[0002] In the utility model patent application with application publication number CN220971397U, it includes an operating table, a drill bit and a rotating motor. The end of the output shaft of the rotating motor is fixedly installed with a connecting rod through an electric drill chuck, the end of the connecting rod is fixedly connected to the drill bit, and the outer surface of the connecting rod is slidably sleeved with a grinding sleeve, and the outer surface of the connecting rod is fixedly sleeved with a limiting sleeve at a position above the grinding sleeve.
[0003] The advantages are: the utility model can grind the hole wall during the process of punching the back cover of the mobile phone, thereby improving the smoothness of the hole wall, facilitating subsequent use, reducing the subsequent grinding process, and improving production and processing efficiency.
[0004] In the prior art including the above-mentioned patents, when the drill bit is drilling a hole in the back cover of a mobile phone, since the hole needs to be drilled at a precise position, the equipment cannot have any errors when drilling. If an error occurs, it will easily cause the parts installation position of the back cover to be misaligned during subsequent production, resulting in the back cover of the mobile phone being scrapped. Therefore, when the drill bit is drilling a hole, the drilling position needs to be accurately positioned in advance. At the same time, the drill bit may deviate slightly when drilling, causing the inner wall of the hole to deviate. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are: the precise hole-making equipment for manufacturing the back cover of a mobile phone is reasonable and has the following advantages:
[0013] (1) The present invention improves the accuracy of drilling by opening a reserved hole on the back cover of a mobile phone. In the traditional drilling process, the drill bit directly contacts the surface of the material, which is prone to offset, resulting in inaccurate drilling position. The auxiliary hole opening block in the present device is designed to be conical, which leaves a small depression on the back cover when it contacts the back cover of the mobile phone. This small depression serves as a reserved point for drilling and provides a clear starting position for the drill bit. This design provides the drill bit with an accurate positioning reference when it starts drilling, thereby reducing offset during the drilling process and improving the accuracy of drilling. This is particularly important for the manufacturing of mobile phone back covers that have extremely high precision requirements during the manufacturing process, and can effectively improve product quality and processing efficiency.
[0014] (2) Due to the conical design of the auxiliary hole-opening block, it first contacts the back cover of the mobile phone when pressed down, forming a small depression. This small depression not only provides a starting point for drilling, but also helps to fix the position of the drill bit, reducing the swing or deviation of the drill bit during the drilling process. When the drill bit starts drilling, the inner wall of the auxiliary hole-opening block contacts one end of the drill bit, so that the auxiliary hole-opening block is stretched from the inside out, further stabilizing the position of the drill bit. This mechanism ensures the stability of the drill bit during the drilling process, so that each drill hole can maintain consistent quality and precision, reducing the scrap rate caused by drilling deviation, and improving production efficiency and product consistency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:
[0023] In this embodiment, a precision hole-making device for manufacturing a mobile phone back cover includes a drilling device 1, which includes a slider 101. A drill bit 102 is installed at the bottom of the slider 101, a top block 103 is installed on one side of the drill bit 102, a connecting telescopic rod 104 is installed on the outer wall of the top block 103, a pressure spring 105 is installed around the outer wall of the connecting telescopic rod 104, one end of the connecting telescopic rod 104 is connected to a bottom block 106, a connecting plate 107 is installed on the outer wall of the bottom block 106, a side block 108 is installed at the bottom of the outer wall of the connecting plate 107, a pressure telescopic rod 109 is installed on the outer wall of the side block 108, a support spring 110 is installed around the outer wall of the pressure telescopic rod 109, a docking block 111 is installed on one end of the pressure telescopic rod 109, and an auxiliary hole-making block 112 is connected to the outer wall of the docking block 111.
[0024] In this embodiment, a dust collection assembly 2 is installed on one side of the outer wall of the connecting plate 107, and the dust collection assembly 2 includes a side panel 201. A dust collector 202 is installed on one side of the outer wall of the side panel 201. A downward pressing assembly 3 is installed on the top of the outer wall of the slider 101, and the downward pressing assembly 3 includes a telescopic cylinder 301.
[0025] In this embodiment, the output end of the telescopic cylinder 301 is connected to a connecting rod 302, and a shell 4 is provided on the top of the telescopic cylinder 301. The shell 4 includes a body 401, and the inner wall of the body 401 is provided with a column 402, and the outer wall of the column 402 is provided with a placement platform 403.
[0026] In this embodiment, a cavity is provided on one side of the connecting plate 107 , and the diameter of the cavity of the connecting plate 107 is adapted to the diameter of the drill bit 102 . The cavity of the connecting plate 107 enables the connecting plate 107 to move along the outer wall of the drill bit 102 .
[0027] In this embodiment, the auxiliary hole-opening block 112 is conical in three-dimensional view, and is separated. The auxiliary hole-opening block 112 can be opened by the drill bit 102 .
[0028] In this embodiment, the inner wall of the auxiliary hole-opening block 112 is hollow, and the outer wall of the auxiliary hole-opening block 112 is connected to the docking block 111 . The auxiliary hole-opening block 112 can be opened by the drill bit 102 .
[0029] Working principle: When in use, the user first places the back cover of the mobile phone on the placement table 403, then starts the drill bit 102 and the telescopic cylinder 301 at the same time. After the telescopic cylinder 301 is started, the connecting rod 302 will be driven to move, and the connecting rod 302 will drive the slider 101 to move downward. After the slider 101 moves, the drill bit 102 will be pressed downward, thereby drilling a hole in the back cover of the mobile phone. When the drill bit 102 is pressed down, the first thing to contact the back cover of the mobile phone is not the drill bit 102 but the auxiliary hole-opening block 112. Because the auxiliary hole-opening block 112 is conical, the auxiliary hole-opening block 112 will leave a small depression on the back cover of the mobile phone when it contacts the back cover of the mobile phone. This small depression helps the drill bit 102 to form a reserved point when drilling, so that the drill bit 102 will not deviate during drilling and can also assist the drill bit 102 in positioning drilling, thereby improving drilling accuracy.
[0030] Secondly, when the auxiliary hole block 112 is continuously pressed down, pressure is generated, causing the connecting plate 107 to drive the connecting telescopic rod 104 connected to the bottom block 106 to contract, and at the same time, the pressure spring 105 is also contracted, causing the connecting plate 107 to continue to move upward. When the connecting plate 107 moves, the inner wall of the auxiliary hole block 112 touches one end of the drill bit 102, and one end of the drill bit 102 presses against the inner wall of the auxiliary hole block 112, causing the auxiliary hole block 112 to be stretched from the inside out. When the hole-opening block 112 is pressed down, the pressure is vertically downward, so the auxiliary hole-opening block 112 will not expand. When the auxiliary hole-opening block 112 is subjected to pressure from the drill bit 102, it is from the inside out, so the auxiliary hole-opening block 112 will expand a small gap. As the drill bit 102 continues to move, the outer wall of the drill bit 102 will continue to expand the auxiliary hole-opening block 112. After the auxiliary hole-opening block 112 expands, it will drive the pressure telescopic rod 109 to contract, and the support spring 110 will also contract synchronously, thereby allowing the drill bit 102 to drill a hole in the mobile phone.
[0031] 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 characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
