Description
Technical field
The utility model relates to the clamping device of quantitative monitoring conversion reference precision.
Background technology
No-residual length leaf (water passage surface of blade does not have surplus) processing generally is to be other positions that benchmark is processed blade with six anchor points on the blade; But when six point locations are directly processed blade; Because blade receives the effect of thrust and cutting force and is prone to make blade to be weighed wounded; Hollow blade is particularly serious; Causing and weigh wounded for fear of directly compressing blade, adopt the method for cast low-melting alloy that the blade benchmark is transformed on the alloy block at present usually, is that benchmark is processed other surperficial methods of blade again with the alloy block.So just produce a problem: because the machining tolerance of the tolerance of processing of leaves dimensional tolerance=conversion benchmark ten conversion benchmark rear blades; The tolerance size of conversion benchmark directly influences the machining tolerance of next procedure; The tolerance of conversion benchmark is big more, and the machining tolerance of subsequent processing is more little.
Summary of the invention
The purpose of the utility model is to provide a kind of six anchor points on the blade is transferred on the alloy locating piece and clamping device that can quantitative monitoring conversion reference precision accurately.
The utility model provides a kind of clamping device of quantitative monitoring conversion reference precision, it is characterized in that: mainly comprise anchor clamps, dial framework, magnetic force dial framework, dial gauge and low-melting alloy; Anchor clamps by base plate, low-melting alloy limited block, positioning support, compress bearing, alignment pin, hold-down mechanism and form; Low-melting alloy limited block, hold-down mechanism and alignment pin are fixed on the base plate; Compressing bearing is fixed on the base plate respectively near the low-melting alloy limited block and/or compresses on the bearing; Positioning support is fixed on the base plate, is equipped with on the low-melting alloy limited block on keeper and the positioning support and is equipped with keeper; The magnetic force dial framework places on the anchor clamps, uses alignment pin spacing respectively, and dial framework is fixed on the magnetic force dial framework, and dial gauge is housed on the dial framework.
The clamping device of the quantitative monitoring conversion reference precision that the utility model provides, its dial framework can have 2, and the magnetic force dial framework has 2.
The clamping device of the quantitative monitoring conversion reference precision that the utility model provides, its dial gauge can have 6.
