Abstract
The invention provides a rotatable abrasive disk having apertures permitting a view of a workpiece surface during the abrading process makes possible the incorporation of a condition sensing mechanism viewing the workpiece surface through the holes and capable of adapting the grinding conditions accordingly.
Description
Background of invention
The present invention relates to combining of field measurement apparatus and rotary abrasive tool.By to the operator or control milling tool lathe feed back in real time, can obtain this milling tool use and operate in major advantage.Significant main type of feedback in real time for example is a temperature, surface roughness, the location of workpiece or surface roughness in grinding, polishing and the fine finishining process.Up to now, these feed back in real time to depend on and use exper ienced operator or adopt the operation that is interrupted, and promptly more or less interrupt grinding continually and measure.Herein, term " grinding " speech should be understood that not only to refer to remove from the surface process of significant quantity material, and perhaps the more important thing is the process that is considered to fine finishining, polishing or smooth grinding.
Now invented rotary abrasive tool, it can be controlled from some key parameters of dynamic response and corresponding to the variation of these parameters by several different methods operation is regulated, and need not interrupt operation.
Summary of the invention
The invention provides a kind of rotary abrasive tool, this instrument comprises:
A) mill has the hole that penetrates this mill every a segment distance, is able to the surface is observed during making grinding operation,
B) rotating shaft that is driven by motor, described mill are installed on this axle; With
C) at least one noncontacting proximity sensor, the location of this sensor make and can pass through that those holes in the mill are observed and/or the situation on measuring workpieces surface when mill rotate.
Mill can be rigidity (promptly from supporting), but be that mill is bearing on the support pads usually more easily, this support pads has hole corresponding to the hole location place of institute's supporting mill on its pad, make can observe the workpiece that is grinding through mill and support pads when rotated.
Have that to observe the hole be that the mill of peep hole is known in the art, be used for making the operator to be able to when grinding is carried out evaluation by the surface appearance of lapped face.This class mill for example is described in WO/US96/19191.Yet the present invention has improved many again, adopts rotary abrasive tool, can not only observe surface of the work, and come the situation on measuring workpieces surface by using special method.
In one embodiment of the invention, noncontacting proximity sensor is a laser aid, is used for the surface smoothness of measuring workpieces and/or the distance between mill and surface of the work.Therefore in automation mechanized operation, this class sensor for example can advance mill with quick and controlled way to workpiece, with avoid postponing with because the too unexpected initial workpiece damage that causes that contacts.After starting was ground, laser can the monitoring workpiece surface, and controlled grinding pressure by appropriate feedback device, perhaps removed instrument when reaching suitable surface smoothness.A part that makes sensor become rotary abrasive tool can be guaranteed to spend the minimum time and carry out grinding operation effectively.
In another embodiment, noncontacting proximity sensor is to be used for the device of meter surface temperature specially, for example infrared sensing device.This device is even more important when pending surface is painted surface.For example, modern automobile lacker when being higher than uniform temperature (this temperature depends on the chemical property of polymeric matrix), tends to " balling-up " in process of lapping, i.e. partial melting or softening bead or the globule that forms polymer.This phenomenon can be destroyed the nonferromagnetic substance of mill certainly, and therefore the monitoring form surface temperature is very important during grinding.Temperature sensing device can separate use with above-mentioned laser sensing device, also may be incorporated in together, has so just obtained the surface appearance sensing device of dual mode.
Other noncontacting proximity sensor can respond light wave (ultraviolet light and visible light), sound wave and any other required various electromagnetic radiation.Be easily, have 3-6 hole on the mill, the position in these holes is identical from the radial distance of mill spindle.The size in hole should be enough big, guarantees that the surface appearance sensor can receive enough data when instrument uses to provide effective reading.The shape in hole is unimportant, but better is circular hole usually, because circular hole can provide maximum visibility under grinding condition, and the mill cohesion is destroyed minimum.Be preferably, the position of sensing device should be able to see through mill and observe in the radial position of mill largest hole area.
Because most important information just relates at polished surface of the work, so peephole better is that to be positioned at the footpath of mill outwards half side, because this is to use maximum places.Known in the mill of some form, removed sub-fraction on the mill periphery, so that can observe surface perpendicular to the mill edge.These peripheral parts that are removed equally also are considered to " hole ", because they are identical with the hole effect in the disk body, just are positioned at the diverse location of mill.
Sensing device is to transmit and/or receiving electromagnetic radiation carries out work by the hole in the mill, (kind of used electromagnetic radiation depend on will by the situation of sensing) as mentioned above.This means the rotating speed that will make monitoring system and mill and hole Frequency Synchronization in the practice through monitoring system.This just can guarantee that sensing device receives maximum information.
When mill was rigidity, situation for example was that mill is " a flap dish ", and wherein several apply that quadrangle tablet that grinding-materials make is connected on overlap mode that rigidity is generally on the disk of cup-shaped on one side with it and around a surface of this disk.This class mill need not support pads usually, is used for grinding off sealing wire or closing line.
The surface of mill can be a general type, combination by common structure coating (maker coat) and sizing menting property (size coat) is adhered to abrasive particle on the back lining materials, also can have and tie sizing menting property (supersizecoat), also can not tie sizing menting property to give special nonferromagnetic substance or feature.Yet mill also can have the surface of design shape, comprises little structure that duplicates, and as pyramid or the parallel spine that embarks on journey, each in them all is that the abrasive particle that is dispersed in the adhesive constitutes, and is bonded on the back lining materials.
At last, can comprise the material that one deck is made of the abrasive particle that is dispersed in the adhesive on the mill surface, its deposit on back lining materials becomes uniform layer or has the structure of certain contour surface.
Used abrasive particle can be any got material that is used for this purposes, can change in the scope of the diamond that is used for grinding specially purposes, CBN, cerium oxide, gama-alumina and crystallite Alpha-alumina being common to the aluminium oxide of field of milling, aluminium oxide-zirconium oxide, carborundum.
The adhesive component of mill can be selected from known adhesive in these purposes industries, comprise thermosetting resin, as phenolic resins, epoxy, the resin of radiation-hardenable is as acrylate, epoxy-acrylate, polyurethane-acrylate resin and similarly can be by visible light or ultraviolet light and electron beam radiation cured resin.Also comprise moisture cured resin.
The means that are used for driving the mill rotation can adopt any suitable motor apparatus, and whole milling tool can be contained in oblique grinder (angle grinder), offhand grinder (off-hand grinder), fixedly grinder (fixed grinder) etc. is top as an one basic element of character.
Better be, the situation sensing device is connected with control system on the instrument, and these control systems are regulated such as instruments with respect to parameters such as the position of workpiece, power that mill contacts with workpiece and speed of grinding plate.In addition, the situation sensing device can also be connected with means for signalling, and described means for signalling for example is lamp, clock or buzzer, is used for showing the terminal point or the limiting condition that have reached required.Obviously, if instrument uses with the offhand lapping mode, connection is preferably notice-type.
A preferable purposes of the present invention is at auto industry field, and the automation of wherein fine finishining process is very abundant.Rotary abrasive tool of the present invention is specially adapted to remove the lacquer painting defective when workpiece is the car panel of japanning.An example that is fit to the instrument of this purposes has two sensors: one is laser aid, be used for when workpiece is polished, reading its surface smoothness, and shut-down operation when reaching required fineness, another is a temperature sensor, and it is set for when surface temperature makes polishing during near temperature spot that paint polymer " balling-up " problem takes place and interrupts or slow down.Be used for having on the preferable mill of instrument the pattern of three circular holes, three orifice rings are around mill, and spacing equates, each hole all is positioned at from the mill center about 2/3 position to the circumference radial distance.The diameter in hole is about the 15-30% of mill radius.Lapped face purposes hereto is conventional, and is not crucial for instrument itself.
