Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1:
the first elastic support shaft assembly 1 is provided with a first threaded hole 11 which is coaxially communicated and is positioned on the left side and an inner conical surface hole 16 which is positioned on the right side, the inner conical surface 14 of the inner conical surface hole 16 is matched and installed with the outer conical surface 23 of the second elastic support shaft assembly 2, and the bottom surface 13 of the inner conical surface hole 16 is used for dismounting. The outer cylindrical surface 15 will be interference fitted with the through hole 61 of the torsion arm 6. The right end face 12 will abut against the middle step end face 21 of the second resilient support shaft assembly 2.
As shown in fig. 2:
the left part of the second elastic supporting shaft component 2 is an outer cone frustum, and the outer cone surface 23 of the outer cone frustum is matched with the inner cone surface 14 of the first elastic supporting shaft component 1. The juncture of the outer cone frustum and the right part of the second elastic supporting shaft component 2 is a middle step end face 21, and the middle step end face 21 is tightly attached to the right end face 12 of the first elastic supporting shaft component 1. The outer conical surface 23 is provided with an annular hydraulic oil groove 22, and a hydraulic oil connecting hole 25 connects the right end surface of the second elastic support shaft assembly 2 and the hydraulic oil groove 22. The second resilient support shaft assembly 2 has an axial second threaded bore 24 for use when disassembled, the second threaded bore 24 being of a larger diameter than the first threaded bore 11 of the first resilient support shaft assembly 1.
As shown in fig. 3:
when in use:
the outer cone of the second resilient support shaft assembly 2 is inserted into the inner cone hole 16 of the first resilient support shaft assembly 1, and the inner cone surface 14 of the inner cone hole 16 is fitted with the outer cone surface 23 of the outer cone of the second resilient support shaft assembly 2.
The connecting bolt 3 passes through the second threaded hole 24 with a larger diameter and then is screwed into the first threaded hole 11 with a smaller diameter, and the connecting bolt head 31 of the connecting bolt 3 presses the right end face 26 of the second elastic supporting shaft component 2.
And screwing the connecting bolt 3, propping against and attaching the right end face 12 of the first elastic supporting shaft component and the middle step end face 21 of the second elastic supporting shaft component 2, and assembling the second elastic supporting shaft component 2 and the first elastic supporting component 1 in place.
During the process of tightening the connecting bolt 3, the inner conical surface 14 and the outer conical surface 23 contact and are pressed against each other, after the inner conical surface 14 and the outer conical surface 23 are assembled in place, the inner conical surface 14 and the outer conical surface 23 are assembled together in an interference fit manner, and the elastic deformation causes the size of the portion, corresponding to the inner conical surface 14, of the outer cylindrical surface 15 of the first elastic supporting shaft assembly 1 to expand.
As shown in fig. 4:
after the assembled second elastic support shaft assembly 2 and first elastic support shaft assembly 1 are integrally frozen to be entirely contracted (or the torsion arm 6 is heated so that the through hole 61 is enlarged), the through hole 61 passing through the torsion arm 6 is assembled with the torsion arm 6 with the position of the inner tapered surface 14 corresponding to the through hole 61.
After the temperature returns to normal, the outer cylindrical surface 15 is fitted to the torsion arm 6 with interference with the through hole 61 of the torsion arm 6.
Therefore, the elastic support shaft tool is in an installation state.
As shown in fig. 5:
when the elastic support shaft tool is in a disassembly state:
when the elastic support shaft tool needs to be disassembled, the connecting bolt 3 is taken out, the disassembling bolt 4 is screwed into the second threaded hole 24 of the second elastic support shaft assembly 2, and the diameter of the second threaded hole 24 is larger than that of the first threaded hole 11, so that after the disassembling bolt 4 passes through the second threaded hole 24, the bottom surface of the disassembling bolt can be abutted against the bottom surface 13 of the inner cone hole 16, particularly against the bottom surface 13 part of the outer ring of the first threaded hole 11.
As the interference fit causes the second resilient support shaft assembly 2 to be unable to rotate relative to the first resilient support shaft assembly 1, continued tightening of the release bolt 4 gives the second resilient support shaft assembly 2 a rightward thrust, tending to move the second resilient support shaft assembly 2 out of the internal tapered bore 16.
Meanwhile, hydraulic oil is pumped into the hydraulic oil connecting hole 25, and the hydraulic oil is pumped into the hydraulic oil groove 22 to respectively apply pressure to the outer conical surface 23 and the inner conical surface 14, so that right thrust is applied to the second elastic supporting shaft assembly 2.
As shown in fig. 6:
the second elastic support shaft assembly 2 is removed from the first elastic support shaft assembly 1 by the hydraulic oil and the removal bolt 4. After removal, the outer cylindrical surface 15 of the first flexible support shaft assembly 1 is no longer in interference fit with the through-hole 61 of the torsion arm 6, and the first flexible support shaft assembly 1 can be easily removed from the torsion arm 6.
The utility model is formed by combining a first elastic supporting shaft component 1, a second elastic supporting shaft component 2 and a connecting bolt 3; the first elastic supporting shaft assembly 1 is provided with a first threaded hole 11, so that assembly is facilitated; the first elastic support shaft assembly 1 and the second elastic support shaft assembly 2 are respectively provided with a right end face 12 and a middle step end face 21 which are mutually contacted, and a part position connecting bolt 3 is controlled during assembly to ensure that the mounting is not loosened in place; the inner conical surface 14 and the outer conical surface 23 which are matched with each other are in interference fit after being installed in place, so that the outer cylindrical surface 15 is expanded, and the interference magnitude of the tool and the torque arm 6 during installation is ensured; the second elastic supporting shaft assembly 2 is provided with a hydraulic oil hole 25, a hydraulic oil groove 22 and a second threaded hole 24, so that the second elastic supporting shaft assembly is convenient to disassemble.
