Scissor-like jack 7 and common similar with car jack structure, comprises framework 70 and is arranged on the loading acme thread bar 71 on framework 70, one of difference is that framework 70 is welded and fixed by the second worm gear 60 of mounting bracket 72 and the second worm and gear group 6.Mounting bracket 72 comprises that a pair of lug 720, two lugs 720 that are provided with pin-and-hole are parallel to each other, and its spacing just in time can hold the projection 53 of fixed support 5.When the second worm and gear group 6 is assembled with fixed support 5 and mounting bracket 72, projection 53 is between two lugs 720, the second worm-wheel shaft 602 is through the side mounting hole 530 of projection 53 and the pin-and-hole of two lugs 720, the second worm gear 60 is welded and fixed with mounting bracket 72, and is meshed with the second worm screw 62 being arranged on fixed support 5.Mounting bracket 72 is fixedly installed on framework 70.
Should be noted that, although the utility model embodiment adopted use to general car with the similar structure of car scissor-like jack, on the loading trapezoidal screw with car lifting jack, only have a thrust bearing, only can bear unidirectional load, only can pressurized, can not tension.For the scissor-like jack 7 in the utility model embodiment can be loaded by tension compression bidirectional, the present embodiment design improves loading acme thread bar 71, as shown in Figure 6.By loading the shaft shoulder on acme thread bar 71 and with the set nut 711 that loading acme thread bar 71 welds together, two thrust bearings 712 being fixed on to pin 710 both sides, and then realize scissor-like jack 7 and can draw, press biaxial loadings by loading the rotation of acme thread bar 71.
Introduce the course of work of the utility model embodiment shutter member stiffness test charger below.First, as shown in Figure 1, the present embodiment defines X, Y, tri-of Z are axial, and wherein, the first boss 22, the first adjusting screw(rod) 101, the second worm-wheel shaft 602 are X axis; The first worm screw 41, power sensor 8, loading head 9 are all positioned at Y-axis; The second boss 22, the second adjusting screw(rod) 102, the first worm-wheel shaft 401, the second worm screw 62, loading acme thread bar 71 are all positioned at Z-axis direction.On worktable, base 1 is fixing, position and the direction that by worm screw, can realize loading head 9 regulate:
(1) X axis rotates: second worm screw 62 of rotating the second worm and gear group 6, because the second worm screw 62 is meshed with the second worm gear 60, the rotation of the second worm screw 62 will drive the second worm gear 60 to rotate around X-axis (now concrete turning axle is the second worm-wheel shaft 602), and scissor-like jack 7 is fixedly connected with the second worm gear 60, therefore scissor-like jack 7 and the loading head 9 that is connected on scissor-like jack 7 also rotate around X-axis thereupon, have realized loading head 9 rotation in the X-axis and have regulated.
(2) Z-axis direction is rotated: rotate the first worm screw 41 of the first worm and gear group 4, because the first worm screw 41 is meshed with the first worm gear 40, the rotation of the first worm screw 41 will drive the first worm gear 40 to rotate around Z axis (now concrete turning axle is the first worm-wheel shaft 401); The second worm and gear group 6 is arranged in the first worm and gear group 4 by fixed support 5, scissor-like jack 7 is fixedly connected with the second worm gear 60 again, therefore the second worm and gear group 6, scissor-like jack 7 and the loading head 9 that is connected on scissor-like jack 7 also rotate around Z axis thereupon, have realized the rotation of loading head 9 in Z-axis direction and have regulated.
(3) Y-axis is rotated: directly rotate loading head 9, but in the present embodiment without practical significance, repeat no more.
(4) X axis translation: rotate the first adjusting screw(rod) 101, because the first threaded hole 21 of the first adjusting screw(rod) 101 and slide 2 forms, be threaded, the rotation of the first adjusting screw(rod) 101 will drive slide 2 on base 1 along X axis translation (being the first boss 10 on base 1 and the slip between the first dovetail groove 20 on slide 2).Slide block 3 is arranged on slide 2, and the first worm and gear group 4, the second worm and gear group 6 and scissor-like jack 7 are directly or indirectly arranged on slide block 3, therefore scissor-like jack 7 and be connected to loading head 9 on scissor-like jack 7 also with slide 2 along X axis translation, realize loading head 9 translation in the X-axis and regulate.
(5) Z-axis direction translation: rotate the second adjusting screw(rod) 102, because the second adjusting screw(rod) 102 and the second threaded hole 320 on slide block 3 form, be threaded, the rotation of the second adjusting screw(rod) 102 will with movable slider 3 on slide 2 along Z-axis direction translation (being the second boss 22 on slide 2 and the slip between the second dovetail groove 300 on slide block 3).Slide block 3 is arranged on slide 2, and the first worm and gear group 4, the second worm and gear group 6 and scissor-like jack 7 are directly or indirectly arranged on slide block 3, therefore scissor-like jack 7 and be connected to loading head 9 on scissor-like jack 7 also with slide block 3 along Z-axis direction translation, realize the translation of loading head 9 in Z-axis direction and regulate.
(6) Y-axis translation: rotation loads acme thread bar 71, and loading head 6 is along Y-axis translation, identical with load operation.
As from the foregoing, the shutter member stiffness test charger that the utility model provides, use two groups of worm and gear multiple degrees of freedoms to regulate loading direction, worm drive by adjusting screw(rod) regulate loading position, these two kinds of gear trains all can be realized self-locking, and compact conformation, makes to regulate easy for installation, takes up room little.
The utility model is mainly used in vehicle body shutter member stiffness test, but also can be used for the frequent occasion of adjusting loading position and loading direction of other needs, can effectively save the charger Installation and Debugging time, improves test efficiency.
Above disclosed is only the utility model preferred embodiment, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
