Background technology
At present, the processing of nuclear-power nickel-base material impact toughness sample at home and abroad all is a difficult problem, and the key dimension of this type of impact toughness sample requires as follows, and dimensional accuracy is 10 ± 0.06mm; Perpendicularity is 0.10mm; Because nuclear-power nickel-base material is non magnetic, therefore the hardness height can only adopt traditional diamond-making technique, a crucial step of traditional diamond-making technique is to carry out " single-piece " grinding at grinding machine, yet the single-piece grinding efficiency is the end very, and this has just directly influenced the progress that nuclear island primary device is produced; In addition, the machining accuracy of traditional diamond-making technique is low, and the processing precision direct influence impact flexibility performance assessment criteria of impact toughness sample, this impact flexibility performance assessment criteria, be one of indispensable technical data, its whether qualified nuclear island primary device safety that concerning is normally moved.This shows that traditional diamond-making technique more and more can not satisfy the processing request of impact toughness sample.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of convenient, efficient, the reliable processing tooling clamp of nuclear-power nickel-base material impact specimen of safe and reliable, positioning accuracy, to solve the processing difficulties of nickel-base material impact toughness sample, improve the machined operating efficiency, and effectively guarantee operator's safety.
A kind of processing tooling clamp of nuclear-power nickel-base material impact specimen described in the utility model, it comprises a clamp base and several lateral expansion compactors that is connected with this clamp base,
The upper surface of described clamp base is interval with several two stage steps grooves, and each two stage steps groove is followed successively by width upper slot, intermediate channel and lower channel from large to small along direction from top to bottom;
Described lateral expansion compactor comprises that a steel tank, is embedded in the gad and a screw on this steel tank top, and the width of described steel tank bottom and the width of described lower channel are complementary, and described screw passes gad successively fixedlys connected with described lower channel with steel tank.
In above-mentioned processing tooling clamp of nuclear-power nickel-base material impact specimen, the number of described two stage steps groove is three, and in each two stage steps groove two described lateral expansion compactors is set at interval.
Owing to adopted above-mentioned technical solution, the utility model has effectively prevented nickel-base material impact toughness sample perpendicularity deviation and key dimension bias phenomenon, improved the machining accuracy of nickel-base material impact specimen, make the sample mass of processing meet pendulum impact test method requirements such as GB, ASME, RCCM, ISO fully, thereby guaranteed the quality of nuclear power product; Simultaneously, the utility model has also improved the environment of employee's operation planar grinding machine processing nickel-base material impact specimen greatly, has improved the security and the working (machining) efficiency of processing.
