Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8：It is a kind of to process consolidating for power transmission shaft yoke universal joint hole
Determine pedestal, including support base 1, connector 2, spline limit shaft 3 and fixing device 4, the connector 2 is located at the support bottom
Between seat 1 and the spline limit shaft 3, its upper end is connected with the lower surface fixed vertical of spline limit shaft 3, lower end and support
The upper surface fixed vertical connection of base 1, the fixing device 4 is located at the center of the upper end of spline limit shaft 3, with institute
State spline limit shaft 3 and fix welding, the fixing device 4 includes fastening screw 41, platen 42, gag lever post 43 and firm banking
44, the screw 441 being engaged with the structure of fastening screw 41 is provided with the center of the upper surface of firm banking 44, it is described
The both sides of screw 441 are symmetrically arranged with gag lever post 43, and the gag lever post 43 is connected with the fixed vertical of firm banking 44, described
