The inner cavity is rectangular and has rounded corners. The smart bracelet accessory has a top surface and a bottom surface. The inner cavity extends through the top surface in the Z direction to form a first open side 11. The length direction of the body is arranged along the X direction. Both sides of the first open side 11 in the X direction (hereinafter referred to as "the two ends of the body") are curved toward the side away from the body to form a boat-shaped opening. A first annular groove 12 is recessed around the inner cavity on the first open side 11. The first annular groove 12 extends inward through the inner cavity in the X and Y directions and extends through the top surface in the Z direction. A first step surface 13 is formed between the first annular groove 12 and the inner cavity. On one side of the through-bottom surface of the inner cavity a, an extension 14 is provided, extending around the inner wall of the inner cavity. A second open side 28 and a second stepped surface 15 are formed between the extension 14 and one side of the through-bottom surface, making it easier to place other items in the inner cavity a during assembly of the smart bracelet accessory. The extension 14 and the second stepped surface 15 are used to support the items. Several grooves 16 are recessed into the inner wall of each side of the inner cavity a, each groove 16 positioned at the same height. The outer wall of the body is streamlined, with both ends of the body projecting away from the body in the middle of the Z direction. End grooves 20 are provided at both ends of the body and extending from the bottom surface of the body. End grooves 20 extend from the bottom surface in the Z direction, extending in opposite directions along the X direction, forming an overall boat-shaped end buckle 17 at each end of the body.

[0056] S1. Use CNC processing equipment to process the inner cavity and outer shape of the product on the blank;

[0057] S2, grinding the processed blank;

[0058] S3, transferring the processed blank to a CNC processing device to process the side hole 19 of the product;

[0059] S4, sandblasting the processed blank;

[0060] S5. Anodize the processed blank surface to form the smart bracelet accessory.

[0061] According to the above method, the structures of various parts of the smart bracelet accessories can be processed in sequence, and cleaning and full inspection are carried out after each processing, so that unqualified products can be selected out in time, the yield of the final product can be improved, and the production cost can be reduced to a certain extent.

[0062] Example 1

[0063] Please refer to Figures 4 to 12 , the S1 step includes the following sub-steps:

[0064] S111, roughing the aluminum extrusion material through CNC processing equipment to form a blank, forming at least one first processing hole 22 on the blank, and forming diagonally distributed first positioning holes 21 on the blank;

[0065] S112, performing DDG double-sided grinding on the blank;

[0066] S113, using CNC machining equipment, sequentially machining first machining grooves 23 in an annular shape surrounding the outer sides of the first machining holes 22 on the blank A side, and machining from the inner walls of the first machining holes 22 to form the inner cavity of the upper portion of the product, the first machining grooves 23 forming the outer shape of the upper portion of the product, and providing diagonally distributed second positioning holes 24 on the blank, the first positioning holes 21 and the second positioning holes 24 distributed at the four corners of the blank, and providing limiting grooves 27 on the outer side of the blank to further position the blank; the blank is positioned in the X and Y directions using the first positioning holes 21, and the B side is used as the positioning reference, that is, the B side faces downward, and the flatness is controlled to be 0.08 mm;

[0067] S114. After positioning through the second positioning holes 24, use CNC processing equipment to machine two second processing holes 25 symmetrically located on both sides of the upper portion of the inner cavity from the first processing holes 22 on the blank surface B. The two second processing holes 25 correspond to opposite sides of one of the first processing grooves 23, and the two second processing holes 25 are connected to the first processing grooves 23 along the Z direction. The blank is positioned in the X and Y directions using the second positioning holes 24, with the A surface facing downward as the positioning reference, and the flatness is controlled to be 0.08 mm.

[0068] S115. After positioning through the second positioning hole 24, use CNC processing equipment to perform processing from the B side of the blank and at the other two opposite sides of the inner cavity a corresponding to the first processing groove 23 to blank the material to form a basic product, and form boat-shaped end buckles 17 at both ends of the basic product; the blank is positioned in the X and Y directions using the second positioning hole 24, and the A side is facing downward as the positioning reference, and the flatness is controlled to be 0.12mm.

[0069] In step S111, the use of aluminum extrusion has the advantages of being denser and harder. This embodiment uses plate-type aluminum extrusion with length, width, and height, with length in the X direction, width in the Y direction, and height in the Z direction. The size of the aluminum extrusion is 124mm×77mm×11.4mm. During processing, the flatness is controlled to be 0.2~0.08mm so that several metal smart bracelet accessories can be processed on the aluminum extrusion. The top surface of the aluminum extrusion is defined as surface A, and the bottom surface of the aluminum extrusion is defined as surface B. When roughing, the side is used for positioning and it is fixed from the side of the aluminum extrusion by an external clamp. The A side can be used as the positioning reference facing downward, or the B side can be used as the positioning reference facing downward. According to the minimum length and width of the product cavity, at least two first processing holes 22 are opened in the aluminum extrusion along the Z direction. Each first processing hole 22 has a rectangular structure and is through-through from top to bottom. The number of first processing holes 22 can be two or four, depending on the equipment and the size of the aluminum extrusion. The first processing holes 22 can be spaced apart in a rectangular array, with space reserved between adjacent first processing holes 22 for processing the product's shape. In this embodiment, first positioning holes 21 are provided along the Z direction at a pair of corners of the aluminum extrusion, defining the processed aluminum extrusion as a blank.

[0070] In step S112, the blank is positioned through the first positioning hole 21 so that the flatness of the blank is controlled to be 0.03 mm, and the B surface is ground with the A surface facing downward and the A surface is ground with the B surface facing downward in order to ensure the smoothness of the blank, thereby completing the roughing.

[0071] In step S113, when machining the first machining hole 22, the B side is facing downward as the positioning reference, and the first positioning hole 21 is used for positioning. When machining the inner cavity of the first machining hole 22 from the A side, for the sake of simplicity of machining, the inner cavity is only machined from the first open side 11 to the extension 14. The upper inner cavity is located on the side of the A side to form the first open side 11. A first step surface 13 is formed between the first open side 11 and the upper inner cavity, and the second step surface 15 is not machined, thereby reducing the difficulty of machining. The groove 16 in the inner cavity is partially opened. Since the outer shape of the product on both sides is streamlined, machining is easier, and the outer shape of the product at both ends is machined to the middle position of the outer shape at this time. For this reason, this machining mainly involves machining from the top surface to the upper half of the product. In order to facilitate the machining of the bottom surface, a second positioning hole 24 is machined at the other diagonal corner of the blank based on the B side facing downward. Positioning grooves 182 may be provided along the Z direction on all four sides of the blank, and the positioning grooves 182 are connected toward the side away from the blank, so as to facilitate the external positioning mechanism to fix the blank.

[0072] In step S114, after the second positioning holes 24 are machined, the blank is flipped over and positioned using the second positioning holes 24. At this point, the B side faces upward and the A side faces downward as a positioning reference. Initially, the second machining holes 25 are merely rectangular and penetrate the blank in the Z direction. The CNC machining equipment machines the product's shape on the inner wall of the two second machining holes 25 on either side of each first machining hole 22, facing each other. The second machining holes 25 facilitate the CNC machining equipment's insertion into the B side for machining. Subsequently, the second positioning holes 24 are used for positioning, allowing the CNC machining equipment to continue machining from the B side. The machining position is then transferred to the ends of the two second machining holes 25 and the portion of the B side between the second machining holes 25 and the first machining hole 22. An extension 14 is formed on the B side and around the first machining hole 22. The inner side of the extension 14 communicates with the upper portion's inner cavity to machine the second step surface 15. At this point, the ends of the portion between the first machining hole 22 and the second machining hole 25 remain connected to the blank. The upper inner cavity and the lower inner cavity are distributed in the Z direction, and together they form the inner cavity a of the product; the upper outer shape and the lower outer shape are distributed in the Z direction, and together they form the outer shape b of the product.

[0073] In step S115, continue positioning with the second positioning hole 24 with surface A facing downward, and process from the B surface at both ends of the first processing hole 22 to form an arc surface 171. At this time, the product has been completely separated from the blank and blanked, and the end buckles 17 at both ends are formed, thereby completing the processing of the basic product.

[0074] The S5 step includes the following sub-steps:

[0075] S51. Inner cavity positioning is adopted in the X and Y directions, and the side hole 19, buckle groove 181 and positioning groove 182 connected to the inner cavity are respectively processed on the outer shape with the basic product A facing downward after blanking. The buckle groove 181 and the positioning groove 182 are opened on the arc surface 171. At this time, the first step surface 13 is used to facilitate positioning and support with the external positioning structure, so that the fixed column can control the flatness to 0.12mm.

[0076] Example 2

[0077] Please refer to Figures 15 to 22 , the S1 step includes the following sub-steps:

[0078] S121. Form a blank having a third machining hole 26 by forging. In this step, the blank already has a partial shape of the product, including a streamlined outer wall portion. The third machining hole 26 has a partial inner cavity structure of the product. The two sides of the blank in the Z direction are C surface 291 and D surface 292 respectively.

[0079] S122, using CNC processing equipment to process the C surface 291 of the blank to form the product bottom surface and the end buckle 17;

[0080] S123, after positioning through the third processing hole 26, use CNC equipment to process the inner wall of the third processing hole 26 from the D surface 292 to form the product inner cavity;

[0081] S124 , after positioning through the third processing hole 26 , use CNC equipment to process the outer wall of the blank to form the outer shape.

[0082] In step S121 , the size of the blank may be 45.86 mm×19.3 mm×11.36 mm, wherein the length and width are based on the C-surface 291 . The first open side 11 and the first stepped surface 13 are already formed on the C-surface 291 of the blank and communicate with the third processing hole 26 .

[0083] In step S122, positioning is performed in the X and Y directions through the third processing hole 26, and in the Z direction, the D surface 292 is facing downward and the C surface 291 is facing upward. The flatness is controlled to be 0.08 mm; the second step surface 15, the extension portion 14 and part of the inner cavity are processed in sequence, and then end grooves 20 are opened at both ends of the blank to form end buckles 17.

[0084] In step S123, positioning is performed through the third processing hole 26, and the C surface 291 is facing downward as the positioning reference, and the flatness is controlled to be 0.12 mm. Since the inner cavity needs to be processed, the second step surface 15 is used as the matching part for contact positioning with the positioning structure, and the first step surface 13, the remaining part of the inner cavity and the groove 16 are processed in sequence until the extension part 14 is processed, thereby processing the product inner cavity structure in the Z direction.

[0085] In step S124, continue to position with the third processing hole 26 and make the D surface 292 face downward as the positioning reference, control the flatness to 0.12mm, fix the blank through the second step surface 15 as the part for contact and positioning with the positioning structure, and continue to process the product shape from the C surface 291 to complete the remaining shape part, thereby forming the basic product.

[0086] The S3 step includes the following sub-steps:

[0087] S31. Use inner cavity positioning in the X and Y directions, make the D surface 292 downward as the positioning reference, control the flatness to 0.12mm, and process the side hole 19, buckle groove 181 and positioning groove 182 connected to the inner cavity on the outer shape.

[0088] Compared with the prior art, the smart bracelet accessory processing method of the present invention can basically complete the processing of the inner cavity and the outer shape from the Z-direction movement, simplifying the processing difficulty, and can select different processing methods according to actual conditions, so as to adopt the best processing method to complete product molding; the setting of the extension part 14 forms the second step surface 15 and the first step surface 13 to facilitate positioning from the inner cavity in many processing steps, preventing external positioning structures or equipment from affecting the processing of the outer shape.

[0089] The above embodiments merely represent preferred embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
