Abstract
The utility model relates to the technical field of thread fasteners, in particular to a stud disassembling sleeve, comprising an outer convex tightening head and a disassembling body which are connected into a whole, wherein the disassembling body is internally provided with an inner bushing and is also internally provided with a rolling needle, a gasket and a retaining ring. In the stud disassembling sleeve, the structure is simple, the use is convenient, the rolling needle and the structure in the disassembling body can lock a stud disassembled, the torque is larger than the torque of 215N.m when in installation, the phenomenon of no loss of long studs and short studs in disassembly is ensured; and after hydraulic power is matched for the stud disassembling sleeve, the operation is simple and convenient, the safety and the reliability are achieved, the labor efficiency is greatly improved and the cost of repairing a car is reduced.
Description
Technical field
The utility model relates to a kind of pulling off sleeves, relates in particular to a kind of double-screw bolt pulling off sleeves.
Background technology
In the assembling of mechanical connection critical piece connected, bolt was used widely.When double-screw bolt connects in assembling, need earlier double-screw bolt to be screwed in the screwed hole of an end connection.Cooperate tighter occasion with screwed hole for double-screw bolt, these double-screw bolts can't directly be used tightening tool; Be screwed into the occasion that screwed hole moment has requirement for double-screw bolt, these double-screw bolts also can't directly be used and turn round the instrument assembling surely, cause double-screw bolt assembling, dismounting inconvenience, do not have extracting tool, can only slice off, and cause product rejection.
Summary of the invention
The technical problems to be solved in the utility model is: cooperate tighter occasion with screwed hole for double-screw bolt, these double-screw bolts can't directly be used tightening tool; Be screwed into the occasion that screwed hole moment has requirement for double-screw bolt, these double-screw bolts also can't directly be used and turn round the instrument assembling surely, cause double-screw bolt assembling, dismounting inconvenience, do not have extracting tool, can only slice off, and cause product rejection, and a kind of double-screw bolt pulling off sleeves is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises evagination tappet head and dismounting body, dismounting body and evagination tappet head are connected as a single entity, be provided with interior cover in the described dismounting body, also be provided with needle roller, pad and back-up ring in the dismounting body.
According to another embodiment of the present utility model, further comprise between described interior cover and the dismounting body being provided with single direction thrust ball bearing.
According to another embodiment of the present utility model, comprise that further described pad places needle roller one side, back-up ring places pad one side.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to use, needle roller and structure can be pinned in use and be disassembled double-screw bolt in the dismounting body, the moment of torsion 215N.m of moment of torsion when installing guarantees that the length double-screw bolt does not have the damage of tearing open phenomenon when disintegrating, after the adapted hydraulic power, simple to operation, safe and reliable, raise labour efficiency greatly, reduce the cost that repairs.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that Figure 1A-A is to structural representation;
Wherein: 1, single direction thrust ball bearing, 2, interior cover, 3, the dismounting body, 4, needle roller, 5, pad, 6, back-up ring, 7, the evagination tappet head.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, comprises evagination tappet head 7 and dismounting body 3 among the figure, and dismounting body 3 and evagination tappet head 7 are connected as a single entity, and cover 2 also is provided with needle roller 4, pad 5 and back-up ring 6 in being provided with in the described dismounting body 3 in the dismounting body 3.The curvilinear structures that interior cover 2, needle roller 4, pad 5 and back-up ring 6 form, can pin in use and be disassembled double-screw bolt, the moment of torsion 215N.m of moment of torsion when installing, guarantee that the length double-screw bolt does not have the damage of tearing open phenomenon when disintegrating, after the adapted hydraulic power, simple to operation, safe and reliable, raise labour efficiency greatly, reduce the cost that repairs.
Be provided with single direction thrust ball bearing 1 between cover 2 and the dismounting body 3 in described.Single direction thrust ball bearing is applicable to and bears on the lower parts of an axial load, rotating speed.Simple to operation, safe and reliable, raise labour efficiency greatly, reduce the cost that repairs.
