Description

Technical Field

[0001] The utility model relates to the technical field of edge and corner rounding for machining mechanical parts, and more specifically, to an edge and corner rounding device for machining mechanical parts. Background Art

[0002] In the field of mechanical parts processing, edge and corner rounding is a common processing step, which is used to remove burrs and irregular parts on the edges of accessories to ensure the accuracy and safety of accessories. However, existing edge and corner rounding devices have certain limitations in replacing grinding heads. Due to the different materials, shapes and sizes of different mechanical accessories, grinding heads of different shapes, sizes and abrasive types are required to complete the rounding work. Most of the existing rounding devices use a fixed grinding head installation method. When replacing the grinding head, it is necessary to stop, disassemble and reinstall the machine, which is complicated and time-consuming. This not only reduces production efficiency, but also increases the downtime of the equipment, affecting the continuity and stability of the entire production process.

[0003] In addition, the inconvenience of replacing the grinding head of the existing edge and corner rounding device also has a certain impact on the quality and accuracy of mechanical parts processing. Since different mechanical parts have different requirements for rounding, such as rounding radius, surface finish, etc., it is necessary to select a suitable grinding head according to specific requirements. However, due to the difficulty in replacing the grinding head, it may not be possible to replace the appropriate grinding head in time during the processing process, resulting in unsatisfactory rounding effect, affecting the performance and life of the accessories.
