Fig. 1 is the structural representation of the preferred embodiment of the utility model clamping device.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment; Embodiment, structure, characteristic and effect thereof to the clamping device that proposes according to the utility model specify as follows:
Aforementioned and other technology contents, characteristics and the effect of relevant the utility model can be known to appear in the following detailed description that cooperates with reference to graphic preferred embodiment.Explanation through embodiment; When can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the utility model; Yet the appended graphic usefulness that only provides reference and explanation is not to be used for the utility model is limited.
Please with reference to shown in Figure 1, the clamping device 1 that is used for the contact engaging and separating force test that the preferred embodiment of the utility model provides comprises fixed block 10, regulating part 11 and a pair of grip block 12.The top of fixed block 10 is passed in the bottom of regulating part 11, connects the top of grip block 12.
Fixed block 10 roughly is inverted " U " shape, comprise main part 102 and by main part 102 two ends to two side arm portions 104 that extend below.Two side arm portions 104 are obliquely installed each other, thereby between two side arm portions 104, form trapezoidal clip slot 106.Clip slot 106 at the breadth extreme that forms between two side arm portions 104 greater than its width that between the open end of two side arm portions 104, forms.A side of clip slot 106 also is provided with backboard 108 between two side arm portions 104, and promptly backboard 108 connects two side arm portions 104, and a side opening of clip slot 106 is sealed.Also be provided with the screw (not label) that is through to from main part 102 outsides in the clip slot 106 at the main part 102 of fixed block 10.
Regulating part 11 passes the screw in fixed block 10 main parts 102, and its lower end is connected with grip block 12.Regulating part 11 comprises screw rod 110, handle 111, location division 112 and afterbody 113.The screw thread of screw rod 110 can with the threaded engagement in the screw of fixed block 10 main parts 102.Location division 112 and afterbody 113 are arranged at the opposite end of screw rod 110 respectively.Location division 112 is tabular, and the axis direction that is approximately perpendicular to screw rod 110 extends, and is positioned at the clip slot 106 of fixed block 10.Afterbody 113 is cylindric, is used to connect the force transducer (figure does not show) of contact engaging and separating force proving installation.Handle 111 sockets also are fixed in the position of screw rod 110 near afterbody 113.Afterbody 113 is positioned at fixed block 10 outsides with handle 111.
A pair of grip block 12 is contained in the clip slot 106 of fixed block 10.A pair of grip block 12 same formation are inverted trapezoidal, and the width of promptly a pair of grip block 12 upper ends is greater than the width of a pair of grip block 12 lower ends.And the breadth extreme when this a pair of grip block 12 contacts; The breadth extreme that to be its upper end form between two side arm portions 104 less than clip slot 106 near the width of an end of fixed block 10 main parts 102, and the width that between the open end of two side arm portions 104, forms greater than clip slot 106.A pair of grip block 12 preferably is symmetrical set, i.e. the roughly rectangular trapezium structure of each grip block 12.A pair of grip block 12 relative to each other and the adjacent setting surface that can contact be clamping face 122, each clamping face 122 indentation is in order to the clamping exemplar.Offer locating slot 124 relative to each other on a pair of grip block 12 tops; Locating slot 124 is approximately perpendicular to clamping face 122 and is provided with; And the wall on the top of each grip block 12 formation locating slot 124 is shorter; Make a pair of locating slot 124 of a pair of grip block 12 form inverted " T " shape, thereby the location division 112 of regulating part 11 can be contained in a pair of locating slot 124.
The clamping device 1 of the utility model embodiment uses on the contact engaging and separating force testing machine, and preferably clamping device 1 top is fixed on the contact engaging and separating force testing machine support through force transducer, and exemplar is clamped in clamping device 1 bottom.When needing the clamping exemplar; At first rotate the handle 111 of regulating part 11; Its screw rod 110 relative fixed pieces 10 are moved up, promptly shift out gradually from fixed block 10, its location division a pair of grip block 12 of 112 drives upwards moves in the clip slot 106 of fixed block 10 simultaneously; Promptly the main part 102 towards fixed block 10 moves; Because the wider width that the clip slot 106 of fixed block 10 forms between the root of two side arm portions 104, a pair of grip block 12 can move along the location division 112 of regulating part 11 and separate certain distance relatively, can exemplar be positioned between a pair of jagged clamping face 122 like this.The handle 111 of backward rotation regulating part 11 then; Screw rod 110 relative fixed pieces 10 are moved down; Promptly move into the clip slot 106 of fixed block 10 gradually; Its location division a pair of grip block 12 of 112 drives moves down in the clip slot 106 of fixed block 10 simultaneously, and promptly the main part 102 away from fixed block 10 moves, like this because the width that the clip slot 106 of fixed block 10 forms between the open end of two side arm portions 104 is narrower; Move in opposite directions a pair of grip block 12 compelled location division 112 along regulating part 11 in the clip slot 106 of fixed block 10, thereby the distance between a pair of zigzag clamping face 122 is diminished to clamp exemplar.
The clamping device 1 of the utility model embodiment; Through a pair of grip block 12 being placed in the trapezoidal clip slot 106 of falling of fixed block 10; And drive grip blocks 12 through regulating part 11 and move up and down with the distance between a pair of zigzag clamping face 122 that changes a pair of grip block 12 along falling trapezoidal clip slot 106; And then the purpose of realization clamping exemplar, not only simple in structure, easy to operate, and the clamping area is big; Jagged clamping face 122 can effectively increase the friction force of clamping device 1 clamping exemplar, thereby has guaranteed the accuracy of exemplar clamping stability and contact engaging and separating force testing machine test data.
A side of clip slot 106 is provided with backboard 108 between two side arm portions 104 of fixed block 10; Be for when assembling clamping device 1; Can a pair of grip block 12 be inserted the space that two side arm portions 104 and backboard 108 surround jointly, convenient for assembly, but obviously in other embodiment of the clamping device 1 of the utility model; Also can omit backboard 108, and not influence the function of the clamping device 1 of the utility model.
The above only is the embodiment of the utility model, is not the utility model is done any pro forma restriction; Though the utility model discloses as above with embodiment; Yet be not in order to limiting the utility model, anyly be familiar with the professional and technical personnel, in not breaking away from the utility model technical scheme scope; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be not break away from the utility model technical scheme content, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
