Embodiment
Contrast accompanying drawing below, through the description to preferred embodiment, specific embodiments of the invention is done further detailed explanation.
Extremely shown in Figure 7 like Fig. 1, the loading support that a kind of clamp device of rubber bushing rigidity test, this device comprise clamp system, are located at the base 8 of clamp system bottom and are located at clamp system top.Wherein, the clamp system adjusting screw(rod) 2 and setting nut 3 that comprise the clamp arm 1 of a pair of movable adjusting and be used to regulate distance between two clamp arms 1; Be specially at two clamp arms, the 1 upper and lower screw hole that all has, pass screw hole through two adjusting screw(rod)s two clamp arms are coupled together, be provided with setting nut at the adjusting screw(rod) two ends and fix.In order to guarantee that rubber bushing 6 is fixedly clamped and has preferably stability; On clamp arm 1, be provided with the groove 10 that clamps rubber bushing 6 usefulness; Groove cross section on the clamp arm 1 is an isosceles triangle, and the parallelogram that the groove through two clamp arms constitutes clamps rubber bushing is stable.
Slot opening size between two clamp arms 1 is regulated through adjusting screw(rod) 2 and setting nut 3.For the precision that improves adjusting and the stability of clamping; Be provided with lower convex platform 11 in clamp arm 1 bottom; Be provided with dragging track platform 7 on base 8 tops; Dragging track platform 7 is provided with the dragging track 70 suitable with lower convex platform 11, and its dragging track 70 is a rectangular recess, and is fixing through two second bolts 14 between lower convex platform 11 and the dragging track platform 7.Further, on clamp arm 1, be provided with convex platform 12, convex platform 12 is enclosed within the circular orbit 4 that is located at clamp arm 1 top, and is fixing through two first bolts 13 between circular orbit 4 and the clamp arm 1.
In order to improve the versatility of base; Reduce cost, dragging track platform 7 is detachable on base 8, promptly on dragging track platform 7, is provided with the locating slot 71 with dragging track 70 right-angled intersections symmetry; Base 8 is provided with location-plate 80, described locating slot 71 and location-plate 80 interference fit.
Preferably, loading support is that U-shaped loads support 5, loads between support 5 openends at U-shaped and is provided with support bracket bolt 50, and support bracket bolt 50 passes the endoporus of rubber bushing 6, and support bracket bolt 50 two ends are fixing through support nut 51.Wherein, The gap that U-shaped loads on support and the clamp system vertical direction should be according to the maximum displacement decision of rubber bushing assembly rubber; U-shaped loads support and requires the big 10-15mm of maximum displacement than rubber bushing assembly rubber with gap on the clamp system vertical direction, prevents in the process of the test that U-shaped loads support and clamp system interferes phenomenon in vertical direction.U-shaped loads support and clamp arm is 5-8mm along the gap on the rubber bushing central axial direction; If excesssive gap; When the test imposed load strengthens suddenly; The rubber bushing assembly possibly move along axis direction, does not stop to have the risk that the rubber bushing assembly takes off from the groove of two clamp arms if there is U-shaped to load support; If the gap is too small, can cause U-shaped loading support and clamp arm interfering along rubber bushing assembly central axial direction, test can't be carried out.
In order to save cost, be convenient to buying, bolt, the big ting model reference line industry standard of nut and national standard are carried out.
In the present invention, earlier rubber bushing is put into the parallelogram groove that constitutes between two clamp arms, regulate upper and lower two adjusting screw(rod)s and four setting nuts then, rubber bushing is fixed between two clamp arms; On the convex platform that circular orbit is enclosed within two clamp arms, be assembled together, circular orbit fixed through two first bolts; Lower convex platform with two clamp arms is placed in the dragging track on the dragging track platform again, is fixed up through two second bolts and lower convex platform; Dragging track platform and base are coupled together through location-plate and locating slot interference fit, base is arranged on the testing table; At last; The support bracket bolt that U-shaped is loaded support passes the endoporus center of rubber bushing; The two ends of support bracket bolt are fixed through the support nut; U-shaped loads the support upper end and is connected with the load maintainer of testing equipment, U-shaped loading support with respect to clamp system, rubber bushing, base can be up and down.During test, can measure rubber bushing through the testing equipment sensor is load-deflection curve at the force-displacement curve of loading direction, and this clamp device also can be used for the bench test and the long duration test of rubber bushing simultaneously.
Rubber bushing rigidity test for different size; Particularly rubber bushing outer ring radius change little (± 10mm) time,, regulate the distance between two clamp arms through adjusting adjusting screw(rod) and the setting nut between two clamp arms; And then adjustment is used to clamp two slot opening sizes on two clamp arms of rubber bushing; The rubber bushing rigidity test that satisfies different size clamps requirement, does not need jig design again, thereby practices thrift experimentation cost and reduce the test period.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
