Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixing fixture for the production and processing of mobile phone back cover plates. Background Technology

[0002] The back cover of a mobile phone is an important component of the smartphone body. Together with the mid-frame and front frame, it forms the main structure of the phone, providing physical support for internal components such as the battery, camera, and wireless module, and protecting it from external impacts and scratches. The manufacturing process of the back cover involves processes such as grinding, drilling, painting, and grooving to optimize its appearance, performance, and compatibility. In this process, the fixing fixtures used for processing the mobile phone back cover are key pieces of equipment.

[0003] In the manufacturing and processing of mobile phone back covers, processes such as precision grinding, drilling, and surface coating all place stringent requirements on the fixed positioning of the back cover. Stable and precise fixing is the key foundation for ensuring the processing accuracy, consistency, and surface quality of the back cover. However, existing mobile phone back cover processing fixtures have significant defects: some traditional fixtures have poor structural design, making it difficult to ensure precise positioning of the back cover during fixing, and displacement or shaking is prone to occur during processing, resulting in decreased processing accuracy and increased product defect rate; other fixtures, although they have a certain fixing capacity, have complex structures and are cumbersome to operate, which not only increases the complexity of the production process but also drives up production costs, hindering large-scale and efficient production.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for the production and processing of mobile phone back cover panels, comprising a base plate, a bottom plate, and a face frame;

[0007] The base plate is disposed on the base plate, and a workpiece placement stage is disposed on the base plate;

[0008] The face frame is placed on the base plate and surrounds the edge of the workpiece;

[0009] The four sides of the inner side of the face frame are provided with contour blocks. The inner edge of the contour blocks is consistent with the edge of the workpiece. During the process of the face frame being placed on the base plate, the contour blocks provided on the inner side of the face frame fit against the edge of the workpiece, thus limiting the workpiece.

[0010] The side of the face frame is provided with an elastic element that acts on the contour block. The elastic element generates a force that pushes the contour block close to the edge of the workpiece, so that multiple contour blocks cooperate with each other to clamp the workpiece.

[0011] As a further embodiment of this utility model: a fixing rod is provided at each of the four corners of the upper end of the base plate, and a circular soft rubber ball is provided at the upper end of the fixing rod. A fixing hole is provided at each of the four corners of the lower end of the face frame. The fixing hole consists of a cylindrical part that matches the fixing rod and a circular cavity that matches the soft rubber ball, from top to bottom.

[0012] As a further embodiment of this utility model: the inner side of the face frame is provided with an movable notch corresponding to the contour block, the end of the contour block facing the face frame is connected to a guide rod, the face frame is provided with a guide hole corresponding to the guide rod, and the guide rod passes through the guide hole and is connected to a top piece;

[0013] The elastic element is disposed between the top plate and the side end of the face frame.

[0014] As a further embodiment of this utility model: the elastic element is a spring, and the elastic element is sleeved on the guide rod.

[0015] As a further embodiment of this utility model: a positioning post is provided at the upper end of the base plate, and a positioning hole corresponding to the positioning post is provided on the face frame, and the positioning post and the positioning hole are interlocked.

[0016] As a further embodiment of this utility model: grip plates are provided on both sides of the face frame.

[0017] As a further embodiment of this utility model: a fixing bolt is provided on the base plate, and the fixing bolt is fixedly connected to the screw hole reserved on the base plate.

[0018] Compared with the prior art, the beneficial effects of this technical solution are as follows: In use, the back cover of the mobile phone is first pre-positioned by the workpiece placement stage on the base plate, and then the face frame is placed on the base plate and the workpiece. During this process, the contour block will contact the edge of the workpiece and move in the opposite direction to the workpiece as it gradually moves down, squeezing the elastic element. When the face frame is completely placed on the base plate and the workpiece, the inner arc surface of the contour block fits with the edge of the workpiece. The push of the contour block by the elastic element makes multiple contour blocks fit tightly with the arc edge of the workpiece and form a clamping force, thereby providing stable and precise fixation for the workpiece, ensuring the processing accuracy of the workpiece. At the same time, the workpiece fixing operation is simple and fast, which simplifies the production process, so as to improve processing accuracy while improving processing efficiency and reducing production costs.

[0019] When the face frame is placed on the base plate, the soft rubber ball on the fixing rod is squeezed against the cylindrical part of the fixing hole, causing the soft rubber ball to deform and shrink in volume. Then, as the face frame moves down, it enters the circular cavity and restores its original shape inside the circular cavity. Through the soft rubber ball and the circular cavity, the face frame is fixed on the base plate, preventing the face frame from shifting during the workpiece processing and affecting the processing accuracy.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] 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.

[0032] Please see Figure 1-7 A fixing fixture for manufacturing and processing a mobile phone back cover includes a base plate 1, a bottom plate 2, and a face frame 3.

[0033] The base plate 2 is disposed on the base plate 1, and a workpiece placement stage 21 is disposed on the base plate 2;

[0034] The face frame 3 is placed on the base plate 2 and surrounds the edge of the workpiece;

[0035] The four sides of the inner side of the face frame 3 are provided with contour blocks 4. The inner edge of the contour blocks 4 is consistent with the edge of the workpiece. During the process of the face frame 3 covering the base plate 2, the contour blocks 4 provided on the inner side of the face frame 3 fit with the edge of the workpiece, forming a limit on the workpiece.

[0036] The side end of the face frame 3 is provided with an elastic element 5 that acts on the contour block 4. The elastic element 5 generates a force that pushes the contour block 4 close to the edge of the workpiece, so that multiple contour blocks 4 cooperate with each other to clamp the workpiece.

[0037] Specifically, in use, the back cover of the mobile phone (hereinafter referred to as "workpiece") is first pre-positioned by the workpiece placement stage 21 on the base plate 2. The overall shape of the workpiece placement stage 21 matches the internal shape of the workpiece. Then, the face frame 3 is placed on the base plate 2 and the workpiece. During this process, the contour block 4 on the inner side of the face frame 3 will contact the edge of the workpiece. As it gradually moves down, the contour block 4 gradually moves in the opposite direction to the workpiece, and then squeezes the elastic element 5. When the face frame 3 is completely placed on the base plate 2 and the workpiece, the inner edge of the contour block 4 will fit with the edge of the workpiece. That is, the contour block 4 has an arc surface that matches the edge of the workpiece. By using the elastic element 5 to push the contour block 4, multiple contour blocks 4 fit tightly with the arc edge of the workpiece and form a clamping force, thereby providing stable and precise fixation for the workpiece, ensuring the processing accuracy of the workpiece. At the same time, the workpiece fixing operation is simple and fast, which simplifies the production process, so as to improve processing accuracy while improving processing efficiency and reducing production costs.

[0038] Preferably, multiple contour blocks 4 are provided, such as Figure 5As shown, there are four contour blocks 4 distributed on the inner side of the face frame 3. For example, two contour blocks 4 are set on each of the two sides in the length direction, and one contour block 4 is set on each of the two sides in the width direction. This provides all-round positioning and fixing of the workpiece in the middle, ensuring that the workpiece remains stable during processing.

[0039] In some embodiments, the inner side of the face frame 3 is provided with an movable notch 31 corresponding to the contour block 4, the contour block 4 is connected to a guide rod 6 on one side facing the face frame 3, the face frame 3 is provided with a guide hole corresponding to the guide rod 6, the guide rod 6 passes through the guide hole and is connected to a top piece 61.

[0040] The elastic element 5 is located between the top piece 61 and the side end of the face frame 3.

[0041] Specifically, a movable notch 31 is provided on the face frame 3 to accommodate the contour block 4, so that the inner sidewall of the face frame 3 remains flat. By using the interlocking cooperation between the guide rod 6 and the guide hole on the face frame, and by placing the elastic element 5 between the top piece 61 of the guide rod 6 and the face frame 3, the parallel position of the contour block 4 can remain unchanged when it is displaced, thereby ensuring that the arc surface of the contour block 4 can fit with the edge of the workpiece.

[0042] Preferably, the elastic element 5 is a spring, and the elastic element 5 is sleeved on the guide rod 6, so that the thrust of the elastic element 5 is more concentrated and stable.

[0043] In some embodiments, a fixing rod 7 is provided at each of the four corners of the upper end of the base plate 2, and a circular soft rubber ball 8 is provided at the upper end of the fixing rod 7. A fixing hole 32 is provided at each of the four corners of the lower end of the face frame 3. The fixing hole 32 consists of a cylindrical part 321 that matches the fixing rod 7 and a circular cavity 322 that matches the soft rubber ball 8, from top to bottom.

[0044] Specifically, when the face frame 3 is placed on the base plate 2, the soft rubber ball 8 on the fixing rod 7 is squeezed against the cylindrical part 321 of the fixing hole 32, causing the soft rubber ball 8 to deform and shrink in volume. Then, as the face frame 3 moves down, it enters the circular cavity 322 and restores its original shape inside the circular cavity 322. Through the soft rubber ball 8 and the circular cavity 322, the face frame 3 is fixed on the base plate 2, preventing the face frame 3 from shifting during the workpiece processing and affecting the processing accuracy.

[0045] After the workpiece is processed, by lifting the face frame 3 upward, the connection between the cylindrical part 321 and the circular cavity 322 is squeezed to compress the soft rubber ball 8, causing the soft rubber ball 8 to deform and disengage from the fixing hole 32 through the cylindrical part 321, thereby allowing the face frame 3 to be removed from the base plate 2, and then the workpiece placed on the workpiece table 21 can be removed.

[0046] In some embodiments, a positioning post 9 is provided on the upper end of the base plate 2, and a positioning hole 33 corresponding to the positioning post 9 is provided on the face frame 3, and the positioning post 9 and the positioning hole 33 are inserted into each other.

[0047] Specifically, during the process of covering the face frame 3 onto the base plate 2, the face frame 3 can be positioned by setting the positioning post 9 and the positioning hole 33, thereby allowing the soft rubber ball 8 on the fixing rod 7 to stably enter the circular cavity 322.

[0048] In some embodiments, grips 10 are provided on both sides of the faceplate 3, which help staff to easily pick up the faceplate 3.

[0049] In some embodiments, a fixing bolt 11 is provided on the base plate 2, and the fixing bolt 11 is fixedly connected to the screw hole reserved on the base plate 1. In this application, the base plate 1 can be installed on the processing equipment. After the workpiece is placed on the workpiece placement table 21 and fixed with the face frame 3, processing can be performed. When it is necessary to process different types of workpieces, the base plate 2 can be removed from the base plate 1 by unscrewing the fixing bolt 11, and then the corresponding base plate 2 can be replaced.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
