Abstract
The invention discloses a medical dental CT (Computed Tomography) formal prototype directly driven by a direct drive motor. The medical dental CT formal prototype mainly comprises a fixed support frame (12), a rotating bracket (1) as well as an X-ray machine (16) and a detector (17), which are respectively arranged at two ends of the rotating bracket. A slip ring (2) which is used for electric and optical fiber connection is arranged near a central shaft of a motor; the rotating bracket (1) is fixedly connected to a motor rotor (7) outside the slip ring through a load mounting plate (5); and a motor stator (8) is connected with the fixed support frame (12). The medical dental CT formal prototype has the characteristics of high rotation precision and positioning accuracy as no intermediate transmission mechanism is arranged; no rotating arm is needed to return by reverse rotation; and in addition, and the connection of cables is not influenced, thus the space can be conveniently reduced. The rotating bracket can be rotated in an unlimited angle manner, and convenience is provided for operation and use.
Description
Affiliated technical field
The present invention relates to dental therapeutic apparatus, relate in particular to a kind of positive model machine technical field of medical-dental CT that adopts direct driving motor directly to drive.
Background technology
The positive model machine of dentistry CBCT is one of key equipment of dental disorder diagnosis, to be x-ray generator do annular digital throwing photograph with lower quantity of X-rays X around oromaxillo-facial region rotation sweep 180-360 degree to its principle, then will around throw according to body repeatedly numeral throw recombinate in computer according to the data that obtained in the back " commons factor " after so that the acquisition 3-D view.The frame for movement of the positive model machine of CT drives the runing rest rotation by driving arrangement as shown in Figure 1, and the numeral that makes different angles gather oromaxillo-facial region is thrown photograph, and the runing rest Spin Control is needed higher precision.The positive model machine of traditional dentistry CT adopts intermediary agency's transmission, be to have intermediary power transmission chain between drive motors and the turning arm 1, drive mechanisms such as reductor, belt transmission, worm and gear need be set, positioning accuracy is poor, increase mechanical clearance, influence the synchronicity of acquired signal, increase driving error, easily cause mechanical shaking, and infinitely angle is rotated, and has influenced the image quality of X ray.
Summary of the invention
Above shortcoming in view of prior art, the objective of the invention is, the positive model machine rotation of a kind of dentistry CT that adopts direct driving motor directly to drive sample devices is provided, make it to have and adopt direct driving motor directly to drive, no intermediate transmission mechanism, can realize the unlimited angle rotation of runing rest, running accuracy height, the characteristics of accurate positioning.
The objective of the invention is to realize by following means.
A kind of positive model machine of medical-dental CT that adopts direct driving motor directly to drive is mainly by fixing support rack 12, runing rest 1 and divide the radiography unit 16 and the detector 17 that are located at the runing rest two ends to form.Be provided with near the motor center axle and be used for the electric slip ring that is connected with optical fiber 2; Runing rest 1 is fixedly connected on the rotor 7 that places outside the slip ring through overload installing plate 5; Motor stator 8 is connected with fixing support rack 12.
Adopt structure of the present invention, no intermediate transmission mechanism has the running accuracy height, and the characteristics of accurate positioning do not need turning arm counter-rotating playback, and do not influence the connectivity problem of cable, help dwindling the space.Can realize the unlimited angle rotation of runing rest, handled easily uses.
Description of drawings:
Fig. 1 is positive model machine main body outside drawing.
The A-A profile of Fig. 2 Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and concrete enforcement the present invention is further described.
Have shown in Figure 1,1-runing rest, 12-fixing support rack, 15-patient's seat, 16-radiography unit, 17-detector.
As seen from Figure 2, the present invention adopts runing rest that direct driving motor directly drives the positive model machine of CT to be applicable to the detection of any angle, and concrete frame mode is as follows: direct driving motor stator 8 adopts bolts 9 and bolt 11 to be fastened on the fixing support rack 12 of the positive model machine of dentistry CT through turntable mount pads 10.Direct drive motor rotor 7 can be rotated around direct driving motor stator 8 central shafts by the electromagnetic torque driving.Runing rest 1 adopts bolt 4 to fixedly connected with bolt 6 through overload installing plate 5.Slip ring 2 is installed on the runing rest 1 and is connected with load installing plate 5 by pin 3.When direct drive motor rotor 7 rotations, drive load installing plate 5, runing rest 1 and slip ring 2 rotations.Slip ring 2 is connected to be applicable to unlimited angle rotation in order to the electric and optical fiber of rotational structure.
