Description
Technical field
The utility model relates to assembly tool, especially a kind of screw thread installation and removal auxiliary tool.
Background technique
Threaded connection is the releasable connection for being joined together connected piece with screw element (or threaded portion of connected piece).
Common screw element has bolt, stud, screw and fastening nut etc., mostly standard component.When being connected by screw bolts, not by coupled
The limitation of material, simple structure, removably to be fixedly connected, and have many advantages, such as to connect can lean on, convenient disassembly, in work
It is widely applied in industry.
Spanner is a kind of tool of common installation and removal thread connection.Bolt, screw, spiral shell are twisted using lever principle
Female and other threaded fasteners.Spanner classification has back-up wrench, double offset ring spanner, combination wrenches, monkey wrench, box spanner etc..
Spanner is usually formed with the opening or sets of holes of grip bolt or nut in the one or both ends of shank.Threadingly direction of rotation when use
Apply external force in shank, bolt or nut can be twisted.So needing to have around bolt or nut enough when twisting bolt
Space.When twisting bolt or nut with back-up wrench, double offset ring spanner, combination wrenches, monkey wrench, radial space must be big
In using key length as the circular space of radius, just facilitate operation.
In real enterprise workshop, in order to meet production needs, machining equipment (lathe, cutter) is often defeated in roller-way
Machine both sides is sent, or even next to the material conveying that roller conveyor production needs, is able to satisfy various technique production needs.Respectively
The different equipment machine of kind is often very compact, so that partial threads attachment often allows hand with general utility tool side without enough spaces
Just entrance is carried out the work, even hand, spanner all cannot be introduced into.Cause be threadably secured part when tightening or dismantling,
It operates extremely difficult.It can not even carry out the work simultaneously.
When twisting bolt or nut using Open jaw type wrench, double offset ring spanner, combination wrenches, monkey wrench, radial space is small
When with using key length as the circular space of radius.The force side of spanner can not be rotated around bolt, and working efficiency is low, if empty
Between all too it is small, spanner can not be pulled at all.If lengthening set when bolt or nut axial space are also limited or when having obstacle
Cylinder can not also work.
The disclosure of background above technology contents is only used for the design and technical solution that auxiliary understands the utility model, not
The prior art for necessarily belonging to present patent application shows above content in this patent in no tangible proof
In the case that the applying date of application has disclosed, above-mentioned background technique should not be taken to the novelty of evaluation the application
And creativeness.
Utility model content
The utility model existing spanner installation and removal threaded connector there are aiming at the problem that, a kind of installation of screw thread is provided
With disassembly auxiliary tool.The tool forms a transmission mechanism with chain using two gears, and the torque of driving wheel is transmitted to
Driven wheel reaches the function of tightening or unclamp nut, screw.Particularly suitable limited with screw thread surrounding space, general utility wrench is not square
Just the occasion that operates or can not operate, achievees the effect that Labor-saving high-efficiency.
In order to achieve the goal above, the technical solution adopted in the utility model is as follows：
A kind of screw thread installation and removal auxiliary tool, including rack shell, driving wheel, driving chain and driven wheel；It is described
Driving wheel is mounted on driving shaft, and the driven wheel is mounted on driven shaft, and the driving wheel passes through driving chain and driven wheel
Connection, driving wheel, driven wheel and driving chain are in the same plane；The driving shaft is equipped with the component for torque input,
The component with sleeve cooperation is additionally provided on driven shaft, the driving wheel, driving chain and driven wheel are mounted on inside rack shell.
Further, the component inputted for torque and the component for torque input are respectively four angle heads or hexagonal
Head.
Further, the component for torque input is mounted on both ends of main drive shaft.
Further, bearing is additionally provided on the driving shaft and driven shaft.
Further, the bearing respectively designs 2 on driving shaft and driven shaft respectively.
Further, the number of teeth of the driving wheel is greater than driven tooth number.
Compared with prior art, it the advantages of the utility model and has the beneficial effect that：
1, the screw thread installation and removal auxiliary tool of the utility model forms one with chain using driving wheel and driven wheel
The torque of driving shaft is transmitted to driven wheel, reaches the function of tightening or unclamp nut, screw by transmission mechanism.It is particularly suitable with
Screw thread surrounding space is limited, and general utility wrench is inconvenient to the occasion that operates or can not operate, and reaching reduces labour and raising work
Make the effect of efficiency.
2, this auxiliary tool is equipped with four angle heads or turret head for torque input in both ends of main drive shaft, and both ends can make
With make bolt up or down when can facilitate operation, facilitate operation, the moment, to reduce labour strong downward for nutting, screw
Degree.
3, this auxiliary tool is by changing the gear ratio of driving wheel, driven wheel, and then changes ratio changing proportion of torque；
When active tooth number is greater than driven tooth number, labor-saving effect can be reached.
4, the tool of the utility model is adapted to complicated workplace；There is equipment on particularly suitable nut, bolt both sides,
Screw thread axes extending line has obstacle, the occasion that nigger spanner can not operate.
