Abstract
The invention discloses a dismounting type anode target device of an open type microfocus X-ray tube. An O-shaped ring is arranged on a track tube, the inner wall at one end of a head of the track tube is screwed into a pinhole sleeve, which is internally provided with a pin hole, an eccentric hole of a target cover is provided with an anode target, the target cover is arranged on the track tube and fixed on the O-shaped ring, and a gland, a spring and a cushion block are sleeved on the track sleeve. Because the target cover for positioning anode target is eccentric, different positions of the anode target can be rotated to the position of an X-ray focus as long as loosening the target cover and rotating the anode target by using a special tool, the anode target is very simple and rapid to replace and can be screwed down as long as placing the new anode target into the X-ray tube, so that the defect that only one target material can be used for one X-ray tube of the traditional X-ray tube is overcome, and meanwhile, the problem that the anode target is scrapped once damaged is solved also. According to the invention, the utilization rate of the expensive anode target is improved, and economic benefits are obvious.
Description
Technical field
The present invention relates to the parts of the X-ray tube that a kind of Non-Destructive Testing uses, specifically relate to a kind of reassembling type plate target device of open microfocus X-ray pipe.
Background technology
The anode of X-ray tube is the part producing X ray, the anode bodies high by the plate target of the electronic impact of bearing from cathode emission, thermal conductivity and anode cap three part are formed, plate target by cast welding tightly on the anode body, the position that the plate target of this structure is knocked can not change, the utilance of plate target is low, and can not change.Once plate target damages, cannot keep in repair, whole X-ray tube is all scrapped; If desired use the ray tube of different target, then each target will a ray tube.
Summary of the invention
The problem of plate target can not be changed for X-ray tube, the invention provides a kind of diverse location that not only can be used plate target by rotation, can also accomplish to change plate target quickly and easily, substantially increase the reassembling type plate target device of plate target utilance.
Solving the problems of the technologies described above taked concrete technical measures is:
A kind of reassembling type plate target device of open microfocus X-ray pipe, it is characterized in that: be made up of target cover 1, gland 2, plate target 3, O type circle 4, track pipe 5, pin hole 6, spring 7, pin hole cover 8 and cushion block 9, wherein: mounting O-shaped rings 4 on track pipe 5, pin hole cover 8 is screwed at the inwall of track pipe 5 head one end, pin hole 6 is loaded in pin hole cover 8, plate target 3 is loaded in the eccentric orfice of target cover 1, target cover 1 is arranged on track pipe 5 and by plate target 3 and is fixed on O type circle 4, and gland 2, spring 7 and cushion block 9 are enclosed within track pipe 5.
Beneficial effect of the present invention: because the target cover of the positioning anode target in X-ray tube is eccentric, therefore only target cover need be unscrewed, use specific purpose tool rotating anode target, change the position that X ray clashes into target surface, just the diverse location of plate target can be forwarded to the position of x-ray focus, the life-span of plate target can be improved by multiple rotary, improve the utilance of expensive plate target, cost-saving, remarkable in economical benefits.After plate target damages, also very simple and quick during replacing target, as long as back out target cover, new target can be put into, just can complete the replacing of target, overcome often kind of target by a kind of drawback of X-ray tube, can only also solve plate target once damage a difficult problem of just scrapping simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic diagram that the present invention is arranged in open microfocus X-ray pipe.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
A kind of reassembling type plate target device of open microfocus X-ray pipe, as shown in Figure 1, be made up of target cover 1, gland 2, plate target 3, O type circle 4, track pipe 5, pin hole 6, spring 7, pin hole cover 8 and cushion block 9, wherein: track pipe 5 makes of pure aluminum material, an O type circle 4 installed by track pipe 5, is screwed into pin hole cover 8 at the inwall of track pipe 5 head one end, in pin hole cover 8, load pin hole 6, molybdenum elected as by the material of pin hole 6, the distance of pin hole 6 adjustable and plate target 3.The target cover 1 that duralumin makes is screwed on track 5 by screw thread, plate target 3 there is a boss, with the middle eccentric orfice location of target cover 1, by threaded together plate target 3 is fixed on the O type circle 4 on track pipe 5, gland 2, spring 7 and cushion block 9 are enclosed within track pipe 5, in order to location.Because the interfix hole of target cover 1 is eccentric, to the point at the center of positive rail pipe 5, i.e. focus, it is not the center of plate target 3, therefore unscrew target cover, with specific purpose tool rotating anode target 3, just the diverse location of plate target 3 can be forwarded to the position of X-ray tube focus, improve the utilance of expensive plate target 3, remarkable in economical benefits.If when plate target 3 damages or needs to change the target of plate target 3, as long as back out target cover 1, take out the plate target 3 of damaged plate target 3 or needs replacing, new plate target 3 is put into target cover 1, tighten target cover 1, just can complete the replacing of plate target 3, the X-ray tube replacing plate target 3 of this structure is very simple and quick.
Figure 2 shows that the present invention is arranged on the schematic diagram in open microfocus X-ray pipe.Track pipe 5 in the present invention 4 hexagon socket countersunk flat cap head screws are fixed on ray tube top cover 10, track pipe 5 is through the focusing arrangement 11 be arranged in X-ray tube, be enclosed within track pipe 5 with these three parts of gland 2, spring 7 and cushion block 9 and locate the distance with focusing arrangement 11, another head end of track pipe 5 inserts in the electricity speed axle 12 of X-ray tube, and electric fast axle 12 seat that is fixed is fixed on the upper cover 14 of X-ray tube.High-velocity electrons are sent by filament, through track pipe 5, beat on plate target 3, produce X ray.
