installed on the output end. The drive wheel 4-6 is in contact with the limit strip 4-3. The drive motor 4-5 drives the drive wheel 4-6 to rotate, and the drive wheel 4-6 rolls on the limit strip 4-3, thereby realizing the movement of the traveling sleeve 4-4 along the sliding table 4-2.

[0045] For example, such as Figure 1 As shown, the lower end face of the processing bed 1 is provided with a support leg 5, and a mounting sleeve 6 is fitted on the support leg 5. A collection box 7 is provided on the side wall of the mounting sleeve 6, and the position of the collection box 7 corresponds to that of the arc-shaped guide channel 3-11.

[0046] In some examples, a support leg 5 is installed on the lower end face of the machining bed 1. The connection between the support leg 5 and the machining bed 1 should be firm, which can be achieved by welding or bolting. A mounting sleeve 6 is fitted on the support leg 5. The mounting sleeve 6 and the support leg 5 can be fixed by interference fit or welding. A collection box 7 is installed on the side wall of the mounting sleeve 6. The position of the collection box 7 and the arc-shaped guide channel 3-11 should correspond precisely to ensure that the coolant and debris flowing out of the arc-shaped guide channel 3-11 can fall accurately into the collection box 7. The connection between the collection box 7 and the mounting sleeve 6 can be bolted to facilitate the disassembly and cleaning of the collection box 7.

[0047] For example, such as Figure 4 As shown, the milling cutter 2 is fixedly mounted by a rotatable and telescopic tool holder, and the milling cutter 2 is located on the lower end face of the traveling sleeve 4-4.

[0048] In some examples, the milling cutter 2 is fixedly mounted on the lower end face of the traveling sleeve 4-4 by a rotatable and telescopic tool holder. The connection between the tool holder and the traveling sleeve 4-4 must be secure and enable the milling cutter 2 to rotate and extend. The rotation of the tool holder can be driven by a motor, and the extension function can be achieved by a lead screw and nut mechanism or a hydraulic or pneumatic telescopic rod. The installation of the milling cutter 2 must ensure its installation accuracy on the tool holder, ensuring that the central axis of the milling cutter 2 coincides with the rotation axis of the tool holder, and avoiding the milling cutter 2 from wobble during the machining process.

[0049] For example, such as Figure 3 As shown, there are several high-pressure nozzles 3-8 and collection tanks 3-3, with multiple high-pressure nozzles 3-8 embedded inside the collection tanks 3-3.

[0050] In some examples, the number of high-pressure nozzles 3-8 and collection tanks 3-3 is determined according to processing requirements. Generally, when processing metallurgical parts with complex shapes, the number of high-pressure nozzles 3-8 can be appropriately increased to ensure the flushing effect. Multiple high-pressure nozzles 3-8 are evenly embedded inside the collection tanks 3-3. The arrangement of high-pressure nozzles 3-8 should take into account the ability to fully cover the processing area to ensure that the debris and coolant generated during the processing can be flushed and collected in a timely manner.

[0051] For example, such as Figure 3 As shown, a movable shaft 8 is provided on the flip plate 3-6, and the movable shaft 8 is connected to the swing plate 3-5 by a pin.

[0052] In some examples, a movable shaft 8 is installed on the flip plate 3-6. The connection between the movable shaft 8 and the flip plate 3-6 can be achieved by welding or interference fit. The movable shaft 8 is connected to the swing plate 3-5 by a pin. The installation of the movable shaft 8 must ensure the fitting accuracy between it and the pin to ensure the flexibility and stability of the flip plate 3-6 when rotating around the pin.

[0053] In use, the CNC system controls the rotatable and telescopic tool post to drive the milling cutter 2 to rotate and feed. The rotation of the tool post provides cutting power for the milling cutter 2, while the telescopic movement controls the position of the milling cutter 2 in the vertical direction to achieve the machining of different parts of the metallurgical parts. The traveling sleeve 4-4 moves along the sliding table 4-2 on the gantry 4-1 under the action of the drive adjustment component 4, thereby driving the milling cutter 2 to move in the horizontal direction to achieve the machining of the plane or contour of the metallurgical parts. By precisely controlling the speed, position and trajectory of these movements through the CNC system, the metallurgical parts can be precisely machined according to the preset program.

[0054] Flushing and cleaning principle: When metallurgical parts are being processed, the flushing and cleaning component 3 starts to work. Coolant is delivered to the high-pressure nozzle 3-8 through the supply pipe 3-9. The high-pressure nozzle 3-8 sprays the coolant in the form of high-pressure jets to flush the processing parts. Since the tilting plate 3-6 and the swing plate 3-5 are connected by a pin, and the tilting plate 3-6 is provided with a movable shaft 8 connected to the swing plate 3-5 by the pin, the angle of the tilting plate 3-6 and the swing plate 3-5 can be adjusted so that the high-pressure nozzle 3-8 can be aimed at different processing parts to achieve all-round flushing. The debris and coolant flushed off will fall into the collection tank 3-3 inside the processing table 3-2, and then flow along the slope of the collection tank 3-3 to the guide cavity 3-10 on the side wall of the processing bed 1. Then, it flows into the collection box 7 through the arc-shaped guide groove 3-11 at the end of the guide cavity 3-10, thereby collecting and cleaning the debris and coolant generated during the processing and keeping the processing environment clean.

[0055] Drive adjustment principle: After the drive motor 4-5 starts, the drive wheel 4-6 at its output end rolls on the limit bar 4-3. Since the limit bar 4-3 is installed on the sliding table 4-2, and the traveling sleeve 4-4 is fitted on the sliding table 4-2, and the drive wheel 4-6 is in contact with the limit bar 4-3, the rotation of the drive wheel 4-6 will drive the traveling sleeve 4-4 to move along the sliding table 4-2. The gantry 4-1 is fixed on the machining bed 1, and the sliding table 4-2 is installed on the gantry 4-1. This realizes the horizontal movement of the traveling sleeve 4-4 on the gantry 4-1, thereby driving the milling cutter 2 installed on the lower end face of the traveling sleeve 4-4 to adjust its position in the horizontal direction to meet the needs of different machining positions. At the same time, the sliding table 4-2 and the gantry 4-1 are connected by a guide rail slider, which ensures the smoothness and stability of the movement of the sliding table 4-2. The limit bar 4-3 restricts the movement range of the traveling sleeve 4-4 to prevent it from derailing, ensuring the accuracy and reliability of the entire drive adjustment process.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
