Description
Technical field
The invention belongs to measuring device technical fields, and in particular to a kind of engine blade measuring device is sent out for aviation
Intake and exhaust side position is measured on motivation compressor high pressure rotor blade.
Background technique
Currently, the final machine-shaping of aviation high pressure rotor precision forged blade blade, intake and exhaust side and tenon be there are surplus, into
The processing on exhaust side is the emphasis of entire blade processing, and the processing on intake and exhaust side directly influences blade profile profile tolerance.It is conventional into
Exhaust side measuring tool carries out the clamping that force realizes tenon by the bottom surface to tenon, and the size of pressing force will affect blade in height
Position on direction, and the entire edge shape in intake and exhaust side belongs to space curve structure, the swing of short transverse will affect intake and exhaust
Edge causes to measure unstable to the distance of long-pending folded axle, and duplicate measurements consistency is poor, to influence the processing matter of entire blade
Amount.
Summary of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of engine blade measuring devices, by reasonable
Structure design, it is more precisely easy to control to the tenon applied force of blade, while ensure that the concordant docking of tenon bottom surface, avoid blade
It swings in the height direction, and then promotes measurement stability, to the precise and stable measurement in blade intake and exhaust side position, and have
There is preferable duplicate measurements consistency.
To achieve the goals above, the technical solution adopted by the present invention is that, a kind of engine blade measuring device, including leaf
Piece tenon clamp system, blade tenon clamp system include pedestal and the locating piece and compact heap that are oppositely arranged on pedestal,
Wherein, it is fixedly connected between locating piece and pedestal, compact heap can translate on pedestal, and the locating piece one side opposite with compact heap is equal
It is provided with force surface corresponding with the pressure face of blade tenon；By compact heap to the mobile realization of locating piece to the folder of blade tenon
Tightly.
It further include the supporting block being arranged between locating piece and compact heap, the top surface of supporting block and the bottom surface of blade tenon are pasted
It closes.
When the top surface of the bottom surface of blade tenon and supporting block contacts, the force surface of locating piece and compact heap is not fastened on leaf
The most narrow place of piece tenon.
Locating piece is identical as the structure of compact heap, and locating piece and compact heap convex to form force surface oppositely facing interior stretching,
The cooperation of the pressure face of force surface and blade tenon.
Further include the bearing support being set on the base, be provided with hold-down mechanism on bearing support, bearing support and hold-down mechanism it
Between be threadedly coupled, hold-down mechanism one end is provided with adjusting knob, and other end is connected on compact heap.
Connected between hold-down mechanism and compact heap by bearing, the outer ring of bearing is fixed on hold-down mechanism, bearing it is interior
Circle is connect with hold-down mechanism.
It further include the track being set on the base, compact heap, which is fastened on track, to be slided along track, and the one of hold-down mechanism
End is against on compact heap.
Hold-down mechanism is threaded rod.
Compared with prior art, the present invention at least has the advantages that, by the way that locating piece and pressure are arranged on pedestal
Tight block, the movement between, which can be realized effectively, positions the pressure face of blade tenon, is positioned with tenon pressure at both sides face,
Bottom surface compresses in a manner of inverted triangle, and regardless of pressing force, blade type face will be all in a fixed position on the basis of tenon, this
Sample can accurately measure out intake and exhaust side position dimension, guarantee duplicate measurements consistency, significant effect；It is measured in process control
As a result consistent with three-dimensional coordinates measurement result, economic benefit is obvious, and the measuring device is compact structure and easy to use, and maintenance is simple.
Further, locating piece or compact heap and force surface thereon are structure as a whole design, performance stabilization.
Further, using the hold-down mechanism of threaded connection, the adjusting of path increment is carried out by adjusting knob, it is more smart
It is quasi- easy to control.
Further, it is connected as one between hold-down mechanism and compact heap by bearing, facilitates operation.
Further, compact heap passes through the track being set on the base and is slided, and can be realized the mobile essence of compact heap
Really control, and can have degree of precision after long-time use.
Detailed description of the invention
Fig. 1 is blade tenon clamp system schematic diagram of the invention:
In attached drawing: 1 blade tenon, 2 locating pieces, 3 support frames, 4 compact heaps, 5 hold-down mechanisms, 6 pedestals, 7 supporting blocks.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the present invention includes pedestal 6 and the locating piece being oppositely arranged on pedestal 62 and compact heap 4,
In, be fixedly connected between locating piece 2 and pedestal 6, compact heap 4 can translate on pedestal 6, locating piece 2 it is opposite with compact heap 4 one
Face is provided with force surface corresponding with the pressure face of blade tenon 1, and locating piece 2 is identical as the structure of compact heap 4, force surface with
The pressure face of blade tenon 1 cooperates；It further include the supporting block 7 being arranged between locating piece 2 and compact heap 4, the top surface of supporting block 7
It is bonded with the bottom surface of blade tenon 1；In addition, locating piece 2 and compact heap 4 convex to form force surface oppositely facing interior stretching, and
When the top surface of the bottom surface of blade tenon 1 and supporting block 7 contacts, the force surface of locating piece 2 and compact heap 4 is not fastened on blade tenon
First 1 most narrow place；
Further include the bearing support 3 being set on the base, hold-down mechanism 5, bearing support 3 and compacting machine are provided on bearing support 3
It is threadedly coupled between structure 5, and hold-down mechanism one end is provided with adjusting knob, other end is connected on compact heap 4；
In a certain embodiment of the invention, connected between hold-down mechanism 5 and compact heap 4 by bearing, the outer ring of bearing
It is fixed on hold-down mechanism 5, the inner ring of bearing is connect with hold-down mechanism 5；
It in another embodiment of the invention, further include the track being arranged on pedestal 6, compact heap 4 is arranged in orbit,
One end of hold-down mechanism 5 is against on compact heap 4.
The mode that is exerted a force to the pressure face of blade tenon present invention employs compact heap and locating piece realizes blade
Tenon is fixedly clamped, it is contemplated that the triangular structure of blade tenon does not upwards exert a force to blade tenon bottom surface using bottom
The fixation of blade tenon is carried out, reason is during the force of bottom exist between tenon and locating piece and compact heap certain
Spacious amount will lead to the inaccuracy of measurement result, and it is consistent to influence duplicate measurements at this time if tenon waves appearance
Property, and then influence whether the processing of entire blade, and use to cooperate between locating piece and compact heap and tenon pressure face is applied
Power can be effectively solved this problem.
