Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically to a turning device for metal cutting of the annular end face of a wind turbine base. Background Technology

[0002] The wind turbine base (often referred to as the main frame) is a large metal structural component located at the top of the tower. It serves as the skeleton for all the core equipment within the nacelle. The overall structure is a disc frame with annular flange end faces, and a ring-shaped connecting end face at the bottom for connecting the yaw bearing and tower flange. The base blank is either a casting or a welded part. After cooling and welding, deformation, unevenness, dimensional allowances, and oxide scale will occur. The ring-shaped end face is a critical mating surface for sealing and connection; a rough surface would prevent it from serving as a high-precision mating surface. Metal cutting can improve the quality of the base and meet installation and sealing requirements.

[0003] In existing technologies, large vertical lathes are often used to complete the roughing and finishing of the annular end face of wind turbine bases during machining. During the machining process, metal chips generated are prone to accumulate in large quantities and remain on the end face as the workpiece rotates. As the workpiece rotates, these chips come into contact with the cutting tool and rub against it. Although conventional high-pressure coolant can flush the cutting area, the spray range is limited and the spray is directional, making it impossible to remove all the chips from the machining area. This is especially true for long, curled chips, which are difficult to clean. As a result, the retained chips are squeezed and slide against the tool tip or the side of the tool, which aggravates abnormal tool wear and significantly reduces tool life. Furthermore, the chips crushed by the tool can also create scratches on the end face, damaging the flatness and surface roughness of the end face and reducing the machining quality of the wind turbine base end face.

[0004] Therefore, we propose a metal cutting machine tool device for the annular end face of a wind turbine base to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a turning device for the metal cutting of the annular end face of a wind turbine base, in order to solve the problems mentioned in the background art, such as the large amount of metal waste generated during the turning of the annular end face of the wind turbine base accumulating and remaining on the end face, and being squeezed and slidingly rubbed against the tool tip or side of the tool as the workpiece rotates, which aggravates tool wear, reduces tool life, and also produces scratches on the end face, reducing the machining quality of the end face of the wind turbine base.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. When this invention is used, during the rotation of the rotary table driving the base in the machine tool body, the inclined plate acts as a front baffle, directly intercepting large waste chips that come with the base rotation. The large waste chips are then guided into the chip scraper frame by the rotational thrust of the base, avoiding direct squeezing and friction between the large waste chips and the cutting edge or side of the tool, thus reducing the risk of large-area damage to the tool. At the same time, the first flexible component wipes the end face, intercepting small waste chips and reducing the risk of cutting edge damage and end face scratches. With the cooperation of the chip scraper assembly and the first flexible component, the tool is protected by intercepting waste chips in the forward direction of the tool, reducing the risk of tool wear and end face scratches, and improving the tool life and end face turning quality.

[0023] 2. When using this invention, the elastic element continuously pre-presses the first flexible element downwards to ensure good contact with the end face, preventing debris from leaking out from the bottom gap and being squeezed and rubbed against the tool; the second flexible element wipes the end face a second time to improve the interception rate of fine debris; the scraper assembly extends from the center of the base to the outside of the edge, protecting the tool while gathering the debris on the end face together, making it convenient to clean the debris on the end face after cutting and saving cleaning time.

[0024] 3. When this invention is used, the electromagnetic pulse valve triggers an instantaneous high-pressure pulse water flow every few seconds. The top of the waste in the scraper frame is impacted by the water curtain, and the bottom is impacted by the water flow force, forcing it to move towards the scraper frame outlet and be discharged. This leaves space for subsequent scraping, reduces the pressure on the inclined plate, and ensures that the scraper assembly can work continuously. By intercepting and discharging waste at the same time, the amount of waste on the end face can be reduced, and the workload of subsequent manual cleaning of waste can be reduced.

[0025] 4. When the present invention is used, when the waste enters the scraper frame, the squeezing bar with a small rotation compresses the fluffy waste, reducing the overall volume of the waste and reducing the difficulty of subsequent waste removal. Attached Figure Description

[0039] 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.

[0040] Please see Figures 1-11 As shown, the present invention provides a technical solution:

[0041] A metal cutting machine tool for the annular end face of a wind turbine base includes a cutting machine body 1 and a turning mechanism 2, and further includes:

[0042] Protective mechanism 4 is located on the front surface of the turning tool and is used to intercept metal chips on the forward path of the turning tool.

[0043] The protective mechanism 4 includes a scraper assembly 41 for scraping off large pieces of waste. A first flexible assembly 42 for cleaning fine waste is provided on the front surface of the bottom of the scraper assembly 41. A second flexible assembly 43 for secondary cleaning of fine waste is provided on the rear surface of the bottom of the scraper assembly 41. A cleaning assembly 44 for discharging waste is provided inside the scraper assembly 41.

[0044] The chip scraper assembly 41 includes a chip scraper frame 411, and an inclined plate 412 for scraping large waste chips is fixedly installed on the front surface of the chip scraper frame 411.

[0045] The first flexible component 42 includes an installation strip 421, with an elastic element 422 fixedly connected to the bottom of the installation strip 421, and a first flexible element 423 flexibly attached to the bottom of the elastic element 422 and flexibly conforming to the annular end face of the base.

[0046] In practical applications, the cutting machine body 1 mainly consists of a rotary table, a clamping mechanism, two side columns, a top crossbeam, and a movable crossbeam. The turning mechanism 2 is mounted on the movable crossbeam. The turning mechanism 2 includes a slide tool holder that can move horizontally and vertically, as well as a turning tool. The protective mechanism 4 is mounted on the forward path of the turning mechanism 2 through a limiting mechanism 3. The limiting mechanism 3 laterally limits the protective mechanism 4. The movement of the turning mechanism 2 can drive the protective mechanism 4 to move up and down together. When the wind turbine base is placed on the rotary table and positioned by the clamping mechanism, the movable crossbeam drives the turning mechanism 2 to move downward, so that the cutting tool contacts the end face of the base. At the same time, the turning mechanism 2 drives the protective mechanism 4 to move downward together, so that the first flexible component 42 and the second flexible component 43 flexibly fit against the end face of the base. That is, when the scraper frame 411 moves downward, the first flexible component 423 first contacts the end face of the base, and as the scraper frame 411 continues to move, it squeezes the first flexible component 423, making it tightly fit against the end face of the base. At the same time, the elastic component 422 is compressed and contracted. At this time, the bottom of the sharp corner of the inclined plate 412 is close to the end face of the base. Driven by the rotary table, the base rotates counterclockwise. Metal shavings on the end face first arrive at the scraper assembly 41. The inclined plate 412 acts as a front baffle, directly intercepting large, curled, and long shavings that come with the base's rotation. The workpiece's rotational force guides the large shavings into the scraper frame 411, preventing them from directly rubbing against the cutting edge or side of the tool, thus reducing the risk of large-area tool damage. Simultaneously, the first flexible component 423 wipes the end face, intercepting fine shavings and preventing them from rubbing against the cutting edge, reducing the risk of blade damage and end face scratches, improving tool life and end face quality. With the base's rotation, more fine shavings are intercepted and accumulate on the inclined plate 412. At the sharp corner of 12, when a large amount of small waste chips accumulate, they will also be guided into the scraper frame 411 under the rotational force of the base, improving the interception effect of waste chips on the forward path. With the cooperation of the scraper assembly 41 and the first flexible assembly 42, the tool is protected by intercepting waste chips in the forward direction of the tool, reducing the risk of tool wear and end face scratches, thereby improving the turning quality of the base end face. This solves the problem that a large amount of metal waste chips generated during the turning of the annular end face of the wind turbine base will accumulate and remain on the end face, and will be squeezed and rubbed against the tool tip or tool side as the workpiece rotates, aggravating tool wear, reducing tool life, and also causing scratches on the end face, reducing the machining quality of the wind turbine base end face.

[0047] The first flexible component 423 can be made of high wear-resistant polyurethane material, which has moderate softness and hardness and can fit the uneven end face to better intercept small chips. It is also resistant to cutting oil and coolant immersion, and is not easy to tear when scraping metal chips, with a long wear life. The elastic component 422 can be made of polyurethane elastic pad, which has a certain elasticity and can continuously pre-press the first flexible component 423 downward to keep it in good fit with the end face. It compensates for the small gaps caused by long-term wear of the first flexible component 423, prevents chips from leaking from the bottom gap and squeezing and rubbing against the tool, and improves the interception effect of fine chips.

[0048] It should also be noted that the second flexible component 43 includes an arc-shaped strip 431, and the bottom of the arc-shaped strip 431 is fixedly connected to a second flexible element 432.

[0049] See Figure 5 and Figures 8 to 9 As shown, the second flexible member 432 is located behind the first flexible member 423 and is installed on the bottom rear side of the scraper frame 411. It moves downward with the scraper frame 411 and presses down and adheres to the end face together with the first flexible member 423. When the base rotates, the first flexible member 423 acts as the first interception barrier for fine waste, while the second flexible member 432 acts as the second interception barrier, wiping the remaining fine waste a second time and improving the fine waste interception rate.

[0050] The chip removal component 44, the second flexible component 43, and the first flexible component 42 are all matched with the length of the chip scraper component 41. The chip scraper component 41 is relatively long, extending from the center of the base to the outer edge. While protecting the cutting tool, it can gather the waste chips generated by end face turning together, making it convenient to clean the end face waste chips after cutting and saving cleaning time.

[0051] It should also be noted that the chip removal assembly 44 includes a pulse tube 441, with a water inlet pipe 442 fixedly connected to the top of the pulse tube 441. An electromagnetic pulse valve 443 is provided on the outer surface of the water inlet pipe 442. Multiple connecting pipes 444 are fixedly connected to the bottom of the pulse tube 441, and a linear nozzle 445 is fixedly connected to the bottom end of each connecting pipe 444. A water outlet pipe 446 is fixedly connected to the edge of the bottom of the pulse tube 441. An arc-shaped groove 413 is formed on the bottom surface inside the chip scraper frame 411. Multiple diverter plates 414 are fixedly connected to the inner wall of the arc-shaped groove 413, and a baffle strip 415 is fixedly connected to the edge of the arc-shaped groove 413. A water tank 418 is formed inside the chip scraper frame 411. Multiple water outlet holes 419 are formed on the bottom surface of the inner wall of one side of the water tank 418. The bottom ends of the water outlet pipes 446 are all fixedly connected through the chip scraper frame 411 to the interior of the water tank 418. The bottom end of each connecting tube 444 is fixedly inserted into the interior of the scraper frame 411, the bottom of the pulse tube 441 is fixedly installed on the top of the scraper frame 411, and the top of each linear nozzle 445 is fixedly installed on the top surface inside the scraper frame 411.

[0052] See Figures 5 to 8 As shown, one end of the water inlet pipe 442 is connected to the machine tool's coolant system via an external pipe. An arc-shaped groove 413 is formed on the bottom surface inside the chip scraper frame 411, concentrating the water flow to form a channel for subsequent flushing and chip removal. Under the action of multiple diverter plates 414, the arc-shaped groove 413 divides the bottom water flow into multiple independent high-speed water jets. The arc-shaped groove 413 is inclined, slightly higher near the water outlet 419 and slightly lower near the outlet. This inclined direction, combined with the multiple water jets, facilitates better movement and discharge of small waste chips. A baffle bar 415 is located at the edge of the arc-shaped groove 413. It prevents accidental leakage of coolant from the edge water channel, reverses some of the waste chips on the inclined plate 412 back to the end face, and also blocks waste chips in the chip scraper frame 411, preventing them from accidentally sliding out of the frame during chip removal and reducing the impact on the chip scraping assembly 41.

[0053] Coolant enters the pulse pipe 441 through the inlet pipe 442. Then, part of the coolant enters the linear nozzle 445 through the connecting pipe 444, and part enters the water tank 418 through the outlet pipe 446. At this time, each independent water jet exits through its corresponding outlet hole 419, forming an impact water flow at the bottom. Simultaneously, multiple linear nozzles 445 at the top spray a water curtain obliquely towards the outlet direction. Small-volume debris in the scraper frame 411 is impacted by the water curtain at the top and by the force of the impact water flow at the bottom, forcing it to move towards the outlet of the scraper frame 411, thereby discharging the small debris inside the scraper frame 411. In addition, the coolant can cause large pieces of waste chips cut off to spiral and quickly wrap around each other, reducing the volume of waste chips and thus reducing the difficulty of flushing and removing them. By expanding the chip storage space, more waste chips are prevented from accumulating in the frame, which would cause subsequent waste chips to accumulate on the inclined plate 412, reducing the pressure on the inclined plate 412 and ensuring that the chip scraping assembly 41 can work continuously, thus improving the chip interception effect. Furthermore, with the cooperation of the chip cleaning assembly 44, the protective mechanism 4 intercepts waste chips while discharging them from the end face, reducing the amount of waste chips on the end face, reducing the workload of manually cleaning the end face waste chips after shutdown, and improving convenience.

[0054] An electromagnetic pulse valve 443 is installed on the outer surface of the water inlet pipe 442. It triggers an instantaneous high-pressure pulse water flow every few seconds. It does not pursue continuous water spraying, reduces coolant waste, provides sufficient impetus for subsequent chip removal, reduces the risk of fine particles settling in dead corners at the bottom of the tank and large waste chips stagnating due to insufficient moving power, and improves chip removal stability.

[0055] It should also be noted that the scraper frame 411 is equipped with multiple sets of extrusion components 5 for extruding the loose waste entering the scraper frame 411. Each extrusion component 5 includes a sleeve rod 501. Multiple extrusion strips 502 are fixedly installed on the outer surface of the sleeve rod 501. A fixing rod 503 is movably embedded inside the sleeve rod 501. The two ends of the fixing rod 503 are fixedly installed at the edge inside the scraper frame 411. A fan-shaped strip 504 is fixedly installed on the outer surface of the fixing rod 503. A fan-shaped groove 505 is opened on the inner wall of the sleeve rod 501. The outer surface of the fan-shaped strip 504 is movably embedded inside the fan-shaped groove 505.

[0056] See Figure 5 and Figures 10 to 11 As shown, the extrusion assembly 5 is located at the feed inlet of the scraper frame 411. The waste chips introduced by the inclined plate 412 first pass through the extrusion strips 502. Multiple extrusion strips 502 divide the feed channel into multiple small feed areas. When the waste chips enter the scraper frame 411, two adjacent extrusion strips 502 can compress the fluffy waste chips, reduce the overall volume of the waste chips, and thus reduce the difficulty of subsequent chip removal.

[0057] The sleeve rod 501 is movably connected to the fixed rod 503, and with the cooperation of the sector bar 504 and the sector groove 505, the sleeve rod 501 can rotate back and forth slightly on the outer surface of the fixed rod 503, so that the extrusion bar 502 can be in a movable state that can rotate slightly. When the waste is guided over, the extrusion bar 502 can rotate slightly to assist in extrusion and improve the waste compression effect.

[0058] It should also be noted that a locking component 6 is fixedly installed at the bottom edge of the scraper frame 411, which is used to lock the first flexible component 42 and the second flexible component 43. The locking component 6 includes a fixing block 601 and two locking rods 602. The top of the fixing block 601 is fixedly installed at the bottom edge of the scraper frame 411. A spring 603 is movably embedded inside the fixing block 601. One end of the two locking rods 602 is fixedly connected to the outer surfaces of the two sides of the spring 603, and the other end of the two locking rods 602 movably extends through the outer surface of the fixing block 601. Two T-shaped grooves 416 are provided at the bottom of the inclined plate 412. Two T-shaped bars 424 are fixedly installed at the top of the mounting strip 421. The outer surfaces of the two T-shaped bars 424 are movably embedded in the two T-shaped grooves 416. A first locking groove 425 is provided on the rear surface of the mounting strip 421. A spherical strip 433 is fixedly installed at the bottom of the arc strip 431. A spherical groove 417 is provided on the rear surface of the bottom of the scraper frame 411. The outer surface of the spherical strip 433 is movably embedded in the spherical groove 417. A second locking groove 434 is provided on the front surface of the arc strip 431. The other ends of the two locking rods 602 are movably embedded in the first locking groove 425 and the second locking groove 434, respectively.

[0059] See Figures 5 to 6 and Figures 8 to 9 As shown, after the first flexible component 42 and the second flexible component 43 slide below the scraper component 41, they are fixed by the locking component 6, improving the stability of the first flexible component 42 and the second flexible component 43. The spring component 603 consists of a spring and two side plates, as shown... Figure 9 As shown, the bottom of the fixing block 601 has a sliding hole that matches the bottom of the side plate, and the locking rod 602 is installed on the outer surface of the side plate. Squeezing the two side plates causes the two locking rods 602 to move relative to each other, disengaging from the corresponding first locking groove 425 and second locking groove 434. Then, the first flexible component 423 and the second flexible component 432 are pulled outward, so that the T-shaped strip 424 is pulled out from the T-shaped groove 416 and the spherical strip 433 is pulled out from the spherical groove 417. The first flexible component 42 and the second flexible component 43 can then be replaced, making replacement convenient and flexible, and improving convenience.

[0060] It should also be noted that the rear surface of the protective mechanism 4 is provided with a limiting mechanism 3. The limiting mechanism 3 includes a mounting frame 301, a mounting plate 303, and a fixing frame 305. Two slide rails 302 are fixedly mounted on the front surface of the mounting frame 301. Slide plates 307 are movably fitted on the outer surfaces of the two slide rails 302. The front surfaces of the two slide plates 307 are respectively installed on the two side edges of the rear surface of the chip scraper frame 411. The mounting frame 301 is installed on the inner wall of the cutting machine tool body 1. The mounting plate 303 is bolted to the front surface of the turning mechanism 2. Two support rods 304 are fixedly mounted at the bottom of the front surface of the mounting plate 303. The bottom of the fixing frame 305 is fixedly installed on the top of the chip scraper frame 411. A groove 306 is opened inside the fixing frame 305. The outer surfaces of the two support rods 304 are movably embedded in the groove 306.

[0061] See Figures 3 to 4 As shown, the sliding plate 307 cooperates with the slide rail 302 to laterally position the protective mechanism 4, allowing it to move only up and down. When the turning mechanism 2 moves up and down, it drives the mounting plate 303 to move together, which in turn drives the support rod 304 to move together. With the cooperation of the sliding plate 307 and the slide rail 302, the support rod 304 slides inside the slide groove 306 while moving up and down, and generates an upward or downward force on the fixing frame 305, thereby driving the protective mechanism 4 to move up and down. Under the action of the limiting mechanism 3, the movement of the protective mechanism 4 is realized by the up and down movement of the turning mechanism 2, reducing interference with the loading and unloading of the wind turbine base and facilitating subsequent maintenance and cleaning of the protective mechanism 4.

[0062] Please see Figures 1-11As shown, the overall effect and working principle of the mechanism are as follows: When the turning mechanism 2 moves down, it drives the mounting plate 303 and the support rod 304 to move together. With the cooperation of the slide plate 307 and the slide rail 302, the support rod 304 pushes the fixed frame 305 down, thereby driving the protective mechanism 4 down. This causes the first flexible member 423 and the second flexible member 432 to first flexibly fit against the end face of the base. Then, the bottom of the sharp corner of the inclined plate 412 moves to the end face of the base. When the rotary table in the machine tool body 1 drives the base to rotate, the inclined plate 412 directly intercepts large waste chips and uses the workpiece rotation thrust to guide the waste chips into the scraper frame 411. The first flexible member 423 wipes the end face and intercepts small waste chips. Then, the second flexible member 432 wipes the remaining small waste chips a second time. Under the action of the electromagnetic pulse valve 443, an instantaneous high-pressure pulse water flow is triggered every few seconds. The coolant enters the linear nozzle 445 and the water tank 418 through the inlet pipe 442 and the pulse pipe 441 respectively, and then exits through the outlet hole 419. An impact water flow is formed at the bottom, while multiple linear nozzles 445 at the top spray water curtain at an angle. The top of the waste is impacted by the water curtain, and the bottom is impacted by the flow force of the impact water flow, forcing it to move towards the outlet of the scraper frame 411, thereby discharging the waste inside the scraper frame 411.

[0063] Among them, the cutting machine tool body 1, the turning mechanism 2 and the electromagnetic pulse valve 443 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
