[0074] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0079] like Figures 1 to 7 As shown, an embodiment of the present application provides a method for forming a hole 4 on a product, wherein the product is provided with a groove 1, and the method for forming the hole 4 on the product includes:

[0080] S1, using a first tool 2 to open a hole 4 in the product that is connected to the groove 1, with the opening direction Z of the hole 4 being inclined relative to the transverse direction Y of the groove 1;

[0081] S2, using the first tool 2 to perform a first removal process along the circumference of the hole 4 with a first cutting amount to remove burrs generated when the hole 4 is opened;

[0082] S3, using the second tool 3 with a single-side blade size D2 larger than the single-side blade size D1 of the first tool 2 to perform a second burr removal process along the circumference of the hole 4 with a second cutting amount, the second cutting amount being larger than the first cutting amount.

[0083] Specifically, the product can be an electronic device, such as a mobile phone, a laptop computer, etc., or other types of devices, which are not limited here. The number of holes 4 opened on the groove 1 can be one, two or more. In the product, the sizes of the groove 1 and the holes 4 are relatively small, among which, Figure 7 As shown, the groove width T1 of the groove 1 can reach 0.75 mm. The aperture of the hole 4 opened on the groove 1 can reach 0.5 mm. The opening direction Z of the hole 4 can be parallel to the longitudinal direction of the groove 1, and have a preset angle with the transverse direction Y of the groove 1, that is, the hole 4 can be opened on the inclined groove 1. Step S1 is the roughing step of the hole 4. Burrs will be generated during this process, wherein the first tool 2 can be a milling cutter. In step S2, the first tool 2 can be used again to remove the burrs generated in step S1 for the first time. During the burr removal process, the first tool 2 can move clockwise along the circumferential direction of the hole 4, or move counterclockwise. In step S3, the second tool 3 used is different from the first tool 2. Specifically, the second tool 3 can be a directional chamfering tool. Along the length direction of the blade, the blade size of the second tool 3 on one side is D2, while the blade size of the first tool 2 on one side is D1, wherein D2 is greater than D1. Therefore, the second cutting amount can be greater than the first cutting amount. In the second removal process, the second tool 3 can also move along the circumferential direction of the hole 4, and the movement direction can be clockwise or counterclockwise.

[0084] like Figures 3 to 6 As shown, the first tool 2 includes a first cutting head 21, a first tool rod 22 and a first tool handle 23, and the second tool 3 includes a second cutting head 31, a second tool rod 32 and a second tool handle 33. In a specific embodiment, the structures of the first tool 2 and the second tool 3 are different, wherein the first tool 2 can be a double-edged tool, and the second tool 3 can be a single-edged tool, and the second tool 3 can be made by the first tool 2 through an eccentric tool process. Specifically, the second tool 3 can be based on the first tool 2, removing the blade structure on one side of the double-edged tool, and eccentrically setting the blade structure on the other side, that is, extending the blade structure as a whole outward. Therefore, compared with the original double-edged tool, the size of the single-edged tool head is reduced. However, due to the eccentric setting of the single-edged tool, the blade diameter of the single-edged tool is increased, thereby increasing the amount of burr cutting by the single-edged tool, so as to improve the burr cutting effect of the single-edged tool. As shown in FIG. Figure 5 and Figure 6As shown, the single-sided blade size of the first tool 2 is D1. When the first tool 2 is a double-edged tool, the single-sided blade size D1 is the size of one of the blade structures of the double-edged tool. The single-sided blade size of the second tool 3 is D2. When the first tool 2 is a single-edged tool, the single-sided single-edged size D1 is the size of the entire blade structure of the first tool 2. Blade size D1 can be smaller than blade size D2. Due to the influence of blade size, the first tool 2 has a smaller burr removal capacity, making it difficult for the first tool 2 to completely remove all burrs generated when opening the hole 4. Compared to the first tool 2, the second tool 3 has a larger single-sided blade size D2, which helps increase the burr removal capacity of the second tool 3, thereby improving the burr removal rate of the second tool 3. Specifically, in the first removal process, the first tool 2 can remove 0.05 mm of burrs, while in the second removal process, the second tool 3 can remove 0.12 mm of burrs. This embodiment is beneficial to improving the burr removal rate. At the same time, since the second tool 3 can be processed by the first tool 2, the possibility of needing to produce new tools is reduced, which is beneficial to reducing the production cost of the tool and further reducing the production cost of the product.

[0085] like Figure 7 As shown, in another possible embodiment, in addition to the above-mentioned groove 1, the product may also be provided with a processing groove 5, and the groove width dimension T2 of the processing groove 5 may reach 0.6 mm. The groove 1 and the processing groove 5 can be connected by opening the above-mentioned hole 4, wherein the opening direction Z of the hole 4 can be perpendicular to the transverse direction of the processing groove 5, that is, the groove 1 can be tilted relative to the processing groove 5. Among them, the first tool 2 can be used to rough the processing groove 5, and then the first tool 2 is moved along the opening direction Z of the hole 4 toward the direction close to the groove 1 to perform step S1. In this process, corresponding burrs will be generated at both ends of the hole 4, wherein the chamfer formed at the end of the hole 4 close to the processing groove 5 can be called a positive chamfer, and the burrs generated during the roughing process can be called positive chamfer burrs. Correspondingly, the chamfer formed at the end of the hole 4 close to the groove 1 can be called a reverse chamfer, and the burrs generated during the roughing process can be called reverse chamfer burrs. The first tool 2 and the second tool 3 can be inserted into the groove 1 through the hole 4 on the processing groove 5, and the reverse chamfer burrs can be removed through the above steps S2 and S3. Then the first tool 2 and the second tool 3 can be moved toward one side of the processing groove 5 to remove the forward chamfer burrs on one side of the processing groove 5.

[0086] In the related art, due to the limitations of factors such as the size of the hole 4, the size of the groove 1, the location of the hole 4, and the size of the tool, the burrs generated by the groove 1 of the product when the hole 4 is opened are difficult to remove, which will affect the processing quality of the hole 4 and the production quality of the product. Compared with the related art, the embodiment of the present application uses the first tool 2 and the second tool 3 to remove the burrs twice respectively, which is conducive to improving the burr removal rate and reducing the possibility of burr residue, thereby helping to improve the processing quality of the hole 4, and further helping to improve the quality of the processing and production of the product. At the same time, it is also conducive to reducing the possibility of using manual labor to remove the burrs, which is conducive to reducing labor costs, and thus helping to reduce the production cost of the entire product. On the other hand, the embodiment of the present application is also conducive to improving the utilization rate of the tool, so that the first tool 2 can realize both the function of rough processing and the function of burr removal, reducing the possibility of changing the tool in different operation steps, which is conducive to reducing the cost of using the tool, and helping to improve the processing efficiency of the hole 4.

[0087] like Figures 8 to 13 As shown, the above-mentioned reverse chamfer burrs can be formed at positions III and IV, the directions of paths A and C are parallel to the opening direction Z of hole 4, the directions of paths B and D are parallel to the transverse direction X of hole 4, the transverse direction X of hole 4 is perpendicular to the opening direction Z of hole 4, and there is a preset angle between the transverse direction Y of groove 1 and the opening direction Z of hole 4.

[0088] like Figures 8 to 10 As shown, in one possible embodiment, the groove 1 includes a first side wall 11 and a second side wall 12 arranged in sequence along the opening direction Z of the hole 4, and the hole 4 penetrates a portion of the first side wall 11 and communicates with the groove 1. Step S2 includes:

[0089] S21, the first tool 2 moves along the opening direction Z of the hole 4 toward the side close to the second side wall 12, so that the blade of the first tool 2 passes through the hole 4 and extends into the groove 1;

[0090] S22 , the first tool 2 moves toward the direction approaching the burr, so that the first tool 2 cuts the burr.

[0091] The hole 4 can be opened on the first side wall 11. In step S21, the first tool 2 can be moved along path A to a preset position in the groove 1. This position is the initial position of the first tool 2. At this time, the blade structure of the first tool 2 for cutting burrs can enter the interior of the groove 1 to prepare for the processing of removing the chamfered burrs. In step S22, the movement path of the first tool 2 can be set so that the first tool 2 can move along path A, path B, path C and path D. Specifically, the first tool 2 and the second tool 3 can be set on a mechanical device, and the mechanical device can control the first tool 2 and the second tool 3 through a preset program, so as to realize the directional movement of the tool.

[0092] This design can utilize the first tool 2 to achieve the first burr removal process, thereby helping to improve the burr removal rate and further helping to improve the quality of the processing and forming of the hole 4.

[0093] like Figures 8 to 10 As shown, in a possible embodiment, the burrs include a first burr and a second burr. Along the depth direction of the groove 1, the first burr and the second burr are respectively located on both sides of the hole 4. The distance between the first burr and the bottom wall 13 of the groove 1 is different from the distance between the second burr and the bottom wall 13 of the groove 1. Step S22 further includes:

[0094] S221, the first tool 2 moves along the transverse direction X of the hole 4 to below the first burr;

[0095] S222, the first tool 2 moves along the opening direction Z of the hole 4 toward the side close to the first side wall 11, so that the first tool 2 cuts the first burr;

[0096] S223, the first tool 2 moves along the opening direction Z of the hole 4 toward the side close to the second side wall 12;

[0097] S224, the first tool 2 moves along the transverse direction X of the hole 4 to below the second burr;

[0098] S225 , the first tool 2 moves along the opening direction Z of the hole 4 toward the side close to the first side wall 11 , so that the first tool 2 cuts the second burr.

[0099] like Figures 8 to 13As shown, the first burr can be formed at position IV, and the second burr can be formed at position III. Along the transverse direction Y of the groove 1, the first burr and the second burr can be located on both sides of the hole 4 respectively. Since there is a preset angle between the opening direction Z of the hole 4 and the transverse direction Y of the groove 1, the angle formed between the first burr and the first side wall 11 can be an acute angle, that is, the first burr can be an acute burr, and the angle formed between the second burr and the first side wall 11 can be an obtuse angle, that is, the second burr can be an obtuse burr. In step S2, the first tool 2 can remove the first burr first, or can remove the second burr first, and there is no limitation in the embodiment of the present application. The first tool 2 can be directed by setting a program, such as Figure 9 As shown, in the groove 1, the first tool 2 can first move along the path B to the bottom of the first burr, and then the first tool 2 can move along the path C toward the direction close to the first burr and cut the first burr. Figure 10 As shown, the first tool 2 can first be reset. That is, after cutting the first burr, the first tool 2 can first move along path A and then move along path D to restore to the initial position in step S21. Then, the first tool 2 can continue to move along path D to below the second burr, and then move along path C in a direction close to the second burr to cut the second burr.

[0100] During the movement of the first tool 2 along the circumferential direction of the hole 4, the first burr and the second burr on both sides of the hole 4 can be removed for the first time. In the first removal process, the removal effect of the sharp-angled burrs is more obvious, while the removal of the obtuse-angled burrs is more difficult. The first tool 2 cannot completely remove the obtuse-angled burrs, so it is necessary to use the second tool 3 to perform a second burr removal process. In steps S221 to S225, by setting the movement path of the first tool 2, the first tool 2 can perform targeted cutting and removal of the first burr and the second burr, reducing the possibility of burrs remaining at the hole 4, which is conducive to improving the burr removal rate, and thus is conducive to improving the processing quality of the hole 4.

[0101] In a possible implementation, after the first tool 2 cuts the second burr, step S2 further includes:

[0102] S23 , chamfering the hole 4 using the first tool 2 .

[0103] In step S2, the size of the chamfer produced by the first tool 2 when removing burrs cannot meet the process requirements of hole 4. Therefore, in step S23, the first tool 2 can be used to further chamfer hole 4, thereby facilitating the production of a chamfer that meets the process requirements. This design further improves the utilization rate of the first tool 2, that is, the first tool 2 can have the functions of roughing, deburring, and chamfering. On the other hand, chamfering hole 4 is not only conducive to removing burrs, improving the processing quality of hole 4, and reducing the possibility of burrs scratching other parts, but also facilitates the subsequent use of hole 4 and facilitates the coordination of hole 4 with other parts.

[0104] In a possible implementation, in step S23:

[0105] The first tool 2 moves along the circumference of the hole 4 and simultaneously moves along the opening direction Z of the hole 4 .

[0106] When using the first tool 2 to chamfer the hole 4, since the groove 1 is inclined, there is a height difference between the two ends of the hole 4 along the transverse direction Y of the groove 1. Therefore, the movement path of the first tool 2 needs to move not only along the circumference of the hole 4, but also along the opening direction Z of the hole 4. Specifically, the first tool 2 can chamfer the hole 4 in a clockwise direction or in a counterclockwise direction.

[0107] By limiting the moving path of the first tool 2 , it is beneficial to make the hole 4 have a complete chamfer, further beneficial to improving the processing quality of the hole 4 , and facilitating the assembly of the hole 4 with other parts.

[0108] like Figures 11 to 13 As shown, in a possible implementation, step S3 includes:

[0109] S31, the second tool 3 moves along the opening direction Z of the hole 4 toward the side close to the second side wall 12, so that the blade of the second tool 3 extends into the groove 1;

[0110] S32 , the second tool 3 moves toward the direction approaching the first burr and the second burr, so that the second tool 3 cuts the first burr and the second burr, respectively.

[0111] Because the first tool 2 cannot completely remove the burrs, a second burr removal process is required using the second tool 3. In step S31, the second tool 3 moves along path A to its initial position within the groove 1, so that the cutting edge for cutting burrs extends into the groove 1. In step S32, the second tool 3 can remove the first burr and the second burr respectively. Since the single-sided blade size D2 of the second tool 3 is larger and the cutting volume is larger, it can achieve a more significant burr removal effect.

[0112] In the embodiment of the present application, the burrs can be removed for a second time using a second tool 3 with a larger cutting amount, thereby improving the burr removal efficiency and reducing the possibility of burr residue, which is beneficial to improving the processing quality of the hole 4 and the production quality of the entire product.

[0113] like Figures 11 to 13 As shown, in a possible implementation, step S32 includes:

[0114] S321, the second tool 3 moves along the transverse direction X of the hole 4 to below the first burr;

[0115] S322, the second tool 3 moves along the opening direction Z of the hole 4 toward the side close to the first side wall 11, so that the second tool 3 cuts the first burr;

[0116] S323, the second tool 3 moves along the opening direction Z of the hole 4 toward the side close to the second side wall 12;

[0117] S324, the second tool 3 moves along the transverse direction X of the hole 4 to below the second burr;

[0118] S325 , the second tool 3 moves along the opening direction Z of the hole 4 toward the side close to the first side wall 11 , so that the second tool 3 cuts the second burr.

[0119] In step S3, the second tool 3 may remove the first burr first, or may remove the second burr first, which is not limited in the embodiment of the present application. Figure 12 As shown, the second tool 3 can move along the path B to the bottom of the first burr, and then move along the path C in the direction close to the first burr to cut the first burr. In step S323 to step S324, as shown in FIG. Figure 13 As shown, after cutting the first burr, the second tool 3 can move along path A and then along path D to return to the initial position in S31. That is, after cutting the first burr, the second tool 3 needs to first perform a reset action, then move along path D to below the second burr, and then move along path C toward the second burr to cut the second burr.

[0120] By setting the moving path of the second tool 3, the second tool 3 can perform targeted cutting and removal of the first burr and the second burr, which is further beneficial to improving the burr removal rate, thereby further improving the processing and forming quality of the hole 4, and improving the quality of the entire product production and processing.

[0121] In a possible embodiment, after step S3, the method for forming the hole 4 on the product further includes:

[0122] S4, performing sandblasting on hole 4.

[0123] After the first and second removal processes, the hole 4 can be sandblasted using a sandblasting device. The sandblasting process can also remove burrs and polish the hole 4. The sandblasting process is beneficial to further improve the burr removal rate and improve the quality of the processing of the hole 4.

[0124] In a possible implementation, in step S2:

[0125] The first right-handed cutting tool 2 is used to remove chips toward the side close to the first side wall 11 of the groove 1 when cutting burrs.

[0126] When the first tool 2 is cutting the burrs, the first tool 2 can discharge the chips upward, that is, discharge the cut chips to the side close to the first side wall 11.

[0127] This arrangement is beneficial to reducing the possibility of debris depositing at the bottom of the groove 1, thereby reducing the possibility of the debris affecting the operation of the first tool 2, and is beneficial to the burr removal work.

[0128] In a possible implementation, in step S3:

[0129] The second tool 3 that rotates left and cuts right is used to remove chips toward the side close to the second side wall 12 of the groove 1 when cutting burrs.

[0130] The chip removal direction of the second tool 3 is opposite to that of the first tool 2, that is, the second tool 3 removes chips downward. The design of the two tools removing chips in opposite directions is conducive to improving the tool's burr removal effect, that is, the burr can be affected from two directions, thereby improving the quality of the processing of the hole 4.

[0131] In one possible embodiment, the method for forming the hole 4 on the product includes:

[0132] S5, using a first tool 2 including at least one blade to open a hole 4 on the product, and performing a first removal process on burrs generated when opening the hole 4 with a first cutting amount;

[0133] S6, using a second tool 3 including one blade to perform a second burr removal process with a second cutting amount.

[0134] The second tool 3 can be an eccentric tool with one blade, specifically, a directional single-edge dovetail tool, and the first tool 2 can be a single-edge tool, specifically, a single-edge milling cutter or a single-edge drill, or the first tool 2 can also be a double-edge tool, a three-edge tool or a multi-edge tool, which is not limited here.

[0135] In a specific embodiment, both the first tool 2 and the second tool 3 may be single-edged tools, but the structure of the first tool 2 differs from that of the second tool 3. Specifically, the second tool 3 may be an eccentric tool, whose blade structure may be extended outward by an eccentric arrangement, thereby increasing the size of the blade structure and thereby increasing the cutting capacity of the second tool 3. The first tool 2, on the other hand, is a single-edged tool without an eccentric arrangement. Therefore, the blade size D2 of the second tool 3 may be larger than the blade size D1 of the first tool 2. Specifically, D2 may be 0.05 mm larger than D1, thereby increasing the cutting capacity of the second tool 3.

[0136] In the related art, an integrated tool is used to perform roughing, deburring, and other processes on the hole 4 during the forming process. However, the integrated tool is relatively large in size, and due to its own size limitation, the burr removal effect is poor, which not only affects the processing quality of the hole 4, but also affects the processing quality of the entire product. In the implementation of this application, two tools can be used, wherein the first tool 2 is used to perform roughing, chamfering, and the first burr removal process on the hole 4, and the second tool 3 is used to perform the second burr removal process, wherein the second tool 3 can have a larger cutting amount and has a better removal effect on both obtuse burrs and acute burrs. Compared with the current integrated tool, the sizes of the first tool 2 and the second tool 3 are relatively small, and there are fewer restrictions on the burr removal process. Therefore, the embodiment of the present application is conducive to improving the burr removal rate, thereby helping to improve the quality of the forming process of the hole 4, and further helping to improve the quality of the processing and production of the entire product.

[0137] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
