A portable helical milling unit has a tool, an eccentric spindle, an outer sleeve, a sleeve housing, and a plurality of transmission mechanisms used to provide power. The eccentric spindle is detachably provided in an output section of the outer sleeve. Each of the eccentric spindle and the outer sleeve has a pre-set eccentricity. The tool is in connection with an eccentricity adjustment mechanism. The outer sleeve is installed in the sleeve housing. The outer sleeve is in connection with a first transmission mechanism and a third transmission mechanism. The eccentric spindle is in connection with a second transmission mechanism. All eccentric spindles have the same shape, can be installed in the outer sleeve and can be quickly replaced, so as to achieve precise and large-range adjustment of the eccentricity, thereby expanding the aperture range of processed holes, and improving processing quality and efficiency.
A portable helical milling unit comprising a tool, an eccentric spindle, an outer sleeve, a sleeve housing, and a plurality transmission mechanisms for providing power, wherein the eccentric spindle is detachably sleeved in an inner hole of output section of the outer sleeve, each of the eccentric spindle and the outer sleeve both has a pre-set eccentricity, the tool is in connection with an output side of the eccentric spindle, the eccentric spindle is detachably in connection with the outer sleeve, the outer sleeve is installed in the sleeve housing through a sliding bearing, an input side of the outer sleeve is in connection with a first transmission mechanism and a third transmission mechanism, an input side of the eccentric spindle is in connection with a second transmission mechanism, wherein the third transmission mechanism is used to drive the outer sleeve to rotate relative to the outer sleeve housing to enable the tool to rotate around an axis of outer cylindrical surface of the outer sleeve, the first transmission mechanism is used to drive the outer sleeve to move back and forth relative to an axis direction of the sleeve housing to achieve the feed motion of the tool, and the second transmission mechanism is used to drive the eccentric spindle to rotate so as to rotate the tool.
