Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to an annular seam grinding device for processing a wind power tower barrel. Background Art

[0002] The wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the set. The production process of wind turbine tower is generally as follows: CNC cutting machine unloads, thick plates need to be beveled, and after the plate rolling machine rolls the plate into shape, spot welding, positioning, and confirmation are carried out to weld the inner and outer longitudinal seams. After the roundness inspection, if there is a problem, a secondary rounding is carried out. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, non-destructive testing and flatness inspection of the weld are carried out, sandblasting and painting are carried out, and after the internal parts are installed and the finished product inspection is completed, it is transported to the installation site.

[0003] After the cylinder of a wind power tower is welded, an annular seam will be generated at the welding position. The existence of the annular seam greatly affects the overall appearance of the cylinder, and the existence of the annular seam will also cause a series of unstable situations. Therefore, no matter from which angle, the annular seam needs to be polished. When the grinding device in the prior art is grinding the annular seam, it can only rely on manual labor to reduce the thickness of the annular seam little by little. Due to the lack of necessary adjustment structure, it is easy to have uneven grinding thickness. For this reason, we provide an annular seam grinding device for processing a wind power tower cylinder that can perform precise grinding. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a circumferential seam grinding device for processing a wind power tower cylinder to solve the technical problems mentioned in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an annular seam grinding device for processing a wind power tower cylinder, comprising an outer ring, a grinding assembly is installed on the inner side of the outer ring, and the grinding assembly comprises a fixed block and a grinding block, a groove is provided on the inner end face of the outer ring, and an electric guide rail is installed inside the groove, a slider adapted to the electric guide rail is sleeved on the outer wall of the electric guide rail, and the slider is slidably connected to the inner wall of the groove, the outer wall of the slider is fixedly connected to a connecting rod, and the end of the connecting rod is fixedly connected to the outer wall of the fixed block.

[0006] By adopting the above technical solution, the grinding block can be adjusted to ensure the accuracy of the annular seam grinding, that is, to improve the quality and efficiency of the grinding.

[0007] The utility model is further configured that an adjustment structure is installed on the outer wall of the grinding block.

[0008] By adopting the above technical solution, the grinding block can be adjusted.

[0009] The utility model is further configured such that the adjustment structure includes an adjustment bolt connected to the outer wall of the grinding block through a bearing, and the adjustment bolt passes through the fixed block and extends above the fixed block, and a threaded wall adapted to the thread of the outer wall of the adjustment bolt is opened in the inner wall of the fixed block.

[0010] By adopting the above technical solution, the grinding block can be adjusted.

[0011] The utility model is further configured that a limiting sleeve is arranged at the top end of the fixing block and located outside the adjusting bolt, and a return spring installed on the inner wall of the outer ring is connected to the top end of the limiting sleeve.

[0012] By adopting the above technical solution, the movement and resetting of the limiting sleeve are assisted.

[0013] The utility model is further configured that a bolt head is fixed to the top end of the adjusting bolt, and a limiting groove for engaging and limiting the bolt head is provided on the inner wall of the limiting sleeve outside the bolt head.

[0014] By adopting the above technical solution, a limiting and engaging effect is achieved on the adjusting bolt.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] 1. The utility model sets an adjustment structure. First, the annular seam of the cylinder to be polished is placed at the center position of the inner side of the outer ring. Then, by rotating the adjusting bolt, the adjusting bolt moves under the action of the threaded wall, and then pushes the polishing block to move until the polishing block moves to the annular seam position. Then, the electric guide rail is started, and the electric guide rail drives the slider to move. The movement of the slider drives the fixed block to move through the connecting rod, and the fixed block drives the polishing block to move to realize the polishing of the annular seam. The operation of the electric guide rail is stopped until no waste chips are generated. At this time, the adjusting bolt can be further adjusted to further polish the annular seam. The above steps are repeated until all the annular seams are polished to complete the polishing operation of the annular seam of the cylinder. Through the above structure, the precise thickness control of the annular seam during polishing is realized, thereby improving the quality and efficiency of polishing.

[0017] 2. The utility model provides a limiting sleeve. After the adjustment of the adjusting bolt is completed, the limiting sleeve and the limiting groove on the inner wall are used to achieve the engagement and limitation of the bolt head of the adjusting bolt, that is, to achieve the limitation of the adjusting bolt, thereby ensuring the stability of the position of the grinding block and thus ensuring the stability of the grinding process.
