Abstract
The invention discloses a grinder with a laser distance automatic compensating device, which relates to a common control or adjusting system characterized by a compensating control device of error, load and inertia caused by clearances, over correction, tool deviation, tool abrasion, temperature and machines, and the like, and a functional unit of the system and a monitoring or testing device of the system or the unit. The grinder comprises a work bench (1) and a grinding wheel (2); a laser probe (3) is vertically fixed under the grinding wheel (2) and internally provided with a laser receiving device; a feeding mechanism of the grinding wheel (2) is connected with a controller and a servo mechanism (4); the controller is internally provided with a memory which stores the standard value of distance. The grinder obviously improves the precision of work pieces to be processed, has good uniformity, achieves process requirements and improves the utilization rate of the grinding wheel.
Description
Technical field
The control device that the present invention relates to compensation is a feature, for example for the functional unit of the general control of gap, toning, tool offset, tool wear, temperature, machine construction error, load, inertia or regulating system and this system be used for the supervision or the testing arrangement of this system or unit, be specially a kind of grinding machine that has laser ranging system.
Background technology
Grinding machine at work, plane of grinding wheel contacts grinding with workpiece, thereby reaches the purpose that workpiece is worked into preliminary dimension.In general production and processing, be the process of a mutual grinding because flat-faced wheel is processed with workpiece, when workpiece was ground, plane of grinding wheel also can loss, and the amount that only is ground is a little bit smaller.But, because the loss of emery wheel can have direct precision influence to the size of workpiece to be machined, we can say the wear extent of emery wheel, caused the error of workpiece size.Key is if there is a kind of method can detect the wear extent of emery wheel at any time, makes compensation at this wear extent, and workpiece accuracy has just had guarantee so.What tradition adopted in the past is the tubule air-jet method, so-called jet ratio juris is jet facing to emery wheel with a thin pipe, the distance of tube mouth and emery wheel is very near, about 1mm is wearing sensing device behind the pipe, utilize jet reflectivity, drive sensor, thereby this signal input controller, send the adjustment signal, reach compensating action by controller.But this device defectiveness, the one, because shower nozzle exchange premium emery wheel, can be by abrasion of grinding wheel, it is big that spout becomes, thus the chap of ejection air-flow, the reflection precision reduces, moreover be open loop control, shower nozzle can't be known by the grinding accuracy of emery wheel, causes control accuracy uncertain, final products precision instability, error is big.
Summary of the invention
In order to overcome the defective of prior art, thereby provide a kind of control device precision height, grinding machine that the machining accuracy that is quick on the draw is high, the invention discloses a kind of grinding machine that has laser ranging automatic compensation device.
The present invention reaches goal of the invention by following technical solution:
A kind of grinding machine that has laser ranging system comprises workbench and emery wheel, and it is characterized in that: vertical fixing has laser probe under the emery wheel, includes laser receiver in the laser probe; Be connected with controller in the feed mechanism of emery wheel and wait upon clothes mechanism, memory is arranged in the controller, store memory contains the standard value of distance.
The grinding machine of described laser ranging system is characterized in that, its operation wavelength of laser probe emitted laser is 905 nanometers, the operating frequency during detection between 1～9000 time/second, apart from emery wheel apart from the 800mm scope.
Operation principle of the present invention is:
Laser ranging is to use the pulse ratio juris, the laser that sends is received by range finder again after the reflection of object being measured, and range unit is the round time of recording laser simultaneously, half of the product of the light velocity and two-way time is exactly the distance between distance mearuring equipment and the object being measured.Operation wavelength is 905 nanometers, and it is adjustable between 800mm to find range, and precision belongs to high-resolution instrument within 5 μ m.
At first by specially treated laser probe be vertically fixed on revolving wheel under, when work is carried out, allow laser send a branch of smooth directive emery wheel earlier, and the tieback of turning back closes up, measure the destination distance by receiving system by calculating, this distance is stored in the memory module as standard value, owing to be engraved in operation during the grinding of emery wheel and workpiece, laser ranging is carried out detection (detection frequency of the present invention can be adjustable from 1～9000 time/second) in real time with the frequency of per second 500 times.The distance that detects is in real time made comparisons with the gauged distance in the memory, if difference is arranged, controller sends instruction and does corresponding the adjustment, thereby reaches the purpose of eliminating difference.
The present invention has used the laser ranging control mode, makes the precision of workpiece to be machined significantly improve, and high conformity reaches the requirement of technology, and the utilization rate of emery wheel is improved.
By using laser ranging from this technology, fundamentally solved the deficiency that traditional in the past jet distance measuring method brings, use closed-loop control because be, compare with open loop control, measure feedback fast, the accurate efficient height of control accuracy, advantages such as shower nozzle is never wornout, and is easy to use.
