The specific embodiment
For further understanding utility model content, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1,
A kind of screw pump rotor milling cutter knife sharpener, comprise base 1, be provided with length feed servomotor 2 and length feed guide rail 3 on base, vertically planker 4 passes through the length feed guide rails assembling on base, the vertical planker of length feed driven by servomotor carries out linear reciprocation and moves on base by the length feed guide rail, vertically on planker 4, traverse feed guide rail 5 is being installed, traverse feed servomotor 6 vertically also is installed and by the cross slide 8 of traverse feed driven by servomotor on planker, cross slide is provided with and swings transmission case 9, emery wheel wobble servo motor 11 is connected with the input that swings transmission case, the output that swings transmission case is provided with and swings planker 10, swing planker and be provided with the emery wheel rotating mechanism, the emery wheel rotating mechanism comprises emery wheel rotating servo motor 12, by the emery wheel 13 of emery wheel rotating servo motor driving with for emery wheel is installed, the grinding carriage of emery wheel rotating servo motor, also be provided with column 14 on base, column is provided with the cutter bracing frame 16 driven by cutter bracing frame lifting servomotor 15, cutter calibration servomotor 17 is installed on the cutter bracing frame and carries out the cutter indexing means 18 of calibration rotation by the cutter that makes of cutter calibration driven by servomotor.
The emery wheel actual size caused for the abrasion of grinding wheel solved in process changes, and affects the problem of machining accuracy.Preferably, can also swing planker and be provided with compensation of grinding wheel guide rail 19, by compensation of grinding wheel servomotor 20, be driven the emery wheel rotating mechanism moved back and forth swinging on planker by the compensation of grinding wheel guide rails assembling.
For, for convenience of accurately, the emery wheel that wearing and tearing occur is revised.Further preferred, also be provided with wheel dressing mechanism on column 14, wheel dressing mechanism comprises crushing cutter servomotor 21, the crushing cutter 22 rotated by crushing cutter driven by servomotor, and, for the crushing planker 23 of crushing cutter servomotor and crushing cutter is installed, the crushing planker is driven and is moved back and forth on column by upright guide rail 25 by crushing planker lifting servomotor 24.
The operating principle of this patent is:
The milling cutter body of needs processing is put on cutter indexing means 18, and installs and have good positioning.By 15 band cutter bracing frame 16 motions of cutter bracing frame lifting servomotor, put in place, cutter calibration servomotor 17 drives cutter indexing means 18 that the cutterhead calibration is rotated in place, length feed servomotor 2, traverse feed servomotor 6, cutter calibration servomotor 17,11 4 motor co-operatings of emery wheel wobble servo motor, drive emery wheel by emery wheel rotating servo motor 12 cutterhead 26 processed.After single cutter tooth process finishing on cutterhead, by cutter calibration servomotor 17 band cutter indexing means, be rotated calibration, process next cutter tooth.
There will be abrasion of grinding wheel in the time of due to processing, the actual size of emery wheel may diminish, so in the time of processing, can drive the emery wheel rotating mechanism by compensation of grinding wheel servomotor 20 is swinging on planker 10 by compensation of grinding wheel guide rail 19, carry out the contrary movement of the direction that diminishes with abrasion of grinding wheel, grinding wheel diameter, to make up the variation of grinding wheel diameter.Certainly, this compensation is seen, can complete by traverse feed servomotor and length feed servomotor, but the load of these two kinds of motors is large, power is larger, and in order to carry out the movement of this very small distance, it is good that the compensation of grinding wheel servomotor still is set separately.
After a cutterhead machines, because the machined surface of emery wheel can wear and tear, the shape of the machined surface of emery wheel and the shape of setting are not quite identical.So after cutterhead is removed, cutter bracing frame lifting servomotor 15 band cutter bracing frames 16 move down, space is got out of the way, by length feed servomotor, the acting in conjunction of traverse feed servomotor, emery wheel is moved to the wheel dressing mechanism place, drive crushing cutter 22 by crushing cutter servomotor 21 emery wheel is repaired, the machined surface of emery wheel is processed into to the shape of appointment.
Although the above is described the preferred embodiment of this patent by reference to the accompanying drawings; but this patent is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not breaking away from the scope situation that this patent aim and claim protect, can also make a lot of forms, within these all belong to the protection domain of this patent.
