Suction cup type micro-arc oxidation clamp

Abstract

The invention discloses a suction cup type micro-arc oxidation clamp. The suction cup type micro-arc oxidation clamp is composed of a conductive nut 1, a sealing washer 2, a PVC pipe 3, a conductive spring 4, an electrode 5 and a suction cup 6, wherein the two ends of the PVC pipe 3 are connected to the conductive nut 1 and the suction cup 6 through threads respectively, the conductive spring 4 and the electrode 5 are arranged inside the PVC pipe 3, the conductive nut 1 is located at the upper part of the PVC pipe 3, and the sealing washer 2 is located between the conductive nut and the PVC pipe; the conductive nut is composed of a nut body and a copper column, and the copper column penetrates through the center of the nut body and is fixed; the copper column of the conductive nut 1 is located above the conductive spring 4, the T-shaped electrode 5 is located below the conductive spring 4, the diameter of the upper part of the electrode is equal to the outer diameter of the conductive spring, and the work end at the lower part of the electrode penetrates through a center hole of the suction cup; the suction cup 6 is located at the lower part of the PVC pipe 3, and a hole with the diameter equal to the diameter of the work end of the T-shaped electrode is formed in the center of the suction cup 6. The suction cup type micro-arc oxidation clamp is simple in structure, low in manufacturing cost, high in universality, reliable in performance, suitable for most work-pieces with planes and electrolytes different in acid-base property and wide in market prospect.

Description

technical field [0001] The invention relates to a micro-arc oxidation conductive fixture, which is suitable for micro-arc oxidation production of aluminum, magnesium, titanium and other micro-arc oxidizable metals and their alloy workpieces. Background technique [0002] The micro-arc oxidation process is simple, environmentally friendly, and the oxide ceramic film produced has excellent performance. The excellent insulation, corrosion resistance, wear resistance and high hardness of the ceramic film layer make related products widely used in industry, agriculture, military industry, aerospace, etc. with broadly application foreground. However, traditional clamping methods such as aluminum wire winding and titanium hangers have disadvantages such as difficult clamping, inaccurate calculation of total current, and even partial damage to the workpiece during the production process. The fixture needs to be cleaned in time after use, and the existence of these problems reduces ...
