Description
Technical field
A kind of linkage part is the utility model is related to, is specially a kind of suitable for low load, the automatic butt of low torque
Spline joint.
Background technology
Spline joint is widely used in field of automatic testing, it is many it is performance test bed on usually lean on spline and spline
Connector is to fetching transmission moment of torsion.At present, in general spline joint has two kinds of technical solutions, and one kind is spline joint after docking
Locking is, it is necessary to the locking device of complexity, and the manufacture of this scheme is complicated, ending volume is larger, takes larger space, and the scope of application is small,
The device docking operation has holding process, and docking time length, docks inefficiency；Another kind is designed using easy connector,
But it is correctly docking, the design of spline joint part, the tolerance of manufacture of docking are small, and the accuracy of manufacture requires height, have docking effect
Rate is high, and butt end is small, applied widely, but with using process abrasion, greatly, service life is short, and docking operation has impact etc.
Shortcoming.
Utility model content
For in the prior art the defects of, the utility model provides a kind of spline joint of automatic butt, its is simple in structure,
Cost is low, docking impact is small, docking is efficient.
Technical solutions of the utility model are as follows：
A kind of spline joint of automatic butt, its key are：Drive division and docking section including integrally connected successively；Institute
The structure that is square outside drive division is stated, inside is in hollow cylindrical, and the drive division is connected with driving mechanism；The docking section
Cylindrical structure, offers several long narrow straight slots, the straight slot is circumferential etc. along docking section along the docking section is circumferentially parallel
Spacing is distributed；The drive division and docking section center line are located on the same line.
Drive division described in the utility model is connected with driving mechanism, when needing to dock with spline, adjusts spline joint
Axis is located on the same line with spline axis, and driving mechanism drives spline joint close to spline, in the process, driving machine
Structure drives spline joint low speed rotation at the same time.If spline joint is directly docked with spline, without waste motion；If spline joint
Do not docked directly with spline, since spline joint docking section is uniformly provided with a plurality of long narrow straight slot, spline joint goes out with spline
Now opposite to slide, spline joint produces elastic deformation, and spline joint is stretched, after opposite slip, spline and spline joint pair
Socket part engages, and after the completion of engagement, spline joint elastic deformation is restored, and is docked successfully.
Compared with conventional spline connector, the utility model is simple in structure, and docking time is shorter, and cost is lower；Using above-mentioned
Structure, spline joint can produce elastic deformation in docking operation, using elastic deformation apparatus with shock absorbing, compared to traditional flower
Bonded head, the utility model impacts smaller in docking operation, not easy to wear, has the advantages that service life is long.In addition, this reality
The automatic butt of spline and spline joint is realized with new, while has the advantages that docking is efficient.
Further, the docking section inner wall of end is equipped with chamfering structure.In spline and spline joint docking operation, flower
The bonded nearly spline of head rest, the chamfering structure play the guiding role.
Further, the end of the straight slot offers the circular hole that diameter is more than the straight slot width.
Further, the drive division and docking section be by a changeover portion integrally connected, and the changeover portion is to spline joint
Centerline direction indent.
Further, the spline joint uses spring steel material.Spring steel material elastic deformation function admirable.
Brief description of the drawings
, below will be right in order to illustrate more clearly of the utility model embodiment or technical solution of the prior art
Embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In all of the figs, it is similar
Element or part are generally identified by similar reference numeral.In attached drawing, each element or part might not be according to actual ratios
Draw.

Fig. 2 is the schematic perspective view of the utility model spline joint；
Fig. 3 is the simplified diagram that spline is docked with spline joint；
In attached drawing：1- drive divisions；2- docking sections；21- straight slots；22- circular holes；23- chamfering structures；3- changeover portions；4- splines.
Embodiment
The embodiment of the utility model is described in further detail below in conjunction with the accompanying drawings.
In the present embodiment, the orientation or position of the instruction such as term " on " " under " " left side " " right side " " preceding " " rear " " upper end " " lower end "
It is based on orientation shown in the drawings or position relationship to put relation, is for only for ease of description, rather than indicates or imply meaning
Device or element must have specific orientation, with specific azimuth configuration or operation, therefore it is not intended that new to this practicality
The limitation of type.
As shown in Figure 1 to Figure 3, a kind of spline joint of automatic butt, including the drive division 1 of integrally connected and docking successively
Portion 2, be square outside the drive division 1 structure, and inside is in hollow cylindrical, and the drive division 1 is connected with driving mechanism；Institute
2 cylindrical structure of docking section is stated, several long narrow straight slots 21, the straight slot 21 are offered along the docking section 2 is circumferentially parallel
Along the circumferential equidistantly distributed in docking section 2；The drive division 1 and 2 center line of docking section are located on the same line.It is and described right
Socket part inner wall of end is equipped with chamfering structure 23.
Drive division 1 described in the utility model is connected with driving mechanism, and when needing to dock with spline 4, adjustment spline connects
Head axis is located on the same line with 4 axis of spline, and driving mechanism drives spline joint in the process, to be driven close to spline 4
Motivation structure drives spline joint low speed rotation at the same time.Spline joint falls close to spline 4,2 inner wall of end of spline joint docking section
Corner structure 23 has guiding role.If spline joint is directly docked with spline, without waste motion；If spline joint and spline
Do not dock directly, since spline joint docking section 2 is uniformly provided with a plurality of long narrow straight slot 21, spline joint phase occurs with spline
To sliding, the docking section 2 of spline joint produces elastic deformation, and spline joint docking section 2 is stretched, after opposite slip, spline
Engaged with spline joint docking section 2, after the completion of engagement, spline joint elastic deformation is restored, and is docked successfully.
Compared with conventional spline connector, the utility model is simple in structure, and docking time is shorter, and cost is lower；Using above-mentioned
Structure, the docking section 2 of spline joint can produce elastic deformation in docking operation, pass through elastic deformation apparatus with shock absorbing, phase
Than traditional spline joint, the utility model impacts smaller in docking operation, not easy to wear, has the excellent of service life length
Point.In addition, the utility model realizes the automatic butt of spline 4 and spline joint, while have the advantages that docking is efficient.
As shown in Figure 1, the end of the straight slot 21 offers the circular hole 22 that diameter is more than the straight slot width.The driving
Portion 1 and docking section 2 are by 3 integrally connected of a changeover portion, and the changeover portion 3 is to spline joint centerline direction indent.The flower
Bonded head uses spring steel material.
The utility model is suitable for low load, low torque equipment.In practical application, according to the Parameter of spline of docking, use
Suitable design；Its main being achieved in that uses suitable manufacture material, and uses appropriate parameter designing, by circle
