Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine hub processing equipment, and in particular relates to a polishing device after the melting of wind turbine hubs. Background Technology

[0002] The wind turbine hub is one of the core components of a wind turbine generator set. Its main function is to connect the blades to the main shaft, convert the wind energy captured by the blades into mechanical energy, and then transmit it to the generator through the main shaft to generate electricity.

[0003] After the wind turbine hub is formed, its surface needs to be polished. Existing handheld polishing equipment requires pressing the polishing equipment to maintain sufficient pressure between the polishing disc and the hub. Applying pressure is physically demanding for the workers, thus making conventional polishing equipment physically demanding.

[0004] To address this issue, we propose a polishing device for the smelting of wind turbine hubs. Utility Model Content

[0005] The purpose of this invention is to solve the problem that conventional polishing equipment is physically demanding, and to propose a polishing device for the smelting of wind turbine hubs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A polishing device for wind turbine hubs after smelting includes a turntable. An elastic sponge is fixedly connected to the lower end of the turntable, and sandpaper is fixedly connected to the lower end of the elastic sponge. A pressure strip is rotatably mounted on the upper part of the turntable, and a magnet box is fixedly connected to the side end of the pressure strip. Ball bearings are rolled between the pressure strip and the turntable. The turntable is mounted on a target electric drill, which drives the turntable to rotate. The turntable drives the elastic sponge to rotate, which in turn drives the sandpaper to rotate, pressing the sandpaper onto a flat area of ​​the target wind turbine hub. The magnet box attracts the sandpaper to the wind turbine hub, providing a downward force to the pressure strip. The ball bearings act on the turntable, which in turn acts on the elastic sponge and sandpaper, reducing the operator's workload.

[0008] Preferably, a lid is slidably inserted into the upper end of the magnet box, and the end of the lid facing away from the magnet box is fastened to the retaining strip. The lid is inserted into the magnet box to shield the upper opening of the magnet box.

[0009] Preferably, the turntable includes a docking post, the lower end of which is fixedly connected to a disc body. A retaining ring is fixedly connected to the lower part of the docking post, and a ball bearing ring is fixedly connected to the upper part of the disc body, the ball bearing ring being sleeved on the outside of the docking post. The docking post is installed on the target drilling rig, and the drilling rig drives the docking post to rotate. The docking post, in turn, drives the retaining ring, ball bearing ring, and disc body to rotate, causing the disc body to rotate the elastic sponge and sandpaper, allowing the sandpaper to rub along the surface of the target wheel hub, facilitating the grinding of the wheel hub surface.

[0010] Preferably, the pressure strip includes a rotating ring, and strips are symmetrically and fixedly connected to the outside of the rotating ring. When the side of the strip is subjected to downward pressure, the rotating ring acts downward on the ball bearings, which in turn act downward on the ball bearing ring. The rolling action of the ball bearings between the rotating ring and the ball bearing ring prevents the turntable from driving the pressure strip to rotate at high speed.

[0011] Preferably, the magnet box includes a box body, inside which a magnet block is installed. A fixed shaft is fixedly connected to the lower part of the box body, and a roller is rotatably mounted on the fixed shaft. The magnet block attracts the target wheel, and through the action of the magnet block on the box body, the box body acts downwards on the strip, facilitating the application of pressure to the strip.

[0012] Preferably, the lid includes a cover body, one end of which is fixedly connected to a fastener. After the magnet is placed inside the box body, the lid body is inserted into the box body, so that the fastener is fastened to the strip, and the lid body blocks the magnet, preventing the magnet from detaching from the box body.

[0013] Preferably, the lid also includes a pull button, which is symmetrically and fixedly connected to the side of the lid. By squeezing the pull button and pulling the lid outward, the top of the box is opened, the magnet can be taken out, and a new magnet can be placed in, making it convenient to replace the magnet.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. Install the turntable on the target electric drill. The drill drives the turntable to rotate, which in turn drives the elastic sponge to rotate, which in turn drives the sandpaper to rotate. Press the sandpaper onto a flat area of ​​the target wind turbine hub and use the magnet box to attract it to the wind turbine hub. The magnet box provides a downward force to the pressure bar, which acts on the turntable through the ball bearings. The turntable acts on the elastic sponge and sandpaper, reducing the operator's workload.

[0016] 2. Install the docking post on the target drilling rig. The drilling rig drives the docking post to rotate, which in turn drives the retaining ring, ball ring, and disc to rotate. The disc then drives the elastic sponge and sandpaper to rotate, allowing the sandpaper to rub along the surface of the target wheel hub, making it easier to polish the wheel hub surface.

[0017] 3. When the side of the strip is subjected to downward pressure, the rotating ring acts downward on the ball, which in turn acts downward on the ball ring. The rolling action of the ball between the rotating ring and the ball ring prevents the turntable from driving the pressure strip to rotate at high speed.

[0018] 4. Use the magnet to attract the target wheel hub. The magnet acts on the box, causing the box to act downward on the strip, which facilitates the application of pressure to the strip.

[0019] 5. After placing the magnet inside the box, insert the lid onto the box so that the latch is secured to the strip. Use the lid to block the magnet and prevent it from detaching from the box. Attached Figure Description

[0032] like Figure 1 and 5 As shown, the lid 5 includes a lid body 51, with a fastener 53 fixedly connected to one end of the lid body 51. The lid body 51 is inserted into the box body 41, and the fastener 53 is fastened to the strip 32. After the magnet 42 is placed inside the box body 41, the lid body 51 is inserted into the box body 41, so that the fastener 53 is fastened to the strip 32. The lid body 51 blocks the magnet 42, preventing the magnet 42 from detaching from the box body 41.

[0033] like Figure 1 and5 As shown, the lid 5 also includes a pull button 52, which is symmetrically and fixedly connected to the side of the lid 51.

[0034] Working principle: The turntable 2 is installed on the target electric drill. The electric drill drives the turntable 2 to rotate, which in turn drives the elastic sponge 1 to rotate. The elastic sponge 1 drives the sandpaper 6 to rotate, pressing the sandpaper 6 onto the flat part of the target wind turbine hub. The magnetic box 4 attracts the sandpaper to the wind turbine hub, and the magnetic box 4 provides a downward force to the pressure strip 3. The ball bearing 7 acts on the turntable 2, and the turntable 2 acts on the elastic sponge 1 and the sandpaper 6.
