Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As it can be seen, turbine blade five axle essence profile universal fixturing, adjust element and fixture including fixture setting element, fixture Clamping element;
Fixture setting element is made up of clamp body, thimble seat, and with soket head cap screw fixation clamp, concrete and thimble seat, comes with alignment pin The clamp body of positioning belt taper shank and concentric thimble seat, make clamp body and thimble seat keep with one heart.The square toes of thimble seat both sides are tight Determine screw and can be used for the fine setting to thimble;It is then positioned on lathe, makes the center of thimble and the center superposition of lathe.Described folder Tool setting element is by making by oneselfAlignment pin 1, clamp body 7, taper shank connecting hole 8, locating groove 9,Clamp body dowel hole 10, thimble seat 13, thimble seatHole 19, dowel hole 14, square toes holding screw 16, thimble 17, thimble seat location is constituted, First thimble 17 is put in the hole 19, thimble seat location of thimble seat 13, front and back fix, then with self-controlAlignment pin 1 Locating clip is concreteDowel hole 10 and thimble seatDowel hole 14, makes center and the taper shank of clamp body 7 of thimble 17 Center superposition, be screwed.Can enter in the both sides of thimble seat 13 with square toes holding screw 16 if having slight deviations Row fine setting.Then locating piece locating groove 9 being directed on lathe, connects with taper shank connecting hole 8 and lathe, it is ensured that fixture Thimble and lathe are concentric, finally tighten and just complete located.
Described fixture adjusts element by jaw 2, T-shaped slide block 3, left slider 4, double end acme thread bolt 5, right slide block 6, fixture Body T-slot 11, slide block T-slot 12 are constituted, and first left slider 4 are connected with of double end acme thread bolt 5, and then one Rise put in clamp body T-slot 11, righter slide block 6 is also placed in clamp body T-slot 11 and with double end acme thread bolt 5 Other end connect.Motion thread finally by double end acme thread bolt 5 can be achieved with moving up and down of fixture;Two T-shaped slide block 3 is respectively put in the slide block T-slot 12 of left slider 4 and right slide block 6, then profile of tooth and the left slider of jaw 2 4, the profile of tooth occlusion of right slide block 6, tightens, by jaw 2, the T-shaped slide block 3 being placed in slide block T-slot 12 with soket head cap screw, Fix jaw 2 and left slider 4, right slide block 6, thus can be adjusted the model of fixture by the movement of T-shaped slide block 3 and profile of tooth Enclose, simple to operate, and also the occlusion of profile of tooth is not easy to slide.
Left slider, right slide block and jaw are all with profile of tooth, and two jaws pass through two T-shaped slide blocks respectively at left slider and right slide block Connect, realize adjusting up and down by the movement of T-shaped slide block and profile of tooth.
Described clamp pressing element is by left slider 4, double end acme thread bolt 5, right slide block 6 and thimble seat 13, end face locating piece 15, thimble 17, spring 18, hole 19, thimble seat location are constituted, first a company of left slider 4 with double end acme thread bolt 5 Connect, put into the most together in clamp body T-slot 11, righter slide block 6 is also placed in clamp body T-slot 11 and terraced with double end The other end of type screwed plug 5 connects.Blade pulls the hexagon socket head at double end acme thread bolt 5 two with inner hexagon spanner after having good positioning, Blade is compressed the most permissible.
Spring 18 is put in hole 19, thimble seat location, then thimble 17 is also placed in hole 19, thimble seat location, with fluting Sunk screw is connected end face locating piece 15 with thimble seat 13, fixes thimble 17 and holds out against spring 18, by the pressure of spring 18 Clamp force compresses thimble 17.
During use, first thimble 17 is placed on after thimble seat 13 fixes with self-controlAlignment pin 1 is positioned at clamp body Dowel hole 10 and thimble seatIn dowel hole 14, make the center of thimble 17 and the center superposition of the taper shank of clamp body 7, It is contained in after fixing on lathe, it is ensured that the center of fixture thimble and the center superposition of lathe.Then pass through double end acme thread bolt 5 With left slider 4, right slide block 6 adjust the distance between two jaws 2, if distance is the most not, can be by adjusting T Type slide block 3 and profile of tooth expand the distance between two jaws 2.Qualified blade 20 is put between jaw 2, uses thimble 17 withstand blade 17, and pulling double end acme thread bolt 5 with inner hexagon spanner after fixing, to make jaw 2 clamp blade 20 the most permissible.
The above is only preferred implementation of the present utility model, it should be pointed out that: for those skilled in the art For, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications are also Should be regarded as protection domain of the present utility model.
