Optionally, ball screw slot is set to one end of shaft, and ball spline slot is set to the other end of shaft.
Optionally, ball screw slot and ball spline slot are arranged in a mutually vertical manner in shaft.
Optionally, shaft radially in set one for air circulation through-hole.
Optionally, through hole section shape is circle；Alternatively, the through hole section shape is rectangle；Alternatively, the through-hole is cut
Face shape is diamond shape.
The utility model has the advantages that due to the adoption of the above technical scheme, the utility model is compact-sized, the device space can be saved.
It should be understood that the above general description and the following detailed description are merely exemplary, this can not be limited
Utility model.
Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets the utility model
Embodiment, and be used to explain the principles of the present invention together with specification.
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, the reference numerals are as follows:
1, shaft；2, ball screw nut；3, ball spline nuts；
4, ball screw slot；5, ball spline slot.
Specific embodiment
It will explain the exemplary embodiments in detail below, the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the utility model.On the contrary, they be only with such as
The example of some aspects be described in detail in the appended claims, the utility model consistent component and method.Root below
The utility model is described in further detail according to drawings and examples.
The ball screw spline structure is illustrated below with reference to Fig. 1.
A kind of ball screw spline structure, including ball screw spline ontology, in which: ball screw spline ontology includes turning
Axis 1.In the present embodiment, shaft 1 radially in set one for air circulation through-hole.In specific implementation, through-hole is cut
Face shape is circle；Alternatively, the through hole section shape is rectangle；Alternatively, the through hole section shape is diamond shape.In the application
In, since through-hole only need to not do its shape for air circulation and further limit.
Optionally, multiple ball screw slots 4 are offered along its axial direction in shaft 1, radially offers ball in shaft 1
Spline 5.
In one possible implementation, ball screw slot 4 is set to one end of shaft 1, and ball spline slot 5 is set to
The other end of shaft 1, i.e. ball screw slot 4 and ball spline slot 5 are respectively arranged in shaft 1.In actual use, the separation
Type ball screw spline structure is suitable for the equipment such as chip mounter.
In alternatively possible implementation, ball screw slot 4 and ball spline slot 5 are arranged in a mutually vertical manner in shaft 1
On, i.e. ball screw slot 4 and ball spline slot 5 is overlapped in shaft 1.In actual use, the Overlapping ball screw
Spline structure is suitable on robot assembly, and furthermore, which is suitable for small-sized
On Scalar robot front end parts.
A ball screw nut 2 is arranged in one end of shaft 1, and a ball spline nuts 3 are arranged in the other end of shaft 1, more into
It says to one step, ball screw nut 2 is sheathed on ball screw slot 4, and ball spline nuts 3 are sheathed on ball spline slot 5.?
In specific implementation, ball screw nut 2 and ball spline nuts 3 and shaft 1 use transition fit；Alternatively, ball screw
Nut or ball spline nuts and shaft use transition fit.
Optionally, 5 quantity of ball spline slot is at least two, and 5 uniform amount of ball spline slot is distributed in shaft 1.
In specific implementation, ball screw nut 2 can be connected to the motor, band of the ball screw nut 2 in motor
Axial-rotation movement is done under dynamic, at this point, ball spline nuts 3 are used as spline structure, and is done under the drive of shaft 1 traversing reciprocal
Movement；Alternatively, ball spline nuts 3 can be connected to the motor, it is dynamic that ball spline nuts 3 do axial-rotation driven by the motor
Make, at this point, torque is transferred in shaft 1 by ball spline nuts 3, so that shaft 1 be driven to do axial-rotation movement.
It should be added that unless otherwise defined, the technical term or scientific term used herein should be this
The ordinary meaning that personage in utility model fields with general technical ability is understood.The utility model patent application specification
And " connection " used in claims either the similar word such as " connected " be not limited to it is physics or mechanical
Connection, but may include electrical connection, it is either direct or indirect."upper", "lower" etc. are only used for indicating opposite
