Technical field
The present invention relates to a kind of timber process equipment, particularly relate to the concentric reducing round bur head unit that a kind of concentricity is convenient to control.
Background technology
Wooden boards has lightweight, the advantage such as strength ratio is high, good springiness, shock-resistant, unity and coherence in writing rich palette is attractive in appearance, handling ease, has resource regeneration simultaneously, and wooden boards all occupies an important position to the present from ancient times in national economy.Wooden boards processing industry is raw material with wooden boards, mainly mechanically processes.Existing timber rig is in the concentric circle holes drilling carrying out different depth and diameter, need successively difference drilling cuttings two holes, this just to need on same drilling machine more bit change or timber is moved to the drilling other drilling machines completing second hole, but this process is that more bit change or mobile timber or Middle Phase are all one period of considerable times for boring procedure itself.
Summary of the invention
For improving the concentric different diameter hole drilling efficiency of the above-mentioned type, the invention provides the concentric reducing round bur head unit that concentricity is convenient to control, the feature that when this device is holed according to timber, cutting force is little, drill bit and at least one milling cutter are arranged to one, complete the drilling cuttings processing of concentric different diameter hole macropore and aperture simultaneously.
For achieving the above object, the present invention achieves the above object by the following technical programs: concentricity is convenient to the concentric reducing round bur head unit controlled, comprise gear-box, drill jig, drill bit, at least one milling cutter presss from both sides, at least one milling cutter and planet circular system, described drill jig is held on drill jig, described milling cutter is clamped on milling cutter folder, described planet circular system comprises internal gear, at least one planetary gear, sun gear, sun wheel shaft, planet wheel spindle, described sun gear is concentric with internal gear, described planetary gear is between internal gear and the sun gear gear teeth, and with internal gear and sun gear gear teeth meshing, described sun wheel shaft is through sun gear centre bore, lower end is connected with the link of drill jig, one end of described planet wheel spindle is arranged in the centre bore of planetary gear by flat key, the bare terminal end that the other end and milling cutter press from both sides becomes to be clamped and connected, described internal gear is arranged in gear-box.
Arranged by this kind, the torque Direct driver bit inputted by sun gear rotating shaft can be made, and torque is delivered on sun gear simultaneously, the rotation of sun gear drives planetary gear rotation, thus the planet pin be connected in described center planetary gear hole rotates together with same angular velocity with planetary gear, the milling cutter folder be connected on planet pin rotates with identical angular speed with planet pin with milling cutter simultaneously, and milling cutter completes rotation and the revolution around sun gear.
As preferably, also comprise planetary wheel carrier, described planetary wheel carrier end is matched in clearance respectively by axle sleeve and planet wheel spindle, middle part by arrange axle sleeve and sun wheel shaft be matched in clearance.
This setting can make the relative position relation of each planetary gear fix, and namely when the power that each milling cutter is delivered on each planetary gear is uneven, each planetary gear is appointed so with identical speed rotation and revolution.
As preferably, also comprise gear case gland, described gear case gland is bolted the upper surface being fixed on gear-box.This arranges the relative position limiting internal gear and gear-box.
Further, described planetary gear at least two, and that to be distributed on sun gear center be the center of circle is circumferentially same.This kind is arranged, and makes each milling cutter in machining, can reduce the phenomenon of each planetary gear load distribution inequality in planet circular system as far as possible.
Further, described sun wheel shaft diameter of section is 13-20mm.Under meeting sun wheel shaft can transmit the condition of required torque, save material, and sun gear rotating shaft can be directly clamped on common drill bit folder.
Further, described sun wheel shaft all uses flat key to be connected with sun gear centre bore, planet wheel spindle with planetary gear centre bore, and described flat key is cup head flat key.The assembling of sun wheel shaft and sun gear centre bore, planet wheel spindle and planetary gear centre bore junction stated by this setting party's toilet.
Invention compared with prior art, has following beneficial effect:
Concentricity provided by the invention is convenient to the concentric reducing round bur head unit controlled, the feature that when holing according to timber, cutting force is little, drill bit and at least one milling cutter are arranged to one, complete the drilling cuttings processing of concentric different diameter hole macropore and aperture simultaneously, save existing timber rig when the concentric circle holes drilling carrying out different depth and diameter, need successively difference drilling cuttings two holes, to need on same drilling machine more bit change or timber is moved to the drilling other drilling machines completing second hole, shorten this time needed for type hole machined, enhance productivity.
