BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grindstone unit installed in a grinder, and more particularly, to a grindstone unit disassembly apparatus for a grinder, which is capable of automating the disassembly assembly process of a grindstone unit.

In general, the grindstone unit is a fine and precise part that is assembled and used in a polishing machine that performs a polishing operation such as a roll, and in the case of a new product, the total weight of the grindstone unit is about 75Kg.

Here, the grindstone unit is provided with a grindstone which is in direct contact with the abrasive products such as rolls along the outer circumferential surface of the grindstone metal and the flange is mutually bowled, when the grindstone unit is used for a certain period of time, It is reduced, so it is replaced and reused.

In addition, in the case of replacing the grindstone metal and the flange and the grindstone of the grindstone unit, it is to be reused after disassembly and assembly through manual work after transferring to the workshop using a transfer device such as a crane.

In other words, in order to disassemble and assemble the grindstone unit, the grindstone unit assembled in one set is usually laid down and disassembled by a plurality (about 10) tightening bolts, and then disassembled while hitting the flange and the grindstone. With the grindstone metal lying on the floor of the workshop, two workers on it hold the grindstone and the flange and perform the assembly work in turn.

However, in order to disassemble and assemble the grindstone unit, the grindstone unit is laid in the direction of applying force during the loosening or tightening of the tightening bolt, so that the disassembly and assembly work is not easy.

In addition, in the process of disassembling the grindstone unit, the worker handles a heavy object in an unstable posture bent at the waist, so that a back injury may occur frequently, and it may be lifted directly without a separate mechanism in the process of disassembling the flange and knowledge. Therefore, the work time is consumed a lot, especially when the flange or the grindstone metal does not fall well, there was a problem that can be damaged because it is separated by a separate blow tool.

In addition, since the grindstone unit is a heavy material, the worker falls down on the floor in order to avoid injury. In this case, when a fine deformation occurs in the grindstone metal, which is a precision part, or is crushed due to impact, the grindstone is shaken during operation. There is a problem that is poor to adversely affect the quality of the product produced.

Accordingly, the present invention has been made in order to solve the above problems, assembling the grindstone unit using a surface plate for sliding along the vertical direction and a moving platform for sliding along the left and right directions. It is an object of the present invention to provide a grindstone unit for assembling and grinding, which can be disassembled using an extractor and a separator.

The present invention for achieving the above object, it is possible to separate the movable table and the flange which can be moved by mounting the disassembly assembly and the grindstone that can be disassembled and assembled the grindstone metal and the grindstone and the flange in the original standing state And a grindstone unit disassembly and assembly device including a flange extractor adapted to move the flange and the flange.
