Description

Technical Field

[0002] With the continuous growth of global demand for renewable energy, wind energy, as an important clean energy, has become a key link in the transformation of the global energy structure. Wind power generation technology has made significant progress in the past few decades. The single-unit capacity of wind turbines has continued to increase, and the power generation efficiency and reliability have also been significantly improved. One of the key components of wind turbines is castings, including core components such as wind turbine blades, nacelles, and gearboxes. These castings often face surface defects such as casting defects and surface roughness during the production process. In order to ensure the quality and surface accuracy of castings, the cleaning and polishing process is particularly important. The cleaning and polishing device can be used to clean the burrs, oxide layers, sand particles and other defects on the surface of the castings to meet the high performance and high reliability requirements of wind turbines.

[0020] The present invention provides an automatic cleaning and polishing device for large wind power castings, which has the following beneficial effects:

[0021] 1. By setting up a grinding mechanism, the fourth motor drives the grinding roller to rotate, and the oxide layer on the surface of the casting is polished and cleaned. Under the action of the first spring, the first contact wheel is also in close contact with the surface of the casting. When there is a thicker oxide layer on the surface of the casting, the first contact wheel contacts the oxide layer, drives the first abutment rod to move backward, and squeezes the elastic extrusion block through the push block, and transmits the pressure to the surface of the pressure sensor. After receiving the pressure signal, the controller drives the electric telescopic rod to move, drives the grinding roller forward, increases the pressure between the grinding roller and the casting, thereby increasing the grinding force and improving the grinding efficiency.

[0022] 2. By setting up a first auxiliary cleaning mechanism, the detergent can be synchronously sprayed onto the surface of the casting through the first water pump, which can help reduce friction and heat accumulation during the grinding process, prevent the casting surface from overheating, and dissolve some impurities in the oxide layer, helping the grinding roller to contact the surface more smoothly, thereby improving the grinding effect; and when the electric telescopic rod drives the mounting frame and the grinding roller to move toward the casting surface to increase the grinding force, it drives the driving rod to move synchronously, thereby driving the second contact plate to move, driving the tooth plate to move synchronously, and driving the first gear and the elliptical block to rotate, thereby driving the first contact plates on both sides to move away, and driving the block to move away synchronously, thereby increasing the opening of the first water pipe, increasing the flow of the detergent, and improving the cleaning effect.

[0023] 3. By setting up a second auxiliary cleaning mechanism, after the grinding roller grinds the oxide layer on the surface of the casting, as the casting rotates, the ground oxide layer rotates toward the second contact wheel. If a thick oxide layer still exists at this time, it will squeeze the second contact wheel, drive the second abutment rod to move backward, and the fourth spring is compressed, driving the second connecting plate to move backward synchronously, so that the second contact point contacts the first contact point. At this time, the second water pump works, injecting the acid solution in the second box into the second nozzle, and spraying it toward the surface of the casting from the second nozzle hole to dissolve the oxide layer, so that when the grinding roller contacts the oxide layer again, it is easier to clean and grind it, thereby improving the cleaning and grinding efficiency.

[0046] Specifically, the working principle of the large-scale wind power casting automatic cleaning and grinding device is as follows: when in use, the casting to be ground is clamped in the chuck 2 and fixed in the chuck 2 by the clamping rod 3, and then the chuck 2 is driven to rotate by the first motor 4, and the slide 604 is driven forward by the third motor 606 to make the grinding roller 613 contact with the surface of the casting, and the grinding roller 613 is driven to rotate by the fourth motor 614 to grind and clean the oxide layer on the surface of the casting. Under the action of the first spring 619, the first contact The wheel 618 is also in close contact with the surface of the casting. When there is a thick oxide layer on the surface of the casting, the first contact wheel 618 contacts the oxide layer, drives the first abutment rod 617 to move backward, and squeezes the elastic extrusion block 623 through the push block 621, and transmits the pressure to the surface of the pressure sensor 624. After receiving the pressure signal, the controller 5 drives the electric telescopic rod 615 to move, drives the grinding roller 613 to move forward, increases the pressure between the grinding roller 613 and the casting, thereby increasing the grinding force and improving the grinding efficiency.

[0047] The cleaning agent can be injected into the first nozzle 702 through the first water pump 704 and synchronously sprayed toward the surface of the casting through the first nozzle hole 703, which can help reduce friction and heat accumulation during the grinding process, while preventing the casting surface from overheating. It can also dissolve some impurities in the oxide layer, helping the grinding roller 613 to contact the surface more smoothly, thereby improving the grinding effect; and when the electric telescopic rod 615 drives the mounting frame 611 and the grinding roller 613 to move toward the casting surface to increase the grinding force, it drives the driving rod 719 to move synchronously, thereby driving the second contact plate 716 to move, driving the tooth plate 717 to move synchronously, and driving the first gear 715 and the elliptical block 713 to rotate, thereby driving the first contact plates 712 on both sides to move away, and driving the blocking block 707 to move away synchronously, thereby increasing the opening of the first water pipe 705, increasing the flow of the cleaning agent, and improving the cleaning effect.

[0048] After the grinding roller 613 grinds the oxide layer on the surface of the casting, as the casting rotates, the ground oxide layer rotates toward the second contact wheel 807. If a thick oxide layer still exists at this time, it will squeeze the second contact wheel 807, drive the second abutment rod 806 to move backward, and the fourth spring 810 is compressed, driving the second connecting plate 809 to move backward synchronously, so that the second contact point 812 contacts the first contact point 811. At this time, the second water pump 805 works, injecting the acidic solution in the second box 804 into the second nozzle 802, and spraying it toward the surface of the casting from the second nozzle 803, dissolving the oxide layer, so that when the grinding roller 613 contacts the oxide layer again, it is easier to clean and grind it, thereby improving the cleaning and grinding efficiency.

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