The blade positioning and clamping device is characterized by comprising a blade root positioning and clamping device and a blade top positioning device, wherein the blade root positioning and clamping device and the blade top positioning device are fixed on the working platform of a processing machine tool in the length direction of a blade.
Description
Technical field
The present invention relates to the processing technique field of tenon tooth class blade-root molded line, be specially the blade positioning and clamping device for tenon-tooth blade-root processing.
Background technology
Mostly the processing of tenon tooth class blade root is for a long time to be located and clamped by square chest, it is inserted in square chest by 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, with square chest, realize the positioning and clamping of blade, thereby carry out the processing of tenon-tooth blade-root, see Fig. 1, in Fig. 1,15 is lathe workbench, 16 is square chest, 17 is tenon-tooth blade-root blade to be processed, its shortcoming is: it need to carry out separately the customization of square chest, make special-purpose square chest positioning fixture and make special-purpose sn-bi alloy, and sn-bi alloy can expansion cause deformable blade in cooling procedure, make 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 blade root tenon tooth process finishing, after leaf abscission square chest, need to remove prophyll top centre bore, and to take the blade root tenon tooth that processes be that base weight bores leaf top centre bore, also need in addition to process leaf top and clamp technique plane, its complex process, process costs 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, the leaf top of blade, because producing flutter phenomenon in cantilever position, causes the processing rigidity of blade lower, and finally affects the machining accuracy of tenon-tooth blade-root, thereby cause the repair rate of blade larger, working (machining) efficiency is low, and due to the density of the sn-bi alloy density much larger than common metal, therefore tradition adopts sn-bi alloy that blade and the method for square chest casting are located to clamping blade, and the bearing capacity of platen is increased, lathe shortening in service life.
Summary of the invention
For the problems referred to above, the invention provides the blade positioning and clamping device for tenon-tooth blade-root processing, it can effectively solve tradition and by sn-bi alloy and square chest location, clamp blade and carry out tenon-tooth blade-root and add the problem that process costs is high, production efficiency is low that exist 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 position positioning and clamping device and leaf top bit positioner, described blade root position positioning and clamping device and leaf top bit positioner are fixed on respectively the workbench of machining tool along the length direction of blade.
It is further characterized in that:
Described blade root position positioning and clamping device comprises base plate one, and longitudinal both ends of described base plate one are provided with L shaped positioning compression seat, and described two L shaped positioning compression seats are symmetrical installation longitudinally; The centre of the described two positioning compression seats on the lower flat of described two positioning compression seats and described base plate one is all provided with inner arc intermediate positioning support; The upper plane of described two positioning compression seats is all provided with moving press plate; On the upper inner wall of two described L shaped positioning compression seats, one of them is provided with location gradient piece, and another is provided with and compresses gradient piece, described location gradient piece and the inclined working angle and the tenon-tooth blade-root angle automatching that compress gradient piece; The lateral outer side wall of described two L shaped positioning compression seats is provided with blade root bottom surface locating piece; On described base plate one, the horizontal medial extremity of described two L shaped positioning compression seats is provided with the panel seat that baroclines, described in barocline on panel seat inclined plate be installed;
Described leaf top bit positioner comprises base plate two, on described base plate two, dead head is installed, and is provided with top on described dead head;
Described base plate one is provided with positioning key with base plate Er bottom surface, on the workbench of described machining tool, has keyway, and described base plate one is installed in described keyway with the positioning key of base plate two bottom surfaces.
Adopt blade positioning and clamping device of the present invention for the processing of tenon-tooth blade-root, its beneficial effect is: it no longer needs to use square chest to set up transition baseline, therefore it has reduced the customization of square chest, the processing steps such as casting of sn-bi alloy between square chest and blade, also effectively avoided the deformable blade causing because of the expansion of sn-bi alloy in cooling procedure simultaneously, and saved blade root tenon tooth process finishing, after leaf abscission square chest, remove prophyll top centre bore, and to take the blade root tenon tooth that processes be that base weight bores leaf top centre bore, and process leaf and push up manufacturing procedures such as clamping technique plane, it has simplified procedure of processing greatly, shortened process, reduced production cost, improved production efficiency, in addition, owing to having increased leaf top bit positioner, make the leaf top of blade divide the location that has also participated in blade to clamp, in blade root machining process, avoided the flutter phenomenon producing in cantilever position because of leaf top, improved the processing rigidity of blade, also improved the machining accuracy of tenon-tooth blade-root, reduced blade repair rate, improved working (machining) efficiency simultaneously, in addition, owing to no longer adopting the sn-bi alloy that density is larger to water casting blade and square chest, thereby greatly alleviate the bearing capacity of platen, play the effect in effective prolongation lathe life-span.
