Description
Technical Field
The invention belongs to the technical field of electrolytic machining, and particularly relates to a chamfering electrolytic machining clamp for a mobile phone lens bracket group and a process method thereof.
Background
Chamfering refers to machining the edges of a part into inclined planes with a certain angle. For a mobile phone lens holder, chamfering is an important process in the processing technology. First, chamfering can remove burrs generated in machining, improving the surface quality of the workpiece. Secondly, the chamfer can improve the safety level in the production process. In the production process, untreated sharp edges and burrs threaten the personal safety of workers who carry out operations such as transportation, assembly, disassembly and the like. In addition, chamfering is carried out on the mobile phone lens bracket, so that the attractiveness of the mobile phone lens and the whole mobile phone is greatly improved, and the problem of user loss caused by poor modeling performance is avoided.
At present, common chamfering processing technologies mainly include turning, drilling (spot facing chamfering), bench worker, chamfering machine processing, numerical milling, electric spark processing, electrolytic machining and the like. The machining method is long in time consumption, low in efficiency, residual stress and burr generation risk, and has certain requirements on the technical level of an operator. The surface of a workpiece processed by the electric spark processing method can generate a recast layer, and the surface quality of the part is influenced.
The electrochemical machining is a machining technology for removing materials (electrochemical anode dissolution) based on the principle of electrochemical action, does not have mechanical cutting force, has high machining efficiency and no tool loss, and can be used for a long time. In addition, the material is removed in the form of ions in the electrolytic machining, the cold-state machining is adopted, the surface quality better than that of the traditional machining and the electric spark machining can be obtained, and the surface defects such as residual stress, recast layers and the like are avoided. Therefore, the electrolytic machining has a good application prospect in batch chamfering of the mobile phone lens brackets.
Due to the particularity of the electrolytic machining process, insulation treatment needs to be carried out on the non-machined part of the mobile phone lens bracket, and in addition, the mobile phone lens bracket is small in size and irregular in shape, so that the tool for machining the mobile phone lens bracket is more complex than that for machining the mobile phone lens bracket in the prior art. The mobile phone lens bracket has large market demand, is a product produced in large batch, and has higher requirements on processing speed and reloading speed. The conventional electrolytic machining clamp usually adopts a screw connection mode to clamp a workpiece, and the fixing mode is long in time consumption for replacing the workpiece and large in labor amount of workers, so that the chamfering machining requirement of large-batch and high-efficiency mobile phone lens brackets cannot be met. Therefore, a set of chamfering electrolytic machining clamp for the mobile phone lens bracket needs to be designed, wherein the replacing time is short, and the number of workpieces machined at one time is flexible.
