Description

Technical Field

[0001] This application relates to the field of propeller machining equipment technology, and in particular to an integrated machining device suitable for large marine propellers. Background Technology

[0002] Large marine propellers are the core components of a ship's propulsion system. Their manufacturing precision directly affects the ship's propulsion efficiency, vibration and noise levels, and navigation safety. Propellers are mostly multi-bladed complex spatial curved surface structures made of difficult-to-machine materials such as nickel-aluminum bronze and stainless steel.

[0003] Currently, the processing of large marine propellers typically involves a combination of machine processing and manual grinding. The final smoothing and precision calibration of the transition joints heavily relies on the skill level of senior technicians. The grinding cycle for a single propeller is long, and there are issues such as inconsistent grinding dimensions and high safety risks. In addition, the harsh grinding environment with a lot of dust poses a significant threat to the physical and mental health of operators, leading to difficulties in recruiting workers. Furthermore, some companies use robots for grinding, but due to the lack of rigidity of robots and their small grinding volume, the grinding cycle is long. Moreover, when changing the type of workpiece, reprogramming is required, which consumes a lot of programming time and further affects the processing time of the parts.

[0004] Meanwhile, when machining propellers, workpiece clamping is the primary factor that determines the success or failure of the machining process. In the existing technology, when machining and clamping large propeller hubs, the propeller is fixed by a chuck. However, in order to ensure clamping force and avoid propeller deviation, the outer wall of the propeller is easily damaged by clamping.

[0005] In other words, existing technologies have the following technical problems: conventional propeller processing methods rely on manual labor, resulting in low efficiency and a tendency for misalignment and damage during clamping. Therefore, to address these issues, an integrated processing device suitable for large marine propellers is proposed. Summary of the Invention

A rotating mechanism 206 is fixedly installed on one side of the Z-axis moving mechanism 205, and a cutting assembly 3 is fixedly connected to one end of the rotating mechanism 206 to drive the cutting tool 302 to achieve multi-axis linkage in order to complete the milling of the propeller 6.

The propeller fixing assembly 5 consists of a rotatable three-jaw chuck 503 and a central support mechanism 504. The central support mechanism 504 is used to provide radial support from the inner hole of the propeller hub 6, forming a clamping force system that works together with the external clamping of the three-jaw chuck 503 to significantly enhance the overall rigidity of the workpiece and suppress the deformation of the thin-walled hub caused by the external clamping force.

[0023] This application achieves automated operation through the integration of a multi-axis linkage machining adjustment component 2 and a 3D scanner 304, enabling automatic path planning. This significantly reduces reliance on skilled technicians and greatly improves processing efficiency and product consistency. In addition, this solution also includes a propeller fixing component 5. Through the coordinated design of a rotatable three-jaw chuck 503 and a central support mechanism 504, it can automatically and reliably support the workpiece from both inside and outside during clamping. This provides strong clamping rigidity while effectively suppressing deformation of the thin-walled propeller hub caused by clamping force.

The first screw 2023 passes through the translation support 2021 and is threadedly engaged with the translation support 2021. A first control motor 2025 is fixedly installed on the side wall of the fixed side plate 2024. The end of the output shaft of the first control motor 2025 is fixedly connected to one end of the first screw 2023. Through this technical solution, the first control motor 2025 drives the first screw 2023 to rotate, which drives the translation support 2021 to move precisely along the guide rail 2022, providing the tool with a large stroke feed capability in the X-axis direction.

[0026] Further, see Figure 3 and Figure 4 As shown, a support base 203 is also fixedly connected to the upper surface of the translation support 2021. A Y-axis moving mechanism 204 is provided at one end of the support base 203. Through this technical solution, a Y-axis moving foundation superimposed on the X-axis moving platform is constructed, forming a two-dimensional motion capability on the horizontal plane.

[0027] As a preferred technical solution, please refer to Figure 5 As shown, the Y-axis moving mechanism 204 includes a connecting seat 2041, fixed guide rods 2042, and a driving cylinder 2043. Two fixed guide rods 2042 are fixedly connected to one side of the connecting seat 2041. Both fixed guide rods 2042 pass through the support seat 203 and slide with the support seat 203 to form a high-rigidity sliding pair guide. The driving cylinder 2043 is fixedly installed inside the support seat 203. One end of the driving cylinder 2043 is fixedly connected to the connecting seat 2041. Through this technical solution, the extension and retraction movement of the driving cylinder 2043 can directly and quickly drive the connecting seat 2041 and the Z-axis moving mechanism 205 and the cutting assembly 3 above it to move along the Y-axis direction, which is suitable for working conditions that require rapid positioning or auxiliary cutting.

[0028] In a preferred embodiment of this application, see [reference] Figure 3 and Figure 5As shown, a Z-axis moving mechanism 205 is fixedly installed at one end of the connecting seat 2041.

The second screw 2054 is rotatably connected between the upper and lower walls of the inner cavity of the rectangular fixed shell 2051. The second screw 2054 passes through the Z-axis moving slider 2053 and is connected to the Z-axis moving slider 2053. The rectangular fixed shell 2051 is threaded together with a top cover plate 2052 fixedly connected to the upper end. A second control motor 2055 is fixedly installed on the upper surface of the top cover plate 2052. The output shaft end of the second control motor 2055 is fixedly connected to one end of the second screw 2054. Through this technical solution, the second control motor 2055 drives the second screw 2054 to rotate, thereby controlling the up and down movement of the Z-axis moving slider 2053, thereby driving the cutting component 3 to achieve precise vertical feed and complete the processing of blades at different height positions of the propeller 6.

[0029] Furthermore, in order to enable the cutting tool to flexibly adjust the machining angle to conform to the complex curved surface profile of the propeller 6, see [reference needed].

A cutting assembly 3 is fixedly provided on the rotating table 2065 to drive the cutting tool 302 to rotate around a horizontal axis or a specific axis, thereby increasing a rotational degree of freedom and realizing multi-axis linkage machining.

[0030] The cutting assembly 3 includes a cutting support 301 and a cutting tool 302. The cutting support 301 is fixedly mounted at one end of the rotary table 2065. The cutting tool 302 is rotatably connected to the bottom end of the cutting support 301. A cutting motor 303 is fixedly mounted on the upper surface of the cutting support 301. The output shaft end of the cutting motor 303 is fixedly connected to one end of the cutting tool 302. Through this technical solution, the cutting motor 303 provides the main cutting power to the cutting tool 302, enabling it to rotate at high speed and realize the removal of material from the propeller 6. As a preferred technical solution, in order to achieve in-machine inspection and process quality control, a three-dimensional scanner 304 is also fixedly installed on the side wall of the cutting support 301. Specifically, the optical lens of the three-dimensional scanner 304 faces the workpiece processing area, and can acquire the three-dimensional morphological data of the processing surface online and compare it with the design model to guide the real-time correction of the processing path or to perform final inspection.

[0031] Furthermore, see Figure 6As shown, the fixed base 2061 has an internal cavity. A second connecting rod 2066 is rotatably connected to the internal cavity of the fixed base 2061. One end of the second connecting rod 2066 is fixedly connected to the rotary table 2065 to transmit torque and drive the rotary table 2065 to rotate.

A first connecting rod 2063 is fixedly connected to the end of the output shaft of the rotary control motor 2062. A first bevel gear 2064 is fixedly connected to one end of the first connecting rod 2063. The first bevel gear 2064 and the second bevel gear 2067 mesh with each other. Through this technical solution, the power of the rotary control motor 2062 is transmitted through a pair of orthogonal bevel gears, changing the direction of the torque and ultimately driving the rotary table 2065 and the cutting assembly 3 to achieve angular swing.

[0032] In one specific embodiment of this application, see [reference]. Figure 7 As shown, the auxiliary cutting component 4 is set at the translation support 2021.

The rear end of the movable seat 401 is fixedly connected to one end of the guide rod 404, and the other end of the guide rod 404 is fixedly connected to the movable slider 403.

[0033] Furthermore, in order to achieve control over the position of the auxiliary cutting component 4, see [reference needed].

A bevel gear B407 is fixedly installed at the end of the output shaft of the adjustment motor 408. The bevel gear B407 meshes with the bevel gear A406. Through this technical solution, the adjustment motor 408 drives the control screw 405 to rotate through a pair of bevel gears, thereby driving the movable slider 403, guide rod 404 and movable seat 401 to move linearly along the guide groove, thereby adjusting the position of the cutting part 402 relative to the workpiece.

[0034] As a preferred technical solution, please refer to Figure 9As shown, the cutting unit 402 includes a cutting circular blade 4021 and a rotating shaft 4022.

An inner cavity is provided inside the movable base 401, and a second rotating wheel 4024 is rotatably connected to the inner cavity of the movable base 401. The second rotating wheel 4024 is sleeved with the first rotating wheel 4023. A drive motor 4026 is fixedly installed on the upper surface of the movable seat 401 via a connecting belt 4025. The output shaft of the drive motor 4026 extends into the inner cavity of the movable seat 401, and the output shaft of the drive motor 4026 is fixedly connected to a second rotating wheel 4024. Through this technical solution, the drive motor 4026 transmits power to the rotating shaft 4022 via the connecting belt 4025, driving the cutting circular blade 4021 to rotate at high speed, thereby achieving effective cutting of specific parts of the workpiece.

[0035] In a preferred embodiment of this application, see [reference]. Figure 10 and Figure 11 As shown, the propeller fixing assembly 5 also includes a support base 501 and a turntable 502. The support base 501 is fixedly disposed on the upper surface of the mounting base 1. The upper end of the support base 501 is rotatably connected to the turntable 502. The upper end of the turntable 502 is fixed with a three-jaw chuck 503. The jaws 5031 on the three-jaw chuck 503 are used to radially clamp the outer wall of the propeller 6.

[0036] Preferably, in order to drive the workpiece to rotate and achieve indexing machining of blades at different angles, see [reference needed]. Figure 12 and Figure 13 As shown, the support base 501 has an internal cavity, and a rotary spindle 510 is rotatably connected within the cavity. One end of the rotary spindle 510 is fixedly connected to the bottom surface of the turntable 502. A rotary drive motor 509 is also provided on the side wall of the support base 501. One end of a drive shaft 507 is fixedly connected to the output shaft of the rotary drive motor 509, and the other end of the drive shaft 507 extends into the internal cavity of the support base 501. A drive gear 508 is fixedly installed at one end of the drive shaft 507, and a driven gear 506 is fixedly installed at the bottom end of the rotary spindle 510. The drive gear 508 and the driven gear 506 mesh with each other. Through this technical solution, the power of the rotary drive motor 509 is transmitted to the rotary spindle 510 through a pair of meshing gears, thereby driving the turntable 502, the three-jaw chuck 503, and the workpiece as a whole to perform circumferential indexing motion, so that each blade can enter the processing position in sequence.

[0037] In one specific embodiment of this application, see [reference]. Figure 13 and Figure 14As shown, a central support mechanism 504 is provided at the center of the three-jaw chuck 503. The central support mechanism 504 is used to adaptively tighten the inner hole of the propeller hub 6 and provide internal support. The central support mechanism 504 includes a vertical rod 5042, a movable rod 5043, and a spreading part. The vertical rod 5042 is located at the center of the three-jaw chuck 503. The movable rod 5043 is slidably arranged in the inner cavity of the vertical rod 5042. Several spreading parts are also provided between the movable rod 5043 and the vertical rod 5042. The spreading parts are arranged in a ring array and are used to synchronously generate radial expansion or contraction movement when the movable rod 5043 moves axially. When the movable rod 5043 moves downward, it pushes the spreading parts to expand outward synchronously, so that the support plate 5047 presses against the inner hole wall of the propeller hub. At the same time, due to the telescopic structure formed between the vertical rod 5042 and the movable rod 5043, it can adapt to propellers 6 with different inner hole depths within a certain range.

[0038] Preferably, the expansion section includes a first support frame 5044, a second support frame 5045, and a support plate 5047. The second support frame 5045 is rotatably connected to the first support frame 5044. A support leg 5046 is also rotatably connected at the connection between the first support frame 5044 and the second support frame 5045. One end of the support leg 5046 is fixedly connected to the support plate 5047. The upper end of the first support frame 5044 is rotatably connected to the moving rod 5043, and the lower end of the second support frame 5045 is rotatably connected to the upright 5042. Through this technical solution, the downward movement of the moving rod 5043 is converted into the radial outward movement of the support leg 5046 and the support plate 5047 through the linkage mechanism formed by the first support frame 5044 and the second support frame 5045. The structure is stable, the expansion force is large, and the multiple expansion sections move synchronously, ensuring the uniformity and coaxiality of the support for the inner hole.

[0039] Furthermore, to achieve automatic linkage between external clamping and internal support, simplify operation, and ensure synchronized clamping forces, refer to... Figure 14 and Figure 15 As shown, a bottom shell 5041 is fixedly connected to the bottom end of the upright 5042. The bottom shell 5041 and the inner cavity of the upright 5042 are interconnected. A drive piston 5048 is slidably arranged in the inner cavity of the upright 5042. The drive piston 5048 is fixedly connected to the bottom end of the moving rod 5043. A support drive mechanism 505 is provided on the jaws 5031 of the three-jaw chuck 503. When the jaws 5031 are in the clamping state, the support drive mechanism 505 is triggered, which drives the central support mechanism 504 to move.

[0040] Furthermore, see Figure 15As shown, the support drive mechanism 505 includes a fixed cylinder 5051 and a movable piston 5053. The fixed cylinder 5051 is fixedly mounted on the gripper 5031. The movable piston 5053 is slidably connected inside the cavity of the fixed cylinder 5051. One end of a connecting hose 5052 is fixedly connected to one side of the cavity of the fixed cylinder 5051. The other end of the connecting hose 5052 extends into the cavity of the bottom shell 5041. One end of a connecting guide rod 5054 is connected to one side of the movable piston 5053. The other end of the connecting guide rod 5054 penetrates the inner wall of the fixed cylinder 5051 and... Extending outwards from the wall, one end of the connecting guide rod 5054 is also fixedly connected to a connecting frame 5055. The connecting frame 5055 is fixedly connected to the outer wall of the three-jaw chuck 503. When the jaws 5031 are in the clamping and moving state, they can drive the fixed cylinder 5051 to move relative to the connecting frame 5055 and the moving piston 5053, thereby squeezing or stretching the fluid in the inner cavity of the fixed cylinder 5051. Then, the pressure change is transmitted to the inner cavity of the bottom shell 5041 through the connecting hose 5052, driving the driving piston 5048 to move up and down, realizing the synchronous action of the internal support.

[0041] As a preferred technical solution, in order to provide a stable, finely adjustable and pressure-transmitting working medium, the inner cavities of the fixed cylinder 5051, the bottom shell 5041, and the upright rod 5042 are filled with hydraulic oil. Through this technical solution, by utilizing the incompressibility of hydraulic oil, the radial clamping displacement of the gripper 5031 can be accurately converted into driving pressure on the central support mechanism 504, thereby realizing the automatic matching and linkage of internal and external clamping forces and ensuring that the workpiece is subjected to uniform force.

[0042] Furthermore, a connecting spring 5057 is provided between the connecting guide rod 5054 and the moving piston 5053. One end of the connecting spring 5057 is fixedly connected to the moving piston 5053, and the other end of the connecting spring 5057 is fixedly connected to a circular plate 5056, which is fixedly connected to one end of the connecting guide rod 5054. The main function of the connecting spring 5057 is to provide the necessary elastic stroke and pressure buffer throughout the entire linkage clamping process. Specifically, when the jaws 5031 of the three-jaw chuck 503 move inward to clamp propellers 6 with different outer diameters, the final radial position of the jaws 5031 is different. This process drives the fixed cylinder 5051 to move, thereby pushing the internal moving piston 5053 to compress or stretch the connecting spring 5057, rather than immediately, rigidly, and equally driving the hydraulic oil flow. The compression or stretching of the connecting spring 5057 absorbs and stores the displacement of the jaws 5031 due to the difference in workpiece size, and converts the mechanical displacement into elastic force.

[0043] Through the above design, it is ensured that the clamping force and the internal support force are not simply rigidly linked, but flexibly coupled through springs. This allows the structure to automatically adapt to fluctuations in workpiece size within a certain range and always maintain a reliable clamping force that is coordinated internally and externally. When the workpiece is released, the compressed or stretched spring releases energy and can also assist the moving piston 5053 in resetting, driving the hydraulic oil to flow back, thereby quickly causing the central support mechanism 504 to contract.
