Description
Technical field
This utility model belongs to the electric multiblade optical grating technical field of industrial radiation bundle, relates to a kind of multi-leaf raster leaf driving mechanism.
Background technology
At present, in current radiotherapy field, electric multiblade optical grating (MLC) is widely used in radiotherapy, comprises Intensity Modulation Radiated Therapy (IMRT) and conformal radiation therapy.The target that medical circle is pursued always will meet except user demand except the function of equipment, also requires equipment pleasantization.Multi-leaf raster leaf driving device blade installation common at present, in blade casing, can horizontally slip.Motor is fixed on the motor plate in left side, and one end of screw mandrel is connected with motor output shaft by shaft coupling, and the other end is through nut, and nut is fixed on blade, when electric machine rotation, and screw mandrel driven vane nut and vane reciprocation.
The driving mechanism of existing multi-leaf raster leaf, screw mandrel is slender type, and linearity is difficult to ensure, screw mandrel is single support simultaneously, when screw mandrel runs up, can produce vibration, and vibration is very serious, multi-leaf optical grating total noise of centrifuge is very large, can produce some adverse influences at heart to patient.
Therefore, for the defect that above-mentioned prior art exists, be necessary to develop research in fact, to provide a kind of scheme, to reduce vibration & noise, reduce noise to patient's adverse effect at heart.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of multi-leaf raster leaf driving mechanism, to reduce vibration & noise, reduces noise to patient's adverse effect at heart.
For achieving the above object, the technical solution of the utility model is:
A kind of multi-leaf raster leaf driving mechanism, includes motor, shaft coupling, motor mounting plate, screw mandrel, nut, casing, support ring and casing; Wherein, motor is arranged on motor mounting plate, and motor mounting plate is fixedly connected with casing; One end of shaft coupling connects with the output shaft of motor, and the other end is connected with screw mandrel; Support ring is fixed in the elongated slot of blade; Blade is placed in the gathering sill of casing.
Further, be unthreaded hole inside described support ring, be fixed in blade, the location of screw mandrel can be assisted, increase a support, reduce silk vibration of bar and noise.
Further, described blade is provided with square opening, and screw mandrel is through nut, and nut is fixed in the square opening of blade.
Further, described gathering sill is arranged at box inside, and blade can move in groove.
Compared to prior art, this utility model multi-leaf raster leaf driving mechanism side that overhang by screw mandrel increases a support ring, reduces screw mandrel cantilevered length, is conducive to the degree of crook reducing screw mandrel, reduces vibration & noise.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only this utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, connect integratedly, also can be removably connect; It can be the connection of two element internals; Can be directly be connected, also indirectly can be connected by intermediary, for the ordinary skill in the art, concrete condition can understand the concrete meaning of above-mentioned term in this utility model.
Please refer to shown in Fig. 1, Fig. 2, this utility model multi-leaf raster leaf driving mechanism includes motor 1, shaft coupling 2, motor mounting plate 3, screw mandrel 4, nut 5, casing 6, support ring 7, blade 8.Wherein, motor 1 is arranged on motor mounting plate 3, and motor mounting plate 3 is fixedly connected with casing 6; One end of shaft coupling 2 connects with the output shaft of motor, and the other end is connected with screw mandrel 4; Blade 8 is provided with square opening, and screw mandrel 4 is through nut 5, and nut 5 is fixed in the square opening of blade 8; Support ring is fixed in the elongated slot of blade 8; Blade 8 is placed in the gathering sill of casing 6.
During work, the motor 1 be fixed on motor mounting plate 3 drives screw mandrel 4 to rotate by shaft coupling 2, and the nut 5 be fixed on blade forms feed screw nut pair with screw mandrel 4, is responsible for the rectilinear motion rotary motion of screw mandrel 4 being converted to blade, have gathering sill inside casing 6, blade moves in groove.
Be unthreaded hole inside support ring 7, be fixed in blade.When blade movement is to right side, although screw mandrel can depart from support ring, owing to there being the support of nut 5, screw mandrel overhang be not very long, if but blade movement to left side time, if there is no support ring 7, the overhanging of screw mandrel can become very long, and screw mandrel, when high speed rotating, can produce very strong vibration & noise.There is support ring 7, the location of screw mandrel can have been assisted, increased a support, reduced silk vibration of bar and noise.
Motor 1 described in the utility model is arranged on motor mounting plate 3, and motor mounting plate 3 is fixedly connected with casing 6; One end of shaft coupling 2 connects with the output shaft of motor, and the other end is connected with screw mandrel 4; Screw mandrel 4 is through nut 5, and nut 5 is fixed in the square opening of blade 8; Support ring is fixed in the elongated slot of blade 8; Blade 8 is placed in the gathering sill of casing 6.When blade is to left movement, on the right side of screw mandrel, termination can be inserted in support ring 7, and screw mandrel becomes dual-gripper by single support, is conducive to the degree of crook reducing screw mandrel, reduces vibration & noise.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
