Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
The embodiments of the present invention：A kind of auxiliary branch of waw-1000 types pressure testing machine test rod piece anti-bending strength
Frame includes 2 root posts 3 as shown in attached drawing 1-5, and anti-lifting crossbeam 4,3 top connection of each column are connected between column 3
There are 1 test specimen fixed frame 7, test specimen fixed frame 7 to be equipped with a groove 2, be placed with test specimen 5 in groove 2, biography is provided on test specimen 5
Power short beam 1, anti-4 bottom of lifting crossbeam are contacted with 9 surface of waw-1000 types pressure testing machine, and 1 top surface of power transmission short beam is tried with pressure
Test the contact of machine top panel 10.
When being tested, waw-1000 types pressure testing machine 9 generate pressure by pressure testing machine top panel 10 by
It is upper toward descending on power transmission short beam 1, and test specimen is transmitted the force to by the power transmission short beam rack 6 of 1 both ends lower edge of power transmission short beam
5, test specimen 5 positioned at the test specimen fixed frame 7 of its both ends lower edge by transferring force to column 3 and anti-lifting crossbeam 4, anti-lifting crossbeam
4 directly set up onto the workbench of waw-1000 types pressure testing machine 9, and transmit the force to waw-1000 type pressure testing machines
9。
In order to allow test specimen 5 to be smoothly erected on the test platform of waw-1000 types pressure testing machine 9, in test specimen 5
Both ends support test specimen 5 with a root post 3 respectively；Herein on basis, from Newton's third law：Two objects of interaction
Active force and reaction force between body is always equal in magnitude, and direction is on the contrary, act on same straight line.In the process of load
In, when pressure testing machine is to 5 one downward pressure of test specimen, test specimen 5 will necessarily give one upward counter-force of forcing press, if examination
The dead weight that power is more than testing machine is tested, then testing machine will be caused to be lifted, to influence the safety and test result of experiment；By the flat of power
Weigh volume, needs that a rod piece that can give pressure testing machine down force, pressure testing machine is looked for just to be unlikely to be lifted
And the safety and test result of experiment are had an impact.Then, one is arranged on the testing stand of waw-1000 types pressure testing machine 9
The both ends of the anti-lifting crossbeam 4 of root, anti-lifting crossbeam 4 are connect with the column at both ends 3 respectively, just can solve testing in this way
When the problem of preventing pressure testing machine to be lifted；In addition, pure in order to form one at 5 length direction middle(-)third of test specimen
The pressure of pressure testing machine is divided into uniform two parts by curved area using power transmission short beam 1, and be respectively acting on test specimen two are third
At branch；In order to ensure the stabilization of test specimen during the test, test specimen 5 is fixed using test specimen fixed frame 7.
1 group of power transmission short beam rack 6 is also placed on the test specimen 5,6 upper and lower of power transmission short beam rack is respectively provided with 1
Card slot 8,8 shape of lower bayonet slot are identical as 5 cross sectional shape of test specimen.Upper card slot 8 is used to be connected with power transmission short beam 1, and lower bayonet slot 8 is used
In being caught in test specimen 5, test specimen 5 is avoided to move.
The power transmission short beam rack 6 is obtained by the processing of test specimen fixed frame 7, by deviating from groove 2 in test specimen fixed frame 7
Top surface forms upper card slot 8 between welding 2 pieces of triangle connecting plates, 11,2 pieces of triangle connecting plates 11.Component can be thus provided
Versatility, processing it is more convenient, fast.
3 web of the column is set there are one hole corresponding with anti-4 cross section of lifting crossbeam, and anti-4 head end of lifting crossbeam is stretched
Enter into hole, and is welded to connect with column 3.To which column 3 and anti-lifting crossbeam 4 be linked together well.
It is to be detachably connected between the column 3 and test specimen fixed frame 7.The power transmission short beam 1 and power transmission short beam rack 6
Between to be detachably connected.Facilitate the replacement of parts.
The column 3 is I-steel.The materials of the holder of the utility model are not required to customize, for different test requirements documents,
Using common iron on the market can machine-shaping, have the advantages that low cost, it is convenient and efficient, repeatable utilize etc. it is multiple, from
And into simple pressure testing machine is repacked to the multifunctional equipment that can test rod piece anti-bending strength.Slightly by the power transmission short beam 1 of holder
Change can be used for testing the bend test of 3 stress.This holder can be used for testing the anti-bending strength of different cross section rod piece, circle
Shape, rectangle.When testing circular cross-section rod piece, the groove 2 of test specimen fixed frame 7 is set as arc-shaped, power transmission short beam is put
Set frame 6 lower bayonet slot 8 be also configured as it is arc-shaped.When testing rectangular section rod piece, the groove 2 of test specimen fixed frame 7 is arranged
For rectangle, the lower bayonet slot 8 of power transmission short beam rack 6 is also configured as rectangle.
The auxiliary stand of the utility model can be used for the bending resistance of waw-1000 types and its similar pressure testing machine test rod piece
Performance.
