Technical Field

[0001] This utility model relates to the field of mobile phone accessory processing technology, and in particular to a high-precision mobile phone accessory processing device. Background Technology

[0002] As a portable communication device, mobile phones can perform various communication functions such as voice calls, text messaging, and data transmission while on the move. During the production process of mobile phones, holes need to be drilled in the phone casing to install various functional components (such as cameras, speakers, microphones, buttons, etc.). With the rapid development of technology, the requirements for mobile phone production are becoming increasingly stringent. The precision and stability of the drilling process directly affect the quality and performance of the product. Misalignment and skewness during the drilling process are common problems, which can not only affect the installation accuracy of components, but also lead to damage to the casing, increase the defect rate, and even affect the overall quality of the mobile phone.

[0003] Therefore, this utility model proposes a high-precision mobile phone accessory processing device. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision mobile phone accessory processing device to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision mobile phone accessory processing device includes a gear 1, a rack 2 meshing with the outer wall of the gear 1, two sets of rack 1 attached to the top of the rack 2, the opposite sides of the two sets of rack 1 meshing with the two sides of the gear 1, one set of rack 1 having a set of side clamps fixedly connected to the top of one set of rack 1, and a connecting block fixedly connected to the front of the other set of rack 1, the top of the connecting block being fixedly connected to the bottom of the other set of side clamps.

[0007] Furthermore, the top of the base plate is provided with a movable groove, and two sets of side clamps are slidably sleeved inside the movable groove, with the two sets of side clamps located on both sides of the movable groove.

[0008] Furthermore, the fixing mechanism includes a fitting push block, the inner wall of which has four sets of circular holes, and each of the circular holes is movably fitted with a stop block. Each stop block has a connecting rod fixedly connected to its front side, the front side of which is fixedly connected to the front baffle. A rotating push block is fitted to the front side of the front baffle, and the back side of the rotating push block is fitted to the fitting push block.

[0009] Furthermore, one end of a spring is fixedly connected to the front of the stop block, the other end of the spring is fixedly connected to the inner wall of the push block, and the inside of the spring is movably sleeved with the connecting rod.

[0010] Furthermore, a connecting rod is fixedly sleeved inside the rotating push block, a handle is fixedly connected to the top end of the connecting rod, and a second gear is fixedly connected to the bottom end of the connecting rod. The outer wall of the second gear meshes with the second rack.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By rotating the handle to make the rotating push block vertical, push the bonding push block to move to the rear side, so that the bonding push block and the back baffle clamp and fix the mobile phone shell, so that the mobile phone shell remains stable when drilling. Stable clamping can prevent the workpiece from cracking or breaking due to vibration or shaking during the drilling process, especially when processing thin or brittle mobile phone shell materials, and also helps to reduce burrs generated during the drilling process and improve the surface quality of the hole.

[0013] 2. By rotating the handle, the rotating push block drives the second gear to rotate, which in turn meshes with the second rack, causing the second rack to rotate synchronously with the first gear. The first gear rotates synchronously, and further, through the meshing racks on both sides, it drives the side clamping plates to move inward, so that the phone shell is fixed in a centered position. The phone shell is fixed in the same position each time. The same knob mechanism controls the centering and fixing at the same time, which can ensure that the phone shell always maintains a precise center position during the processing, reducing the cumulative error caused by step-by-step adjustments and ensuring the accuracy of the drilling position.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 As shown, the high-precision mobile phone accessory processing device provided by this utility model includes a base plate 1, a column 2 fixedly connected to the top of the base plate 1, an electric telescopic machine 3 fixedly connected inside the column 2, a drill bit 4 fixedly connected to the bottom of the electric telescopic machine 3, a central structure provided at the lower end of the drill bit 4, and a rear baffle 6 attached to the back of the central structure, with the bottom end of the rear baffle 6 fixedly connected to the base plate 1.

[0022] A front baffle 5 is fixedly connected to the front of the base plate 1, and a fixing mechanism is fixedly connected to the back of the front baffle 5. The bottom end of the fixing mechanism meshes with one end of the rack 18, and the other end of the rack 18 meshes with the central structure.

[0023] The central structure includes a gear 17, with a rack 18 meshing on the outer wall of the gear 17. Two sets of racks 16 are attached to the top of the rack 18. The opposite sides of the two sets of racks 16 mesh with the two sides of the gear 17. One set of racks 16 is fixedly connected to the top of one set of side clamps 7, and a connecting block 15 is fixedly connected to the front of the other set of racks 16. The top of the connecting block 15 is fixedly connected to the bottom of the other set of side clamps 7.

[0024] The top of the base plate 1 is provided with a movable groove, and two sets of side clamps 7 are slidably sleeved inside the movable groove, with the two sets of side clamps 7 located on both sides of the movable groove.

[0025] During the mobile phone manufacturing process, holes need to be made on the sides of the phone casing to house components such as the handset and speaker. When holes need to be made, the worker places the phone casing at the front end of the back panel 6, so that the phone casing is on the opposite side of the back panel 6 and the bonding push block 11. Before drilling, the handle 8 is pulled, causing the handle 8 to rotate around the connecting rod 9 as the center, so that the handle 8 rotates from a horizontal position to a vertical position. The rotating connecting rod 9 simultaneously drives the rotating push block 10 to rotate, and the rotating push block 10 rotates from a horizontal position to a vertical position, thereby pushing the bonding push block 11 to move to the rear side, so that the back of the bonding push block 11 is in contact with the phone casing. At this time, the bonding push block 11 and the back panel 6 clamp the phone casing, keeping the phone casing stable during drilling. The workpiece shaking will cause the drill bit to deviate, thus ensuring that the diameter of the drilled hole meets the tolerance requirements.

[0026] Furthermore, while the bonding push block 11 moves, it slides on the surface of the connecting rod 14 to maintain stability during movement. When drilling is completed, the rotating push block 10 returns to the horizontal state. Under the influence of the elastic potential energy of the spring 13, it pushes the bonding push block 11 to move forward, thereby canceling the clamping of the bonding push block 11 on the mobile phone shell, which facilitates the removal of the part after drilling and improves production efficiency.

[0027] Example 2

[0028] Based on Example 1, please refer to Figures 1 to 4 As shown, the fixing mechanism includes a fitting push block 11. The inner wall of the fitting push block 11 has four sets of round holes, and each round hole is movably fitted with a stop block 12. The front of each stop block 12 is fixedly connected to a connecting rod 14. The front of the connecting rod 14 is fixedly connected to the front baffle 5. The front of the front baffle 5 is fitted with a rotating push block 10, and the back of the rotating push block 10 is fitted with the fitting push block 11.

[0029] One end of a spring 13 is fixedly connected to the front of the stop block 12, and the other end of the spring 13 is fixedly connected to the inner wall of the push block 11. The inside of the spring 13 is movably connected to the connecting rod 14.

[0030] The rotating push block 10 is internally fixedly fitted with a connecting rod 9. The top end of the connecting rod 9 is fixedly connected with a handle 8, and the bottom end of the connecting rod 9 is fixedly connected with a gear 19. The outer wall of the gear 19 meshes with the rack 18.

[0031] When the handle 8 is in a vertical position, the connecting rod 9 synchronously drives the gear 19 to rotate inside the base plate 1. The gear 19 meshes with the rack 18, pushing the rack 18 to move backward, so that the outer wall of the rack 18 meshes with the gear 17, causing the gear 17 to rotate synchronously. While the gear 17 rotates, it drives the racks 16 on both sides to mesh with it. One set of racks 16 drives the side clamping plate 7 to move towards the center, and the other set of racks 16 drives the other set of side clamping plates 7 to move towards the center through the connecting block 15. This allows the two sets of side clamping plates 7 to clamp the phone shell in the center, keeping the phone shell in the center position and maintaining the accuracy during drilling. Centering and fixing are achieved through a fixed knob, ensuring that the same position is maintained each time.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
