It stands in 10 threaded hole of block in face；The hold-down mechanism includes cushion block bolt 5, studs 6 and pressing plate 12, and the studs 6 revolves
Into bottom plate 1, cushion block bolt 5 is located on the bottom of studs 6, bottom plate 1, and pressing plate 12 is located at 6 top of studs, pressure
Plate 12 is adjustable above and below the position on studs 6；The hold-down mechanism is three, is distributed in by three cylindrical support blocks, is used
In pushing down the false boss on knuckle, specific location is adjustable, according to workpiece pressing pressure point position and does not interfere and is processed as principle
Select its position distribution.
Further, the first cylindrical support block 4, the second cylindrical support block 9 and third cylindrical support block 13 are logical
M16 bolt is crossed to be fixed on bottom plate 1.
Further, the jackscrew 8 is threaded in vertical 10 threaded hole of block in side by M10 nut 7.
Further, the cushion block bolt 5 is threadedly coupled by M16 nut 11 with studs 6 with pressing plate 12.
Compared with prior art, as follows the advantages of the utility model:
The tooling of the utility model solve the problems, such as in spindle trial-manufacturing process can not quick positioning and clamping, pass through
Knuckle can be quickly positioned using tooling described in the utility model, improves processing efficiency, and easy to operate, accuracy is high, at
This is extremely low.
Detailed description of the invention
Fig. 1 is a kind of clamping of knuckle of the utility model and the Structure explosion diagram of positioning tool；
Fig. 2 is a kind of clamping of knuckle of the utility model and the installation diagram of positioning tool；
In figure: bottom plate 1, spring 2, spiral cambered surface center bridge 3, the first cylindrical support block 4, cushion block bolt 5, studs 6,
Block 10, M16 nut 11, pressing plate 12, third cylindrical support block 13 are found in M10 nut 7, jackscrew 8, the second cylindrical support block 9, side.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Embodiment 1
A kind of clamping and positioning tool of knuckle, including bottom plate 1, spiral cambered surface center bridge 3, the first cylindrical support block 4,
Second cylindrical support block 9, third cylindrical support block 13 and hold-down mechanism；Wherein, the first cylindrical support block 4, second circle
Column supporting block 9 and third cylindrical support block 13 are fixed on bottom plate 1, for leveling up knuckle；The first cylindrical support block 4,
The height of the height fall of second cylindrical support block 9 and third cylindrical support block 13 three false boss corresponding on knuckle
It is identical to spend drop, the spiral cambered surface center bridge 3 is fixed in the counterbore on bottom plate 1 by spring 2；The bottom plate 1 is also set up
There is side to found block 10, be located at by knuckle Y-direction positioning process boss, side stands and is provided with threaded hole on block 10, and jackscrew 8 is threaded to side
It stands in 10 threaded hole of block in face；The hold-down mechanism includes cushion block bolt 5, studs 6 and pressing plate 12, and the studs 6 revolves
Into bottom plate 1, cushion block bolt 5 is located on the bottom of studs 6, bottom plate 1, and pressing plate 12 is located at 6 top of studs, pressure
Plate 12 is adjustable above and below the position on studs 6；The hold-down mechanism is three, is distributed in by three cylindrical support blocks, is used
In pushing down the false boss on knuckle, specific location is adjustable, according to workpiece pressing pressure point position and does not interfere and is processed as principle
Select its position distribution.
Further, the first cylindrical support block 4, the second cylindrical support block 9 and third cylindrical support block 13 are logical
M16 bolt is crossed to be fixed on bottom plate 1.
Further, the jackscrew 8 is threaded in vertical 10 threaded hole of block in side by M10 nut 7.
Further, the cushion block bolt 5 is threadedly coupled by M16 nut 11 with studs 6 with pressing plate 12.
When specifically used, the first cylindrical support block 4, the second cylindrical support block 9 and third cylindrical support block 13 are torqued-up to
On bottom plate 1, three cylindrical support block height are inconsistent, have relative fall, the technique that height relative fall corresponds to knuckle
Boss ordinate height fall.Spring 2 and spiral cambered surface center bridge 3 are successively fallen in the counterbore of bottom plate 1, spiral cambered surface centering
Block 3 has the compressible height of 5mm in Z-direction；Block 10 is found in side to be torqued-up on bottom plate 1, jackscrew 8 is threaded to side and founds 10 screw thread of block
Kong Zhong, then nut 7 is torqued-up on jackscrew 8, prevent jackscrew 8 from falling off.Studs 6 is threaded in bottom plate, by cushion block bolt 5 with
Pressing plate 12 is threadedly coupled by M16, pressing device is formed, it is required that pressing plate bottom level is held with false boss on knuckle
It is flat.Fixture is put up substantially.By knuckle drive shaft avoid holes be aligned spiral cambered surface center bridge, limited at this time knuckle X,
Y-direction freedom degree, compresses knuckle down, and three false boss are aligned three cylindrical support block upper surfaces, level up knuckle,
The rotary freedom for limiting two directions of Z-direction freedom degree and X, Y, screwing the contact of jackscrew 8 knuckle side, (initial workpiece needs to rotate
Jackscrew, subsequent not have to), knuckle Z-direction freedom degree is limited, so far positioning is completed in knuckle, and pressing plate 12 is depressed on knuckle
False boss screws M16 nut 11, knuckle is compressed, and so far completes positioning and the clamping of knuckle.
