Description

Swing frame surface plasma spraying device Technical Field The invention belongs to the technical field of plasma spraying, and relates to a swing frame surface plasma spraying device. Background The swing frame is used as outdoor common recreation facilities and sports equipment, metal structural components (such as upright posts, cross beams, brackets and the like) of the swing frame are exposed in natural environments for a long time, and are required to bear various weather conditions such as wind blowing, sun drying, rain spraying and the like, so that the problems of rust erosion, abrasion and the like are easily caused, the service life and the safety are seriously influenced, in order to solve the problem, the plasma spraying technology is often adopted in the industry to treat the metal surface of the swing frame, and a layer of compact protective coating (such as a ceramic coating, an alloy coating and the like) is formed on the surface of the swing frame so as to enhance the corrosion resistance, the abrasion resistance and the oxidation resistance of the swing frame. At present, the plasma spraying device for swing frame surface treatment has a plurality of defects: In the aspect of workpiece fixing, the existing device mostly adopts a simple clamp or manual supporting mode, is difficult to adapt to the fixing requirements of swing frames with different specifications, has poor fixing stability, and is easy to cause uneven coating thickness due to workpiece shaking in the spraying process; in angle adjustment, the spray angle and workpiece posture adjustment of the traditional device depend on manual operation, so that the labor intensity is high, the comprehensive spray of complex curved surfaces (such as pipe fitting corners and arc-shaped connecting parts) is difficult to realize, and spray dead angles are easy to appear; during the turn-over operation, the swing frame on one side after the spraying is finished needs to be manually turned over and then is fixed again, the operation is complicated, potential safety hazards exist, and meanwhile, the workpiece is easy to cause positioning deviation due to repeated disassembly and assembly, so that the connection precision of the two-side coatings is affected; in the aspect of spray head distance control, the distance between a spray head and a workpiece of the existing device is mostly a fixed value or needs manual adjustment, real-time self-adaptive adjustment cannot be performed according to workpiece profile change, and therefore coating thickness differences at different positions are large, and protection effects are affected. Therefore, we propose a swing frame surface plasma spraying device for solving the above-mentioned problems.

As a further improvement of the above technical scheme: The turnover mechanism comprises a motor I, a rotating shaft I, a rotating frame and a mounting bracket, wherein the rotating shaft I is rotationally arranged at the top of the frame through a bearing seat, the rotating frame is fixedly connected with the outer wall of the rotating shaft I through a fixed base and a clamping seat, the mounting bracket is arranged at the top of the rotating frame, a plurality of suckers I used for adsorbing and fixing the swing frame are arranged at the top of the mounting bracket, the motor I is fixed at one side of the frame, and the output end of the motor I is fixedly connected with the rotating shaft I.
