Abstract
The utility model discloses a laser measurement device the bottom part of which is provided with a laser measurement head and a support for installing the laser measurement head, wherein the support is fixedly connected with a slide block capable of walking on a screw rod, and the screw rod is driven by a motor to rotate. The screw rod is rotated to realize the lifting of the laser measurement head. Under the condition of exceeding the measuring range, a section of compensation dosage of the laser measurement head is lifted, and the accurate measurement of data still can be realized. The laser measurement device has the advantages of simple structure, reliable control and low cost.
Description
Technical field
The utility model relates to the laser measuring device for measuring that is used to measure the curved plates surface coordinate in the water-fire heating plate bending machine.
Technical background
The numerical control water-fire heating plate bending machine is to utilize wire hot briquetting (line heat forming) principle, carries out steel plate processing.In the process, plate to be processed is divided into m * n coordinate point on X-axis and Y direction, with the profile Target Coordinate Data D of this m * n point
Mn(z) input computing machine then, is measured this m * n z value of putting pairing actual coordinate point on the steel plate by laser measurement system, generates one group of measurement data d for x, y
Mn(z), E must deviate for x, y
Mn(x, y, z)=F[D
Mn(x, y, z), d
Mn(x, y, z)], by fiery road expert system (a kind of fiery road software for calculation of water-fire heating plate bending machine commonly used) according to E
Mn(x, y z) calculate, and generate the fiery road diagram data L of flame forming plate
j[d
1(x, y), d
2(x, y)] and the flame forming plate parameter.Water-fire heating plate bending machine is controlled the rifle head of the flame gun of press brake automatically and is processed ship hull plate according to the fiery road figure that generates, thereby replaces the manual purpose that reaches the flame forming plate robotization.Laser measurement system is the very important part of above-mentioned numerical control water-fire heating plate bending machine, and the data of its measurement directly determine the processing fire road figure of final water-fire heating plate bending machine.To directly cause the ship hull plate precision of processing undesirable if deviation appears in measurement data, need anti-worker.Therefore, the numerical control water-fire heating plate bending machine need be selected high-precision laser measuring equipment, yet at present the range of laser measuring device for measuring is very limited, and the range of external advanced laser measuring equipment is mostly in 500mm, and the bigger price of range is very expensive.And the curvature of the ship hull plate that has is bigger, the fluctuating on himself surface just may near in addition surpass 500mm, the laser measuring device for measuring of feasible existing water-fire heating plate bending machine, meeting no to scale when measuring this class outside plate, make measuring error bigger than normal, even measure failure, bring adverse effect for the processing of ship hull plate.
Utility model type content
The utility model be intended to provide a kind of can be by regulating self height, with what adapt to above the DATA REASONING of range ability, and lower-cost laser measuring device for measuring.
Laser measuring device for measuring described in the utility model, the support that there is laser measuring head its bottom and is used to install laser measuring head connects firmly the slide block that can walk on screw mandrel on the support, and screw mandrel is by its rotation of motor-driven.
Laser measuring device for measuring of the present utility model, when the fluctuating of measurement steel plate is positioned at the range of laser measuring head, the airborne laser measuring device for measuring of flame forming plate moves horizontally, promptly when X-direction and Y direction moved, the lengthwise position of each point all was positioned at the range ability of laser measuring head on the steel plate, and measurement mechanism can be measured the Z axial coordinate of each point accurately, data computation with its measurement, draw the fiery road figure of processing, by the ship hull plate that fiery road figure processes, precision can be guaranteed.When the steel plate big rise and fall, when the drop that rises and falls exceeds the range ability of laser measuring head, move laser measuring head along X-direction and Y direction, there is the position that exceeds the laser measuring head range ability on the steel plate, when laser measuring head moved to these positions, the Z axial coordinate of its measurement point was greater than the maximal value of range or less than the minimum value of range, can rotate this moment by the motor-driven screw mandrel, slide block is moved up and down along screw mandrel, move up and down thereby the drive support carries laser measuring head.When the maximal value of the Z of measurement point axial coordinate greater than range, drive screw mandrel rotation drive laser measuring head and move down one section compensation rate, when the Z of measurement point axial coordinate during less than the minimum value of range, the reverse drive screw mandrel rotates to drive on the laser measuring head and moves one section compensation rate, thereby guarantee that measurement point is in the range ability of laser measuring head all the time, by increasing the distance that moves down on the basis of measured value or deducting the distance of moving, can measure the Z axial coordinate of measured point accurately, rise and guaranteed the precision of measuring, thereby guaranteed the accurate of flame forming plate machine work fire road figure, also promptly guaranteed the precision of bent plate processing.Described laser measuring device for measuring not only can adapt to above the range ability DATA REASONING, and simple in structure, cost is low.

Fig. 2 is a kind of side view of laser measuring device for measuring.
Embodiment
As shown in Figure 1 and Figure 2, a kind of laser measuring device for measuring, its laser measuring head 1 are loaded in the box 3 of support 2 bottoms, support is the tubulose of rectangle, be fixed on the slide block 4, slide block is threaded onto on the screw mandrel 5, matches with screw mandrel, can on screw mandrel, walk, the top of screw mandrel is equipped with motor 6, and motor shaft is by shaft joint 7 connecting filament masthead portions, and motor positive and inverse is moving can to pass to screw mandrel by shaft joint, thereby drive the positive and negative rotation of screw mandrel, the relative screw mandrel of slide block is walked up and down.Slide block can have two up and down, all fixes with support, and it can improve support with the stability of slide block when screw mandrel slides up and down.
Motor can be common electric machine, and time, the number of turns or range estimation by the control motor rotates make screw mandrel rotating band movable slider move up and down certain distance.Its requirement has relatively high expectations, needs operating personnel to control accurately to operating personnel, and is difficult for once accurately putting in place.
Motor also can be servomotor, can accurately control the rotation of servomotor by special Compensation Control, thus the compensation rate that accurate automatically control laser measuring head moves up and down.
Claims (3)
1. a laser measuring device for measuring has laser measuring head and the support that is used to install laser measuring head bottom it, and it is characterized in that: connect firmly the slide block that can walk on screw mandrel on the support, screw mandrel is by its rotation of motor-driven.
