Thin and long inner hole workpiece spraying construction device and spraying method adopting same

Abstract

The invention provides a thin and long inner hole workpiece spraying construction device and a spraying method adopting the thin and long inner hole workpiece spraying construction device. The thin and long inner hole workpiece spraying construction device comprises a main support and a spray head support. The main support comprises two coaxially arranged main support end plates (8), and the two main support end plates (8) are fixedly connected to form a whole. At least three radially arranged telescopic supporting legs (2) are fixedly arranged on each main support end plate (8). Rollers (7) are fixed to the ends, away from the main support end plates (8), of the telescopic supporting legs (2), and therefore the main support can move in a thin and long inner hole in the length direction ofa spindle (1). The spray head support can move in the length direction of the spindle and can rotate around the surface of an inner hole of the spindle (1). The spray head support is rotationally fixed to the main support. The distance between a spray head and the surface of a workpiece can be kept constant, and therefore the effect of homogeneously spraying all the positions of the surface of the inner hole is kept. In addition, the device allows construction to be carried out from one side of the inner hole of the spindle, and the surface of the whole inner hole of the spindle can be continuously sprayed.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a spraying construction device for workpieces with elongated inner holes and a spraying method using the same. Background technique [0002] With the rapid improvement of my country's economic development and people's living standards, my country's electricity demand is increasing year by year. In 2013, the total electricity consumption of the whole society was 5,322.3 billion kwh, a year-on-year increase of 7.5%. By 2030, the national electricity demand will reach 10-11 trillion kwh, and by 2050, the national electricity demand will reach 12-15 trillion kwh. For a long time, coal has been in a dominant position in my country's energy consumption structure. The coal-based energy consumption structure and extensive growth mode have caused a great threat to my country's ecological environment. At present, the total global carbon dioxide emissions have reached more than 36 billion...

Problems solved by technology

[0009] In order to solve the above-mentioned technical problems of uneven spraying effect and difficult spraying construction of special spindles, the present invention provides a spraying construction device and spraying construction method for slender inner hole workpieces

The device of the present invention can well solve the construction difficulty caused by the too long inner hole of the workpiece. At the same time, although the diameters of the inner holes at different positions along the length direction of the main shaft are different, the device of the present invention can still maintain the distance from the nozzle to the surface of the workpiece. Constant for uniform spraying across the bore surface
