Description
Technical field
The present invention relates to crushing technical field, in particular to a kind of grinding machine diamond abrasive wheel dressing device.
Background technique
In grinding process, the abrasive grain of grinding wheel is under friction, squeezing action, its corner angle gradually rounding rust, or
When grinding toughness material, usually caulked blocks grinding wheel surface, finally loses grinding wheel abrasive dust in the hole of wheel face
Lose cutting power.At this moment, slipping phenomenon can be generated between grinding wheel and workpiece, and may cause vibration and noise occur, make to grind
Efficiency decline is cut, surface roughness is deteriorated.Simultaneously because the increase of grinding force and grinding heat, can cause working deformation and influence mill
Precision is cut, can also make grinding skin occur burning and fine cracks when serious, so needing to modify grinding wheel.
At present for there are two types of the ways of diamond grinding wheel dressing: 1, skive together with crushing axis from equipment
On remove, on clamping to a dedicated equipment, remove finishing skive with the silicon carbide grinding wheel of rotation, skive repairs
It is whole it is good after skive is attached in equipment together with grinding wheel spindle again, more manual resource can be wasted in this way, finishing is caused to be imitated
Rate is low, and since secondary clamping has error, so that the product quality of processing not can guarantee.
2, a silicon carbide grinding wheel is installed in equipment, driving silicon carbide grinding wheel rotation is driven by belt using motor and is repaired
Whole skive, i.e., with the outer circle of the cylindrical finishing skive of silicon carbide grinding wheel, but this trimming device need compared with
Big installation space can not install the wheel dresser on all grinding machines, and such grinding wheel mounting device is mounted on
It after on grinding machine, can not remove, so that secondary device can only modify a grinding machine, cause the waste of resource.
The emery wheel grinding-head of both abrasive wheel trimming machines is water with skive position when carrying out diamond grinding wheel dressing
Flat setting, is difficult to modify the side of skive.
So needing a kind of grinding machine diamond abrasive wheel dressing device to solve the problems, such as this.
Summary of the invention
For above situation, for the defect for overcoming the prior art, the purpose of the present invention is just to provide a kind of grinding machine diamond
The problem of wheel dresser, effective solution skive is not easy finishing and existing trimming device waste of resource.
Its technical solution solved is that the present invention includes
Work box, work box left end are equipped with opening, and work box is interior there are two bistrique, and interior be equipped with of work box is adjustable two bistrique water
The grinding regulating device of flat left-right position, horizontal front-rear position and vertical upper and lower position;
Control cabinet, control cabinet are mounted on the right end of work box, are equipped with electric control system and numerical control device in control cabinet;
Fixed plate, fixed plate are equipped with and multiple can be fixedly connected respectively with work box or control cabinet and can adjust work box and control
The height controller of case height processed;
Supporting leg, supporting leg are mounted on height controller, and supporting leg lower end is equipped with universal wheel, and universal wheel, which is equipped with, to be fixed
Brake.
The invention has the benefit that when the skive on grinding machine needs to modify, it is no longer necessary to it is removed from equipment,
Trimming device only need to be moved to at skive and be fixed its position, start the silicon carbide grinding wheel of trimming device, it can be right
The outer circle of skive and end face are modified, and the restoring on line of skive is realized.Using the lesser grinding wheel of diameter
Bistrique, while passing through the revolving speed of the high emery wheel grinding-head of pneumatic lifting, so as to extremely readily realize to each face of skive
It is modified;Silicon carbide trimming stone is controlled using Pneumatic extension bar during the grinding process, pressure between bistrique and skive
When excessive, meeting nature stops, and avoids since polishing really up to the mark causes skive to damage, can be in finishing to diamond
Grinding wheel has stronger protection;And by adjusting the horizontal cross of bistrique, horizontal longitudinal and vertical position, sand can be made
The whole circumference for taking turns bistrique carries out reconditioning to skive, to realize to skive circumference, side and interior R's
Finishing;Currying work is controlled especially by control system every, trim amount, can also realize skive automatic trim, from
Dynamic compensation.Effectively raise processing efficiency.
