When the outer diameter of the annular support plate 52 is equal to the inner diameter of the shield 2, the outer wall of the annular support plate 52 is connected to the inner wall of the shield 2, so as to further improve the stability of the axial positioning member 5 during sliding.
A primary compression spring 6 mounted between the radial positioning element 4 and the annular support plate 52. The primary compression spring 6 is compressed to deform during relative sliding movement between the radial positioning element 4 and the annular support plate 52. More closely, because the second annular groove 43 has been seted up to the terminal surface of radial positioning element 4, a part of one-level compression spring 6 sets up in this second annular groove 43 to improve one-level compression spring 6 installation stability, prevented that it from producing radial displacement, the groove depth direction of second annular groove 43 has also restricted the direction that restores deformation after one-level compression spring 6 receives the pressure simultaneously.
A secondary compression spring 7 mounted between the radial positioning element 4 and the base plate 1. The secondary compression spring 7 is compressed and deformed when the radial bottom plate 1 and the annular support plate 52 slide relatively. More closely, because the first annular groove 12 is seted up on the surface of bottom plate 1, and a part of second grade compression spring 7 sets up in this first annular groove 12 to improved second grade compression spring 7 installation stability, prevented that it from producing radial displacement, the groove depth direction of first annular groove 12 has also restricted the direction that restores the deformation after second grade compression spring 7 receives the pressure simultaneously. Further, the elasticity of the second-stage compression spring 7 is 3-5 times of the elasticity of the first-stage compression spring 6, so that in the process of restoring the deformation, the second-stage compression spring 7 can exert larger acting force on the axial positioning piece 5 and the like.
When the second-stage buffering assembly tool in the embodiment is used, the rolling bearing 2 'is placed on the bearing support plate 32, and the bearing positioning column 33 penetrates through the rolling bearing 2'. The elastic clamping ring 3' is clamped into the radial positioning element 4 and abuts against the free end face of the clamping ring positioning part 51, as shown in fig. 3. The end cap positioning portion 41 is snapped into the positioning cavity 12 'of the end cap 1'. The end cover 1 and the radial positioning piece 4 are pushed to move along the axial center direction of the axial positioning column 3 towards the direction of the bottom plate 1. In the pressing process, under the reaction force of the first-stage compression spring 6 and the second-stage compression spring 7 and the action of the radial positioning piece 4 and the axial positioning piece 5, the elastic tight ring 3 'is firstly pressed into the installation cavity 11', as shown in the attached drawing 4. The rolling bearing 2 'is pressed into the elastic clamping ring 3' as shown in fig. 5. After the installation is finished, the working pressure is removed, the first-stage compression spring 6 and the second-stage compression spring 7 recover the influence, and a finished product is obtained after the push-out, as shown in figure 6.
The second grade buffering assembly fixture in this embodiment unites two into one two stations, can reduce anchor clamps and process input cost, promotes technological efficiency, reduce cost.
