Description

  The present invention relates to a polishing tool of a polishing machine that is detachably mounted on a polishing machine that polishes an object to be ground into a required shape by reciprocating an abrasive material. The present invention relates to a polishing tool suitable for surface repair of various metal parts.

  In the work of polishing a polishing body in a required shape in a conventional automobile repair, a hook-and-loop fastener (Velcro Magic (registered trademark)) is used by bonding, screwing, or the like to a flat abrasive holding plate having no elasticity. Polishing in which the other surface fastener to which the abrasive is bonded (in this case, the engaged side) is attached by pressure contact to the abrasive holder to which Malt Magic (registered trademark) is attached. The machine polished all curved surfaces, uneven surfaces, etc.

  However, in the case where the thickness is 2.07 to 2.14 mm with Velcro Magic (registered trademark) on the pressure contact surface such as the hook-and-loop fastener between the abrasive material holding body and the abrasive material, when the required pressure is applied, the contraction length Is 1 mm or more. In addition, when the thickness of Malt Magic (registered trademark) is 1.20 to 1.23 mm, when a required pressure is applied, the contraction length is 0.05 mm (the above measurement uses a digital caliper 1/100 mm accuracy, The maximum and minimum values obtained by measuring 20 samples). Thus, no matter how the abrasive is pressed against the same surface of the abrasive holder, the surface of the abrasive is a polished surface having a strain of at least 0.05 to 1 mm, and the operator can adjust the pressing force and angle. It is necessary to perform polishing work over time while confirming with the sense of tentacles.

  This is a polishing tool which has a groove in an elastic body and constitutes a plurality of partition portions so that it can be bent. This means that by dividing the polishing holder into several planes, the non-polished surface having a three-dimensional curved surface in the divided plane must be polished with points and lines and polished to the required shape. Don't be. In order to smoothly polish an object to be polished having all three-dimensional non-polished surfaces such as a curved surface and an uneven surface, it is necessary to adjust a pressing force and an inclination angle, which requires skill of an operator.

  Rather than the conventional polishing method that relies on the intuition of the operator or adjusting the tilt angle, the surface of the polishing material is shrunk into the required shape of the object to be polished (ie, shrinking deformation proportional to the hardness). An object of the present invention is to propose a polishing tool capable of polishing a smooth surface easily and easily even by an inexperienced person by polishing smoothly.

  Also, when polishing involving the above factors, the surface of the abrasive material is polished in close contact with the non-polished surface while shrinking and deforming to the required shape, so the elastic surface always has a uniform elastic force. It must be exerted and the operator's pressing force must be evenly transmitted to the entire polishing surface.

  When the other surface fastener to which the abrasive is bonded (in this case, the engaged side) is attached to the abrasive holding body to which the surface fastener is adhered, the surface of the abrasive is distorted. It must be made impossible to do.

  In the present invention, a hole for making the appropriate elastic force and the elastic force of the entire joint surface of the abrasive holding body constant in the mounting plate of the polishing tool used detachably attached to the polishing apparatus is provided. By using an elastic body and a bendable abrasive holding body, the abrasive can be polished while shrinking and deforming in accordance with the required shape of the object to be polished.

When the other surface fastener to which the abrasive is bonded (in this case, the engaged side) is attached to the abrasive holding body to which the surface fastener is adhered by pressure contact, the abrasive holding body is A surface fastener having a thickness of 0.46 to 0.49 mm and a contraction length of 0.01 mm or less when pressure is applied should be used so that the surface of the abrasive cannot be distorted.
(Measurement shall be the maximum value obtained by measuring 20 points of each sample with digital caliper 1/100 accuracy.)

  Further, the polishing method of the polishing tool of the present invention is connected to an intake device using a negative pressure as an intake source from a hole formed in an abrasive, an abrasive holding body, an elastic body, and a polishing plate, and an intake of an arbitrary negative pressure. By using the force and suctioning the surface to be polished, the polishing material performs the polishing operation while elastically deforming to the required shape of the non-polishing surface, and when the polishing device is polished to the shape of the non-polishing surface, the polishing apparatus is turned off. It is assumed that the smoothness of the non-polished surface can be easily confirmed by adhering to the non-polished surface only by the suction force.

  As described above, the present invention makes it possible to polish the surface smoothly while the abrasive is contracted and deformed into the required shape of the object to be polished (that is, contracted and deformed in proportion to the hardness). For non-polished surfaces with a three-dimensional curved surface, polishing with points and lines, which had to be polished to the required shape, shrunk the polished surface into a three-dimensional non-polished surface shape, Since the surface can be polished, the non-polished surface can be polished smoothly and easily without experience.

In addition, the polishing method of the polishing tool of the present invention uses an arbitrary negative pressure suction force to suck the surface to be polished so that the polishing material is elastically deformed into the required shape of the non-polishing surface. Therefore, the operator does not need to adjust the pressing force and angle of the polishing apparatus, and can perform the polishing operation by reciprocating the polishing surface contracted and deformed into the shape of the non-polishing surface in the longitudinal direction.

  At the time when the shape of the non-polished surface can be polished, the polishing apparatus adheres to the non-polished surface only by the suction force, so that the smoothness of the non-polished surface can be easily confirmed.
