Novel rigid universal cartridge for holding system

Abstract

In view of the foregoing, an embodiment herein provides a rigid cartridge for multiple and universal application of all machining processes. The rigid cartridge includes a cylindrical body, a guiding & locating body connected to bottom side of cylindrical body, and a combination screw having a left hand [LH] thread and a right hand [RH] thread, wherein the cylindrical body includes a flat for locking the cartridge with the cutter body by using a locking screw, wherein the combination screw is connected to the bottom end of said guiding & locating body. The LH thread is provided in cartridge side and RH thread is provided in cutter body side or vice versa. In the cutter body or boring bar, a slot is provided for enabling to rotate the combination screw in clockwise or anti-clockwise direction to move the cartridge in forward and backward direction.

I claim: 
     
         1 . A rigid cartridge for universal holding system, wherein the cartridge comprises of a cylindrical body, a guiding & locating body connected to bottom side of cylindrical body, and a combination screw having a left hand [LH] thread and a right hand [RH] thread, wherein said cylindrical body includes a flat for locking said cartridge with a cutter body by using a locking screw. 
     
     
         2 . The rigid cartridge as claimed in  claim 1 , wherein said cutter body is a milling cutter or a boring bar. 
     
     
         3 . The rigid cartridge as claimed in  claim 2 , wherein the combination screw is connected to the bottom end of said guiding & locating body. 
     
     
         4 . The rigid cartridge as claimed in  claim 2 , wherein a slot is provided in said cutter body for enabling to rotate said combination screw in clockwise or anti-clockwise direction to move said cartridge in forward and backward direction. 
     
     
         5 . The rigid cartridge as claimed in  claim 4 , wherein bottom surface of said slot is provided with marking in degrees for measuring/controlling the movement distance of cartridges. 
     
     
         6 . The rigid cartridge as claimed in  claim 2 , wherein a threaded locking hole is provided in said cutter body for locking said cartridge with said cutter body. 
     
     
         7 . The rigid cartridge as claimed in  claim 2 , wherein said LH thread is provided in said cartridge side and said RH thread is provided in said cutter body side or vice versa. 
     
     
         8 . The rigid cartridge as claimed in  claim 2 , wherein said combination screw is provided with a central hole for rotating said combination screw in a desired direction. 
     
     
         9 . The rigid cartridge as claimed in  claim 1 , wherein diameter of said guiding & locating is lesser than said cylindrical body for guiding said cartridge axially on accurate concentric pocket made in said body within 20 micron clearances. 
     
     
         10 . The rigid cartridge as claimed in  claim 8 , wherein said centre hole is provided at side or bottom portion of said combination screw in order to rotate the combination screw in a desired direction.
