Electrophoretic multifunctional clamp for an automobile three-guarantee part

Abstract

The invention discloses an electrophoretic multifunctional clamp for an automobile three-guarantee part. The electrophoretic multifunctional clamp comprises a sling stand column matched with an electrophoretic sling. The sling stand column and the electrophoretic sling are connected in a fixed manner and form a cathode power supply circuit. The sling stand column is provided with a plurality of hook pin sleeves matched with the position of a fabrication hole of the three-guarantee part and with the center of gravity of the three-guarantee part. The hook pin sleeves are perpendicular to the sling stand column and are disposed horizontally. The hook pin sleeves are provided with clamping surfaces and supporting surfaces. The clamping surfaces and the supporting surfaces respectively extend out of the two side surfaces of the sling stand column. Clip hooks are movably disposed in the hook pin sleeves in a pass through manner. Hook necks of the clip hooks pass through the hook pin sleeves and are rotatably connected with a clamping handle. Hook ends of the clip hooks are matched with the clamping surfaces, and move relative to the clamping surfaces in a clamping process. An end, which is closed to the supporting surfaces of the hook pin sleeves, of the clamping handle is provided with a rotary surface. The rotary surface is pressed on the supporting surfaces and rotates by using the supporting surfaces as a fulcrum. The clamp is simple in structure, convenient in operation, good in electrophoretic effect and uniform in electro coating film, and can effectively improve the electrophoretic quality of the three-guarantee part.

Description

technical field [0001] The invention relates to the technical field of electrophoresis in automobile manufacturing, in particular to a multifunctional electrophoresis fixture for three-package parts of automobiles. Background technique [0002] From the launch of each car to its scrapping, most of the parts that need to be replaced in the life cycle of more than ten years are equivalent to the amount of reproducing a car body, and a large number of parts are mostly electrophoresis rust-proof plates that are rusted and worn out, and most of them are electrophoresis rooms that were updated later. It shows that the poor electrophoresis of the three-package parts of the car brings technical defects and serious consequences. [0003] At present, the three-package parts of the car are electrophoresed in the car body or on the special spreader. The three-package parts are relatively fixed. Under the action of the flowing tank liquid, the three-package parts will move, float, turn o...

Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that the three-package parts of the automobile body are bound in the tank body with iron bars due to the backward suspension method in the electrophoresis process, and the three-package parts are not fixed firmly during the operation of the spreader and the tank liquid flows, resulting in floating movement Flipping and other phenomena lead to insufficient power supply, and the
