Summary of the invention
The object of the present invention is to provide a kind of combination reasonable, adopt the machining center machine main shaft of installing type structure.
For achieving the above object, the scheme that the present invention takes is: a kind of machining center machine main shaft, it comprises a core, axle bed, the axle core is by the 7014C bearing, 7012C bearing and axle bed combine, the drive end bearing bracket and first spacer are by the outer shroud packing of the bolt on the ring flange with the 7014C bearing, the interior ring of 7014C bearing is then by first locking nut, second spacer is fixed on the core, the outer shroud of 7012C bearing will not fix and interior ring by second locking nut, the first circle-arc tooth belt wheel, dust cap is fixed on the core, push rod is installed in an in-core, the pintongs pawl is installed under the push rod, push rod bears the upwards active force of dish spring by nut, pass to the pintongs pawl then, nut and the mutual tightening of the 3rd locking nut, the axle core is by the first circle-arc tooth belt wheel input torque, the first circle-arc tooth belt wheel, the second circle-arc tooth belt wheel are fixed on the core and are on second locking nut.
This machining center machine with main shaft compared with prior art, structure is more reasonable.It adopts the installing type structure, and is easy to assembly.The pintongs pawl is installed under the push rod, and push rod passes to the pintongs pawl then by the upwards active force of nut with the dish spring, realize spindle assemblies button broaching tool tool effect.When external force overcame disc spring force and acts on push rod, push rod moved down, and the pintongs pawl moves down, opens, and does not detain the broaching tool tool, plays loose cutter effect; When external force disappeared, push rod moved up, and moved, shrank on the pintongs pawl, played the broaching tool effect.Coding belt wheel on the second circle-arc tooth belt wheel and the lathe links, and in conjunction with relevant control, finally realizes functions such as main shaft orientation, rigidity tapping, and nut and the mutual tightening of the 3rd locking nut play locking effect.
