Description
Technical field
The present invention relates to the processing tool detection fields of turbine blade, specially a kind of for detecting steam turbine circular arc tenon
The plug of tooth blade processing tooling.
Background technique
Fig. 1 is the mandrel structure for being traditionally used for detection steam turbine arc tenon-tooth vane jigs and ranging comprising core
Stick blade root 5 and plug stick core 6, plug blade root 5 simulate the arc tenon-tooth blade-root structure of blade, and plug stick core 6 is cylindrical structure.But
The plug of such structure has the following problems in processing, since plug blade root is arc tenon-tooth blade-root, it is necessary to use numerical control mill
The method cut processes it, and this requires add man-hour requirement first to carry out positioning and clamping to plug stick core.Due to plug stick
Core is cylindrical structure, and the common clamping mode that positions is to clamp plug stick core using upper and lower two V-blocks to position, such as Fig. 2 institute
Show, the two sides of lower section V-block 7 are respectively positioning surface, and the two sides of top V-block 8 are respectively seal face, and pressure direction is as schemed
In 2 shown in arrow.But after positioning, plug is easy to that the rotation around center line occurs in process, is difficult to realize accurate
Positioning and effective compression, cause plug blade root machining in the process there are large-scale dimension overproof, are not available so that scrapping,
Through counting, the qualification rate of plug processing is only 20%.
Summary of the invention
It is difficult in processing to core for the plug for being currently used for detection steam turbine arc tenon-tooth vane jigs and ranging
Stick core carries out accurately positioning and effectively compresses, and causes plug blade root size overproof on a large scale, plug passing rate of processing pole
Low technical problem, the present invention provides a kind of for detecting the plug of steam turbine arc tenon-tooth blade processing tooling, can mention
The qualification rate of machining accuracy and the plug processing of high plug blade root.
Its technical solution is such that a kind of for detecting the plug of steam turbine arc tenon-tooth blade processing tooling, packet
Plug blade root and plug stick core are included, the plug blade root is consistent with the structure of the arc tenon-tooth blade-root of blade, it is characterised in that: institute
It states plug stick core and includes coaxial sequentially connected locating piece one, cylindrical rod core and locating piece two, the locating piece one and the core
The raised head face of stick blade root connects, and the bottom surface of the locating piece one and the bottom surface of the locating piece two are coplanar and be that positioning is flat
Face, the top surface of the locating piece one and the top surface of the locating piece two are clamping plane.
It is further characterized by:
The positioning plane is parallel to the clamping plane.
The locating piece one is rectangular parallelepiped structure or cube structure.
The locating piece two is rectangular parallelepiped structure or cube structure.
The diameter of the cylindrical rod core is less than the vertical range between the positioning plane and the clamping plane.
The locating piece one, the cylindrical rod core and the locating piece two are integrally machined and are made.
The beneficial effects of the present invention are:
Mandrel structure of the invention, plug stick core coaxially sequentially connected locating piece one, cylindrical rod core and locating piece two, and
The bottom surface of locating piece one and the bottom surface of locating piece two are coplanar and be positioning plane, the top surface of locating piece one and the top of locating piece two
Face is clamping plane, and when processing plug blade root, the bottom surface of locating piece one and locating piece two can be used for positioning, and top surface can be used for
It compresses, to realize the accurate positionin and reliable compression to plug stick core, avoids rotating in plug process, Jin Erti
The qualification rate of the machining accuracy of high plug blade root, plug processing can be improved to 90% or more, greatly reduce rejection rate and plug system
Cause this.
Detailed description of the invention
Fig. 1 is the structural front view of traditional plug；
Positioning compression schematic diagram when Fig. 2 is traditional plug processing；
Fig. 3 is mandrel structure main view of the invention；
Fig. 4 is the right view of Fig. 3.
Specific embodiment
See Fig. 3 to Fig. 4, of the invention is a kind of for detecting the plug of steam turbine arc tenon-tooth blade processing tooling, wraps
Plug blade root 1 and plug stick core are included, plug blade root 1 is consistent with the structure of the arc tenon-tooth blade-root of blade, and plug stick core includes same
The sequentially connected locating piece 1 of axis, cylindrical rod core 3 and locating piece 24, it is preferred that locating piece 1, cylindrical rod core 3 and locating piece
24 are integrally machined and are made, and the integral rigidity of plug stick core can be improved；Locating piece 1 and the raised head face 11 of plug blade root 1 connect
It connects, the bottom surface 21 of locating piece one and the bottom surface 41 of locating piece two are coplanar and be positioning plane, the top surface 22 of locating piece one and fixed
The top surface 42 of position block two is clamping plane, it is preferred that positioning plane is parallel to clamping plane, so can be improved to plug stick core
Positioning compression effect.
For the ease of the processing of locating piece, locating piece 1 is rectangular parallelepiped structure or cube structure, and locating piece 24 is length
Cube structure or cube structure, the diameter of cylindrical rod core 3 are less than the vertical range between positioning plane and clamping plane, pass through
