Accompanying drawing explanation
Fig. 1: the utility model direct connection mechanical type machining center belt shaft structural representation.
Wherein: number in the figure, 1 is rotating shaft, and 2 is protecgulum, and 3 is front sealing gasket, and 4 is housing, 5 is pulling claw, and 6 is dish spring adjusting pad, and 7 is dish spring, and 8 is pull bar, and 9 is rear sealing gasket, 10 is locating piece, and 11 is connector, and 12 is pull bar coupled axle-pin, and 13 is shaft coupling output, and 14 is pull bar adapter sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.
As shown in Figure 1, the utility model is a kind of direct connection mechanical type machining center belt shaft, comprise the machining center belt shaft that rotating shaft 1, protecgulum 2, housing 4 and connector 11 form, rotating shaft 1 hollow Matching installation has pull bar 8, at the spacing radial direction through hole Matching installation of epimere U shape, there is radially pull bar coupled axle-pin 12, these coupled axle-pin two ends and connector of pull rod 11 Matching installations, stage casing and pull bar 8 Matching installations; This rotating shaft upper end external diameter is provided with axial step structure matching shaft coupling output 13 is installed, be provided with the pull bar adapter sleeve 14 of dust seal simultaneously, between pull bar 8 and spring adjusting pad 6, be provided with dish spring 7, also be provided with front sealing gasket 3, rear sealing gasket 9 for sealed bearing, in the housing 4 one end couplings near connector 11, the locating piece 10 that air inlet is installed be set simultaneously.
Operation principle of the present utility model: after processing center machine tool starts, when motor is in running order, the rotation of motor shaft directly drives machining center belt shaft rotating shaft 1 moving by shaft coupling output, while needing tool changing, by the processing center machine tool arm of forging a knife, act on the power of connector 11 step surfaces, promoting connector 11 axis moves, drive rotating shaft 1 axis to move, the input of shaft coupling is separated with output, machining center belt shaft stops operating, under the effect of pull bar coupled axle-pin 12, the mobile pushing drawing rod 8 of connector 11 moves simultaneously, pulling claw 5 spreadings are realized loose cutter, after tool changing completes, the processing center machine tool arm of forging a knife departs from the contact of connector 11, under the active force of dish spring 7, pull bar 8 promotes the axial reset movement of rotating shaft 1, promote shaft coupling input and output 13 merging, machining center belt shaft normal rotation.Gases at high pressure enter connector 11 air flues by the pore of locating piece 10, through pull bar coupled axle-pin 12 air flues, arrive in pull bar 8, blow off rotating shaft taper hole madial wall dust when tool changing.
