AI Technical Summary

Technical Problem

Existing electrophoretic coating fixtures make it difficult for pigments and resins to be deposited in areas where the workpiece is covered by the fixture, resulting in omissions in the electrophoretic coating and affecting the quality of the workpiece.

Method used

A workpiece holder for electrophoretic coating is designed, which adopts an adjustable clamping unit and a drive mechanism. By switching the clamping unit, the workpiece can be coated at different positions. The clamping unit includes two clamping parts, which are synchronously adjusted by a lead screw and gear mechanism to ensure that all positions of the workpiece can be coated.

Benefits of technology

It achieves comprehensive electrophoretic coating of workpieces, improves coating quality, and features simple, time-saving, and labor-saving clamping operation with good switching effect.

Abstract

The utility model discloses a workpiece fixing frame for electrophoretic coating, which comprises a fixing frame body and a clamping assembly, the clamping assembly is arranged on the fixing frame body, the clamping assembly comprises two clamping units, each clamping unit comprises two groups of clamping parts, and the two groups of clamping parts of the same clamping unit can be movably adjusted along the direction close to each other or far away from each other. The clamp is used for clamping or releasing a workpiece; wherein the clamping parts of the two clamping units are used for clamping different positions of a workpiece respectively, and after the clamping part of one clamping unit clamps the workpiece, the clamping part of the other clamping unit can be separated from the workpiece. According to the workpiece fixing frame for electrophoretic coating, electrophoretic coating of workpieces is more comprehensive, and the quality of the workpieces after electrophoretic coating is better.
