[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] like Figures 1-3 As shown, this embodiment provides a polishing fixture for the sealing surface of the water channel of a target backplate, including a fixture body and a drive member (not shown in the figure), the drive member being configured to drive the fixture body to rotate.

[0039] The fixture body includes a central rotating shaft 1, a polishing pressure component 2, and a grinding head (not shown in the figure).

[0040] The central shaft 1 can be connected to the output end of the drive component, which can drive the central shaft 1 to rotate around its own axis. The polishing pressure component 2 is sleeved and connected to the outer periphery of the central shaft 1, and the central axis of the polishing pressure component 2 is collinear with the central axis of the central shaft 1. The rotation of the central shaft 1 can drive the polishing pressure component 2 to rotate together. The grinding head is sleeved on the outer periphery of the central shaft 1, and the central axis of the grinding head is collinear with the central axis of the central shaft 1. Along the length direction of the central shaft 1, the grinding head is connected to the surface of the polishing pressure component 2 opposite to the drive component. The grinding head can abut against the sealing surface 110 of the water channel 100 so that the grinding head rubs against the sealing surface 110 when it rotates together with the polishing pressure component 2.

[0041] In practice, the assembled fixture body is connected to the drive unit, and the position of the fixture body is adjusted so that the grinding head abuts against the sealing surface 110 of the water inlet 100. Then the drive unit is started so that the fixture body begins to rotate, thereby polishing the sealing surface 110 by friction of the grinding head.

[0042] The polishing fixture for the sealing surface of the water channel opening of the target material backplate provided in this embodiment, by setting the polishing pressure component 2, can not only fix the grinding head, but also uniformly transmit pressure to the grinding head during the polishing process, avoiding the problem of uneven polishing texture on the sealing surface 110 due to uneven pressure. In addition, both the polishing pressure component 2 and the grinding head share the same central axis with the central rotating shaft 1, so that the grinding head can maintain a stable motion trajectory during rotation, reducing yaw phenomenon, thereby further improving the uniformity of polishing and reducing the risk of scratching the sealing surface 110.

[0043] like Figures 1-3As shown, in some embodiments, the fixture body further includes an insert block 3. One end of the central rotating shaft 1 is configured to pass through the central hole of the insert block 3. The central rotating shaft 1 and the central hole of the insert block 3 are in clearance fit, and the central rotating shaft 1 can rotate relative to the central hole of the insert block 3. Along the length direction of the central rotating shaft 1, the grinding head is disposed between the polishing pressure member 2 and the insert block 3. The insert block 3 is configured to be embedded in the groove 120 of the water channel 100. When the insert block 3 is embedded in the groove 120, the grinding head abuts against the sealing surface 110 and the grinding head covers the sealing surface 110.

[0044] With this setting, the insert block 3 can precisely limit the fixture body. That is, by inserting the insert block 3 into the groove 120 and extending the central rotating shaft 1 into the central hole of the insert block 3, the central rotating shaft 1 can be prevented from shifting radially, thereby preventing the grinding head from shifting radially during the polishing process. At the same time, it ensures that the grinding head always covers the sealing surface 110, which can effectively achieve uniform polishing of the sealing surface 110 and further improve the polishing quality.

[0045] like Figure 3 The diagram shown is a structural schematic of the waterway 100. The detailed structure, connection relationship and function of the waterway 100 are mature existing technologies in this field, and will not be described in detail in this application.

[0046] In some embodiments, a rotary bearing is provided in the central hole of the insert block 3, and one end of the central rotating shaft 1 extending into the central hole of the insert block 3 is connected to the rotary bearing. The rotary bearing facilitates smoother and more stable rotation of the central rotating shaft 1.

[0047] In some embodiments, the dimension of the embedded block 3 along the length direction of the central axis 1 is equal to the groove depth of the groove 120. That is, the exposed surface of the embedded block 3 after being embedded in the groove 120 can be flush with the sealing surface 110 around the groove 120. For example, after the embedded block 3 is embedded into the groove 120 from top to bottom, the upper surface of the embedded block 3 is flush with the sealing surface 110.

[0048] This configuration ensures that the embedded block 3 forms a stable reference surface with the sealing surface 110 during polishing, guaranteeing a uniform distribution of the force exerted by the grinding head on the sealing surface 110 and preventing uneven polishing or localized over-polishing due to height differences. Furthermore, the embedded block 3 also provides a dimensional reference during machining, facilitating precise control of machining dimensions.

[0049] like Figure 1 and Figure 2As shown, in some embodiments, the polishing pressure member 2 includes a first sleeve 21 and a second sleeve 22 connected to each other. The central axis of the first sleeve 21 and the central axis of the second sleeve 22 are both collinear with the central axis of the central rotating shaft 1. The radial dimension of the second sleeve 22 is larger than the radial dimension of the first sleeve 21. Along the length direction of the central rotating shaft 1, the driving member can abut against the end face of the first sleeve 21 away from the second sleeve 22, and the grinding head is connected to the end face of the second sleeve 22 away from the first sleeve 21.

[0050] With this configuration, the drive component abuts against the first sleeve 21, enabling stable transmission of the drive torque. Meanwhile, the larger radial dimension of the second sleeve 22 provides a larger support area, thereby reducing the radial sway of the fixture body during rotation and improving the stability of polishing.

[0051] Preferably, such as Figure 1 As shown, both the first sleeve 21 and the second sleeve 22 are cylinders with inner holes. The projection shape of the grinding head along the length of the central axis 1 is circular, and the diameter of the grinding head is not less than the diameter of the second sleeve 22. The cylindrical structure is relatively simple to process, which facilitates precise control of dimensions and coaxiality. At the same time, the diameter of the grinding head is not less than the diameter of the second sleeve 22, so that the grinding head can fully cover the sealing surface 110 during polishing.

[0052] In some embodiments, the first sleeve 21 and the second sleeve 22 are integrally formed. This integral forming facilitates the processing and manufacturing of the polishing pressure member 2.

[0053] In some embodiments, the grinding head is configured as a scouring pad grinding head. Compared to a rigid grinding head, the scouring pad material is flexible and has moderate abrasive power, which can remove small protrusions on the surface of the sealing surface 110 while avoiding deep scratches on the sealing surface 110, thereby improving the polishing quality.

[0054] In some embodiments, the drive element is a pistol drill. During use, the user can hold the pistol drill to perform polishing operations. This design makes the polishing process more flexible and convenient.

[0055] In some embodiments, the central rotating shaft 1, the polishing pressure member 2, and the insert block 3 are all made of metal. Metal materials have high rigidity and wear resistance, ensuring that the fixture body is not easily deformed or worn during long-term use. For example, the metal material can be stainless steel, aluminum alloy, copper alloy, etc.

[0056] Of course, in other embodiments, the central rotating shaft 1, the polishing pressure component 2, and the insert block 3 can all be made of non-metallic materials (such as plastics, ceramics, etc.) or composite materials (such as carbon fiber composites, glass fiber reinforced plastics, etc.). Non-metallic and composite materials are generally lighter than metallic materials, which helps to reduce the weight of the entire fixture body, making it easier to operate and move, especially when operated by hand, thus reducing operator fatigue.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
