Portion is connected with chassis, and barrel is arranged in outer barrel, and barrel outer wall is cased with ring flange, and long axis direction of N number of guide rail along barrel is set,
Outer tube inner wall is evenly distributed on, the ring flange coordinates with guide clearance, slided along guide rail；M buffer mounting stand is along outer barrel
Circumferentially it is uniformly distributed, and is connected with outer barrel, sleeve outer wall is provided with P journal stirrup, and P=M, sleeve at the top of barrel with being connected, and sleeve position
Above outer barrel, the journal stirrup of buffer one end to be measured and sleeve is connected, and the other end is connected with buffer mounting stand.
The bottom plate of the buffer mounting stand is mounting surface, and mounting surface band is cambered, is coordinated with outer barrel；Buffer mounting stand
Journal stirrup is provided with, journal stirrup is provided with through hole, is connected with one end of buffer to be measured, and reinforcement is provided between journal stirrup and bottom plate.
The barrel is cylinder, and top has an annular boss, is coordinated by boss and sleeve gap, by pressure transmission
To buffer to be measured.
The outer barrel is cylinder, and guide rail is avoided on outer barrel and buffer mounting stand opens some lightening holes.
Compared with prior art, its remarkable advantage is the utility model：（1）Simple and reliable for structure, production cost is low, and
And preferably simulate the impact condition of emitter；（2）The device can be installed slow in most of length and diameter range
Device is rushed, there is well adapting to property.
