Description
Technical field
The present invention relates to the processing technique field of tenon tooth class blade root molded lines, be specially the blade positioning and clamping device that is used for the processing of tenon tooth blade root.
Background technology
Mostly the processing of tenon tooth class blade root for a long time is through the square chest location and clamps; It is inserted in square chest with blade; Between blade and square chest, pour into a mould sn-bi alloy; Thereby it is as a whole that blade is connected with square chest, thereby use square chest to realize that the location of blade and clamping carry out the processing of tenon tooth blade root, sees Fig. 1; 15 is that lathe workbench, 16 is that square chest, 17 is tenon tooth blade root blade to be processed among Fig. 1; Its shortcoming is: its need carry out separately square chest customization, make special-purpose square chest positioning fixture and make special-purpose sn-bi alloy, and sn-bi alloy can expand in cooling procedure and cause deformable blade, makes the blade root tenon tooth that processes and the relative position size of working position produce deflection; The particularly reference position of leaf top centre bore skew; This just causes behind blade root tenon tooth process finishing, the leaf abscission square chest needs to remove prophyll top centre bore and is that base weight bores leaf top centre bore with the blade root tenon tooth that processes, and also need process the leaf top in addition and clamp the technology plane, and its complex process, the technology cost is high, production efficiency is low; In addition, used the tight blade of square chest locating clip, in processing blade root process in the past; Vane top produces flutter phenomenon because of being in cantilever position, causes the processing of leaves rigidity lower, and finally influences the machining accuracy of tenon tooth blade root; Thereby cause the repair rate of blade bigger, working (machining) efficiency is low; And because the density of sn-bi alloy is much larger than the density of common metal, therefore tradition adopts sn-bi alloy that the blade and the method for square chest casting are located the clamping blade, makes the bearing capacity of platen increase, lathe shortening in service life.
Summary of the invention
To the problems referred to above; The invention provides the blade positioning and clamping device that is used for the processing of tenon tooth blade root; It can effectively solve tradition and clamp blade through sn-bi alloy and square chest location and carry out the tenon tooth blade root and add the problem that the technology cost is high, production efficiency is low that exists man-hour, and can effectively improve blade processing rigidity, prolongation lathe service life.
Its technical scheme is such; It is characterized in that: it comprises blade root spots localization clamping device and leaf top bit positioner, and said blade root spots localization clamping device and leaf top bit positioner are fixed in the workbench of machining tool respectively along the length direction of blade.
It is further characterized in that:
Said blade root spots localization clamping device comprises base plate one, and vertical both ends of said base plate one are equipped with L shaped location pressed seat, and said two L shaped location pressed seats vertically symmetry are installed; The centre of the said two location pressed seats on the lower flat of said two location pressed seats and the said base plate one all is equipped with inner arc intermediate positioning support; The upper plane of said two location pressed seats all is equipped with moving press plate; On the upper inner wall of described two L shaped location pressed seats, one of them is equipped with location gradient piece, and another is equipped with and compresses the gradient piece, said location gradient piece and inclined working angle that compresses the gradient piece and tenon tooth blade root angle coupling; The lateral outer side wall of said two L shaped location pressed seats is equipped with blade root bottom surface locating piece; On the said base plate one, the horizontal medial extremity of said two L shaped location pressed seats is equipped with the panel seat that baroclines, and on the said panel seat that baroclines inclined plate is installed;
Said leaf top bit positioner comprises base plate two, on the said base plate two dead head is installed, and is equipped with top on the said dead head;
Said base plate one is provided with positioning key with the bottom surface of base plate two, has keyway on the workbench of said machining tool, and said base plate one is installed in said keyway with the positioning key of base plate two bottom surfaces.
Adopt blade positioning and clamping device of the present invention to be used for the processing of tenon tooth blade root; Its beneficial effect is: it no longer need use square chest to set up transition baseline; Therefore it has reduced the processing steps such as casting of sn-bi alloy between customization, square chest and the blade of square chest; Also effectively avoided simultaneously the deformable blade that causes because of the expansion of sn-bi alloy in cooling procedure; And saved and removed prophyll top centre bore behind blade root tenon tooth process finishing, the leaf abscission square chest and be that base weight bores leaf top centre bore and processes the leaf top and clamps manufacturing procedures such as technology plane with the blade root tenon tooth that processes; It has been simplified procedure of processing, shortened process greatly, has reduced production cost, has improved production efficiency; In addition; Owing to increased leaf top bit positioner, the location that makes the vane top part also participate in blade clamps, and in the blade root process, has avoided being in the flutter phenomenon that cantilever position produces because of the leaf top; Improved the processing of leaves rigidity; Also improve simultaneously the machining accuracy of tenon tooth blade root, reduced the blade repair rate, improved working (machining) efficiency; In addition, owing to no longer adopt the bigger sn-bi alloy of density to water casting blade and square chest, thus alleviate the bearing capacity of platen greatly, play the effect in effective prolongation lathe life-span.
