Abstract
847,692. Machine-tool details. BIRWELCO Ltd. Jan. 2. 1959 [Jan. 7, 1958], No. 572/58. Classes 83 (3) and 83 (4). Apparatus for performing repetitive operations on a cylindrical workpiece automatically, e.g. drilling holes or welding studs on the work periphery, in which the work is moved about its longitudinal axis and also fed axially, comprises a base 5, Fig. 1, a runway 6 supporting the ends of the work by supports 7, a device 15 for rotating and feeding the work axially, and a clamp 12, operable when the feeding-device is released and the welding equipment 29 is operating. The feeding-device comprises shoes 16, Fig. 4, connected to arms 15 which grip the work 8 when a pneumatic double-acting cylinder 17 moves the arms about a pivot 15a. A similar cylinder 22 is connected to one of the pins 18 on the arm 15 by a yoke 20, the pins being guided in plates 23 adjustably bolted to plates 19, the latter being adjustable to the vertical so that, when the feeding-device is rotated by the cylinder 22, it will also move axially. The clamping-device comprises shoes 13, Fig. 3, connected to arms 12, which clamp the work when a pneumatic cylinder 14 is' actuated, the device being fixed against rotation. Tn operation, the work 8 is supported by two sets of adjustable-rollers 10 secured to frames 9, cylinder 17 is actuated and the shoes 16 grip the work; the cylinder 22 is then actuated, thus turning the work and feeding it axially according to the setting of guide-strips 23 on plates 19. The cylinder 14 is actuated, and the work is clamped by shoes 13. Cylinders 17, 22, are then reversed to return the feeding-device to its initial position, and a stud is welded to the work. Cylinder 14 then releases the workclamp, and as the operations are repeated, the studs are welded to the work in a helical path. The pitch of the studs can be varied by adjusting the stroke of cylinder 22, or by limiting'the stroke by stops 31. The machine is automatically-controlled by a cam 26 driven by a motor 25 and controlling valves for cylinders 14, 17, 22, and for the operation of the tool &c. 29. The welding-machine may incorporate a vibratory feed-bowl 28 and a magazine 29 from which one stud is fed and arc-welded at each operation.
