Description

Technical Field

[0001] The utility model relates to the technical field of spraying shielding jigs, in particular to a plasma spraying shielding jig. Background Art

[0002] Plasma spraying is a technology for strengthening and modifying the surface of materials. It can make the substrate surface have the properties of wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, friction reduction and sealing. Plasma spraying technology is widely used in various fields. For example, the wear resistance and corrosion resistance of the surface of rollers, bottom rollers and other parts in the steel industry can be increased by plasma spraying. For this purpose, a plasma spray knock-off fixture is proposed.

[0003] The existing referenceable Chinese utility model patent with announcement number CN217127512U discloses a plasma spray shielding jig, which includes a load-bearing plate, a group of support components are installed on the bottom surface of the load-bearing plate, a group of anti-slip strips are installed on the upper surface of the load-bearing plate, two square frames are arranged above the load-bearing plate, and two hydraulic rods are installed on the bottom surface of the two square frames, and each hydraulic rod is embedded in the outer surface of the load-bearing plate. It can be coordinated with the load-bearing plate, anti-slip strips, square frames, hydraulic rods, support strips, limit frames, shielding plates, clamping components and snap-on components. The hydraulic rod can drive the shielding plate to move downward and can shield the upper surface of the parts. The clamping components and snap-on components make the device very convenient and quick to disassemble the shielding plate, and can easily change the shape and size of the spray, so that the device can meet the spraying requirements of different parts.

[0004] In the process of using the existing plasma spraying masking jig, since some equipment only needs to spray the designated area during spraying, direct spraying without any obstructions will cause a large area of ​​the equipment to be sprayed, which increases the spraying area and affects the overall aesthetics of the equipment. It also causes a waste of plasma spraying raw materials, and the equipment is not clamped during spraying, which requires manual turning over of the equipment during spraying, which not only increases the labor workload, but also affects the spraying efficiency of the equipment, which needs to be improved. Therefore, a technician in this field provides a plasma spraying masking jig to solve the problems raised in the above background technology. Utility Model Content
