Abstract
Description
Technical Field
[0001] This utility model belongs to the field of processing equipment technology, and specifically relates to a grinding device for processing mobile phone hinges. Background Technology
[0002] In the field of mobile phone component processing, the hinge is a core component that enables the folding and flipping functions of mobile phones. Its processing precision and surface quality directly affect the performance and lifespan of the mobile phone. As a key step in hinge processing, the polishing process requires fine treatment of the hinge surface to meet assembly accuracy and appearance requirements. Therefore, the development of efficient and adaptable polishing equipment is of great significance.
[0003] Currently, most grinding devices for mobile phone hinge processing adopt a traditional single-station structure, which uses a simple clamping mechanism to fix the hinge and works in conjunction with a fixed grinding component. Such devices usually rely on manual loading and unloading, and the grinding position adjustment requires manual operation, resulting in a low degree of automation; at the same time, their clamping structure specifications are fixed, making it difficult to adapt to the processing requirements of hinges of different sizes.
[0004] Traditional equipment has significant technical defects: First, the single-station design means that only one shaft can be polished at a time, which cannot achieve batch operation, resulting in low production efficiency and difficulty in meeting the needs of large-scale production; Second, the grinding components lack adjustment flexibility and cannot accurately adapt to shafts of different diameters and lengths, thus limiting the applicability of processing. Utility Model Content
[0005] To address the aforementioned problems, the purpose of this utility model is to provide a grinding device for processing mobile phone hinges.
[0006] The technical solution of this utility model is: a grinding device for processing mobile phone hinges, comprising:
[0007] support;
[0008] A rotating support assembly includes a rotating shaft disposed on the bracket, a rotating roller coaxially fixedly sleeved on the outer side of the rotating shaft, a plurality of grooves provided on the side of the rotating roller, and clamping members provided on both sides of each groove, the clamping members being used to clamp the rotating shaft;
[0009] The adjustment and polishing assembly includes a device box disposed at the top of the bracket, the bottom of the device box having an opening corresponding to the groove, and a polishing assembly for polishing the rotating shaft being disposed inside the device box.
[0010] Furthermore, the polishing assembly includes:
[0011] Adjustment rails are respectively arranged on both sides of the equipment box, and an adjustment block is slidably embedded in each adjustment rail;
[0012] An electric telescopic rod is provided on the inner side of each of the adjusting blocks;
[0013] An electric grinding wheel is provided, with the distal ends of the two electric telescopic rods fixedly connected to the center of the electric grinding wheel. The electric grinding wheel is used to grind the surface of the rotating shaft.
[0014] The clamping member located on the left side of the groove includes a left fixing rod fixedly disposed on the left side of the groove, a left clamping plate fixedly disposed at the distal end of the left fixing rod, and a left fixing hole disposed at the center of the inner side of the left clamping plate;
[0015] The clamping component located on the right side of the groove includes a right fixing rod fixedly disposed on the right side of the groove. The far end of the right fixing rod is provided with a threaded hole. An adjusting bolt is provided in the threaded hole. A right clamping plate is provided inside the adjusting bolt. A right fixing hole is provided at the center of the inner side of the right clamping plate. The two ends of the rotating shaft are respectively engaged between the left fixing hole and the right fixing hole.
[0016] Furthermore, the equipment box is provided with a transparent observation window on its side.
[0017] Furthermore, a collection tray is provided below the support.
[0018] Furthermore, a drive motor is provided on the side of the bracket, and the output shaft of the drive motor is coaxially and fixedly connected to the rotating shaft.
[0019] The working method of this utility model is as follows: The height of the electric grinding wheel is adjusted by adjusting the adjustment block. The rotating shaft to be ground is clamped between the clamping parts in the groove on either side of the rotating roller. Then, the drive motor drives the rotating roller to rotate, so that the rotating shaft rotates to the bottom of the equipment box and contacts the edge of the electric grinding wheel. The electric grinding wheel rotates to grind the surface of the rotating shaft. The grinding position is adjusted under the drive of the electric telescopic rod. After the rotating shaft is ground, the drive motor drives the rotating roller to continue rotating, so that the rotating shaft rotates to the other side of the rotating roller. The rotating shaft can then be removed. While the rotating shaft is being ground, the above steps are repeated to achieve the clamping and fixing of the unground rotating shaft and the disassembly of the ground rotating shaft.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. The rotating roller of this utility model is provided with multiple grooves on its side. During the grinding process, the rotating shaft can be ground on one side of the rotating roller while the unground rotating shaft is clamped and fixed and the ground rotating shaft is disassembled at the groove on the other side, so as to realize continuous production and greatly shorten the processing cycle.
[0022] 2. The adjustment track, adjustment block and electric telescopic rod in the grinding assembly of this utility model can be used to precisely adjust the height and position of the electric grinding wheel to meet the grinding needs of rotating shafts with different diameters and lengths.
[0023] 3. The clamping component of this utility model adopts a combination design of "left fixed rod + left clamping plate" and "right fixed rod + adjusting bolt + right clamping plate". The position of the right clamping plate can be flexibly adjusted by rotating the adjusting bolt, so that the two ends of the rotating shaft are engaged between the left and right fixed holes, ensuring that rotating shafts of different specifications can be firmly clamped.
