Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation, and in particular relates to a main shaft blank burr grinding mechanism. Background Art

[0002] The main shaft in wind power generation refers to the fixed shaft of the wind turbine, also called the wind wheel shaft or rotor shaft. The fixed shaft is the main component connecting the wind wheel and the generator of the wind turbine. It bears the force of the wind wheel blades and transmits it to the generator. After the production and processing of the fixed shaft, the burrs on the edge of the fixed shaft blank need to be polished to avoid sharp or irregular burrs on the edge of the fixed shaft blank.

[0003] In the prior art, when grinding the fixed-axis blank, the edge of the fixed-axis blank is generally ground by means of the vertical pole and the connecting plate moving on the surface of the vertical pole, and the grinding block on the connecting plate is used to grind the edge of the fixed-axis blank, and the height of the connecting plate is adjusted up and down by the vertical pole, so as to adjust the grinding angle. However, although the fixed-axis blank can be ground by the grinding block, when the grinding block is used to grind the fixed-axis blank, the friction between the abrasive and the surface of the fixed-axis blank will peel off or grind some iron filings on the surface of the fixed-axis blank and debris impurities on the surface of the abrasive, and these iron filings and impurities will fall to the ground due to friction. If they are not cleaned up in time, their long-term accumulation will affect the subsequent processing environment. Utility Model Content

[0022] A guide rod 13 is provided in the collecting box 8 and at the top of the first screw rod 10. The top of the electromagnetic suction cup 11 is slidably sleeved on the top of the guide rod 13. A first motor 14 is provided on the surface of the partition 9. The output shaft of the first motor 14 rotates through the partition 9 and is connected to the first screw rod 10. The moving direction of the electromagnetic suction cup 11 is guided by the guide rod 13 to enhance the stability of the movement of the electromagnetic suction cup 11.

[0023] A fan 15 is provided in the collecting box 8, and the output end of the fan 15 passes through the partition 9. A filter 16 is screwed to the connection point between the output end of the fan 15 and the partition 9 through bolts. The gas drawn into the collecting box 8 is filtered by the filter 16 to prevent impurities and iron filings in the drawn gas from entering the fan 15 when the fan 15 is working.

[0024] The grinding assembly 6 includes a vertical rod 17, in which a second screw rod 18 is rotatably connected. A second motor 19 is provided on the top of the vertical rod 17, and the output shaft of the second motor 19 is fixedly connected to the second screw rod 18. When the second motor 19 rotates, it can drive the second screw rod 18 to rotate.

[0025] The surface of the second screw rod 18 is connected to a connecting plate 20 through a screw nut, and one end of the connecting plate 20 is slidably connected to the vertical rod 17. The other end of the connecting plate 20 movably penetrates the vertical rod 17, and a third motor 21 is provided on the surface of the connecting plate 20. A grinding block 22 is provided on the output shaft surface of the third motor 21. When the third motor 21 is working, it drives the grinding block 22 to rotate, so that the burrs on the edge of the fixed axis body 5 are polished by the rotating grinding block 22.

[0026] A latch 23 is provided on the surface of the upper arc block 4 and the latch 23 is plugged into a latch hole provided on the surface of the fixing frame 2. A collecting bucket 24 is provided on the top of the collecting box 8. When it is necessary to grind the other side of the fixed axis body 5, the latch 23 can be disengaged from the latch hole, thereby flipping the upper arc block 4 so that the upper arc block 4 is disengaged from the clamping of the fixed axis body 5, thereby adjusting the angle of the fixed axis body 5 that needs to be ground.

[0027] The spindle blank burr grinding mechanism, when it is necessary to grind the fixed shaft body 5, the upper arc block 4 is flipped to one side, so that the fixed shaft body 5 can be placed on the lower arc block 3, and the upper arc block 4 is flipped back to make the pin 23 on the surface of the upper arc block 4 plug into the pin 23 hole on the surface of the fixing frame 2, so that the fixed shaft body 5 is clamped and fixed between the lower arc block 3 and the upper arc block 4, and the third motor 21 is started, and the third motor 21 drives the grinding block 22 to rotate to grind the burrs on the edge of the fixed shaft body 5 When the grinding height of the grinding block 22 needs to be adjusted, the second motor 19 is started, and the second motor 19 rotates forward to drive the second screw rod 18 to rotate, so that the connecting plate 20 moves upward in the vertical rod 17 to adjust the grinding height of the grinding block 22. When the second motor 19 is reversed, it drives the second screw rod 18 to rotate in the reverse direction, so that the connecting plate 20 moves downward in the vertical rod 17 to lower the grinding height of the grinding block 22, which meets different grinding needs, is more convenient to use and has higher grinding efficiency.

[0028] The burrs on the edge of the fixed axis body 5 are ground by the grinding block 22, and the iron filings and impurities that fall after grinding fall into the collecting bucket 24 at the bottom of the grinding block 22. Under the action of the fan 15, the iron filings and impurities in the collecting bucket 24 are drawn into the collecting box 8, so that the iron filings and impurities that fall after grinding are collected, and the electromagnetic suction cup 11 is energized while collecting, and the electromagnetic suction cup 11 generates magnetic force to absorb the iron filings in the collecting box 8. When the remaining iron filings are accumulated in the impurities and dust in the collecting box, the first motor 14 is started to work, driving the first screw rod 10 to rotate, and the first screw rod 10 drives the electromagnetic suction cup 11 driven by the screw nut to move left and right, and the first screw rod 10 drives the electromagnetic suction cup 11 driven by the screw nut to move left and right. The brush 12 at the bottom of the electromagnetic suction cup 11 sweeps the dust and impurities, and the iron filings in the dust and impurities are adsorbed by the electromagnetic suction cup 11 after sweeping. When the dust and impurities in the collection box 8 are cleaned later, the sealing door on the surface of the collection box 8 is opened, and the collection box is manually taken and placed in the bottom of the electromagnetic suction cup 11, and the electromagnetic suction cup 11 is powered off. The electromagnetic suction cup 11 loses its magnetic force, and the iron filings adsorbed on the electromagnetic suction cup 11 fall off from the electromagnetic suction cup 11 and fall into the collection box in the absence of magnetic force, thereby collecting the iron filings, and then manually cleaning the remaining impurities and dust in the collection box. The cleaning is more convenient and it is easy to separate the iron filings in the dust, and it is more convenient to use.

[0029] The utility model can manually adjust the first motor 14, the second motor 19, and the third motor 21 by correspondingly connecting switch buttons, such as switches for controlling forward and reverse rotation of the motors. Intelligent control can also be adopted, such as connecting to Siemens PLC or single-chip microcomputer STM32 for control. Since they are all existing control technologies, they will not be described in detail here.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
