Description

Turbine sand washing fixing device

Technical Field

The application relates to the technical field of fixing devices, in particular to a turbine sand washing fixing device.

Background

Sand washing, also called sand blasting, is a process of cleaning and roughening the surface of a matrix by using the impact action of high-speed sand flow. The sand blasting adopts compressed air as power to form a high-speed spray beam to spray blasting materials (such as copper ore sand, quartz sand, carborundum, iron sand and Hainan sand) to the surface of a workpiece to be treated at high speed, so that the appearance or the shape of the outer surface of the workpiece surface is changed. Due to the impact and cutting action of the sprayed material on the surface of the workpiece, the surface of the workpiece obtains certain cleanliness and different roughness, and the mechanical property of the surface of the workpiece is improved. Therefore, the fatigue resistance of the workpiece is improved, the adhesive force between the workpiece and the coating is increased, the durability of the coating is prolonged, and the leveling and decoration of the coating are facilitated.

In the manufacturing process of the turbine, the turbine is also required to be sandblasted. The blasting operation is usually performed by manually clamping the turbine and taking it to the position of the blasting gun. In the process of actual production, because the turbine is various in kind, and shape, size all have the difference, go on through the manual work to rely on the processing mode of manual work to the adjustment of position and angle, need consume a large amount of manpowers and time. And the environment of the sand blasting operation is severe, and the harm to the health of people caused by sand blasting by manually clamping the turbine in a close range is large. In addition, when the turbine with small size and difficult clamping is subjected to sand blasting operation, the clamping part is small, so that the workpiece is difficult to fasten for operation, the situation that the workpiece is easy to fall off the hand is easy to happen, and the potential safety hazard is large. Therefore, the manual clamping sand blasting operation has the problems of low processing efficiency, severe working environment, potential safety hazard and the like.
