Description
Technical field
It is specially a kind of for detecting steam turbine circle the utility model relates to the processing tool detection field of turbine blade
The plug of arc tenon tooth blade processing tool.
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 utility model provide it is a kind of for detecting the plug of steam turbine arc tenon-tooth blade processing tooling,
The machining accuracy of plug blade root and the qualification rate of plug processing can be improved.
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 utility model are:
The mandrel structure of the utility model, coaxially sequentially connected locating piece one, cylindrical rod core and the positioning of plug stick core
Block 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 fixed
The top surface of position block two 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,
Top surface can be used for compressing, to realize the accurate positionin and reliable compression to plug stick core, avoid occurring in plug process
Rotation, and then the machining accuracy of plug blade root is improved, the qualification rate of plug processing can be improved to 90% or more, greatly reduce useless
Product rate and plug manufacturing cost.
