Abstract
The invention provides a kind of large-scale fibre metal wall panel structure fatigue test machine clamp, technical points are that the surface of tensioning chuck two is designed as waveform decorative pattern lines, with the frictional force increased and between fatigue tester connection, and simple installation.With testpieces by three row's high intensity friction-type bolt connections, the shank of bolt of the connected mode does not receive shearing force to clamping plate so that experimental result is more accurate.Backing plate is prepared into splice type and two surfaces carry the shape of raised rectangular configuration, and when the testpieces for changing different-thickness carries out fatigue test, splice type backing plate is easily changed and adjusts, and simplifies operation.Backing plate realizes that such connected mode has not only acted as the effect of pre- anti-clamping plate warpage with the connected mode of clamping plate by the form of rectangular channel, and backing plate and clamping plate precise positioning, and backing plate can be made to be difficult to drop.
Description
Technical field
The present invention relates to a kind of large-scale fibre metal wall panel structure fatigue tester jig Design, belong to machining equipment
Manufacturing technology field.
Background technology
Under normal circumstances, the standard fixture of large-scale fatigue tester is specific to standard specimen carries out tension test and matches somebody with somebody
It is standby, for the ductility test part for needing to carry out tension and compression load test, prevent testpieces from occurring to bend usually using constraint guide plate
Qu Xianxiang.But proved by a series of experiments, in repeated tension and compression test, be likely to result in clamping plate using constraint guide plate and be adjacent to
Sample, and then cause that testpieces bears additional load during clamping force is applied, so that result of the test is inaccurate.Tradition
Fixture couple with fatigue test machine grip holder by screw thread, prolonged assembly and disassembly easily damaged screw makes its service life reduction, and spiral shell
Line connection requires there is preferable self-locking performance, so carrying out the selection of thread material and pitch and realizing complex and difficulty.
In addition, when large-scale fibre metal wallboard carries out tension test, backing plate is generally connected with clamp body by pin, different chis are being changed
, it is necessary to clamper for disassembling and pin change backing plate during the System for Large-scale Specimen of very little different-thickness, disassembly process is very cumbersome, test efficiency
Reduce.
The content of the invention
Regarding to the issue above, the present invention is proposed and a kind of carries out tension test suitable for large-scale fibre metal wall panel structure
Fixture, the jaw face being connected with testing machine is designed as waveform decorative pattern lines, and it is connected with fatigue test machine grip holder to increase
Between frictional force.Backing plate is prepared into splice type and two surfaces carry the shape of raised rectangular configuration, and splice type backing plate is easier to more
Change and adjust, simplify operation.Backing plate realizes that such connected mode is not only with the connected mode of clamping plate by the form of rectangular channel
The effect of pre- anti-clamping plate warpage is served, and backing plate and clamping plate precise positioning can be made.Clamping plate is high by three rows with testpieces
Intensity friction-type bolt connection, the bolt of this connected mode will not be subject to shearing force, so that result of the test is more accurate.
Basic technical scheme：
A kind of large-scale fibre metal wall panel structure fatigue test machine clamp, it is characterised in that described a kind of large-scale fibre metal
Wall panel structure fatigue test machine clamp is by pin（1）, pin for suppressing metal nut（2）, arm-tie（3）, tensioning chuck（4）, clamping plate
（5）, high-strength bolt（6）, high strength nut（7）, splice type positioning backing plate（8）, testpieces（9）Composition, fixture tensioning chuck
Step up to be connected by waveform decorative pattern with fatigue tester, for realizing that large-scale fibre metal wallboard carries out wanting for fatigue test
Ask.
It is of the invention further to improve, clamping plate（5）Backing plate is positioned with splice type（8）Between using rectangular channel connect coordinate, this
The connected mode of sample can both play a part of pre- anti-clamping plate warpage, and backing plate can again be accurately positioned, and be difficult to drop.
It is of the invention further to improve, clamping plate（5）With testpieces（9）Between by three row's high strength exploitations, bolt connects
Mode is connect for friction-type connection, the shank of bolt of this connected mode does not receive shearing force, makes experimental result more accurate.
It is of the invention further to improve, backing plate（8）Splice type is prepared into, when the fibre metal wallboard experiment for changing different-thickness
When part carries out fatigue test, splice type backing plate is easily changed and adjusts, and simplifies operation, improves test efficiency.
The beneficial effects of the invention are as follows：The surface of fixture tensioning chuck two of the invention is designed as waveform decorative pattern lines, both
The stress concentration phenomenon that threaded connection is produced can be eliminated, operation can be simplified again, be easy to operation.Clamping plate need not set positioning
Hole, splice type positioning backing plate can be connected with upper lower plate by rectangular channel, not only simplify operation but also energy precise positioning.Testpieces and folder
Plate uses three row's high strength exploitations, and bolt connecting mode is friction-type connection, and the bolt of this connected mode only plays positioning
Effect is without by shearing force, making experimental result more accurate.Splice type positioning backing plate can be according to the difference of testpieces thickness at any time
Change, it is simple to operate, improve test efficiency.
