The utility model content
The utility model technical issues that need to address provide a kind of vertical machining centre mainshaft mechanism, it mainly is that to solve the main axle structure that existing in prior technology machining center machine uses comparatively complicated, manufacturing cost is not high, and during its inflation clamping cutter, chucking power is not enough, the technical problem that causes that cutter comes off easily etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Vertical machining centre mainshaft mechanism of the present utility model, comprise sleeve, sleeve ends is connected with end cap, be provided with housing in the sleeve, it is characterized in that described housing upper end is connected with belt wheel by key pin, the housing lower end has the taper hole that can insert cutter, enclosure interior is provided with axle center moving up and down, inside, axle center is provided with the last inlet channel and following inlet channel that interconnects, and last air inlet channel diameter is greater than following inlet channel diameter, but the lower end, axle center is connected with the clamping device of clamping cutter.Twine belt on the belt wheel, belt connects the belt pulley on the motor, like this behind the electric motor starting, by belt transmission power, belt wheel drives the housing rotation, and housing drives the axle center rotation, drives motion of main shaft through the pneumatic loose machine drawing structure above the main shaft, thereby the cutter of clamped device clamping promptly is rotated, and at this moment just can process workpiece.The last air inlet channel diameter of inside, axle center is greater than following inlet channel diameter, can be so that gas be shunk by channel diameter suddenly behind admission passage, so the strength of its inflation is more sufficient, can give clamping device bigger chucking power, make the cutter difficult drop-off.
As preferably, described clamping device includes the pintongs pawl, and the lower end of pintongs pawl is provided with corpus unguis, and pintongs pawl upper end is provided with coupler body, and the lower end, axle center is provided with the step that can be hooked by coupler body.When the axle center moved down, the pintongs pawl opened, and can allow cutter insert in it, when the axle center moves up, the lower end, axle center step be hooked on the coupler body of pintongs pawl because lever principle, promptly draw in to the centre lower end of pintongs pawl, thus clamp-on tool.The pintongs pawl also can replace with the mechanism that other ball type etc. can the clamping cutter.
As preferably, be provided with bearing between described sleeve and the housing, housing outer surface is provided with spacer ring, spacer ring by locking nut with bearing fixing.Bearing is located at the two ends and the middle part of sleeve, and two ends are respectively established two, and the middle part is set up one.
As preferably, described axle center is connected with reseting spring leaf, and reseting spring leaf is located in the gap between housing and the axle center.Reseting spring leaf can be said the axle center pop into position after the work, and reseting spring leaf also can other mechanism that axle center is resetted.
As preferably, be provided with sealing ring between described pintongs pawl upper end and the axle center, prevent that gas from revealing away between pintongs pawl upper end and axle center.
Therefore, it is comparatively simple to the utlity model has the main axle structure that the machining center machine uses, and manufacturing cost is lower, and inside, axle center establishes the two-part inlet channel, and when inflation clamping cutter, chucking power is bigger, characteristics such as can not cause that cutter comes off.
