DETAILED DESCRIPTION
Referring now to FIG. 1, 2& 3 present invention is a fixture 7 adopted for
used on Machine tools.
The fixture for machine tools 7 is designed to hold the work piece 8 well
positioned as reference Surfaces given on work piece 8 & rigidity for machining
operation of casting 8. fixture for machine tools 7 comprise a base plate 1 having
a substantially flat top surface ‘A’ and bottom surface ‘B’, base plate made of mild
steel, surface ‘B’ of base plate rest on M/C bed D & clamped base plate A
through 2-C’ bore holes 9 made in base plate 1 on M/c tool bed.
Annexure‐II
Position pin 3 of made of Standard dowel, HRD & GRD 40-45 RC fixed
with base plate A to position the work piece 8 to get datum position for
machining.
Guide pin 4 are used to guide the work piece made of standard dowel pin,
HRD & GRD 40-45 RC fixed with the base plate 1. Work piece is clamped in two
points with two clamps of EN8 to securely hold the casting to avoid the vibration
on casting during machining.
Dialing face ‘C’ in base plate A used as a datum for the manufacturing of
fixture 7 to maintain the position of all the items as describe above & this dialing
face ‘C’ is also used to position the fixture when fixing on Machine tool bed. Allen
head screw 5, 6 are used to clamp the work piece on the fixture 7.
