PROCESS OF MACHINING OF LONG-LENGTH PART AND GEAR TO SUPPORT PART DURING MACHINING IN MACHINE TOOL

摘要

FIELD: machine tool manufacture, supporting nonrigid parts which length exceeds working length of table of machine tool. SUBSTANCE: in agreement with proposed process end of part is mounted in supporting member and unmachined end of part is fixed in clamping member 12 placed on mobile table 9 of machine tool. After machining of part 11 over first section of length, part is released out of clamping member 12 which is then moved together with table 9, part being immobile, in direction opposite to direction of working feed of table 9. Part is again cramped in clamping member 12 and next section of length is machined. Gear for implementation of process has mechanism moving supporting member made in the form of rotary bracket 1 set immobile under suspended state in guides 2 of yoke 3 of machine tool. Supporting member is in carriage 6 that is mounted for movement in vertical guides 5 of bracket and fixing between template 8 anchored on table 9 and adjustable rest 10 set on bracket 1. EFFECT: improved operational efficiency of gear. 2 cl, 6 dwg
