Luthra Hydro Pneumatic Industries
is proud to present a special purpose penumatic machine for assembly
shop which uses a unique system that checks the dimensional accuracy
of the male component to be press fitted into the female cavity and
after testing for dimensional tolerance subsequently presses the same.
The machine has been developed for M/s. Bharat Gears, Thane. A Steel
ball has to be press fitted into the cavity of the gear assembly.
The ball should withstand the oil pressure in the cavity to upto 4000
bar pressure and as a result needs to be initially tried to be inserted
into the cavity at 750 kgf for 15 seconds. The force and time both
are adjustable. If the ball slips into the cavity, the gear assembly
is rejected. If the ball can withstand the load, then a force of 1.8
tonnes is applied on it, press fitting it into the cavity. The machine
is using a three stage tandem pneumatic cylinder and has got fully
automatic electronic controls.
The pressure setting can be varied and the pressing force achieved
can be upto 21 tonnes. The force and pressure reading is provided
on the machine for achieving the exact testing criteria. |
