Disclosure of Invention

Technical problem to be solved by the invention

Patent document 1 describes a technique of pressing and dressing a dresser against a polishing surface of a rotating polishing wheel, and in this technique, the dresser pressed against the polishing surface of the polishing wheel needs to be replaced with a new one if wear occurs, but since the dresser is fastened to a holder, the replacement work requires time and effort, and is relatively inefficient.

In the dressing method of the present invention, the regulating body having a shape along the polishing surface is brought into contact with the polishing surface of the rotating polishing wheel over a desired length, and pressurized flowing water in which the abrasive grains are mixed is jetted between the polishing surface and the regulating body so as to pass through the polishing surface in the rotational direction with respect to the regulating body.

Further, the dressing apparatus of the present invention comprises: a regulating body having a surface having a shape corresponding to the shape of the polishing surface and contacting the surface to the polishing surface of the rotating polishing wheel in a desired length; means for generating a pressurized fluid mixed with abrasive particles; and a jetting device that jets the pressure fluid mixed with the abrasive grains toward a facing contact space between the abrasive surface and the regulating body.

Effects of the invention

According to the present invention, the rotating polishing surface is brought into contact with the regulating body along the shape of the polishing surface, and a fluid such as compressed air mixed with polishing particles is jetted in the rotation direction between the polishing surface and the regulating body and between the polishing surface and the narrow gap of the regulating body, so that the polishing particles are pressed widely and long against the polishing surface by the fluid pressure such as a compressed air flow, the regulation of the regulating body, and the rotation of the polishing wheel, and move at high speed while rolling, and therefore, a high-quality dressing can be performed.

Further, according to the present invention, since the polishing is performed by the limiter, the polishing can be performed with a small amount of abrasive grains.

Further, according to the present invention, the polishing head can be attached to the polishing head, and moved together with the polishing head, thereby performing polishing processing and dressing of the polishing surface.

The discharge port 15 is formed to have an average diameter of about 2mm, while the discharge port 15 is widened toward the outlet side 24 and the width of the polishing surface 6 is 5 mm.

The ejected abrasive grain generating device 11 is constituted by a mixed compressed air generator 37 using a vacuum generator including: a suction port 20 communicating with free abrasive particles in the abrasive particle container 7 via a tube 8; a supply port 22 for compressed air 21; and a discharge port 10 for discharging the compressed air 21 mixed with the free abrasive grains 9.

The front surface 25 of the regulating body 13 made of plastic resin such as bakelite has a length of 40mm to 60mm in a range from the inlet side 23 to the outlet side 24, and is concave in an arcuate shape along the grinding wheel 5.

On the front surface 25 of the regulating body 13, wall plates 26 having a cross-sectional shape of コ are formed vertically, and the pair of wall plates 26 sandwich the grinding wheel 5 to prevent the regulating body 13 from coming off the grinding wheel 5 and to prevent the jet-milled particles and the compressed air 21 from being blown out from between the grinding surface 6 and the ridge portion 12. In the intermediate region between the pair of wall plates 26 of the regulating body 13, a projected portion 12 is formed, the cross-sectional surface shape of the projected portion 12 and the top surface shape from the inlet side 23 to the outlet side 24 are formed in a shape along the grinding surface 6 of the grinding wheel 5, and a discharge port 15 for the compressed air mixed with the abrasive grains is opened near the inlet side 23 at the top 14 of the projected portion 12.

The ejection port 15 communicates with the ejected abrasive particle generating apparatus 11 via a communication path 16, a joint, and a pipe 17 in the restrictor 13.

The restricting body 13 is integrally provided with a mounting portion 31, and the restricting body 13 is held by the mounting portion 31 mounted to a cover holder 33 of the polishing head 32 via a pivot device 34 so as to be swingable horizontally forward and backward with respect to the polishing wheel 5.

As described above, the dressing apparatus 1 includes: a regulating body 13 having a surface of the protruding portion 12 having a shape corresponding to the shape of the polishing surface 6, the regulating body 13 being in contact with the polishing surface 6 of the rotating polishing wheel 5 over a desired length in an opposed manner; a discharged abrasive particle generating device 11, the discharged abrasive particle generating device 11 serving as a device for generating a pressure fluid in which abrasive particles are mixed; and a discharge port 15, the discharge port 15 serving as a jetting means for jetting compressed air mixed with abrasive grains, the jetting means jetting the mixed compressed air as a pressure fluid mixed with abrasive grains from the jetted abrasive grain generating means 11 toward a contact space between the polishing surface 6 and the surface of the projected portion 12 of the regulating body 13.

In the dressing apparatus 1, the regulating body 13 along the shape of the polishing surface 6 is brought into contact with the polishing surface 6 of the rotating polishing wheel over a desired length, pressurized air 21 containing abrasive grains is injected between the polishing surface 6 and the regulating body 13 and is passed through the polishing surface 6 in the rotational direction with respect to the regulating body 13, and the polishing surface 6 is dressed by maintaining the state of contact of the abrasive grains generated by the regulating body 13 with the injection force of the abrasive grains against the polishing surface 6 by the elastic force traction device 18 during the passage. The dressing apparatus 50 according to another specific example of the present invention shown in fig. 6 is an apparatus for mixing and discharging the abrasive grains 9 and the pressurized water 40, and the pressurized water 40 mixed with the abrasive grains 9 by the mixer 43 is sucked by the water pump 41, and the abrasive grain-mixed pressurized water 42 is pressure-fed from the water pump 41 to the discharge port 15 of the regulating body 13, and the abrasive grain-mixed pressurized water 42 is discharged from the discharge port 15 of the regulating body 13 toward the polishing surface 6.

In the dressing apparatus 50 shown in fig. 6, the regulating body 13 having the shape along the polishing surface 6 is brought into contact with the polishing surface 6 of the rotating polishing wheel 5 over a desired length, and the abrasive grain-mixed pressurized water 42 as pressurized flowing water in which abrasive grains are mixed is jetted between the polishing surface 6 and the regulating body 13 so as to pass through the polishing surface 6 in the rotational direction with respect to the regulating body 13, and during the passage, the elastic force traction device 18 maintains the jetting force of the abrasive grains generated by the regulating body 13 against the polishing surface 6 in a contact state, thereby dressing the polishing surface 6.
