Description

Technical Field

[0001] This utility model relates to a planetary wheel for polishing optical glass, belonging to the field of planetary wheel technology. Background Technology

[0002] Planetary wheels are fixtures used in various flat surface polishing processes such as glass, lenses, silicon wafers, and hard drives. They are also known as polishing jigs or polishing pads. The surface of the planetary wheel is provided with workpiece grooves for placing the workpiece to be polished, and the shape of the workpiece to be polished is completely consistent with that of the workpiece.

[0003] Previously, only the top and bottom surfaces of the product were polished. However, some strip-shaped products require polishing of all four surfaces: the top and bottom surfaces and the front and back surfaces. If the existing planetary wheel is used, the inner wall of the workpiece groove will be in complete contact with the polishing surfaces of the front and back surfaces of the product. During the polishing process, the polishing surfaces of the front and back surfaces will collide with the inner wall of the planetary wheel workpiece groove, resulting in scratches and edge chipping. The glass fragments generated by the chipping will circulate in the polishing machine, thus affecting the polishing quality of the top and bottom surfaces of the product.

[0004] Therefore, in order to improve the scratches and edge chipping problems in the effective area of ​​the polished surface of the product during the processing, there is an urgent need for a planetary wheel for polishing optical glass. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a planetary wheel for polishing optical glass. By setting a fixed section and a clearance section in the product positioning groove, when the product is placed in the product positioning groove, the surface of the product that does not need to be polished can contact the fixed section, while the surface that needs to be polished can be placed in the clearance section. This ensures that the effective area of ​​the product can avoid contact with the planetary wheel during polishing, thereby avoiding scratches and chipping caused by collision between the product and the inner wall of the product positioning groove.

[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:

[0007] A planetary wheel for polishing optical glass includes a planetary wheel body, a product positioning groove, and a fixing hole, wherein...

[0008] The product positioning groove is provided through the planetary wheel body, and there are multiple product positioning grooves, which are distributed around the planetary wheel body.

[0009] The fixing hole is provided through the middle of the planetary wheel body;

[0010] The product positioning groove includes a fixed section and a clearance section. There are two fixed sections and two clearance sections. The two fixed sections are parallel and the two clearance sections are symmetrically arranged. The fixed sections are connected to the clearance sections. After the product is placed in the product positioning groove, it only contacts the fixed sections and does not contact the clearance sections.

[0011] Furthermore, it also includes a positioning hole, which is disposed through the planetary wheel body.

[0012] Furthermore, it also includes a raised strip, which is fixed to the fixed section.

[0013] Furthermore, it also includes a reinforcing ring, which is fixed circumferentially to the planetary wheel body.

[0014] Furthermore, each fixed segment has multiple protrusions.

[0015] Furthermore, it also includes a wear-resistant ring, which is embedded in the middle of the planetary wheel body.

[0016] Furthermore, it also includes a diamond coating, which is fixed to the planetary wheel body.

[0017] Furthermore, the avoidance section is arc-shaped.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0019] The planetary wheel for polishing optical glass provided by this utility model has a fixed section and a clearance section set in the product positioning groove. When the product is placed in the product positioning groove, the surface of the product that does not need to be polished can contact the fixed section, while the surface that needs to be polished can be placed in the clearance section. This ensures that the effective area of ​​the product can avoid contact with the planetary wheel during polishing, thereby avoiding scratches and chipping caused by collision between the product and the inner wall of the product positioning groove.

[0026] like Figure 1 As shown, this embodiment provides a planetary wheel for polishing optical glass, including a planetary wheel body 1, a product positioning groove 2, and a fixing hole 3, wherein...

[0027] The product positioning groove 2 is provided through the planetary wheel body 1, and there are multiple product positioning grooves 2, which are distributed around the planetary wheel body 1.

[0028] The fixing hole 3 is provided through the middle of the planetary wheel body 1;

[0029] The product positioning groove 2 includes a fixed section 201 and a clearance section 202. There are two fixed sections 201 and two clearance sections 202. The two fixed sections 201 are parallel and the two clearance sections 202 are symmetrically arranged. The fixed section 201 and the clearance section 202 are connected. After the product is placed in the product positioning groove 2, it only contacts the fixed section 201 and does not contact the clearance section 202.
