Falling and deformation preventing type negative-pressure profiling jig

Abstract

The invention discloses a falling and deformation preventing type negative-pressure profiling jig. The falling and deformation preventing type negative-pressure profiling jig comprises a jig seat, wherein the upper end of the jig seat is connected with a mobile phone shell profiling jig; a negative pressure area is formed in the front surface of the mobile phone shell profiling jig and positioned at a corresponding position on a battery bin; a plurality of negative pressure slots are formed at intervals in the negative pressure area. According to the falling and deformation preventing type negative-pressure profiling jig, the shapes of mobile phones are various, and the battery bins of all mobile phones are similar in shape and large in area, so that the mobile phone shell can be fixed through each battery bin area; in addition, air can be pumped out through a negative pressure port, and thus the mobile phone shell can be stably fixed to the mobile phone shell profiling jig through the negative pressure; negative pressure joint is arranged between two forks , so that the negative pressure joint can be prevented from being impacted while assembling and disassembling the mobile phone shell; with the adoption of the negative pressure slots, the air between the mobile phone shell and the mobile phone shell profiling jig can be pumped out to the maximum, so that the mobile phone shell can be firmly fixed. The falling and deformation preventing type negative-pressure profiling jig is applied to grinding of the mobile phone shell.

Description

technical field [0001] The invention relates to a profiling anti-falling and anti-deformation negative pressure fixture. Background technique [0002] The existing mobile phone shell grinding process is difficult to realize automatic grinding due to the changeable shape of the mobile phone. Therefore, the current mobile phone shells are all manually carried out, but the quality is difficult to be effectively controlled and the efficiency is low. During the grinding process, it is necessary to cool the mobile phone shell with cooling fluid and lubricating fluid. Since manual processing will be carried out in an open environment, hard impurities will enter the cooling fluid and lubricating fluid during processing, so that The coolant and lubricating fluid used in the mobile phone often cannot be used again, because hard impurities such as sand and metal particles will damage the surface of the mobile phone case, causing the mobile phone case to have a poor appearance and be sc...
