Technical Field
The invention relates to the technical field of thermal spraying, in particular to a clamping device for a thermal spraying sample, which is suitable for thermal spraying of multi-process and multi-size samples in the preparation process of the sample.
Background
The thermal spraying technology is a coating preparation process which adopts a high-temperature heat source to heat a spraying material, so that the spraying material reaches a semi-molten, molten or atomized state and then is sprayed to the surface of a substrate at a high speed, thereby forming a coating with certain strength and thickness. Aiming at a heat source, thermal spraying can be divided into flame spraying, explosion spraying, electric arc spraying, plasma spraying and laser spraying, coatings with excellent performances of wear resistance, high temperature resistance, oxidation resistance, corrosion resistance and the like can be prepared by adopting different methods, and the process is widely applied to the fields of aerospace, mechanical manufacturing, petrochemical industry, biomedical treatment and the like.
Before batch production and processing, when technological parameters are optimized and in the sample preparation process, a multi-process and multi-size sample thermal spraying experiment is carried out, the size of a test block for the experiment is generally phi 10 mm-phi 25.4mm, the spraying particle flow speed is 100 m/s-900 m/s, and the flame flow temperature is 2000-20000 ℃. According to different experimental requirements, the number of prepared samples is different every time, and because in the thermal spraying process, high-temperature and high-speed particle flow has certain impact force on a matrix sample and is easy to deposit on the surface of the clamp, the spring embrittlement can be caused to some clamps adopting springs or iron clamps, so that the iron clamps lose clamping force due to burning deformation, the clamps are damaged, the service life of the clamps is shortened, and the test cost is high.
Disclosure of Invention
The invention aims to provide a clamping device for a thermal spraying sample, which realizes the clamping of the spraying of samples with various sizes and can avoid the damage of a tool caused by the deposition of a thermal spraying coating.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a hot spraying sample clamping device, it is including pressing from both sides the cover main part and setting up the compression pin in pressing from both sides the cover main part, baffle and supporting rod, the supporting rod is fixed in on the hot spraying revolving stage, it loads the hole site to have seted up a plurality of in the cover main part to press from both sides, place a sample in every loading hole site, the compression pin corresponds every and loads the hole site setting, and from the surface screw thread screw in of pressing from both sides the cover main part, and radial top tightly loads the sample in the hole site, per two baffles use in pairs and set up in the both sides of each compression pin, when compression pin along its axial screw in, when unscrewing, baffle synchronous motion, thereby form to shelter from in loading the hole site and.
Particularly, the clamping sleeve main body is provided with slots at two sides of the pressing nail, and the baffle is correspondingly inserted into the slots.
In particular, the baffle simultaneously abuts against the outer surface of the test specimen.
In particular, the length of the baffle is not less than the length of the hold-down pin.
In particular, both end faces of the sample do not protrude beyond the outer surface of the jacket main body.
In particular, the outer end of the holding-down pin is provided with a screw head which facilitates screwing.
Compared with the prior art, the hot spraying sample clamping device has the advantages that clamping of samples of multiple sizes and types can be achieved by adjusting feeding of the pressing nails, the pressing nails are covered by the movable baffle, failure caused by burning damage of the clamping parts can be avoided, service life is prolonged, the structure is simple, and adjustment and use are convenient.
