Abstract
The utility model belongs to mechanical products, and relates to a lining puller which is used for airplane ground maintenance and automobile repair in a small space. The lining puller is composed of a sleeve, a screw rod, a nut, a bearing, a cylindrical pin and an eccentric tongue piece. The screw rod is arranged in the sleeve, one end of the screw rod is connected with the nut, the bearing is arranged between the sleeve and the nut, and a drawing function is achieved through threaded connection. The other end of the screw rod is hinged to the eccentric tongue piece through the cylindrical pin, the gravity center of the eccentric tongue piece is misaligned to a rotating shaft, and the eccentric tongue piece can rotate to be perpendicular to the screw rod under the action of self weight, so that a limiting function is achieved. The lining puller is suitable for disassembly of a lining in a narrow working space for an airplane or an automobile to be repaired, an original lining which can not be disassembled can be conveniently disassembled, work efficiency is improved, device maintenance period is shortened, labor intensity of air crews is reduced, and cost for replacing new elements is saved.
Description
Technical field
The utility model belongs to engineering goods, relates to a kind of little space lining puller for aircraft floor guarantee, motor vehicle repair.
Background technology
Usually for the dismounting of crossing clamping hub, usually the method that employing is directly knocked, electric drill destroys, lining is extracted, the lining that more renews then, the fragile lining of such method is wasted time and energy inefficiency, have a strong impact on the maintainability of equipment, and carry out the lining dismantlement work when not opening wide in the space and just become more difficult; The principle that also has utilization and lining endoporus to produce frictional force is made specific purpose tool lining is extracted from housing, and this class is not to scratch the lining endoporus easily, is exactly spacing unreliable easy inefficacy, and pulls out the cover effort, and effect is not fine.
Summary of the invention
The purpose of this utility model provides a kind of lining puller that can work in small space.
Technical solution of the present utility model is, formed by sleeve, nut, screw rod, bearing, eccentric tongue piece and straight pin, screw rod places sleeve, one section of screw rod is connected with nut, and the other end of screw rod is connected with eccentric tongue piece by straight pin, and bearing is between nut and sleeve, eccentric tongue piece can freely rotate around straight pin, and the center of gravity of eccentric tongue piece does not overlap with the straight pin axis, and during free state, eccentric tongue piece is vertical with screw rod under the gravity effect.
The beneficial effects of the utility model: the hinged structure of the utility model employing screw rod and eccentric tongue piece realizes limit function, rely on lining inner hole friction force transmission power to compare with existing special-purpose puller, spacing reliable, can not damage the lining internal diameter, simple in structure, easy to manufacture, and easy to use, low price is applicable to the dismounting of the lining that working space on the aircraft is narrow and small, originally the lining that can't dismantle can conveniently be pulled down, the dismounting of finishing a lining only needs 1～5 minute, has improved operating efficiency, has shortened the maintenance of equipment time, reduce flight crew's labour intensity, saved the cost of changing new parts.

The specific embodiment
Below in conjunction with Figure of description the utility model is described in further detail.
As Fig. 1 ~ shown in Figure 3, little space is made up of sleeve 1, nut 2, screw rod 3, bearing 4, eccentric tongue piece 5 and straight pin 6 with the lining puller, screw rod places sleeve, one end of screw rod is connected with nut, the other end of screw rod is connected with eccentric tongue piece by straight pin, and bearing is between nut and sleeve.Eccentric tongue piece can freely rotate around straight pin, and the center of gravity of eccentric tongue piece do not overlap with the straight pin axis, and during free state, eccentric tongue piece is vertical with screw rod under the gravity effect.
During use, in lining was installed in small space, lining did not knock the space, at first, stretched out screw rod, with eccentric tongue piece go to screw coaxial after, stretch in the bush hole; Secondly, treat that eccentric tongue piece passes completely through bush hole after, eccentric tongue piece goes under the deadweight effect and the screw rod vertical direction, rotation is regained screw rod to eccentric tongue piece and is closely contacted with lining; At last, sleeve is supported on lining mount pad place and lives with hand steered, fastening nut, and screw rod is regained, and lining is pulled.
For better implement the utility model, after eccentric tongue piece passes completely through lining, screw in order better screw rod to be regained, screw rod is provided with the cross-hole perpendicular to axis direction, is convenient to utilize auxiliary general utility tool to insert, and screws screw rod rapidly.
The utility model is spacing reliable, volume is little, simple in structure, easy to manufacture, easy to use, low price, be applicable to the lining dismounting that working spaces such as military aircraft, all kinds of civil aircraft, boats and ships, automobile, other plant equipment are narrow and small,, the lining that can't dismantle originally can be pulled down easily, the dismounting of finishing a lining only needs 1～5 minute, improved operating efficiency, shorten the maintenance of equipment time, reduced flight crew's labour intensity, saved the cost of changing new parts.
