The present application relates to the technical field of double-shaft
numerical control lathe, in particular to a
numerical control lathe double-main-shaft
butt joint tool arrangement structure, which comprises a mounting base and a tool arrangement piece arranged on the mounting base, a tool rest is detachably connected to the tool arrangement piece, an adjusting
assembly is arranged inside the tool rest, and an elastic
washer is sleeved on a
fastener; the bottom protrusion of the
fastener connected to the tool rest is slidably installed into a groove arranged on the tool arrangement piece, the
fastener is pre-tightened to compress the elastic
washer when reaching a suitable position, the fastener is not completely tightened, the elastic
washer is in contact with the groove to fix the tool rest at this time, the tool rest is allowed to be finely adjusted under the premise of keeping stable, then the adjusting
assembly is pressed to make it longitudinally displace, the bottom adjusting component is in contact with the tool arrangement piece when the limiting
assembly limits it, then the adjusting assembly is rotated to cooperate with the tool arrangement piece, and the tool rest is driven to be finely adjusted.
