Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is the structural representation that the present invention assembles with workpiece.
Detailed description of the invention
See Fig. 1, 2, a kind of disk six-hole ball-cage constant velocity universal joint shell impewdance matching frock, include base 1 and seal disc 2, the bottom of base 1 has the staight shank 4 being connected installation with quenching machine, seal disc 2 is fixedly mounted on base 1, and lower section at seal disc 2 is provided with cavity 5 on base 1, the through hole 6 being connected with cavity 5 it is provided with in staight shank 4, seal disc 2 is provided with the counterbore 7 for positioning workpiece 10, surrounding around counterbore 7 has been respectively fixedly connected with six water jet columns 3, the blind hole 8 being connected with cavity 5 it is respectively equipped with in six water jet columns 3, hole for water spraying 9 that is densely covered and that be connected it is respectively equipped with blind hole 8 on the madial wall of six water jet columns 3.
