Multi function grind gouge head
1). The head is composed by left/right move structure, vertical
rotation structure, horizontal rotation structure, pitch up
rotation structure, side swing anti jam structure, head frame, head
power assembly, root pass gouging wheel structure, weld pass
reinforced abrasive band device(abrasive band contact wheel,
tighten & side swing device), pneumatic constant pressure float &
lift up device, safety protection and dust collect cover and so on.
Head motor is variable frequency motor. Main shaft rotation speed
is stepless adjustable.
2) The head left/right move structure is composed by motor, tailor
made reducer, transverse slider & guiding rail structure. Its
function is to align or correct the grinding central line &
equipment central line after the head horizontally rotate 90
degree.
3). Head vertical rotation structure is composed by motor & worm
gear reducer, using to adjust the head grinding angle. Rotation
angle adjustable range is 0º～90º, suitable to grind at clock
12(6)~3 random position for big diameter work piece.
4). Head horizontal rotation structure is composed by slewing ring
& support rack. According to vessel inner/outer
longitudinal/circumferential seam situation, it could adjust the
head ±90º, make it suitable for diverse working condition for root
pass gouging & weld pass reinforcement grinding.
5). Head pitch up rotation structure is composed by branch beam,
worm gear reducer, chain sprocket transmission & lockup clamp
device and so on. Main function is to suitable for taper work piece
or the work piece inclined put.
6). Side swing anti jam structure is composed by parallel sliding
structure & related lockup device.During root pass gouging, by
situation of the root pass side displacement(when the rotator
without anti drift function), the abrasive wheel would move along
with the root pass displacement automatically under axial force
driving. This structure is using to keep the abrasive wheel from
jam & following dangerous situation may be happened. The lockup
device is to keep the grinding pass from displacement when working
on the fixed position.
7). Grinding wheel & abrasive band are using the same main shaft,
power driving system, constant pressure floating & liftup device.
Except above, the abrasive band also has tighten wheel, side swing
structure(the bank swing horizontally during grinding).Also, the
protective cover is different with grinding wheel.
8). The floating mechanism pressure is stepless adjustable under
the control system. Grinding pressure could be precisely set.
During grinding, the grinding head is under floating situation.
Grinding pressure is constant. Under situation of the irregular
work piece or abrupt surface change, the contact wheel could keep
constant pressure to maintain stable effective grinding.
9). The grinding head could rotate or tilt over at horizontal /
vertical direction, able to grinding multi form beveling
preparation. Such as twin V beveling. By using abrasive band, it
could polish the inner/outer surface of the tank. By using grinding
wheel, it could gouge the root pass or grinding the weld pass
reinforcement of the tank inner/outer longitudinal/circumferential
seam, and twin V beveling preparation of steel plate under flat
place. The abrasive band has side swing device, by which could
fully using the band , saving production cost.
