Description

Technical Field

[0001] The utility model relates to the technical field of engraving assistance, in particular to a rotary precision engraving fixture for holes around the middle frame. Background Technique

[0002] The middle frame of a mobile phone is a key part of the structure of a smart phone. It usually refers to the side frame of the mobile phone, which plays a role in supporting and protecting internal components. The design and materials of the middle frame of the mobile phone have an important impact on the durability, appearance and feel of the entire device. With the continuous progress of the design of smart phones, the materials and designs of the middle frames of mobile phones are also constantly innovating to meet the market's requirements for thin, light, beautiful and high-performance mobile phones. During the production of the middle frame of the mobile phone, it is necessary to perform precision engraving on its frame to install components such as buttons, charging ports and headphone jacks in the later stage.

[0003] When performing precision engraving on the middle frame product, a fixture is required to fix the product to assist the engraving machine in engraving. Currently, traditional fixtures usually use side cylinders to drive and press to fix the middle frame product. However, this type of fixture has poor flexibility, and the middle frame needs to be engraved on multiple surfaces. Therefore, it is necessary for operators to repeatedly adjust the orientation of the product, resulting in low precision engraving efficiency. In addition, manual placement combined with side cylinder pressing is also prone to certain safety hazards. Therefore, in view of these problems, a rotary precision engraving fixture for holes around the middle frame that can assist in engraving is needed. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a rotary precision engraving fixture for holes around the middle frame, which solves the problems raised in the above background technique.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A rotary precision engraving fixture for holes around the middle frame includes a five-axis CNC turntable. A fixed plate is arranged at the driving end of the five-axis CNC turntable. One side of the fixed plate is installed with a connecting block through bolts. One end of the connecting block is provided with a replacement plate. An electromagnet is also arranged at the center of one side of the fixed plate. The surface of the replacement plate is provided with a profiling base adapted to the middle frame, and a profiling iron cover plate is arranged on the surface of the profiling base.

[0006] Optionally, adsorption ports for facilitating the adsorption of the electromagnet are opened on the surfaces of the replacement plate and the profiling base.

[0007] Optionally, engraving grooves for facilitating side precision engraving are opened in the circumferential direction of the profiling base.

[0008] Optionally, placement marks for indicating the placement of the middle frame are arranged on the surface of the profiling iron cover plate.

[0009] Optionally, a handle block for taking is also arranged at the center of the surface of the profiling iron cover plate.

[0010] Optionally, mounting blocks are arranged on both sides of the five-axis CNC turntable, and mounting holes are formed on the surfaces of the mounting blocks.
