Description
Technical field:
The present invention relates to a kind of large-size machine detachable-shaft dynamic balancing tooling devices.
Background technique:
With the development of nuclear power technology, the requirement for the process and precision of motor all parts is also higher and higher,
The quality of each component processing of motor can directly reflect the overall performance of motor, and wherein the dynamically balanced precision of detachable-shaft is got over
Height, more can increase the whole dynamic balance stability of motor, and traditional dynamic balancing mode can not meet the high-precision of nuclear power technology
It is required that and the dynamically balanced mode of tradition easily make balance deviation, cause workpiece to be scrapped, therefore need a kind of new fitting device.
Summary of the invention:
The dynamically balanced large-size machine detachable-shaft of motor detachable-shaft can be smoothly completed the object of the present invention is to provide one kind to move
Balance tooling device guarantees the dynamically balanced precision of detachable-shaft, to improve the overall precision of motor manufacturing.The present invention is using as follows
Technical solution: a kind of large-size machine detachable-shaft dynamic balancing tooling device is made of, 1 one end of axis axis 1, conical ring 2 and fastening bolt 3
It is machined with the taper axle journal 5 matched with 4 internal diameter end chamfer angle of detachable-shaft；1 other side of axis has raised major diameter 6, protrusion
The convex portion of major diameter 6 is uniformly distributed threaded hole 7 on the certain pitch circle in side on the outside, and fastening bolt 3 is fitted on threaded hole 7,
The protrusion outside of raised major diameter 6 has transition axis shoulder, and axis 1 is slidably matched with conical ring 2.
Conical ring 2 is fitted on the transition shaft shoulder of axis 1, and processing is for across tight on the pitch circle identical as the raised major diameter of axis 1 of conical ring 2
The through-hole of fixing bolt 3.
Fastening dress bolt 3 is standard bolt, and fastening dress bolt 3 passes through the threaded hole on through-hole and 1 boss of axis on conical ring 2
It is equipped.
The working principle of the invention:
The present invention penetrates axis in detachable-shaft plus chamber, then assembles conical ring and fastening bolt and axis, tightly spiral shell admittedly
Bolt fits closely the cone path portion of conical ring and axis with the end-beveling on detachable-shaft inner cavity, and conjunction fastening bolt when needs
There is certain pretightning force, rub force request when meeting its dynamic balancing, in order to avoid tooling and detachable-shaft have opposite rotation, influences dynamic flat
The effect of weighing apparatus.
The specifically used process of tool can refer to following example: axis being penetrated and adds chamber in detachable-shaft, then by conical ring and tightly
Fixing bolt and axis assemble, and tightly fixing bolt, keep the cone path portion of conical ring and axis and the end-beveling on detachable-shaft inner cavity close
Fitting, and conjunction fastening bolt when needs certain pretightning force, rub force request when meeting its dynamic balancing, so as not to tooling with can
Tearing axis open has opposite rotation, influences dynamically balanced effect.
Beneficial effects of the present invention:
One end of the present invention is machined with the taper axle journal matched with detachable-shaft internal diameter end chamfer angle, axle journal conical surface surface
It is required that good；There is raised major diameter in the axis other side, convex portion uniform thread mill drilling on certain pitch circle is used for and fastening spiral shell
3, bolt attach together with conical ring 2；Raised outside processes the transition shaft shoulder, with 2 slide fit of conical ring.Conical ring 2 is assembled on the transition shaft shoulder of axis 1,
Keep conical ring 2 free to slide along the transition shaft shoulder on axis 1, processes through-hole on the pitch circle identical as the raised major diameter of axis 1 of conical ring 2, use
In across fastening bolt 3.Fastening dress bolt 3 is standard bolt, and after conical ring 2 is assembled to the transition shaft shoulder on axis 1, fastening is filled
The threaded hole that bolt 3 passes through on unthreaded hole and 1 boss of axis on conical ring 2 screws to realize the purpose of fastening workpiece.
The dynamically balanced precision of detachable-shaft is effectively guaranteed in the present invention, meets the design requirement of drawing and the essence of actual use
Degree, ensure that the practical performance of detachable-shaft, improves the yield rate of workpiece and reduce workload and job costs.It is of the present invention because
For detachable-shaft without, directly the structure of conjunction, transition structure takes clamping mode with dynamic balancing machine, this mode can make detachable-shaft and dynamic flat
Weighing apparatus machine automatic centering avoids the occurrence of the situation generation tested into middle bias.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Fig. 2 is partial structurtes enlarged drawing of the invention.
Specific embodiment
As shown in Figure 1, a kind of large-size machine detachable-shaft dynamic balancing tooling device, by axis 1, conical ring 2 and 3 groups of fastening bolt
