Description
Technical field
The present invention relates to a kind of tester, more precisely, being a kind of screw rod torque force testing instrument.
Background technology
In electrified today with mechanization, screw rod can be described as being seen everywhere.Heavy-duty machinery is arrived greatly, it is small to arrive circuit
Plate, screw all play important effect everywhere.
Large scale can be compared for the screw rod used in some plant equipment or workpiece connection, when the size of screw rod occurs
Its torsion is turned when change will also change, thus for screw torsion need test, so as to
Later operation provides convenient.The device of test torsion is mainly torque spanner at present, but because its structure is more complicated often
Cost is higher, and production cost is also unattainable.
The content of the invention
The present invention mainly solves the technical problem present in prior art, a kind of simple in construction cheap so as to provide
Screw rod torque force testing instrument.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of screw rod torque force testing instrument, comprising a connector, a reference test bar, described test are fixedly connected with described connector
The end of bar is provided with a control head, is fixedly connected with leader on described control head, the side of described reference test bar is additionally provided with one
Pointer, described control head are provided with a dial, and described pointer can be according to the different distortion of described reference test bar described
Dial on indicate different scales.
As preferred embodiments of the present invention, described reference test bar is made up of paramagnetism niobium-base alloy.
Elastically-deformable reference test bar can occur under twisting force because the screw rod torque force testing instrument of the present invention is provided with,
And this elastic deformation can be reflected on dial with quantifying, whole device is simple in construction, and manufacturing cost is cheap.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the dimensional structure diagram of the screw rod torque force testing instrument of the present invention；
Fig. 2 is the dimensional structure diagram of the screw rod torque force testing instrument in Fig. 1, is now another visual angle.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
The invention provides a kind of cheap screw rod torque force testing instrument simple in construction.
As shown in Figure 1 and Figure 2, a kind of screw rod torque force testing instrument 1, it is fixed on described connector 21 comprising a connector 21
A reference test bar 22 is connected, the end of described reference test bar 22 is provided with a control first 23, one is fixedly connected with described control first 23
Handle 3, the side of described reference test bar 22 are additionally provided with a pointer 4, and described control first 23 is provided with a dial 5, described
Pointer 4 can indicate different scales according to the different distortion of described reference test bar 22 on described dial 5.
The screw rod torque force testing instrument, described reference test bar 22 are made up of paramagnetism niobium-base alloy.
The screw rod torque force testing instrument of the invention is provided with can occur elastically-deformable reference test bar, and energy under twisting force
This elastic deformation is reflected on dial with quantifying, whole device is simple in construction, and manufacturing cost is cheap.
Only illustrate the mentality of designing of the present invention in one embodiment above, in the case where system allows, the present invention can
To expand to while external more functional modules, so as to extend its function to greatest extent.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, it should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
