Description
Technical field
The utility model relates to a kind of servicing unit measuring klystron field coil internal magnetic field distribution curve, especially relates to a kind of klystron measurement of magnetic field frame.
Background technology
The klystron of each model operationally all needs corresponding axis magnetic field curve, and the structure of often kind of model klystron, shape, size etc. are all different, and therefore, the klystron of different model needs different field coils.The axis magnetic field of often kind of field coil all requires to design according to the Distribution of Magnetic Field of regulation.The measuring position of Distribution of Magnetic Field is generally on the axial direction of the central shaft of field coil.The Distribution of Magnetic Field of klystron field coil, can affect the focusing effect of electron beam in klystron.If the Distribution of Magnetic Field change of field coil, will change Electron Beam Focusing effect, cause electron beam to defocus, cause the klystron life-span to end.So, also need to carry out careful adjustment to Distribution of Magnetic Field according to the produced field coil of design technology, when measuring the Distribution of Magnetic Field of field coil, due to the probe very thin very long (about 1000mm) of magnetometer, and the probe external diameter of the internal diameter relative magmetometer of field coil is just very large, and the height of field coil very high (more than hundreds of millimeter), in whole height, do not have auxiliary mould to be difficult to the probe of magnetometer to be fixed on the axial direction of field coil central shaft.If the position of magnetometer in field coil axis is fixed bad, the data recorded are not just very accurate.Also can affect the distribution in magnetic field in addition to the shielding action in magnetic field at field coil two ends object.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides that a kind of structure is simple, the klystron measurement of magnetic field frame of the Distribution of Magnetic Field of assembling easy, Measurement accuracy corresponding model klystron field coil.
The technical solution adopted in the utility model is: a kind of klystron measurement of magnetic field frame, comprise magnetic shield panel and lower magnetic shield panel, lower magnetic shield panel is arranged on the below of magnetic shield panel, it is characterized in that: be connected with support bar between described upper magnetic shield panel with lower magnetic shield panel and support, transition rings is mounted with in the middle part of described upper magnetic shield panel, lower transition rings is mounted with in the middle part of described lower magnetic shield panel, upper transition rings be equipped with through hole in the middle part of lower transition rings and position is corresponding, guide pipe is inserted with between upper transition rings and lower transition rings through hole, guide pipe lower end is inserted in the through hole of lower transition rings, upper end extend in the through hole of transition rings.
As preferably, described support bar lower end is inserted in lower magnetic shield panel fixing, and upper end is through upper magnetic shield panel and use fastening nuts.
As preferably, described support bar quantity is 3, and all and be distributed between magnetic shield panel and lower magnetic shield panel.
As preferably, can install measurement of magnetic field probe in described guide pipe, guide pipe internal diameter size and measurement of magnetic field outside dimension of popping one's head in matches.
As preferably, the material of described upper magnetic shield panel, lower magnetic shield panel, upper transition rings, lower transition rings, guide pipe, support bar and nut is non-magnetic material.
As preferably, described upper magnetic shield panel is consistent with the upper magnetic shield panel of corresponding klystron and lower magnetic shield panel material with the material of lower magnetic shield panel.
The beneficial effect that the utility model obtains is: the utility model is by adopting upper magnetic shield panel with lower magnetic shield panel and being connected support by support bar, and structure is simple; By transition rings and lower transition rings on fixing in the middle of upper magnetic shield panel and lower magnetic shield panel, and arrange guide pipe in the middle part of upper transition rings and lower transition rings, guide pipe internal diameter size and measurement of magnetic field outside dimension of popping one's head in matches, and makes test data more accurate.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model;
Wherein, transition rings, 7-nut under magnetic shield panel, 3-support bar, 4-guide pipe, the upper transition rings of 5-, 6-under the upper magnetic shield panel of 1-, 2-.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of klystron measurement of magnetic field frame of the present utility model comprises: upper magnetic shield panel 1, lower magnetic shield panel 2, upper transition rings 5, lower transition rings 6 and nut 7, upper magnetic shield panel 1 and lower magnetic shield panel 2 three support bars 3 are evenly connected support, and the planform of the planform of upper magnetic shield panel 1 and lower magnetic shield panel 2, size, distance, material and upper and lower two magnetic shield panels of corresponding klystron, size, distance, material are consistent; Support bar 3 lower end is inserted in lower magnetic shield panel 2 to be threaded connection and is fixed, and upper end is also fastening with nut 7 through upper magnetic shield panel 1, and magnetic shield panel 1 upper surface is stretched out in support bar 3 upper end, convenient operation.
Transition rings 5 is mounted with in the middle part of upper magnetic shield panel 1, lower transition rings 6 is mounted with in the middle part of lower magnetic shield panel 2, upper transition rings 5 be equipped with through hole in the middle part of lower transition rings 6 and position is corresponding, guide pipe 4 is inserted with between upper transition rings 5 and lower transition rings 6 through hole, guide pipe 4 lower end is inserted in the through hole of lower transition rings 6, and upper end extend in the through hole of transition rings 5; Guide pipe 4 can installation shaft to measurement of magnetic field instrument probe, the internal diameter of guide pipe 4 is consistent with corresponding axial magnetic field probe of tester external diameter, and bigger.
