Abstract
1389974 Cutting tools SANDCO Ltd 15 March 1973 [16 March 1973] 12560/73 Heading B3B A cutting tool comprises an insert receiving site in which a cutting insert 11 is removably clamped, the site having a bottom surface 12 and side supporting surfaces for the insert, one of the side supporting surfaces being disposed on movable member 16 which is reciprocatable along the tool body to feed a new insert from a magazine 30 on the tool body to the insert receiving site, the movable member actuating at the end of its feed movement clamping means to clamp the new insert in the site. The feeding of the new insert into the site automatically displaces the old insert from the site. The movable member is in the form of a lever 16 pivotable about a pin 17 and actuated by a rod 25 to which it is connected by a pin and slot arrangement 23, 24. In operation the bar 25 is displaced in a direction A which pivots the lever 16 to disengage the clamping surfaces 20, 21 and moves the lever parallel to the rod 25. This movement uncovers the magazine 30 which permits a new insert 35 to be moved by spring 31 into a feed position adjacent the surface 15 on the lever 16. At the same time the insert clamp 26 is released by pivoting of lever 42 to release the used insert. Movement of the lever 16 by displacement of the bar 25 in direction C pushes the new insert into the site and into engagement with the clamp 26 and also displaces the used insert. At the end of the feed movement the lever 16 is pivoted to engage the locking surfaces 20, 21 and a heel portion A3 attached to the bar 25 engages the lever 42 to actuate the clamp 26 to secure the new insert on the site. In the embodiment described with respect to Figs. 7-10 (not shown) the insert support surface and the bottom of the site is disposed at an angle of 30-70 degrees and the operation of the insert transfer in a member similar to that described above except that the bar 25 actuates a lever (47) having an insert abutment (15) and a slotted pin and link element (20, 23, 24) which by co-operation with surfaces (34), (21) permit the link assembly to pivot and effect a wedging action which is locked at the end of the insert feed movement of the bar 25 and lever 47 for providing a rigid support for the newly positioned insert. In both embodiments the magazine extends normally to the bottom of the insert site.
