Such a structure may include various well-known structures including worms and worm gears.

Since the barrel barrel 150 can be rotated from 0 to 90 degrees by rotation of the tilting portion 170, the barrel barrel 150 rotates in a vertical direction and tilts from 0 to 90 degrees. Since it can be rotated in the process and can be rotated in the horizontal direction that is rotated 90 degrees, the abrasive medium and the object to be polished inside the barrel barrel 150 can act effectively centrifugal centripetal force, so the target polishing can be done very effectively and quickly. It is very desirable.

Of course, the rotation time in the vertical direction of the barrel barrel 150, the speed at which the tilting unit 170 is tilted, and the rotation time in the vertical direction of the barrel barrel 150 can be controlled by the controller 190. In addition, of course, the control unit 190 may control the tilting unit 170 through a switch including a proximity switch and an optical switch that do not detect whether the tilting unit 170 is positioned in a vertical direction or a 90 degree direction.

When the user presses the'automatic' switch provided in the control unit 190 by this structure, the barrel barrel 150 rotates in the vertical direction for a set time, then tilts and rotates in the 90 degree direction, and the barrel barrel 150 is set in the horizontal direction. After rotating in time, the tilting unit 170 may be returned to its original position.

3A and 3B, the center of gravity of the upper portion of the X-axis direction (refer to the'A' mark in FIG. 3A), which is the horizontal axis direction of the tilting axis 175, is referred to as'Ma', and the tilting axis ( When the center of gravity of the lower portion of the X-axis direction (refer to the'B' mark in FIG. 3A) in the horizontal axis direction of 175) is referred to as'Mb', the balance unit 180 rotates when the tilting unit 170 tilts Since the center of gravity Ma and Mb are changed according to the tilting angle of the tilting unit 170, it is a function to keep the change of the balance as constant as possible.

That is, when the revolution part 140 and the rotating part 160 rotate at a very high speed to polish the object to be polished of the barrel barrel 150, and the balance of the center of gravity collapses as a result of this high-speed rotation, the barrel polisher 100 It is not desirable because the vibration of itself shortens the life of the bearing and the like, and noise can be generated a lot. In addition, since the barrel barrel 150 can accommodate various types of abrasive media or objects to be polished, this phenomenon may be more severe.

The balance unit 180 having such a function, the center of gravity of the tilting unit 170 in the first angle range (see'θ1' in FIG. 3A) in which the tilting unit 170 is tilted and rotated to a set 35 degree, for example. The first weight 184 to add weight to maintain the balance, and, for example, having a weight that is further added to the first weight 184 in a second angle range in which the tilting unit 170 is rotated by 60 degrees. It includes a second weight (185), such as the first weight 184 and the second weight 185 is coupled to the tilting unit 170 to transmit the combined weight to the tilting unit 170 in the form of wire A weight wire 189, a guide roller 186 coupled to the housing 110 to guide and support the weight wire 189, and a first weight passing through the first weight 184 and the second weight 185 It is preferable to have a cradle 181 and a second weight cradle 182. In addition, the balance unit 180 is a guide wire that is coupled to the first weight 184 and the second weight 185 to guide the first and second weights 184 and 185 to stably move in a vertical direction without shaking. It is preferable to further include (187).

In addition, the width of the first weight 184 so that the first weight 184 can move upward by adding the second weight 185 in the process of moving along the weight wire 189 and the guide wire 187 3B'see'W1') is less than the passage width of the second weight cradle 182 (see'W2' of FIG. 3B), the second weight 185 can be seated on the second weight cradle 182 So, the width of the second weight 185 (refer to'W3' in FIG. 3B) is formed to be larger than the passage width W2 of the second weight holder 182.

By this configuration, the tilting unit 170 is first, for example, in the process of tilting and rotating from 0 degrees (for example, the state shown in FIG. 2) to 90 degrees (for example, the state shown in FIG. 3B). The weight added to the tilting unit 170 by the first weight 184 is added to the tilting unit 170, and the weight of the first weight 184 plus the second weight 185 is added from the set second angle range. In addition to 170), the tilting unit 170 can effectively maintain the balance of the tilting unit 170 according to the tilting angle.

The operation process of the barrel polishing machine 100 having such a configuration will be described in detail with reference to FIGS. 1 to 3B.

First, when the user presses the'automatic' switch on the control unit 190, the revolution unit 140 and the turntable 130 are rotated by the revolution driving unit 120. The barrel barrel 150 is rotated by the rotation of the barrel rotating pulley 149 interlocked with the barrel rotating pulley 149 by the rotation of the revolving portion 140 while the barrel barrel 150 is also rotated by the rotation of the rotating plate 130. Is rotated with respect to the turntable 130.

The surface of the object to be polished is polished by the friction and contact between the object to be polished and the polishing medium inside the barrel barrel 150 by centrifugal force and centripetal force.

When the rotation and rotation of the barrel barrel 150 is performed for a set time in the horizontal direction of the barrel barrel 150, the tilting driving unit 177 operates to gradually rotate the tilting unit 170 as shown in FIG. 3A. The barrel barrel 150 is also rotated while being inclined at a set angle, and the centrifugal force and centripetal force acting on the contents of the barrel barrel 150 may be different from the center of gravity in the vertical direction. As described above, the centrifugal force and centripetal force acting on the object to be polished and the abrasive medium allow mixing, friction, and contact of the object to be polished in various directions for more effective polishing.

In this process, the balance unit 180 adds the weight of the first weight 184 to the tilting unit 170 as shown in FIG. 3A (the first weight 184 is'L1 as shown in FIG. 3A). 'Move by a distance) to maintain the balance of the tilting unit 170.

Next, by gradually tilting and rotating the tilting unit 170, the barrel barrel 150 is rotated and rotated for a set time in a state rotated 90 degrees as shown in FIG. 3B. In this process, the weight in which the second weight 185 is added to the first weight 184 acts on the tilting unit 170 to more effectively maintain the balance of the tilting unit 170. In addition, the barrel barrel 150 rotates at a high speed because the tilting driving unit 177 itself can maintain the balance more stably than maintaining the balance at a 90 degree position by maintaining the balance. Even if it can effectively reduce the noise or vibration of the barrel grinding machine 100, polishing can be made efficiently.

Of course, the first weight 184 and the second weight 185 may be changed to various weights, and the combined positions may be variously changed.

Of course, in the process of reversing and returning to the original position, first the second weight 185 is seated on the second weight cradle 182 and finally the first weight 184 can be mounted on the first weight cradle 181. It has a feature that can be added to the tilting portion 170 variably according to the angle to be added to maintain the balance weight.

In addition, a plurality of weights may be sequentially added in various ways according to the tilting angle of the tilting unit 170 as well as the first weight 184 and the second weight 185.

Thus, according to the present invention, it is possible to provide a tiltable barrel polishing machine capable of tilting the rotating body equipped with the barrel and the vertical axis around the horizontal axis while rotating the rotating plate equipped with the barrel and rotating around the vertical axis. .

In addition, since the barrel barrel pivoting on the turntable tilts around the horizontal axis, a horizontal and vertical fluidized bed is generated in the charge in the barrel barrel, and the abrasive medium flows from the top, bottom, left and right to the object to be polished by the flow of the charge. It is possible to provide a tiltable barrel polishing machine in contact with which the entire object to be polished can be efficiently frictionally polished by a polishing medium.

In addition, even a compact and complex-shaped product such as, for example, a dental prosthesis, and even if there is a specific gravity difference between the abrasive medium and the object to be polished, the tiltable barrel polishing machine can be uniformly and reliably polished throughout the object to be polished. Can provide.

In addition, it is possible to provide a tiltable barrel polishing machine that is simple and convenient in structure and can effectively maintain a balance even in a tilting process.
