AI Technical Summary

Technical Problem

When processing the mid-frame of a mobile phone, multiple surfaces need to be clamped, which leads to a decrease in positioning accuracy and an increase in fixture costs. How can we ensure dimensional stability and reduce processing costs?

Method used

The fixture design combines vacuum adsorption and elastic elements. It uses a contour plate and vacuum suction to fix the product, connects to external equipment through an air connector, and uses quick clamps and cover plates for multi-faceted processing, reducing fixture change errors and improving stability.

Benefits of technology

This technology improves positioning accuracy in multi-faceted machining, reduces the number of fixtures, lowers machining costs, prevents product damage, and enhances the stability and economy of the fixtures.

Abstract

This utility model relates to the field of mobile phone case processing technology, and in particular to a fixture for processing mobile phone mid-frames, comprising: a placement component for fixing the product, the placement component being provided with an air connector for external connection, and the placement component being fixed to the placement component by vacuum suction; a clamping component for fixing the product on the placement component, the clamping component having an elastic element on the side near the product to prevent damage to the product, and two clamping components for fixing the clamping component, the two clamping components being symmetrical to each other, the two clamping components clamping the two sides of the clamping component respectively. This utility model allows for processing from multiple sides, thus reducing positioning errors caused by jig changes. The two symmetrical clamping components can better fix the cover plate, and the two-component design can effectively save jigs while providing a more stable fixation.
