Description
Technical field
The utility model relates to a kind of numerically-controlled cam grinder, control cam grainder that particularly can on-line automatic test master mold data.
Background technology
During workpiece such as China's tradition machining cam, all adopt imitative type method or manually grind and finish, what the quality of workpiece was all leaned on is that artificial working experience is controlled the emery wheel of rotation at a high speed or the feeding size and the angle of control workpiece guarantees; Yet the cam that processes according to the method described above because its synchronism and low precision, can directly cause the noise of weaving loom big, vibrations are big, rotating speed is low, also affect the quality and the output of fabric product simultaneously.
At present, also have and begin to come workpiece such as machining cam with Digit Control Machine Tool, but before workpiece processing, must measure by the engineer earlier, calculate cam master mold outer contour and obtain initial data, and need to measure the difference of calculating between itself and the master mold at each cam workpiece to be processed, could export the execution data then, process with Digit Control Machine Tool, so not only workload is big, inefficiency, and in process, all the time do not know the present situation of workpiece to be processed, more can not control,, the product percent of pass of being produced is descended greatly in case error occurs to process data.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of Numerical Control Cam lathe of on-line testing is provided, its collection on-line monitoring, online acquisition data, closed feedback is in one, simple in structure, easy to operate, the synchronism of the workpiece that processes is good, precision is high and controlled.
The on-line testing numerically-controlled cam grinder, comprise numerical control platform, support, workbench, servomotor, reductor, grinding carriage and bistrique, servomotor links to each other with cams mounted main shaft by reduction box, the top of main shaft is provided with online testing device, it comprises adjusting rod, displacement measurement instrument, said displacement measurement instrument is by support or directly hinged with adjusting rod one end, and it passes through the holding wire output and is connected with the numerical control platform.
Said displacement measurement instrument can be the striated pattern chi, and the lower end is provided with read head, and the striated pattern chi passes through support or directly is connected with adjusting rod, and read head vertically contacts surface of the work.
The displacement measurement instrument of being stated can be selected linear displacement transducer for use, and the lower end is provided with read head, and read head vertically is contacted with surface of the work.
Described displacement measurement instrument can adopt laser displacement sensor, and described laser displacement sensor is by support or directly be connected with adjusting rod, and its light source is light emitted to be contacted with surface of the work, and perpendicular to the tangent line of institute's contact-making surface.
In order further to improve precision, above-mentioned displacement measurement instrument is linear contact with contacting of surface of the work.
In the utility model, the displacement measurement instrument can be directly to workpiece master mold outer contour automatic data collection, generate the procedure desired data and be stored into system, and in process, can carry out online detection to workpiece by the displacement measurement instrument, feedback data is given system, at any time understand the processing situation of workpiece, and make in good time adjustment on the data automatically by system, realize precision control, precision control can reach ± 0.01 scope in; Simultaneously, the utility model is rational in infrastructure, is convenient to operation, and the synchronism of the workpiece that processes is good, precision is high.
Description of drawings
Fig. 1 is the utility model on-line testing numerically-controlled cam grinder structural representation.
Fig. 2 is displacement measurement instrument figure.
Among the above-mentioned figure: 1 is support, and 21 is reduction box, 2. servomotor, and 3 is adjusting rod, and 4 is the displacement measurement instrument, and 5 is read head, and 6 is cam, and 7 is holder, and 8 is holding wire, 9, sliding table, 11. grinding carriages, 12. bistriques.
The specific embodiment
As Fig. 1, shown in Figure 2: numerically-controlled cam grinder of the present utility model, contain numerical control platform, support platform 1, reduction box 21, adjusting rod 3, grinding carriage 11 and bistrique 12, servomotor 2 and tester 4, the cam (master mold or workpiece) 6 that the output shaft of servomotor 2 drives on the main shaft by reduction box 21; In the present embodiment; tester 4 is striated pattern chis; it can select models such as KA-300, KA-500, KA-900 for use; directly be fixed in reduction box 2 or be contained on the reduction box 2 by adjusting rod 3 by holder 7; the chi body of KA series striated pattern chi is connected with adjusting rod; read head contacts with cam 6 (master mold or workpiece) is linear; adjust the position of adjusting rod 3; make read head perpendicular to the surface of the work tangent line that is contacted; the output of its holding wire 8 is connected with the numerical control platform, with the displacement signal input numerical control platform of gathering.
The grating chi can be converted to pulse signal with the change in displacement of straight line, the corresponding distance that moves of the quantity of pulse signal, and pulse frequency has then been reacted movement velocity; For example adopt KA series striated pattern chi, it can be converted to displacement signal numeral or the pulse signal that computer can directly be gathered, and press industrial standard EIA one 442 one A output signals for feedback grating chi.
During operation, directly workpiece master mold outer contour is implemented image data by the grating chi earlier, generate procedure and be stored into system as normal data.The grating chi carries out online detection to workpiece then, and feedback data is given system, by system's control, makes comparative analysis with the master mold data again, and the output differential signal is realized precision control to servomotor, precision control can reach ± 0.01 scope in; It is rational in infrastructure, and is easy to operate, and the synchronism of the workpiece that processes is good, precision is high.
Described displacement measurement instrument also can be selected linear displacement transducer for use, laser displacement sensor etc., and such as linear displacement transducer LTS, linear displacement transducer PTS, linear displacement transducer FTS etc., buyable, its mounting means is similar.
When selecting laser displacement sensor for use, light that light source is penetrated must contact with surface of the work, and perpendicular to the tangent line of institute's contact-making surface.
