Description

Technical Field

[0001] This invention relates to the field of wind power equipment processing technology, specifically to a beveling device and processing method for wind power steel plate components. Background Technology

[0002] The core components of wind power equipment, such as towers and frames, are mostly made of thick steel plates spliced ​​and welded together. The processing accuracy of the welding bevel directly determines the welding quality and the structural strength of the equipment. Therefore, there are strict requirements for the consistency of the bevel angle, straightness and processing efficiency.

[0003] A cutting machine and its processing method for beveling steel plates, with patent publication number CN113681333A, are disclosed. In actual use, the beveling device for wind power steel plates proposed in this patent requires manual assistance to move the steel plate feeding and milling components, making it impossible to achieve automatic feeding and processing of steel plates. Furthermore, the steel plates are prone to shifting and deviating due to milling force during milling, resulting in beveling deviations. At the same time, the iron filings and waste generated during processing tend to accumulate in the milling area, requiring manual shutdown for cleaning. This not only affects the beveling accuracy but also interrupts the processing flow, further reducing work efficiency.

[0019] S2. Place the wind turbine steel plate on the conveying roller and guide roller 303 of the extension frame 301, start the feeding motor 308 and drive motor 501 to realize the automatic horizontal feeding of the steel plate at the same time, and drive the wind guide impeller 403 to rotate to purge the processing area in advance.

The airflow is precisely sprayed from the air nozzle to the processing area at the waste collection port through the air guide pipe and the split air pipe. One power input simultaneously completes the conveying and feeding of the steel plate and the blowing and collection of processing waste, realizing the feeding and waste removal operations. It effectively avoids the accumulation of processing waste in the milling area, which affects the beveling accuracy. At the same time, it cooperates with the collection shell to complete the centralized collection of waste, which greatly improves the overall efficiency of wind power steel plate beveling and the cleanliness of the working environment.

[0024] (2) The beveling device and processing method for wind power steel plates achieve automation and high efficiency in the beveling process by integrating the mechanical linkage design of the transmission components and coordinating the beveling, automatic feeding and waste cleaning components.

[0040] 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.

[0041] Please see Figures 1-9 The present invention provides a technical solution: a beveling device for wind power steel plate components, including a workbench 1, on the surface of which beveling components 2, automatic feeding components 3, waste cleaning components 4 and transmission components 5 are provided.

[0042] The transmission assembly 5 includes fixed plates fixedly connected to both sides of the operating frame 201. A drive motor 501 is fixedly connected to the surface of the fixed plates. A drive shaft 502 is fixedly connected to the output end of the drive motor 501. One end of the drive shaft 502 away from the drive motor 501 extends into the interior of the waste collection port 401 and is fixedly connected to one end of the second conveying roller 304. A drive synchronous pulley 503 is fixedly connected to the surface of the drive shaft 502. A driven shaft 504 is rotatably connected to the back of the worktable 1.

A synchronous belt 509 is installed between the drive synchronous pulley 503 and the driven synchronous pulley 505.

[0043] A linkage shaft 507 is rotatably connected to the back of the workbench 1. A second transmission gear 508 is fixedly connected to the surface of the linkage shaft 507. A first transmission gear 506 meshes with the second transmission gear 508, and the diameter of the first transmission gear 506 is four times that of the second transmission gear 508. The waste cleaning assembly 4 includes an air duct 402 fixed to the surface of the fixed plate. The end of the linkage shaft 507 away from the workbench 1 extends into the interior of the air duct 402, and an air guide impeller 403 is fixed to the end of the linkage shaft 507. Several air inlets 404 are opened on the front of the air duct 402, and an air guide pipe 405 is fixedly embedded on the back of the air duct 402.

[0044] Through the transmission of the synchronous belt 509, the power of the drive shaft 502 can be transmitted to the driven shaft 504, realizing the synchronous rotation of the driven shaft 504. A linkage shaft 507 is rotatably connected to the back of the worktable 1 corresponding to the position of the first transmission gear 506. The linkage shaft 507 is vertically arranged, and its bottom end is connected to the back of the worktable 1 through a bearing. A second transmission gear 508 is fixedly connected to the surface of the linkage shaft 507. The first transmission gear 506 and the second transmission gear 508 mesh with each other, and the diameter of the first transmission gear 506 is four times that of the second transmission gear 508. Through the gear reduction and torque increase transmission, the linkage shaft 507 can be driven to rotate at high speed, providing power for the waste cleaning component 4.

[0045] A horizontal plate is fixedly connected to the inner wall of the mounting frame 204. A diversion air pipe 406 is fixedly connected to the lower surface of the horizontal plate. Several jet nozzles 407 are fixedly embedded on the lower surface of the diversion air pipe 406. The jet nozzles 407 are evenly distributed in a straight array on the lower surface of the diversion air pipe 406. Both ends of the diversion air pipe 406 are fixedly connected to air inlet hoses 408. The end of the air inlet hose 408 away from the diversion air pipe 406 is fixedly connected to the end of the air guide pipe 405 away from the air guide tube 402. The position of the diversion air pipe 406 corresponds to the waste collection port 401, and the jet nozzles 407 are located directly above the waste collection port 401. A collection shell 409 corresponding to the position of the waste collection port 401 is fixed on the lower surface of the workbench 1.

[0046] The jet nozzle 407 is located directly above the waste collection port 401, ensuring that the airflow can be accurately directed towards the milling area. Both ends of the split air pipe 406 are fixedly connected to air inlet hoses 408. The air inlet hoses 408 are flexible rubber tubes, with one end away from the split air pipe 406 fixedly connected to the other end of the air guide pipe 405 away from the air guide tube 402, achieving stable airflow delivery. The air inlet hoses 408 can extend and retract with the lifting and lowering of the mounting frame 204, without affecting the height adjustment of the beveling assembly 2. The lower surface of the worktable 1 is fixed with a collection shell 409 corresponding to the position of the waste collection port 401 via a bracket. The collection shell 409 is a rectangular shell with an opening at the top, its opening communicating with the bottom end of the waste collection port 401, used to collect the processing waste after blowing, achieving centralized waste collection.

[0047] The beveling assembly 2 includes an operating frame 201 fixed to the back of the worktable 1. A lifting screw 202 is rotatably arranged on the inner side of the operating frame 201. A lifting block 203 is threadedly connected to the surface of the lifting screw 202. A mounting frame 204 is fixedly connected to the front end of the lifting block 203. An adjustment assembly 6 is rotatably arranged on the inner side of the mounting frame 204. A milling cutter 205 is rotatably arranged on the surface of the adjustment assembly 6.

[0048] While driving the second conveying roller 304 to feed the steel plate, the drive motor 501 simultaneously drives the guide impeller 403 to rotate at high speed. When the guide impeller 403 rotates, it draws in air from outside the guide duct 402 through the air inlet 404, forming a high-speed airflow inside the guide duct 402. The airflow enters the split air pipe 406 through the guide pipe 405 and the air inlet hose 408, and then is precisely sprayed onto the milling area at the waste collection port 401 through several jet nozzles 407. The iron filings and waste generated during milling are directly blown into the waste collection port 401 and finally fall into the collection shell 409 for centralized collection. A single power input simultaneously completes the feeding of the steel plate and the blowing and collection of processing waste, eliminating the need for an additional power mechanism for waste cleaning, reducing the manufacturing cost and operating energy consumption of the equipment. At the same time, it achieves the synchronization of feeding and waste cleaning actions, effectively preventing the accumulation of processing waste in the milling area from affecting the normal operation of the milling cutter 205 and the beveling accuracy, and ensuring the flatness of the beveling surface.

[0049] A lifting motor 206 is fixedly connected to the inner side of the operating frame 201. The rotating shaft of the lifting motor 206 is fixedly connected to the top end of the lifting screw 202. The surface of the lifting block 203 is provided with a threaded hole that matches the lifting screw 202. The lifting block 203 is threadedly connected to the surface of the lifting screw 202 through the threaded hole. Limit blocks 207 are fixedly connected to both sides of the lifting block 203. Two limit rods are fixedly connected to the inner side of the operating frame 201. The limit blocks 207 are slidably connected to the surfaces of the limit rods.

[0050] The lifting motor 206 provides power for the rotation of the lifting screw 202. The forward and reverse rotation of the lifting motor 206 can drive the lifting screw 202 to rotate, thereby driving the lifting block 203 to move vertically up and down along the limit rod, realizing the adjustment of the beveling height. It is suitable for the beveling requirements of wind power steel plates of different thicknesses. There is no need for manual adjustment of the milling height. The adjustment accuracy is high and the operation is convenient, effectively improving the adaptability of the device.

[0051] The adjustment assembly 6 includes a mounting shell fixedly connected to one side of the mounting frame 204, and two adjustment shafts rotatably connected to the inner side of the mounting frame 204. An adjustment motor 601 is fixedly connected to the upper surface of the mounting shell. A worm gear 602 is fixedly connected to the rotating shaft of the adjustment motor 601. An adjustment seat 603 is fixedly connected to the opposite ends of the two adjustment shafts. A rotary motor 604 is fixedly connected to the inner wall of the adjustment seat 603. The rotating shaft of the rotary motor 604 extends to the outside of the adjustment seat 603 and is fixedly connected to the surface of the milling cutter 205. The position of the milling cutter 205 corresponds to the waste collection port 401. One end of the adjustment shaft extends into the interior of the mounting shell and is fixedly connected to a worm wheel 605. The worm gear 602 meshes with the worm wheel 605.

[0052] By adjusting the motor 601 to drive the worm gear 602 to rotate, the worm wheel 605 and the adjusting shaft can be driven to rotate synchronously, which in turn drives the adjusting seat 603 to rotate around the axis of the adjusting shaft, thereby realizing the adjustment of the machining angle of the milling cutter 205. Different bevel angles can be adjusted according to the welding requirements of wind power steel plate parts. After the adjustment is completed, the angle of the milling cutter 205 remains stable and will not be deviated due to machining vibration, ensuring the consistency of the bevel machining angle and improving the bevel machining accuracy.

[0053] An electric telescopic rod 305 is fixedly connected to the upper surface of the horizontal plate. The telescopic end of the electric telescopic rod 305 extends to the bottom of the horizontal plate and is fixedly connected to a limiting pressure plate 306. Several limiting pressure rollers 307 are rotatably connected to the surface of the limiting pressure plate 306. The limiting pressure rollers 307 are located above the second conveying roller 304. Two guide slide rods are fixedly connected to the upper surface of the limiting pressure plate 306. A sliding through hole matching the guide slide rod is opened on the surface of the horizontal plate. The guide slide rod is slidably connected to the inner wall of the sliding through hole.

[0054] The extension and retraction of the electric telescopic rod 305 can drive the limiting pressure plate 306 to move vertically, causing the limiting pressure roller 307 to press downwards onto the upper surface of the steel plate. This, together with the second conveying roller 304 below, achieves vertical clamping and limiting of the steel plate, preventing the steel plate from shifting or deviating due to milling force during beveling, ensuring the straightness of the steel plate feeding, and thus ensuring the straightness and accuracy of the beveling process. The limiting pressure roller 307 can rotate synchronously with the steel plate conveying, without obstructing the steel plate feeding process, ensuring the smoothness of the feeding.

[0055] The automatic feeding assembly 3 includes an extension frame 301 symmetrically fixed on the left and right sides of the workbench 1. The inner side of the extension frame 301 is rotatably equipped with a first conveying roller 302 and several guide rollers 303. The surface of the workbench 1 is provided with a rectangular waste collection port 401. The inner wall of the waste collection port 401 is rotatably equipped with two second conveying rollers 304.

[0056] A feeding motor 308 is fixedly connected to the back of the extension frame 301. The rotating shaft of the feeding motor 308 is fixedly connected to the end of the first conveying roller 302. Several anti-slip grooves are evenly opened on the surface of the first conveying roller 302. Several guide rollers 303 are evenly distributed on the surface of the extension frame 301.

[0057] Two second conveying rollers 304 are arranged in parallel, and the top of the second conveying rollers 304 is at the same height as the surface of the worktable 1 and the top of the first conveying roller 302, so as to realize the smooth conveying of the steel plate from the extension frame 301 to the worktable 1, ensuring that the steel plate is always in a horizontal state during the beveling process, and avoiding deviation in the straightness of the beveling process due to uneven conveying surface.

[0058] Working principle: In use, first start the lifting motor 206, which drives the lifting screw 202 to rotate, causing the lifting block 203 to move vertically up and down along the limit rod, adjusting the height of the mounting frame 204 and the milling cutter 205 so that the milling cutter 205 corresponds to the processing position of the steel plate; start the adjusting motor 601, which drives the worm gear 602 to rotate, causing the worm wheel 605 and the adjusting shaft to rotate, which in turn causes the adjusting seat 603 to rotate, adjusting the processing angle of the milling cutter 205, and keeping the angle of the milling cutter 205 stable after adjustment.

[0059] The wind turbine steel plate to be processed is placed on the first conveying roller 302 and guide roller 303 of the extension frame 301. The feeding motor 308 is started, driving the first conveying roller 302 to rotate and pushing the steel plate towards the worktable 1. At the same time, the drive motor 501 is started, driving the drive shaft 502 to rotate. On one hand, the drive motor 501 drives the second conveying roller 304 to rotate, which, together with the first conveying roller 302, realizes the automatic horizontal feeding of the steel plate, conveying the steel plate to the processing position below the milling cutter 205; on the other hand, the drive... The shaft 502 drives the driven shaft 504 to rotate via the drive synchronous pulley 503 and synchronous belt 509. The driven shaft 504 drives the linkage shaft 507 to rotate at high speed via the first transmission gear 506 and the second transmission gear 508. The linkage shaft 507 drives the guide impeller 403 to rotate at high speed inside the guide tube 402. The generated high-speed airflow enters the split air pipe 406 through the guide pipe 405 and the air inlet hose 408, and is then sprayed onto the milling processing area through the jet nozzle 407 to purge the processing area in advance and ensure that the processing area is free of impurities.

[0060] After the steel plate is conveyed to the processing position, the electric telescopic rod 305 is activated. The telescopic end of the electric telescopic rod 305 extends downward, driving the limiting pressure plate 306 and the limiting pressure roller 307 to move downward, so that the limiting pressure roller 307 presses against the upper surface of the steel plate. This, together with the second conveying roller 304, achieves clamping and limiting of the steel plate, preventing the steel plate from shifting during processing. Then, the rotary motor 604 is activated, driving the milling cutter 205 to rotate at high speed. The steel plate is continuously fed horizontally under the drive of the first conveying roller 302 and the second conveying roller 304. The milling cutter 205 mills the edge of the steel plate to form a bevel at a preset angle.
