Tool box structure of polisher {Tool box of calender}

The present invention relates to a tool box structure of a polisher, and more particularly, to a tool box structure of a polisher for improving the gloss of the inner and outer floors of a building formed of marble or the like.

In general, a calender is a machine that polishes by friction, and removes the time when rubbed the floor of a building formed of marble by a rotating pad or brush to remove the gloss of the building floor. It is a device to improve.

Figure 1a is a perspective view of a conventional polisher commonly used, Figure 1b is an exploded perspective view of the polishing portion of the conventional polisher.

As shown in FIGS. 1A and 1B, a conventional polisher includes a motor cover 120, a motor cap 130, a workbench 140, a handle 160, and a motor (not shown) surrounding a motor (not shown) that provides rotational force. An operation lever 150 for controlling the operation of the < RTI ID = 0.0 >) < / RTI > and a polishing unit 195 for performing a polishing operation in direct contact with the building floor, wherein the motor is generally used with a single phase motor, and the polishing Part 195 includes a polishing pad 193 that rubs the floor of the building to improve the glossiness of the floor; A rotating plate 192 having the polishing pad 193 attached to a lower surface thereof; It includes a unidirectional rotary plate holder 190 is coupled to the center of the rotating plate 192, the casting holder 170 is connected to the shaft of the motor and configured to attach and detach the unidirectional rotary plate holder 190. .

When using a conventional polisher having such a configuration, first, the protrusion 180 protruding from the casting holder 170 is inserted into the slot 191 of the unidirectional rotating plate holder 190 fixed to the center of the rotating plate 192 and the rotating plate 192. ) By rotating the casting holder 170 and the rotating plate 192 by rotating in one direction, and then operating the motor by operating the operation lever 150 so that the polishing pad 193 rotates to perform polishing work on the building floor. .

Thereafter, when the work is completed, the rotary plate 192 is rotated in the other direction to release the coupling of the casting holder 170 and the rotary plate 192, and then separate and store the rotary plate 192.

However, the conventional polisher of such a configuration is a single-phase motor is generally used as mentioned above, the single-phase motor is a motor that operates with single-phase electricity (electricity made of one power coil), expensive and bulky, especially the motor Difficult to adjust the rotational speed of the beginner had difficulty using the polisher.

That is, when the polisher is operated due to the characteristics of the single phase motor, the rotation speed of the single phase motor is rapidly accelerated to about 1,600 rpm to about 1,800 rpm. Accordingly, the polishing unit 195 connected to the rotating shaft of the single phase motor is also inevitably accelerated and rotated, thereby inevitably. The initial vibration of the polisher was so large that there was a risk that a beginner could hurt his back.

In addition, such a rapid acceleration rotating polisher has a lot of difficulty to perform the polishing operation by the beginner.

On the other hand, as the motor shaft rotates in only one direction due to the characteristics of a general single phase motor, the polishing pad 193 connected to the motor shaft also rotates in only one direction, so that the wear of the polishing pad 193 is biased only in one direction, There was a problem that the replacement time of 193 is shortened, and as a result, the maintenance / maintenance cost of the polisher was increased.

In addition, the conventional polishing pad 193 is attached to the rotating plate 192 in one plate shape, so if there are grooves such as irregularities on the floor to be worked, there is a problem in that the polishing operation is not properly performed on the grooves. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and provides a tool box structure of a polisher configured to prevent a rapid initial rotation of the polisher from rotating by mounting a three-phase motor capable of controlling the rotational speed of the polisher.
