Description
Technical field
The utility model relates to electric vibration testing equipment, particularly relates to the syndeton of a kind of electric vibration table central magnetic pole and short-circuited conducting sleeve.
Background technology
Along with the raising that product testing requires, electric vibration table as conventional dynamic environmental test equipment known by industry.
Electric vibration table can produce equiva lent impedance when producing high-frequency excitation power in magnetic circuit system, prior art often welds one deck short-circuited conducting sleeve (the metal copper ring that conductance is higher) on magnetic cylinder or central magnetic pole, as the publication number Chinese patent application that is CN101377446 discloses a kind of syndeton of short-circuited conducting sleeve, by cyclic adapting piece, short-circuited conducting sleeve is directly fixed on the outside surface of central magnetic pole (magnetic core), this structure can improve welding efficiency, but in reality, in order to improve magnetic field force, gap between central magnetic pole and magnetic cylinder very little (setting of gapped magnetic field is often through scientific algorithm), and in gap, be provided with the space that can be used for moving-coil to move, directly fixedly there is certain thickness short-circuited conducting sleeve on central magnetic pole surface and web member can cause gapped magnetic field to reduce, affect magnetic field exciting force, and make moving-coil space less, even there will be interference fault.
Utility model content
The purpose of this utility model, is to solve the irrational problem of existing short-circuited conducting sleeve welded structure, prevents jigging platform moving coil from interfering.
For achieving the above object, the utility model discloses the syndeton of a kind of electric vibration table central magnetic pole and short-circuited conducting sleeve, the sidewall of described central magnetic pole forms groove in a circumferential direction, and described short-circuited conducting sleeve is fixedly installed in described groove.
Described syndeton also comprises web member, and described web member is arranged in described groove, and described short-circuited conducting sleeve is fixedly installed in described groove by described web member.
Described web member sidewall forms recess in a circumferential direction, and described short-circuited conducting sleeve is fixedly installed on described recess.
At least one rib is formed at described web member top and/or bottom.
Described short-circuited conducting sleeve is welded on described recess.
Described web member is arranged at least one screw, described web member is fixed in described groove by securing member.
Or described short-circuited conducting sleeve is arranged at least one screw, described short-circuited conducting sleeve is fixed in described groove by securing member
Compared with prior art, the syndeton of electric vibration table central magnetic pole and short-circuited conducting sleeve disclosed in the utility model is rationally simple, easy to operate, and short-circuited conducting sleeve can not change gapped magnetic field after installing, and moving-coil also can not be caused to move interference fault.

Embodiment
Below in conjunction with the drawings and specific embodiments, the syndeton of electric vibration table central magnetic pole of the present utility model and short-circuited conducting sleeve is described in detail.
The electric vibration table central magnetic pole that the utility model discloses and the syndeton of short-circuited conducting sleeve, its central idea forms groove in a circumferential direction at the sidewall of described central magnetic pole, and described short-circuited conducting sleeve is fixedly installed in described groove.
As shown in Figure 1, described central magnetic pole 1 is in cylindrical-shaped structure, and its cross section is in falling " T ", and the sidewall of the main body 11 that its upper diameter is less forms groove 12 in a circumferential direction, and described groove 12 forms a stage portion with the sidewall of described central magnetic pole 1.
Fig. 2 shows preferred embodiment of the present utility model, described syndeton comprises short-circuited conducting sleeve 2, web member 3, described short-circuited conducting sleeve 2 is metal copper ring, described web member 3 comprises first surface 31 and second surface 32, described first surface 31 coordinates completely with the bottom surface of described groove 12, and described second surface 32 forms a recess 4, and described short-circuited conducting sleeve 2 is welded in described recess 4, described recess 4 cross section is rectangular configuration, also can be that other is suitable for the structure of described short-circuited conducting sleeve 2 installation.
In the present embodiment, the upper and lower of described web member 3 respectively forms a rib 33 given prominence to relative to described recess 4, in the rib 33 of two ring-types, each uniform intervals arranges a plurality of screw 34, by mounting screw, described web member 3 is fixed in the main body of described central magnetic pole 1, screw 34 is arranged on the welding difficulty brought when rib avoids solder shorts ring.
In the present embodiment, described rib 33 can only arrange a screw according to the diameter of central magnetic pole, and the recess 4 on described web member 3 second surface also can be " L " or inverted "L" shaped structure, namely form a rib, a rib circumferentially arranges screw and also can fix described web member.
Can first described short-circuited conducting sleeve 2 be welded in described web member 3 in the present embodiment manufacturing process, then by special frock, the web member being welded with short-circuited conducting sleeve is looped around in the recess 4 of described central magnetic pole 1, finally by screw, described web member 3 is fixed in described groove 12.
Fig. 3 is the utility model embodiment two structural representation, the present embodiment is similar to embodiment one structure, its difference is the structure of web member, web member entirety is also platy structure, it does not form recess and rib, and screw runs through short-circuited conducting sleeve and web member, and screw is fixedly connected with central magnetic pole with web member through short-circuited conducting sleeve, easy for installation, also can not affect gapped magnetic field space.
Fig. 4 is the utility model embodiment three structural representation, and the present embodiment is similar to embodiment two structure, and its difference is not arrange web member, and the screw in screw directly runs through short-circuited conducting sleeve and is fixedly connected with central magnetic pole, installs and also facilitates.
The utility model structure is simple, easy to operate, and short-circuited conducting sleeve and central magnetic pole can not change gapped magnetic field after installing, and moving-coil also can not be caused to move interference fault.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
