Abstract
The present invention relates to a kind of spindle motor rotor self-locking type assembles device, including main shaft, sleeve, rotor, the face of cylinder and thread segment composition.Rotor interference is installed on sleeve；Sleeve includes front end smooth, cylindrical peripheral surface cooperation with main shaft coupling part and rear end screw thread taper seat is connected, the guide-localization function of motor and main shaft is realized on the face of cylinder, guarantee that main shaft, sleeve and spindle motor are coaxial, rational taper seat thread rotary orientation design can ensure that and produces self-locking between rotor and main shaft in rotary course.Adopt between sleeve and main shaft and threaded it is easy to motor and the lossless assembly and disassembly of main shaft, reduce manufacture and maintenance cost.
Description
Technical field
The present invention relates to a kind of electric spindle motor rotor and the assembly connection technology of main shaft, belong to mechanical design field.
Background technology
Machine tool chief axis are combined together by electro spindle with motor, are widely used in high-speed precise machine tool field.Electro spindle by
Built-in motor direct drive is it is achieved that the Zero-drive Chain of main shaft.Due to needing high-speed rotation or transmitting large torque and adjoint
Often dismantle, rotor is received much concern with mounting technology with the connection of main shaft, the method commonly used at present includes：1. it is press-fitted method：
Rotor is adopted on pressure force fit spindle rotor fitting surface；2. cementing method：Rotor is combined with spindle rotor
Face applies gluing, and hot setting is assembled；3. hydraulic sleeve method：Using hydraulic sleeve, rotor is connected with main shaft interference, dismounting
Hydraulic oil is injected, sliding is unloaded vertically by rotor using pressure differential in Shi Zaixiang hydraulic sleeve.It is to be appreciated that above several classes
The problem that assembling mode is brought is that dismounting is difficult, easily causes the damage of spindle motor rotor in unloading process simultaneously.
Content of the invention
Technical problem：Commonly use the problem that assembly connection method exists for spindle motor rotor, the invention provides a kind of
Spindle motor rotor self-locking type assembling device is it is intended to obtain that a class formation is simple, convenient disassembly, transmitting torque are reliably new
Spindle motor assembly method.
Content of the invention：For solving above-mentioned technical problem, the invention provides this device includes main shaft, located at the outerface of spindle
And the sleeve coaxial with main shaft, located at the rotor of cartridge exterior, the left end of main shaft is the face of cylinder, and right-hand member is provided with thread segment；Wherein,
Main shaft adopts smooth, cylindrical peripheral surface to guide with the front end of hub internal bore, and rear end is connected by thread segment；
It is threaded connection between sleeve and main shaft and realize self-locking.
Preferably, sleeve adopts face of cylinder guide-localization and thread segment self-locking to be connected with main shaft.
Beneficial effect：
Spindle motor rotor self-locking type of the present invention assembles device, guides positioning section using the face of cylinder, enables motor and turn
Son is accurately positioned with main shaft, keeps the dynamic balance accuracy of rotor；Using threaded section, in cutting (grinding) power and electricity
Under the collective effect of machine driving moment, enable the self-locking of rotor；Threaded it is easily installed, dismantles and safeguards.
Brief description
Fig. 1 is spindle motor rotor self-locking type assembling structure.
In figure：Main shaft；2nd, sleeve；3rd, rotor；4th, the face of cylinder；5th, thread segment
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to patent of the present invention：
The present invention relates to a kind of spindle motor rotor self-locking type assembles device, including main shaft, sleeve, rotor,
The face of cylinder and thread segment composition.Rotor interference is installed on sleeve；Sleeve and main shaft coupling part include the smooth circle in front end
Cylinder cooperation and rear end screw thread taper seat connect, and the guide-localization function of motor and main shaft is realized it is ensured that main shaft, sleeve in the face of cylinder
Coaxial with spindle motor, the design of rational taper seat thread rotary orientation can ensure that between rotor and main shaft in rotary course
Produce self-locking.Adopt between sleeve and main shaft and threaded it is easy to motor and the lossless assembly and disassembly of main shaft, reduce manufacture and tie up
Shield cost.
Referring to Fig. 1, the spindle motor rotor self-locking type assembling device that the present invention provides, this device includes main shaft 1, located at
Main shaft 1 outer surface the sleeve 2 coaxial with main shaft 1, the rotor 3 outside located at sleeve 2, the left end of main shaft 1 is the face of cylinder 4, right
End is provided with thread segment 5；Wherein,
Rotor 3 is connected with sleeve 2 interference；
Main shaft 1 is guided using smooth, cylindrical peripheral surface 4 with the front end of sleeve 2 endoporus, and rear end is connected by thread segment 5；
The thread rotary orientation of sleeve 2 and main shaft 1 with main shaft work direction of rotation reasonable disposition it is ensured that in main shaft rotary course,
It is threaded connection between sleeve 2 and main shaft 1 and realize self-locking.
Sleeve 2 adopts the face of cylinder 4 guide-localization and thread segment 5 self-locking to be connected with main shaft 1.
The above be only the preferred embodiment of the present invention it should be pointed out that：Ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
