Description

Screw pump rotor milling cutter blade grinder trimming device

Technical field

This patent belongs to the processing technique field of screw pump rotor, particularly relates to a kind of screw pump rotor milling cutter blade grinder trimming device.

Background technology

At present, the molded line of the rotor of screw pump is the method processing that adopts milling mostly, and the machining accuracy of Milling Process depends on the precision of milling cutter body to a great extent.At present use a period of time to wear and tear when milling cutter body, when need to again whet a knife, and milling cutter be to adopt emery wheel to carry out the reconditioning cutterhead, but wearing and tearing also can occur in emery wheel simultaneously when whetting a knife, and is also to need repair.Once need trimming wheel, emery wheel will again take off from lathe, need secondary to be installed, and this has just destroyed original installation accuracy be installed, thereby has reduced machining accuracy.Especially for numerical-control screw rod pump rotor milling cutter knife sharpener, repeatedly being installed of emery wheel, the precision advantage of almost Numeric Control Technology being brought is offset fully.

Summary of the invention

This patent provides a kind of screw pump rotor milling cutter blade grinder trimming device for solving the technical problem existed in known technology, during this trimming device finishing without pulling down emery wheel, the problem of having avoided the emery wheel secondary to be installed.

A kind of screw pump rotor milling cutter blade grinder trimming device, comprise base, it is characterized in that: be provided with length feed servomotor and length feed guide rail on base, vertically planker passes through the length feed guide rails assembling on base, the traverse feed guide rails assembling is on vertical planker, the traverse feed servomotor vertically is installed and by the cross slide of traverse feed driven by servomotor on planker, cross slide is provided with the emery wheel rotating mechanism, the emery wheel rotating mechanism comprises emery wheel rotating servo motor and the emery wheel driven by the emery wheel rotating servo motor

Also be provided with column on base, also be provided with wheel dressing mechanism on described column, wheel dressing mechanism comprises crushing cutter servomotor, the crushing cutter rotated by crushing cutter driven by servomotor, and, for the crushing planker of crushing cutter servomotor and crushing cutter is installed, described crushing planker is moved back and forth by upright guide rail by crushing planker lifting driven by servomotor on column.

Advantage and good effect that this patent has are:

Because this patent adopts technique scheme, utilize crushing cutter servomotor to drive the emery wheel rotation, utilize crushing cutter servomotor to drive the emery wheel rotation, the two does the rotation of the direction that communicates, make between emery wheel and crushing cutter grinding occurs, the emery wheel that wearing and tearing occur is polished again.This patent can directly be polished the emery wheel be arranged on knife sharpener to put in place, without emery wheel is pulled down to polishing, reinstalls again, has eliminated error when emery wheel is repeatedly installed; Improve the machining accuracy of screw pump rotor milling cutter, thereby finally improved the machining accuracy of screw pump rotor, improved the operational efficiency of screw pump.

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 blade grinder trimming device, comprise base 1, be provided with length feed servomotor and 2 length feed guide rails 3 on base, vertically planker 4 passes through the length feed guide rails assembling on base, traverse feed guide rail 5 is arranged on vertical planker, traverse feed servomotor 6 vertically is installed and by the cross slide 7 of traverse feed driven by servomotor on planker, cross slide is provided with the emery wheel rotating mechanism, the emery wheel rotating mechanism comprises emery wheel rotating servo motor 8 and the emery wheel 9 driven by the emery wheel rotating servo motor

Also be provided with column 10 on base, also be provided with wheel dressing mechanism on column, wheel dressing mechanism comprises crushing cutter servomotor 11, the crushing cutter 12 rotated by crushing cutter driven by servomotor, crushing cutter servomotor and crushing cutter are installed and are installed in crushing planker 13, the crushing planker is driven by crushing planker lifting servomotor 14, and is moved back and forth on column by upright guide rail 15.

The operating principle of this patent is:

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 band cutter bracing frame moves down, space is got out of the way, by length feed servomotor 2,6 actings in conjunction of traverse feed servomotor, emery wheel is moved to the wheel dressing mechanism place, by crushing cutter servomotor 11, drive 12 rotations of crushing cutter, crushing cutter servomotor drives the emery wheel rotation, emery wheel is repaired, thereby 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.
