The specific embodiment
Described clamp structure for lathe comprises first pawl 2, second pawl 4 and the three-jaw 6, and, the inner of first pawl 2, second pawl 4 and three-jaw 6 is pointed to the clamping center of clamp structure respectively, the inner at first pawl 2, second pawl 4 and three-jaw 6 is provided with hard nail 5 respectively, and this follows closely the clamping face 15 that 5 clamping head 13 protrudes in claw firmly.
Because nail 5 is loaded on the design of claw inside firmly, former claw galianconism supporting workpiece changes into by hard nail 5 supporting workpieces, and the claw galianconism defective of wearing and tearing easily is eliminated, and this risk is born by hard nail 5, and this has just improved the service life of claw.
Each claw forms L shaped by the arm 9 of drawing money on credit with short support arm 8; The short support arm 8 of each claw lays respectively at the inner of claw, and the arm 9 of drawing money on credit of each claw evenly distributes in the concentric circles that with the clamping center is the center of circle radially; End away from the arm 9 of drawing money on credit on short support arm 8 is a bare terminal end 14, and the side away from the center of clamping on bare terminal end 14 is a clamping face 15, and described hard nail 5 is arranged on the bare terminal end 14 of short support arm 8.This split type claw can be used for endoporus location workpiece, and claw adopts split type structural design, has easy manufacturing, the advantage of being convenient to install.
End face at the bare terminal end 14 of first pawl 2 and second pawl 4 is provided with claw catch 3.Claw and claw catch were arranged in 3 minutes, and claw catch 3 can be changed, and had eliminated the risk of former claw fission, the service life of having improved claw.Changed locate mode simultaneously, by the step of inside active force on original three split type claws, be altered to the claw catch 3 of two inside active forces, another locating shim 7 by outside active force determines that this kind locate mode is more reasonable, the positioning accuracy height.
One end of hard nail 5 is a clamping head 13, and the other end is provided for and will follows closely 5 screws 12 that are installed on the claw firmly.The particular design of hard nail 5, the replacing after not only being convenient to wear and tear, and also maintenance cost is also low.Between hard nail 5 and the claw also can be non-removable fixedlying connected, as welding or riveted joint etc.Preferably adopt dismountable fixedly connectedly, advantage is to change more conveniently, and maintenance cost is low.On claw catch 3, be provided for claw catch 3 is installed on connecting hole 11 on the claw, so that the replacement of claw catch improves service life.Outer end at the arm 9 of drawing money on credit of described three-jaw 6 is provided with locating shim 7, changes into the locating shim 7 of an outside active force by the step of an inside active force, and locate mode is more reasonable, the positioning accuracy height.Also can dismountable general hard pawl replace block 16 be set, on general hard pawl replace block 16, locating shim 7 be set again in the outer end of the arm 9 of drawing money on credit of three-jaw 6.
The utility model proposes a kind of long service life at the defective of former claw, and the claw that positioning accuracy is high reaches by its machining fixture of forming.As mentioned above, the utility model main body constitutes with roughly the same originally, is made up of three split type claws, but very big difference is arranged on concrete structure.Three claw profile differences, hard nail 5 all is housed on each claw, end at the bare terminal end 14 of lacking support arm 8 does not have original step, but installed claw catch 3 additional on the end face of two claw bare terminal ends 14 therein, this claw catch 3 is equivalent to step, be used for hooking the blank inner face of turbine case 1, follow closely 5 material employing bearing steel firmly, the hardness height.In the use, can be by changing hard nail 5 or/and change the service life that claw catch 3 prolongs claw, and also maintenance cost also reduces greatly.Wherein first pawl 2 is identical with the appearance and size of second pawl 4, and the structure difference of hard nail 5 and claw catch 3, the three-jaws 6 all is housed, see Fig. 3, locating shim 7 on the three-jaw 6 is not at the claw outward flange, but on the right-angle plane of claw, locating shim 7 is used for propping up the inlet flange limit of turbine case.
If on three-jaw 6, do a little change, can also further enlarge the scope of application of this claw, can be applicable to the volute (as shown in Figure 7) of the more kinds of processing.
The another kind of structure of three-jaw 6 such as Fig. 7, shown in Figure 8, three-jaw 6 is made two-part stack, the part that is partitioned on the three-jaw 6 (being called general hard pawl replace block 16 temporarily) as shown in Figure 9, general hard pawl replace block 16 usefulness bolts 17 are fastened on the three-jaw 6, so can increase the universal performance of claw.Only need in use to change general hard pawl replace block 16, just reach the purpose of changing claw, it is close to be suitable for blanking inner hole, all different workpiece of flange position height, particularly suitable when making in batches little workpiece wide in variety.
As shown in Figure 1: the utility model claw reaches and is applicable to lathe in machining turbine case 1 by its machining fixture of forming, claw and oild chuck are located with serration, be linked and packed with bolt, first pawl 2, second pawl 4 and three-jaw 6 are past overhanging under the effect of hydraulic power, three hard nails 5 of claw inside prop up F1, F2, F3 3 points of turbine case 1 blanking inner hole, to determine the shaft core position of turbine case 1; Claw catch 3 on first pawl 2 and second pawl 4 hooks Z1, Z2 2 points of the blank inner face of turbine case 1, and the locating shim 7 on the three-jaw 6 props up the Z3 point of turbine case 1 flange, determines another vertical plane position.The thickness that only need adjust locating shim 7 during debugging is adjusted the depth of parallelism of turbine case 1 blank inner face, can guarantee accurate positioning, and is more convenient.
The utility model equally also applicable to lathe in machining endoporus location class part such as inner face do sleeve part, the shape of blank location benchmark special with the support class part of interior circle and inner face location etc.
The utility model compared with prior art has very outstanding advantage:
1, because this is bound firmly in the design of claw inside, former claw galianconism supporting workpiece changes into by hard nail and supporting Workpiece, claw the galianconism easily defective of wearing and tearing are eliminated, and this risk is born by hard nail, firmly follows closely the hardness height, And nail can be replaced firmly, and this has just improved the service life of claw.
2, guaranteed hi-Fix of the present utility model because locate mode is different: the utility model adopts The endoporus dead axle heart, the claw catch 3 on first pawl 2 and second pawl 4 hook the inner face of turbine case Z1, Z2 2 points, the locating shim 7 on the three-jaw 6 props up the Z3 point of the flange of turbine case. This locate mode Can guarantee the positional precision of Z direction. Prior art then adopts presss from both sides the locate mode that cylindrical clamps the center surely, The position in definite X-Y plane only.
3, because the utility model adopts the thickness of adjusting the locating shim 7 between claw and the workpiece to determine to decide The position of bit plane. Thereby debugging is convenient, can reduce to a great extent debug time, carry out large quantities of The amount production and processing the time, can increase substantially working (machining) efficiency, reduce cost. Prior art then be by Shimming is adjusted the clamping center of claw between claw and chuck.
4, because the utility model arranges general hard pawl replace block in the outer end of the arm of drawing money on credit of three-jaw, in small batches Measure the effect that to play again the fast replacing frock in many kind processing.
