Fig. 2 be polishing wheel according to the invention compensated measurement apparatus structure sketch map two;
Fig. 3 is the theory diagram of the compensating measurement method of polishing wheel according to the invention.
The specific embodiment
Below in conjunction with accompanying drawing concrete structure of the present invention is done further to describe.
After the polishing wheel wearing and tearing, the exposure level of workpiece and polishing wheel will descend to some extent, if program does not adjust, quality of finish must descend; If guarantee that quality of finish is constant, just must prolong polishing time, but this just involves the change to program, and so very uneconomical, lack operability; For this reason, the present invention adopts the wearing and tearing of polishing wheel is measured in real time, and it is fed back to main control system, through control program polishing wheel is compensated in real time.
Like Fig. 1, shown in 2; The compensated measurement device of polishing wheel according to the invention comprises: the contact wheel 5 that is in contact with one another with the polishing wheel 4 of polishing machine; And with the contact wheel 5 coaxial speed measuring motors that are connected 6; When contact wheel 5 contacted with polishing wheel 4 and rotate synchronously, contact wheel 5 drove speed measuring motor 6 and together rotates also output voltage, is used to detect the wear extent of polishing wheel; The signal output part of said speed measuring motor 6 is connected with the radio transmission module through the input voltage converter, is used for converting the wear extent of above-mentioned detection into voltage signal, and sends to main control system through the radio transmission module; The signal input part of said main control system is connected with the radio reception module through output voltage converter, is used to receive above-mentioned radiofrequency signal and obtains compensation rate with calculating, and through control program polishing wheel is compensated.
Why such scheme is able to implement, and is that numerical control polishing is a six-axis linkage: i.e. the rotation of mobile and U, V, the W axle of X, Y, Z axle.Above-mentioned six parameters of random time, optional position are having in one's pocket at main control system all.And in this programme, we the data that will obtain be exactly: under the current state, the effective position contacting of polishing wheel and contact wheel.Because the V axle of numerical control polishing can rotate continuously, and rotate the number of turns and do not limit, thus unsuitable cable laying between speed measuring motor and the main control system, so adopt the wireless transmission/reception module to realize the signal transmission between speed measuring motor and the main control system.
Above-mentioned contact wheel 5 is installed on the workbench 10 through threeway revolving bed 11, and workbench 10 is installed on the big base 8 through X base 9.Above-mentioned polishing wheel 4 is installed on the headstock 3, and headstock 3 is installed on the column 1 through crossbeam 2.Wherein, X base 9 moves in big base 8 upper edge X-directions, and workbench 10 moves in X base 9 upper edge Y directions, and crossbeam 2 moves in column 1 upper edge Z-direction; Threeway revolving bed 11 rotates around V, W axle, and the headstock 3 that polishing wheel 4 is housed rotates around the U axle.Requirement reaches: U axle align with the W axle (height such as axle center that are contact wheel and polishing wheel); The end face of polishing wheel 4 and contact wheel 5 is in the vertical plane; Again along the slow travelling table 10 of Y direction, when contact wheel 5 and polishing wheel 4 touch to a certain degree, contact wheel 5 can be driven to rotate.Contact wheel 5 is installed on the threeway revolving bed 11 through anchor clamps 7, and the rotating shaft of the rotating shaft of speed measuring motor 6 and contact wheel 5 is (being coaxial rotation) that fuse, thereby makes the main axis rotation and the output voltage of speed measuring motor 6.
As shown in Figure 3, the compensating measurement method of polishing wheel according to the invention is to utilize speed measuring motor 6 to measure the wear condition of polishing wheels through contact the contact wheel 5 that also rotates synchronously with polishing wheel 4, and said compensating measurement method comprises the steps:
(1) contact wheel 5 is suitably contacted with polishing wheel 4, and its running with polishing wheel is rotated synchronously;
(2) when polishing wheel 4 runnings, rotate with the contact wheel 5 coaxial speed measuring motors that are connected 6 thereupon, and produce metrical information;
(3) above-mentioned metrical information is sent to main control system with RF-wise through the radio transmission module after the conversion of the input voltage converter that is connected with speed measuring motor 6;
(4) main control system receives above-mentioned radiofrequency signal through the radio reception module, obtains metrical information through after the conversion of output voltage converter, and transfers to main control system;
(5) main control system writes down preservation simultaneously with above-mentioned metrical information and polishing machine Y axle parameter associated therewith, and contrasts with the metrical information that last time writes down, and calculates the polishing wheel wear extent of 4 the last times, promptly obtains the current compensation rate of polishing wheel;
(6) main control system is sent to the compensation rate feedback that aforementioned calculation obtains in the polishing program, and through the polishing machine control program polishing wheel is compensated, and the polishing wheel 4 and the exposure level of contact wheel 5 are remained unchanged, and keeps stable quality of finish.
As stated, use beginning from first time of polishing wheel 4, each location parameter of polishing machine that will be when keeping normally contacting between polishing wheel 4 and the contact wheel 5 carries out record, and compensates successively.And the permission wear extent of polishing wheel has the limit, that is to say, the summation of each time compensation rate also is limited, when the summation of compensation rate near or during the value of reaching capacity, main control system can send alarm signal, prompting operation person in time changes polishing wheel 4.Signal through speed measuring motor 6 collects is delivered to main control system through radio transmission and receiving system, and like this, Yi Bian be promptly to adopt promptly to send out, another side is promptly to receive i.e. usefulness, has saved the loaded down with trivial details of intermediate connection and line upkeep at ordinary times.
