Abstract
The utility model relates to a rotary shaft pulling-out tool. A screw rod is coaxially arranged inside an outer sleeve; a screw which is in threaded connection is arranged on the outer circumference of the lower end of the screw rod; a long-strip hole in an axial direction is arranged on the outer circumference of the outer sleeve, and the screw is located in the long-strip hole; the screw rod is matched with a rotary handle in a threaded manner and a fixed handle is arranged on the outer circumference of the outer sleeve; and a threaded hole is arranged in the lower end face of the screw rod. The rotary shaft pulling-out tool not only has a simple structure, but also is suitable for penetrating into a narrow space to be directly aligned to a rotary shaft; and a screw rod structure of the tool is adopted so that the rotary shaft is rapidly mounted and dismounted and the working efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of rotating shaft puller, belongs to a kind of aid.
Background technology
In the aircraft manufacturing assembling process, in the tangible narrow space of some Assembly part, and be lower than working face, and for the rotating shaft of some assembling usefulness, its installation and removal are more difficult, inapplicable outer assistant engineer's tool, and its inefficiency produces potential safety hazard sometimes.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of rotating shaft puller, and this rotating shaft puller is not only simple in structure, and is applicable to go deep into small space, directly aim at rotating shaft, utilize its screw structure that carries, rotating shaft is loaded and unloaded fast, greatly improved operating efficiency.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of rotating shaft puller, and the coaxial leading screw that is provided with in overcoat, excircle is provided with the screw that is threaded in the lower end of leading screw, be provided with the strip hole of axial direction at the excircle of overcoat, screw is positioned at strip hole; Threaded engagement turning handle on leading screw is provided with fixed handle at the excircle of overcoat; Lower surface at leading screw is provided with screwed hole.
This rotating shaft puller adopts the form that is threaded of overcoat and leading screw, can make leading screw rise to reach the purpose of dismounting rotating shaft by the rotation turning handle, by spacing in strip hole of screw, guarantees that leading screw does not rotate simultaneously.
Description of drawings
Fig. 1 is the front view of rotating shaft puller.
Fig. 2 is the A-A cutaway view of Fig. 1.
Stereogram when Fig. 3 is the work of rotating shaft puller.
The specific embodiment
As depicted in figs. 1 and 2, a kind of rotating shaft puller at the overcoat 1 interior coaxial leading screw 2 that is provided with, is provided with the screw 3 that is threaded at the lower end of leading screw 2 excircle, is provided with the strip hole 4 of axial direction at the excircle of overcoat 1, and screw 3 is positioned at strip hole 4; Threaded engagement turning handle 6 on leading screw 2 is provided with fixed handle 7 at the excircle of overcoat 1; Be provided with screwed hole 5 in the lower surface of leading screw 2.
As shown in Figure 3, rotating shaft puller when work, with screwed hole 5 fixing with rotating shaft on, then screw 3 is passed strip hole 4 and is fixed on the leading screw 2, when rotation turning handle 6, leading screw 2 rises, and rotating shaft is extracted.
