Abstract
The utility model discloses a device of fixed extensometer, its characterized in that: including base, vertical pole, down tube and extensometer support, the base is magnetic base, the lower extreme of vertical pole is fixed on the base, the fixed wing section fastener in upper end of vertical pole, the wing section fastener can reciprocate on vertical pole, the down tube activity is fixed on the wing section fastener, and the down tube can around the wing section fastener at vertical rotation in surface, the other end at above -mentioned down tube is fixed to the extensometer support. The utility model discloses a magnetic base fixes whole device on ferromagnetic type of object, the height of rethread adjustment wing section fastener and the regulation of rotating down tube realization extensometer height and angle to the realization is accurate fixed to the extensometer, improves the orientation survey precision, has simple structure, convenient assembling, and the accurate advantage in location can realize the fixed of different grade type extensometer.
Description
Technical field
This utility model relates to the device of a kind of fixing extensometer.
Background technology
Low cycle fatigue test many employings strain controlling, the height of extensometer and angle all need accurately to determine, the position controlled
Shifting amount is the most relevant with gauge length segment length, but is usually no more than 0.1mm, and how extensometer fits tightly with test specimen, the most accurately
The strain controlling that realizes be a vital link in low cycle fatigue test.In process of the test, extensometer form is different, its
The position put also can be different, therefore, design a can be used for freely regulating extensometer height, angle positioner for tired
Important realistic meaning is had for labor test.
Summary of the invention
The purpose of this utility model is to provide a kind of height freely regulating extensometer and angle so that extensometer with
Test specimen reaches to fit tightly, thus improves the extensometer fixing device of certainty of measurement.
This utility model solves technical problem and be the technical scheme is that the device of a kind of fixing extensometer, the end of including
Seat, vertical bar, brace and extensometer support, described base is magnetic bases, and the lower end of described vertical bar is fixed on base, institute
An aerofoil profile securing member is fixed in the upper end stating vertical bar, and described aerofoil profile securing member can move up and down on vertical bar, and described brace is lived
Move and be fixed on aerofoil profile securing member, and brace can be fixed at vertical rotation in surface, described extensometer support around aerofoil profile securing member
The other end at above-mentioned brace.
Described magnetic bases are electric magnet base, and base is provided with a rotary switch.
Described brace is first fixed on bearing, and described bearing is movably fixed on aerofoil profile securing member.
This utility model uses magnetic bases to be fixed on ferromagnetic type objects by whole device, then fastens by adjusting aerofoil profile
The height of part and rotation brace realize the regulation of extensometer height and angle, thus realize accurately fixing extensometer, improve
Test certainty of measurement, has simple in construction, easy to assembly, the advantage of registration, it is possible to achieve consolidating of dissimilar extensometer
Fixed.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model；
In figure, 1 rotary switch, 2 magnetic bases, 3 vertical bars, 4 adjusting screw rods, 5 nuts, 6 aerofoil profile securing members, 7 adjust
Joint screw rod and nut, 8 bearings, 9 braces, 10 screws, 11 extensometer supports.
Detailed description of the invention
Below according to the drawings and specific embodiments, the utility model is described in further detail:
From fig. 1, it can be seen that this utility model fixes the device of extensometer, prop up including base, vertical bar, brace and extensometer
Frame, described base is magnetic bases, and magnetic bases are electric magnet base, and base is provided with a rotary switch.Described vertical bar
Lower end is fixed on base, and an aerofoil profile securing member is fixed in the upper end of described vertical bar, and described aerofoil profile securing member can be on vertical bar
Moving up and down, described brace is first fixed on bearing, and described bearing is movably fixed on aerofoil profile securing member, and bearing and brace energy
It is fixed on the other end of above-mentioned brace at vertical rotation in surface, described extensometer support around aerofoil profile securing member.
Using method: be first placed on ferromagnetic object by this utility model, utilizes magneticaction that base is fixed on ferrum
On magnetic bodies.Then adjusting nut is loosened, move up and down aerofoil profile securing member, when aerofoil profile securing member is in suitable height
Time, tighten adjusting screw rod and nut fixes aerofoil profile securing member.Then upper and lower rotary support, after brace is adjusted to correct position, twists
Tight adjusting screw rod and nut location.If now, extensometer backing positions needs to adjust further, repeats said process.
The ultimate principle of the present invention and principal character and advantages of the present invention, the technology of the industry have more than been shown and described
Personnel are it should be appreciated that the present invention should not be limited by the examples, and the simply present invention's described in above-described embodiment and description is former
Reason, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes and improvements
Both falling within scope of the claimed invention, claimed scope is by appended claim and equivalent circle thereof
Fixed.
