Pushing block 213 is fixed on impeller-hub 21 by nut 214；Secondly, staff is according to practical condition by changing flange
212 on two-way cylinder 12 amount of screwing, and then change position of the top pillar 41 on pushing block 213, two-way cylinder 12 avoided to bear
Biggish outer load realizes relative position of the top pillar 41 on pushing block 213 using the horn-like structure of pushing block 213, in turn
Realize the propulsion and retrogressing of top pillar 41；Finally after the completion of to above-mentioned adjustment, scale work can be carried out, is used in the device
After a period of time, the second locking nut 214 is loosened, pushing block 213 is rotated a certain angle, the effect of itself and top pillar 41 is changed
Face avoids the change generated and the acting surface bears the promotion of top pillar 41 always by regularly change to the acting surface
Shape ensure that the stability and accuracy of scale.
The apparatus structure in the present invention is simple, accurate positioning, the resultant force that the setting of pushing block carries two-way cylinder point
At the radial force along impeller-hub and the axial force along impeller-hub, the resultant force for avoiding traditional cylinder carrying all acts on solution
Defect on cylinder impeller-hub, greatly reduces the axial force of two-way cylinder carrying, while avoiding two-way cylinder in band steel plate
Multifrequency Secondary Shocks under and generate rebound phenomenon and fatigue phenomenon, substantially increase two-way cylinder service life and precisely
Degree, ensure that the shear precision with steel plate；The setting of multiple support bases and sliding bearing in the device, ensure that the device
Strength and stability；Also with the change of screw amount of the flange on two-way cylinder, the fine tuning to pushing block position is realized
Bear the outer adjustment carried with to two-way cylinder, adapt it to the different conditions of production, substantially increase the device adaptability and
The precision of scale, while the pushing block that can be rotated avoids the lasting rolling on pushing block same position of top pillar, into
And the deformation for avoiding pushing block under top pillar long term and generating, by regularly being adjusted to pushing block, Jin Erbao
The stability and accuracy of the device are demonstrate,proved.
