Description
Technical field
This utility model relates to a kind of fixture, particularly relates to a kind of thermal spraying experiment specimen holder, belongs to thermal spraying apparatus technical field.
Background technology
Plasma spray technology refers to utilize certain thermal source to be heated rapidly to sprayed on material dissolve or half melting state, it is made to be atomized through high velocity air or flame stream again, accelerating jetting is on pretreated piece surface, material surface is made to be strengthened and modified, it is thus achieved that to have the material surface complex technique that a kind of application on certain function (such as wear-resisting, anticorrosion, high temperature resistance etc.) surface is the strongest.Plasma spray technology has and involves a wide range of knowledge, and processing technique is relatively easy flexibly, applied range, the feature that economic benefit is big, and therefore the every field in national economy has vast potential for future development.
When carrying out thermal spraying production or experiment, matrix sample used mostly uses rectangular block or the disk of fixed dimension, and is mostly metal.According to different experiment demands, the quantity every time preparing sample is different, typically at 3 ~ 10.Owing to, in thermal spray process, the particle flux of high temperature and high speed has certain impulsive force to matrix sample, and matrix specimen temperature raises simultaneously, the matrix specimen holder therefore finding a kind of practicality is the precondition that laboratory is smoothed out thermal spraying experiment.Existing thermal spraying fixture kind is a lot, but the specimen size underaction that can load and unload, it is impossible to adapt to several various sizes of sample simultaneously and be installed and spray.Also have some in spraying process, the effect experiencing circulation of repeatedly expanding with heat and contract with cold under the impact of high-temperature hot spraying flame stream was easily lost efficacy, or scrap because being difficult to clear up after depositing thicker coating on fixture, the movable whorl part of some fixture extremely easily forms coating in spraying process so that it is cannot continue to need to use；Also some is owing to manufacturing cost is the highest and impracticable, there is presently no the special fixture being found particularly suitable for field of thermal spray.
Summary of the invention
This utility model purpose is to provide a kind of thermal spraying experiment specimen holder, and this fixture is applicable to thermal spraying laboratory various spraying sample.
This utility model is achieved through the following technical solutions: thermal spraying experiment specimen holder of the present utility model includes clamping main part, clamping duplicate, covering, clamping duplicate is arranged in the rectangular opening of clamping main part by more than one connecting screw, and fixed by fastening screw I, covering is arranged on clamping main part and is positioned at outside rectangular opening.
The retaining part of described clamping duplicate is bar shaped step or is made up of more than 2 arc-shaped step, can coordinate with the clamping step inside clamping main part rectangular opening and fix sample.
Described thermal spraying experiment specimen holder can clamp various sizes of square or circular specimen by changing clamping duplicate.
Having regulating tank in described covering, regulating tank matches with the fastening screw II on clamping main part.
During use, shape according to clamping sample, clamping duplicate is arranged in the rectangular opening of clamping main part by connecting screw, then sample is positioned in rectangular opening, by regulation fastening screw I, make specimen holder between the clamping step inside the retaining part and clamping main part rectangular opening of clamping duplicate, the height of retaining part step is identical with the clamping shoulder height inside clamping main part rectangular opening, thus complete the fixing of sample, regulating tank in covering matches with fastening screw II, covering is made to be fixed on clamping main part, screw is protected, prevent the deposition of spraying process floating coat, finally the fixture assembled is installed on the scroll chuck of turntable.
The beneficial effects of the utility model are: by changing difference clamping duplicate, it is achieved the clamping to different size shape sample；The curtain-shaped cover member arranged prevents coating from depositing on screw, improves the service life of fixture；This apparatus structure is simple, and flexible function is various, with low cost, and handling sample is convenient, and plastic simplicity is attractive in appearance, reasonable in design；Fixture easy cleaning, reusable.

Detailed description of the invention
Being described in further detail this utility model with detailed description of the invention below in conjunction with the accompanying drawings, this utility model protection domain is not limited to described content.
Embodiment 1: such as Fig. 1, 3, 4, 6, 7, shown in 8, this thermal spraying experiment specimen holder includes clamping main part 1, clamping duplicate 2, covering 4, 2 connecting screws 5 are attached with clamping duplicate 2 by the screwed hole of clamping main part 1 side, clamping duplicate 2 is arranged in the rectangular opening 3 of clamping main part 1, the retaining part of clamping duplicate 2 is for be made up of 9 arc-shaped step, shoulder height with clamping main part 1 rectangular opening 3 inside clamp step 12 the most identical, sample 8 is fixed on inside the arc-shaped step of clamping duplicate 2 and rectangular opening 3 by the screwed hole on clamping main part 1 and clamps between step 12 by 2 fastening screws I 9；Covering 4 is to have the strip sheet metal of regulating tank 7, and fastening screw II 6 coordinates with regulating tank 7, covering 4 is fixed on the top of clamping main part 1 and is positioned at outside rectangular opening, being installed on the scroll chuck of turntable by the fixture assembled.
