Description

Technical Field

[0001] This utility model relates to the field of glass ball grinding technology, and in particular to a high-precision grinding fixture. Background Technology

[0002] Small ball grinding refers to the process of rounding small ball blanks in a small ball ring polisher. A grinding ring filled with small balls is placed between a worktable lined with soft white paper and the grinding dish for grinding. Because assembling and disassembling the grinding dish is cumbersome, the weight distribution of the grinding ring is uneven, resulting in low work efficiency. Furthermore, since all the small balls are fixed with a single grinding ring, it's equivalent to grinding all the balls as a whole. If a dimensional deviation occurs on one side of the grinding process, it can cause deviations in the dimensions of other balls, leading to low dimensional accuracy and a low yield rate. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the existing technology and provide a high-precision grinding fixture.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A high-precision grinding fixture includes a handle, a grinding vessel body, an upper grinding sleeve for small balls, a lower grinding sleeve for small balls, a grinding ring for small balls, and a worktable. The upper grinding sleeve for small balls is placed on the lower grinding sleeve for small balls, and the two are tightened and fixed together with M4 bolts. The lower grinding sleeve for small balls is placed on the worktable. The handle is fixed to the grinding vessel body with M5 bolts. The grinding vessel body is inserted from the top into the hole between the upper and lower grinding sleeves for small balls. The grinding ring for small balls is placed between the grinding vessel body and the worktable and is pressed down by the grinding vessel body. The grinding ring for small balls has multiple independent inner holes, and each inner hole holds a small ball to be ground.

[0006] Furthermore, soft white paper is glued to both the top of the workbench and the bottom of the grinding bowl.

[0007] Furthermore, the M4 bolt is an M4 cylindrical head internal hex bolt.

[0008] Furthermore, the M5 bolt is an M5 cylindrical head internal hex bolt.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] This invention improves work efficiency and ensures more uniform force on the grinding balls during grinding by designing a high-precision grinding fixture. The multiple independent inner holes on the grinding ring separate the balls into several independent units. If one ball deviates, it will not affect the other balls within the grinding ring, thus improving the precision and yield of the grinding balls, effectively reducing ball scrap and lowering production costs. Furthermore, the high-precision grinding fixture is easy to assemble and disassemble, requiring only bolts, reducing time wasted on assembly and disassembly. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0020] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] Example

[0022] like Figure 1 and 2 As shown, a high-precision grinding fixture includes a handle 2, a grinding vessel body 3, an upper grinding sleeve 5, a lower grinding sleeve 6, a grinding ring 9, and a worktable 10. The upper grinding sleeve 5 is placed on the lower grinding sleeve 6, and the two are fixed together by M4 bolts 7. Two M4 bolts 7 are M4 cylindrical head hexagonal socket head cap screws, which are screwed into holes on both sides of the bottom of the lower grinding sleeve 6 and tightened. The lower grinding sleeve 6 is placed on the worktable 10. The handle 2 is fixed to the grinding vessel by M5 bolts 1. On the main body 3, there are two M5 bolts 1, which are M5 cylindrical head hexagonal socket head cap screws, which are screwed in and tightened from the holes on both sides above the handle 2; the grinding disc body 3 is placed from the top into the hole between the upper grinding sleeve 5 and the lower grinding sleeve 6 of the small ball; the small ball grinding ring 9 is placed between the grinding disc body 3 and the worktable 10 and is pressed down by the grinding disc body 3; the small ball grinding ring 9 is provided with multiple independent inner holes, and a small ball 8 to be ground is placed in each inner hole; soft white paper 4 is glued to the top of the worktable 10 and the bottom of the grinding disc body 3.

[0023] First, soft white paper 4 is glued to the top of the workbench 10 (not shown in the figure) and the bottom of the grinding bowl body 3. Then, the upper grinding sleeve 5 and the lower grinding sleeve 6 of the small ball are fixed. The small ball 8 to be ground is filled into the inner hole of the small ball grinding ring 9. Then, the small ball grinding ring 9 is placed into the hole of the upper grinding sleeve 5 and the lower grinding sleeve 6 of the small ball. Then, the handle 2 is lifted and the fixed grinding bowl body 3 is placed into the hole of the lower grinding sleeve 6 of the small ball from the top, and the small ball grinding ring 9 is pressed on the workbench 10.

[0024] This invention improves the precision and yield of grinding balls 8 while also increasing work efficiency. By using a high-precision grinding fixture, all balls 8 are ground evenly under pressure. The multiple independent inner holes on the ball grinding ring 9 divide the balls 8 into several independent units. If one ball 8 deviates, it will not affect the other balls within the grinding ring 9, thus improving the precision and yield of the grinding balls 8. The modified structure of the high-precision grinding fixture increases its weight, further improving the uniformity of the grinding force on the balls 8. This effectively reduces the scrap rate of balls 8, lowers production costs, and minimizes time wasted on assembly and disassembly.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
