Description
Technical field
The utility model relates to the grinding special-purpose machinery, is a kind of steam turbine axle journal grinding attachment specifically.
Background technology
The bearing both sides of steam turbine and axle and gear-box in conjunction with the end gear piece formula oil scraper ring is set mostly, be used for sealing to lubricating oil, keep off oily gear piece usually and spool be arranged to fit clearance.Because turbine shaft is an ellipse from static movement locus to its axle journal of running status, add turbine shaft be in operation self vibration and gap, certainly will keep off contacting of oily gear piece and axle journal, and cause the damage by friction of axle journal.The axle journal of damaged needs to repair, the reparation of not rolling off the production line of steam turbine axle journal at present generally adopts the method for various spraying coating process and metallic brush plating to be equipped with the hand scraping finishing, because the various specification requirements that the finishing of the method for the hand scraping axle journal after to spray treatment is difficult to recover axle journal, as circularity, beat, fineness etc., its finishing effect is undesirable.In addition, because hand scraping reparation work efficiency is low, repair long in time limit.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of online quick reparation that realizes is provided, and repairs the high steam turbine axle journal grinding attachment of precision.
The technical scheme that realizes above-mentioned purpose is: a kind of steam turbine axle journal grinding attachment, it has the support that top is provided with horizontal guide rail, on horizontal guide rail, be equipped with the horizontal slip body, be fixedly connected with inclined guide rails with the horizontal slip body, on inclined guide rails, be equipped with the sliding motor frame, the front end of motor frame is equipped with motor, and motor shaft end is equipped with grinding wheel; Be respectively equipped with level pulling leading screw and the pulling leading screw that tilts with horizontal slip body phase configuration and on inclined guide rails with sliding motor frame phase configuration on the horizontal guide rail, and the leading screw handwheel of configuration dial is being installed on leading screw respectively.
The technical solution of the utility model also comprises: the inclination angle of described inclined guide rails is 45 °.
The utility model adopts electric wheel to the reparation of wearing and tearing of the axle journal of steam turbine, and by accurate Control Shaft to the cooperating of the rotation of the guide rail of radial feed, slide block, screw mechanism and the turbine shaft of finishing by the steam turbine electric barring equipment, realize the reconditioning of not rolling off the production line of turbine shaft.It is simple to have apparatus structure, easy to use, grinding efficiency height, the characteristics that the axle journal repairing effect is good.
Description of drawings
Accompanying drawing is this steam turbine axle journal grinding attachment structural front view.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
Provide as accompanying drawing, this axle journal grinding attachment has the support 1 that a top is provided with horizontal guide rail 2, on horizontal guide rail 2, be equipped with horizontal slip body 3, be fixedly linked with horizontal slip body 3 and be connected to inclined guide rails 8, on inclined guide rails 8, be equipped with sliding motor frame 9, the front end face of motor frame 9 is installed with motor 10, and the axle head of motor 10 is equipped with abrasive grinding wheel sheet 11; On horizontal guide rail 2, spur leading screw 4 with the coaxial level that is equipped with of guide rail, and the feed screw nut that disposes on leading screw connects horizontal slip body 3, on inclined guide rails 8, tilt to spur leading screw 7 with coaxial being equipped with of guide rail, and the feed screw nut that disposes on leading screw connects sliding motor frame 9, front end at level pulling leading screw 4 is equipped with the leading screw handwheel 5 that disposes dial, and the leading screw handwheel 6 of configuration dial is installed at the front end of the pulling leading screw 7 that tilts.
When the utility model was used for the axle journal grinding, its abrasive grinding wheel sheet contacted with axle journal to be ground is radially tangent, when grinding wheel rotates at a high speed, utilized the electric barring equipment of steam turbine that axle journal is rotated, and can implement the reparation of grinding axle journal.The width of its axle journal grinding moves back and forth by level pulling leading screw pulling horizontal slip body and realizes, the radially forward and back of the relative axle journal of abrasive grinding wheel is finished by the pulling leading screw that tilts, and by be assemblied on the leading screw handwheel the dial Control Shaft to radially the amount of feeding.
When the utility model is specifically implemented, can be used for accurately controlling grinding in that the electron amount measurement mechanism is installed between horizontal guide rail and the horizontal slip body and between inclined guide rails and the sliding motor frame to axle journal.
As accompanying drawing embodiment, preferred 45 ° of the inclination angle of the utility model inclined guide rails 8.The contact point that is about to abrasive grinding wheel sheet and axle journal is arranged on and axle journal radial level center line angle at 45 position, make the advance and retreat cutter motion of emery wheel become function movement locus, show show value maintenance corresponding relation on the chi with the practical grinding amount and the depth of cut of guaranteeing emery wheel at axle journal Y-Z axial plane and Y=Z.
The level pulling leading screw of this device can assemble electric driver mechanism, to realize the self-acting feed of grinding horizontal direction.
This device can be installed in the grinding of implementing on the general lathe the axle cylindrical.
