Abstract
A perforation type moving coil framework without a table-board comprises two enclosing frames which are arranged in parallel and a ribbed slab part connected between the two enclosing frames, wherein the ribbed slab part comprises at least three ribbed slabs which are rotationally arranged round a framework center shaft line at equal angles and connected with one side gathered on the framework center shaft line, a coiling position is formed by the outer edges of the ribbed slabs, and the front enclosing frame and the rear enclosing frame are provided with disconnecting prevention baffle surfaces corresponding to the coiling position. The utility model solves the problem that the moving speed, the shocking displacement, the acceleration, and the like of a moving coil are restrained to influence the experiment precision of an electric shock test machine due to the influence of the self-structure shape of the moving coil framework.
Description
Technical field
The utility model relates to the impact test apparatus of environmental mechanics test, the penetration type moving coil framework that particularly a kind of electric impacting platform is used.
Background technology
Shock table mainly is to be used for analog equipment to suffer the testing equipment of shock environment in use, loading and unloading or transportation, to determine the adaptability of this product to various impulsive forces, and evaluate the integrity of its structure, for the quality of examining this product provides rational foundation.Therefore, be widely used in fields such as weaponry, electromechanical equipment, instrument and meter, household electrical appliance.
The structure and the electric vibration table of electric impacting testing table are similar, and it utilizes the Electromagnetic Drive principle design, by constant D.C. magnetic field be arranged in that the electric power that interaction produced that this magnetic field is connected with the coil of certain alternating current drives.Its basic structure mainly is made up of stage body, field copper, moving-coil, bearing guiding device etc., and described moving-coil is made of moving coil framework and drive coil as producing the critical piece that impacts, and an end of moving coil framework is the work top that test specimen is installed; Stage body is the magnetic cylinder member of a tubular, field copper be fixed in the stage body tube circumferentially, moving-coil is embedded in the stage body by bearing guiding device, whole stage body is supported on the bearing again.During work, in the field coil of stage body, feeding DC current---exciting current produces very strong D.C. magnetic field in the annular space (working gas gap) of stage body; Pass to exchange current in the drive coil of moving-coil, the drive current of this interchange and the direct current stationary magnetic field among the working gas gap interact and produce electric power---the exciting force of alternation, this exciting force is delivered to through moving coil framework on the work top that test specimen is installed, and produces impact to promote test specimen.
The moving coil framework of above-mentioned electric impacting moving-coil that testing table adopts is for as shown in Figure 1, by work top 1, floor 2 with enclose that frame 3 is one-body molded to be constituted, floor 2 is three, integrally formed taper type, work top 1 is arranged on the top of floor 2, encloses the bottom that frame 3 is arranged on floor 2.When assembling is used, drive coil on the moving-coil is wound on the lower edge of enclosing frame 3, when work, owing to be subjected to the influence of moving coil framework self structure, the taper type of floor has limited the stroke of moving-coil, thereby makes this electric impacting testing table be restricted aspect movement velocity, impact displacement and the acceleration.
Summary of the invention
The utility model provides a kind of no table top penetration type moving coil framework, its purpose mainly is to solve in the prior art because of influenced by moving coil framework self structure shape, and make the aspects such as movement velocity, impact displacement and acceleration of moving-coil be restricted, thereby influence the trial stretch problem of electric impacting testing table.
For achieving the above object, the technical solution adopted in the utility model is: a kind of no table top penetration type moving coil framework, enclose frame and the two floor portions that enclose between frame that are connected constitute by two that be arranged in parallel, described floor portion is made of at least three floors, these floors are arranged around frame center's axis equal angles rotation, and converge connection with the one side on frame center's axis, the outer rim of these floors constitutes a coil winding position, and two are enclosed the corresponding coiling of frame position and are being circumferentially with the anticreep block face.
The further change interpretation of related content in the technique scheme is as follows:
1, in the such scheme, the connecting portion upper edge central axis that converges of described floor is established perforation.This perforation is used to wear guide pole.
2, in the such scheme, described floor and the described frame that encloses are structure as a whole.Perhaps, described floor and the described frame that encloses are connected to one.
3, in the such scheme, described anticreep face refer to enclose be provided with on the frame prevent to be wound on the plane that the drive coil on the skeleton comes off at work.
4, in the such scheme, the converging the connecting portion two ends and can be designed to cave in of described floor.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model adopts the moving coil framework of no table top, enclose connection rib board between frame at two that be arranged in parallel, two enclose the impact stroke that distance between frame has determined moving-coil.So just make and adopt the electric impacting testing table of this moving coil framework can obtain bigger impact displacement, higher movement velocity and higher acceleration, make the trial stretch of whole electric impacting testing table enlarge, broken through the bottleneck of prior art.
2, the utility model is skillfully constructed, and is simple in structure, and it is little to have overcome existing moving coil framework impact displacement, the technical barrier that movement velocity and acceleration are lower.
Description of drawings
Accompanying drawing 1 is existing moving coil framework structural representation;
Accompanying drawing 2 is the utility model structural representation;
Accompanying drawing 3 is the combination synoptic diagram of the utility model and stage body.
In the above accompanying drawing: 1, work top; 2, floor; 3, enclose frame; 4, perforation; 5, anticreep face; 6, magnetic cylinder ring; 7, central magnetic pole; 8, guide pole; 9, pole plate; 10, field coil; 11, drive coil.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment:
As Fig. 2, shown in Figure 3, enclose frame 3 and the two floor portions that enclose 3 of frames that are connected constitute by two that be arranged in parallel, described floor portion is made of three floors 2, these floors 2 are arranged around frame center's axis equal angles rotation, and on frame center's axis, converge connection with the one side, the outer rim of these floors constitutes a coil winding position, and two are enclosed frame 3 corresponding coiling positions and are provided with anticreep block face 5.Described floor 2 is structure as a whole with the described frame 3 that encloses.
Described anticreep face 5 refer to enclose on the frame 3 be provided with prevent to be wound on the plane that the drive coil 11 on the skeleton comes off at work.
The connecting portion upper edge central axis that converges of three floors 2 is established perforation 4.This perforation 4 is used to wear guide pole 8.Cave in the connecting portion two ends of converging of three floors 2, this caves in and is used for fixedly stepping down of guide pole 8.
The inner edge of described at least three floors 2 forms perforation 4 in splicing place, and this perforation 4 is used to wear guide pole 8.Described floor 2 two ends end faces form step towards perforation 4.
