Technical field

The invention belongs to aero-engine and gas-turbine engine Blade precision forging fields, and in particular to a kind of precision forged blade is non- Tangent switching fillet detection template component and measurement method.

Background technique

Blade is the important component of aero-engine and gas turbine.Blade construction is complicated, and required precision is high, production and inspection It is long to survey the period.Part precision forged blade tenon mounting plate and blade type face switching fillet blade back side intermediate region and leaf basin side into, Exhaust side edge is non-tangent switching fillet, is known as cutting R.When measured using routine R detection template the switching fillet of the structure, Since template and tenon mounting plate interfere, actually detected result is not consistent with true R value, testing result inaccuracy.

Summary of the invention

The purpose of the present invention is to overcome the above shortcomings and to provide a kind of non-tangent switching fillets of precision forged blade to detect cam group Part and measurement method can accurately measure precision forged blade tenon mounting plate and the non-tangent switching fillet in blade type face, improve life Produce efficiency.

In order to achieve the above object, a kind of non-tangent switching fillet of precision forged blade detects template component, including several detections Template, detection template form overall structure by department of assembly and measurement portion, and all detection templates are hinged by department of assembly, The head of measurement portion is a quarter cambered surface, and the radius of the cambered surface of each detection template is different, the head of measurement portion be used for Measure face contact.

The width of department of assembly is greater than measurement portion, seamlessly transits between department of assembly and measurement portion.

The cambered surface radius equal difference for detecting template is incremented by.

Detection template shares 21.

It detects and is offered in the department of assembly of template for the centre bore that all detection templates are hinged.

Bolt is inserted into centre bore, all detection templates are hinged on bolt by attaching nut.

Detect the marker being provided in the department of assembly of template for marking cambered surface radius R.

It detects template and uses CrWMn steel, hardness is HRC56~64.

A kind of measurement method of the non-tangent switching fillet detection template component of precision forged blade, comprising the following steps:

Step 1 chooses multiple detection templates according to the radius R at tenon mounting plate and blade switching；

Step 2 is bonded at tenon mounting plate and blade switching using the cambered surface of detection template one by one；

Step 3, the detection template that selection matches with the radius R at tenon mounting plate and blade switching, the detection template Cambered surface radius be then radius R at tenon mounting plate and blade switching.

In step 1, the radius R at tenon mounting plate and blade switching is estimated in range estimation first, then is chosen and met tenon installation Multiple detection templates of radius R at plate and blade switching.

Compared with prior art, detection template of the invention has multiple, and the cambered surface radius of each detection template measurement portion is equal Difference can detect the radian value of measuring surface by cambered surface and measurement face contact；Versatility of the present invention is good, at precision forged blade end It is swaged into shape and any process of machining process can measure precision forged blade tenon mounting plate and non-tangent turn of blade type face thereafter Fillet is connect, finds precision forged blade rejected product in time, to improve mold design and repairing die, improves non-tangent switching fillet Quality improves product qualification rate, reduces production cost, and the configuration of the present invention is simple, measurement is convenient, efficient, is suitable for precision forged blade Produce in enormous quantities.

Further, the present invention can be hinged on bolt by centre bore, can be more convenient in measurement It uses.

Further, the present invention has the marker of mark radius R, can quickly determine tenon mounting plate and blade type face Non- tangent switching fillet cuts R.

Method of the invention chooses multiple detection templates, due to every according to the radius R at tenon mounting plate and blade switching The radius of the cambered surface of a detection template measurement portion is different, therefore can measure precision forged blade tenon mounting plate and blade type face phase It cuts that switching fillet result is more accurate, and measurement error is small, is suitable for detecting precision forged blade tenon mounting plate and leaf in various situations Switching fillet is mutually cut in body type face, improves non-tangent switching radius quality, improves product qualification rate.
