Angle drill centrally holed pressure plate - holds vertical rods on which slide and fixture housing run

摘要

The angular drilling machine has a supplementary appts. which involves a centrally holed pressure plate (1) surrounded by rubber, on which two or more vertical rods (3) are fitted. A slide (4) runs on the rods (3), as does also a housing (5) connected by a plate and in the centre of which is a hole (6) for location and fixture of the drill drive machine. On each vertical rod (3) and between the pressure plate (1) and the guide slide (4) is a spring spiral (7). Beneath the pressure plate (1) are two displaceable, counterposed fillets (8) which are guided by threaded pins in grooves on the plate (1) and fixed by means of wing screws (9).
