JP3222997U - One-touch disk attachment / detachment structure for disk type polishing machine - Google Patents

Abstract

Disclosed is a disc sander that can change the count of sandpaper with one touch. An N (S) pole magnet 2a is embedded in several places of a base disk 2. In each of the exchange disks 3 to 5 for attaching sandpapers 3b to 5b having different counts, S (N) pole magnets 3a to 5a are disposed at the same position as the base disk. One-touch attachment and detachment is possible by attracting the base disk and the replacement disk by magnetic force. [Selection] Figure 1

Description

  The present invention relates to a tool using a disk, and particularly relates to attachment / detachment of a disk attached to a disk sander (disk grinder).

  In the conventional disc sander, sandpaper for polishing is fixed to the disc attached to the disc sander by spray glue or magic tape.

  For this reason, it was not possible to easily replace sandpaper with different counts (coarse, medium, fine ...).

  The sandpaper is not directly attached to the disc attached to the rotating shaft of the disc sander body, but the disc is used as a base disc. Adsorb.

  Work efficiency can be improved by attaching sandpaper with a different count on the replacement disc and attaching / detaching it to the required count disc according to the polishing process.

It is a perspective view which shows the structure of the base disk and exchange disk which made the example of the disk sander in which a disk is attached in a horizontal surface. It is a perspective view which shows the structure of the base disk and exchange disk which made the example of the disk sander in which a disk is attached in a vertical surface.

The magnet N (S) pole is embedded so that the concentric circle cross close to the outer periphery of the base disk is face up. In each replacement disk, an S (N) pole magnet as a counter electrode is embedded at the same position as the base disk as shown in the table. By aligning the magnets, both disks are attracted by magnetic force.
When the disc rotates on a vertical surface, in addition to a structure that is attracted by magnetic force, a structure that processes and fits a pin in the base disc and a hole in the replacement disc is used so that the disc does not slip during polishing work. I can do it.

  The present invention relates to a tool using a disk, and particularly relates to attachment / detachment of a disk attached to a disk type polishing machine.

  In a conventional disk type polishing machine, sandpaper for polishing is fixed to a disk attached to the disk type polishing machine with spray glue or magic tape.

  For this reason, it was not possible to easily replace sandpaper with a different roughness.

  The sandpaper is not directly attached to the disc attached to the rotating shaft of the disc type polishing machine body, the disc is used as a base disc, the sandpaper is pasted on a separately prepared replacement disc, and the base disc and the exchange disc are used with a magnet. Adsorbed by magnetic force.

  Work efficiency can be improved by attaching sandpaper with a different grain size to the replacement disk and attaching / detaching it to the required number of disks according to the polishing process.

It is a perspective view which shows the structure of the base disk and exchange disk which made the example of the disk type grinding machine with which a disk is attached in a horizontal surface.

Claims (2)

  Sandpaper (coarse, medium, fine, etc.) with a different count from the base disk ((2) or (7)) attached to the rotating shaft of the disc sander (disc grinder) body ((1) or (6))・ Establish a counter electrode in several replacement disks ((3) to (5) or (8) to (10)) (add the number if necessary), and attach them both magnetically. In this way, the disc attachment / detachment structure allows the replacement disc to be attached / detached with a single touch.   The structure according to claim 1, wherein pins (7b) are provided at several locations on the base disk, holes ((8b) to (10b)) are provided at positions where the pins are engaged with the replacement disk, and the disk is not displaced by polishing work. Disc attachment / detachment structure as described.
