Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 ~ Fig. 3 schematically shows the structure of the unit clamp of the calibration optical electric axial angle encoder of a kind of embodiment of the utility model.
As shown in Figures 1 to 3, a kind of unit clamp calibrating optical electric axial angle encoder, mainly comprise pedestal 1, to be arranged in rotating shaft on pedestal 12 (preferred, the left and right sides of pedestal 1 is fixed with bearing 21, rotating shaft 2 is arranged on bearing 21), the left end of rotating shaft 2 and right-hand member all stretch out pedestal 1, and the left side of pedestal 1 is provided with substrate 3, and substrate 3 is provided with the through hole 31 with rotating shaft 2 coaxial cable.The polygon 71 of outside can be fixed on the right-hand member of rotating shaft 2, the rotating shaft of the scrambler 8 of the left end of rotating shaft 2 and outside can be fixed together by positive coupling, meanwhile, the housing of scrambler 8 is fixed on substrate 3, so just can realize the purpose of this utility model.
The purpose of this utility model is in order to the rotating shaft of the scrambler 8 by outside is coaxially connected with polygon 71.Utility model can be calibrated accurately to scrambler 8.
As shown in Figure 1, pedestal 1 is fixed on base plate 4, and the lower end of substrate 3 is connected with base plate 4 is removable by slide rail 5.In the present embodiment, the optimal way of removable connection is: on base plate 4, be fixed with slide rail 5, match with slide rail 5 in the lower end of substrate 3, therefore, substrate 3 can move left and right along slide rail 5, when substrate 3 moves certain distance, by dog screw 51, substrate 3 can be fixed on slide rail 5, prevent substrate 3 again from line slip.In other embodiments, the mode of removable connection also can be: base plate 4 forms continuous print draw-in groove, and the lower end of substrate 3 snaps in draw-in groove, and this kind of situation also can become the removable connection of class (be in the nature and removably connect).Because substrate 3 is connected for removable with base plate 4, when being fixed on the substrate 3 by the shell of scrambler 8, by the position of moving substrate 3, positive coupling is more easy to be coupled together the axle of scrambler 8 and rotating shaft 2.
As shown in Figure 1, three equally distributed strip through holes 32 are provided with around the through hole 31 of substrate 3, strip through hole 32 can make outside scrambler 8 be fixed on the left surface of substrate 3, as: the right flank of scrambler 8 forms dog screw, dog screw is passed strip through hole 32 and tightens, certainly, the rotating shaft of scrambler 8 is not fixed.
As shown in Figures 1 to 3, pedestal 1 forms tapped through hole, degree of tightness pin 11 and tapped through hole removably connect, and the lower end of degree of tightness pin 11 is screwed in pedestal 1.Degree of tightness pin 11 can change the friction force be subject to when rotating shaft 2 is rotated, and that is to say: when one end of degree of tightness pin 11 props up rotating shaft 2, and the friction force be subject to is rotated in rotating shaft 2 to be increased; When degree of tightness pin 11 leaves rotating shaft 2, rotating shaft 2 is rotated the friction force be subject to and is reduced.The object of increase degree of tightness pin 11 is the rotating speeds in order to control when rotating shaft 2 is rotated, and prevents rotating shaft 2 from rotating too fast and cannot realize exact localization operation.
As shown in Figures 1 to 3, pedestal 1 and rotating shaft 2 contact position are fixed with locating ring 22, and rotating shaft 2 forms projection with the contact position of locating ring 22, and locating ring 22 blocks rotating shaft 2 by projection, prevents rotating shaft 2 from operationally moving left and right and affecting measurement result.
As shown in Figure 1, to be threaded dead ring 23 at rotating shaft 2 right-hand member, when the polygon 71 of outside is put in the right-hand member of rotating shaft 2, dead ring 23 can to have been screwed in, polygon is fixed on rotating shaft shaft shoulder side by dead ring 23, is convenient to polygon and keeps stablizing and being in plumbness.
In the present embodiment, the xsect of pedestal 1 is cuboid, and pedestal 1 is embedded in base plate, and four angles of base plate are equipped with feet 6.The existence of feet 6 conveniently can use novel use.In other embodiments, the xsect of pedestal 1 also can be circle etc.
Use procedure of the present utility model is as follows:
As shown in Figure 3, be first fixed in back up pad 5 by scrambler 8 right flank by the strip through hole 32 being mutually 120 °, the rotating shaft 2 in the turning axle of scrambler 8 and pedestal is connected and fixed by the positive coupling in the recycling external world.The right-hand member of rotating shaft 2 installs polygon 71, and utilizes dead ring 23 to fixedly positioning.Holding dead ring 23 drives rotating shaft 2 to rotate, and by the contact of adjusting elasticity pin 8 with rotating shaft 2, rotating shaft 2 is in the controlled range of speeds of staff, so that the positioning action of polygon 71 rotational angle.Staff drive shaft 2 is rotated, and can realize the coaxial rotation of polygon 71 and scrambler 8.The rotational angle of polygon 71 is accurately determined (prior art) by autocollimator 7, then can be calibrated encoder angular measurement error by the angle comparing the anglec of rotation that the reading device that is connected with scrambler 8 shows and polygon 71 actual rotation.
The turning axle of scrambler 8 can coaxially be connected with polygon 71 by the utility model, thus realizes calibrating accurately encoder angular measurement error.
Above is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
