It is circumferentially with the chuck seam allowance of upward bias on the right side of disk, three-jaw self-centering chuck bottom is fixedly connected with by the chuck seam allowance,
The central shaft of the chuck seam allowance and the center overlapping of axles of three-jaw self-centering chuck, the positioning support L-shaped structure, and one
Side is fixedly connected on the upper surface of three-jaw self-centering chuck, is vertically installed with positioning bolt on the other side, on the positioning bolt
It is connected with hex-head nut.
Further, it is connected with balance weight iron at the one side edge of the fixed disk far from three-jaw self-centering chuck.
Further, the fixed disk Left-side center is equipped with cylinder shape groove, and outward opening, is surrounded on the fixed disk
Multiple fixed holes are uniformly provided at cylinder shape groove circumferential edge, the cylinder shape groove is connect with lathe headstock, and is passed through
Bolt in fixed hole is fixed, and the middle and upper part of the fixed disk is uniformly provided with multiple three-jaw self-centering chuck connections
Hole, the fixed disk connect three jaw self-centering cards by the first hexagon socket countersunk flat cap head screw in three-jaw self-centering chuck connecting hole
The lower part of disk, the fixed disk is uniformly provided with multiple balance weight iron connecting holes, and the fixed disk passes through in balance weight iron connecting hole
Two hexagon socket countersunk flat cap head screws connect balance weight iron.
Further, the side that the positioning support is connect with three-jaw self-centering chuck passes through hexagonal countersunk head in two thirds
Screw is fixedly connected on the upper surface of three-jaw self-centering chuck.
Compared with the existing technology, the fixture of the present invention for vehicle bias one-throw crankshaft has the advantage that：
(1) fixture of the present invention for vehicle bias one-throw crankshaft on fixed disk by being arranged eccentric chuck seam allowance
It is directly fixedly connected with three-jaw self-centering chuck bottom, by crankshaft installed to be processed when on three-jaw self-centering chuck, directly makes
The point to be processed of bent axle to be processed is in eccentric state, while also avoiding fixing between disk and three-jaw self-centering chuck when rotated
The relative movement phenomenon being likely to occur, bent axle to be processed is clamped using the self-centering action of three-jaw self-centering chuck, and lead to
The positioning bolt crossed in positioning support adjust bent axle to be processed part to be processed make its perpendicular to fixed disk axis and three-jaw from
Centering chuck axis, meanwhile, prevent its moving in rotation using positioning support fixed crankshaft；The device is installed on lathe headstock
And after adjusting positioning, eccentric one-throw crankshaft can be produced in enormous quantities, adjusted again again without one bent axle to be processed of every installation
Whole device positioning.
(2) balance weight iron is arranged on fixed disk in the fixture of the present invention for vehicle bias one-throw crankshaft, avoids partially
The heart acts on, and ensure that balance rotating.
