Property.
The embodiment of the present invention provides a kind of relative length regulating device for feedback wire rope track, by turning length difference
It is changed to rotation angle, is actively adjusted so that inside and outside track relative length is able to carry out, guarantees clearance constant between track, thus
Improve the precision of feedback.
Fig. 1 is the structural schematic diagram of relative length length adjustment mechanism provided in an embodiment of the present invention, and Fig. 2 is of the invention real
The structural schematic diagram of the feedback wire rope track of example offer is provided.As depicted in figs. 1 and 2, feedback wire rope track includes inner orbit 8, with
And the first outside track 6 and the second outside track 7 of 8 two sides of inner orbit are set, relative length regulating device includes cooperating to make
First sleeve 1, the second casing 2, the first driving part 5 and the second driving part 9.
Wherein, first sleeve 1 is rotatable is sheathed on feedback wire rope track, and the second casing 2 is rotatable to be sheathed on
On sleeve 1, due to the effect of first sleeve 1 and the second casing 2, it will lead to inner orbit 8 in bending, will drive the first outer rail
Road 6 and the second outside track 7 also move therewith, to can generate between inner orbit 8, the first outside track 6 and the second outside track 7
Length difference.It is understood that due to inner orbit 8, the first outside track 6 and the second outside track 7 be it is flat, this is anti-
Rope tracks are presented only towards 6 side of the first outside track, or the second outside track curving of direction.
To compensate the length difference, the displacement of feedback wire rope in the axial direction can be converted to the angular displacement of rotation, specifically
Ground, the first driving part 6 is connect with the first outside track 6, for driving first sleeve 1 to be rotated in a first direction, and for driving
Dynamic second casing 2 rotates in a second direction；Second driving part 9 is connect with the second outside track 7, for driving 1 edge of first sleeve
Second direction rotation, and for driving the second casing 2 to be rotated in a first direction.
Wherein, first direction and second direction is contrary, for example, first direction be it is clockwise, second direction is inverse
Clockwise；In another example first direction is that counterclockwise, then second direction is clockwise.
, it is understood that since the first driving part 5 is connect with the first outside track 6, outside the second driving part 9 and second
Track 9 connect, and the direction of rotation of first sleeve 1 and the second casing 2 on the contrary, so as to by the first outside track 6 along internal rail
The elongation of road 8 or the displacement variable shunk are converted to the angular displacement of a rotation, and in contrast, the second outside track 7 is along interior
Flexible and the first outside track 6 of track 8 on the contrary, when its displacement variable is converted to the angular displacement of rotation, the angle of rotation with
The angular dimension equal direction that rotates after the conversion of first outside track 6, can by first sleeve 1 and the second casing 2 on the contrary, therefore
Length difference between the inside and outside track of Compensation Feedback rope tracks.
In some alternative embodiments, two group of first scroll wire casing group is offered in first sleeve 1, includes in every group
Two the first scroll wire casings, the hand of spiral of two the first scroll wire casings is on the contrary, and edge in the first scroll wire casing group
The radial direction distance maximum distribution of first sleeve 1 offers and the first spiral shell on the surface of first sleeve 1 on second casing 2
The corresponding second scroll wire casing group of linear wire casing group, the spiral of two the second scroll wire casings in the second scroll wire casing group
It is contrary, and along 2 radial direction of the second casing distance maximum distribution on the outer surface of the second casing 2.Wherein, the first spiral shell
Linear wire casing group is opposite with the second scroll wire casing group hand of spiral.
Preferably, the first driving part 5 is two guide posts, and two guide posts are connect with the first outside track 6, and are set respectively
It is placed in the first scroll wire casing and the second scroll wire casing of 6 side of the first outside track；Second driving part 9 is also two
A guide post is connect with the second outside track 7, and be respectively arranged at positioned at 7 side of the second outside track the first scroll wire casing and
In second scroll wire casing, the guide post and the second outside track 7 on the first outside track 6 will lead to due to feedback wire rope curved in tracks
On guide post between relative position change so that guide post is in the first scroll wire casing and the second scroll line
It is moved in slot, guide post is connect with the first outside track 6 or the second outside track 7, and then can drive first sleeve 1 and the second casing
2 make the length difference that contrary rotary motion is generated with the bending of Compensation Feedback rope tracks.
It should be noted that the first driving part 5 and the second driving part 6 are not limited to guide post, it can also be other
Structure, for example, bolt, in another example, fixed sliding block, as long as can guarantee that it can be moved in scroll wire casing.
In some alternative embodiments, the length of the first scroll wire casing and the second scroll wire casing and feedback steel mould rail
Meet following relationship between the extending direction compensation rate in road:
R=x*cos θ,
In formula, x is feedback wire rope track extending direction compensation rate, and R is the length of scroll wire casing, and θ is scroll wire casing
Angle.
In some alternative embodiments, relative length regulating device further includes the first sliding block 3, the second sliding block 4, to make
First outside track 6, the second outside track 7 are smooth relative to the opposite sliding of inner orbit 8, and the first sliding block 3 is set to the first outside track 6
Between inner orbit 8, the second sliding block 4 is set between the second outside track 7 and inner orbit 8.
In the embodiment of the present invention, pass through first sleeve 1, the second casing 2, the first driving part 5 and the second driving part 9
It can not only the length difference that generates of Compensation Feedback rope tracks bending, additionally it is possible to so that feedback wire rope track is during bending,
Gap between first outside track 6, the second outside track 7 and inner orbit 8 does not change, to efficiently avoid due to this
Feedback signal inaccuracy caused by the change in gap.
On the other hand, the present invention also provides a kind of feedback wire rope track, which includes above-mentioned opposite
Length adjustment device, compared with the prior art in feedback wire rope track, feedback wire rope track provided by the invention can guarantee
Gap is certain between inside and outside track, and carries out active control to length difference, and number of parts is few, simple and compact for structure, size
It is small, precision is high.
Finally it is noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, those skilled in the art should understand that: it is still
It is possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes；And these are modified or replaceed, the essence for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution
Mind and range.
