Four-sided milling fixture

Abstract

The invention discloses a four-side hole-milling fixture, which is used for milling holes at four side faces of a mobile phone middle frame, and comprises a fixedly arranged hole-milling lower fixture and a hole-milling upper fixture capable of moving up-and-down relative to the hole-milling lower fixture. A plurality of limited blocks for pressing against the lower side face of the mobile phone middle frame are arranged on the upper side of the hole-milling lower fixture; a limited bump for pressing against the upper side face of the mobile phone middle frame is arranged on the lower side of the hole-milling upper fixture; and the limited blocks and the limited bump press against the upper side and the lower side of the mobile phone middle frame, so that the four side faces of the mobile phone middle frame are exposed. According to the four-side hole-milling fixture provided by the invention, the mobile phone middle frame is clamped and positioned through opening and closing of the fixedly arranged hole-milling lower fixture and the hole-milling upper fixture capable of moving up-and-down relative to the hole-milling lower fixture, and the upper side and the lower side of the mobile phone middle frame are clamped and positioned through the bulged limited bump and the bulged limited blocks, so that the four side faces of the mobile phone middle frame are exposed, and can be conveniently subjected to hole-milling.

Description

technical field [0001] The invention relates to a jig for producing a mobile phone, in particular to a jig for clamping a middle frame of a mobile phone. Background technique [0002] As the main frame structure of the mobile phone, the middle frame of the mobile phone needs to accommodate and position various electrical components, and the edge side of the middle frame of the mobile phone needs to be provided with multiple avoidance holes, such as power interface, earphone interface, volume key avoidance holes, and power button avoidance holes , SIM card positioning block insertion holes, etc., so as to realize the operation and connection between multiple electrical components arranged in the middle frame of the mobile phone and the outside. [0003] The multiple avoidance holes opened on the four sides of the middle frame of the mobile phone need to cooperate with internal and / or external electrical components, and their dimensional accuracy requires high precision. The m...

AI Technical Summary

Problems solved by technology

The middle frame of the mobile phone needs to accommodate and position various electrical components. Therefore, the shape of the inner wall of the middle frame of the mobile phone is relatively complex and precise, so it is difficult to locate the middle frame of the mobile phone, and the existing positioning fixture is not enough to meet the use requirements.
