The following is combined with Figures 1 to 17 , a detailed description of the combined polishing fixture for different cross-sections of the product is given.

[0060] In some embodiments, a combined polishing fixture 100 for different cross-sections of a product is as follows: Figure 1 As shown, it includes a fixture body 190, a first profiling side thrust block 110, a second profiling side thrust block 120 and an insert 160; Figure 2 The clamp body 190 is provided with a receiving cavity 141, and the first profiling side thrust block 110, the second profiling side thrust block 120 and the insert 160 are all disposed in the receiving cavity 141; Figure 3The first profiling side push block 110, the second profiling side push block 120 and the insert 160 are respectively connected to the clamp body 190, and the connection distance between the first profiling side push block 110 and the second profiling side push block 120 and the clamp body 190 can be adjusted to adjust the positions of the first profiling side push block 110 and the second profiling side push block 120 in the accommodating cavity 141 respectively, so that the clamp body 190, the first profiling side push block 1 10. The second profiling side push block 120 and the insert 160 jointly form a clamping area in the accommodating cavity 141; wherein the first profiling side push block 110, the clamp body 190 and the insert 160 jointly form a first clamping area 101, and the second profiling side push block 120, the clamp body 190 and the insert 160 jointly form a second clamping area 102; that is, the clamping area includes the first clamping area 101 and the second clamping area 102. Exemplarily, in this embodiment, the first clamping area 101 and the second clamping area 102 are adjacent. Figure 3 In the embodiment, the clamping area also includes a third clamping area 103 and a fourth clamping area 104 which will be described below, see the relevant embodiments of this article for details. With such a design, through the cooperation of the fixture body 190, the first profiling side push block 110, the second profiling side push block 120 and the insert 160, on the one hand, the connection distance between the first profiling side push block 110 and the second profiling side push block 120 and the fixture body 190 can be adjusted, thereby improving the adaptability of the combined polishing fixture 100 with different cross-sections of the product to the product to be polished, so that the combined polishing fixture 100 with different cross-sections of the product can process products to be polished of different specifications; on the other hand, different first profiling side push blocks 110 and second profiling side push blocks 120 are used, which can be applied to the processing of products to be polished of different shapes; on the other hand, the clamping area has a first The clamping area 101 and the second clamping area 102, so that different cross-sections of two specifications of products to be polished, such as adjacent cross-sections, can be processed simultaneously, which greatly improves the processing efficiency of the polishing process; on the other hand, the combined polishing fixture 100 for different cross-sections of the product is a leveling fixture made with the product contour as the base point, so that it can ensure that the flatness of the polishing surface of the two specifications of the products to be polished tends to be consistent, so the two specifications of the products to be polished can be clamped together for polishing, which is not only suitable for the combined polishing of different cross-sections of glass products, but also suitable for the combined polishing of different cross-sections of products such as metal products, plastic products, ceramic products, stone products and wood products.

[0061] In order to facilitate carrying the combined polishing fixture 100 of different cross-sections of the product, in some embodiments, such as Figure 1 and Figure 2As shown, the combined polishing fixture 100 for different product sections further includes a fixture handle 191 disposed on the fixture body 190, or the combined polishing fixture 100 for different product sections further includes a fixture handle 191, and the fixture handle 191 is disposed on a fixture outer body 140 of the fixture body 190 to be described below. Such a structural design is conducive to conveniently carrying, transferring and placing the combined polishing fixture 100 for different product sections.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the fixture body 190 includes a fixture outer body 140 and a compensation base plate 150, wherein the fixture outer body 140 is connected to the compensation base plate 150 to form the accommodating cavity 141; the insert 160 is connected to the compensation base plate 150 and is disposed on the compensation base plate 150; the first profiling side thrust block 110 and the second profiling side thrust block 120 are respectively connected to the fixture outer body 140. Exemplarily, the shape of the compensation base plate 150 is set according to the specifications and shape of the product to be polished. When necessary, the compensation base plate 150 can be replaced to adapt to more products to be polished with different specifications or shapes, so as to improve the versatility of the combined polishing fixture 100 with different cross-sections of the product.

[0063] For example, Figure 4 and Figure 5 As shown, the fixture outer shell 140 has a quadrilateral shape. For example, the fixture outer shell 140 has an axisymmetric cross-sectional shape. As an example, the fixture outer shell 140 has a rectangular or rounded rectangular cross-sectional shape. As an example, Figure 5 In the embodiment shown, the outer housing 140 of the fixture has an isosceles trapezoidal shape; Fig.13 and Fig.17 The first profiling side push block 110 and the third profiling side push block 130 are symmetrical in shape. In this way, under the premise of meeting the shape requirements of the product to be polished, the preparation of the first profiling side push block 110 and the third profiling side push block 130 can be reduced, the cost of some molds can be saved, and the collection and storage of workpieces are relatively simpler.

[0064] As an example, Figure 5 As shown, the waistline angle of the isosceles trapezoid is 21 degrees. Figure 6 As shown, the fixture outer shell 140 has a slight curvature; Figure 6In the embodiment shown, it is 4 degrees. In other embodiments, the curvature can be set or adjusted according to the actual shape of the workpiece to be polished in the polishing process to cooperate with the avoidance effect of the arc slope 167 of the insert 160, which is beneficial to the movement of the polished workpiece according to the designed path. Therefore, two specifications of products to be polished can be clamped together for polishing at the same time, and the flatness of the polishing surfaces of the two specifications of products to be polished can be ensured to be consistent.

[0065] In some embodiments, such as Figure 7 and Figure 8 As shown, the compensation base plate 150 is provided with a first positioning structure 151 and a first mounting hole 152; Fig. 9 and Fig.10 As shown, the insert 160 is provided with a second positioning structure 165 corresponding to the first positioning structure 151, and a second mounting hole 166 corresponding to the first mounting hole 152; the insert 160 is positioned with the compensation base plate 150 through the first positioning structure 151 and the second positioning structure 165; the insert 160 is fixedly connected with the compensation base plate 150 through the first mounting hole 152 and the second mounting hole 166. As an example, the first positioning structure 151 and the second positioning structure 165 are both positioning holes, and the combined polishing fixture 100 for different cross-sections of the product adopts positioning pins to be inserted into the first positioning structure 151 and the second positioning structure 165, so that the insert 160 and the compensation base plate 150 are positioned. As an example, the first mounting hole 152 and the second mounting hole 166 are both screw holes, and the combined polishing fixture 100 for different cross-sections of the product is screwed to the first mounting hole 152 and the second mounting hole 166 by fixing screws, so that the insert 160 is fixedly connected to the compensation base plate 150. Such a design greatly improves the accuracy of the insert 160 being set on the compensation base plate 150, and also improves the stability of the insert 160 being set on the compensation base plate 150, thereby ensuring as much as possible the yield rate of the combined polishing fixture 100 for different cross-sections of the product clamping two specifications of the products to be polished together for polishing.

[0066] In some embodiments, such as Fig.13 As shown, the first contoured side thrust block 110 is provided with a first contoured outer side surface 111. Fig.15 As shown, the second contoured side thrust block 120 is provided with a second contoured outer side surface 121; Fig. 9 and Fig.10As shown, the insert 160 is provided with a first contoured inner side surface 161 corresponding to the first contoured outer side surface 111, and is provided with a second contoured inner side surface 162 corresponding to the second contoured outer side surface 121. For example, in this embodiment, the first contoured inner side surface 161 and the second contoured inner side surface 162 are adjacent to each other; in other embodiments, the first contoured inner side surface 161 and the second contoured inner side surface 162 may also be spaced apart or adjacent to each other through other shapes. Figure 3 The first profiling outer side surface 111 and the first profiling inner side surface 161 together form the first clamping area 101 in the accommodating cavity 141; the second profiling outer side surface 121 and the second profiling inner side surface 162 together form the second clamping area 102 in the accommodating cavity 141. Such a design is conducive to ensuring the clamping stability of the product to be polished as much as possible, thereby ensuring the clamping polishing effect and the product yield rate as much as possible; on the other hand, it is conducive to processing different cross-sections of two specifications of products to be polished, such as adjacent cross-sections, at the same time, thereby improving the processing efficiency of the polishing process.

[0067] In some embodiments, in combination Fig.13 and Fig.14 , the first contoured thrust block 110 has a slight arc; Fig.14 The curvature is shown as 4 degrees. In other embodiments, the curvature can be set or adjusted according to the actual shape of the product to be polished. Fig.15 and Fig.16 , the second contoured thrust block 120 also has a slight curvature; Fig.16 The curvature is shown as 2 degrees. In other embodiments, the curvature can be set or adjusted according to the actual shape of the product to be polished. Such a structural design, through the cooperation of the fixture body 190, the first profiling side push block 110, the second profiling side push block 120 and the insert 160, is conducive to the movement of the polishing workpiece according to the designed path, so as to facilitate the simultaneous processing of different cross-sections of two specifications of products to be polished. Two specifications of products to be polished can be clamped together for polishing; different cross-sections of a product to be polished can also be processed simultaneously.

[0068] In some embodiments, in combination Figure 1 and Figure 2The combined polishing fixture 100 for different cross-sections of the product further includes a third profiling side push block 130 disposed in the accommodating cavity 141; the third profiling side push block 130 is connected to the fixture body 190, and the connection distance can be adjusted to adjust the position of the third profiling side push block 130 in the accommodating cavity 141, so that the fixture body 190, the first profiling side push block 110, the second profiling side push block 120, the third profiling side push block 130 and the insert 160 together form the clamping area in the accommodating cavity 141; combined Figure 3 , and the third contoured side push block 130, the fixture body 190 and the insert 160 together form a third clamping area 103. For example, the third clamping area 103 is adjacent to the second clamping area 102. Such a design, in conjunction with the corresponding polishing process used to grind and polish the workpiece, can simultaneously process three different sections, the three different sections include but are not limited to three adjacent sections, the three different sections can belong to the same product to be polished, or to two products to be polished of the same or different specifications, thereby greatly improving the processing efficiency of the polishing process, and this design concept is a leveling fixture made based on the product contour, so as to ensure that the flatness of the polishing surface at each grinding and polishing position tends to be consistent as much as possible, so that two specifications of products to be polished can be clamped together for polishing.

[0069] In some embodiments, such as Fig.17 As shown, the third profiling side thrust block 130 is provided with a third profiling outer side surface 131; Fig. 9 and Fig.10 The insert 160 is provided with a third profiling inner side surface 163 corresponding to the third profiling outer side surface 131. Exemplarily, in this embodiment, the third profiling inner side surface 163 is adjacent to the second profiling inner side surface 162; Figure 3 , the third contoured outer side surface 131 and the third contoured inner side surface 163 jointly form the third clamping area 103. Such a structural design, on the one hand, is conducive to processing adjacent sections of three specifications of products to be polished at the same time, thereby improving the processing efficiency of the polishing process. In contrast, the traditional clamping and polishing process is to clamp a product and polish and grind one surface of the product. This is caused by different ideas of the processing process. Therefore, it is impossible to process different sections of two specifications of products to be polished, such as adjacent sections, at the same time, and it is even more difficult to process adjacent sections of three specifications of products to be polished at the same time; on the other hand, it is conducive to ensuring the clamping stability of the products to be polished as much as possible, thereby ensuring the clamping and polishing effect and the product yield as much as possible, which is conducive to promotion and application.

[0070] In some embodiments, in combination Figure 3 and Fig. 9 The insert 160 is provided with a fourth contoured inner side surface 164 , and the insert 160 and the clamp body 190 together form a fourth clamping area 104 at the fourth contoured inner side surface 164 . For other embodiments in which the fourth profiling inner side surface 164 and the fourth clamping area 104 are not provided, the product to be polished can be directly fixed, for example, against it; however, as the polishing requirements are becoming more and more personalized, some products need to have more polishing positions, and there is also a demand for improving efficiency. Therefore, by designing the matching fourth profiling inner side surface 164 and the fourth clamping area 104, the combined polishing fixture 100 for different cross-sections of the product can process products to be polished of more specifications, and inserts 160 of different shapes and specifications can be optionally used when in use. Through the design of the first profiling inner side surface 161, the second profiling inner side surface 162, the third profiling inner side surface 163 and the fourth profiling inner side surface 164 and other structures, the combined polishing fixture 100 for different cross-sections of the product can be applicable to products to be polished of various specifications and shapes, and different cross-sections of products to be polished of various specifications and shapes can be processed simultaneously, thereby greatly improving the processing efficiency of the polishing process; and under the premise of improving the processing efficiency of the polishing process, due to stable clamping, the yield of the product can be guaranteed as much as possible.

[0071] In some embodiments, such as Fig. 9 and Fig.10 As shown, the insert 160 is provided with a first contoured inner side surface 161, a second contoured inner side surface 162, a third contoured inner side surface 163 and a fourth contoured inner side surface 164, and the insert 160 is also provided with a second positioning structure 165 and a second mounting hole 166. Fig.11 , the insert 160 is further provided with an arc-shaped inclined surface 167. In some embodiments, in combination with Fig.12 , the insert 160 has a slight curvature; Fig.12 The curvature is shown as 4 degrees. In other embodiments, the curvature can be set or adjusted according to the actual shape of the product to be polished. The embodiments of the present application do not impose additional restrictions on this. The other embodiments are similar and will not be described in detail here. Fig.12 The arc-shaped inclined surface 167 is an inclined surface as a whole, and the surface is arc-shaped, so that the insert 160 cooperates with the first profiling side push block 110, the second profiling side push block 120 and the third profiling side push block 130, and is suitable for glass products with a certain curvature; and when the adjacent sections of two specifications of the products to be polished are polished at the same time, due to the avoidance effect of the arc-shaped inclined surface 167, it is beneficial to move the polished workpiece according to the designed path, so that the two specifications of the products to be polished can be clamped together for polishing at the same time, and it can be ensured that the flatness of the polished surfaces of the two specifications of the products to be polished tends to be consistent.

[0072] In order to accurately adjust the connection distance between the first profiling side push block 110 and the second profiling side push block 120 and the fixture body 190, in some embodiments, the combined polishing fixture 100 for different cross-sections of the product also includes side push screws; the first profiling side push block 110 and the second profiling side push block 120 are respectively screwed to the fixture body 190 through the side push screws, and the connection distance between the first profiling side push block 110 and the second profiling side push block 120 and the fixture body 190 are adjusted through the side push screws, that is, the connection distance between the first profiling side push block 110 and the fixture body 190 is adjusted through one group of the side push screws, and the connection distance between the second profiling side push block 120 and the fixture body 190 is adjusted through another group of the side push screws; each group of the side push screws includes at least one side push screw. That is, the first profiling side push block 110 is screwed and fixed to the fixture body 190 through the side push screw, and as the screwing depth changes, the connection distance, i.e., the relative distance, between the first profiling side push block 110 and the fixture body 190 changes, thereby adjusting the first clamping area 101; similarly, the second profiling side push block 120 is screwed and fixed to the fixture body 190 through the side push screw, and as the screwing depth changes, the connection distance, i.e., the relative distance, between the second profiling side push block 120 and the fixture body 190 changes, thereby adjusting the second clamping area 102. Such a structural design further improves the adaptability of the combined polishing fixture 100 for different cross-sections of the product to the product to be polished, so that the combined polishing fixture 100 for different cross-sections of the product can process products to be polished of different specifications.

[0073] In some embodiments, such as Figure 1 and Figure 2As shown, the side thrust screw includes an orthogonal side thrust screw 170 and an anti-thread side thrust screw 180; the first profiling side thrust block 110 is screwed to the fixture body 190 through the orthogonal side thrust screw 170 and the anti-thread side thrust screw 180 respectively; the second profiling side thrust block 120 is screwed to the fixture body 190 through the orthogonal side thrust screw 170 and the anti-thread side thrust screw 180 respectively; that is, there are two groups of the side thrust screws, each group of the side thrust screws includes an orthogonal side thrust screw 170 and an anti-thread side thrust screw 180, the first profiling side thrust block 110 is screwed to the fixture body 190 through the first group of the side thrust screws; the second profiling side thrust block 120 is screwed to the fixture body 190 through the second group of the side thrust screws. For example, such a design, on the one hand, is conducive to adjusting the connection distance of the first contoured side push block 110, and adjusting the connection distance between the second contoured side push block 120 and the fixture body 190, thereby improving the adaptability of the combined polishing fixture 100 with different cross-sections of the product to the product to be polished, so that the combined polishing fixture 100 with different cross-sections of the product can process products to be polished of different specifications; on the other hand, through the cooperation of the positive side push screw 170 and the negative side push screw 180, the clamping stability of the product to be polished in the grinding and polishing processing environment is guaranteed as much as possible. In contrast, the conventional process only polishes one side of a product to be polished, and thus the product to be polished can be clamped and fixed on multiple sides or at different positions of multiple sides of the product to be polished. Therefore, there is no need to additionally adopt the matching design of the orthogonal side thrust screw 170 and the anti-thread side thrust screw 180. The embodiments of the present application are dedicated to simultaneously processing different cross-sections of two or more specifications of products to be polished, so the fixed surfaces and positions are limited, and thus it is necessary to adopt the matching design of the orthogonal side thrust screw 170 and the anti-thread side thrust screw 180 to improve the stability of clamping and fixing the products to be polished while ensuring that the flatness of the polishing surfaces of the two specifications of the products to be polished tends to be consistent.

[0074] In some embodiments, the compensation base plate 150 is designed with a screw hole connected to the insert 160 and the fixture outer body 140 as the first mounting hole 152 to ensure the basic outline of the combined polishing fixture 100 with different cross-sections of the product and the shape of the accommodating cavity 141. The two specifications of the products to be polished are placed in the corresponding clamping area, i.e., the cavity, according to the outline of the insert 160. The first profiling side push block 110 and the second profiling side push block 120 are used to bring the products to be polished, the insert 160, the fixture outer body 140, and / or the compensation base plate 150 closer. Then, the first profiling side push block 110 and the second profiling side push block 120 are locked respectively with the positive side push screw 170 and the negative side push screw 180, so that the two specifications of the products to be polished are at the same level and will not shake during the polishing process. In this way, the leveling fixture can be made with the product outline as the base point, thereby ensuring that the flatness of the polishing surface of the two specifications of the products tends to be consistent, so that the two different specifications of the products can be clamped together for polishing.

[0075] For the embodiment with the third profiling side thrust block 130, exemplarily, the third profiling side thrust block 130 is also screwed with the fixture body 190 through the orthogonal side thrust screw 170 and the anti-thread side thrust screw 180; that is, the combined polishing fixture 100 for different cross-sections of the product has three groups of the side thrust screws, and the third profiling side thrust block 130 is screwed with the fixture body 190 through the third group of the side thrust screws. Exemplarily, the orthogonal side thrust screws 170 and the anti-thread side thrust screws 180 are arranged in a preset order, for example, in a clockwise or counterclockwise order. Such a design, through the cooperation of the positive thread side thrust screw 170 and the negative thread side thrust screw 180, is conducive to adjusting the connection distance between the first profiling side thrust block 110 and the second profiling side thrust block 120 and the fixture body 190. For the embodiment with the third profiling side thrust block 130, it is also conducive to adjusting the connection distance between the third profiling side thrust block 130 and the fixture body 190, thereby improving the adaptability of the combined polishing fixture 100 of the product with different cross-sections to the product to be polished, so that the combined polishing fixture 100 of the product with different cross-sections can process different specifications. on the other hand, it is conducive to ensuring the fixing effect of products to be polished of different specifications and / or different shapes as much as possible, and avoids the process errors and / or product defects caused by the loosening or simultaneous removal of the positive side thrust screw 170 and the negative side thrust screw 180 due to the vibration environment or misoperation, thereby greatly enhancing the prevention of misoperation and prevention of clamping looseness of the combined polishing fixture 100 with different cross-sections of the product, while improving the processing efficiency of the polishing process, greatly reducing product defects and greatly reducing the safety risks of production.
