Abstract

The invention discloses a blade spraying protective fixture which is used for being connected to spraying equipment so as to protect the lower surface of a blade edge plate and a tenon. The blade spraying protective fixture comprises a fixture body, a first stopping block, a second stopping block and locking pieces, wherein the fixture body is used for being connected with the spraying equipment and provided with a containing groove used for containing the tenon; the containing groove penetrates through the two side walls of the fixture body and communicates with the upper end surface of the fixture body; outwards convex positioning flanges extending in the length direction of the containing groove are symmetrically arranged on the two side walls of the containing groove so as to be used for supporting and positioning the long edges of the blade edge plate and enabling the upper surface of the blade edge plate to be exposed out of the upper end surface of the fixture body; the first stopping block and the second stopping block are arranged at the two ends in the length direction of the containing groove correspondingly so as to be used for blocking the two ends of the containing groove and being matched with the positioning flanges to support and position the short edges of the blade edge plate; the first stopping block and the second stopping block are both partially embedded in the containing groove and abut against the tenon located in the containing groove so as to clamp and fix the tenon; and the locking pieces are used for locking the first stopping block and the second stopping block with the fixture body.

Description

technical field [0001] The invention relates to the field of blade spraying, in particular to a blade spraying protective fixture. Background technique [0002] Vacuum plasma spraying is the plasma spraying that places the workpiece, turntable, spray gun, etc. in a closed vacuum chamber. Vacuum plasma spraying avoids oxidation in the atmospheric environment, and the cleaning effect of the transferred arc can make the surface of the workpiece cleaner, which is beneficial to the coating and coating. Therefore, vacuum plasma spraying technology is widely used in aero-engine turbine components, which has better resistance to high-temperature oxidation, high-temperature corrosion, and high-temperature sealing. [0003] The turbine working blade of a certain type is vacuum plasma sprayed with nickel-cobalt-chromium-aluminum-yttrium-tantalum coating. The process requires spraying the entire blade body and the upper surface of the edge plate. The thickness of the coating is controll...
