Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

1 is a perspective view showing a deburring wheel 10 according to an embodiment of the present invention, Figure 2 is a front view showing a deburring wheel 10 according to an embodiment of the present invention.

As shown in FIG. 1 and FIG. 2, the deburring wheel 10 according to the present invention has a deburring coupled to the outer peripheral surface of the core portion 11 and the core portion 11 coupled to the rotating shaft 20 of the deburring apparatus 100. And a portion 12.

The core part 11 is coupled to the rotating shaft 20 of the deburring device 100 and serves to transmit the rotating force of the rotating shaft 20. That is, when the rotating shaft 20 of the deburring apparatus 100 is rotated by a motor or the like, the force is transmitted to the deburring portion 12 made of a parent material, which will be described below, to rotate the deburring portion 12.

The core portion 11 is preferably manufactured to be detachable from the rotation shaft 20 of the deburring device 100. When the deburring portion 12 deburrs the metal product by rotation, the deburring part 12 is worn out by friction, and thus, frequent replacement is necessary. Therefore, by making the core portion 11 detachable from the rotating shaft 20, it is possible to save time and cost required for replacement work.

In addition, the core part 11 may be fixed to the rotation shaft 20 through the fastening means 11a.

3 is an exploded perspective view showing that the rotating shaft 20 and the core portion 11 of the deburring wheel are coupled by the fastening means 11a.

Representative fastening means (11a) include those by bolt fastening. As shown in FIG. 3, the core part 11 is fixed to the rotation shaft 20 by a plurality of bolts, so that the rotational force of the rotation shaft 20 is transmitted to the core portion 11.

In addition, as shown in FIG. 4, one or more ribs 21 protrude from the outer circumferential surface of the rotary shaft 20, and the inner circumferential surface of the core part 11 has the rotary shaft 20 from which the ribs 21 protrude. It may be formed to engage with. Preferably, the ribs 21 are formed on the outer circumferential surface of the rotation shaft 20 at three angles of 120 °. It is difficult to sufficiently transmit the rotational force of the rotating shaft 20 to the core portion 11 only by fixing the core portion 11 to the rotating shaft 20 with the fastening means 11a, and the fastening means 11a is rotated at high speed. Because of the possibility of damage by a separate rib 21 on the rotating shaft 20 is to transmit the rotational force to the core portion (11). This configuration is necessary for smooth rotational force transmission, especially when the cross-sectional shape of the rotating shaft 20 is circular.

In addition, the rotating shaft 20 has a polygonal cross section, and the inner circumferential surface of the core part 11 may be formed to be engaged with the rotating shaft 20. For example, as shown in FIG. 5, a cross section of the rotation shaft 20 may be a hexagon, and an inner circumferential surface of the core part 11 may also be formed in a hexagon so as to be engaged with the cross section, without a separate rib 21. The rotational force of 20 can be sufficiently transmitted to the core portion 11. The shape of the cross section of the rotating shaft 20 may be manufactured in various shapes such as triangle, square, pentagon, as well as the hexagon.

The core combined with the rotating shaft 20 may rotate clockwise or counterclockwise according to the rotating direction of the rotating shaft 20. Therefore, in consideration of this, even if the rotation shaft 20 rotates in any direction, it is necessary to form the rib 21 as described above, or to form a cross section of the rotation shaft 20.

As shown in FIG. 1, a deburring portion 12 formed of a parent material is coupled to an outer circumferential surface of the core portion 11.

The deburring portion 12 rotates in accordance with the rotation of the core portion 11 to remove burrs protruding from the object 30 by rubbing against the target product made of metal or the like.

In the related art, the deburring portion 12 is formed of sandpaper or made of a metal material such as wire, and thus is not suitable for deburring products having various three-dimensional shapes.

However, according to the present invention, as shown in FIG. 1, the deburring portion 12 is formed of unknown material, thereby enabling uniform deburring not only for 2D but also for 3D three-dimensional shapes formed to a considerable depth. In the case of the parent material, it is very flexible and can penetrate freely to the deep position of the product, and there is an advantage that it can cope with various types of products by adjusting the density, length, thickness, etc. of the mother.

In particular, the simulated material of the deburring portion 12 according to the present invention is preferable to remove the burr by increasing the friction force by including the abrasive.

In addition, the thickness and density of a simulation can be changed and used according to the target object 30. FIG. If the simulation density is high, the deburring may be good, but since the simulation may be difficult to insert into the interior of the object 30, it is preferable to select the thickness or density of the simulation in consideration of the shape or material of the object 30.

FIG. 6 is a perspective view illustrating a deburring apparatus 100 according to an embodiment of the present invention, and FIG. 7A is an enlarged perspective view of a main part of the deburring apparatus 100 of FIG. 6.

As shown in FIGS. 6 and 7A, the deburring apparatus 100 according to the present invention has a deburring wheel 10 coupled to the conveying unit 110 and the rotating shaft 20 for carrying the object 30 to be deburred back and forth or from side to side. It may be configured to include a control unit 130 for controlling the driving of the head portion 120 and the transfer unit 110 and the head portion 120 to remove the burr of the object 30 by rotating the (Burr). .

The transfer unit 110 is a portion that is responsible for transporting the object 30 to be deburred, and transfers the object 30 to a conveyor belt or the like along the x-axis direction (front and rear direction) as shown in FIG. 7. In addition, the transfer unit 110 may transfer the object 30 to the left and right. When the object 30 can be transferred from side to side as well as from side to side through the transfer unit 110, there is an advantage in that the side portion of the object 30 is easily deburred. This will be described in detail below.

The head part 120 is a part which removes burr by rotating the deburring wheel 10 and rubbing the object 30.

The head part 120 may include a main head part 121 which completely removes a burr of the upper surface part of the object 30 and a burr that is not deburred by the main head part 121 and a burr part which is not deburred by the main head part 121. It may be composed of an additional shaft 122 for removal.

Therefore, the main head portion 121 or the additional shaft 122 is basically provided with a deburring wheel 10 and a motor or the like for rotating the deburring wheel 10 is provided.

8 is a plan view of the deburring apparatus 100 including the main head portion 121 viewed from above.

As shown in FIG. 8, the main head portion 121 includes one revolving shaft 121a and a plurality of revolving shafts 121b on which the deburring wheel 10 is mounted. , To drive back and forth or left and right to remove the burr. Up, down, front, or left and right driving of the main head unit 121 is controlled by the controller 130 to be described later.

The revolving shaft 121a is a portion that is the center of the coupling of the plurality of revolving shafts 121b, and the revolving shaft 121a is controlled up, down, front or rear, and the main head portion 121 including the rotating shaft 121b is the object ( The burr is removed by contacting the upper portion of the substrate 30.

The revolution shaft 121a rotates the rotation shaft 121b to remove burrs of portions that are not deburred between the rotation shaft 121b and the rotation shaft 121b.

As the idle shaft 121a is controlled up and down, front and rear or left and right, the entire main head portion 121 is deburred at the upper portion of the object 30, and the rotation direction of the idle shaft 121a compensates for the deburring of the rotating shaft 121b. It is intended to be rotated clockwise or counterclockwise.

The plurality of rotating shafts 121b may be formed such that the six rotating shafts 121b are circularly disposed about the rotating shaft 121a, and the deburring wheel 10 is coupled to each rotating shaft 121b to rotate. As a result, the burr on the upper surface of the object 30 is removed.

In particular, in the present invention, since the burr is removed by attaching the deburring wheel 10 formed of the above-mentioned parent material to the rotating shaft 121b, it is possible to uniformly deburr even various products.

At this time, the rotation direction of each rotation shaft 121b can be set differently, and it is preferable to set the rotation direction opposite to the adjacent rotation shaft 121b for uniform deburring of the object 30.

The additional shaft 122 is equipped with a separate deburring wheel 10 to assist the deburring of the main head portion 121. As shown in FIG. 7A, a plurality of additional shafts 122 are deburred as necessary. It is preferable to install in the (100).

Since the deburring is carried out using the main head portion 121 formed of the parent material, the side portion of the object 30 is removed to some extent, but the burr portion of the side portion is more reliably removed, and the main head portion 121 is further removed. The additional axis 122 is required to deburr the blind spots that are less than).

The additional shaft 122 may be formed to be driven at a predetermined angle in the vertical direction as shown in FIG. 7A, and the brush, that is, the deburring part 12 is rotated in the lateral direction as shown in Type 1 of FIG. 7A. Alternatively, as shown in Type 2 of FIG. 7A, the deburring part 12 may be formed to rotate in the longitudinal direction. The deburring wheel 10 is coupled to the rotating shaft of the additional shaft 122 and may be mounted at least one. The rotation axis is rotated again along the revolution axis of the additional axis 122, the rotation direction of the revolution axis and the rotation axis may be clockwise or counterclockwise.

In this case, when one or more deburring wheels 10 are mounted on the rotating shaft, it is advantageous to reverse the direction of rotation with the adjacent deburring wheels 10 to uniformly remove burrs.

The controller 130 is a part for controlling the driving of the transfer unit 110 and the head unit 120 to deburr the object 30.

The controller 130 may control the deburring automatically according to the type of the object 30 by manual control by an operator or by using software such as a control program.

Specifically, the transfer unit 110 is controlled to transport the object 30 back and forth in the x-axis direction, and the driving of the main head portion 121 and the additional shaft 122 is controlled to burr the object 30. Remove it.

At this time, depending on the size or shape of the object, the additional shaft 122 may be in close contact with the side portion of the object may not be deburring. Therefore, in this case, as shown in FIG. 7B, the additional shaft 122 may be in close contact with the side surface of the object 30 by driving the transfer unit 110 to the left and right.

In addition, if the deburring wheel 10 mounted on the main head portion 121 or the additional shaft 122 shown in FIG. 3 is all set to rotate in one direction (eg, clockwise direction), the feeder 110 may move forward only. If so, the entire object 30 may not be uniformly deburred. Therefore, it is preferable that the entire object 30 is uniformly deburred even when the deburring wheel 10 rotates only in one direction by driving the conveying unit 110 in a reciprocating manner.

In addition, the control unit 130 may control the depth or the rotational speed of the head portion 120 in contact with the mother appropriately according to the type or shape of the object 30, the control unit 110 to control the object 30 ), Further deburring can be continued.

9 is a view showing a state before and after the deburring of the object 30 deburred by the deburring apparatus 100 according to the present invention.

As shown in FIG. 9, when the burr protruding from the object 30 before deburring is removed by the deburring apparatus 100 equipped with the deburring wheel 10 of the present invention formed of a parent material, the object 30 is removed. The whole is uniformly deburred to improve the quality reliability of the object 30.

10 shows experimental values when the same object 30 is deburred by using sandpaper and when deburring by mounting a parent material.

FIG. 10A shows the deburring result when the deburring wheel 10 is formed of sandpaper, and shows a deburred value (R value) according to depth. In the above table, 'N / A' represents a case in which the deburring value could not be measured according to a situation, 'o' represents a case in which the deburring value is too small to be displayed, and 'x' represents no deburring.

In the case of sandpaper, the deburred value (R value) is about 0.8 to 1.2 mm in the vicinity of the surface having a depth of 0 mm, which is sufficiently deburred. It can be seen that (Burr) is hardly removed. Therefore, when deburring using sandpaper, it is difficult to cope with products having various three-dimensional shapes.

FIG. 10B shows the result of deburring the same object 30 as in FIG. 10A according to the present invention. As shown in the table of FIG. 10B, when deburring in accordance with the present invention, the R value from the surface having a depth of 0 mm to a depth of 75 mm appears almost similarly with an R value of 0.1 to 0.5 mm. Therefore, when deburring using the deburring wheel 10 formed of the parent material, it can be seen that the deburring can be performed uniformly without being affected by the depth of the object 30.
