Abstract
The utility model discloses a tired anchor clamps of four -point bending of two spans, including pressure head, base and the supporting shoe that links to each other with the base, coexistence inter -plate on the base 1 has a constant head tank 9, and 2 joints of supporting shoe are in constant head tank 9 to through the supporting shoe and through coexistence board corresponding connecting hole the for roller and base associative, the upper and lower two sides of supporting shoe 2 is provided with the roller groove that has different spans, promptly: a roller groove 11 and a fourth roller groove 12 are propped up with a second roller groove 71 and third in first roller groove 7, the pressure head also has two, has the compression roller roller groove of different spans on each pressure head. The utility model discloses the supporting shoe only need be changed to anchor clamps can realize different spans and simple structure, firm, and easy dismounting practices thrift the cost, and is efficient.
Description
Technical field
The utility model relates to a kind of bending strength test device, specifically a kind of four-point bending fatigue testFixture.
Background technology
The tired fixture of traditional four-point bending is generally fluting or hole on overall base, then in the aboveLoad onto roller using as lower support position, so just make to test span and fix, if change a kind ofSpan, must change a whole set of fixture. So just increased the quantity of fixture, uneconomical.
Summary of the invention
In order to make up the deficiencies in the prior art, the purpose of this utility model is to provide a kind of 4 points of twin spans distanceRepeated bend test fixture, and make it to have simple in structure, facilitate easy-to-use advantage.
The Main Means that the utility model is realized object is:
The tired fixture of four-point bending of twin spans distance, comprises pressure head, base and the support being connected with basePiece. Between two risers on base 1, have locating slot 9, back-up block 2 is connected in locating slot 9, and passes throughBack-up block and being connected with roller and base by the corresponding connecting hole of two risers; The upper and lower surface of back-up block 2 is establishedBe equipped with the roller groove with different spans, that is: first roller roller groove 7 and second roller roller groove 71, the 3rdRoller roller groove 11 and the 4th roller roller groove 12; Pressure head also has two, has the pressure of different spans on each pressure headRoller roller groove.
Like this, the back-up block upper and lower side of the utility model fixture has the roller groove of corresponding different spans, is furnished with simultaneouslyThe pressure head of two span diverses; Back-up block and being connected of base are with crossing, back-up block to be stuck in base locating slot alsoConnect by roller; Base is all connected with testing machine by screw thread with pressure head; Base be overall structure withLocating slot.
The beneficial effects of the utility model are: can realize different spans by the upper-lower position of quick change back-up blockDemand, the method is simple, reliable in structure, and economic.
Brief description of the drawings
Fig. 1 is the mounting structure figure of the utility model embodiment.
Fig. 2 is the pressure head of another span of the utility model embodiment.
Fig. 3 is that the utility model is arranged on the side view after testing machine.
In figure: 1 base; 2 back-up blocks; 3 pressure head A; The pressure head of 4 another spans; 5 back-up block connecting holes;6 base connecting holes; 7 first roller roller grooves; 71 first roller roller grooves; 8 pressure roller roller grooves; 9 locating slots;10 risers; 11 the 3rd roller roller grooves; 12 the 4th roller roller grooves; 13 rollers; 100 samples. A, B, C,D: experiment roller.
Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present utility model is described in further detail.
As shown in figs. 1 and 3, the tired fixture of the four-point bending of twin spans distance, comprises base 1, back-up block 2,Pressure head, the lower part of fixture forms by 1,2, is connected with testing machine by the screw thread of base 1 lower end,On bracer 2, have back-up block connecting hole 5, on base 1, have base connecting hole 6, when experiment is installed, as figureShown in 1 direction of arrow by back-up block 2 is stuck in the locating slot 9 on base 1, and make back-up block connectHole 5 and base connecting hole 6 centerings, and by back-up block with by two risers corresponding roller 13 for connecting holeBe connected with base; The upper and lower surface of back-up block 2 is provided with the roller groove with different spans, that is: first rollerRoller groove 7 and second roller roller groove 71, the 3rd roller roller groove 11 and the 4th roller roller groove 12; Pressure head also hasTwo, on each pressure head, there is the pressure roller roller groove 8 of different spans.
When experiment, in each roller roller groove and pressure roller roller groove, place experiment roller A, B, C, D, from upper and lower twoFace makes that sample 100 is stressed tests.
Fixture is also furnished with two pressure heads of different spans, pressure head 3 and pressure head 4, the pressure roller roller groove on pressure head withThe roller groove of pressure head 3 has different spans.
Need to change a kind of span time, only need to take out roller, back-up block 2 is changed to a direction and install and change different pressuresHead. For having better stability, base has an above connecting hole that can Gong connect with back-up block.
Claims (2)
