Chapter 1. Mechanical description
Feed mechanism (Y axis) 311E and 311EL
1.
The driving gear
w
attached to the Y-pulse motor
q
oscillates the idle gear
e
.
2.
When the idle gear
e
oscillates, the Y-timing belt
y
moves forward and backward through timing pulley (A)
t
attached
to Y-pulley shaft (A)
r
.
3.
The belt holder
u
and the Y-driving shaft holder
i
which are fixed to the Y-timing belt
y
operate the Y-driving shaft
o
.
4.
The X-feed shaft support
!
0
and the X-feed shaft
!
1
are attached to the Y-driving shaft
o
. The presser arm assembly
!
2
is attached to the Y-feed bracket
!
3
.
5.
The Y-feed bracket
!
3
operates in the Y-direction (moves longitudinally) via the Cross roller
!
4
and the Y-feed guide
!

.
Feed mechanism (Y axis) 326E, 326EL
1.
When the Y-pulse motor
q
operates, its motion is transmitted to the driving gear
r
attached to the Y-driving gear shaft
e
via the coupling
w
.
2.
The driving gear
r
is engaged with the rack of the Y-driving shaft
t
, and the Y-driving shaft
t
moves back and forth.
3.
The work clamp arm assy
i
is attached to the Y-feed bracket
o
via X-feed shaft support 326
y
attached to the Y-
driving shaft
t
and the X-feed shaft
u
.
4.
The Y-feed bracket
o
operates in the Y-direction (back and forth) via cross roller 326
