Fig. 5 is the part sectional front view, expresses an embodiment configuration according to the Material Testing Machine of second aspect present invention feature.
With the first aspect present invention feature similarity, in Material Testing Machine according to the embodiment of second aspect present invention feature, a pair of screw rod 2 is separately positioned in the box-shaped column 1 that a pair of horizontal section takes the shape of the letter U rotationally, and box-shaped column 1 vertically is separately positioned on two opposite sides.Crossbearer 3 is placed between the column 1, and the opposed end of crossbearer 3 cooperates with screw rod 2 respectively by nut 4.A pair of chuck 5 is connected with board 6 with crossbearer 3 respectively with 5, and test block 7 just can be held between chuck 5 and 5 like this.When screw rod rotated, it moved up and down crossbearer 3, thereby the test block 7 that chuck is holding is imposed tensile load etc., so that test out pulling strengrth of test block 7 etc.Label 8 indications are that the dynamometer of lotus value is cut out in a detection.Crossbearer 3 be configured as a rectangular entity, its vertically in the middle of the place be provided with a through hole (not shown).The upper end of chuck 5 is passed through hole and is connected with dynamometer 8, so that determine the load on the test block 7.Label 9 indications are a connecting link.
In the present embodiment according to the second aspect present invention feature shown in Figure 5, be provided with spatial portion 3K on a large scale respectively in 3 liang of opposite end portions of crossbearer with near screw rod 2 inboard places, tabular cover 30 is provided with along screw rod 2 directions and passes space 3K (not shown left side inner case) on a large scale, like this, tabular cover 30 just can move up and down with respect to column respectively.Above-mentioned ＂ is meant that near screw rod 2 inboard ＂ ＂ is respectively near screw rod 2 and at the ＂ of the inboard place of screw rod.The position in space preferably is in the open sides of channel section column 1 is sealed on a large scale.If the distance of space 3K screw rod 2 corresponding with it is too near on a large scale for each, then on a large scale between the end of space 3K and the nut 4 distance just reduce, consequently physical strength weakens, the problem like that causes rupturing occurs.So, consider above-mentioned situation, distance value should be set in the zone of reasonableness.Screw rod 2 is provided with to such an extent that can be enclosed in respectively in the box-shaped column 1 by tabular cover 30.This sealing is not the sealing of desirable impermeability, because gapped existence between tabular cover 30 and the column 1, but screw rod 2 still is enclosed in separately the column 1 basically respectively.
The present embodiment of second feature has a key character according to the present invention, is exactly that tabular cover 30 is provided with to such an extent that can move up and down.Specifically, each top and bottom of tabular cover 30 are all T-shaped, and elastic body 12A and 12B (for example, volute spring) then are placed between the T shape end face and frame of tabular cover 30.Volute spring is provided with to such an extent that can be compression spring, also can be extension spring.Along with the appearance that moves up and down of tabular cover 30, signal output is just arranged, according to this signal, machine just stops its operation.As shown in Figure 5, all use screw 15 and 16 fixing brake component 13 and 14 respectively on each tabular cover 30, they are positioned at the above and below of crossbearer 3.Gib screw 15 and 16 by formed slot 30S on the tabular cover 30 respectively with tabular cover 30 trailing flanks on nut body 17 and 18 screw threads sealed.Nut body should be done to such an extent that make respectively and carry out the sealed nut of screw thread when contacting tabular cover 30 with screw 15 and 16, and this contact is flexible.In addition, when screw 15 and 16 became flexible, brake component 13 and 14 can move along slot 30S, thereby makes it be fixed on desired position.
In above-mentioned configuration, when not only movement travel was greater than scheduled volume after crossbearer 3 is finished test, it can bump and lean against on the brake component 13 (14), and when crossbearer 3 further moved, tabular cover 30 also can be subjected to the elastic force effect of volute spring 12A and 12B.Above-mentioned motion is detected by the SK of testing agency.Fig. 7 at length expresses the SK of testing agency situation.As shown in Figure 7, a U-shaped framework 19 is fixed on the back of tabular cover 30, and it has a light emission part 20 and a light receiver 21.Shadow shield 22 is erected on the bearing 23, and is inserted among the U-shaped framework 19, and bearing 23 is arranged on the board 6.Under state shown in Figure 7, shadow shield plays interception, spreads out of from light receiver 21 so be provided with signal.When tabular cover 30 heads on the elastic force of volute spring 12A and 12B and when moving, then the shading state is eliminated, so the motion of tabular cover 30 just is detected.
In addition, when such as an external structure body when placing between the nut 4 of tabular cover 30 and crossbearer 3, crossbearer 3 just and tabular cover 30 just be combined into one, so tabular cover 30 will be driven by the operation of crossbearer.Under this situation, light receiver 21 will be exported a monitor signal.
Although space 3K shown in Figure 5 is provided in a side of the space on a large scale on the crossbearer 3, be not on crossbearer 3, to establish this space on a large scale, also slot can be set, as long as the space that slot had can allow tabular cover 30 pass through wherein respectively.Under situation shown in Figure 8, slot 3S is provided with along vertical crossbearer 30 extending longitudinallies, is prepared into the tabular cover 30 that can insert slot 3S like this and just can have passed through slot 3S.Distance between crossbearer 3 and the tabular cover 30 must keep constant, even crossbearer 3 moves forward and backward when testing like this, they can not contact with each other yet.Certainly, very the more important is, although be provided with tabular cover 30, crossbearer 3 still can move up and down.Tabular cover 30 not only can be used as barrier, prevents the intrusion of dust and foreign body, and guarantees safety, but also can prevent that hand or instrument accident from entering the sort of situation generation in the Wavelet piece.Like this, the problem of Wavelet piece generation distortion just has been readily solved in the prior art.Moreover crossbearer 3 can move up and down between board 6 and connecting link 9, so compared with prior art, its effective travel has enlarged.In the present embodiment that is provided with slot 3S, also have an advantage, Here it is, and crossbearer 3 can also make the entity rectangle, so just can have higher mechanical strength, desirable outward appearance or the like.
In this embodiment, tabular cover 30 is provided with to such an extent that can move up and down equally.That is to say that the upper end of each tabular cover 30 is by the lower surface of connecting link 9, its bottom is then by board 6.In this case, the clear size of opening on the board 6 should be done as far as possible near the size of tabular cover 30, to reduce spacing between the two.In addition, be provided with T shape plate 30T in each end of tabular cover 30.Volute spring 24 and 25 is separately positioned between T shape plate 30T and the connecting link 9 and between T shape plate 30T and the board 6.
So tabular cover 30 can move up and down under the elastic force effect.In addition, on connecting link 9 and board, also be respectively equipped with micro switch 26 and 27 facing to T shape plate 30T place.In above-mentioned configuration, when for example an external structure body jam was between crossbearer 3 and tabular cover 30, tabular cover 30 will move up and down with the motion of crossbearer.Then, microswitch 26 (27) starts at once, exports a signal, so the driving mechanism on the board just promptly stops, produces accidents such as fracture, damage to avoid machine.Even because operator carelessness, when putting into its hand or instrument between crossbearer 3 and the tabular cover 30, test also can be out of service safely immediately.
