Abstract

The invention discloses a kind of actuation generator, belong to field of measuring technique, including magnetostriction apparatus, also include pressure applying means and mobile device, the magnetostriction apparatus is fixed on the mobile device, pressure applying means are arranged on magnetostriction apparatus top, and act directly on the operation button of magnetostriction apparatus, the pressure applying means include support frame and are fixed on support frame to stretch descending mechanism, the mobile device is motor vehicle, and support frame as described above is removably attached on motor vehicle by fastener.The present invention starts magnetostriction apparatus by pressure applying means and completes to tap operation, and excitation is accomplished manually so as to substitute, because its active force is provided by pressure applying means, can be than artificial accurate and quick, so as to improve measuring accuracy and efficiency;And make magnetostriction apparatus that there is mobility by moving cart, the test of large-sized object can be completed.

Description

A kind of actuation generator
Technical field
The invention belongs to field of measuring technique, and in particular to a kind of actuation generator.
Background technology
The excitation that prior art needs when carrying out a certain test is generally realized by manually tapping tester.The program is deposited In two problems:One is that percussion dynamics is not accurate enough, it is difficult to every time can lotus root conjunction, influence measuring accuracy and speed;Two be mobile Distance and speed are limited, for large test thing because the muscle power limitation of thwacker is difficult thoroughly to be tested.
In view of the above-mentioned problems, if a kind of actuation generator can be proposed, percussion can be automatically performed, and tap dynamics it is controllable and It is removable, so that the accurate generation instead of being accomplished manually excitation.
The content of the invention
In view of this, it is an object of the invention to provide a kind of actuation generator, taken with to solve prior art and manually struck The measuring accuracy that hits presence is poor, low efficiency and the problem of bad adaptability.
To reach above-mentioned purpose, the present invention provides following technical scheme:
A kind of actuation generator, including magnetostriction apparatus, in addition to pressure applying means and mobile device, the mangneto Retractor device is fixed on the mobile device, and pressure applying means are arranged on magnetostriction apparatus top, and act directly on mangneto On the operation button of retractor device, the pressure applying means include support frame and the descending mechanism of stretching being fixed on support frame, institute Mobile device is stated for motor vehicle, support frame as described above is removably attached on motor vehicle by fastener.
Further, the descending mechanism of stretching is cylinder or oil cylinder or electric pushrod, the cylinder or oil cylinder or electric pushrod Pistons end is acted perpendicularly on the operation button of magnetostriction apparatus.
Further, the pistons end of the cylinder or oil cylinder or electric pushrod is provided with cushion pad.
Further, the end of the operation button of the magnetostriction apparatus is provided with back-moving spring.
The beneficial effects of the present invention are:
The present invention by pressure applying means start magnetostriction apparatus complete tap operation so that substitute be accomplished manually it is sharp Encourage generation, because its active force is provided by pressure applying means, can than artificial accurate and quick so that improve measuring accuracy and Efficiency;And make magnetostriction apparatus that there is mobility by moving cart, large test object such as airport, bridge etc. can be completed Test, widened the scope of application, its adaptability is strengthened.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke To be instructed from the practice of the present invention.The present invention target and other advantages can be realized by following specification and Obtain.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carried out Explanation:
Fig. 1 is structural representation of the invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in figure 1, a kind of actuation generator, including magnetostriction apparatus 1, pressure applying means 2 and mobile device 3, Magnetostriction apparatus is prior art, a kind of portable giant magnetostriction seismic source dress as disclosed in publication number CN101694973A Put, it at least includes shell 4, impact take-off lever 5 and the operation button 6 positioned at cover top portion, magnetostriction apparatus is fixed on shifting On dynamic device, pressure applying means are arranged on magnetostriction apparatus top, and act directly on the operation of magnetostriction apparatus by On button,
Specifically, pressure applying means include support frame 7 and be fixed on support frame to stretch descending mechanism 8, stretching descending mechanism 8 is The pistons end of cylinder or oil cylinder or electric pushrod, cylinder or oil cylinder or electric pushrod acts perpendicularly to the behaviour of magnetostriction apparatus Make on button, mobile device is motor vehicle, support frame is removably attached on motor vehicle by fastener, passes through motor vehicle It is mobile so that generator can move operation, so as to improve test scope and efficiency.
The present invention is acted directly on the operation button of magnetostriction apparatus by pressure applying means, and then starts mangneto Retractor device completes to tap operation, instead of artificial operation, and because its active force is provided by pressure applying means, and pressure applies dress The active force put is controllable, can be adjusted according to actual needs, makes it lotus root can be triggered to close between test object, so as to reach To more preferably test effect and efficiency;And make magnetostriction apparatus that there is mobility by moving cart, large-scale detection can be completed The test on object such as airport, bridge etc., it is to avoid prior art takes the artificial muscle power existed that taps to limit and can not complete certain The problem of a little large test things are tested, expands test scope, its adaptability is strengthened.
In the present embodiment, the pistons end of cylinder or oil cylinder or electric pushrod is provided with cushion pad 9, can by cushion pad 9 Shock loading causes damage to piston or impact take-off lever when reducing rigid contact, so as to improve security and extension uses the longevity Life, beneficial to reduction use cost.
In the present embodiment, the end of the operation button of magnetostriction apparatus is provided with back-moving spring 10, and is set by end The limited step 11 put carries out spacing, the original state of impact take-off lever is in specified extension elongation all the time.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
