Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, axle sleeve grinding frock comprises locating shaft core 1, pull bar 2, positioning baffle 3, locking nut 4, bearing 6 and hydraulic cylinder 7.
As shown in Figure 2,3, the outer face of locating shaft core 1 centrally line arranges center positioning hole 8, and the radial direction of locating shaft core 1 arranges the pin shaft hole I 9 running through center positioning hole 8.Be arranged on by this locating shaft core 1 after in axle sleeve 14, the center positioning hole 8 on locating shaft core 1 outwardly.The cylindrical of locating shaft core 1 is in axial direction symmetrical arranged groove 12 near outer face, and groove 12 and pin shaft hole I 9 distribute in 90 degree in radial directions.Outer face 5 ~ the 10mm of pin shaft hole I 9 Distance positioning axle core 1; This distance both can ensure that locating shaft core 1 outer end had enough intensity, can not affect again this locating shaft core 1 and insert the degree of depth in axle sleeve 14, and then the pin shaft hole I 9 on locating shaft core 1 is positioned at outside the end face of axle sleeve 14.
