[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 as to timely select unqualified products, improve the yield of the final product, and reduce production costs to a certain extent.

[0062] Embodiment 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 a CNC processing device to form a blank, opening at least one first processing hole 22 on the blank, and opening diagonally distributed first positioning holes 21 on the blank;

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

[0066] S113, using CNC processing equipment, sequentially processing the first processing holes 22 on the A surface of the blank to form a first processing groove 23 which is arranged on the outer side of the first processing hole 22 and is in an annular shape, and processing the inner wall of the first processing hole 22 to form the inner cavity of the upper part of the product, the first processing groove 23 forms the outer shape of the upper part of the product, and a diagonally distributed second positioning hole 24 is opened on the blank, the first positioning hole 21 and the second positioning hole 24 are distributed at the four corners of the blank, and a limiting groove 27 is opened on the outer surface of the blank to further position the blank; the blank is positioned in the X and Y directions using the first positioning hole 21, and the B surface is used as the positioning reference, that is, the B surface faces downward, and the flatness is controlled to be 0.08mm;

[0067] S114, after positioning through the second positioning holes 24, use CNC processing equipment to process the first processing holes 22 on the B surface of the blank to form two second processing holes 25 symmetrically arranged on both sides of the upper part of the inner cavity, the two second processing holes 25 respectively correspond to the opposite sides of one of the first processing grooves 23, and the two second processing holes 25 are respectively connected to the first processing grooves 23 along the Z direction; the blank is positioned in the X direction and the Y direction using the second positioning holes 24, and the A surface is facing downward as the positioning reference, and the flatness is controlled to be 0.08mm;

[0068] S115. After positioning through the second positioning hole 24, use CNC processing equipment to process 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 form a basic product, and form a boat-shaped end buckle 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 more compact and hard. This embodiment uses a plate-type aluminum extrusion with length, width, and height, with the length being in the X direction, the width being in the Y direction, and the height being 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 positioned and fixed from the side of the aluminum extrusion by an external clamp. The A surface can be used as the positioning reference facing downward, or the B surface can be used as the positioning reference facing downward. According to the minimum length and width of the inner cavity of the product, 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 from top to bottom. The first processing holes 22 can be two or four, and the number is determined by the size of the equipment and the aluminum extrusion. The first processing holes 22 can be distributed in a rectangular array, and a portion for processing the product shape should be reserved between two adjacent first processing holes 22. In this embodiment, the first positioning holes 21 are respectively opened along the Z direction at one of the two corners of the aluminum extrusion, and the processed aluminum extrusion is defined 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 surface B is ground with the surface A facing downward and the surface A is ground with the surface B facing downward in order to ensure the smoothness of the blank, thereby completing the roughing.

[0071] In step S113, when processing the first processing hole 22, the B surface is facing downward as the positioning reference, and the first positioning hole 21 is used for positioning. When processing the inner cavity of the first processing hole 22 from the A surface, for the convenience of processing, the processing of the inner cavity is only from the first open side 11 to the extension 14. The upper part of the inner cavity is located on the side of the A surface to form the first open side 11. A first step surface 13 is formed between the first open side 11 and the upper part of the inner cavity, and the second step surface 15 is not processed, thereby reducing the processing difficulty. The groove 16 in the inner cavity is partially opened. Since the outer shape parts on both sides of the product are streamlined, processing is easier, and the outer shape parts at both ends of the product are processed to the middle position of the outer shape at this time. For this reason, this processing is mainly for the processing of the top surface to the upper half of the product. In order to facilitate the processing of the bottom surface, the second positioning hole 24 is processed at the other diagonal of the blank on the basis of taking the B surface facing downward as the reference. Positioning grooves 182 may be provided along the Z direction on the 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 processing of the second positioning hole 24 is completed, the blank is turned over and positioned through the second positioning hole 24, at which time the B surface faces upward and the A surface faces downward as the positioning reference. The second processing hole 25 is only a rectangular parallelepiped structure at the beginning of the opening and penetrates the blank along the Z direction. The CNC processing equipment processes the product shape on the inner wall of the two second processing holes 25 on both sides of each first processing hole 22, and the second processing hole 25 is convenient for the CNC processing equipment to extend into it for shape processing. Then continue to position with the second positioning hole 24, so that the CNC processing equipment continues to process from the B surface, and the processing position is transferred to the two ends of the two second processing holes 25 and the B surface part between the second processing hole 25 and the first processing hole 22, and an extension part 14 is formed on the B surface and around the first processing hole 22. The inner side of the extension part 14 is connected to the upper part of the inner cavity to process the second step surface 15. At this time, the two ends of the part between the first processing hole 22 and the second processing hole 25 are still 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 to position with the second positioning hole 24 with the A side facing downward, and process from the B side from the two end positions of the first processing hole 22 to form an arc surface 171. At this time, the product has been completely disconnected 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 X and Y directions, and the side hole 19, buckle groove 181 and positioning groove 182 connected to the inner cavity are processed on the outer shape with the basic product A facing downward after blanking as the positioning reference. The buckle groove 181 and the positioning groove 182 are provided 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 as to facilitate the fixing column to control the flatness to 0.12mm.

[0076] Embodiment 2

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

[0078] S121, forming a blank with a third processing hole 26 by forging. In this step, the blank has a partial appearance of the product, including a streamlined outer wall portion, and the third processing hole 26 has a partial inner cavity structure of the product. The two sides of the blank distributed in the Z direction are the C surface 291 and the D surface 292 respectively;

[0079] S122, using CNC processing equipment to process the C surface 291 of the blank to form a product bottom surface and an 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 a product inner cavity;

[0081] S124, after being positioned through the third processing hole 26, use CNC equipment to process the outer wall of the blank to form an 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 step surface 13 have been formed on the blank C surface 291 and are connected to 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 0.12mm. Since the inner cavity needs to be processed, the second step surface 15 is used as the matching part for contact and 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 that contacts and positions 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. Inner cavity positioning is adopted in X and Y directions, with D surface 292 facing downward as the positioning reference, and the flatness is controlled to be 0.12 mm. The side hole 19, buckle groove 181 and positioning groove 182 connected to the inner cavity are processed on the outer shape.

[0088] Compared with the prior art, the processing method of the smart bracelet accessories 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 only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
