As shown in Figures 3 and 4, Fig. 4 is the embodiment schematic diagram that swing arm guide unit lifts, swing arm guide unit 500 rotates for rotating shaft with the axle center C being parallel to axial P, C better also position in axle center is in the first plane 11, and swing arm guide unit 500 can lift relative to the first plane 11 or put down when rotated.In this embodiment, as shown in Figure 2, swing arm guide unit 500 comprises support arm 510; Support arm 510 can be arranged separately or in pairs.In the present embodiment, support arm 510 is arranged at the outside at first 100 two ends on axial P in pairs, and axle center C is arranged at the tail end of support arm 510.As shown in Figure 3, axle center C is positioned at the below of first 100.In addition, C position, axle center is in first 100 outside in contrast to the first clamping part 300, that is primary importance 111 is relative to the outside of the first clamping part 300; In other words, in the first plane 11, swing arm guide unit 500 and the first clamping part 300 points are in the both sides of primary importance 111.Due in the process lifted at support arm 510, angle between the part that tested soft board 10 is lifted and support arm 510 can constantly change, under above-mentioned design, between the part that support arm 510 and tested soft board 10 are lifted, the change of angle can be less, to reduce the parameter in process of the test.In addition, axle center C is better is positioned in the first plane 11; In other words, when swing arm guide unit 500 is set level, it to be positioned in the first plane 11, is beneficial to before carrying out survey formula, load tested soft board 10.
Swing type guide unit 500 is provided with aforementioned second clamping part 700, and the second clamping part 700 can move along the support arm 510 of swing arm guide unit 500 towards or away from first 100.As shown in Figures 2 and 3, the second clamping part 700 for being arranged at the paired clamping plate between two support arms 510, for the tested soft board 10 of clamping relative to the other end of the first clamping part 700; But in different embodiments, the second clamping part 700 also can be made up of different clamp structures such as the fixture of other patterns, clamping bar or suckers.Swing type guide unit 500 is provided with the guidance devices such as slide rail and installs, in order to move relative to swing type guide unit 500 for the second clamping part 700.As shown in Figure 3, the inner side of support arm 510 is provided with slide rail 530, and the end of the second clamping part 700 can be provided with slide block or pulley slides to coordinate with slide rail 530, and the second clamping part 700 can be moved towards or away from first 100.In addition, as shown in Figure 2, swing type guide unit 500 can be provided with the device such as step motor 501 and screw rod group 503, control the movement of the second clamping part 700 relative to swing type guide unit 500 to form driver module.But in different embodiments, driver module also can be made up of belt, conveying belt or other devices.
As shown in Figure 4, swing arm guide unit 500 tilts to lift relative to the first plane 11.When swing arm guide unit 500 lifts, namely tested soft board 10 can produce bending corresponding to cylinder surface 110.Cylinder surface 110 has the second place 112 at the other end relative to primary importance 111, wherein the second place 112 is preferably the straight line being parallel to axial P, tested soft board 10 terminates to contact with cylinder surface 110 from the second place 112, therefore, when swing arm guide unit 500 lifts angle difference, the second place 112 also may change thereupon.Second clamping part 700 jointly defines the second plane 12 with the second place 112; Specifically, second clamping part 700 clamps the position of tested soft board 10 and the second place 112 all in the second plane 12, when tested soft board 10 is lifted, namely the one side that the part that tested soft board 10 is lifted contacts with the second place 112 drops in the second plane 12, and the second plane 12 and the first plane 11 accompany an angle.Second plane 12 is a virtual planimetric position, and is goodly tangential on the second place 112 with first 100.Tested soft board 10 is when tested, and it is superimposed with the second plane 12 at least partly, and may move along the second plane 12.
Lifting in process at swing arm guide unit 500, the second plane 12 also tilts to lift relative to the first plane 11.Meanwhile, the second clamping part 700 moves along swing arm guide unit 500 towards first 100, to lower the tension force caused on tested soft board 10 because of swing arm guide unit 500 Angulation changes.Because the tolerance level that bent mainly for tested soft board 10 in the present embodiment and other mechanical properties are measured, if the impact of tension force is excessive in process of the test, the changed factor of test will be made too much, and the deciphering of impact to test findings; Therefore the impact that minimizing tension force brings will contribute to the accuracy increasing test.In addition, when the angle that swing arm guide unit 500 lifts relative to the first plane 11 is larger, because the speed and amplitude that now cause pulling force within the unit interval on tested soft board 10 increase, second clamping part 700 also can be very fast towards the speed of first 100 movement, effectively to dissolve tension force unnecessary on tested soft board 10.
As shown in Figures 2 and 4, swing arm guide unit 500 can control its rotation being rotating shaft with axle center C by another step motor 505, to lift relative to the first plane 11 or to put down.Step motor 505 is better can be associated with formula or control module 400 with the motor 501 of aforementioned driving second clamping part 700, to reach the aforementioned function lifting degree to control the second clamping part 700 movement with swing arm guide unit 500.In addition, separately can set up tension monitoring unit 410 and to arrange in pairs or groups control module 400, and be connected with the second clamping part 700, to monitor the pulling force that the second clamping part 700 is subject at any time, and monitoring result is sent to control module 400.In the preferred embodiment, make the second clamping part 700 upper pulling force be less than e to the error that strain of flexure causes measured, then the pulling force f that better control second clamping part 700 provides need meet following equation:
F< (Eh
2w)/(2eR) (formula 1)
Wherein: E is the young's modulus of tested soft board 10, h is the thickness of tested soft board 10, and w is the width of tested soft board 10, and R is the radius of first 100.
Namely control module 400 judges the speed of mobile second clamping part 700 according to monitoring result, and controls motor 501 and carry out.In different embodiments, tension monitoring unit 410 also can arrange and be connected to the first clamping part 300, to monitor the pulling force that the first clamping part 300 is subject to, and adjusts the position of the first clamping part 300 relative to first 100 and movement according to this.
Another as shown in Figure 5, in another embodiment, when swing arm guide unit 500 lifts relative to the first plane 111, the second clamping part 700 can parallel shafts be rotating shaft to the direction of P, and rotates relative to swing arm guide unit 500.Owing to lifting in process at swing arm guide unit 500, angle folded between swing arm guide unit 500 and tested soft board 10 also can change, therefore therefore angle change can be reduced by this design and produce the unnecessary bending on tested soft board 10, and more increase the accuracy of test result.
Figure 6 shows that the specific embodiment of soft board flexure proving installation.As shown in Figure 6, first 100, with the table top of support frame higher than board 90, makes first plane 11 at tested soft board 10 place can on table top.The position of first 100 axle portions erection can adjust up and down, has first 100 use of different-diameter with collocation under different testing requirement.Swing arm guide unit 500 has horizontal frame 550, and its two ends are connected to the top of two support arms 510, to form the structure of gate-shaped.Design thus, swing arm guide unit 500 can be made to have preferably rigidity, and only the support arm 510 that motor can drive both sides need be set in side.In addition, the first clamping part 300, second clamping part 700 and swing arm guide unit 500 all drive in the mode of motor driving belt; So as aforementioned, in different embodiments, also the mode of motor collocation screw rod the transmission combination of motor and belt can be replaced.
Fig. 7 A and Fig. 7 B is respectively schematic diagram and the process flow diagram of the first soft board flexure method of testing.As shown in figs. 7 a and 7b, first tested soft board 10 to be arranged between the first clamping part 300 and the second clamping part 700 and to contact the cylinder surface (step 7100) of first, that is, tested soft board 10 is arranged in the first plane 11, and with a surface contact primary importance 111.Now tested soft board 10 is better still maintains smooth state.Object according to test is different, goodly on tested soft board 10 is pasted with strainometer (strain gauge), carries out subsequent analysis to obtain required strain numerical value after a test.Then the two ends (step 7300) of tested soft board 10 are clamped respectively with the first clamping part 300 and the second clamping part 700.In the preferred embodiment, the first clamping part 300 and the second clamping part 700 can be connected to tension monitoring unit 410, to monitor the pulling force suffered by the first clamping part 300 and the second clamping part 700.In the preferred embodiment, for balancing the tension force on tested soft board 10, the value of thrust that better control second clamping part 700 provides is in the scope of previously described formula 1.
Then, in step 7500, mobile second clamping part 700, pastes cylinder surface 110 and bends, until the first flexure test position of tested soft board 10 to make tested soft board 10.In the preferred embodiment, namely tilt to lift with relative first plane 11 for rotating shaft rotary swinging arm formula guide unit 500 with axle center C, make tested soft board 10 paste cylinder surface 110 from primary importance 111 and bend.When swing arm guide unit 500 rotates, the second clamping part 700 is better to be moved along swing arm guide unit 500.In this embodiment, the first clamping part 300 maintains static, and swing arm guide unit 500 continues to rotate to change the angle between the first plane 11 and the second plane 12, until tested soft board 10 produces required amount of bow.Certainly, before lifting swing arm guide unit 500 and bending tested soft board 10, the position of the first clamping part 300 and the second clamping part 700 also first can be adjusted, to make the predeterminated position of bending generation on tested soft board 10.As shown in Figure 7 A, the free end of swing arm guide unit 500 may streak the top of first 100 and be positioned at first 100 opposition side diametrically with axle center C.Finally, detect and obtain the characteristic (step 7700) to be measured of tested soft board 10, such as beaming limit, ess-strain reaction, tolerance level or damage test.This test mode tests merely tested soft board 10 in the beaming limit of fixed position, or ess-strain reaction when reaching certain amount of bow.In addition, also can loosen and repeat the bending mode of step 7500 again to carry out tolerance level or damage test, now then not necessarily need to carry out step 7700 to obtain the data on tested soft board 10, and can number of bends arrange in pairs or groups tested soft board 10 destruction observation and obtain test result.
As shown in Figure 7 A, when swing arm guide unit 500 be relative first plane 11 lift time, the second clamping part 700 moves towards first 100 simultaneously; And when swing arm guide unit 500 rotate put down towards the first plane 11 time, the second clamping part 700 court moves away from the direction of first 100.Owing to having identical curvature for cylinder surface 110 during cylinder relative to axial P when first 100, therefore tested panel 10 and cylinder surface 110 contacts and the part that bends also all has identical curvature.Fig. 7 C is with the better motion path of conceptual illustration second clamping part 700 of coordinate function.As seen in figure 7 c, when being initial point with primary importance 111, the coordinate function of the second clamping part 700 is (Sx, Sy):
Sx=Rsinθ+(L–Rθ)cosθ
Sy=R(1–cosθ)+(L–Rθ)sinθ
Wherein: 0≤θ≤L/R, θ is the attached angle of bag, is namely pasted the central angle on bending cylinder surface 110 by tested soft board 10; R is the radius of first; L is that tested soft board 10 is from the length of primary importance 111 to the second clamping part 700 when shakeouing.
Fig. 8 A and Fig. 8 B is respectively schematic diagram and the process flow diagram of the second soft board flexure method of testing.As shown in Fig. 8 A and Fig. 8 B, step 8100 is similar to step 7500 with the step 7100 in the first method of testing in principle to step 8500.Only therefore, the object that a method of testing is main is to understand same tested soft board 10 in variant position by reaction during same flexibility, and tested soft board 10 repeatedly by bending time reaction, therefore in step 8500 swing arm guide unit 500 lift value can with step 7500 in different, and maintain this angle and do not put down when arriving preset value, the angle between the first plane 11 and the second plane 12 is fixed.Generally speaking, in step 8500 swing arm guide unit 500 lift that the better meeting of value is less than step 7500 lift value.
Then in step 8700, mobile first clamping part 300 and the second clamping part 700 simultaneously, make the first clamping part 300 towards first 100 direction close and the second clamping part 700 away from first.Specifically, this step is along the first plane 11 and move the first clamping part 300 towards first 100 direction, and simultaneously towards moving the second clamping part 700 away from first 100 direction along the second plane 12, making tested soft board 10 paste cylinder surface 110 and move and change deflected position.Therefore, the part tested soft board 10 being subject to first 100 compressing flex can change along with the movement of tested soft board 10, to carry out crooked test to diverse location.In the process of tested soft board 10 movement, first 100 goodly can be rolled, with the friction reduced and between tested soft board 10 thereupon; But in different embodiments, first 100 also can be set as not rolling, with the variability in minimizing system.In the preferred embodiment, it is identical or close that the translational speed of the first clamping part 300 to be controlled with the second clamping part 700 translational speed component in the tangential direction of cylinder surface 110 by the second clamping part 700, to reduce the value producing unnecessary tension force on tested soft board 10.Aforementioned cylinder surface 110 is better parallel with the second plane 12 by the tangential direction of the second clamping part 700.In addition, the translational speed of the first clamping part 300 or the second clamping part 700 also can be adjusted according to the monitoring result of aforementioned tension monitoring unit 410.
Then, in step 8900, mobile first clamping part 300 and the second clamping part 700 simultaneously, second clamping part 700 is close towards first 100 direction away from first to make the first clamping part 300.Specifically, this step along the first plane 11 and towards moving the first clamping part 300 away from first 100 direction, and moves the second clamping part 700 towards first direction along swing arm guide unit 500 simultaneously, makes tested soft board 10 paste cylinder surface 110 and moves.This moving direction is contrary with the moving direction in step 8700, better for testing tested soft board 10 at the tolerance level be repeatedly subject to when bending or carry out failure test, when strainometer also can be coordinated to obtain tested or tested after ess-strain reaction.Depending on the difference of test condition, step 8700 and step 8900 also can be implemented repeatedly.Finally, detect and obtain the characteristic (step 8950) to be measured of tested soft board 10, such as beaming limit, ess-strain reaction, tolerance level or damage test.This test mode tests merely tested soft board 10 in the beaming limit of fixed position, or ess-strain reaction when reaching certain amount of bow.In addition, also can loosen and repeat the bending mode of step 7500 again to carry out tolerance level or damage test, now then not necessarily need to carry out step 7700 to obtain the data on tested soft board 10, and can number of bends arrange in pairs or groups tested soft board 10 destruction observation and obtain test result.
