Description

[0001] The present invention relates to a wheel structure for a grinding apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wheel structure used in a polishing apparatus and relates to a wheel structure rotated by a motor.

Generally, the polishing apparatus is detachably fixed to an abrasive member coated with diamond powder or an abrasive member made of resin mixed with diamond powder on an abrasive wheel rotated by a motor. As the grinding wheel rotates, the grinding member rotates to smoothly polish the surface of the floor or the wall or to remove impurities.

Such a polishing apparatus is widely used in industrial fields such as construction and interior construction. The grinding wheel is rotated at a high speed by a motor to polish the surface of the object to be polished. One example of such a wheel structure for a polishing apparatus is disclosed in Published Utility Model No. 2010-0009796.

A conventional wheel structure for a polishing apparatus includes a wheel body rotated by a motor and an abrasive member detachably fixed to the wheel body. Generally, the abrasive member is coated or mixed with poly-crystalline diamond powder (PCD) on a metal or a synthetic resin. The polishing member is detachably fixed to the wheel body. This is because the abrasive members are worn out depending on use and therefore exchange is indispensable. The abrasive member is detachably fixed to the wheel body by means such as a magnet, a valcro, a bolting, a press-fit, or the like. In recent years, the use of a magnet or a balck-type fixing means has been increasing to facilitate the exchange of the abrasive member.

However, when the abrasive member is fixed to the wheel body and friction occurs on a floor or a wall of a building to be polished while rotating at a high speed, the abrasive member frequently unexpectedly deviates from the wheel body. When the polishing member is detached from the wheel body while the polishing member is rotating, there is a problem in that it can damage the body of a person who is around the worker as well as the worker, and the life of the polishing member is shortened.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wheel structure for a polishing apparatus, which is improved in structure of a wheel for a polishing apparatus and is prevented from being detached from a wheel body.

According to an aspect of the present invention, there is provided a wheel structure for a polishing apparatus, comprising: a wheel body rotated by a motor; And

And an abrasive member detachably fixed to the wheel body, the wheel structure comprising:

And a release preventing member disposed to surround the outer circumference of the abrasive member and fixed to the wheel body to prevent the abrasive member from being detached from the wheel body.

Preferably, the release preventing member is fixed to the body by any one of a bolt, a ball, a magnet, and an adhesive method.

It is preferable that the abrasive member is fixed to the wheel body by any one of bolt, ball, magnet, adhesive, and interference fit.

A plurality of the abrasive members may be provided.

The wheel structure for a polishing apparatus according to the present invention is characterized in that the abrasion member is arranged to surround the outer periphery of an abrasive member detachably fixed to the wheel body and is fixed to the wheel body, So that it is possible to secure the stability of the working environment and to prolong the life of the polishing member.

FIG. 2 is a view showing a state in which the wheel structure for the polishing apparatus shown in FIG. 1 is assembled. 3 is a sectional view taken along the line III-III shown in Fig. FIG. 4 is a view corresponding to FIG. 3, illustrating another embodiment. FIG. 5 is a view corresponding to FIG. 3, illustrating another embodiment. FIG. 6 is a view corresponding to FIG. 3, illustrating another embodiment. 7 is a view for explaining a structure of a release preventing member according to another embodiment.

Referring to FIGS. 1 to 7, a wheel structure 10 for a polishing apparatus according to a preferred embodiment of the present invention includes a wheel body 20, a polishing member 30, and a separation preventing member 40.

The wheel body 20 is rotated by a motor (not shown). The wheel body 20 is, for example, a disc-shaped structure as shown in FIG. In the center of the wheel body 20, a coupling hole 22 for coupling with a rotation axis (not shown) of the motor is provided. The wheel body 20 may be made of a metal such as carbon steel. On one side of the wheel body 20, there is provided a structure for detachably fixing a polishing member 30 to be described later. 1 and 3, a valcro member is provided on one surface of the wheel body 20. The wheel body 20 may have a structure in which the abrasive member 30 is fixed to the wheel body 20 in a bolt, magnet, adhesive, or interference fit manner in addition to the valve member. That is, the wheel body 20 and the polishing member 30 can be fixed by the magnet 55 as shown in FIG. 5, the wheel body 20 and the abrasive member 30 may be fixed by an adhesive 65. Meanwhile, as shown in FIG. 6, the abrasive member 30 may be fixed to the wheel body 20 in an interference fit manner.

The abrasive member 30 is detachably fixed to the wheel body 20. The abrasive member 30 may be fixed to the body by, for example, a bolt, a ball, a magnet, or a bonding method. The abrasive member 30 may be manufactured by bonding a grinding tip made of a polycrystalline diamond material to a frame made of a metal such as carbon steel by welding or bonding. Meanwhile, the abrasive member 30 may be manufactured by processing a mixture of a resin and a polycrystalline diamond powder by an injection molding method. The abrasive members 30 may be provided on the wheel body 20, respectively. 1 and 2 show that a plurality of polishing members 30 are provided.

The release preventing member 40 is a member that plays a key role in the present invention. The release preventing member 40 may be made of the same material as the wheel body 20 or a material different from the wheel body 20. The release preventing member 40 may be fixed to the wheel body 20 by a bolt, a ball, a magnet, an adhesive method, or the like. The release preventing member 40 is provided to prevent the abrasive member 30 from being detached from the wheel body 20. Since the polishing member 30 rotates integrally with the wheel body 20 during operation, the wheel body 20 receives a centrifugal force in a tangential direction with respect to the rotation direction of the wheel body 20. Therefore, the release preventing member 40 is disposed so as to surround the outer circumference of the abrasive member 30. [ The release preventing member 40 may be detachably fixed to the wheel body. The coupling structure of the separation preventing member 40 and the wheel body 20 may be implemented in various ways as shown in FIGS.

Hereinafter, the operation and effect of the wheel structure 10 for a polishing apparatus according to the present embodiment constructed as described above will be described in detail, for example, when the wheel structure 10 for a polishing apparatus rotates the surface of a floor or a wall while rotating by a motor. .

The wheel structure 10 for a polishing apparatus is mounted on a polishing apparatus and polished on the floor while being rotated by a motor. In this case, the operator grasps the handle of the polishing apparatus and performs work. However, when the wheel structure 10 for a grinding apparatus rotates at a high speed, the grinding member 30 receives a centrifugal force in a tangential direction with respect to the rotating direction of the wheel body 20. The centrifugal force exerts a force to move the polishing member 30 to the outside of the wheel body 20. The force acting as a centripetal force against the centrifugal force is a force applied by the fixing means of the abrasive member 30 and the wheel body 20. In other words, the abrasive member 30 can be fixed in a ball joint manner as shown in FIGS. 1 and 2, and the balancing force acts as a centripetal force. However, since the method of fixing the abrasive member 30 and the wheel body 20 is not permanent, when the frictional force with the floor instantaneously increases, that is, when the rotation of the wheel structure 10 The abrasive member 30 may be unexpectedly detached from the wheel body 20 when an obstacle obstructing the wheel body 20 is attached. Since the release preventing member 40 is disposed to surround the outer circumference of the abrasive member 30 and is fixed to the wheel body 20 to prevent the abrasive member 30 from being detached from the wheel body 20 .

In this way, the separation preventing member prevents the abrasive member from being detached from the wheel body unexpectedly according to the floor state while the polishing member is rotating integrally with the wheel body. Therefore, the risk of being applied to the body of the worker can be remarkably reduced by providing the release preventing member, thereby securing the safety of the worker and prolonging the life of the polishing member remarkably.

 While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications can be made by those skilled in the art within the technical scope of the present invention. Is obvious.
