Abstract

The utility model discloses a novel four-axis numerical control barking machine. A Z-axis assembly is fixed on a support and perpendicular to the upper portion of a workpiece platform, a sliding part of the Z-axis assembly drives a spindle assembly to perform vertical movement, a sliding seat is arranged under a workpiece platform and located on a machine tool base, and horizontal right-left motion, horizontal front-back motion and rotary motion of a workpiece are achieved under the joint effect of the sliding seat and a clamping mechanism. A cutting tool is driven by the spindle assembly to perform vertical motion, and accordingly four-axis stereoscopic rotary processing of the workpiece is achieved. The Z-axis assembly bears the spindle assembly, transmission rigidity is prevented from being reduced due to over loading of the spindle assembly when the Z-axis assembly moves horizontally and transversely, a phenomenon that batches of products are scrapped due to step failing in the processing process is avoided, the processing accuracy and the reliability of batches of processed products are improved, and loading of the numerical control barking machine is reduced. By means of matched processing of multiple spindles (cutter rests), the number of processed workpiece is increased, and productivity of enterprises is improved.
