A method of processing the middle frame of mobile phone based on floating datum

Abstract

The invention discloses a method for machining a mobile phone middle frame based on a floating datum. The method includes the steps that the mobile phone middle frame is positioned by a jig, so that afirst positioning face on the jig and a first datum face, used for guaranteeing the first machining size, on the mobile phone middle frame are attached flatly; the position of the mobile phone middleframe is adjusted, a floating datum face on the floating datum and a second datum face, used for guaranteeing the second machining size, on the mobile phone middle frame are attached flatly, and halfof the floating datum face is exposed out of the second datum face; a to-be-machined product is clamped by a clamp; a Z direction coordinate value of the floating datum face is detected; the Z direction coordinate value of the floating datum face is compensated into a machining program of a corresponding machining face; and the machining program controls a cutter to machine to the surface of themobile phone middle frame. During batch production, due to one-time clamping, the tolerance requirement of different machining sizes of different datum faces existing in the machined product is stablyguaranteed, the yield is guaranteed, and the efficiency of batch production is improved.

Description

technical field [0001] The invention relates to the field of mobile phone parts processing, in particular to a method for processing a middle frame of a mobile phone based on a floating reference. Background technique [0002] When it is necessary to ensure the size requirements of multiple measurement references at the same time in the processing size, it is usually necessary to divide the processing into multiple processes, respectively use the respective measurement references to locate and then process the size, so as to directly ensure the size requirements. The processing of the middle frame 20 of the mobile phone is the For example figure 1 As shown in the partial cross-sectional schematic diagram of the middle frame 20 of the mobile phone, it is required in the drawings to ensure both dimension A and dimension B during machining, dimension A being the first machining dimension, and dimension B being the second machining dimension. Dimension A and dimension B are dif...
