Abstract
The utility model discloses an interference fit shaft dismounting device, comprising a sliding rod, a weight block, a weight block retaining device and a shaft fixing device, wherein a hole corresponding to the sliding rod is arranged in the weight block; the weight block is sheathed on the sliding rod through the hole and further slides relative to the sliding rod; the weight block retaining device is fixed on one end of the sliding rod; and the other end of the sliding shaft is provided with a shaft fixing device. With the adoption of the interference fit shaft dismounting device, through the arrangement of the weight block, the weight block retaining device and the shaft fixing device on the sliding rod, the sliding rod and an interference fit shaft are fixed together by the shaft fixing device; based on the inertia of the weight block, the interference fit shaft is dismounted; and therefore, the structure is simple, the use is convenient, and the time on dismounting the interference fit shaft can be shortened greatly.
Description
Technical field
The utility model relates to the provision for disengagement of a kind of interference fit axle.
Background technology
We run into the axle of interference fit through regular meeting in the daily production process, but the axle of interference fit removes very inconvenience, does not have special instrument to be used to dismantle the interference fit axle.
So, need the provision for disengagement of a kind of interference fit axle to address the above problem.
The utility model content
Goal of the invention: the purpose of the utility model is the deficiency that exists to prior art, and the provision for disengagement of a kind of interference fit axle is provided.
Technical scheme: for realizing the foregoing invention purpose, this practical interference fit axle provision for disengagement can be adopted following technical scheme:
The provision for disengagement of a kind of interference fit axle comprises sliding bar, pouring weight; Pouring weight retention device and shaft fixing device; Said pouring weight is provided with and the corresponding hole of said sliding bar, and said pouring weight is connected on the said sliding axle through said borehole jack, and said pouring weight can slide on said sliding bar; One end of said sliding axle is fixed said pouring weight retention device, and the other end of said sliding axle is provided with shaft fixing device.
Beneficial effect: compared with prior art; The provision for disengagement of the utility model interference fit axle is through being provided with pouring weight on sliding bar, pouring weight retention device and shaft fixing device utilize shaft fixing device that sliding bar and interference fit axle are secured together; Utilize the inertia of pouring weight that the interference fit axle is dismantled; Simple in structure, easy to use, can shorten take-down time of interference fit axle greatly.
