Description

Technical Field

[0001] This utility model relates to the field of wind turbine parts processing technology, specifically to a wind turbine parts grinding device. Background Technology

[0002] The main purpose of grinding wind turbine components is to remove surface burrs, sharp edges, and unevenness to improve the precision and surface smoothness of the components. This ensures better cooperation with other parts and guarantees the normal operation and efficient functioning of the wind turbine. For example, the impeller of a wind turbine may require welding or assembling different components during manufacturing. Welding produces weld slag and spatter. The internal structure of the impeller is often complex, and the welding process may produce some small weld slag, spatter, or irregular welding marks. Automated cleaning equipment may not be able to completely remove these weld slag or uneven parts, so manual operation is required to ensure that every corner and detail is effectively cleaned. Currently, when manually grinding impellers, clamps or manual holding are generally used to fix the impeller in place. Then, grinding is performed. However, during the grinding process, multiple surfaces of the impeller need to be ground. Therefore, a drive component that can rotate the clamps and other structures may be required, which increases the cost. Also, the area where the impeller is held by the clamp is covered by the clamp and cannot be ground. The impeller may need to be removed from the clamp and adjusted before the area where it was initially held can be ground. The overall operation is relatively inconvenient and will affect the actual grinding efficiency. Manually holding the impeller is relatively unstable and may cause wobbling and displacement during the grinding process, which will affect the grinding effect. At the same time, it is inconvenient to quickly rotate and adjust the position of the impeller by manually holding it, which will also affect the grinding efficiency.

[0003] In view of this, we propose a grinding device for wind turbine components. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a grinding device for fan accessories, including a bracket, a guide groove is provided on one side of the bracket, two sets of sliders are slidably installed inside the guide groove, and limit rollers are rotatably installed on the inner sidewalls of the two sets of sliders, and the two sets of limit rollers are symmetrically distributed.

[0007] Two sets of limiting rings are slidably installed on the surfaces of both sets of limiting rollers, and multiple sets of ball bearings are movably connected to the side of the two sets of limiting rings that are close to each other.

[0008] The two sets of limiting rollers are equipped with a first driving component at one end, and a second driving component is also provided inside the two sets of limiting rollers.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] A grinding device for fan parts includes a bracket 1. A guide groove 5 is provided on one side of the bracket 1. Two sets of sliders 6 are slidably installed inside the guide groove 5. Limiting rollers 8 are rotatably installed on the inner sidewalls of the two sets of sliders 6. The two sets of limiting rollers 8 are symmetrically distributed. Two sets of limiting rings 10 are slidably installed on the surface of the two sets of limiting rollers 8. Multiple sets of balls 14 are movably connected to the side of the two sets of limiting rings 10 that are close to each other. A first driving member is provided at one end of the two sets of limiting rollers 8, and a second driving member is also provided inside the two sets of limiting rollers 8.

[0026] Specifically, firstly, based on the size of the impeller, the distance between the two sets of limiting rollers 8 can be adjusted by the first driving component, thereby allowing the two sets of limiting rollers 8 to better support and limit the bottom of the impeller. Simultaneously, the guide groove 5 and the two sets of sliders 6 inside the guide groove 5 can make the two sets of limiting rollers 8 more stable during movement. After the positions of the two sets of limiting rollers 8 are adjusted, the impeller can be placed between the two sets of limiting rollers 8. Then, the position of the limiting rings 10 on the two sets of limiting rollers 8 is adjusted by the second driving component, so that the limiting rings 10 can support the two sides of the impeller. Limiting the impeller prevents it from shifting during the grinding process. Two sets of rotatable limiting rollers 8 and ball bearings 14 on the limiting ring 10 allow for quick rotation and position adjustment of the impeller after it has been limited. The ball bearings 14 are made of rubber, facilitating impeller rotation and limiting while preventing wear on the impeller surface. After limiting the impeller, workers only need to provide simple support and position adjustment, effectively improving the efficiency of impeller grinding.

[0027] Specifically, the first driving component includes two sets of limiting rollers 8, one end of which is rotatably mounted with a first threaded sleeve 11. The inner cavity sidewalls of the two sets of first threaded sleeves 11 are threadedly connected to a first bidirectional lead screw 3. The inner cavity sidewall of the bracket 1 is provided with a first sliding groove 2. The inner cavity sidewall of the first sliding groove 2 is rotatably mounted to one end of the first bidirectional lead screw 3. The other end of the first bidirectional lead screw 3 rotates through the first sliding groove 2, and a first handwheel 4 is also fixedly mounted at the end of the first bidirectional lead screw 3 that passes through the first sliding groove 2. The second driving component includes two sets of limiting rollers 8, the inner cavity sidewalls of which are rotatably mounted with a first threaded sleeve 11. The two sets of second bidirectional lead screws 12 are movably installed. The other end of each set of second bidirectional lead screws 12 rotates through the limiting roller 8. The end of each set of second bidirectional lead screws 12 that passes through the limiting roller 8 is fixedly installed with a second handwheel 7. The surfaces of each set of second bidirectional lead screws 12 are threadedly connected with a second threaded sleeve 13. The surfaces of each set of limiting rollers 8 are provided with two sets of second sliding grooves 9. The inner cavity sidewalls of each set of second sliding grooves 9 are slidably connected to the surfaces of two sets of limiting rings 10. The inner cavity sidewalls of each set of limiting rings 10 are fixedly installed on the surface of the second threaded sleeve 13.

[0028] Specifically, by rotating the first handwheel 4, the first bidirectional lead screw 3 in the first slide groove 2 can be rotated, thereby driving the two sets of first threaded sleeves 11 on the surface of the first bidirectional lead screw 3 to move in opposite directions. At this time, the limiting rollers 8 installed on one side of the two sets of first threaded sleeves 11 can be moved synchronously. By rotating the two sets of second handwheels 7 respectively, the second bidirectional lead screws 12 in the two sets of limiting rollers 8 can be rotated, thereby driving the limiting ring 10 in the second slide groove 9 to move through the second threaded sleeve 13 on the surface of the second bidirectional lead screw 12.

[0029] The working principle of this utility model is as follows: First, based on the size of the impeller, rotating the first handwheel 4 drives the first bidirectional lead screw 3 in the first slide groove 2 to rotate, thereby driving the two sets of first threaded sleeves 11 on the surface of the first bidirectional lead screw 3 to move in opposite directions. At this time, the limiting rollers 8 installed on one side of the two sets of first threaded sleeves 11 can be moved synchronously, so that the two sets of limiting rollers 8 can better support and limit the bottom of the impeller. At the same time, the guide groove 5 and the two sets of sliders 6 inside the guide groove 5 can make the two sets of limiting rollers 8 more stable during the movement. After the positions of the two sets of limiting rollers 8 are adjusted, the impeller can be placed between the two sets of limiting rollers 8. Then, by rotating the two sets of second handwheels 7 respectively, the second bidirectional lead screws 11 in the two sets of limiting rollers 8 can be driven to move in opposite directions. The rod 12 rotates, thereby driving the limiting ring 10 in the second slide groove 9 to move through the second threaded sleeve 13 on the surface of the second bidirectional lead screw 12. This allows the limiting ring 10 to limit the impeller on both sides, preventing the impeller from shifting during the grinding process. At the same time, the two sets of rotatable limiting rollers 8 and the ball bearings 14 on the limiting ring 10 facilitate quick rotation of the impeller after it has been limited, allowing for adjustment of its position. The ball bearings 14 are made of rubber, which facilitates the rotation of the impeller and limits its position while preventing wear on the impeller surface. After the impeller is properly limited, the operator only needs to provide simple support and position adjustment, effectively improving the efficiency of impeller grinding.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
