Embodiment Construction
[0035] Taking grinding the outer cylindrical surface of a Φ240mm base disc as an example, the specific implementation method of the present invention is described. The base disc is used to generate the reference-level involute, so its roundness is very high, and it is usually expected to reach the sub-micron or even nano-scale. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0036] The universal magnetic watch base has the advantages of good rigidity, convenient use, can be clamped at any position, and the head can be rotated with a fine adjustment device. Therefore, in this example, the universal magnetic watch base 6 is selected as the clamping mechanism of the clamp body 1 . The cast iron base plate 7 is convenient for the installation of the magnetic watch seat, the asymmetrical V-shaped block 8 is used as the support of the shaft system 9, the asymmetrical V-sh...

Abstract
The invention provides an outer cylindrical surface grinding and polishing device and a using method, which belong to the technical field of precision machining. The invention has a simple structure, can cooperate with different shaft systems to realize precise grinding and polishing of the outer cylindrical surface of shaft parts or disc parts, and can process one or more workpieces of the same size at the same time. It conforms to the forming principle of the cylindrical surface, namely: the busbar revolves around the fixed axis. The outer cylindrical surface of any size can be processed, and no feeding is required during the processing. The elastic deformation of the workpiece is used to realize automatic and continuous micro-feeding, and the grinding and polishing process can be completed. The device only has straightness requirements for the working surface of the precision whetstone, and the flatness, perpendicularity and parallelism of the clamping body have little effect on the grinding and polishing process. The whetstone is not in direct contact with the clamping body to avoid damage to the whetstone due to excessive clamping force. For workpieces ground and polished by the device, the roundness error can reach the order of submicron, and the roughness can reach the order of tens of nanometers, and it has the advantages of low cost, simple operation, convenient adjustment, etc., and has important popularization and application value.
Description
technical field [0001] The invention belongs to the technical field of precision machining, and relates to a grinding and polishing processing device for the outer cylindrical surface of a part and a use method thereof. Background technique [0002] Grinding and polishing are classic ultra-precision machining techniques, which are widely used in surface finishing of metal parts, optical components and engineering ceramics. Through grinding and polishing, the processing damage caused by the previous process can be effectively removed, and an ultra-smooth and damage-free workpiece surface can be obtained. [0003] The so-called grinding refers to the method of adding the grinding liquid to the grinding tool and performing micro-processing through the relative movement of the grinding tool and the workpiece. The research tool is a hard tool with a certain rigidity. Abrasives remove trace amounts of material from the workpiece surface, resulting in a smooth, finished surface w...
