AI Technical Summary

Technical Problem

It is difficult to achieve uniform paint film during the painting process of thin-walled rotary body parts. Due to factors such as light reflection, it is difficult for the existing technology to effectively spray paint from different perspectives, resulting in uneven spraying.

Method used

A gantry thin-walled slewing body parts painting auxiliary tooling is designed, including a rotating assembly and an inner support assembly. The 360° rotation of the part is achieved through the rotating assembly, and the paint is completed at the same viewing angle through the inner support assembly, eliminating the influence of human viewing angle differences.

Benefits of technology

The uniformity of the surface paint film of thin-walled rotary body parts is achieved, and the coating layer that meets the process requirements is simple in structure, convenient in operation, and protects the part port from spray painting.

Abstract

The utility model discloses a gantry type thin-wall revolving body part paint spraying auxiliary tool which comprises a portal frame and a suspension mechanism, the suspension mechanism comprises a rotating assembly and an inner supporting assembly, and the rotating assembly is arranged on the portal frame and used for driving a thin-wall revolving body part to rotate; and the inner supporting assembly is installed below the rotating assembly and configured to expand outwards or contract inwards, and in the using process, the inner supporting assembly is arranged in an inner cavity of the thin-wall rotary body part and expands outwards to support the side wall of the inner cavity of the thin-wall rotary body part so that the thin-wall rotary body part can be installed on the suspension mechanism. According to the auxiliary paint spraying tool for the thin-wall rotary body part, paint spraying of the part can be completed at the same visual angle by adjusting the rotating mechanism after a proper visual angle is selected during paint spraying of the thin-wall rotary body part, the influence of different visual angles of people on the paint spraying effect during paint spraying is eliminated, paint films on the surface of the part are uniform, and a coating layer meeting the technological requirement is achieved.
