Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone accessories processing, in particular to a rotatable fixture. Background Art

[0002] As is known to all, the middle frame of a mobile phone is an important component of the mobile phone body. It is the outer shell structure around the mobile phone for protecting the mobile phone. The safety of the middle frame of the mobile phone is related to the safety of the entire mobile phone. Therefore, in order to improve the overall safety of the mobile phone, the middle frame of the mobile phone needs to be processed with side holes and sprayed during the production process of the mobile phone. In order to improve the processing efficiency, the middle frame of the mobile phone needs to be fixed by a clamp. The existing method is to clamp and fix it by a clamp. Due to different processing methods, the clamps for side hole processing and spraying are different. For example, the clamp used in the side hole processing process is disclosed in Publication No.: CN201621432519.8, which discloses an easy-to-use side milling positioning clamp, which is fixedly connected to the driving end of the driving mechanism by a fault-tolerant adjustment mechanism, an upper clamping block for directly abutting the middle frame of the mobile phone, and a connecting block fixedly connected thereto, which is indirectly connected to the driving end of the driving mechanism through a fault-tolerant adjustment mechanism, so that the upper clamping block can be accurately positioned relative to the lower clamping block, thereby improving the clamping and positioning effect of the middle frame of the mobile phone. When spraying is required, the fixture used is as shown in the publication number: CN202322185853.4, which discloses a mobile phone middle frame spraying fixture. The fixture is not only easy to clamp, but also can perform all-round spraying on the mobile phone middle frame by flipping the mobile phone middle frame over and rotating the mobile phone middle frame as a whole at the same time, avoiding the situation in which the existing spraying fixture often fixes the mobile phone middle frame in one position, making it difficult for the sprayer to spray it in all directions. Ultimately, it is beneficial to ensure that the coating on the mobile phone middle frame is sprayed more fully and evenly, greatly ensuring the spraying effect.

[0003] The above-mentioned fixture has the following problems: the existing fixture cannot meet the clamping requirements of the mobile phone middle frame for the spraying process and the side hole processing process at the same time, and the fixture needs to be replaced. This method increases the customization cost of the fixture, and requires the disassembly of the workpiece material and subsequent repositioning and correction, which affects the processing efficiency and cannot meet the needs of existing mobile phone production.
