Interior the second mounting blocks (41), each mounting blocks upper surface are fixed with Almen test piece (5) by screw (7).
8. torsion beam shot-peening according to claim 7 detects fixture, it is characterised in that：First mounting blocks (33) height
Less than the connection sheet (32) height and be held on surface installation Almen test piece (5) flushed with torsion beam outer surface；
Second mounting blocks (41) are highly higher than the height of the connection sheet (32) and are held on the Almen test piece of surface installation
(5) flushed with torsion beam inner surface.
9. a kind of torsion beam shot-peening detection fixture using as described in any claim in claim 1~8 carries out shot-peening inspection
The method of survey, it is characterised in that include the following steps：
1. new Almen test piece is taken out, sequence number corresponding with each mounting groove on mark, the Almen of utilization calibrated mistake
Strength tester detects the initial value of every piece of Almen test piece and makes a record；
2. the Almen test piece for indicating sequence number is fixed on mounting blocks by hexagon socket head cap screw, then Almen test piece will be housed
Mounting blocks be fixed on stent, be fixed on torsion beam by the welding of the stents of the different mounting grooves of correspondence or by hexagon socket head cap screw
On exemplar；
After 3. installation is complete, the torsion beam exemplar equipped with Almen test piece is put into wheel abrator cabinet, by stationary fixture by torsion
Beam exemplar is separately fixed on inner surface shot-peening station or outer surface shot-peening station, using blasting machinery arm and swivel nozzle according to
The movement locus of setting carries out surfaces externally and internally shot peening strengthening to torsion beam exemplar.
4. after the completion of blasting process, torsion beam exemplar is taken out, removes the Almen test piece on mounting blocks, it is recessed using endoscope check
The coverage rate in strip is cheated, the deformed camber value of Almen strength tester test strip is recycled, with defined arc
High level and coverage rate desired value are contrasted, and judge whether test result meets the requirements.
10. the method according to claim 9 for carrying out shot-peening detection using torsion beam shot-peening detection fixture, its feature exist
In：Outer surface 0.25~0.35Mpa of pressure, 23~25KG/Min of flow, 90~100s of net shot-peening time；Inner surface shot-peening
0.45~0.55Mpa of pressure, 8~10KG/Min of flow, 85~95s of net shot-peening time, 95~105mm/Min of lifting speed.
