Electroplating fixture for inverter cooling fins

Abstract

The invention belongs to the technical field of electrical equipment, and particularly relates to an electroplating fixture for inverter cooling fins. The electroplating fixture for the inverter cooling fins comprises a support and a plurality of clamps, a main air pipe and a connecting wire are arranged on the support, a plurality of connecting frames are fixedly connected to the support, the clamps are fixedly connected with the support through the connecting frames, fixing mechanisms are arranged on the clamps, and each clamp comprises a fixing box and a sealing mechanism. Air is deliveredinto main air bags through an external air sources, the main air bags and branch air bags are full of the air, the branch air bags are expanded, the size is increased, the branch air bags make close contact with the cooling tooth walls of the cooling fins, the cooling tooth walls of the cooling fins are sealed, the whole installing process is simple, few installing steps are needed, and meanwhileit is guaranteed that the cooling tooth walls of the cooling fins are sealed; and the fixing mechanisms are adjusted to compress and fix the cooling fins, the disassembling process is easy to operate,few disassembling steps are needed, the workpiece assembling and disassembling time can be significantly shortened, and the electroplating efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an electroplating jig for inverter cooling fins. Background technique [0002] The inverter converts DC power (battery, storage battery) into AC power. It consists of an inverter bridge, control logic and filter circuit. The inverter is a DCtoAC transformer. It is actually a voltage inverter with the converter. Generally speaking, an inverter is a device that converts direct current (DC) into alternating current (AC). The converter is to convert the AC voltage of the power grid into a stable 12V DC output. In the prior art, rack plating is used to carry out silver plating on the surface of the heat dissipation template and the inverter, that is, the electroplating surface, so as to improve the heat dissipation. On the plated surface of the template, a coating film that is both oxidation-resistant and corrosion-resistant is formed, thereby greatly improvi...
