[0037] like Figure 1 and Figure 2 As shown, the product requiring polishing has a body 101 and a hanging ear. The hanging ear includes a first ear portion 102 and a second ear portion 103. Exemplarily, in this embodiment, the first ear portion 102 and the second ear portion 103 are respectively disposed on both sides of the body 101. The body 101 adopts an irregular curved surface design. The first ear portion 102 and the second ear portion 103 are respectively provided with a first insertion portion 1021 and a second insertion portion 1031. Exemplarily, in this embodiment, the first insertion portion 1021 and the second insertion portion 1031 are respectively a first through hole and a second through hole.

[0038] To prevent the products mentioned above from shifting during polishing, please refer to [link / reference needed]. Figures 3 to 9 and combined Figure 1 and Figure 2 This embodiment provides a product polishing fixture, which includes a mounting base 1 and a positioning mechanism. The top of the mounting base 1 is used to mount the body 101, and the first ear 102 and the second ear 103 are fastened to the side wall of the mounting base 1 in different directions. Based on the above description, the first ear 102 and the second ear 103 are respectively disposed on both sides of the body 101. Thus, in this embodiment, when the body 101 is mounted on the mounting base 1, the first ear 102 and the second ear 103 are respectively fastened to both sides of the mounting base 1 along the first horizontal direction.

[0039] The positioning mechanism includes a push rod 21 and a drive module 22. The drive module 22 is configured to drive the push rod 21 to move so that the push rod 21 is inserted into the first insertion part 1021 and the second insertion part 1031 from the inside of the product. Specifically, in this embodiment, the drive module 22 is configured to drive the push rod 21 to move so that the push rod 21 is inserted into the first through hole and the second through hole from the inside of the product.

[0040] It is understood that the first insertion part 1021 may also be a groove or protrusion structure formed by bending the irregular curved surface inside the first ear 102. Correspondingly, the end of the push rod 21 used to insert into the first insertion part 1021 is provided with a contour structure for inserting into the groove or accommodating the protrusion. Similarly, the second insertion part 1031 may also be a groove or protrusion structure formed by bending the irregular curved surface inside the second ear 103. The end of the push rod 21 used to insert into the second insertion part 1031 is provided with a contour structure for inserting into the groove or accommodating the protrusion. This embodiment does not impose specific limitations on this.

[0041] Based on the above, the mounting base 1 is used to hold the product, and the mounting base 1 can restrict the product from moving downward in the vertical direction. The product polishing fixture is connected to the first insertion part 1021 and the second insertion part 1031 by the push rod 21. The cooperation between the push rod 21 and the mounting base 1 can jointly restrict the product from moving horizontally. Moreover, the push rod 21 can restrict the product from moving upward in the vertical direction.

[0042] Specifically, in this embodiment, the mounting base 1 can restrict the product from moving upward in the vertical direction and in the first horizontal direction, while the push rod 21 can restrict the product from moving in the second horizontal direction perpendicular to the first direction and restrict the product from moving upward in the vertical direction.

[0043] As described above, this embodiment uses the cooperation of the mounting base 1 and the push rod 21 to limit the product's displacement in both the vertical and horizontal directions. The mounting base 1 limits the product's position from the inside, and the push rod 21 is inserted into the first insertion part 1021 and the second insertion part 1031 from the inside of the product. Therefore, the push rod 21 is not exposed on the outside of the product, thus avoiding interference with the polishing machine's polishing of the product's outer surface. This ensures that all parts of the product's outer surface are fully polished, thereby guaranteeing that the product's appearance quality and dimensional accuracy meet the requirements after polishing.

[0044] It is worth noting that in other optional embodiments, the first ear 102 and the second ear 103 may also be arranged at an angle. That is, in other optional embodiments, the first ear 102 and the second ear 103 may also be attached to the side wall of the carrier 1 in two directions arranged at an angle. This embodiment does not impose specific limitations on this.

[0045] Based on the above description, in this embodiment, the top rod 21 includes a first rod portion 211 and a second rod portion 212. The drive module 22 can drive the first rod portion 211 and the second rod portion 212 to respectively insert into the first insertion portion 1021 and the second insertion portion 1031. The first rod portion 211 and the second rod portion 212 operate synchronously, that is, the insertion of the first rod portion 211 into the first insertion portion 1021 and the insertion of the second rod portion 212 into the second insertion portion 1031 are completed synchronously, thereby ensuring that the product can be accurately positioned.

[0046] For example, in this embodiment, the drive module 22 includes a sliding seat 221 and a drive member 222. The sliding seat 221 is provided with a first inclined surface 2211 and a second inclined surface 2212. Based on the above description, the first inclined surface 2211 and the second inclined surface 2212 are provided on both sides of the sliding seat 221 along the first horizontal direction. The first rod portion 211 is provided with a third inclined surface 2111, which is adapted to and fits against the first inclined surface 2211. The second rod portion 212 is provided with a fourth inclined surface 2121, which is adapted to and fits against the second inclined surface 2212. The drive member 222 is configured to drive the sliding seat 221 to move in the vertical direction. The sliding seat 221 can drive the first rod portion 211 to move away from the sliding seat 221 through the first inclined surface 2211, and drive the second rod portion 212 to move away from the sliding seat 221 through the second inclined surface 2212.

[0047] It is understood that the drive component 222 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and this embodiment does not impose specific restrictions on it.

[0048] Therefore, in this embodiment, the sliding seat 221 is disposed between the first rod portion 211 and the second rod portion 212, and both the first rod portion 211 and the second rod portion 212 extend along the first horizontal direction and are connected to the sliding seat 221 through a wedge structure. Thus, when the sliding seat 221 moves in the vertical direction, the first rod portion 211 and the second rod portion 212 can move in opposite directions along the first horizontal direction, and then be inserted into the first through hole and the second through hole respectively.

[0049] It is understood that in other alternative embodiments, the first rod 211 and / or the second rod 212 may also be connected to the sliding seat 221 via a worm gear or rack and pinion mechanism, and this embodiment does not impose specific limitations on this.

[0050] Moreover, it is worth noting that the positions of the first inclined surface 2211 and the second inclined surface 2212 on the sliding seat 221 can be specifically set according to the actual positions of the first ear 102 and the second ear 103 on the body 101. This embodiment does not impose specific restrictions on this.

[0051] It is also worth noting that the size and shape of the cross-section of the first rod portion 211 can be specifically set according to the size and shape of the cross-section of the first perforation, and the size and shape of the cross-section of the second rod portion 212 can be specifically set according to the size and shape of the cross-section of the second perforation. This embodiment does not impose specific limitations on this.

[0052] Furthermore, in this embodiment, the placement seat 1 is provided with a cavity 11, and the sliding seat 221 is disposed in the cavity 11. The placement seat 1 is provided with a first through hole 12 and a second through hole 13, both of which are connected to the cavity 11. Based on the above, in this embodiment, both the first through hole 12 and the second through hole 13 extend along a first horizontal direction. The first rod portion 211 is inserted into the first through hole 12 and can extend out of the first through hole 12 to insert into the first insertion portion 1021. The second rod portion 212 is inserted into the second through hole 13 and can extend out of the second through hole 13 to insert into the second insertion portion 1031. The placement seat 1 guides the movement of the first rod portion 211 through the first through hole 12 and guides the movement of the second rod portion 212 through the second through hole 13, thereby ensuring that the first rod portion 211 can be accurately inserted into the first through hole and that the second rod portion 212 can be accurately inserted into the second through hole.

[0053] Furthermore, in this embodiment, the sliding seat 221 is provided with a first sliding groove 2213 and a second sliding groove 2214. The bottom of the first sliding groove 2213 forms a first inclined surface 2211, and the bottom of the second sliding groove 2214 forms a second inclined surface 2212. The first sliding groove 2213 and the second sliding groove 2214 can further provide a guiding function and limit the first rod portion 211 and the second rod portion 212, thereby further ensuring that the first rod portion 211 can be accurately inserted into the first through hole and the second rod portion 212 can be accurately inserted into the second through hole.

[0054] In addition, a first spring 2112 is sleeved on the outer periphery of the first rod portion 211. One end of the first spring 2112 abuts against the cavity wall of the cavity 11, and the other end of the first spring 2112 is connected to the end of the first rod portion 211 where the third inclined surface 2111 is provided, so that when the sliding seat 221 is reset in the vertical direction, the first rod portion 211 can be driven to reset.

[0055] Specifically, when the sliding seat 221 moves vertically to drive the first rod 211 to insert into the first through hole, the first spring 2112 is compressed and deformed. When the sliding seat 221 returns to its original position in the vertical direction, the first spring 2112 recovers its deformation, thereby driving the first rod 211 to return to its original position so that the first rod 211 exits the first through hole, thereby releasing the first rod 211 from the first insertion part 1021.

[0056] Correspondingly, a second spring 2122 is sleeved on the outer periphery of the second rod 212. One end of the second spring 2122 abuts against the cavity wall of the cavity 11, and the other end of the second spring 2122 is connected to the end of the second rod 212 where the fourth inclined surface 2121 is provided, so that when the sliding seat 221 is reset in the vertical direction, the second rod 212 can be driven to reset.

[0057] Specifically, when the sliding seat 221 moves vertically to drive the second rod 212 to insert into the second through hole, the second spring 2122 is compressed and deformed. When the sliding seat 221 returns to its original position in the vertical direction, the second spring 2122 recovers its deformation, thereby driving the second rod 212 to return to its original position so that the second rod 212 exits the second through hole, thereby releasing the insertion of the second rod 212 into the second insertion part 1031.

[0058] As described above, in this embodiment, the first spring 2112 automatically releases the connection between the first rod 211 and the first insertion part 1021, and the second spring 2122 automatically releases the connection between the second rod 212 and the second insertion part 1031, thereby making it convenient to remove the product from the carrier 1 after the polishing operation is completed.

[0059] Furthermore, in this embodiment, the top surface of the mounting base 1 is formed as a contoured surface 14, which is contoured to the bottom surface of the body 101, thereby ensuring that the body 101 can be tightly mounted on the top of the mounting base 1, thereby further positioning the product and more effectively preventing the product from shaking during the polishing process.

[0060] It is understood that the shape of the contour surface 14 is specifically set according to the actual shape of the body 101, and this embodiment does not impose specific restrictions on it.

[0061] In addition, a contour wall 15 is provided on one side of the top of the mounting base 1, and one side of the body 101 is in contact with the contour wall 15, thereby providing positioning for placing the product on the mounting base 1, and thus ensuring that the product can be accurately placed in the corresponding position of the mounting base 1.

[0062] For example, in this embodiment, the contour wall 15 is disposed on one side of the top of the mounting base 1 along the second horizontal direction, thereby assisting in limiting the product in the second horizontal direction.

[0063] Furthermore, in this embodiment, a silicone pad 16 is provided on the top surface, and the silicone pad 16 is contoured to the bottom of the body 101, thereby ensuring that the body 101 can be tightly placed on the top of the placement seat 1, and also preventing damage to the product.

[0064] Furthermore, the top of the carrier 1 is provided with a first adsorption hole 141, and the silicone pad 16 is provided with a second adsorption hole 161. The first adsorption hole 141 and the second adsorption hole 161 are directly opposite each other, so that the product can be adsorbed on the carrier 1, thereby more effectively limiting the position of the product.

[0065] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments 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.
