Abstract
The utility model relates to a laser section profile detector which is characterized in that a motor is connected with a screw rod; the screw rod is thread-connected with a nut; the nut is connected with a lifting rod; the lifting rod is connected with a measuring instrument; the measuring instrument is provided with a small guide rail; the small guide rail is connected with a small guide rail slide block in a slide way; the small guide rail slide block is connected with a measuring rod; a laser distance measuring sensor is arranged above the measuring rod; a pressure spring is arranged between the measuring rod and the measuring instrument. During measurement, the measuring rod is pressed on a work piece to be detected with appropriate pressure by the pressure spring, which can avoid the impact of complicated and changeable surface conditions of the work piece, such as scale cinder, anti-rust paint, water and other impurities, etc. on the non-contact laser direct measurement. Therefore, the utility model has the advantages of high measurement precision and good stability.
Description
Technical field:
The utility model relates to a kind of laser profile pick-up unit, is specifically related to a kind of laser profile pick-up unit that detects bent plate profile height value in numerical control bent plate forming machine.
Background technology:
In existing shipbuilding process, the curve generating of ship plank generally adopts the flame forming plate technology of traditional experience that depends on, and production efficiency is low, and forming accuracy is poor, and work under bad environment, its profile detect and adopt " sample case " or " model " to carry out." sample case " worker duration, the cost height.
Japan, Korea S and domestic indivedual cartel universities and colleges Preliminary development go out to be used for the equipment that bent plate is shaped, and its measurement mechanism be two kinds of the direct measurements of contact type measurement and laser substantially.But these two kinds of the former precision of metering system are low, and poor stability is subjected to surface of the work situation and measurement environment to influence greatly the cost height when latter measures.
Summary of the invention:
The purpose of this utility model is to design a kind of laser profile pick-up unit, to improve measuring accuracy and stability, reduces the influence to measuring of surface of the work situation and measurement environment as far as possible.
To achieve these goals, the technical solution of the utility model is as follows: a kind of laser profile pick-up unit comprises base, base is provided with motor, it is characterized in that motor is connected with leading screw, leading screw is connected with nut thread, and nut is connected with elevating lever, elevating lever is connected with measuring seat, measuring seat is provided with little guide rail, and little guide rail and little guide rail slide block are slidingly connected, and little guide rail slide block is connected with sounding rod, the sounding rod top is provided with laser range sensor, is provided with stage clip between sounding rod and the measuring seat.According to an embodiment of the present utility model, nut is connected with the guide rail slide block, and guide rail slide block and guide rail are slidingly connected, and guide rail is fixedlyed connected with base.Little guide rail slide block is provided with sensing chip, and little guide rail slide block top is provided with upper level sensor and following level sensor, and little guide rail slide block below is provided with positive stop.The top of sounding rod is provided with laser-bounce face, and measuring seat is provided with the sunscreen protection cover.
When described pick-up unit is worked, servomotor or step motor drive elevating lever band sounding rod and are descended, the sounding rod contact workpiece and be hampered by workpiece after the relative measurement seat is moved upward, the next sensor-triggered on it, controller control elevating lever stops to descend.Controller reads its distance that descends with respect to the distance at sounding rod rear portion and servomotor or step motor drive elevating lever relative measurement zero-bit that is fixed on that the laser range sensor on the measuring seat records respectively then, with two distances and the addition of pick-up unit comprehensive mechanical constant, get final product the bent plate profile height value of inspection positions.During measurement, above-mentioned sounding rod is pressed on the workpiece for measurement with suitable pressure under the effect of stage clip, can avoid complicated, and changeable surface of the work situation is as oxide skin, rust protection paint, the influence that water and other foreign material etc. are directly measured non-contact laser; The laser-bounce surface state at test rod top is stablized (but laser reflector of installation code), and there is the sunscreen protection cover measuring seat outside, can make each measurement state consistency, avoids the influence of environment spurious rays; Select the laser range sensor that measurement range is little, precision is high for use, reduce cost, improve measuring accuracy.Therefore, advantage of the present utility model is measuring accuracy height, good stability.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated.
A kind of laser profile pick-up unit, as Fig. 1, base 3 is installed on the X, Y travel mechanism 14 of numerical control bent plate forming machine, the servomotor or the stepper motor 1 that are installed in base 3 tops drive leading screw 8 rotations by speed reduction unit 2, nut 10 on the leading screw 8 is done corresponding elevating movement by guide rail slide block 11 along guide rail 6 under the transmission of leading screw 8, thereby drive elevating lever 13 1 liftings that are installed in nut 10 bottoms, the range of elevating lever 13 is 1200mm, and maximal rate is 6000mm/min.
When illustrated pick-up unit is worked, after the X of numerical control bent plate forming machine, Y travel mechanism 14 are being with pick-up unit to move to the detection position, controller control servomotor or stepper motor 1 driving elevating lever 13 by numerical control bent plate forming machine are being with sounding rod 27 to begin to descend by detecting zero-bit, sounding rod 27 contact workpieces and be hampered by workpiece after relative measurement seat 16 is moved upward, following level sensor 21 on it triggers, and controller control elevating lever 13 stops to descend.When the increase of tested position height, when upwards jack-up sounding rod 27 arrived upper level sensor 20 trigger positions, controller control elevating lever 13 rose and stops output signal up to upper level sensor 20.Then controller read respectively that the laser range sensor 17 that is fixed on the measuring seat 16 records its drive the distance that elevating lever 13 relative measurement zero-bits descend with respect to the distance at sounding rod 27 rear portions and servomotor or stepper motor 1, with two distances and the addition of pick-up unit comprehensive mechanical constant, can get the bent plate profile height of inspection positions.After recording data, the controller of numerical control bent plate forming machine control servomotor or stepper motor 1 drive elevating lever 13 and are being with sounding rod 27 to rise, and get back to the detection zero-bit.
The utility model mainly is to adopt laser range sensor to record its distance with respect to sounding rod top lasers reflecting surface, and controller writes down and provide the distance of servomotor or the decline of step motor drive elevating lever relative measurement zero-bit.The scope that the diagram pick-up unit is measured bent plate shape face height is 0～1200mm, and measuring accuracy is ± 0.03mm.
