Abstract
Description
Technical Field
[0001] This utility model relates to the field of hanging fixture technology, specifically to a general-purpose anodizing hanging fixture. Background Technology
[0002] Anodizing is an electrochemical oxidation process of metals or alloys. The metal or alloy parts are placed in a corresponding electrolyte as the anode, and electrolysis occurs under specific process conditions and the action of an applied current, eventually forming an oxide film layer on the surface of the parts.
[0003] In the anodizing process of parts, the anodizing rack is an indispensable tool. Its function is to fix the parts, connect the electrodes, and ensure that the current is evenly transmitted to the parts for anodizing. Therefore, the rational selection of anodizing racks is of great significance for ensuring the quality of the oxide layer, improving production efficiency, and reducing labor intensity.
[0004] Anodizing fixtures and clamps should have sufficient mechanical strength and rigidity to prevent the workpiece from being washed off by the rapid flow of solution when stirring the electrolyte. In addition, the fixtures should have good contact conductivity, be lightweight, sturdy and durable, easy to load and unload the workpiece, have a small contact area with the workpiece, but be able to ensure smooth current flow, and have appropriate requirements for load capacity and workpiece layout. There are two common types of hard anodizing fixtures: one is a clamp with clamping screws, and the other is a clamp or clamp connected by bolts, in which all contacts with the workpiece are made of aluminum alloy. However, these two types of fixtures have the following disadvantages: (1) Each fixture is designed according to the internal structure of the workpiece to be anodized, which has a limited scope of application and low utilization rate, resulting in waste; (2) The clamp or clamp connected by bolts has high processing precision requirements, which lengthens the production cycle; (3) Traditional fixtures can no longer meet the production needs of some workpieces with special structures.
