Abstract
The invention relates to the technical field of photoelectric measurement, and specifically to a spindle system. The spindle system comprises a motor, a base and a spindle arranged on the base, wherein a measuring device is arranged at the end part of one end of the spindle while a dividing head is arranged at the end part of the other end of the spindle; the spindle is arranged on the base through a holding frame; and multiple rolling balls are arranged between the spindle and the holding frame. The spindle system reduces 0.5 times eccentric error of the spindle, can position a cutter on a cutter head exactly, enables the cutter to be adjusted conveniently, reduce friction between the spindle and the holding frame, prolongs the service life of the spindle efficiently and reduces repeated error of the spindle system. In addition, the spindle system also has the advantages of a light weight and a great supporting capacity.
Description
Technical field
The present invention relates to the photoelectric measurement technical field, specifically is a kind of axis system.
Background technology
Gear is the mechanical organ that the continuous engaged transmission motion of tooth energy and power are arranged on a kind of wheel rim, in the process of gear, several cutters need be fixed on the cutterhead, after cutterhead is adjusted the tool position, flitch is processed into gear, especially, use in the process of gear at automobile, required precision to gear is very high, and automobile need be fixed on cutterhead on the main shaft with Gear Processing usually and rotary main shaft is measured the position of cutter, and there is eccentric error when rotated in main shaft, and along with equipment constantly uses, eccentric error also can constantly increase, there is the shortcoming of poor repeatability in axis system, and it is relatively poor to adjust the fix a cutting tool accuracy of gear that processes behind the position of cutterhead.
Summary of the invention
At above-mentioned weak point of the prior art, the present invention aims to provide the axis system that a kind of repeatability is better, certainty of measurement is higher.
For solving the problems of the technologies described above, axis system of the present invention, it comprises motor, pedestal and is arranged at main shaft on the described pedestal, this main shaft one end end is provided with measurement mechanism, main shaft other end end is provided with dividing head, main shaft is arranged on the pedestal by retainer, is provided with several balls between main shaft and the retainer.
Concrete, described measurement mechanism comprises fixed disc, circle grating, is arranged at locational two read heads of fixed disc diameter, and the circle grating is arranged at the spindle nose outside.
Described round grating is the ring-type stainless steel structure.
Described retainer comprises first retainer that arranges near dividing head and second retainer that arranges near measurement mechanism.
Ball diameter between described first retainer and the main shaft is greater than the ball diameter between second retainer and the main shaft.
Described motor is direct driving motor.
Described alignment of shafts position has a column type cavity.
Axis system of the present invention, because main shaft one end end is provided with measurement mechanism, main shaft other end end is provided with dividing head, measurement mechanism is used for measuring the eccentric error that produces when main shaft turns an angle, if the data that a read head in the measurement mechanism is measured are A, the data that another read head is read are B, and measurement result is represented with C, C=(A+B so)/2, can reduce the eccentric error of 0.5 times of axis system; Dividing head is used for fixation cutter head, not only can accurately locate the cutter on the cutterhead, and convenient the adjusting; Be provided with several balls between main shaft and the retainer and not only reduce friction between main shaft and the retainer, effectively prolonged the service life of main shaft, and reduced the repeatability error of axis system, the present invention also has the advantage that quality is light, supporting power is big in addition.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the cross-sectional view of axis system of the present invention;
Fig. 2 is the perspective view of axis system measurement mechanism face of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figures 1 and 2, axis system of the present invention, it can comprise motor 1, pedestal 2 and be arranged at main shaft 3 on the described pedestal 2, these main shaft 3 one end ends are provided with measurement mechanism, main shaft 3 other end ends are provided with dividing head 4, main shaft 3 is arranged on the pedestal 2 by retainer, is provided with several balls between main shaft 1 and the retainer.Axis system of the present invention is because main shaft 3 one end ends are provided with measurement mechanism, main shaft 3 other end ends are provided with dividing head 4, measurement mechanism is used for measuring the eccentric error that produces when main shaft 3 turns an angle, dividing head 4 is used for fixation cutter head, not only can accurately locate the cutter on the cutterhead, and convenient the adjusting; Be provided with several balls between main shaft 3 and the retainer and not only reduce friction between main shaft 3 and the retainer, effectively prolonged the service life of main shaft 3, and reduced the repeatability error of axis system.
Concrete, described measurement mechanism comprises fixed disc 5, circle grating 6, is arranged at locational two read heads 7 of fixed disc 5 diameters, and circle grating 6 is arranged at the outside, main shaft 3 ends.If the data that a read head in the measurement mechanism is measured are A, the data that another read head is read are B, and measurement result represents with C, so C=(A+B)/2, the eccentric error of 0.5 times of axis system can have been reduced.
Described round grating 6 is the ring-type stainless steel structure.
Described retainer comprises first retainer 8 that arranges near dividing head 4 and second retainer 9 that arranges near measurement mechanism.First retainer 8 and second retainer 9 have guaranteed that effectively main shaft 3 is more stable.
Ball diameter between described first retainer 8 and the main shaft 3 is greater than the ball diameter between second retainer 9 and the main shaft 3.Not only reduce the friction between main shaft 3 and the retainer, effectively prolonged the service life of main shaft 3, and it is more stable that main shaft 3 is rotated.
Described motor 1 is direct driving motor.Avoid using drive apparatus such as driving belt, can increase the system failure because these equipment use, so adopt direct driving motor to effectively reduce fault rate.
Described main shaft 3 centers have a column type cavity 10.Reduce the quality of system, reduced the use of material, reduced production cost.
The present invention is when concrete the use, starter motor 1, motor 1 drives main shaft 3 rotations, main shaft 3 drives 6 rotations of circle grating, circle grating 6 is read two data during by two read heads, transfer of data to computer system (not shown) is carried out data handle and draw deviation data, on the dividing head 4 behind the fixation cutter head, this deviation data as the reference data of adjusting the tool position, has been guaranteed that effectively axis system has higher precision.
