The lower end of described mast is arranged in transfer panel and fixes by clamp nut.
Described mast is at least provided with 5, and the diameter of described mast is 8mm.
Described pad is at least provided with 10, and the external diameter of pad is not less than 12mm, and thickness is not less than 2mm.
Distance and part height between described adjacent two pads are measure-alike.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, when perfection solves the large workpiece of plasma spraying thin-walled flexible circular, process centering problem, realized the fast aligning of workpiece, round to the heart and school.Parts fixation speed significantly promotes, and shortens to 20 minutes by original about 1 hour;
2, greatly reduce spraying operating personnel labour intensity and technical difficulty, handled easily person to the installation of workpiece with take, use manpower and material resources sparingly.By frock centering and the placing part that originally must have 2-3 people to cooperate just to complete, present 1 people just can complete smoothly;
3, use after special fixture, can once spray at most 10 workpiece, each production class calculated and can spray 18-20 part according to 8 hours, had increased substantially labor productivity;
4, special fixture, in the multiple workpiece of spraying, can effectively improve the deposition efficiency dusting on part, thereby greatly reduces the stealth waste of dusting in space.Workpiece dust consume from improve 0.45Kg/ part be reduced to 0.30Kg/ part, effectively reduce production cost;
5, this Self-positioning clamp can be widelyd popularize in military and civilian's product of other similar thin-walled flexible circular part plasma spraying external diameter and foreign trade part.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front first centering bearing on turntable of processing, and to the fixing schematic diagram of bearing;
The fixing schematic diagram of installation of Fig. 3 positioning disk;
Fig. 4 sprays the installation of part;
Reference numeral: 1-mast, 2-part, 3-pad, 4-transfer panel, 5-clamp nut, 6-bearing, 7-turntable, 8-boss.
Five, detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Referring to Fig. 1: the Self-positioning clamp of plasma spraying flexible circular workpiece external diameter, comprise transfer panel 4, described transfer panel 4 is circular ring type, the circumference of the interior annulus of described transfer panel 4 is set to boss 8, in the circumferential edge of described transfer panel 4 upper surfaces, be provided with the mast 1 of several Equal round side faces, on each mast 1, be disposed with from top to bottom some layers of pad 3, the position dimension of described mast 1 and the internal diameter of processing parts 2 match.
The lower end of described mast 1 is arranged in transfer panel 4 fixing by clamp nut 5.
Described mast 1 is at least provided with 5, and the diameter of described mast 1 is 8mm.
Described pad 3 is at least provided with 10, and the external diameter of pad 3 is not less than 12mm, and thickness is not less than 2mm.
Distance and part height between described adjacent two pads 3 are measure-alike.
Below the utility model is elaborated: Part I:
1, be designed to starting point and opportunity with existing universal support saddle 6, the problem of centering difficulty while solving annular workpieces plasma spraying.Universal support saddle 6 is after a centering clamping, and the fixture matching with it can be realized quick switching, has once felt relieved;
2, the switching disk 4 that design and universal support saddle 6 match, the boss 8 at the interior annulus of transfer panel 4 place and the groove of bearing 6 are coincide mutually, solve with this problem matching with accessory size, in addition, consider the larger Φ 789.5mm of workpiece size, transfer panel 4 is set to circular ring type, and the circular hole at center is lightening hole, alleviates frock deadweight;
3, on switching disk, assemble 5 uniform Φ 8mm masts 1, mast 1 position dimension and part internal diameter match, and for retaining element, and realize quick centering, the location to each spray piece, large to solve part deformation, the problem of centering difficulty;
4, between the part of each placement, be greater than with thickness the pad that 2mm external diameter is no more than Φ 12 and mutually isolate, when ensureing plasma spraying, part chamfering has enough processing spaces, prevents the coating adhesion of adjacent workpieces.
Part II:
This new and effective fixtures for painting adopts the self-align and spacing principle of fixture of frock.Use locating dowel pole pair spraying workpiece to carry out spacing, solved the problem of large thin-wall around property part centering difficulty; Operator only need carry out centering to universal support saddle, can ensure to spray workpiece and have good positional precision, greatly reduces spraying operating personnel's labour intensity and technical difficulty.
Manufacture and design this fixture only sprays external diameter characteristic according to workpiece, can consider the disposable whether simultaneously multiple workpiece of clamping, in the time that spraying workpiece is installed, between each workpiece, should adopt pad to isolate, mutual interference problem between part while avoiding spraying; Meanwhile, during by corresponding adjustment spraying, plasma gun displacement and translational speed, just can realize the multiple workpiece of disposable spray finishing, increased substantially spraying operating efficiency.
