Abstract
The utility model discloses an electromagnetism vibration excitation device, including the barrel, the top of barrel is connected with the upper cover, and the bottom is connected with the base, and the upper cover bottom is connected with the support, installs the electro -magnet on the support, and the below of electro -magnet is equipped with the drive hammer, and the electro -magnet still is connected with the socket. The bottom of base is equipped with the locating cone. The device can be under signal of telecommunication effect to the mode of putting the drive hammer is put forward to the electro -magnet, realizes the automatic vibration of being surveyed the component that arouses, provides the excitation means that suit with analysis component vibration characteristic for automatic acquisition. And the the device operation is reliable and stable, sturdy and durable.
Description
Technical field
This utility model relates to a kind of electromagnetic exciting device, can be used for the natural frequency of vibration of instantaneous aroused vibration method test member.
Background technology
When by the natural frequency of vibration of instantaneous aroused vibration method test member, the most first tap component with hand-held hammer and produce transient oscillation, then gather and analyze vibrational waveform and draw the natural frequency of vibration of component.But the occasion at automatic test, it is necessary to produce transient oscillation with a kind of exciting device automatically.
Summary of the invention
The purpose of this utility model is for problem above, it is provided that a kind of electromagnetic exciting device, it is possible in the vibration that under signal of telecommunication effect, can automatically excite tested component.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of electromagnetic exciting device, including cylinder, the top of cylinder connects upper cover, bottom connects base, and connecting bottom upper cover has support, and support is provided with electric magnet, the lower section of electric magnet is provided with hammer, and electric magnet is also associated with socket.
The bottom of described base is provided with locating cone.
The lower end of described locating cone is most advanced and sophisticated, and upper end is fixing with base to be connected.
The electromagnetic force during energising of described electric magnet is more than the gravity of hammer.
Described support is L-type, and its one end and upper cover are fixing to be connected, and one end is positioned at cylinder, and fixes with electric magnet and be connected.
Described electric magnet be can hot-wire coil, lower central is provided with through hole, and the top of hammer is provided with handle, and the internal diameter of through hole is more than the external diameter of handle.
Described cylinder is all connected by threaded engagement with base with upper cover and cylinder, and socket is arranged on and covers.
During this utility model energising, electric magnet produces electromagnetic force, mentions hammer, then unclamps hammer during power-off, is allowed to clash into base and produces vibration, it is achieved thereby that exciting automatically.Its each ingredient is connected by screw thread and screw rod, easy accessibility.Electric magnet, these fragile and loosely connected partial encapsulation of hammer are got up by its closure being made up of cylinder, upper cover and base, so that this device globality is strong, sturdy and durable.Locating cone may be inserted into measured body, prevents the exciting device displacement because repeatedly exciting causes.
This utility model, owing to using above-mentioned design, can realize automatic exciting, and globality is strong, easy to use, sturdy and durable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Further illustrate this utility model below in conjunction with embodiment, but the scope that this utility model claims is not limited to the scope that embodiment is stated.
As it is shown in figure 1, a kind of electromagnetic exciting device, including cylinder 1, the top of cylinder 1 connects upper cover 2, and bottom connects base 3, and connecting bottom upper cover has support 4, being provided with electric magnet 5 on support 4, the lower section of electric magnet 5 is provided with hammer 6, and electric magnet 5 is also associated with socket 7.
The bottom of described base is provided with locating cone 8.
The electromagnetic force during energising of described electric magnet is more than the gravity of hammer.
Cylinder is a cylindric thing, and two ends are provided with screw thread；Upper cover is a round pie thing, which is provided with screw thread, and center is provided with circular hole, screw；Base is steel one round pie thing, which is provided with screw thread, and center is provided with screw；Support is " L " shape steel thing, and its both sides are provided with screw, circular hole；Electric magnet be can hot-wire coil, hollow, energising produce electromagnetic force, after power-off electromagnetic force disappear；Hammer is a steel band handle hammer shape thing；Socket is circular aviation socket；Locating cone is a steel cone, and one end is provided with screw thread.The upper and lower two ends of cylinder are connected with upper cover and base respectively by screw thread；One limit of support is attached to, at the medial center of upper cover, be connected with upper cover by screw rod, and another limit of support is fixed with electric magnet by screw rod；The power line of electric magnet is welded on the binding post of socket；The pommel of hammer inserts the middle vacancy of electric magnet, and the other end contacts with the inner surface of base；Socket is fixed on the center of upper cover；Locating cone is threadedly secured at the outer side center of base.
During use, if measured body is soft material, first this electromagnetic exciting device being steadily positioned over measured body surface, locating cone inserts measured body simultaneously；Then pass through socket and access power supply；Then, controlling the break-make of power supply, during energising, electric magnet produces electromagnetic force, mentions hammer, then unclamps hammer during power-off, is allowed to fall to clashing into base generation vibration, thus realizes exciting.This utility model can also pass through programmable power supply break-make, thus realizes automatization.If measured body is stiff materials, should not punch, locating cone during use, can be taken off, with glue by bonding with measured body surface for the base lower surface of electromagnetic exciting device, play positioning action.
