Specific embodiment：
As shown in figure 1, seat support bump test device, including support body 1, in described support body 1, level is provided with lifter plate 2,
Described lifter plate 2 two ends are bolted with leading screw 3, and the upper end of described leading screw 3 passes through support body 1 top to pass through sprocket wheel chain phase with motor
Even, it is provided with weight bag 4 below described lifter plate 2, above described lifter plate 2, is provided with weight bag 4 elevating mechanism, described elevating mechanism
Including the cylinder 5 being fixed on support body 1 top, the piston-rod end of described cylinder 5 is fixed with the first connecting plate 6, and described first even
It is provided with the second connecting plate 7 below fishplate bar 6, between described first connecting plate 6 and the second connecting plate 7, be fixed with pulling force induction apparatuss 8, institute
State and between the second connecting plate 7 and weight bag 4, be provided with slide bar 9, between described second connecting plate 7 and lifter plate 2, be provided with spring.
Specifically, described lifter plate 2 is further fixed on installing frame 10, described first connecting plate 6 two ends are fixed with first and lead
Post 11, described first guide pillar 11 top passes through installing frame 10 and support body 1 top, and this setting can ensure that weight bag in lifting process
4 will not produce and rock, and improve stability.
Specifically, the bottom of described leading screw 3 is equipped with mounting seat 12, and described mounting seat 12 is respectively and fixedly provided with the second guide pillar
13, described second guide pillar 13 is fixed through lifter plate 2 with support body 1 top.
Specifically, it is placed with multiple steel balls in described weight bag 4.
Specifically, described lifter plate 2 is further fixed on multiple push rods 14, this setting can prevent lifter plate 2 from preventing second
The depth that connecting plate 7 pushes, it is to avoid idle stroke.
Specifically, the top of described push rod 14 is provided with rubber round end, and this setting can protect the second connecting plate 7 on contact top
Rigid collision is avoided during bar 14.
Operation principle of the present utility model：Seat support is fixed on below weight bag 4, puts into steel ball, by pulling force in weight bag 4
Induction apparatuss 8 can be shown that weight bag 4 mass, and weight bag 4 is promoted to specified altitude assignment by cylinder 5 cooperation screw mandrel, then passes through gas again
Cylinder 5 plus screw mandrel form a downward power, so that weight bag 4 is pounded on seat support, and then fast lifting declines again again, so repeatedly grasps
Make for several times, whether qualified with the quality that detects seat support.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making creativeness
The every other embodiment being obtained under the premise of work, all should belong to the scope of this utility model protection.
