Important spare part, such as axle, gear, cam and roll, are usually failed due to abrasion and contact fatigue, even result in complete machine
Scrap, cause great waste.In order to solve to cause due to surface damage scrapping for complete machine, a series of advanced surface works
Journey technology, such as plating, Brush Plating, thermal spraying, are developed rapidly.Wherein, plasma spray technology be using flame, electric arc, etc.
The thermals source such as ion arc, melting or semi-molten state are heated to by powdered (or silk material, bar) material, while to this material grain
Son is accelerated, and is hit matrix quick cooled and solidified after flattening and is deposited on surface of the matrix surface formation with specific function
Paint-on technique, stronger advantage is shown in terms of the surface damage reparation of modern project structural elements is solved.
In order to examine the repairing quality and persistence of wear-resistant coating prepared by plasma spray technology, actual repair part is being carried out
Stand examination before, it is necessary to first in laboratory conditions the real working condition of simulation coating " skid " contact to the annular standard of thermal spraying
Roller (being referred to as ring specimen in this patent) carries out test of many times checking.
At present, in annular standard rod spraying process, for the clamping of annular standard rollers, generally using suitable annular standard rod
The cylindric frock clamp of internal diameter, multiple annular standard rods are conspired to create after a string, are fixed on turntable, by moving spray gun,
The cambered surface prepares coating of annular standard rod.Such as a kind of annular test-piece clamping and fixing device, application number：201520512144.5,
The day for announcing：2015.12.16, multiple ring specimens are conspired to create a string by cylindric clamping part, is then fitted into the card on turntable
On disk, the fixation to multiple ring specimens is completed.Once multiple ring specimens are fixed although this mode can be realized, by turn
The influence of centering in platform rotation process, the homogeneity of prepared coating is difficult to ensure that, is degrading the performance of coating.In addition, working as
When multiple ring specimens are mutually abutted, the spraying of ring specimen cambered surface can only be realized, can not be sprayed sideways, and in spraying
During can gap between two adjacent ring specimens form coating, cause adhesion between ring specimen, it is necessary to
The mode such as wire cutting or emery wheel is cut, and so not only reduces efficiency, and one procedure of increase may deteriorate the matter of coating
Amount.
Therefore, how to be better achieved in thermal spray process and once spray multiple ring specimens, efficiency is improved, as ability
The problem of field technique personnel's urgent need to resolve.
The content of the invention
There is the equal of coating when being for once spraying multiple ring specimens in current thermal spray process in the purpose of the present invention
One property is difficult to ensure that, can not be sprayed sideways and ring specimen between the not enough of adhesion tried there is provided a kind of thermal spraying annular
Part frock clamp.The device carries dovetail groove profile sliding rail by base, and coordinate with sliding block chuck to be set not exactly
With spray distance, also, the design independently fixed using ring specimen can once be sprayed in thermal spray process it is many
Individual ring specimen, and ensure that the homogeneity of coating, realize ring specimen cambered surface and the spraying of side and avoid annular
The frock clamp of adhesion between test specimen.
The technical scheme is that：
A kind of thermal spraying ring specimen frock clamp, the fixture includes base, sliding block chuck and baffle plate；
Wherein, described base is stainless steel materials, and sheet material top is provided with the dovetail groove of front and rear insertion by cutting；
Described sliding block chuck includes sliding block and chuck；Sliding block is that both sides are provided with the stainless steel materials on domatic inclined-plane, width,
The angle on domatic inclined-plane is matched with the dovetail groove of base；Chuck is the U-lag of left and right insertion, length and the length phase of sliding block
Deng, and be welded on the rear portion of sliding block, the cell wall of collet front and be evenly distributed with tapped through hole；Baffle plate is vertically placed on chuck
In U-lag, fastening bolt is fixed on sliding block chuck by the tapped through hole on chuck cell wall；There is matrix distribution on baffle plate
Through hole, for stationary annular test specimen；
Described matrix distribution is n rows × m row, wherein, n=3~5, m=4~6.
Beneficial effects of the present invention are：
The present invention will solve once to spray in current thermal spray process by the design for independently fixing ring specimen
The uniformity that there are problems that coating during multiple ring specimens is difficult to ensure that, improves the quality of coating and thermal jet greatly improved
Coating layer preparation efficiency.In addition, the present invention can realize the spraying of ring specimen cambered surface and side, it is to avoid annular after thermal spraying
The problem of adhesion and subsequent treatment process may deteriorate coating quality between test specimen, improve hot-spraying coating quality,
The performance of coating is lifted, contributes to the further genralrlization application of coating technology in the industrial production.It is embodied in：
(1) prior art is to conspire to create a string, rotates spraying, ring specimen is to rotate, and this technology is to use to divide
Not independent fixed mode, is that ring specimen is static in spraying process, so coating can be more uniform；
(2) contact that independent fixed mode is avoided between ring specimen side ensure that each face can coated
Covering, and avoid the adhesion after ring specimen is sprayed again because conspiring to create a string between ring specimen, and follow-up place
Science and engineering sequence can deteriorate the quality of coating；
(3) dovetail groove profile sliding rail is carried by base, different sprays can be set exactly by coordinating from sliding block chuck
Apply distance.
