Abstract
The invention discloses an automatic flexible impact hammer module. The automatic flexible impact hammer module is composed of a control portion and an execution portion. The control portion is composed of a stepping motor, a shaft coupling, a cam driving shaft and a cam, provides a controllable power source for the automatic flexible impact hammer module and controls a hammering force and a hammering frequency; and the execution portion is mainly composed of a flexible hammer handle, a return spring, a standing seat and a hammerhead, the cam drives rotates to drive the flexible hammer handle to swing vertically, and the hammerhead realizes hammering motion. A force sensor at a hammerhead portion can measure the hammering force as excitation signals during mechanical modal analysis. The stepping motor is employed for control, the generated hammering force is enabled to be more stable and repeatable, the flexible hammer head is employed, the large hammering force is output while labor is saved, the overall structure is simple, and the manufacturing is convenient.
Description
Technical field
The present invention relates to a kind of automatic flexible power hammer module, particularly relate to one and drive tup to complete hammer by step motor control, the flexible hammer handle of dependence
The automatic flexible power hammer device hit.
Background technology
Model analysis is a kind of method in modern age of research structure dynamic trait, is the application in Engineering Vibration field of the system identification method.Mode is machine
The natural vibration characteristic of tool structure, generally uses mode experiment to measure the dynamic characteristic of frame for movement, obtain the natural frequency of structure, Mode Shape and
Modal damping, provides foundation for Analysis of Vibration Characteristic, vibrating failure diagnosis and the forecast of structural system and the optimization design of structural dynamic characteristic.
Modal test is frequently with hammering method, in hammering method is tested, hammers the tested frame for movement of percussion into shape by the power being provided with force transducer and encourages,
Measure the response acceleration signal of hammering frame for movement each point, try to achieve frame for movement finally by the exciting force signal of input and the acceleration signal of output
Transmission function, it is thus achieved that the vibration characteristics of frame for movement.The most important advantage of this method is the machinery measured by exciting bank (i.e. power hammer) discord
Structure is connected, and will not add any quality to structure, not affect the dynamic characteristic that frame for movement is final.
At present, hammering method test is to be beaten by geodesic structure by manual operation power hammering, owing to the size and Orientation of each hammer force is difficult to keep consistent, and
And apparatus structure is complicated when requiring the big hammering field of force to close, the actuation duration is also difficult to control to, therefore repeatable poor, it is difficult to motivate preferable power arteries and veins
Punching.
Summary of the invention
The invention provides a kind of automatic flexible power hammer, solved the stability of hammer force and repeatable demand, and overall structure is simple, manufactures
Process is easy.In mould measurement, provide bigger hammer force by flexible hammer handle, it is possible to online engineering goods are given size stabilising direction controlled
Excitation.
Above-mentioned automatic flexible power hammer is constituted by controlling and perform two parts, and control part is made up of motor, shaft coupling, actuated by cams axle and cam,
There is provided controlled power source for automatic flexible power hammer, control hammering process；Executable portion is made up of flexible hammer handle, returning spring, stand and tup,
As the execution unit of automatic flexible power hammer, under the drive of power source, complete hammering process.
Above-mentioned cam, is driven by actuated by cams axle, and actuated by cams axle connects transmission power by shaft coupling and stepping motor rotor.And cam is permissible
Employing different curvature changes, and drives hammer handle to form the swing of different acceleration magnitude, to adapt to different hammer force occasion.
Above-mentioned flexible hammer handle, the material of flexible hammer handle is spring steel plate, and hammer handle forms arcuation when hammering, uses tup and carrys out the acceleration increasing of resilience pendulum
Add the strength of hammering.
Above-mentioned tup, is connected as a single entity by locking nut and flexible hammer handle, and tup is mainly made up of the force transducer of replaceable hammer head material and top,
The tup changing unlike material has obtained the pumping signal of different-energy, hammer force size during force sensor measuring tup hammering.

The concrete schematic diagram of Fig. 1 automatic flexible power hammer.
In Fig. 1: 1. cam；2. flexible hammer handle；3. returning spring；4. stand；5. locking nut；6. power hammer hammer body；7. force transducer；8.
Replaceable hammer head material.
Detailed description of the invention
Illustrate further with instantiation below in conjunction with the accompanying drawings:
When energized, controlling rotor by pulse signal and rotate, when rotor rotates clockwise, rotor drives convex by shaft coupling
Rotating clockwise of wheel drive shaft, actuated by cams axle drives cam (1) to operate clockwise, and cam (1) rotates clockwise the flexible hammer handle (2) of drive
Around the upper rotating shaft swung downward of stand (4), returning spring (3) is gradually stretched, the power hammer on flexible hammer handle (2) top along with hammer handle (2) to
Lower swing completes hammering action.During hammering, the force transducer (7) between replaceable hammer head material (8) and power hammer hammer body (6) gathers hammer force size,
Signal is transported to computer in real time.Along with cam (1) is rotated further, flexible hammer handle (2) is upwards put under the elastic force effect of returning spring (3)
Dynamic, away from by hammering object.When rotor rotates counterclockwise, rotor drives rotating counterclockwise of actuated by cams axle by shaft coupling, and cam drives
Moving axis drives cam (1) to operate counterclockwise, and flexible hammer handle (2) is swung up, away from being tapped object under the effect of returning spring (3).
Along with cam (1) continues to rotate counterclockwise, drive flexible hammer handle (2) around the upper rotating shaft swung downward of stand (4), returning spring (3) gradually by
Stretching, the power hammer on flexible hammer handle (2) top completes downwards hammering action along with hammer handle (2).Force transducer (7) detection hammer force during hammering
Size, signal is transported to computer.
It has suffered the laminating that hammering process returning spring (3) is between the flexible hammer handle (2) of extended state holding and cam (1) all the time, it is ensured that hammer
Handle (2) can swing accordingly with the rotation of cam (1).Above-mentioned replaceable hammer head material (8) can be metallic aluminium matter tup, plastics
Tup, hard rubber tup or soft rubber tup, select unlike material according to different use occasions, being embodied as mentioned above of all material tups.
