Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding devices, and in particular to a grinding device for the production of large wind power structures. Background Technology
[0002] Large-scale wind power structures typically include tubular castings, which require grinding after forming. Existing grinding devices include a grinding device for the inner cavity of wind power castings disclosed in Chinese Utility Model Patent No. CN206047835U. This grinding device uses a combination of extension components and grinding components, which can synchronously adjust the grinding positions of several grinding components. This allows the grinding components to gradually contact the inner wall of the wind power pipe and maintain a constant friction force, ensuring that the grinding components can perform comprehensive and efficient grinding of the inner wall of the wind power pipe casting and avoiding uneven grinding.
[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: First, the aforementioned fixing assembly uses multiple clamping rods in conjunction with clamping plates to fix the grinding workpiece. Since the clamping rods cannot be adjusted synchronously, it is not only inconvenient to use, but also cannot guarantee that the adjustment amount of the clamping rods is consistent, which can easily lead to the grinding disc and the grinding workpiece not being on the same axis, thus affecting the grinding accuracy. Second, the aforementioned extension assembly requires the locking ring to be moved to separate it from the locking seat during use, and then the rotating rod is rotated to adjust the position of the grinding disc. After the adjustment is completed, the locking ring must be reset, which is very cumbersome to operate. Furthermore, the extension assembly is set on the grinding disc driven by the motor, and the extension assembly rotates with the grinding disc, so there is a motion interference problem. The power source required to move the locking ring and rotate the rotating rod is not easy to achieve. Utility Model Content
