Abstract
The utility model relates to a tool for detecting arcs of blade root bosses of a gas turbine blade. The tool is characterized in that the tool comprises a locating body and a measuring body, the locating body is provided with a tooth-shaped groove, the bottom of the tooth-shaped groove is provided with jackscrews, the measuring body is fixed at one end of the locating body located at the tooth-shaped groove, an upper surface of the measuring body is an arc-shaped measuring surface, and the arc surface radius of the arc-shaped measuring surface is equal to the arc surface radius of an arc of a blade root boss. According to the tool for detecting the arcs of the blade root bosses of a gas turbine blade, in use, the blade root is inserted into the tooth-shaped groove, and the blade root boss is exposed, the jackscrews support the blade root so as to be firmly combined with the tooth-shaped groove, which is the same as a bearing surface in actual assembling, then whether a gap between a blade root boss arc-shaped surface and the arc-shaped measuring surface are in a required range can be obtained through light leakage detection and filler gauge detection, and the detection tool can also play the role of a go/no-go gauge and measure the size of the tooth type, the influence of tolerance is small, the detection result is stable, the detection is easy and can be realized by only one person, the structure is simple, the cost is low, and the detection tool is easy to manufacture and has remarkable effects.
Description
Technical field
The utility model relates to a kind of turbine blade testing tool, particularly relates to a kind of combustion machine blade root boss circular arc testing tool.
Background technology
In the production of palm blade profile turbine blade, generally all be respectively equipped with arc cam in blade root two ends turnover gas side and be used for assembling and positioning, its arc-shaped surface dimensional requirement is higher, guarantee assembly precision, so it is very crucial carrying out in production process that size detection checks and approves, in order to avoid being stayed the assembling link, problem influences manufacturing schedule, existing measurement is generally directly measured with vernier caliper or is compared with comparison block, its measuring error is big, it is poor to measure stability and consistance, be not easy to measure, be unsuitable for measuring in the batch machining, bigger to producing influence.
The utility model content
In order to solve the deficiency that exists in the above-mentioned blade root boss circular arc detection, the utility model provides a kind of combustion machine blade root boss circular arc testing tool.
The technical solution adopted in the utility model is: a kind of combustion machine blade root boss circular arc testing tool, it is characterized in that comprising positioning body and measure body, positioning body is provided with the flute profile groove, the flute profile trench bottom is provided with jackscrew, measure body and be fixed on an end that is positioned at the flute profile groove on the positioning body, measure above the body and measure face for arc, the cambered surface radius that arc is measured face equates with the cambered surface radius of blade root boss circular arc.
Described flute profile groove inner bottom part is provided with top board, jackscrew be two withstand on below the top board on.
Be covered with moccasin or plastic layer above the described top board.
Described measurement body is by register pin and being bolted on the positioning body.
Described measurement body inboard is covered with moccasin or plastic layer.
Be equipped with screw on two ends, the left and right sides positioning body of described flute profile groove, measure left end or the right-hand member of body by being bolted to the flute profile groove.
When the utility model uses blade root inserted that the blade root boss exposes in the flute profile groove, with jackscrew jack-up and flute profile groove strong bonded, load-carrying surface during with practical set is identical, detect by light leak then and clearance gauge detects the gap that can obtain between blade root boss arcwall face and arc measurement face whether in claimed range, the only effect of drift of can also playing is simultaneously measured the size of flute profile, be subjected to tolerances little, testing result is stable, detecting an easy people gets final product, cost simple in structure is low, be easy to make, effect is remarkable.
