Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder thermal spraying, and more specifically to a spraying part fixing device of a powder thermal spraying rotating frame. Background Art
[0002] Thermal spraying is a process of heating and melting the coating material, atomizing it into extremely fine particles with a high-speed airflow, and spraying it onto the surface of the workpiece at a very high speed to form a coating. During thermal spraying, the sprayed part needs to be stably fixed and the powder thermal spray rotating frame needs to be used to drive the sprayed part to rotate.
[0003] Common spray-coated parts fixtures use manual locking or two-way clamping of air / hydraulic cylinders. After clamping, the parts to be sprayed remain in a fixed state, and the parts to be sprayed are sprayed by rotating the powder thermal spraying rotating frame. The spray-coated parts fixture itself does not rotate. For spray-coated parts of different sizes and shapes, there will be some blind spots in the spraying process relying solely on the rotation of the external rotating frame, because the structure of the fixture itself may affect the spraying range. Therefore, the structure of the spray-coated parts fixture itself needs to be improved. Utility Model Content
