Description

Technical Field

[0001] This invention relates to the technical field of wind power, and in particular to an integrated machining device for milling and drilling wind turbine spindles. Background Technology

[0002] In the manufacturing process of wind power equipment, as the power generation capacity of wind turbines increases, the length and diameter of wind turbine main shafts also increase. Traditional machining methods for wind turbine main shafts involve using horizontal lathes, vertical lathes, and milling and boring machines, requiring 3-4 machine tools to complete the process. This results in very high equipment costs, repeated clamping and adjustment, and low processing efficiency. As the workpiece becomes larger, the equipment also gradually increases in size, leading to higher costs with little improvement in efficiency.

[0003] The traditional working principle of wind turbine spindle machining mainly involves lathe turning, where the lathe's main motor provides torque to overcome cutting resistance. The larger the workpiece diameter, the greater the machining resistance, requiring a larger, more powerful, and energy-intensive motor to overcome this resistance. Rough machining involves large cutting depths and slow feed rates, resulting in low efficiency; finish machining requires high speeds and high energy consumption. Therefore, an integrated machining device for milling and drilling wind turbine spindles is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated machining device for milling and drilling wind turbine spindles, in order to solve the defects of existing lathe turning methods for machining wind turbine spindles, which have very high equipment costs and low processing efficiency.

[0007] Preferably, a clamping tailstock is installed at the top of one side of the base, a first moving mechanism is installed on one side of the top of the clamping tailstock, a first motor is installed at the top of the first moving mechanism, a first reducer is installed at one end of the first motor, a support frame is installed on one side of the first reducer, a connecting shaft is installed inside the support frame, a drill bit is installed at one end of the connecting shaft, and one end of the first reducer is connected to one end of the connecting shaft via a belt.

[0008] Preferably, the slide rails are provided in two sets, and the two sets of slide rails are symmetrically distributed on both sides of one end of the base.

[0009] Preferably, the slide rail is provided with an anti-fall structure, which includes a mounting plate installed at the middle position inside the slide rail. A sealing cylinder is installed at the top of the mounting plate, a piston is installed inside the sealing cylinder, a fixing block is fixed at the top of the piston, a cylinder is installed at the top of the fixing block, connecting blocks are installed on both sides of the fixing block, a mounting block is installed at the top of the connecting block, and a disc is movably installed inside the mounting block.

[0010] Preferably, the two ends of the cylinder are connected to the two sides inside the fixed block, and the cylinder and the fixed block form a movable connection.

[0011] Preferably, guide rods are installed on both sides of the bottom end of the fixing block, springs are installed on the outer side of the guide rods, and the bottom end of the guide rods penetrates the interior of the mounting plate.

[0012] Preferably, a threaded sleeve is installed at the bottom end of the mounting base and the slide, and an extrusion plate is installed on both sides of the threaded sleeve.

[0013] Preferably, the two ends of the spring are fixed to the bottom end of the fixing block and the top end of the mounting plate, and the spring and the fixing block form a telescopic structure.

[0014] Preferably, the guide rods are provided in two sets, and the two sets of guide rods form a guide connection with the mounting plate.

[0015] The present invention provides an integrated machining device for milling and drilling wind turbine spindles, the advantages of which are:

[0016] By incorporating auxiliary structures, during the machining of wind turbine main shafts, the cooperation between the cutter head and the boring bar allows the cutter head to be used only for roughing, while the boring bar can perform both roughing and finishing. A multi-bladed, small-cutting-amount, high-speed feed method decomposes the workpiece machining into a series of grooves, which are then machined by the rotating multi-bladed cutter head. Roughing can be performed simultaneously on both sides, while finishing is done solely by the boring bar. This significantly improves roughing efficiency and reduces equipment energy consumption.

[0017] Furthermore, a milling-to-turn machining method is adopted, which also has milling-turning-drilling composite functions. It employs a multi-bladed, small-feed-rate, high-speed cutting strategy, but with a large amount of metal removed per unit time, significantly improving cutting efficiency. The machine tool also has milling-turning-drilling composite machining capabilities, allowing multiple machining operations to be completed in a single setup, reducing downtime and increasing production efficiency by over 90%. This results in even higher efficiency when machining wind turbine spindles.

[0018] By incorporating an anti-fall structure, the lead screw in the position movement assembly is prevented from sagging at its middle position during use. Therefore, a fixed block is used to support the lead screw. Furthermore, two sets of cylinders are movably connected inside the fixed block, ensuring that the cylinders do not affect the movement of the lead screw while supporting it.

[0019] Furthermore, by using the pressing plate and the disc in combination, the fixing block can be pressed down when the thread sleeve passes the position of the fixing block, so that the fixing block will not affect the movement of the thread sleeve when supporting it. And by using two sets of springs, the fixing block can return to its original position and continue to support when the downward pressing force on the fixing block disappears, thus completing the support work for the lead screw and preventing the lead screw from sagging at its middle position during use, which would affect the accuracy.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-13 The present invention provides an integrated processing device for milling and drilling wind turbine main shafts, comprising a base 1 and a mounting box 2; the mounting box 2 is mounted on the top of the base 1, a faceplate 4 is mounted on one end of the mounting box 2, a first reduction motor 3 is mounted on one side of the other end of the faceplate 4, and slide rails 7 are mounted on both sides of one end of the base 1; an auxiliary structure 5 is provided on the top of the slide rail 7.

[0036] The auxiliary structure 5 includes a slide 5021, which is mounted on the top of a side-position moving component 6. A rotary disk 5019 is movably mounted on the top of the slide 5021. A connecting seat 5020 is mounted on the top of the rotary disk 5019. A mounting platform 503 is set on the top of the connecting platform 5020. A cutting component 501 is mounted on the top of the mounting platform 503. A boring bar 5018 is set on one side of the cutting component 501. A feed servo motor 502 is set on one side of the boring bar 5018. A mounting base 509 is mounted on the top of the side-position moving component 6 at one end of the mounting box 2. A connecting frame 5015 is mounted on the top of the mounting base 509. A second moving mechanism 5010 is mounted on one side of the top of the connecting frame 5015. A second motor 5013 is mounted on the top of the second moving mechanism 5010. A second reducer 5012 is installed at one end of the base 1. A gearbox 5014 is installed at one end of the second reducer 5012. A cutter head 5011 is installed at the top of the gearbox 5014. A clamping tailstock 508 is installed at the top of one side of the base 1. A first moving mechanism 507 is installed on one side of the top of the clamping tailstock 508. A first motor 506 is installed at the top of the first moving mechanism 507. A first reducer 505 is installed at one end of the first motor 506. A support frame 504 is installed on one side of the first reducer 505. A connecting shaft 5016 is installed inside the support frame 504. A drill bit 5017 is installed at one end of the connecting shaft 5016. One end of the first reducer 505 is connected to one end of the connecting shaft 5016 via a belt. Two sets of slide rails 7 are provided, and the two sets of slide rails 7 are symmetrically distributed on both sides of one end of the base 1.

[0037] Reference Figures 1-8As shown: During the processing of the wind turbine main shaft, the wind turbine main shaft is first installed on one side of the faceplate 4. After the wind turbine main shaft is installed, the moving component at the bottom of the clamping tailstock 508 is activated to adjust the position of the clamping tailstock 508 so that one side of the top of the clamping tailstock 508 abuts against one side of the wind turbine main shaft, thus clamping the wind turbine main shaft. After the wind turbine main shaft is installed, the drive motor is installed at one end of the first reduction motor 3 to provide power. Then, the drive motor is activated to drive the gear at one end of the first reduction motor 3 to rotate, thereby driving the faceplate 4 to rotate through meshing with the gear ring at one end of the faceplate 4, indirectly driving the wind turbine main shaft to rotate. After the wind turbine main shaft is installed, the mounting base 509 can be positioned by using the position moving component 6. The movable component 6 is moved to the outside to adjust the position of the mounting base 509, allowing it to process the wind turbine main shaft at different positions. When processing the wind turbine main shaft is required, the second motor 5013 is started. After starting, the second motor 5013, in cooperation with the second reducer 5012, drives the gear inside the gearbox 5014 to rotate. When the gear rotates, it drives the cutter head 5011 to rotate. When the cutter head 5011 rotates, the second moving mechanism 5010 is activated to adjust the position of the cutter head 5011, allowing it to perform rough machining on the outside of the wind turbine main shaft. Furthermore, while the cutter head 5011 is machining the wind turbine main shaft, the boring bar 5018 can also be activated to machine the wind turbine main shaft, and the machining can be performed by... The position of the boring bar 5018 is adjusted by the servo motor 502. A cutter head 5011 and a boring bar 5018 are arranged on each side of the wind turbine spindle. The cutter head 5011 is used only for roughing, while the boring bar 5018 can perform both roughing and finishing. A multi-bladed, small-cutting-amount, high-speed feed method decomposes the workpiece machining into grooves. The multi-bladed cutter head 5011 rotates for machining. During roughing, both sides can be machined simultaneously, while during finishing, the boring bar 5018 alone performs the machining. This significantly improves roughing efficiency and reduces equipment energy consumption. Furthermore, while the boring bar 5018 is machining, the rotating disk 5019 can be rotated by a motor at its bottom, allowing for angle machining during the boring bar 5018's operation. The degree of adjustment is used to process the arc of the wind turbine main shaft. When drilling is required on the wind turbine main shaft, the first motor 506 is started. After starting, the first motor 506 drives the connecting shaft 5016 to rotate through the first reducer 505, thereby driving the drill bit 5017 to rotate. Then, the first moving mechanism 507 is started to move the drill bit 5017 to process the wind turbine main shaft. With the above structure, multiple processing steps can be achieved simultaneously when processing the wind turbine main shaft. This device replaces the traditional lathe and drilling machine for processing the wind turbine main shaft. It has high processing efficiency while significantly reducing costs and energy consumption. The integrated turning, milling and drilling composite completes the entire process of wind turbine main shaft processing in one clamping, saving clamping time and greatly improving processing efficiency.

[0038] The slide rail 7 is internally equipped with an anti-fall structure 8, which includes a mounting plate 801. The mounting plate 801 is installed in the middle position inside the slide rail 7. A sealing cylinder 809 is installed at the top of the mounting plate 801. A piston 8010 is installed inside the sealing cylinder 809. A fixing block 806 is fixed at the top of the piston 8010. A cylinder 805 is installed at the top of the fixing block 806. Connecting blocks 802 are installed on both sides of the fixing block 806. A mounting block 803 is installed at the top of the connecting block 802. A disc 804 is movably installed inside the mounting block 803. The two ends of the cylinder 805 are connected to the two sides inside the fixing block 806. A movable connection is formed between the fixed block 806 and the mounting plate 801. Guide rods 807 are installed on both sides of the bottom end of the fixed block 806. Springs 808 are installed on the outer side of the guide rods 807. The bottom end of the guide rods 807 penetrates the interior of the mounting plate 801. Threaded sleeves 8011 are installed at the bottom ends of the mounting base 509 and the slide 5021. Extrusion plates 8012 are installed on both sides of the threaded sleeves 8011. The two ends of the springs 808 are fixed to the bottom end of the fixed block 806 and the top end of the mounting plate 801. The springs 808 and the fixed block 806 form a telescopic structure. Two sets of guide rods 807 are provided. The two sets of guide rods 807 form a guiding connection with the mounting plate 801.

[0039] Reference Figures 9-13 As shown: After the position moving component 6 is installed, the fixing block 806 is installed at the bottom end of the lead screw of the position moving component 6. After installation, the cylinder 805 can support the middle position of the lead screw to prevent it from sagging and affecting the transmission accuracy. When the lead screw is working, since the two ends of the cylinder 805 and the fixing block 806 are movably connected, they support the lead screw without affecting its rotation. When the lead screw drives the sleeve 8011 to the position of the cylinder 805, the pressing plate 8012 is used. Through the setting of the bevels on both sides, the pressing disc 804 moves downward. When the disc 804 moves downward, it indirectly presses the fixing block 806 downward. This allows the cylinder 805 at the top of the fixed block 806 to avoid the threaded sleeve 8011, thus not affecting the use of the threaded sleeve 8011. When the fixed block 806 moves downward, it first drives the piston 8010 to compress the air inside the sealing cylinder 809. When the fixed block 806 moves downward, it pushes the guide rod 807 downward, thereby compressing the spring 808. After the threaded sleeve 8011 passes the top of the cylinder 805, under the action of the spring 808, the fixed block 806 returns to its original position and continues to support the lead screw of the position moving component 6. This prevents the lead screw from sagging at its middle position during use, thus affecting the transmission accuracy and completing the support work.
