Abstract

The utility model discloses a normal trimmer for a grinding wheel, which comprises servo motors and a gold pen, wherein the servo motor is connected with a ball screw by an elastic coupling to drive a lower trimming planker to make side-to-side motion; an arc trimmer is fixed on an upper trimming planker, and is driven by the servo motor to transmit a rotating shaft through an elastic coupling; a swing arm is fixed at the end of the rotating shaft; a gold pen holder is mounted in a hole of the swing arm in a clamping manner; the adjustable gold pen is mounted on the gold pen holder; the lower trimming planker is fixed on a sliding seat; and the upper trimming planker is fixed on the lower trimming planker. The normal direction trimmer adopts the three servo motors for linkage control, so that the surface of the trimmed grinding wheel is very smooth due to the fact that a point of the gold pen is contacted with the grinding wheel always, and the gold pen can perform trimming in a normal direction of the surface of the grinding wheel always.

Description

The grinding wheel normal trimmer

Technical field:

The utility model relates to a kind of grinding wheel normal trimmer, and particularly to the outer raceway (straight line, circular arc) of machining bearing, the grinding of outer raceway groove, internal diameter is specially adapted to the finishing of emery wheel orthodrome.

Background technology:

In the existing grinding, when wheel grinding after a period of time, the assorted bits that come off because of blunt and institute's grinder part of sand grains self have stopped up surperficial slit, cause emery wheel sharp inadequately, normally grinding, for the grinding capacity that recovers emery wheel or improve the quality of grinding workpiece, will trimming wheel, this just needs golden pen to repair the emery wheel of blunt, and the sand grains of surperficial blunt is come off.And with the effect quality that golden pen is repaired emery wheel, understand the quality that directly influence the grinding workpiece surface.Now the golden pen head of Shi Yonging is after amplification, it is not rule, but the regular shape that height differs, like this in the process of carrying out the circular arc finishing, when golden pen was in the difference of circular arc, the point that contacts with emery wheel was also different, because of golden pen head irregular, the small vestige that has caused the wheel face of repairing to form just to differ, thus the surface quality of grinding workpiece influenced.

Summary of the invention:

Task of the present utility model is to propose a kind ofly to guarantee that golden pen remains and the correction of wheel face normal direction, and the wheel face that was trimmed is smooth, makes the surface of grinding work piece obtain the raising of quality.

Task of the present utility model is finished like this, the grinding wheel normal trimmer, it comprises servomotor, golden pen, it is characterized in that: servomotor is connected the following finishing of driving planker by yielding coupling and does side-to-side movement with ball-screw, grinding wheel arc dresser is fixed on the finishing planker, and grinding wheel arc dresser is driven by the yielding coupling drive shaft by servomotor, and swing arm is fixed on the termination of rotating shaft, the gold pen-holder is snap-fit in the hole of swing arm, and adjustable golden pen is housed on the golden pen-holder.Under repair planker and be fixed on the slide, on repair planker and be fixed on down on the finishing planker.

The utlity model has following effect: the utility model adopts the servo interlock control of three covers, the emery wheel that repairs like this, cause is that a point of golden pen contacts with emery wheel all the time, so wheel face is very smooth, and guarantees that golden pen remains and the correction of wheel face normal direction.

Description of drawings:

Fig. 1 is structural representation of the present utility model; Fig. 2 is the upward view of Fig. 1.

Drawing explanation: 1-1, servomotor, 2, yielding coupling, 3, ball-screw, 4, repair planker down, 5, repair planker on, 6, grinding wheel arc dresser, 7, rotating shaft, 8, swing arm, 9, golden pen-holder, 10, golden pen, 1-2, servomotor, 1-3, servomotor.

The specific embodiment:

Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is by servomotor 1-1,1-2 and the servo interlock control of 1-3, guarantees that golden pen remains and the correction of wheel face normal direction.Servomotor 1-1 is connected the following finishing of driving planker 4 by yielding coupling 2 and does the left and right directions reciprocating motion with ball-screw 3, under repair planker and be fixed on move left and right on the lower slider, servomotor 1-3 is connected with ball-screw by yielding coupling, finishing planker 5 is done the fore-and-aft direction motion in the driving, last finishing planker slides before and after being fixed on down on the trimmer planker 4, grinding wheel arc dresser 6 is fixed on the finishing planker 5, grinding wheel arc dresser is driven by yielding coupling drive shaft 7 by servomotor 1-2, swing arm 8 is fixed on the termination of rotating shaft 7, gold pen-holder 9 is snap-fit in the hole of swing arm 8, on the gold pen-holder adjustable golden pen 10 is housed, when last, under repair planker 4,5 at servomotor 1-1, when motion made golden pen 10 walk out circular arc or curvilinear path mutually under the control of 1-3, grinding wheel arc dresser 6 guaranteed all the time that under servomotor 1-2 control golden pen keeps revising with the wheel face direction.

Claims

1. grinding wheel normal trimmer, it comprises servomotor, golden pen, it is characterized in that: servomotor is connected the following finishing of driving planker by yielding coupling and does side-to-side movement with ball-screw, grinding wheel arc dresser is fixed on the finishing planker, grinding wheel arc dresser is driven by the yielding coupling drive shaft by servomotor, swing arm is fixed on the termination of rotating shaft, and golden pen-holder is snap-fit in the hole of swing arm, and adjustable golden pen is housed on the golden pen-holder.
