The present invention relates to a surface polishing machine using a single motor, and more particularly, a surface polishing machine having a simple structure, easy manufacturing, and excellent polishing effect by rotating each polishing unit installed in the body together with the body using a single motor. It is about.

Surface grinders are used to grind structures, such as concrete, stone, wood, etc., to remove oxides from the surface or to make the surface new and smooth.

The surface polisher generally includes a body and a polishing unit installed on the body, and the polishing unit is also rotated and polished while the body rotates. In this case, when the body and the grinding unit are driven by the respective motor, there is an advantage that the rotation of the body and the grinding unit can be controlled independently, but the configuration of the device is complicated, the failure can be frequent and the manufacturing cost increases.

However, when rotating both the body and the polishing by a single motor, there is a simple configuration and advantageous maintenance. US Pat. No. 7,140,957, US Pat. No. 5,637,032 and the like disclose examples using a single motor. At this time, a plurality of polishing units are installed at the bottom of the polishing machine, and each polishing unit is connected to the pulley and the belt by a single motor to rotate at the same rotational speed. Some of the rotating shafts of the plurality of polishing units extend through the upper plate of the body and are connected by a belt, so that when the polishing unit rotates, the entire body rotates. In other words, each grinding unit receives the driving force from a single motor is rotated, and this is a two-stage power transmission method in which the body connected to the polishing unit rotates again.

However, when driving in this manner, since the driving force of the motor is transmitted to the body only through the polishing portion, there is a problem in that the driving force transmission to the body is weakened when an impact or vibration occurs in the polishing portion during operation. In addition, since the driving method using only the pulley and the belt has a problem that the slip of the belt occurs when used for a long time.

The present invention for solving the above-described problems, by using a single motor to transfer the driving force to the body and the polishing unit each independently provides a surface polishing machine using a single motor with a simple structure, easy manufacturing and excellent polishing effect I would like to.

According to the present invention for achieving the above object, a surface polishing machine for use in polishing the surface of the workpiece, the body drive unit for driving the body; A polishing unit driving unit for driving a polishing unit installed in the body; And a motor providing a driving force to the body and the polishing unit. It includes, The body drive unit and the polishing unit driving unit, the surface polishing machine using a single motor, characterized in that the driving force is independently transmitted simultaneously from the motor through the same rotation axis.

The body drive unit preferably includes a plurality of sprockets and a plurality of drive chains rotatably connected to the plurality of sprockets.

Here, one of the plurality of sprockets, it is preferable to mesh with the internal chain is installed in a circle around the outer periphery in the upper upper plate of the body.

Preferably, the polishing unit driving unit includes a plurality of pulleys and a driving belt connecting the plurality of pulleys.

In this case, it is preferable that one of the plurality of pulleys is a tension pulley so that the driving belt can maintain a proper tensile force.

The lower end of the polishing portion is provided with a polishing plate for directly contacting the surface of the workpiece and polishing the workpiece, the polishing plate is preferably a metal or resin.

The direction of rotation of the body can be adjusted in a clockwise or counterclockwise direction, and the rotational direction of the body and the polishing unit is opposite, the surface polishing machine using a single motor.

According to the present invention as described above, even if a single motor is used, the surface polishing machine using a single motor having a simple structure and easy polishing but excellent polishing effect can be provided by transmitting driving force to the body and the polishing unit independently. .

Accordingly, according to the present invention, since the body is rotated by using a chain and a sprocket, there is no risk of slip phenomenon compared to the method of rotating by using only a conventional pulley and a belt, and the driving force can be transmitted more reliably and excellent in durability. .

In addition, according to the present invention, since there is no need for a separate reducer because of the chain deceleration method, there are fewer application parts, so it is excellent in price competitiveness and easy maintenance of the surface polishing machine.

Figure 2 is a plan view of the body drive unit of the surface polishing machine using a single motor according to the present invention.
3 is a perspective view of a polishing unit driving unit of a surface polishing machine using a single motor according to the present invention.
Figure 4 is a perspective view of one embodiment of a polishing plate attached to the bottom plate of the body.

Hereinafter, a surface polishing machine using a single motor according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the surface polishing machine using a single motor according to a preferred embodiment of the present invention includes a body driving unit 21 for driving the body 22 and a polishing unit 32 installed in the body 22. It includes a polishing unit driving unit 31 for driving. The body 22 and the polishing unit 32 may receive a driving force from the motor 11 installed on the motor mounting plate 12, and the body driving unit 21 and the polishing unit driving unit 31 may be one motor. It can be driven through the rotary shaft (13). Therefore, the driving force from the motor 11 can be independently transmitted to the body driving unit 21 and the polishing unit driving unit 31 simultaneously from the motor 11.

In the present specification, the driving force is independently transmitted, but the driving force is transmitted from the single motor 11, but the body 22 and the polishing part 32 rotate without being influenced by each other. That is, the driving force is not transmitted from the motor 11 to the polishing unit 32 via the body 22 or vice versa, but directly from the motor 11 to the body 22. Driving force can be transmitted to the and the polishing unit 32, respectively.

The body 22 includes an upper plate 22a and a lower plate 22b, the upper part of the upper plate 22a has a body driving unit 21 and the lower part of the upper plate 22a is a polishing unit driving unit 31. There is).

The polishing unit 32 may include a polishing plate 34 and a plate cover 36. In addition, although not shown in the drawing, a tool plate made of a material such as metal or resin may be attached to the lower surface of the polishing plate 34 in contact with the workpiece. However, in the present specification, unless there is a special mention of the tool plate, the polishing plate 34 will be described as a concept indicating a state in which the tool plate is attached.

The plate cover 36 couples the polishing plate 34 to the body 22 and prevents dust from entering during operation into the polishing plate 34. In addition, even if the tool plate attached to the polishing plate 34 is weakened during the operation, and thus detached from the polishing plate 34, the plate cover 36 can prevent the tool plate from being separated from the polishing unit 32. .

The body 22 may rotate on the motor rotation shaft 13 through the body bearing 15, and the polishing part 32 may also rotate on the polishing part rotation shaft 35 through the polishing part bearing 37.

As shown in Figures 1 and 2, the body drive unit 21 according to the present invention may include a plurality of sprockets, and a plurality of drive chains 28 that can be connected to the plurality of sprockets to rotate. .

As the motor shaft 13 rotates, the driving sprocket 29 rotates, and accordingly, the first sprocket 23 connected to the driving sprocket 29 and the driving chain 28 may rotate. Since the second sprocket 24 has the same axis of rotation as the first sprocket 23, when the first sprocket 23 rotates, the second sprocket 24 installed on the upper end of the first sprocket 23 also rotates together. .

Since the second sprocket 24 is connected to the third sprocket 25 through the driving chain 28 again, the third sprocket 25 may rotate as the second sprocket 24 rotates. Since the fourth sprocket 26 having the same rotation axis is provided at the lower end of the third sprocket 25, the fourth sprocket 26 can rotate up to the fourth sprocket 26.

1 and 2, the internal chain 27 may be circularly installed near the outer circumference of the upper plate 22a of the body 22. The fourth sprocket 26 is engaged with the internal chain 27 to operate. The fourth sprocket 26 serves as an internal gear and the internal chain 27 serves as an external gear, so the fourth sprocket 26 and the internal sprocket 26 are internally engaged. The chain 27 may serve as an internal gear.

Since the internal chain 27 is fixed to the upper plate 22a by welding or the like, when the internal chain 27 engaged with the fourth sprocket 26 rotates, the body 22 may rotate.

However, the drawing shows an example in which the body 22 rotates clockwise when the motor rotation shaft 13 rotates clockwise as in the arrow direction, for example, but the rotation direction of the motor rotation shaft 13 is counterclockwise. It can also be adjusted as in this case the body 22 can also be rotated counterclockwise.

At this time, as shown in Figure 2, the sprockets of different sizes are respectively connected to rotate the body 22, so that the body 22 compared to the motor rotation shaft 13 may have an appropriate reduction ratio. As a result of the chain deceleration method, the power is securely transmitted to the body 22 which requires a certain rotation in the polishing machine, thereby enabling stable polishing.

As shown in FIG. 3, the polishing unit driving unit 31 according to the present invention may include a plurality of pulleys and a driving belt 45 connecting the plurality of pulleys.

As the motor shaft 13 rotates, the driving pulley 14 rotates, and the driving pulley 14 is connected to each of the polishing part pulley 33 and the driving belt 45, so that the driving pulley 14 rotates. As a result, the abrasive pulley 33 may also rotate. Due to the difference in diameter between the driving pulley 14 and the polishing part pulley 33, the polishing part 32 (see FIG. 1) with respect to the motor rotation shaft 13 can be decelerated at an appropriate reduction ratio.

When driving using a belt, it is necessary to prevent slippage. Therefore, the idle pulley 41 provided on the pulley rotation shaft 43 can be appropriately disposed so as to increase the contact area between the drive pulley 14 and the polishing part pulley 33 and the drive belt 45. As a result, the driving belt 45 is reliably wound on the polishing part pulley 33, so that the driving force transmission from the motor 11 can be surely performed. In addition, the tension pulley 46 may be installed at one side of the lower plate 22b because it is necessary to give an appropriate tensile force to the driving belt 45 when the driving belt 45 rotates.

As shown in FIG. 3 and FIG. 4, the polishing part rotation shaft 35 may be connected to the polishing plate 34 through the lower plate 22b. Therefore, as the polishing part pulley 33 rotates, the polishing plate 34 rotates, and the polishing operation can be performed while the polishing plate 34 is in direct contact with the surface of the workpiece.

As shown in the arrow direction of FIG. 3, when the motor rotation shaft 13 rotates clockwise, the polishing part pulley 33 rotates counterclockwise, and thus the polishing plate 34 may also rotate counterclockwise. As a result, the rotational direction of the body 22 and the polishing plate 34 is reversed, but the rotational direction of the motor 11 may be appropriately adjusted in a clockwise or counterclockwise direction depending on the polishing operation.

As such, according to the surface polishing machine using the single motor of the present invention, the body 22 is driven according to the chain deceleration method, and the driving force is transmitted to the polishing part 32 by the driving belt 45 so that the body 22 and the polishing are polished. All of the parts 32 are more durable than the belt method alone, and the driving force can be more reliably transmitted. In addition, since there is no need to use a separate reducer, the number of parts is reduced and maintenance is easy.

In addition, according to the surface polishing machine using a single motor of the present invention, even when a single motor 11 is used, the driving force is independently transmitted to the body 22 and the polishing portion 32, so that the polishing portion 32 is impacted during the polishing operation. Even if vibration or vibration is applied, the body 22 may be smoothly rotated.

As described above, the surface polishing machine using the single motor according to the present invention has been described with reference to the preferred embodiment of the present invention. However, it should be understood that the present invention is not limited to the above-described embodiments and drawings, and various modifications and changes may be made by those skilled in the art without departing from the scope of the present invention.
