Description
Technical field
The present invention relates to the medical X-ray machine part, specifically is a kind of bulb connecting device that improves control accuracy and the X-ray production apparatus beam-defining clipper that increases the service life.
Technical background
The use of prior art X-ray production apparatus beam-defining clipper is that beam-defining clipper is connected on the bulb, guarantees that with this beam-defining clipper axis is consistent with the axis that X-ray production apparatus penetrates ray.In the time of necessary, beam-defining clipper and bulb relatively rotating also is to reach the use needs.
For realizing above-mentioned requirements, be beam-defining clipper to be connected on the bulb at present through connecting device.The connecting device of prior art is referring to accompanying drawing 1; Comprise bulb connecting ring (1); Be fixed on the location gear ring (3) of bulb connecting ring (1) bottom through screw (4); Bulb connecting ring (1) is compressed into connecting ring seat ring (8) through connecting ring pressing plate (7); Connecting ring pressing plate (7) is fixed on connecting ring seat ring (8) upper surface through hold-down screw (6), has the gap between bulb connecting ring (1) and the connecting ring seat ring (8), to guarantee relatively rotating between bulb connecting ring (1) and the connecting ring seat ring (8).During use; Through attachment screw bulb connecting ring (1) is connected with bulb; Through attachment screw connecting ring seat ring (8) is connected with beam-defining clipper; This structure has realized being connected between beam-defining clipper and the bulb, also guaranteed relatively rotating between beam-defining clipper and the bulb simultaneously, and this structure is through realizing along last locating slot in the location gear ring (3); But this structure since the gap exist all the time, cause limiter of speed inevitably occur the pine spacious, rock, thereby reduced control accuracy; Because between bulb connecting ring (1) and the connecting ring seat ring (8) is to be slidingly matched, wearing and tearing can appear after long-time the use, and further make control accuracy reduce; Simultaneously; The metal fillings that wearing and tearing occur is easy to drop inner at beam-defining clipper, makes the pseudo-shadow of imaging to occur, causes the diagnosis mistake; Bring loss for patient and hospital; Hospital is a DE of avoiding bringing because of medical apparatus and instruments the doctor, and the measure of taking usually is exactly regularly firm exchange device, makes use cost than higher.
In sum, the connecting device of prior art beam-defining clipper and bulb in use: control accuracy reduces along with the prolongation of service time, and serious wear makes that service life is short and misleads the diagnosis result.
Summary of the invention
The purpose of this invention is to provide a kind of bulb connecting device that improves control accuracy and the X-ray production apparatus beam-defining clipper that increases the service life.
For realizing that the technical scheme that the object of the invention adopts is: a kind of bulb connecting device of X-ray production apparatus beam-defining clipper comprises that bulb connecting ring, the location gear ring, the bulb connecting ring that are fixed on bulb connecting ring bottom through screw are arranged in the connecting ring seat ring; Wherein: between said bulb connecting ring and the connecting ring seat ring bearing is installed, the outer ring of bearing is pressed on gear ring upper surface, location through the connecting ring pressing plate that is fixed on connecting ring seat ring upper surface.Said connecting ring pressing plate is fixed on connecting ring seat ring upper surface through hold-down screw.Said connecting ring seat ring upper surface is provided with the eccentric adjusting screw of regulating the mechanical assembly error; The eccentric adjusting screw is threaded with the inner ring upper end face of bearing after passing connecting ring seat ring upper end face, and the spiro rod section of eccentric adjusting screw has the adjusting annular slot.Be threaded on the said connecting ring seat ring cylindrical sidewall and be connected the lock-screw of locking with beam-defining clipper.
Because said structure, the present invention has improved control accuracy and has prolonged service life.
Description of drawings
Device of the present invention can further specify through the indefiniteness embodiment that accompanying drawing provides.
Accompanying drawing 1 is the structural representation of the bulb connecting device of prior art X-ray production apparatus beam-defining clipper.
Accompanying drawing 2 is a structural representation of the present invention.
Accompanying drawing 3 is the explosive view of accompanying drawing 2.
Among the figure: 1, bulb connecting ring; 2, bearing; 3, location gear ring; 4, screw; 5, eccentric adjusting screw; 6, hold-down screw; 7, connecting ring pressing plate; 8, connecting ring seat ring; 9, lock-screw; 10, regulate annular slot.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Referring to the bulb connecting device of a kind of X-ray production apparatus beam-defining clipper in accompanying drawing 2 and the accompanying drawing 3, comprise that bulb connecting ring 1, the location gear ring 3, the bulb connecting ring 1 that are fixed on bulb connecting ring 1 bottom through screw 4 are arranged in the connecting ring seat ring 8; Wherein: between said bulb connecting ring 1 and the connecting ring seat ring 8 bearing 2 is installed, the outer ring of bearing 2 is pressed on gear ring 3 upper surfaces, location through the connecting ring pressing plate 7 that is fixed on connecting ring seat ring 8 upper surfaces.Through the setting of bearing 2, this connecting device can not wear and tear along with the passing of service time, just avoided metal fillings to wear away yet and dropped on beam-defining clipper inside, and external impurities drops at the inner pseudo-shadow of imaging that occurs of beam-defining clipper, causes the phenomenon of mistaken diagnosis to the doctor.Thereby improved control accuracy.Because more the frictional force of dynamic friction is less, also just prolonged the service life of connecting device.
The said connecting ring pressing plate 7 of the foregoing description is fixed on connecting ring seat ring 8 upper surfaces through hold-down screw 6.
For reducing rigging error; Improve installation accuracy; The said connecting ring seat ring of said structure 8 upper surfaces are provided with the eccentric adjusting screw 5 of regulating the mechanical assembly error; Eccentric adjusting screw 5 is threaded with the inner ring upper end face of bearing 2 after passing connecting ring seat ring 8 upper end faces, and the spiro rod section of eccentric adjusting screw 5 has the annular slot 10 of adjusting.Eccentric adjusting screw about 5 is finely tuned bulb, makes the small relatively rotation of bulb to compensate mechanical alignment error.
Be connected with the effective of beam-defining clipper for improving this connecting device, being threaded on the said connecting ring seat ring 8 cylindrical sidewalls of the foregoing description is connected the lock-screw 9 of locking with beam-defining clipper.Through lock-screw 9 beam-defining clipper is locked on the connecting ring seat ring 8 cylindrical sidewalls, connecting ring seat ring 8 can rotate in the bearing effect, also just makes beam-defining clipper to rotate along bulb according to actual needs.
In sum, this structure has improved control accuracy and has prolonged service life.
