DEVICE FOR CLAMPING OF NEEDLE BOARD TO NEEDLE CARRIER WITH NEEDLE PUNCHING AND PRE-PUNCHING MACHINES

摘要

The device is designed for clamping needlethe plate (20) to the needle beam (14) by means ofat least one lever fixture,which consists of an adjustable spacer (8)articulated by at least two two-armlevers (1). Every two-arm lever(1) is slidably mounted at the same timerotatably on a fixed pin (2) and another joint(17) connected to the yoke (5). Caliper (5) tit is slidably and simultaneously rotatably attached toa fixed pin (7) and provided at the free enda side protrusion (12) oppositea recess is formed on the side of the needle board (20)(11). Fixed pin (2) and fixed pin(7) is fixed to the holder (4) which isfastened to the needle beam (14). Changethe position of the adjustable spacer (8) is realizedwith clamping screw (9) and nut(10) or pneumatic or pneumatic. hydrauliccylinder, etc.
