Abstract
A kind of mould measurement device based on motion control, it is to generate three-axis moving by computer motion control, reaches automatic trigger capacitive proximity switch after measuring point, and closing of circuit moves downward electromagnet, and drive hammer completes a beat, until having struck all measuring points.The device is easy to operate automatic, is suitable for the high-precision modal test of various structures.
Description
Technical field:
The present invention relates to a kind of mould measurement device, specifically a kind of mould measurement device based on motion control.
Background technique:
Modal test is widely used in many engineering structures such as machinery, building, Aeronautics and Astronautics, is tried by mode
Test the kinetic parameters such as intrinsic frequency possessed by available structure, the vibration shape, damping.Common modal test using power hammer into shape into
Result can be calculated using model analysis software by acquisition exciting force and acceleration responsive signal in row exciting.But this
That there are positioning accuracies is poor when measuring point is numerous for kind of test, and hammer force is excessive or too small or even has double hit phenomenon, these can all be caused
Test error influences the accurate analysis to structure.When measuring point has one or two hundred, artificial tap needs first to write mark to measuring point
Note is tapped by point one by one, is run out of space to testing crew.To solve this problem, patent CN105716816 proposes one kind
Modal test device based on line slide rail and electromagnetic coil, but be used for a panel region measuring point when, need constantly to change device position
It sets, the primary measuring point solved on straight line is then unable to test if measuring point is distributed on circumference or other curve shapes.
Summary of the invention:
The purpose of the present invention is to solve the shortcomings of the prior art and providing a kind of mould measurement dress based on motion control
It sets.The device, which is adopted to computerized control, carries out multiaxial motion, and measurement accuracy is high, and high degree of automation is easy to operate.
Technical solution of the present invention:
Measured structure part is fixed below this mould measurement device, computer controls motion control card, transports tri- axis of XYZ
Move point position, Z axis in place after, capacitive proximity switch automatic trigger, close the switch circuit make electromagnet generate downwards fortune
Dynamic, drive hammer taps measuring point, computer acquisition exciting force and acceleration responsive signal, completes the mould measurement of a bit, then
This process is repeated, until all measuring points have been tested, end is tested.
Further, the capacitive proximity switch is changed to inductance, photoelectric proximity switch.
Further, the motion control card is general motion control apparatus, is not needed individually designed.
The beneficial effects of the present invention are: compared with the prior art, the present invention is a kind of mould measurement based on motion control
Device, measurement accuracy is high, and high degree of automation is easy to operate.
Detailed description of the invention:
Fig. 1 is structural schematic diagram of the invention.
Marked in the figure: 1 X-axis, 2 Y-axis, 3 Z axis, 4 capacitive proximity switches, 5 electromagnet, 6 power hammer, 7 motion control cards, 8
Computer.
Specific embodiment:
As shown in Figure 1, a kind of mould measurement device based on motion control.Including 1X axis, 2Y axis, 3Z axis, 4 capacitors are close
Switch, 5 electromagnet, 6 power hammer, 7 motion control cards, 8 computers.
Measured structure part is fixed below this mould measurement device, computer 8 controls motion control card 7, makes X-axis 1, Y
Axis 2, Z axis 3 move to point position, Z axis 3 in place after, capacitive proximity switch 4 trigger, close the switch circuit make electromagnet 5 produce
Life moves downward, and drive hammer 6 taps measuring point, and computer 8 acquires exciting force and acceleration responsive signal, completes the mode of a bit
Test, then repeats this process, and until all measuring points have been tested, end is tested.
The mould measurement device working principle based on motion control is: motion control card makes under the control of the computer
XYZ three-axis moving to point position, in place after trigger capacitive proximity switch automatically, transport electromagnet downwards by closing of circuit
Dynamic, drive hammer completes a beat, until having struck all measuring points, computer-automatic collection mode signals.
