Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a polishing fixture. Background Art

[0002] Traditional single-sided polishing fixtures generally adopt a design with the west side higher and the east side lower. This design not only increases the complexity of the operation process, requires operators to accurately distinguish the front and back positions of the product, but also needs to extend the polishing time to improve the qualified rate of interference fringes, significantly increasing the labor cost and operation difficulty.

[0003] At the same time, the production cycle of traditional polishing machines is long, accompanied by a long-term and high-intensity training requirement for operators. In addition, operators need to maintain a high degree of concentration during the polishing process, resulting in a production efficiency and a qualified rate of interference fringe quality of only about 90%.

[0004] In addition, although high-precision fixtures can ensure a certain machining accuracy, their high manufacturing cost and short service life cannot be ignored. Moreover, the height difference between the polished products is obvious, further increasing the overall production cost. Therefore, there is an urgent need for a more efficient, economical and easy-to-operate polishing fixture design scheme to overcome the above technical limitations and improve the quality and efficiency of glass polishing. Summary of the Utility Model

[0005] To solve at least one of the above technical problems, the utility model provides a polishing fixture.

[0006] To achieve the above object, the embodiments of the present application adopt the following technical solutions:

[0007] A polishing fixture provided by the utility model includes:

[0008] A fixture body, the fixture body is in a strip-shaped sheet structure, the fixture body includes a loading surface for loading products and an overflow port, the loading surface is a plane and the area of the loading surface is larger than the area of any adjacent surface of the loading surface, and the overflow port is located at the edge of the loading surface.

[0009] In a possible implementation manner of the present application, the cross-sectional shape of the fixture body is a rectangle.

[0010] In a possible implementation manner of the present application, a fixing part is arranged in the middle of the loading surface.

[0011] In a possible implementation manner of the present application, the fixture body includes at least two of the overflow ports.

[0012] In a possible implementation manner of the present application, the two overflow ports are respectively arranged at both ends of the fixture body.

[0013] In a possible implementation manner of the present application, the overflow port is provided at one of the corners of the fixture body.

[0014] In a possible implementation manner of the present application, the overflow port is provided on one of the sides of the fixture body.

[0015] In a possible implementation manner of the present application, the overflow port is arc-shaped.

[0016] In a possible implementation manner of the present application, the overflow port is provided in the middle of the side.

[0017] Compared with the prior art, in a polishing fixture of the present utility model, by providing an overflow port on the fixture body, the polishing liquid can continuously and effectively flow through the surface of the product during the polishing process, ensuring that the abrasive in the polishing liquid is in full contact with the surface of the product and acts. This continuous flow not only improves the polishing efficiency but also accelerates the material removal rate on the surface of the product, that is, improves the thickness wear rate. Since the polishing liquid can be evenly distributed on the loading surface through the overflow port and continuously circulates during the polishing process, this helps to ensure that the polishing effect on each area of the product is basically the same. Therefore, the thickness of the product can be ground more evenly, avoiding the thickness deviation problem caused by uneven polishing, thereby improving the overall quality of the product. The yield rate of interference fringes is directly affected by the surface finish and thickness uniformity of the product. By increasing the fluidity of the polishing liquid and ensuring the thickness uniformity of the product, this polishing fixture can significantly improve the surface finish of the product, reduce the interference fringe problem caused by surface unevenness or thickness inconsistency, and thus improve the yield rate of interference fringes. The fixture body adopts a strip-shaped sheet structure, and the loading surface is a plane. This design makes the fixture more stable and reliable during operation, and also facilitates the loading and unloading of the product. In addition, the setting of the overflow port also simplifies the supply and discharge process of the polishing liquid, improving the operation convenience of the entire polishing process.

[0028] A polishing fixture provided by the present utility model has an overflow port provided on the fixture body, enabling the polishing liquid to continuously and effectively flow through the surface of the product during the polishing process, ensuring that the abrasive in the polishing liquid comes into full contact with the product surface and functions. This continuous flow not only improves the polishing efficiency but also accelerates the material removal rate on the product surface, that is, improves the thickness wear rate. Since the polishing liquid can be evenly distributed on the loading surface through the overflow port and continuously circulates during the polishing process, this helps to ensure that the polishing effect on each area of the product is basically the same.

In addition, the setting of the overflow port also simplifies the supply and discharge process of the polishing liquid, improving the operational convenience of the entire polishing process. Embodiment

[0029] An embodiment of the present utility model provides a polishing fixture, as Figures 1 to 3 shown, including a fixture body 10. The fixture body 10 has a strip-shaped sheet structure. The fixture body 10 includes a loading surface 110 for loading the product and an overflow port 120. The loading surface 110 is a plane and the area of the loading surface 110 is larger than the area of any adjacent surface of the loading surface 110. The overflow port 120 is located at the edge of the loading surface 110.

[0030] As Figure 1 and Figure 3As shown, more specifically, the cross-sectional shape of the fixture body 10 is rectangular. In this way, multiple fixture bodies 10 can be arranged more reasonably per unit area. The rectangular cross-sectional shape enables the fixture bodies 10 to be closely arranged in the planar layout, reducing space waste. Per unit area, multiple fixture bodies 10 can be arranged more reasonably, thereby improving the overall production efficiency of the polishing equipment. The rectangular fixture body 10 facilitates the standardized production of the fixture body 10. The fixtures on different batches or different equipment can maintain a high degree of consistency, enhancing the interchangeability of the fixtures. This not only simplifies the maintenance and replacement process of the fixtures but also reduces the production cost. The rectangular shape has good structural stability and can maintain the stability of the fixture body 10 during the polishing process, reducing problems such as fixture offset or deformation caused by vibration or external forces. This helps to ensure the stability of the polishing process and the reliability of the product quality. The rectangular fixture body 10 can adapt to glass products of various sizes. By adjusting the spacing between the fixtures or customizing fixtures of specific sizes, the polishing requirements of different products can be flexibly met. In addition, the rectangular design also facilitates the integration and cooperation with other polishing equipment or auxiliary tools.

[0031] As Figure 1 shown, more specifically, a fixing part 1110 is provided in the middle of the loading surface 110. The fixing part 1110 can be used to fix or place the product to be polished. The setting of the fixing part 1110 can firmly fix or place the product to be polished, effectively preventing the product from shifting or tilting due to factors such as vibration and liquid impact during the polishing process. This not only ensures the stability of the polishing process but also avoids the problem of uneven polishing that may occur due to the change in the product position. Since the product is stably fixed on the fixing part 1110, the polishing liquid can be more evenly distributed and act when flowing through the product surface, reducing the polishing error caused by the shaking of the product. This helps to improve the polishing accuracy and enables the product surface to achieve a higher smoothness and a more uniform thickness. The structure of the fixing part 1110 can be adjusted or customized according to the shape, size, and weight of different products to meet the polishing requirements of diverse products. This flexibility enables the fixture to be widely used in the polishing process of various glass products. The presence of the fixing part 1110 simplifies the loading and fixing process of the product. The operator only needs to place the product on the fixing part 1110 and make a slight adjustment to start polishing, without the need for additional fixing tools or steps. This not only improves the work efficiency but also reduces the operation difficulty and labor intensity. Since the product is stably fixed on the fixing part 1110, the impact and wear on the fixture body 10 caused by the shaking of the product are reduced. This helps to extend the service life of the fixture, reduce the replacement frequency, and lower the maintenance cost.

[0032] As Figure 1As shown, the fixture body 10 may include at least two overflow ports 120. More specifically, the two overflow ports 120 may be respectively provided at both ends of the fixture body 10.

[0033] It can be understood that one of the overflow ports 120 may be provided at one of the corners of the fixture body 10.

[0034] It can be understood that the other overflow port 120 may be provided on one of the sides of the fixture body 10. Specifically, the overflow port 120 is arc-shaped. More specifically, the overflow port 120 is provided in the middle of the side.

[0035] In this way, one end of the fixture is chamfered and the other end is cut with a semi-ellipse, allowing the polishing liquid to enter and exit from these two overflow ports 120, increasing the product thickness wear rate while making the product thickness more uniform, thereby improving the interference fringe yield.

[0036] By respectively providing the overflow ports 120 at both ends of the fixture body 10, the polishing liquid can enter from one end, flow through the entire loading surface 110 and then flow out from the other end, forming an effective circulating flow. This enhances the fluidity of the polishing liquid, enabling the abrasive in the polishing liquid to more fully contact and act on the product surface, thereby improving the polishing efficiency and product quality. One overflow port 120 is provided at the corner of the fixture body 10, while the other is provided in the middle of the side and presented in an arc shape. This layout ensures that the polishing liquid can be evenly distributed on the entire loading surface 110. Especially the arc-shaped design of the overflow port 120 enables the polishing liquid to form a smoother flow when flowing out, reducing the problem of uneven polishing caused by too fast flow rate or sudden change in direction. Therefore, the product thickness wear rate is increased, and at the same time the thickness is more uniform, thereby improving the interference fringe yield. The structure of chamfering one end and cutting a semi-ellipse at the other end of the fixture not only provides a channel for the entry and exit of the polishing liquid, but also cleverly optimizes the polishing area. The chamfering design helps to reduce the interference of the fixture on the polishing process and ensures that the polishing liquid can smoothly enter the loading surface 110; while the semi-ellipse cutting increases the diffusion area when the polishing liquid flows out, making the polishing effect more uniform. This fixture body 10 has strong compatibility and can adapt to the polishing requirements of products with different sizes and shapes. At the same time, by adjusting the position, quantity and shape of the overflow ports 120, the polishing effect can be further optimized to meet different process requirements. In addition, the flexibility of the fixture also enables it to better integrate and cooperate with other polishing equipment or auxiliary tools. Due to the reasonable design and clear layout of the overflow ports 120, it is more convenient and fast for the operator to add polishing liquid and clean the fixture. At the same time, this design also helps to reduce equipment failures and downtime caused by improper operation, improving production efficiency and equipment utilization rate.

[0037] Using such a polishing fixture can further reduce the defective rate. When using the polishing fixture before improvement for polishing operations, the input quantity was 2,880 pieces, and 284 pieces had interference fringes, with a defective rate of 9.86%. When using the improved polishing fixture for polishing operations, the input quantity was 3,984 pieces, and 14 pieces had interference fringes, with a defective rate of 0.351%. The yield of interference fringes increased from 90% to 99.6%, and the single-machine production capacity increased by 38%.

[0038] The technological steps of using a polishing fixture provided by an embodiment of the present utility model are as follows:

[0039] Step S1, cutting: Cut the polishing leather to a size suitable for the product;

[0040] Step S2, grooving: Open air grooves on the polishing leather, cut a corner at the upper left, and cut off a semi-ellipse on the right;

[0041] Step S3, installation: Glue it onto the bottom plate of the polishing machine with universal glue;

[0042] Step S4, production: The production time is adjusted from 510 seconds before the change to 330 seconds. The operator places the products regardless of the front or back position, and other parameters remain unchanged;

[0043] Step S5, inspection: Inspect the pass rate of interference fringes and the thickness difference of the products.

[0044] Compared with the prior art, for a polishing fixture provided by an embodiment of the present utility model, by providing an overflow port on the fixture body, the polishing liquid can continuously and effectively flow through the surface of the product during the polishing process, ensuring that the abrasive in the polishing liquid comes into full contact with the product surface and acts. This continuous flow not only improves the polishing efficiency but also accelerates the material removal rate on the product surface, that is, improves the thickness wear rate. Since the polishing liquid can be evenly distributed on the loading surface through the overflow port and continuously circulates during the polishing process, this helps to ensure that the polishing effect on each area of the product is basically the same. Therefore, the thickness of the product can be ground more evenly, avoiding the thickness deviation problem caused by uneven polishing, thereby improving the overall quality of the product. The yield of interference fringes is directly affected by the surface finish and thickness uniformity of the product. By increasing the fluidity of the polishing liquid and ensuring the thickness uniformity of the product, this polishing fixture can significantly improve the surface finish of the product, reduce the interference fringe problem caused by surface unevenness or thickness inconsistency, and thus improve the yield of interference fringes. The fixture body adopts a strip-shaped sheet structure, and the loading surface is a plane. This design makes the fixture more stable and reliable during operation, and also facilitates the loading and unloading of products. In addition, the setting of the overflow port also simplifies the supply and discharge process of the polishing liquid, improving the operation convenience of the entire polishing process.

[0045] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
