Falling unit；Two groups of columns are relatively fixed on two crossbeams of bottom bracket upper end, have horizontal operation platform, work between its underpart
Make being respectively fixed at two ends with of platform upper surface to be arranged in parallel and the V-type vertical with two opposite faces of two groups of columns props up bracer；Respectively
Group column upper end is fixed with entablature, is fixed with top between two entablatures, the top lower proper V mouth that two V-types are propped up bracer
Line；Work platforms lower center is fixed on the upper surface of the lowering or hoisting gear of work platforms.
It is further preferred that the lowering or hoisting gear of described work platforms includes the motor being fixed on bottom bracket bottom surface
External tooth gear with the screw thread that the screw thread of reductor, leading screw and interior pore area Yu leading screw matches；Gear is screwed on leading screw, outside it
Tooth is meshed with the output gear of reductor；Leading screw upper end is fixed on, by bearing, the leading screw installing hole that work platforms center has
In.This lowering or hoisting gear can drive the gradual rising of work platforms, progressively presses for workpiece hollow axle, until being bent by hollow axle
Producing crack, it is stable and reliable in work.
It is further preferred that the screw thread on described leading screw is trapezoidal thread, thread form angle 30 °, big footpath takes 60mm, and screw thread is worked as
Amount angle of friction 8.83 ° > lead angle 2.95 °.The internal and external threads of trapezoidal thread is adjacent to be difficult to loosen with the conical surface；Big footpath takes 60mm,
Leading screw is made to have higher crush resistance and shear resistant；Screw thread equivalent friction angle 8.83 ° > lead angle 2.95 °, self-locking performance closes
Lattice.Entirety is more safe and reliable.
It is further preferred that bottom bracket, work platforms, entablature, column, two pieces of V-types prop up bracer and top employing is firm
The material spent makes, and such as Q235A, is connected fixing each other by M10 bolt.Fixing reliable, it is difficult to loosen, support has good
Good rigidity and tensile strength, can either bear bigger shearing force, it is also possible to bears bigger the drawing produced in process of the test
Load, service life is long；Device each parts reliable pretension and connection are effectively ensured.
It is further preferred that present invention additionally comprises case, case is buckled in bottom bracket, work platforms, entablature, two groups
Often on the column of group more than two, two pieces of V-types prop up bracer, top and work platforms lowering or hoisting gear forms single unit system；Cover
Shell front has glass window, side to have workpiece import.Single unit system is enclosed in case, can prevent test burst apart chip wound
People, uses safer.
During use, being placed in by hollow axle workpiece in the V mouth that two pieces of V-types prop up bracer, the lowering or hoisting gear band of work platforms is started building
Making lifting platform, at the top friction welding seam just withstanding on hollow axle, work platforms slowly rises, top extruded hollow axle, directly
It is deformed under top effect to hollow axle, and then produces crack, whether be positioned at commissure by observation crack position and enter
And judge whether the performance of this friction welding (FW) reaches requirement.Motor rotating speed of the present invention is adjustable, and test efficiency is high；Not sensing
Device, so being not easy destructive test equipment, space occupancy rate is little, simple, convenient, quick.Single unit system is enclosed in case
In, can prevent the test chip that bursts apart from hurting sb.'s feelings, use safer.
