Description

Technical Field

[0001] This invention relates to the field of wind turbine blade processing equipment, specifically to a processing equipment for root bolts of wind turbine blades. Background Technology

[0002] With the continuous large-scale development of the wind power industry, the structural reliability and connection accuracy requirements of wind turbine blades, as the core components for wind energy capture, are increasing. As a key load-bearing connection component, the processing quality of the root bolts of wind turbine blades directly determines the connection safety and service life of the blade and hub. Therefore, high-precision and high-efficiency wind turbine blade root bolt processing equipment is needed to form and precision process the bolts.

[0003] However, existing processing equipment often uses a single fixing method during use, which cannot combine end positioning with outer wall clamping. This results in poor coaxiality of bolt clamping and insufficient clamping stability, making it easy for bolts to loosen or wobble during grinding, thus affecting the quality of bolt processing. Summary of the Invention

[0004] The purpose of this invention is to provide a processing device for root bolts of wind turbine blades. By setting a fixing part, it solves the problem that existing processing devices often use a single fixing method during use, which cannot combine the end positioning with the outer wall clamping, resulting in poor coaxiality of bolt clamping, insufficient clamping stability, and easy loosening or wobble during grinding, thus affecting the bolt processing quality.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a processing device for root bolts of wind turbine blades, comprising a support box, and further comprising: a grinding part mounted on the support box; two fixing parts, both of which are disposed within the support box; a driving part mounted on the support box; and a rotating part disposed within the support box.

A spiral groove is opened on the outer wall of the cylindrical rod. A transmission block is provided in the spiral groove. The transmission block is fixedly connected to the inner wall of the hollow shaft. A spring is sleeved on the cylindrical rod. The side of the spring closest to the cross bracket is fixedly connected to the cross bracket. The cylindrical rod is located inside the hollow shaft and is in contact with it.

[0007] Furthermore, the grinding section includes a debris collection box disposed on the inner wall of the bottom of the support box, a rectangular support plate fixedly connected to the inner wall of the rear side of the support box, and a grinding component disposed on the rectangular support plate; the front side of the support box is open, and the debris collection box and the support box are designed as drawers; the grinding component includes a mechanical arm fixedly connected to the top of the rectangular support plate, and a grinding machine is mounted on the mechanical arm.

[0008] Furthermore, the drive unit includes a guide rod fixedly connected between the left and right inner walls of the support box. Two T-shaped support rings are slidably connected to the outer wall of the guide rod. A bidirectional threaded rod is rotatably connected between the left and right inner walls of the support box. The left side of the bidirectional threaded rod passes through the left side of the support box and through the two T-shaped support rings. Both T-shaped support rings are threadedly connected to the bidirectional threaded rod. A motor is fixedly connected to the left side of the support box. The output shaft of the motor is fixedly connected to the bidirectional threaded rod via a coupling. A protective component is provided on the bidirectional threaded rod. Each circular plate is rotatably connected to two T-shaped support rings, which are located on the threads on both sides of the bidirectional threaded rod. The bidirectional threaded rod and the guide rod are arranged parallel to each other. The protective component includes several telescopic protective sleeves sleeved on the outer wall of the bidirectional threaded rod. The two telescopic protective sleeves located on the left and right sides are fixedly connected to the two T-shaped support rings on their sides that are close to each other, and the two telescopic protective sleeves located on the left and right sides that are far apart from each other are fixedly connected to the support box. There are three telescopic protective sleeves, and the left and right sides of the telescopic protective sleeve located in the middle are fixedly connected to the two T-shaped support rings, respectively.

[0009] Furthermore, the rotating part includes an L-shaped bracket fixedly connected to the left side of the guide rod located on the left side. A second motor is fixedly connected to the left side of the L-shaped bracket. The output shaft of the second motor is fixedly connected to a rotating shaft via a coupling. The right side of the rotating shaft passes through the L-shaped bracket. The rotating shaft is rotatably connected to the L-shaped bracket. The right side of the rotating shaft passes through a circular plate located on the left side. The rotating shaft is fixedly connected to the circular plate located on the left side.

[0010] Furthermore, the fixing assembly includes several limiting slide grooves formed on the cross bracket, each of the several limiting slide grooves having a slider slidably connected therein, each of the sliders being hinged to several L-shaped transmission rods, and each of the sliders being provided with a fixing member; there are four limiting slide grooves and four sliders, and the fixing member includes an arc-shaped fixing plate fixedly connected to the side of each of the sliders away from the circular plate, and an anti-slip buffer pad fixedly connected to the side of each of the arc-shaped fixing plates that are close to each other; a circular fixing plate is fixedly connected to the side of the cylindrical rod away from the circular plate; and the side of the spring away from the circular plate is fixedly connected to the circular fixing plate.

[0011] Furthermore, the robotic arm is the Dobot CR5 collaborative robot arm, which works as follows: The CR5 converts the rotation of the servo motor and reducer into end-effector pose through a 6-joint serial mechanism. Within the CC161 controller, it performs DH parameter compensation, TrueMotion dynamics, and vibration suppression to achieve high stiffness and trajectory stability. Based on the full perception fusion of vision, force control, and electronic skin, it executes a hierarchical safety strategy of collision detection and proximity perception. It supports drag teaching, trajectory recording and reproduction, and script / graphical programming. Combined with AI target detection and time-optimal path planning, it completes point-based and continuous trajectory tasks.

[0012] Furthermore, the grinding machine is a 905A4 grinding machine. Its working principle is to use compressed air as a power source. When the compressed air is turned on, the air pressure drives the blades or pistons inside the pneumatic motor, causing the pneumatic motor to rotate at high speed. Then, through the transmission device, it drives the grinding disc to rotate at high speed along a specific trajectory. The abrasive attached to the grinding disc comes into contact with the surface of the workpiece. The friction generated by the rotation removes excess material from the surface of the workpiece, such as burrs and protrusions, thereby achieving the effect of grinding and polishing, and making the surface of the workpiece smooth and flat.

[0013] The present invention has the following beneficial effects:

[0014] This invention, by setting a fixing part, allows the circular fixing plate to contact both ends of the bolt and continue to move towards each other. This causes the support frame to drive the cross bracket and the hollow shaft to slide on the cylindrical rod and compress the spring. With the cooperation of the spiral groove and the transmission block, the hollow shaft is driven to rotate. The hollow shaft drives the L-shaped transmission rod to move through the cross transmission plate, which in turn pulls the slider to slide in the limiting groove. This causes the arc-shaped fixing plate and the anti-slip buffer pad to move closer to the outer wall of the bolt. Together with the circular fixing plate, the bolt is fixed in multiple directions. This achieves the linkage triggering of clamping action and circumferential locking action. By combining the fixing method of end positioning and outer wall clamping, the coaxiality and stability of bolt clamping are significantly improved.

[0015] This invention features a drive unit. During use, the bolt is placed between two circular fixed plates. A motor drives a bidirectional threaded rod to rotate, causing the two T-shaped support rings to move closer together. The telescopic protective sleeve deforms as the T-shaped support rings move. Simultaneously, the T-shaped support rings drive the circular fixed plates to move towards each other via the circular plate, support frame, cross bracket, and cylindrical rod, achieving clamping and positioning of both ends of the bolt. This ensures stable clamping of both ends of the bolt. At the same time, the telescopic protective sleeve can effectively block grinding debris, preventing debris from adhering and affecting the operation of transmission components, thus improving the stability and service life of the device.

[0016] This invention incorporates a rotating part, which activates a robotic arm to bring the grinder into contact with the outer wall of the bolt. Simultaneously, the grinder and a second motor are activated. The second motor drives a circular plate to rotate via a shaft. The circular plate, through a support frame and a cross bracket, drives an arc-shaped fixing plate and the fixed bolt to rotate synchronously. The bolt and the grinder work together to achieve staggered grinding. The grinding position is adjusted by the robotic arm to complete the processing of the bolt. This invention achieves synchronous coordination between bolt rotation and grinding operations, forming staggered grinding to improve surface uniformity and further enhance grinding efficiency and processing quality.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The drive unit 3 includes a guide rod 311 fixedly connected between the left and right inner walls of the support box 111.

The left side of the bidirectional threaded rod 313 passes through the left side of the support box 111 and through the two T-shaped support rings 312.

The output shaft of the motor 314 is fixedly connected to the bidirectional threaded rod 313 via a coupling. A protective component is provided on the bidirectional threaded rod 313. Two circular plates 211 are rotatably connected to the two T-shaped support rings 312 respectively. The two T-shaped support rings 312 are respectively located on the double... On both sides of the threaded rod 313, the bidirectional threaded rod 313 and the guide rod 311 are arranged parallel to each other. The protective component includes several telescopic protective sleeves 315 sleeved on the outer wall of the bidirectional threaded rod 313. The two telescopic protective sleeves 315 located on the left and right sides are respectively fixedly connected to two T-shaped support rings 312 on the side closer to each other, and the two telescopic protective sleeves 315 located on the left and right sides are respectively fixedly connected to the support box 111 on the side farther from each other. There are three telescopic protective sleeves 315, and the left and right sides of the telescopic protective sleeve 315 located in the middle are respectively fixedly connected to two T-shaped support rings 312. By setting the driving part 3, the two ends of the bolt are stably clamped. At the same time, the telescopic protective sleeves 315 can effectively block grinding debris, avoid debris adhesion affecting the operation of transmission components, and improve the operating stability and service life of the device.

[0032] The rotating part 4 includes an L-shaped bracket 411 fixedly connected to the left side of the guide rod 311 located on the left side. A second motor 412 is fixedly connected to the left side of the L-shaped bracket 411. The output shaft of the second motor 412 is fixedly connected to a rotating shaft 413 via a coupling. The right side of the rotating shaft 413 passes through the L-shaped bracket 411, and the rotating shaft 413 is rotatably connected to the L-shaped bracket 411. The right side of the rotating shaft 413 passes through a circular plate 211 located on the left side, and the rotating shaft 413 is fixedly connected to the circular plate 211 located on the left side. By setting the rotating part 4, the bolt rotation and grinding operation are synchronized, forming staggered grinding to improve the surface processing uniformity and further improve grinding efficiency and processing quality.

[0033] It should be noted that the robotic arm 114, the grinder 115, the first motor 314 and the second motor 412 in this application can all be automatically controlled by inputting relevant parameters according to the program set in the control panel. The setting of this control method can be achieved by existing technology, such as PLC.

[0034] In use, the bolt is placed between the two circular fixing plates 225, and the motor 314 is started. The motor 314 drives the bidirectional threaded rod 313 to rotate. Since the bidirectional threaded rod 313 is set parallel to the guide rod 311, the bidirectional threaded rod 313 drives the two T-shaped support rings 312 to move closer to each other. During this process, the three telescopic protective sleeves 315 deform as the two T-shaped support rings 312 move, thereby preventing the debris from falling on the bidirectional threaded rod 313 during grinding. At this time, the two T-shaped support rings 312 drive the two circular plates 211 to move closer to each other. The two circular plates 211 drive the two cylindrical rods 217 to move closer to each other through the corresponding support frame 212 and cross bracket 214. The two cylindrical rods 217 drive the two circular fixing plates 225 to move closer to each other and contact the two ends of the bolt.

[0035] After both circular fixing plates 225 are in contact with both ends of the bolts, the two circular plates 211 are brought closer together. The circular plates 211, through the support frame 212, drive the cross bracket 214 and hollow shaft 213 to slide on the cylindrical rod 217. The cross bracket 214 compresses the spring 2110, causing it to deform and generate elastic force. At this time, with the cooperation of the spiral groove 218 and the transmission block 219, the transmission block 219 drives the hollow shaft 213 to rotate on the support frame 212. The hollow shaft 213 drives the cross transmission plate 215 to rotate, and the cross transmission plate 215 drives four... The L-shaped transmission rods 216 move, and since the four L-shaped transmission rods 216 are respectively hinged to the four sliders 222, and the four L-shaped transmission rods 216 are all hinged to the cross transmission plate 215, the cross transmission plate 215 pulls the four sliders 222 through the four L-shaped transmission rods 216 to slide in the corresponding limiting grooves 221 and move closer to each other. The four sliders 222 respectively drive the four anti-slip buffer pads 224 to move closer to the outer wall of the bolt through the corresponding arc-shaped fixing plates 223 and make contact with each other, and fix them to the two ends of the two circular fixing plates 225, thereby fixing the bolt.

[0036] Then, the robotic arm 114 is started, which drives the grinder 115 to contact the outer wall of the bolt. At this time, the grinder 115 and the second motor 412 are started. The grinder 115 grinds the bolt, and the second motor 412 drives the rotating shaft 413 to rotate. Since the circular plate 211 is rotatably connected to the T-shaped support ring 312, the rotating shaft 413 drives the circular plate 211 to rotate. The circular plate 211 drives the four arc-shaped fixing plates 223 to rotate through the support frame 212 and the cross bracket 214, thereby driving the fixed bolt to rotate and cooperate with the grinder 115 to form an interlaced grinding. The grinding position of the grinder 115 on the bolt is adjusted by the robotic arm 114.

[0037] The debris that falls off during polishing falls into the debris collection box 112 inside the support box 111 for collection. During cleaning, since the debris collection box 112 and the support box 111 are arranged in a drawer-like manner, the debris collection box 112 can be pulled out to clean the impurities.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
