Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
Referring to Fig.1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of molding integrated on-line dynamic balancing terminal structures of 3D, integration
On-line dynamic balancing terminal bottom offers central bellmouth 3, and integrated on-line dynamic balancing terminal is socketed in by central bellmouth 3
On main shaft 13；Integrated on-line dynamic balancing terminal inner is distributed along the circumference with the identical balance vessel 7 of four shapes, balance
It is separated by chamber wall 6 between vessel 7, prevents the liquid being injected into balance vessel 7 from mutually flowing；Integrated on-line dynamic balancing is whole
The inner circle end face 10 at end is in axial direction designed with four equidistant intake chutes 5, four intake chutes 5 and corresponding balance vessel 7
It is connected to by trapezoidal hole 8, the liquid that the external world is injected on intake chute 5 can flow into corresponding balance vessel 7 by trapezoidal hole 8
In；1 surface of cooperation table top of integrated on-line dynamic balancing terminal inner is the same as being evenly equipped with eight countersunk head threaded holes on Radius circumference
2, countersunk head threaded hole 2 is used for the offline dynamic balancing of balanced termination, is offset by adding screw in corresponding countersunk head threaded hole 2
Initial unbalance, existing for balanced termination.
The integrated on-line dynamic balancing terminal uses 3D rapid shaping technique one-pass moldings, and to there is required precision
Position is machined out；In 3D rapid shapings, using the rear end face 11 of integrated on-line dynamic balancing terminal lower curtate as substrate, with
Play the supporting role to subsequent forming structure；Bellmouth 3 is designed with allowance, and match grinding is advised by cone to improve cone after molding
The machining accuracy in shape hole 3 is more advantageous to the cooperation with 13 tapering of main shaft；The circle end face 9 of integrated on-line dynamic balancing terminal is set
In respect of allowance, after shaping, the finish on surface is improved using mach method, it is right to improve circle end face 9
Photoelectric sensor 12 emits the reflectivity of light, preferably to achieve the purpose that phase demodulation；5 projected depth of intake chute is less than reality
Depth, after shaping, by mach mode by the depth down of intake chute 5, to ensure that the processing matter of intake chute 5
Amount；Front end face 4, rear end face 11, inner circle end face 10 and the cooperation table top 1 of integrated on-line dynamic balancing terminal are in no special precision
In the case of it is required that, it need not be machined out.
