Description
Technical field
The utility model relates to a kind of clamp fixture, and a kind of length adjustable turbine Blade Machining fixture, belongs to fixture equipment technology field specifically.
Background technology
Blade is one of critical component of steam turbine, the motion of the good bad influence air-flow of its steam passage part molded line. determine the generating efficiency of steam turbine, directly have influence on the quality of steam turbine product, also the working effect of blade is directly affected, and then directly affect the service behaviour of complete machine, so the processing of blade steam passage part is most important, the requirement for molded line is more strict.
Blade processing both domestic and external is all adopt Digit Control Machine Tool to process a few days ago, processing method is also different, the frock clamp used is also more diversified, we adopted the frock of machine vice and designed, designed with the use of processing in the past, conventional fixture is all generally special tooling, just different fixtures is needed to carry out adaptation dimensions is different when processing the blade of same model, cumbersome for processor, affect working (machining) efficiency.
Utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, there is provided a kind of length adjustable turbine Blade Machining fixture, overcoming existingly just needs to change the shortcoming of fixture art because of size difference, realizes the general of fixture and improves the object of working (machining) efficiency.
In order to solve above technical problem, the utility model provides a kind of length adjustable turbine Blade Machining fixture, comprise base and the clamp body being arranged on base two ends, described clamp body comprises end of blade fixture and blade root fixture, described blade root fixture comprises two blade root fixture blocks and the blade root base plate for being connected two blade root fixture blocks, described blade root base plate is fixedly linked by connecting bolt and described base
Described end of blade fixture comprises end of blade base plate and is arranged on two end of blade fixture blocks on described end of blade base plate, described end of blade base plate is fixedly linked by bolt and described base, the end of blade base plate of described end of blade fixture block lower end is provided with U-shaped locating slot, slidably T-shaped screw is provided with in described U-shaped locating slot, described end of blade fixture block is provided with the fixed installation hole be socketed on described T-shaped screw, is fixedly mounted on described end of blade base plate by nut by described end of blade fixture block;
The side of described blade root fixture block and end of blade fixture block is provided with the fixing hole perpendicular to blade to be processed, is provided with the set bolt of fastening blade to be processed in described fixing hole.
The technical scheme that the utility model limits further is: aforesaid length adjustable turbine Blade Machining fixture, the U-shaped locating slot side of described end of blade base plate is also provided with U-shaped gathering sill, the guide pad that the bottom that described U-shaped gathering sill is built-in with end of blade fixture block has.
Aforesaid length adjustable turbine Blade Machining fixture, the base between described end of blade fixture and blade root fixture is provided with alignment pin, in order to locating blades, ensures that blade is in horizontal machining position.
Further, aforesaid length adjustable turbine Blade Machining fixture, is connected by welding manner between the blade root base plate of described blade root fixture block.
The beneficial effects of the utility model are: the utility model structure is simple, cost is low, can according to simple structure, by realizing the blade that fixture can adapt to different length to the adjustment of end of blade fixture block position, that guarantees to add man-hour can put into clamp for machining completely, ensure the precision adding man-hour, processing for similar vanes in enormous quantities effectively can shorten process time, increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structure top view of the present utility model.
