Unless otherwise defined, all technology of using of this paper and scientific terminology are with to belong to the implication that those skilled in the art of the present invention understand usually identical.The term that uses in instructions of the present invention herein is not intended to be restriction the present invention just in order to describe the purpose of specific embodiment.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1, the impact test apparatus 100 of better embodiment of the present invention comprises test board 110, column 120, back up pad 130, impact sleeve 140, ram hammer (not shown) and solenoid valve 150.
In the present embodiment, test board 110 is the rectangular slab body structure.In other embodiments, test board 110 can be support frame structure, comprises a plurality of feets of platform and support platform.Certainly, test board 110 also can for circular, oval with and the plate body structure of shape.
Back up pad 130 is fixedly connected with column 120, and arranges with test board 110 intervals.Specifically in the present embodiment, an end of back up pad 130 is sheathed on column 120 regularly, and back up pad 130 be arranged in parallel with the table top of test board 110.Back up pad 130 offers through hole (figure is mark not).
See also Fig. 2, impact sleeve 140 is fixed on back up pad 130, and is concrete, passes the through hole of back up pad 130 for impact sleeve 140.Offer on the sidewall of impact sleeve 140 and tackle hole 141.Impact sleeve 140 comprises the main body 142 of flexible shape and the interface portion 143 of the truncated cone-shaped that little head end is fixedly connected with main body one end.The little head end of interface portion 143 arranges near test board 110, and ram hammer enters from the stub end of interface portion 143, passes from little head end.Specifically in the present embodiment, the axis of impact sleeve 140 is vertical with the table top of test board 110, and the diameter of the through hole of back up pad 130 equals the overall diameter of main body 142, and interface portion 143 is barred from outside through hole; Interception hole 141 is opened on the annular sidewall of main body 142.
Ram hammer can drop on test board in impact sleeve 140.During test, available hand is positioned over ram hammer in impact sleeve 140, unclamps ram hammer, and ram hammer drops on the test block (not shown) from impact sleeve 140, test block is carried out the shock resistance test.
See also Fig. 3 and Fig. 4, solenoid valve 150 is located at the outside of impact sleeve 140, and the spool 151 of solenoid valve 150 can stretch in the interception hole 141 of impact sleeve 140, and holds ram hammer.Specifically in the present embodiment, solenoid valve 150 is two, is fixed in back up pad 130 near a side of test board 110, and lays respectively at the relative both sides of impact sleeve 140.In order to hold easily ram hammer, the end that the spool 151 of solenoid valve 150 can stretch in the interception hole is provided with butt plate 153, but butt plate 153 move toward one another of two electromagnetism 150 and tackle ram hammer.The free end of butt plate 153 is formed with the breach of arc, and the shape of breach just can match with the shape of the head of ram hammer.
Carry out the auto impact test in order to control ram hammer, impact test apparatus 100 also comprises photoelectric sensor (not shown) and controller (not shown).Photoelectric sensor is positioned near the end opening place of impact sleeve 140 away from test board 110.Controller is electrically connected to photoelectric sensor and solenoid valve 150.Through impact sleeve 140 during away from an end opening of test board 110, the light that photoelectric sensor receives is stopped by ram hammer, thereby senses the number of times that ram hammer passes impact sleeve 140 whenever ram hammer.Wherein, photoelectric sensor is sensed ram hammer even number time through the end opening of impact sleeve 140 away from test board, and the spool 151 that controller is controlled solenoid valve 150 stretches in the interception hole 141 of impact sleeve 140 and holds ram hammer.For example, when ram hammer drops on test block in impact sleeve 140, this moment, the photosensors record ram hammer passed impact sleeve 140 for the first time; The ram hammer test specimen rebounds impact sleeve 140 when interior, the photosensors record ram hammer passes impact sleeve 140 for the second time, at this moment, controller is controlled in the interception hole 141 that solenoid valve 150 stretches into impact sleeve 140 and is held ram hammer, makes ram hammer be difficult to again fall and carries out secondary pulse.If need to carry out multiple shock test, controller is controlled solenoid valve 150 from the interception hole 141 interior retractions of impact sleeve 140, and ram hammer resets, and the repetition above-mentioned steps gets final product.
In addition, automatically reset in order to make ram hammer, impact test apparatus 100 also comprises fixed pulley, support, stay cord, motor.Support is fixedly connected with pillar 120, and is positioned at back up pad 130 tops.Fixed pulley is fixed on support, and with impact sleeve 140 over against.In the rotating shaft of stay cord one end system and motor, on another end system and ram hammer, stay cord is walked around fixed pulley, rises to desired height by the Electric Machine Control ram hammer.Motor is electrically connected to controller, and is controlled by the controller.
Above-mentioned impact test apparatus 100 is controlled the power on/off of solenoid valve 150 when impacting, the spool 151 of solenoid valve 150 is put in impact sleeve 140 from impact sleeve 140 sides, the ram hammer that after interception live to be impacted, bounce-back falls again, thus prevent after the ram hammer bounce-back again to the test specimen secondary pulse.
See also Fig. 5, the present invention also provides a kind of impact test method, adopts above-mentioned impact test apparatus 100, comprises the steps S201～S203.
Step S201, ram hammer impact test block after passing impact sleeve.Ram hammer is positioned over predetermined altitude, then does the movement of falling object, falls above impact sleeve, and passes impact sleeve, drops at last on test block, so that test block is carried out shock-testing.
Step S202, ram hammer rebound to impact sleeve, and the spool of solenoid valve stretches in the interception hole of impact sleeve ram hammer is tackled to impact sleeve.After ram hammer drops into impulse member, be subject to the bounce-back of test block, and in the impact sleeve that again rebounds, at this moment, the spool of solenoid valve stretches in the interception hole of impact sleeve and tackles with the hammer that liquidates, and prevents that ram hammer from again dropping on test block and test block is carried out secondary pulse.
Step S203, if repeatedly test, ram hammer and solenoid valve reset, repeating step S201～S202.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
