Whole device, linear rolling track are fixed on angle fine-adjustment mechanism, and angle fine-adjustment mechanism is fixed on bistrique clamping seat, angle adjustment
Mechanism is connected between linear rolling track and bistrique clamping seat and controls angle between the two, and angle fine-adjustment mechanism side is set
Angled fine tuning retaining mechanism.
Further, the motor of electro spindle is integrated with main shaft, frequency control, maximum speed 24000r/min, function
Rate is 2.5kW, rotating accuracy 0.005mm.
Further, the material of grinding wheel is white fused alumina, and diameter 20mm, grinding method is dry grinding.
Further, the precision of linear rolling track is 0.02mm.
Further, dresser is diamond pen.
Further, angle fine-adjustment mechanism is made of a pair of of worm and wormwheel and clamping device.
The beneficial effects of the utility model are: using high-speed electric main shaft, feed mechanism is rolled using high-precision straight line

Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
A kind of roll centre hole processing device as shown in Figure 1, including electro spindle 1, grinding wheel 2, linear rolling track 3, angle
Degree micro-adjusting mechanism 4 and bistrique clamping seat 5, grinding wheel 2 are installed on the end of electro spindle 1, and linear rolling track 3 is fixed on electro spindle 1
Side simultaneously controls its displacement, and the side of linear rolling track 3 is equipped with the dresser 6 of face grinding wheel 2, linear rolling track 3
It is fixed on angle fine-adjustment mechanism 4, angle fine-adjustment mechanism 4 is fixed on bistrique clamping seat 5, and angle fine-adjustment mechanism 4 is connected to directly
Between the line rolling guide 3 and bistrique clamping seat 5 and angle of control between the two, 4 side of angle fine-adjustment mechanism is micro- equipped with angle
Adjust retaining mechanism 7.
The motor of electro spindle 1 is integrated with main shaft, frequency control, maximum speed 24000r/min, and power is
2.5kW, rotating accuracy 0.005mm.
The material of grinding wheel 2 is white fused alumina, and diameter 20mm, grinding method is dry grinding.
The precision of linear rolling track 3 is 0.02mm.
Dresser 6 is diamond pen.The wheel face abrasive grain modified in this way is sharp, grinding performance is good, sand
The wheel service life is long, can obtain very high machining accuracy and lower surface roughness value.
Angle fine-adjustment mechanism 4 is made of a pair of of worm and wormwheel and clamping device.Hand rotary worm can realize angle adjustment
Function.
Start electro spindle turn up 20000r/min, adjustment dresser makes it contact grinding wheel side bus, makes grinding wheel side
Bus is modified on trimmer.Rotational angle micro-adjusting mechanism is attached to grinding wheel side bus accurately on roll centre hole surface later,
Turning of work piece and the advance of slow rotation hand feed electro spindle, make grinding wheel move realization centre bore along centre hole side bus straight line
Surface grinding.After with template inspection, if angle and surface quality do not reach requirement, adjust the angle micro-adjusting mechanism and try again
Grinding is until up to requiring.
The surface quality and angle precision of grinding center boring ratio articulation centre bore are greatly improved, and eliminate centre bore table
Face tool marks, ripple, hence it is evident that the positioning accuracy for improving lower road grinding process is reprocessed without artificial porting, improved work efficiency.
In grinding process, the cutting edge of grinding wheel under the impact of grinding force and grinding heat, occur abrasive grain it is micro- broken and compared with
Big is broken, and forms new cutting edge and Grain Falling Off, so that new abrasive grain is participated in grinding, this is that other cutting process are no
Unique features can obtain very high machining accuracy and ideal surface roughness, be to improve roll centre hole surface processing matter
Measure main process.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
