The spring fatigue test machine provided by the utility model is reasonable in design and convenient in use. By the test machine, the compression test of the spring can be completed by the ingenious structure, and the use conditions of the spring can be accurately simulated, such that the test of the spring is accurate.
Description
Technical field
The utility model patent relates to a kind of be used to simulating the spring fatigue test machine of the actual testing fatigue of spring.
Background technology
One of core component of syringe is a high-intensity Compress Spring.The using method of spring is first to be compressed to certain-length, has possessed certain potential energy, then by control gear, spring is excited suddenly, the push rod of the pushing syringe action of injection that moved forward.The spring fatigue tester table is to utilize the cam Compress Spring now, and spring is moved reciprocatingly, and the shortcoming of prior art is:
1. cam rotarily drives the spring to-and-fro movement, can not go out to excite the compression of spring to excite situation by real simulation, easily the serviceable life of erroneous judgement spring, (excite the spring technical requirement: the spring access times that excite in injector were not less than 5000 times, adopt existing test machine test to excite spring life can reach more than 15000 times, the variation of size and dynamics still meets request for utilization.But will excite spring to install in injector while carrying out actual testing fatigue, and can only use left and right 1000 times, spring had just lost efficacy.）。By analyzing, can find out, the condition while exciting the actual service conditions of spring move than spring test machine is harsh a lot, has the request for utilization that the spring fatigue test machine can not meet us now.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome above-mentioned defect, the spring fatigue test machine that can accurately test Compress Spring.
Spring fatigue test machine provided by the utility model, is characterized in that, comprises swing connecting bar, and the swing connecting bar connecting sliding rail is cross-shaped, the end linking springs compressing mechanism of slide rail, and spring-compressed mechanism is placed in spring spool.
Swing connecting bar comprises fork and cam, the two ends of fork have the groove of strip, cam projection on cam is inserted the groove of fork one side, in the groove of fork opposite side, inserts the slide rail projection, and cam projection and slide rail projection all match with the width of groove on fork.
Slide rail is arranged in chute.
The end of slide rail is F shape end, and the afterbody of the upper horizontal edge of F shape end arranges the compressing bearing, the lower horizontal edge linking springs compressing mechanism of F shape end.
Spring spool is columnar structured, and its top has through hole.
Spring-compressed mechanism comprises piston ejector ram, ejector piston and resetting-mechanism, piston ejector ram, ejector piston is corresponding with the position of lower horizontal edge, resetting-mechanism comprises back-moving spring, block, one end of back-moving spring is fixed on spring spool, the other end is connected with block, block is the L shaped structure of traverse, connects back-moving spring under the long limit of block, and the minor face of shelves frame probes in the through hole of spring spool.Piston ejector ram, ejector piston is the T font
The beneficial effect that the utility model has is, reasonable in design, easy to use, completes the compression verification to spring by textural association cleverly, accurately simulates the environment for use of spring, more accurate to the test of spring.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is guide rail and spring-compressed mechanism structure schematic diagram;
Fig. 3 is that the utility model is guide rail and spring-compressed mechanism structure for amplifying schematic diagram;
In figure: 1, fork; 2, cam; 3, groove; 4, slide rail projection; 5, cam projection; 6, slide rail; 7, chute; 8, F shape end; 9, upper horizontal edge; 10, lower horizontal edge; 11, compressing bearing; 12, block; 13, back-moving spring; 14, piston ejector ram, ejector piston; 15, spring spool; 16, spring.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Swing connecting bar in spring fatigue test machine as shown in Figure 1 comprises fork 1 and cam 2, the two ends of fork 1 have the groove 3 of strip, cam projection 5 on cam 2 is inserted the groove 3 of fork 1 one sides, in the groove 3 of fork 1 opposite side, insert slide rail projection 4, cam projection 5 and slide rail projection 4 match with groove 3 width of fork 1, prevent power transmission process generation error, cam 2 rotations can accurately be transmitted on slide rail 6.Slide rail 6 is in the interior slip of chute 7.The end of slide rail 6 is F shape end 8, and the afterbody of the upper horizontal edge 9 of F shape end 8 arranges compressing bearing 11, the corresponding piston ejector ram, ejector piston 14 of the lower horizontal edge 10 of F shape end 8, and piston ejector ram, ejector piston 14 is placed in spring spool 15.Spring spool 15 upper ends connect back-moving spring 13, and the other end of back-moving spring 13 connects block 12, and block 12 is the L shaped structure of traverse, and its end probes in the through hole of spring spool 15, block 12 setting corresponding to piston ejector ram, ejector piston 14.
During use, at first spring 16 puts into spring spool 15, and piston ejector ram, ejector piston 14 inserts spring 16.Cam 2 rotates and then drives fork 1 and swings, and fork 1 drives 4 side-to-side movements of slide rail projection, makes slide rail 6 in the interior slip of chute 7.As shown in Figure 3, when slide rail 6 slides to the right, the upper horizontal edge 9 of F shape end 8 and lower horizontal edge 10 move right simultaneously, lower horizontal edge 10 heads on piston ejector ram, ejector piston 14 Compress Springs 16, the end of the compressing bearing 11 compressing blocks 12 of upper horizontal edge 9, simultaneously block 12 ends are moved downwards, block piston ejector ram, ejector piston 14, piston ejector ram, ejector piston 14 can't be rebounded.When fork 1 drives slide rail 6 slip left, the upper horizontal edge 9 of F shape end 8, lower horizontal edge 10 simultaneously left, are now oppressed bearing 11 and are slowly moved and oppress block 12 backward, and block 12 ends are slowly upwards lifted, no longer block piston ejector ram, ejector piston 14, make spring 16 enter excited state.Cam 2 not stalls are moving, make ceaselessly side-to-side movement of slide rail 6, reach test purpose.
