Abstract
The utility model provides a dynamic balance system for a machining center high speed main shaft, which comprises a machining center high speed main shaft, and is characterized in that a dynamic balance ring is respectively fixed at three different positions on a machining center high speed main shaft neck; screwed holes are evenly arranged on the dynamic balance rings along the circumference, and an adjusting bolt is installed in the screwed hole according to requirements; and the dynamic balance rings are arranged on the front and the back end surfaces of a stator of the machining center high speed main shaft, and the back end of a back bearing. Reasonable quality is added at different angular positions so as to improve dynamic balance precision grade of the machining center high speed main shaft assembly, and meet the requirement of the dynamic balance precision of the main shaft.
Description
Technical field
The utility model relates to a kind of dynamic balance system that can improve machining center high-speed main spindle dynamic balance accuracy.
Background technology
The rotating speed of machining center high-speed main spindle generally requires all more than 12000 rev/mins, and accelerate to 12000 rev/mins and decelerate to 0 time requirement all in 1 second from 12000 rev/mins from 0, thereby require the dynamic balance accuracy grade of machining center high-speed main spindle very high.The dynamic balance accuracy of present machining center high-speed main spindle is certain, can not adjust.
Summary of the invention
The purpose of this utility model is to provide machining center high-speed main spindle dynamic balance system to existing, can adjust the dynamic balance accuracy of machining center high-speed main spindle easily and efficiently.
For this reason, the technical solution of the utility model is: machining center high-speed main spindle dynamic balance system, comprise the machining center high-speed main spindle, and it is characterized in that: be fixed with the transient equilibrium ring respectively on three diverse locations on the work in-process heart high-speed main spindle axle journal; Be processed with the threaded hole that is uniformly distributed along the circumference on the described transient equilibrium ring, the adjustment screw is installed in threaded hole as required.
To further improvement in the technical proposal, described transient equilibrium ring is located at the stator front/rear end place and the rear bearing rear end of machining center high-speed main spindle.
Beneficial effect: when doing machining center high-speed main spindle dynamic balance running, can in different transient equilibrium ring screws, suitably install and adjust screw, thereby increase rational quality according to balance, can reach the purpose that improves main shaft component dynamic balance accuracy, improve dynamic balance accuracy.
Description of drawings
Fig. 1 is the structural representation of the utility model utility model.
Fig. 2 is the structural representation of transient equilibrium ring.
Embodiment
Shown in Fig. 1,2, description the utility model is as follows: before and after the stator 2 of work in-process heart high-speed main spindle 1, the rotor and mainshaft rear bearing 4 rear ends respectively increase a transient equilibrium ring 3 respectively, threaded hole 7 of uniform M5 all on each transient equilibrium ring 3, when doing the main shaft dynamic balance running, can be according to balance, the screw 6 of adjusting M5 is installed in different transient equilibrium ring screws, can reach the purpose that improves main shaft component dynamic balance accuracy, wherein transient equilibrium ring 3 is installed on the machining center main shaft by interference fit.
