Traditional optical glass fine milling and grinding usually uses a high-speed rotation of the grinding head, combined with the relative action of the grinding liquid and the optical glass surface to achieve the purpose of fine milling and grinding. However, in the actual fine milling and grinding process, it is found that a part of the powder and grinding liquid mixed waste liquid generated by the fine milling and grinding is often retained between the grinding head and the optical glass surface, which not only affects the grinding accuracy of the optical glass, but also accelerates the loss of the grinding surface of the grinding head. For this reason, the present application proposes an optical glass fine milling and grinding head to solve the above problems. Utility Model Content

The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0027] Example

[0028] See also Figures 1 to 5 , the utility model preferably provides a technical solution:

[0029] An optical glass fine milling grinding head comprises a grinding head body 1, wherein the grinding head body 1 has a grinding surface 8 for fine milling and grinding of optical glass; a chip removal groove 7 is provided on the grinding surface 8, wherein the chip removal groove 7 is provided with a plurality of channels, and the plurality of chip removal grooves 7 are diffusely distributed from the center of the grinding surface 8 toward the surrounding areas, and the chip removal groove 7 passes through a side of the grinding head body 1 adjacent to the grinding surface 8, and drives the grinding head body 1 to rotate. During the process of grinding the optical glass by using the grinding surface 8 on the grinding head body 1, the powder and the grinding liquid mixed waste liquid generated can be poured into the chip removal groove 7 and discharged toward the surrounding areas of the grinding head body 1, thereby avoiding the phenomenon that the powder and the grinding liquid mixed waste liquid are retained between the grinding surface 8 and the optical glass, which affects the grinding accuracy of the optical glass, and improves the fine milling and grinding effect of the optical glass, while reducing the wear of the grinding surface 8, thereby improving the durability of the grinding head body 1.

[0030] In this embodiment, the ends of the multiple chip removal grooves 7 toward the middle of the grinding surface 8 are interconnected, which is conducive to the discharge of the mixed waste liquid of chips and grinding liquid from the middle of the grinding surface 8 toward the surrounding of the grinding head body 1. The chip removal groove 7 is curved in an arc shape from the center of the grinding surface 8 to the surrounding, and the curvature direction of the chip removal groove 7 is opposite to the rotation direction of the grinding head body 1, so that the mixed waste liquid of powder chips and grinding liquid can be thrown out and discharged along the curvature of the chip removal groove 7. Compared with the mixed waste liquid of powder chips and grinding liquid being thrown out and discharged along the radial direction of the grinding head body 1, the discharge radius of the mixed waste liquid of powder chips and grinding liquid is greatly reduced, which is conducive to the collection and cleaning of the thrown mixed waste liquid of powder chips and grinding liquid.

[0031] Furthermore, a connecting shaft 9 is provided on the side of the grinding head body 1 opposite to the grinding surface 8, and a mounting sleeve 2 is sleeved on the connecting shaft 9. A shaft support 3 is provided on the end face of the mounting sleeve 2, and a mounting hole 4 is opened on the shaft support 3. A positioning hole 6 is opened horizontally on the connecting shaft 9, and a positioning bolt 5 passing through the positioning hole 6 is passed through the mounting sleeve 2. The positioning bolt 5 is passed through the mounting sleeve 2 and passes through the positioning hole 6 to relatively fix the grinding head body 1 and the mounting sleeve 2, thereby the grinding head body 1 can be installed using the shaft support 3 and the mounting hole 4.

[0032] In a further embodiment, the particle size range of the grinding surface 8 is 1000-3000 mesh, which is used to achieve fine milling of optical glass. The depth of the chip groove 7 gradually increases from the middle of the grinding surface 8 to the surroundings, and the angle between the bottom wall of the chip groove 7 and the horizontal plane is 3-5°. By using this special structure, the amount of powder and grinding liquid mixed waste liquid that can be accommodated by the chip groove 7 from the middle of the grinding surface 8 to the surroundings gradually increases. During the process of guiding the composite powder and grinding liquid mixed waste liquid along the chip groove 7, the amount gradually increases from the middle of the grinding surface 8 to the surroundings, which has an excellent effect of guiding the powder and grinding liquid mixed waste liquid.

[0033] In a further embodiment, a third arc chamfer c is provided at the corner of the chip groove 7 to prevent the optical ratio surface from being scratched by the corner of the chip groove 7. A third arc chamfer c is provided at the corner of the grinding head body 1 opposite to the grinding surface 8, which conforms to the mechanical design concept. A second arc chamfer b is provided at the corner of the connecting shaft 9 to facilitate the sleeve assembly of the shaft sleeve 2.

[0034] When in use, the mounting sleeve 2 is sleeved on the connecting shaft 9, the positioning bolt 5 is penetrated through the positioning hole 6 on the mounting sleeve 2, the mounting sleeve 2 and the grinding head body 1 are relatively positioned, and then the grinding head body 1 is assembled to an axial driving device such as a motor using the shaft support 3 and the mounting hole 4, the grinding head body 1 is driven to rotate, and the optical glass is ground using the grinding surface 8 on the grinding head body 1, wherein the grinding surface 8 adopts a particle size range of 1000 to 3000 meshes, which can achieve fine milling and grinding of the optical glass. Furthermore, during the fine milling and grinding of optical glass, the powder and grinding liquid mixed waste liquid generated can be discharged from the middle of the grinding surface 8 toward the surrounding areas of the grinding head body 1 through multiple chip discharge grooves 7, thereby avoiding the phenomenon that the powder and grinding liquid mixed waste liquid is retained between the grinding surface 8 and the optical glass, affecting the grinding accuracy of the optical glass, effectively improving the fine milling and grinding effect of the optical glass, reducing the wear of the grinding surface 8, and improving the durability of the grinding head body 1. Furthermore, since the chip discharge groove 7 is curved in a circular arc toward the side opposite to the rotation direction of the grinding head body 1, the powder and grinding liquid mixed waste liquid can be thrown out and discharged along the curved arc of the chip discharge groove 7. Compared with the powder and grinding liquid mixed waste liquid being thrown out and discharged radially along the grinding head body 1, the discharge radius of the powder and grinding liquid mixed waste liquid is greatly reduced, which is beneficial to the collection and cleaning of the thrown powder and grinding liquid mixed waste liquid.
