Description
Technical field
The present invention relates to the company of electric vibration testing equipment, more particularly to a kind of electric vibration table central magnetic pole and short-circuited conducting sleeve
Binding structure.
Background technology
The raising required with product testing, electric vibration table is ripe for industry as conventional dynamic environmental test equipment
Know.
Electric vibration table can produce equiva lent impedance when producing high-frequency excitation power in magnetic circuit system, and prior art often exists
One layer of short-circuited conducting sleeve is welded on magnetic cylinder or central magnetic pole（The higher metal copper ring of conductance）, such as Publication No. CN101377446
Chinese patent application discloses a kind of attachment structure of short-circuited conducting sleeve, and short-circuited conducting sleeve is directly anchored into center magnetic by cyclic adapting piece
Pole（Magnetic core）Outer surface, the structure can improve welding efficiency, but in practice, in order to improve magnetic field force, central magnetic pole and magnetic
Gap very little between cylinder（The setting of gapped magnetic field is often through scientific algorithm）, and be provided with gap can be for moving-coil
The space of motion, directly being fixed on central magnetic pole surface can cause gapped magnetic field to subtract with certain thickness short-circuited conducting sleeve and connector
It is small, magnetic field exciting force is influenceed, and make moving-coil space smaller, or even interference failure occurs.
The content of the invention
The purpose of the present invention, is to solve the existing irrational problem of short-circuited conducting sleeve welding structure, prevents jigging platform moving coil from doing
Relate to.
To achieve the above object, the invention discloses a kind of electric vibration table central magnetic pole and the attachment structure of short-circuited conducting sleeve,
The side wall of the central magnetic pole forms groove in a circumferential direction, and the short-circuited conducting sleeve is fixedly installed in the groove.
The attachment structure also includes connector, and the connector is arranged in the groove, and the short-circuited conducting sleeve passes through institute
Connector is stated to be fixedly installed in the groove.
Connector side wall forms recess in a circumferential direction, and the short-circuited conducting sleeve is fixedly installed on the recess.
At least one rib is formed at the connector top and/or bottom.
The short-circuited conducting sleeve is welded on the recess.
At least one screw is set on the connector, and the connector is fixed in the groove by fastener.
Or, at least one screw is set on the short-circuited conducting sleeve, and the short-circuited conducting sleeve is fixed on the groove by fastener
It is interior
Compared with prior art, electric vibration table central magnetic pole disclosed by the invention and the attachment structure of short-circuited conducting sleeve are rationally simple
Single, easy to operate, short-circuited conducting sleeve can not change gapped magnetic field after installing, and also not result in moving-coil movement interference failure.
Brief description of the drawings
Fig. 1 is the central magnetic pole structural representation in the present invention.
Fig. 2 is the structural representation of the embodiment of the present invention one.
Fig. 3 is the structural representation of the embodiment of the present invention two.

Embodiment
Below in conjunction with the drawings and specific embodiments, the connection of electric vibration table central magnetic pole and short-circuited conducting sleeve to the present invention
Structure is described in detail.
Disclosed electric vibration table central magnetic pole and the attachment structure of short-circuited conducting sleeve, its central idea is described
The side wall of central magnetic pole forms groove in a circumferential direction, and the short-circuited conducting sleeve is fixedly installed in the groove.
As shown in figure 1, the cylindrical structure of the central magnetic pole 1, its section is in inverted " t ", the less master of its upper diameter
The side wall of body 11 forms groove 12, the groove 12 and side wall one step of formation of the central magnetic pole 1 in a circumferential direction
Portion.
Fig. 2 shows the preferred embodiments of the present invention, and the attachment structure includes short-circuited conducting sleeve 2, connector 3, the short circuit
Ring 2 is metal copper ring, and the connector 3 includes first surface 31 and second surface 32, the first surface 31 and the groove
12 bottom surface is fully mated, and a recess is formed on the second surface 32, and the short-circuited conducting sleeve 2 is welded in the recess, institute
It is rectangular configuration or other structures installed suitable for the short-circuited conducting sleeve 2 to state recess cross section.
In the present embodiment, the upper and lower part of the connector 3 respectively forms one relative to the reinforcement that the recess is protruded
Each uniform intervals set a plurality of screws 34 in portion 33, the rib 33 of two ring-types, by mounting screw by the connector 3
In the main body for being fixed on the central magnetic pole 1, screw 34 is arranged on to the welding brought when rib avoids solder shorts ring
It is difficult.
In the present embodiment, the rib 33 can only set a screw according to the diameter of central magnetic pole, and described
Recess on the second surface of connector 3 can also be " L " or inverted "L" shaped structure, that is, form a rib, a rib circle
Screw is set also to fix the connector in circumferential direction.
First the short-circuited conducting sleeve 2 can be welded in the connector 3 in the present embodiment manufacturing process, then by special
The connector for being welded with short-circuited conducting sleeve is looped around in the recess of the central magnetic pole 1 by frock, finally by screw by the connection
Part 3 is fixed in the groove 12.
Fig. 3 is the structural representation of the embodiment of the present invention two, and the present embodiment is similar to the structure of embodiment one, and it, which is distinguished, is to connect
The structure of fitting, connector is also integrally platy structure, does not form recess and rib thereon, and screw runs through short-circuited conducting sleeve and company
Fitting, screw is fixedly connected through short-circuited conducting sleeve and connector with central magnetic pole, easy for installation, does not also interfere with gapped magnetic field empty
Between.
Fig. 4 is the structural representation of the embodiment of the present invention three, and the present embodiment is similar to the structure of embodiment two, and its difference is do not have
There is the screw in setting connector, screw to be directly fixedly connected through short-circuited conducting sleeve with central magnetic pole, installation is also convenient for.
The present invention is simple in construction, easy to operate, can not change gapped magnetic field after short-circuited conducting sleeve and central magnetic pole installation, also not
Moving-coil movement interference failure can be caused.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all cover within the scope of the present invention.
