Abstract

The invention relates to a positioning device which comprises a box body, a lifting plate arranged in the box body and a sliding block slidably arranged in the box body. A plurality of through holes are formed in the box body. Pins penetrating through the through holes are arranged on a first surface of the lifting plate in a protruding mode. A linkage block is arranged on a second surface of the lifting plate in a protruding mode. Guide columns and elastic pieces used for being connected with the lifting plate are arranged in the box body. The lifting plate is slidably arranged along the guide columns. Oblique faces which slide in a matched mode are arranged on the sliding block and the linkage block respectively. According to the positioning device, the oblique faces which slide in the matched mode are arranged on the sliding block and the linkage block respectively, so that when the sliding block moves towards the linkage block, the lifting plate is driven to overcome the resistance of the elastic pieces so that the pins can be driven to retract towards the interior of the box body, a mobile phone middle frame positioned on the box body can be separated from the pins through the pins, the mobile phone middle frame can be taken away easily, and the situation that the positioning accuracy of the mobile phone middle frame is affected due to the fact that the mobile phone middle frame and the pins are matched loosely is avoided.

Description

technical field

[0001] The invention relates to the technical field of processing middle frames of mobile phone accessories, in particular to a positioning device for processing middle frames of mobile phones. Background technique

[0002] In the manufacturing process of the middle frame of the mobile phone, it is usually necessary to position the middle frame of the mobile phone on the jig for drilling, milling, assembly and other operations. At present, pins are generally used to position the middle frame of the mobile phone. However, when the middle frame of the mobile phone is removed from the jig, it is often difficult to remove the middle frame of the mobile phone because the middle frame of the mobile phone is too tightly matched with the pins. It cannot be ignored that when the middle frame of the mobile phone fits too loosely with the pins, the positioning accuracy of the middle frame of the mobile phone will be affected, which will have a negative impact on subsequ...
