Frictional force between the No.1 friction plate 45 and No. two friction plates 47 of number shaft upper end becomes smaller, and avoids No.1 shaft upper end pulling force
It is excessive, it avoids No.1 shaft and is bent, improve the service life of No.1 shaft.
As shown in figure 5, the No.1 polishing rack 4 is equipped with fan 49, fan 49 passes through the maximum No.1 friction plate of radius
45 drivings, the No.1 polishing rack 4 between fan 49 and fixed frame 6 are equipped with heat release hole.The rotation of fan 49, so that fixed frame 6
In air be discharged from heat release hole under the action of fan 49 so that realize airflow in fixed frame 6, so that fixed
Heat in frame 6 is discharged, and avoids No.1 friction plate 45 and No. two friction plates 47 overheat, improve No.1 friction plate 45 and two
The service life of number friction plate 47.
Concrete operations process is as follows:
When work, stainless steel tube to be polished is clamped by fixture, by No.1 cylinder 21 control No.1 polishing rack 4 with
The distance of stainless steel tube makes No.1 sanding belt 44 contact stainless steel tube, then controls No. two cylinders 51 and make on No. two polishing racks 5
No. two sanding belts 52 contact stainless steel tube, at this point, by No.1 motor drive stainless steel tube rotation, it is positive and negative by No. two motors
Turn so that No.1 sliding block 12 moves back and forth, so that mounting rack 2 moves back and forth, so that each position of stainless pipe is beaten
Mill drives No.1 shaft and No.1 friction plate 45 to rotate, 62 squeeze adjustments ball of crushing block by No. three motor rotations in the process
48, so that adjusting ball 48 squeezes No. two friction plates 47, so that No. two friction plates 47 compress No.1 friction plate 45, No. two frictions
Piece 47 drives No. two shafts 46 to rotate under the driving of No.1 friction plate 45, so that No.1 sanding belt 44 rotates, No. two bands
So that No.1 friction pulley rotates, the power on No.1 friction pulley is rubbed wheel 42 by No. two for rotation under the action of No.1 sanding belt 44
It wipes wheel to be transmitted on No. three friction pulleys, so that No. two sanding belts 52 of No. three friction wheel drives rotate, so that No.1 sanding belt
44 polish to the weld seam of stainless steel tube with No. two movements of sanding belt 52, improve the grinding efficiency of stainless steel tube, together
When 44, No. two sanding belts 52 of No.1 sanding belt are contacted with stainless steel tube chance it is identical, reduce No.1 sanding belt 44 with
The abrasion of No. two sanding belts 52, improves the service life of No.1 sanding belt 44 and No. two sanding belts 52, when polishing, passes through control
The movement of No.1 cylinder 21 and No. two cylinders 51 can adjust No.1 sanding belt 44, two between sanding belt 52 and stainless steel tube
Distance, so that the precision of stainless steel tube polishing is adjusted；Meanwhile when one side weld bulge of stainless steel tube is larger
When, stainless steel tube squeezes No.1 sanding belt 44, so that No.1 sanding belt 44 pulls No.1 belt wheel 41 and No. two shafts 46, to make
Obtaining No. two shafts 46 drives adjusting balls 48 to move right, so that the pressure of 62 pairs of crushing block adjusting balls 48 reduce, so that two
The pressure that number friction plate 47 is subject to reduces, so that the frictional force between No. two friction plates 47 and No.1 friction plate 45 reduces, No. two
The driving force and revolving speed that friction plate 47 is subject to reduce, so that the revolving speed of No. two shafts 46 and No.1 belt wheel 41 reduces, No.1
The movement velocity of sanding belt 44 and No. two sanding belts 52 reduces, and avoids stainless steel weld joint and excessively polishes, after improving polishing
The quality of stainless steel tube；In the process, the movement of No.1 motor, No. two motors, No. three motors, No.1 cylinder 21 and No. two cylinders 51
It is controlled by controller, the presence of controller makes whole device more intelligent, improves the grinding accuracy of stainless steel tube.
