A bolt surface spray coating structure

Abstract

The invention discloses a bolt surface spraying and covering structure. The bolt surface spraying and covering structure is characterized in that an upper layer mounting plate and a lower layer mounting plate are arranged at a certain interval and arranged in parallel, the upper layer mounting plate and the lower layer mounting plate are fixedly connected through a fixing frame, a rotation shaft is rotatably connected onto the two layer mounting plates through bearings, two rotation cylinders are fixedly connected onto the rotation shaft, one of the rotation cylinders is placed above the upperlayer mounting plate, the other rotation cylinder is placed between the two mounting plates, brush bristles are fixed on the outer wall of each rotation cylinder, a plurality of insertion holes are formed in the circumferential direction of the upper layer mounting plate, a plurality of trays are rotatably connected in the circumferential direction of the lower layer mounting plate, each insertion hole and each tray are correspondingly arranged in a coaxial mode, the insertion holes and the trays are all located in the outer sides of the brush bristles, and a motor drives the rotation shaft to rotate through a speed reducer. The bolt surface spraying and covering structure is high in efficiency, realizes mechanical operation, reduces labor intensity of workers, and is good in use effect.

Description

Technical field: [0001] The invention relates to a bolt surface spray coating structure. Background technique: [0002] In order to prevent the bolt from rusting during use, it is usually necessary to coat the threaded surface of the bolt with grease. The grease coating of the existing bolts is manually painted, especially when the bolt is a bald screw structure (the bolt's There are threaded connection surfaces at both ends), after manually painting one end, you need to paint the other end, which is extremely inefficient and labor-intensive for workers. Invention content: [0003] The present invention provides a bolt surface spray coating structure in order to solve the above-mentioned problems in the prior art. [0004] The technical scheme adopted in the present invention includes: a bolt surface spraying structure, the bolt is a cylindrical structure, and a threaded connection surface is provided at both ends of the bolt, and the spraying structure is used for two bo...
