Abstract
The utility model relates to a sleeve, including the sleeve body, steel ball and screw, the sleeve body is the cavity form, the steel ball is arranged in the internal side of sleeve middle part, the screw is arranged in sleeve is internal, just the screw is in the upper end of steel ball, the upper portion of the sleeve body is the outer hexagonal body, the inboard of sleeve body lower part is provided with the internal thread, the internal thread matches with the external screw thread structure of bolt. Compared with the prior art, the utility model discloses structural design is simple, the manufacturing of being convenient for, low cost for pneumatic wrench, torque wrench screw up stud.
Description
Technical field
The utility model relates to machine tool technical field, particularly a kind of sleeve tightening stud for pneumatic impact spanner, torque wrench.
Background technology
All stud is used in the many places of machinery industry.Stud is screwed in screwed hole with hand by the way of current bolt hook bolt exactly, then on the other end screw thread of stud, two nuts are twisted, twist one of them nut after two nuts are standby tight again and reinforcing is carried out to stud, take off from stud after two standby jack panels being unclamped after adding power.Effort, inefficiency when filling stud like this; Can not determine the loading moment be applied on stud simultaneously, there is potential safety hazard (the inadequate bolt hook bolt of loading moment may get loose, and loading moment is excessive, and screw thread may be had tooth pulled out).Along with the development of society, the requirement of the efficiency that people assemble stud and reliability is more and more higher, therefore researches and develops and is a kind ofly applicable to pneumatic impact spanner, the sleeve that stud tightened by torque wrench is the direction that we study.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structural design, is convenient to processing and manufacturing, with low cost, tightens the sleeve of stud for pneumatic impact spanner, torque wrench.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of sleeve, comprise sleeve body, steel ball and screw, described sleeve body is hollow form, described steel ball is placed in described sleeve body middle inside, described screw is placed in described sleeve body, and described screw is in the upper end of described steel ball, and the top of described sleeve body is outer hexahedron, the inner side of described sleeve body bottom is provided with internal thread, and described internal thread mates with the external thread structure of bolt.
Further, described screw is fluting flush end holding screw.
Further, described sleeve body middle inside is provided with bayonet socket, and described bayonet socket can block described steel ball.
The beneficial effects of the utility model are: tighten stud sleeve for pneumatic impact spanner, torque wrench, 1, structural design is simple, is convenient to processing and manufacturing, with low cost; 2, use this sleeve to tighten stud, that can improve stud greatly tightens efficiency; 3, this sleeve is used with torque wrench to stud loading moment, stud in use safety and reliability can be made.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sleeve of the utility model;
Fig. 2 is the top view of Fig. 1.
In accompanying drawing, the list of parts representated by each label is as follows:
1, sleeve body, 2, steel ball, 3, screw, 4, bolt, 5, bayonet socket.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As depicted in figs. 1 and 2, a kind of sleeve, comprise sleeve body 1, steel ball 2 and screw 3, described sleeve body 1 is in hollow form, described steel ball 2 is placed in described sleeve body 1 middle inside, described screw 3 is placed in described sleeve body 1, and described screw 3 is in the upper end of described steel ball 2, the top of described sleeve body 1 is outer hexahedron, be convenient to be connected with various pneumatic impact spanner, torque wrench by this device, the inner side of described sleeve body 1 bottom is provided with internal thread, and described internal thread mates with the external thread structure of bolt 4.
Preferably, described screw 3 is fluting flush end holding screw.
Preferably, described sleeve body 1 middle inside is provided with bayonet socket 5, and described bayonet socket 5 can block described steel ball 2.
Implement this device, during assembling stud, one end of stud is screwed into sleeve body 1 bottom, is connected with sleeve body 1 lower thread, have the pneumatic impact spanner of standard cartridges to be screwed in workpiece by stud rapidly with cover; Due to this device be screwed to stud time, only have any of steel ball and the top contact of stud, therefore anti-when moving back, this device is less than the coupling mechanism force of bolt hook bolt and workpiece with the frictional force of stud, this device can be exited stud rapidly with pneumatic impact spanner, use torque wrench to during bolt hook bolt loading moment be also same so.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
