A positioning base 2 is provided on the top of the jig base 1, and an X-axis positioning block 3 is slidably provided on the positioning base 2. The X-axis positioning block 3 is slidably provided with a Y-axis positioning block 4, and the Y-axis positioning block 4 is rotatably provided with an R-axis positioning block 5; a connecting piece is provided on the R-axis positioning block 5, and a clamping assembly for positioning the mobile phone mid-plate is provided on the connecting piece;

[0025] X-axis adjustment blocks 21 are provided at both ends of the positioning base 2, and Y-axis adjustment blocks 31 are provided at both ends of the X-axis positioning block 3; the X-axis adjustment block 21 is provided with an X-axis adjustment member 22 abutting against the X-axis adjustment block 21, and the Y-axis adjustment block 31 is provided with a Y-axis adjustment member 32 abutting against the Y-axis positioning block 4; a first positioning hole 41 is provided on the Y-axis positioning block 4, and adjustment holes 51 are provided at both ends of the R-axis positioning block 5, and a first R-axis positioning member 52 is connected between the adjustment hole 51 and the first positioning hole 41.

[0026] Specifically, in actual use, the multi-axis adjustment jig for polishing the middle plate of a mobile phone described in this embodiment is clamped and fixed on the clamping assembly, and then the two X-axis adjusting members 22 in the X-axis direction drive the X-axis positioning block 3 to move along the positive and negative directions of the X-axis, thereby adjusting the position of the middle plate of the mobile phone in the X-axis direction through the Y-axis positioning block 4, the R-axis positioning block 5, the connecting member and the clamping assembly, and the two Y-axis adjusting members 32 in the Y-axis direction drive the Y-axis positioning block 4 to move along the positive and negative directions of the Y-axis, thereby adjusting the position of the middle plate of the mobile phone in the Y-axis direction through the R-axis positioning block 5, the connecting member and the clamping assembly, and by rotating the R-axis positioning block 5, the position of the middle plate of the mobile phone in the R-axis direction is adjusted through the connecting member and the clamping assembly. After the position of the middle plate of the mobile phone in the R-axis direction is adjusted into place, the first R-axis positioning member 52 passes through the adjustment hole 51 and cooperates with the first positioning hole 41 to fix the R-axis positioning block 5, thereby realizing multi-axis adjustment of the middle plate of the mobile phone.

[0027] In this embodiment, an X-axis positioning block 3 and a Y-axis positioning block 4 are slidingly arranged, and an R-axis positioning block 5 is rotatably arranged, and X-axis adjustment members 22 are arranged at both ends of the positioning base 2, Y-axis adjustment members 32 are arranged at both ends of the X-axis positioning block 3, and first R-axis positioning members 52 are arranged at both ends of the R-axis positioning block 5. Therefore, the position of the mobile phone middle plate can be adjusted in the positive and negative directions respectively through the X-axis adjustment member 22, the Y-axis adjustment member 32 and the first R-axis positioning member 52, so that the position of the mobile phone middle plate after adjustment is more stable, effectively preventing the mobile phone middle plate from positional deviation during the polishing process, improving the polishing accuracy and product yield of the mobile phone middle plate, and also helping to reduce the replacement frequency of the polishing head and reduce production costs.

[0029] In actual use, by screwing the X-axis cylindrical screw and the Y-axis cylindrical screw, the X-axis positioning block 3 and the Y-axis positioning block 4 are moved respectively, so that the position of the mobile phone middle plate in the X-axis direction and the Y-axis direction can be adjusted; when it is necessary to adjust the position of the mobile phone middle plate in the R-axis direction, the R-axis positioning bolt is screwed to loosen the R-axis positioning block 5, and then the R-axis positioning block 5 can be rotated to adjust the position of the mobile phone middle plate. After the adjustment is completed, the R-axis positioning bolt is screwed again so that the R-axis positioning bolt presses the R-axis positioning block 5, so that the R-axis positioning block 5 remains in the adjusted position, thereby effectively preventing the position of each positioning block from shifting during the grinding process, thereby effectively improving the grinding accuracy.

[0030] like Figures 1 to 3 As shown, in some embodiments of the multi-axis adjustment jig for polishing a mobile phone mid-plate, the connecting member is an electromagnet 6.

The clamping base 71 and the clamping cover 72 cooperate to fix the middle plate of the mobile phone in the clamping space.

[0036] Specifically, in actual use, the mobile phone middle plate is placed in the clamping space, and then the clamping cover 72 is fixed on the clamping base 71, so as to fix the mobile phone middle plate in the clamping space for polishing the mobile phone middle plate.

[0037] like Figures 1 to 4 As shown, in the embodiment of the multi-axis adjustment jig for polishing the middle plate of a mobile phone, in some embodiments, a handle 73 is provided on the clamping cover 72. In this embodiment, the handle 73 is provided to facilitate the operation of clamping the cover 72.
