Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, specifically to a CNC high-speed milling machine tool for processing aerospace parts. Background Technology

[0002] A milling machine tool is a metal processing device that uses a milling cutter to cut workpieces. It is mainly supported by basic components such as the bed and worktable, and equipped with milling cutters, tool holders and corresponding clamping devices for cutting operations. It is automatically controlled by a CNC system and an operation panel. It can be used to process various complex-shaped parts such as planes, grooves, gears, and cams, and is widely used in many industries such as mechanical manufacturing.

[0003] Machine tools are frequently used in the production and processing of aerospace components. A search revealed Chinese patent application CN202311056793.4, which relates to a high-precision high-speed milling machine tool for aero-engine blades, belonging to the field of aero-engine blade processing technology. This high-precision high-speed milling machine tool for aero-engine blades includes a left headstock and a right headstock. Both the left and right headstocks are rotatably mounted with a rotating shaft. Each rotating shaft has a rotating plate, and mounting blocks are slidably mounted on the rotating plate. The sliding direction of the mounting blocks is perpendicular to the rotation axis of the rotating shaft. A clamping block is rotatably mounted on the mounting block, and the rotation axis of the clamping block is parallel to the rotation axis of the rotating shaft. The clamping block is movably mounted with an elastic plate for clamping the workpiece. The rotating plate has a first sliding member for driving the two opposing mounting blocks closer together or further apart. The clamping block has an adjustment component for adjusting the curvature of the elastic plate. This application facilitates clamping workpieces of different shapes and, to a certain extent, ensures milling accuracy.

[0004] The above technical solutions still have shortcomings:

[0005] In high-speed milling of aerospace components, the high-speed rotating cutting tool and the workpiece undergo intense friction and cutting, generating a large amount of high-temperature metal chips. The machine tool lacks effective measures to prevent chip splashing, causing these chips to fly everywhere. On the one hand, the splashing chips may pose a threat to the personal safety of operators, such as burns and punctures; on the other hand, the chips scattered in the work area increase the difficulty of cleaning, affecting the cleanliness of the working environment and production efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4 This utility model provides a technical solution:

[0032] A CNC high-speed milling machine tool for machining aerospace parts includes:

[0033] Main structure; The main structure includes a machine base 1, a feeding mechanism 2 and a fixing mechanism 3. The feeding mechanism 2 is slidably installed at one end of the base via a guide rail. The feeding mechanism 2 is used to feed the tool toward the fixing mechanism 3. A housing is installed at the other end of the base. An operation panel 4 is installed on one side of the housing. The fixing mechanism 3 is installed on one side of the housing to fix the workpiece.

[0034] The machine base 1 serves as the basic support structure for the entire machine tool, providing a stable mounting platform. The feed mechanism 2 slides on one end of the machine base 1 via guide rails, enabling precise control of the tool's movement towards the fixing mechanism 3, thus achieving milling machining of the workpiece fixed on the fixing mechanism 3. The machine housing is installed at the other end of the machine base 1. The operation panel 4 on one side is used by the operator to input commands and control the machine tool's operation; the fixing mechanism 3 on the other side firmly fixes the workpiece, ensuring the workpiece's position remains stable during machining.

[0035] Please see Figure 1-2 :

[0036] It also includes a splash guard mechanism to prevent debris from flying; the splash guard mechanism includes two sets of slide rails 7 and a cover 8 symmetrically installed on the machine base 1. The cover 8 is slidably installed on the slide rails 7. The cover 8 is a transparent PVC material integrally molded arch structure. A handle 9 is provided on one side of the cover 8 for adjusting the position of the cover 8.

[0037] Two sets of slide rails 7 are symmetrically installed on the machine base 1, and the cover 8 can slide flexibly through the slide rails 7. During processing, the one-piece molded transparent PVC arched cover 8 can block the flying debris generated by the high-speed rotating tool cutting the workpiece. The operator can adjust the position of the cover 8 on the slide rails 7 using the handle 9 on one side of the cover 8 according to processing requirements and observation needs.

[0038] This design effectively prevents hot metal shavings from splashing onto the machine tool, ensuring operator safety. It also prevents shavings from scattering in the work area, reducing cleaning difficulty, maintaining a clean working environment, minimizing the risk of production interruptions due to shavings, and improving production efficiency. The transparent material also allows operators to easily observe the processing progress.

[0039] Please see Figure 3-5 :

[0040] It also includes a collection mechanism for collecting debris, which includes a collection port 5 on the base and a pull-out collection hopper 6 located below the collection port 5. The collection port 5 has a conical design that is wider at the top and narrower at the bottom. Two sets of slide rails 7 are located on both sides of the collection port 5, and the lower ends of the inner walls on both sides of the cover 8 are provided with ramps to guide the debris into the collection port 5.

[0041] The machine base 1 has a collection port 5 with a cone-shaped design that is wider at the top and narrower at the bottom, which facilitates the collection of debris into the collection hopper 6 below. The collection hopper 6 can be pulled out for easy cleaning of the collected debris. The lower ends of the inner walls on both sides of the casing 8 are provided with ramps, which guide the debris that splashes onto the inner walls of the casing 8 to slide down the ramps to the collection port 5 and then into the collection hopper 6.

[0042] This design enables efficient collection of chips generated during processing, reducing chip accumulation inside the machine tool and preventing it from affecting normal machine operation. It also facilitates subsequent centralized processing of chips, further improving the cleanliness of the working environment and production efficiency.

[0043] Please see Figure 1-2 :

[0044] It also includes a cooling mechanism for cooling the cutting tool. The cooling mechanism includes a cooling pipe 16 fixed to the top of the housing 8 and a branch pipe 17 at the lower end of the cooling pipe 16. Multiple sets of nozzles 18 are evenly distributed at the bottom of the branch pipe 17. The cooling pipe 16 is sprayed with coolant drawn from the cooling tank by the pump body for cooling.

[0045] During the processing, the operator moves the cover 8 to the area where the workpiece and the tool come into contact. While preventing debris from splashing, the coolant is drawn from the cooling tank by the pump and delivered to the cooling pipe 16 fixed on the top of the cover 8. The coolant is then sprayed onto the tool through the branch pipe 17 at the lower end of the cooling pipe 16 and multiple sets of nozzles 18 evenly distributed at the bottom, so as to cool down the tool that generates high temperature from high-speed rotation.

[0046] This design reduces the temperature of the cutting tool during milling, reduces tool wear, increases tool life, and ensures machining accuracy. At the same time, the coolant also helps to flush away some of the chips and assists the collection mechanism, further ensuring the smooth progress of the machining process.

[0047] In addition, please see Figure 5 :

[0048] The collection hopper 6 has a support frame 19 inside, and a mesh plate 20 is placed on the support frame 19. The mesh plate 20 is used to separate debris and coolant for classified recycling.

[0049] A support frame 19 is installed inside the collection hopper 6, and a screen plate 20 is placed on the support frame 19. When coolant containing debris falls into the collection hopper 6, the screen plate 20 filters it. The coolant flows through the mesh of the screen plate 20 to the bottom of the collection hopper 6, while the debris is intercepted on the screen plate 20, thus achieving the separate recycling of debris and coolant.

[0050] This design facilitates the separate processing of coolant and debris. Coolant can be recycled and reused, while debris can be collected and recycled in a centralized manner, improving resource utilization and reducing waste. At the same time, it avoids the difficulty of subsequent processing caused by the mixing of debris and coolant.

[0051] Please see Figure 4 and Figure 6 :

[0052] It also includes an anti-collision mechanism, which includes a stop block 10 and a buffer block 11 located at both ends of the slide rail 7. The buffer block 11 is slidably mounted on the slide rail 7 and is located on one side of the stop block 10. A connecting rod 12 is provided on one side of the buffer block 11. The connecting rod 12 is slidably inserted into the stop block 10 and a limit block 15 is provided at the end of the connecting rod 12. Two sets of washers 13 are slidably sleeved on the connecting rod 12 between the stop block 10 and the buffer block 11, and a compression spring 14 is slidably sleeved on the connecting rod 12 between the two sets of washers 13.

[0053] Stops 10 are provided at both ends of the slide rail 7, and buffer blocks 11 can slide on the slide rail 7 and are located on one side of the stop blocks 10. When the cover 8 slides to the extreme positions at both ends of the slide rail 7, it will impact the buffer blocks 11. The buffer blocks 11 are pushed by the force to push the connecting rod 12 to slide towards the stop blocks 10, and the limiting block 15 on the connecting rod 12 prevents it from falling out. At this time, the compression spring 14 is compressed by the washer 13 on the connecting rod 12 and contracts, absorbing and buffering the impact force, reducing the impact force generated by the direct collision between the cover 8 and the stop blocks 10.

[0054] This design protects the casing 8 and slide rail 7 in the splash-proof mechanism from damage due to excessive impact, extends the service life of related components, ensures the stable and reliable operation of the splash-proof mechanism, reduces maintenance time and costs caused by component damage, and indirectly improves production efficiency.

[0055] Both washer 13 and buffer block 11 are made of rubber.

[0056] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
