Abstract

The invention relates to bore-rotating plasma spraying special equipment which comprises a powder, plasma gas, shielding gas, cooling air, cooling water inlet and backwater rotary conveying mechanism, an electric slip ring, a transmission mechanism, a coupling assembly and the like. Through the equipment, a bore plasma spraying gun can rotate 360 degrees continuously and endlessly, and stable transmission of powder, plasma gas, cooling air, cooling water inlet and backwater and current can be guaranteed. The equipment is suitable for plasma spraying of automobile engine cylinder bores, cylinder sleeves and other bore parts. The rotating plasma spraying equipment can make the bore gun rotate 360 degrees continuously and maximize the spraying distance by the utilization of centrifugal force so as to guarantee enough spraying distance, avoid overheating of workpieces, reduce internal stress and ensure coating quality.

Description

technical field [0001] The present invention relates to the field of thermal spraying of surface engineering technology, and plasma spraying of inner holes of parts. In particular, it involves plasma spraying of cylinder bores, cylinder liners and other inner holes of automobile engines. Background technique [0002] Thermal spraying technology can solve problems such as wear resistance, anti-corrosion, insulation, conductivity, increase friction, reduce friction, etc., and change the surface characteristics of parts. Plasma spraying is an important process method in thermal spraying technology. The plasma flame temperature of plasma spraying is high, and the temperature of the nozzle of the spray gun can reach 18000 degrees. The distance of plasma spraying is generally 70~150mm. The temperature is generally several thousand degrees. The difficulty of spraying parts with inner holes is that too small inner holes cannot guarantee a sufficient spraying distance, which will...
