Abstract

The invention discloses a spraying supporting frame and a spraying device and belongs to the technical field of coating spraying. The supporting frame comprises a supporting rod; a height adjusting device is arranged on the supporting rod; and a universal ball is arranged at the bottom of the supporting rod. According to the supporting frame, by arranging the universal ball, the requirement of axial constant speed walking of the supporting frame on the inner wall of a mould cavity which rotates with the constant speed is met; by arranging the height adjusting device, the requirement that a supporting pushing rod reaches the level is met; and meanwhile the supporting frame is simple in structure, can be quickly mounted at the front end of the pushing rod and prone to disassembling, and does not affect the production rhythm.

Description

technical field

[0001] The invention relates to the technical field of paint spraying, in particular to the spraying of the inner wall of a mold cavity of a horizontal centrifuge. Background technique

[0002] Before using a horizontal centrifuge for centrifugal casting, it is necessary to spray a layer of coating on the inner wall of the mold cavity. The existing technology is to put the spray gun on the head of the push rod and extend the spray gun to the mold cavity by the push rod. The other end of the interior is then sprayed during the process of pulling the push rod back; during the process, the front end of the push rod naturally droops due to gravity, and with the retraction of the push rod, the head of the drooping push rod gradually returns to the required height, so that During the spraying process, the spray gun forms a process from low to high during the movement of the inner wall of the mold cavity, which makes the coating on the inner wall of the mold cavity ...
