Mobile phone lens bracket group chamfer electrolytic machining fixture and technology method thereof

Abstract

The invention discloses a mobile phone lens bracket group chamfer electrolytic machining fixture and a technology method thereof. The fixture comprises a backpressure housing, a workpiece positioningblock and a cathode assembly; the workpiece positioning block comprises a positioning block body and a plurality of fixing assemblies, the positioning block body is detachably fixed into the backpressure housing, and a mobile phone lens bracket is fixed to each fixing assembly; the cathode assembly is located on the upper portion of the backpressure housing, and after the cathode assembly moves downwards, the lower end of the cathode assembly can stretch into the backpressure housing; the cathode assembly comprises a cathode and a cathode insulating cover; the cathode is provided with a plurality of machining channels, one ends of the machining channels are machining end openings arranged on the bottom surfaces, and each machining channel is provided with an annular machining insulating cover; bevels of the machining end opening are located between cathode insulating cover machining holes and bevels of machining insulating cover lower end openings, and machining blades are formed; andan electrolyte is injected into the machining channels, the cathode assembly is fed downwards, and the machining blades conduct chamfer machining on the edge of the corresponding mobile phone lens bracket. The mobile phone lens bracket group chamfer electrolytic machining fixture has the advantages of being efficient and convenient.

Description

technical field [0001] The invention belongs to the technical field of electrolytic machining, and in particular relates to an electrolytic machining jig and a process method thereof for chamfering the group of mobile phone lens brackets. Background technique [0002] Chamfering refers to the processing of cutting the corners of a part into a slope with a certain angle. For mobile phone lens brackets, chamfering is an important process in its processing technology. First of all, chamfering can remove burrs generated during processing and improve the surface quality of the workpiece. Second, chamfering can increase the level of safety during production. During the production process, untreated sharp edges and burrs pose a threat to the personal safety of workers performing operations such as transportation, assembly, and disassembly. In addition, the chamfering of the mobile phone lens bracket greatly improves the aesthetics of the mobile phone lens and the whole machine, ...

AI Technical Summary

Problems solved by technology

In the past, the electrolytic machining fixture often used screw connection to clamp the workpiece. This fixing method takes a long time to replace the workpiece, and the labor load of the workers is large. It cannot meet the requirements of large-scale and high-efficiency chamfering of mobile phone lens brackets.
