DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 3 The present invention provides a diamond polishing fixture, comprising a housing 1, two oppositely arranged clamping plates 2, a locking mechanism 3 and an unlocking mechanism 4. The housing 1 is a box body with an opening at the top, other components are arranged in the housing 1, and a hinge seat 11 is also arranged inside the housing 1.

[0034] The bottom of the clamping plate 2 is hinged to the hinge seat 11 in the outer shell 1, and the tops of the clamping plates 2 on both sides can be rotated in the same plane to achieve the clamping and loosening of the tops of the clamping plates 2; a step structure 21 is provided on the inner side of the top of the clamping plate 2, and an inner cover shell 5 is provided on the outer side of the clamping plate 2. The top shape of the inner cover shell 5 is adapted to the shape of the diamond to be clamped, and the step structures 21 on both sides and the inner cover shell 5 are arranged to form a mounting groove 6 for accommodating the diamond. Figure 4 As shown, before locking, the tops of the two side clamps 2 are in a relaxed state, and the diamond can be freely placed in the installation groove 6; and when the two side clamps 2 are in a clamped state, the diamond is firmly fixed in the installation groove 6.

[0035] In order to achieve the clamping of the two side clamps 2, the outer side of the inner shell 5 is equipped with a limit block 7, and the locking mechanism 3 is an annular plate whose inner surface is in contact with the outer surface of the inner shell 5, and is sleeved on the outer surface of the inner shell 5; the contacting part of the locking mechanism 3 and the inner shell 5 is bent inward, so that the contact position of the two is relatively fixed; the bottom of the locking mechanism 5 is provided with a hook part 31 for hooking the limit block 7. Specifically, as Figure 5 As shown, the upper side of the limit block 7 is provided with a first inclined surface 71, and the lower side of the hook portion 31 is provided with a second inclined surface 311; during the locking process, the first inclined surface 71 and the second inclined surface 311 are in contact with each other, and as the locking mechanism 3 descends, the first inclined surface 71 pushes the hook portion 31 outward. The hook portion is made of elastic material, and the first inclined surface 71 and the second inclined surface 311 make it easy for the locking mechanism to descend.

[0036] In order to unlock the locking mechanism in the locked state, the unlocking mechanism 4 is arranged directly below the hook 3 to unlock the hook from the limit block; in order to realize the installation and movement of the unlocking mechanism 4, the bottom of the housing 1 is provided with a through hole 12 for the bottom of the unlocking mechanism 4 to pass through. Figure 3 and Figure 6 , the width of the hook portion 31 is greater than the width of the limit block 7 so that there are remaining extensions on both sides of the hook portion, and a third inclined surface 42 is provided on the top of the unlocking mechanism 4, which is directly below the extension. During the unlocking process, the third inclined surface 42 fits with the second inclined surface 311. As the unlocking mechanism 4 rises, the third inclined surface 42 pushes the hook portion 311 outward until the hook portion 31 is disengaged from the limit block to achieve unlocking. It is worth mentioning that corresponding to the remaining portions on both sides of the hook portion, two corresponding unlocking mechanisms 4 are provided under the same hook portion. In order to achieve synchronous movement of the two, the two unlocking mechanisms 4 are connected by a connecting portion 41 to form a stable H-shaped structure.

[0037] Please refer to Figure 7 and Figure 8 , and further includes a polishing plate 8, on which a through hole 81 for exposing the diamond 9 is provided, and a sink 82 for installing the housing 1 is provided at the bottom of the through hole 81, and a plurality of inverted first folded edges 83 are provided at the lower part of the sink 82. The top of the housing 1 is provided with a plurality of outward-turned second folded edges 13, and the second folded edges 13 are inserted into the sink 82 from the gap position between two adjacent first folded edges 83. When installing, the second folded edges 13 are aligned with the gap position between two adjacent first folded edges 83, thereby extending into the sink and rotating the housing by a specified angle, and the second folded edges 13 are buckled by the first folded edges 83 in the vertical direction to achieve installation.

[0038] This embodiment also provides a clamping method of the diamond polishing fixture as described above, characterized in that it includes the following steps:

[0039] S1. The diamond is placed in the mounting groove between two oppositely arranged clamping plates;

[0040] S2, the locking mechanism is sleeved on the outer surface of the inner cover shell and pressed down until the hook part hooks the limit block;

[0041] S3, the second folded edge is aligned with the gap between two adjacent first folded edges and extends into the sink;

[0042] S4, rotating the housing at a specified angle, so that the first folded edge clamps the second folded edge;

[0043] S5. After polishing is completed, the shell is rotated in the reverse direction at a specified angle to separate the shell from the sink;

[0044] S6, the unlocking mechanism moves upward, causing the hook to disengage from the limit block;

[0045] S7, the locking mechanism is disengaged upward from the inner cover to achieve unlocking;

[0046] S8. Take out the diamond.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
