Summary of the invention
The object of the present invention is to provide a kind of wheel hub turning power chuck, to significantly reducing the overall weight of the wheel hub turning power chuck of prior art, and then reduce machine tool chief axis load, extend overhaul life and the length of service of lathe, improve the utilization rate of lathe, meanwhile, improve the speed of mainshaft further, shorten the process time of each wheel hub, enhance productivity.
Above-mentioned purpose of the present invention is achieved in that provides a kind of wheel hub turning power chuck, it comprises chassis 2, upper plate 7, support ring 5, support guide rod 3, paw compresses link 1, centralized positioning frame 4, axial compression mechanism 13, radial automatic positioning mechanism 6, driving cylinder connecting axle 14, spring 10, chassis 2 is connected with lathe spindle, be fastenedly connected with chassis below support ring, be fastenedly connected with upper plate above support ring, support guide rod 3 is installed between chassis and upper plate, between upper plate and chassis, centralized positioning frame 4 is installed from top to bottom, paw compresses link 1, drive paw to compress link 1 by driving cylinder by driving cylinder connecting axle 14 to move down, thus driving axial hold-down mechanism 13 action compresses wheel hub, centralized positioning frame is promoted to move down by spring 10, drive the radial tensioner wheel hub of coupled radial automatic positioning mechanism 6, it is characterized in that: described support ring 5 is ring-type cone barrel, this support ring has a large end face, a small end face, large end face and upper plate 7 are fastenedly connected, small end face and chassis 2 are fastenedly connected, large end face center overlaps with upper plate center line and center chassis line with the small end face line of centres, this support ring can be annular taper tubular, also polygonal prism cone barrel circlewise can be done, as done polygonal prism cone barrel circlewise, its large end face and small end face are the regular polygon being greater than 3.
In one embodiment, chassis 2 and support ring 5 are made an entirety.
Adopt wheel hub turning power chuck of the present invention, there is effect useful as follows:
First, compressive load can be delivered on chassis by the supporting construction of this wheel hub turning power chuck effectively, under the prerequisite meeting chuck processing rigidity, not only can make support ring wall thickness reduction, but also can by upper plate wall thickness reduction, calculate by analysis, the weight of prior art power chuck can be reduced 35% to 45%, significantly alleviate the weight of wheel hub turning power chuck, just reduce the load of machine tool chief axis, reduce the energy resource consumption of spindle motor, just improve the service life of machine tool mainshaft bearing, thus extend overhaul life and the length of service of lathe, improve the utilization rate of lathe.Moreover, because main shaft load is reduced, so can further improve the speed of mainshaft, thus shorten the process time of each wheel hub, enhance productivity.Meanwhile, owing to improve the rotating speed of main shaft, the surface smoothness of wheel hub just can be improved, and surface quality just can be promoted.
Below in conjunction with drawings and Examples, wheel hub turning power chuck of the present invention is described further.
