INSPECTION OF SPRING SEAT LIFT
Assembly of turret requires
careful attention to detail. Please
follow step by step procedure
given below :
17.1. Partial Assembly of
Spindle
17.11. Drum Cam Sub-assembly
(Fig 17.1) : Assemble all compo-
nents as shown in figure 17.1.
Screws (30) and (44) should be
tightened firmly after coating them
with anti vibration solution like Lock-
tite. Check for free movement of
sliding coupling rollers in drum cam
groove.
17.12 Indexing Gear Sub-as-
sembly (fig 17.2): Assemble all
components as shown in fig 17.2.
Tighten bolts (15) with a light force.
In case of models BTP-80 and BTP-
100, pinion assembly should also
be in place.
17.13 Assemble spindle, indexing
flange and fixed coupling (compo-
nents 31, 34, 27, 3, 33); and keep
this assembly in vertical position on
a table (fig 17.3). It is convenient if
the assembly could be clamped to
the table with the help of a plate as
shown in the drawing. If plate is not
available you may use tool disc in
place of the plate.
17.14 Place drum cam subassem-
bly on the spindle, and place thrust
bearing (9) and spring seat (10) in
position.
17.15 Inspection of spring seat
lift (fig 17.3): Hold sliding coupling
(4) by one hand to prevent its rota-
tion, and rotate drum cam gear (8)
by hand (fig. 3). Sliding coupling
will move up and down ; engaging
and dis-engaging with fixed and
indexing couplings (3 and 27). At
the end of downward stroke, spring
seat should lift up by 0.25 mm to
0.35 mm. This lift should be inspect-
ed by using a dial indicator. If the lift
is less, it should be adjusted by
grinding the bottom face of spring
seat (10). If lift is more, it can be
reduced by removing material from
the bearing seating surface of spring
seat 10.
