Technical Field
[0001] The utility model relates to the technical field of grinders, in particular to a multi-angle automatic adjustment mechanism for a base of an optical curve grinder. Background Art
[0002] In modern precision manufacturing and machining, the smoothness and accuracy of workpiece surfaces are directly related to the overall performance and service life of the product. This is particularly true in areas such as high-precision mechanical parts, optical components, aerospace components, and medical devices, where extremely stringent requirements are placed on workpiece surface processing quality. Grinding machines are a key piece of equipment in achieving this goal, and their performance and flexibility directly impact machining efficiency and product quality.
[0003] Traditional grinding machines face significant technical challenges when processing workpieces with complex geometries or multi-angle grinding areas. These workpiece surfaces often contain irregular structures such as multiple slopes, grooves, and bosses, requiring the grinding tool to precisely and flexibly adjust its position and angle to accommodate the machining needs of each area. Therefore, the grinding machine base must possess highly flexible multi-angle adjustment capabilities to ensure accurate and efficient grinding.
[0004] Currently, the three-axis drive module (X, Y, and Z axes) is widely used in the market as the main adjustment mechanism for the grinding machine base. Although it meets the needs of multi-directional movement to a certain extent, it still has many limitations in practical application. First, the three-axis drive module requires high-precision synchronization and coordination between the axes, which not only increases the complexity and cost of the control system, but also places higher demands on the programmer's skill level. Precise programming requires a deep understanding of the kinematic relationship between the axes and their specific impact on the surface processing quality of the workpiece, which undoubtedly increases the difficulty of operation and training costs.
