Traditional transportation anchor fitting, or be on the chi shell, to beat tapped bore, by tapped bore anchor fitting is fixed on the chi shell, do like this and not only destroyed the chi shell structure but also increased tooling cost and the time; Be exactly that structure is too complicated, increased tooling cost and also be unfavorable for operation.
Summary of the invention
The objective of the invention is when transportation optical grating ruler measurement device, the transportation anchor fitting by a kind of grating chi of the present invention can be fixed on the balladeur train body on the chi shell, when being installed on the lathe, can unclamp this transportation anchor fitting to optical grating ruler measurement mechanism.
The transportation anchor fitting of a kind of grating chi of the present invention comprises matrix, arrange on this matrix and hold out against parts, this holds out against the component upper ends setting and holds out against the dip plane, this dip plane is contacted with chi shell dip plane or break away from by screw, described matrix arranges groove, this groove is corresponding with the guide rail of chi shell, and described matrix arranges circular arc depression, and this circular arc depression matches with arc-shaped convex on the balladeur train body;
Described matrix can vertically move along the guide rail of chi shell;
Described matrix arranges spacer, and this spacer places between chi shell and the balladeur train body;
The described root that holds out against parts arranges circular groove;
Place hexagonal nut in the described matrix, this hexagonal nut and screw fit, the top of this matrix arranges square groove.
The invention has the beneficial effects as follows, the dip plane, upper end that holds out against parts on the transportation anchor fitting matrix by a kind of grating chi cooperates with the dip plane of chi shell makes it captive joint with the chi shell is good, cooperates it is captiveed joint with the balladeur train body is good intact the fixing of chi shell of the balladeur train body of optical grating ruler measurement mechanism and optical grating ruler measurement mechanism in having realized transporting with the arc-shaped convex of balladeur train body by the circular arc on matrix depression.The transportation anchor fitting of a kind of grating chi of the present invention is made simple, easy to operate, has saved tooling cost and time, and is practical.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Optical grating ruler measurement mechanism as depicted in figs. 1 and 2, it comprises the transportation anchor fitting 6 of key light grid chi 1, chi shell 2, indication grating chi 3, scanning mechanism 4, balladeur train body 5 and grating chi.With about the transportation anchor fittings 6 of grating chi of two cover symmetries balladeur train body 5 can be fixed on the assigned position of chi shell 2, after optical grating ruler measurement mechanism is loaded onto lathe, balladeur train body 5 can unclamp the transportation anchor fitting 6 of grating chi, so that can vertically move with scanning mechanism 4 when measuring mechanism moves.The transportation anchor fitting 6 of grating chi and balladeur train body 5 cooperate by circular arc depression 18 and arc-shaped convex 19 and are fixed together.
As shown in Figure 3, have the parts of holding out against 14 on the matrix 7, this holds out against parts 14 upper ends and arranges and to hold out against dip plane 15, this dip plane is contacted with chi shell dip plane 16 or breaks away from by screw 9, has hexagonal nut 8 in the matrix 7, this hexagonal nut 8 cooperates with screw 9, when precession screw 9, hold out against parts 14 and deform at root, when distortion is enough, the dip plane, upper end 15 that holds out against parts 14 contacts with the dip plane 16 of chi shell 2, thereby matrix 7 is fixed on the chi shell 2; When screwing out screw 9, the root that holds out against parts 14 resiles, and the chi shell dip plane 16 that the upper end that holds out against parts 14 holds out against parts dip plane 15 and chi shell 2 disengages, and matrix 7 can slide along chi shell 2.
The guide rail 13 of chi shell 2 is corresponding with the groove 12 of the transportation anchor fitting 6 of grating chi, is easy to the installation location of the transportation anchor fitting 6 of grating chi, also makes things convenient for it directed mobile along guide rail 13.
Also have spacer 17 on the matrix 7 of the transportation anchor fitting 6 of grating chi, this spacer 17 places between chi shell 2 and the balladeur train body 5, and the chi shell 2 that can make optical grating ruler measurement mechanism by this spacer 17 and balladeur train body 5 keep suitable distance.
As shown in Figure 4 and Figure 5, have circular groove 10 at the root that holds out against parts 14, it is thin to make the root that holds out against parts 14 compare with other parts, and its root is easier under the effect of screw 9 deforms, and matrix 7 holds out against to be connected also to make things convenient for to break away from the 2 convenient foundation of chi shell and connects.Have square groove 11 at matrix 7, guarantee the thickness evenness of the transportation anchor fitting 6 of whole grating chi, also make things convenient for the transportation anchor fitting 6 that manually holds out against with the grating chi that slides.The circular arc that has on the matrix 7 of the transportation anchor fitting 6 of grating chi caves in 18, and this circular arc depression 18 cooperates fixing with the arc-shaped convex 19 of balladeur train body 5.
Grating chi transportation anchor fitting 6 in sum, by the special construction that arranges at matrix 7, the upper end that namely holds out against parts 14 holds out against parts dip plane 15 and cooperates with the chi shell dip plane 16 of chi shell 2 it is captiveed joint with the chi shell is good, cooperates it is captiveed joint with the balladeur train body is good intact the fixing of chi shell of the balladeur train body of grating chi and grating chi during the transportation anchor fitting 6 of grating chi of the present invention has been realized transporting with the arc-shaped convex 19 of balladeur train body 5 by the circular arc on matrix depression 18.And this apparatus structure is simple, and is easy to process, and cost is low; Easy to operate, practical.
