Abstract

668,881. Drilling; work-holders; machine tool details. LAWRENCE, J. W., and ADCOCK, G. Aug. 15, 1950 [Aug. 25, 1949], No. 22109/49. Classes 83 (iii) and 83 (iv). A drilling, piercing, &c. machine, comprises a work-holder 16 which can be positioned in two perpendicular directions by a spring-pressed plunger 28 mounted on a travel-plate 10 and cooperating with a series of apertures in a bar 30 secured to the bed 1 and a spring- pressed plunger 40 mounted on the work-holder and co-operating with a series of apertures in a bar 33 on the plate 10, and a tool-head 6 having at least one tool-spindle which can be fed axially towards the work. For drilling holes in a header-plate 21 for a heatexchange unit, a base-plate 1 is attached to a drilling machine having a lever-fed drill aligned with a bushing 7 carried on a frame 4. The slide 16 moves on ways 17 on the travelplate 10 which itself moves on roller-tracks 11 on the base 1 and is guided by a T-projection 13. The work 21 is clamped at 19 to the slide 16 which is positioned by a peg 39 mounted eccentrically on the plunger 40. When alternate rows of holes are to be similarly spaced on the workpiece the plunger 40 is rotated to position the peg 39 according to the spacing of the row to be drilled. A collar 42 depending from the bushing 7 prevents the work being moved from underneath the drill by contacting the clamp 19. The apparatus may be modified by providing the plungers on the indexing bars and the apertures on the moving members, and by having more than two different spacings for the rows of holes. Other applications include tapping, reaming, boring, piercing, blanking, forming and pressing.
