Mobile phone middle frame polishing clamp and milling machine thereof

Abstract

A mobile phone middle frame polishing clamp comprises a supporting base and a positioning module. The positioning module is installed on the supporting base and comprises a plurality of positioning assemblies; the positioning assemblies are sequentially stacked; each positioning assembly comprises a layer connection board, a middle frame positioning part, a middle frame liner part and a splicing column, wherein the splicing column is arranged on the layer connection board and penetrates through the middle frame positioning part, and an insertion-connection groove is formed in the side face, away from the splicing column, of the layer connection board; and the splicing column of each positioning assembly is also in inserted connection with the insertion-connection groove of the layer connection board of the adjacent positioning assembly. The mobile phone middle frame polishing clamp is provided with the supporting base and the positioning module, so that a mobile phone middle frame is positioned through the positioning module, multiple mobile phone middle frames are clamped at the same time, the polishing efficiency of the mobile phone middle frames is improved, the positioning module is convenient to dismount, the number of the mobile phone middle frames clamped each time can be adjusted flexibly, and the clamping efficiency of the mobile phone middle frames is improved.

Description

technical field [0001] The invention relates to the field of automatic processing, in particular to a polishing jig for a middle frame of a mobile phone and a grinding machine thereof. Background technique [0002] The middle frame of the mobile phone, that is, the frame of the mobile phone, is used to support the entire mobile phone. The quality of the mobile phone depends largely on whether the middle frame of the mobile phone is well done. Therefore, the production and processing of the middle frame of the mobile phone needs to go through many steps, such as CNC Processing, drilling, polishing, etc. Polishing is the surface treatment of the middle frame of the mobile phone, removing the burrs on the surface of the middle frame of the mobile phone during the processing, so that the surface of the middle frame of the mobile phone is smooth. [0003] However, since the surface of the middle frame of the mobile phone has a certain radian, in order to ensure the accuracy of th...

Problems solved by technology

[0003] However, since the surface of the middle frame of the mobile phone has a certain radian, in order to ensure the accuracy of the polishing of the middle frame of the mobile phone, it is necessary to clamp and position the middle frame of the mobile phone one by one, and then perform grinding processing, and in order to avoid the radian on the middle frame of the mobile phone Missing machining occurs on the surface, and it is necessary to clamp the middle frame of the mobile phone multiple times to change the angle of the middle frame of the mobile phone relative to the polishing knife to ensure the quality of polishing, but this will face the problem of low processing efficiency

[0004] like Figure 5 The middle frame 20 of the mobile phone shown includes a panel 21 for installing electronic components and a frame 22 arranged around the panel 21. Before assembly, the frame 22 needs to be polished, and the polishing operation needs to go through four stations, respectively Grinding different parts of the frame 22, and the surface of the frame 22 has a certain radian, it is necessary to leave enough space for the polishing wheel to enter when clamping, which increases the difficulty of polishing the middle frame 20 of the mobile phone, which is not conducive to Multiple mobile phone middle frames 20 are clamped at the same time, which limits the efficiency of polishing the mobile phone middle frame 20
