Summary of the Invention

Problems to be Solved by the Invention

[0004] However, even if work standards are set, the quality of the workpiece varies depending on the difference in skills among operators. In response to this, it is also conceivable to level the skills among operators by conducting on-site training, but it takes time and effort to implement on-site training, which may also interfere with manufacturing operations. In addition, although a technique using a rotary polishing device is also known, it has lower freedom than the case of manually removing burrs, so it is difficult when it is desired to remove burrs from multiple directions with respect to the workpiece. Furthermore, work cannot be performed in places where power cannot be secured.

[0005] The object of the present invention is to suppress variations in the quality of workpieces when burrs are removed from workpieces by manual work using a brush. [Means for solving the problem]

[0006] The present invention provides a method for manufacturing a workpiece that achieves the above objective, characterized by holding the workpiece with a sliding member that slides on the surface of a plate material having an opening, pressing the workpiece against the tip of a brush emerging from the opening in the plate material, and sliding the sliding member holding the workpiece against the surface of the plate material to remove burrs from the workpiece. Here, the sliding member may be slid on the surface of the plate material according to a guide portion that guides the sliding of the sliding member. Furthermore, the guide portion may be positioned such that the workpiece does not come into contact with the edge of the opening even when the sliding member is slid. Alternatively, the sliding member holding the workpiece may be rotated relative to the surface of the plate material to change the angle of the workpiece facing the bristles of the brush, thereby causing it to slide relative to the surface of the plate material. Alternatively, the sliding member may be rotated according to the markings attached to the sliding member. Alternatively, the workpiece exposed through the through hole provided in the sliding member may be pressed against the bristles of the brush, causing the sliding member to slide. Furthermore, the deburring device of the present invention, which achieves the above objective, comprises a sliding member that slides on the surface of a plate material having an opening while holding a workpiece, and a fixing means for fixing a brush at a position where the bristles of the brush emerge from the opening of the plate material, wherein the sliding member slides on the surface of the plate material while pressing the workpiece against the bristles of the brush. Here, a guide portion may be further provided to guide the sliding of the sliding member, and the sliding member may be slidable on the surface of the plate material according to the guide portion. Furthermore, the guide portion may be positioned so that the workpiece does not come into contact with the edge of the opening even when the sliding member is slid. Furthermore, the workpiece may be positioned by a positioning mechanism provided on the inner wall of a through hole in the sliding member. Furthermore, the workpiece may be positioned by the step that serves as the positioning mechanism. [Effects of the Invention]

[0007] According to the present invention, when removing burrs from a workpiece by hand using a brush, variations in the quality of the workpiece can be suppressed. [Brief explanation of the drawing]

[Figure 6] This figure shows a specific example of removing burrs formed on a flat, cylindrical workpiece without any steps. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described in detail below with reference to the attached drawings. [Configuration of the deburring device] Figure 1 is a plan view of the deburring device 1. Figure 2(A) is a cross-sectional view of the deburring device 1 (section II-II in Figure 1). Figure 2(B) is a diagram showing an example of the output volume of the brush 30 of the deburring device 1.

[0010] The deburring device 1 used in the manufacture of the workpiece 200 according to this embodiment is a device used to remove burrs from the workpiece 200. The deburring device 1 comprises a plate material 10, a sliding member 20, and a brush 30.

[0011] (plate material) The plate material 10 is a flat plate having an upper surface 11 in the vertical direction, a lower surface 12 in the vertical direction, and an opening 100. The plate material 10 also has a fixing mechanism 101 for fixing the brush 30 to the plate material 10 and a guide member 102 for guiding the sliding of the sliding member 20. The material of the plate material 10 is not particularly limited and can be made of metal, resin, etc.

[0012] The opening 100 is a rounded rectangular hole that penetrates from the upper surface 11 to the lower surface 12 of the plate material 10. A brush 30 is placed in the opening 100 to press against burrs formed on the surface of the workpiece 200. The shape of the opening 100 is not limited to the shape shown in Figure 1, as long as it is large enough to accommodate the brush 30, and can be shaped according to the shape of the bristles 31 of the brush 30. Similarly, the size of the opening 100 is not limited to the size shown in Figure 1, as long as it is large enough to accommodate the bristles 31 of the brush 30, and can be sized according to the size of the bristles 31 of the brush 30.

[0013] The fixing mechanism 101 is a mechanism for fixing the brush 30 to the lower surface 12 side of the plate material 10, and is composed of a belt 112 inserted into six through holes 111 penetrating the upper surface 11 and the lower surface 12 of the plate material 10. The fixing mechanism 101 fixes the handle 32 of the brush 30 to the lower surface 12 of the plate material 10 by the belt 112. When fixing the handle 32 of the brush 30, the fixing mechanism 101 fixes it so that the bristles 31 of the brush 30 are arranged in the opening 100 of the plate material 10. Therefore, the fixing mechanism 101 functions as a positioning mechanism for determining the horizontal position and the vertical position of the bristles 31 of the brush 30.

[0014] The guide member 102 is a flat plate having an upper surface 121 on the upper side in the vertical direction, a lower surface 122 on the lower side in the vertical direction, and an opening 120, and is fixed so that the lower surface 122 and the upper surface 11 of the plate material 10 face each other. The method of fixing the guide member 102 to the plate material 10 is not particularly limited, and it is fixed by methods such as screwing, welding, and adhesion. In this embodiment, it is fixed using four sets of screws 141 and nuts 142. The guide member 102 is arranged at a position where the opening 120 surrounds the entire opening 100 of the plate material 10. The opening 120 is a round-cornered square hole provided so as to penetrate from the upper surface 121 to the lower surface 122 of the guide member 102. The edge of the opening 120 constitutes a guide portion 123 that defines the range in which the sliding member 20 slides.

[0015] The guide member 102 is arranged at a position where the workpiece 200 does not contact the edge 131 of the opening 100 even when the sliding member 20 slides on the upper surface 11 of the plate material 10. Thereby, the range in which the sliding member 20 slides and the range in which the workpiece 200 held by the sliding member 20 moves through the opening 100 are defined by the guide portion 123. Details of the positional relationship among the workpiece 200, the opening 100, the sliding member 20, and the guide portion 123 will be described later with reference to FIG. 3.

[0016] (Sliding member) The sliding member 20 is a thin, cylindrical member that can slide along the upper surface 11 of the plate material 10 while holding the workpiece 200 to be deburred. The material of the sliding member 20 is not particularly limited and can be made of metal, resin, etc. The sliding member 20 is slid by the operator's manual operation. The sliding member 20 has an upper surface 21 on the upper side in the vertical direction and a lower surface 22 on the lower side in the vertical direction, which is the sliding surface. The sliding member 20 also has a workpiece holding hole 23, which is a through hole that penetrates the upper surface 21 and the lower surface 22, and holds the workpiece 200 while exposing a part of the workpiece 200 to the lower side. A positioning mechanism for positioning the workpiece 200 is provided in the workpiece holding hole 23. A specific example of the positioning mechanism provided in the workpiece holding hole 23 will be described later with reference to Figure 3.

[0017] The sliding member 20 allows the upper surface 11 of the plate material 10 to rotate circumferentially while holding the workpiece 200. The sliding member 20 is rotated by the operator's manual operation. The upper surface 21 of the sliding member 20 is marked with three markers 24 that allow the rotation of the upper surface 11 of the plate material 10 to be tracked. The markers 24 are placed at predetermined angles. For example, markers 24 are placed at 90 degrees, 60 degrees, 45 degrees, etc. In this embodiment, markers 24 are placed at 90-degree intervals. The markers 24 can be, for example, printed or engraved, or cut through. In this embodiment, the markers 24 are cut through. Cutting through the markers 24 increases the visibility of the brush 30. The number of markers 24 is not limited to three. Any number of markers 24 may be placed as long as they allow the rotation status of the sliding member 20 to be tracked.

[0018] (Brush) The brush 30 is a brush having bristles 31 and a handle 32, and removes burrs formed on the surface of the workpiece 200 by brushing. The bristles 31 are positioned in the opening 100 of the plate material 10 and remove burrs formed on the surface of the workpiece 200 as it moves through the opening 100 in accordance with the movement of the sliding member 20. The material of the bristles 31 is not particularly limited and is selected according to the material of the workpiece 200 and the nature of the burrs formed on the surface of the workpiece 200. For example, resin or metallic bristles can be selected. The handle 32 is the part that is fixed to the plate material 10 by the fixing mechanism 101 of the plate material 10, and the entire brush 30 is fixed when the handle 32 is fixed to the plate material 10, and at the same time the position of the bristles 31 is determined. The material of the handle 32 is also not particularly limited and is selected according to example, resin or metallic handle can be selected.

[0019] As described above, the horizontal and vertical positions of the bristles 31 of the brush 30 are positioned by the fixing mechanism 101. For example, as shown in Figure 2(B), the horizontal position of the bristles 31 is located at the opening 100 of the plate material 10, and the vertical position of the bristles 31 is positioned so that the end 311 of the bristles 31 is at the height of the upper surface 121 of the guide member 102. With the workpiece 200 in this position, when the sliding member 20 holding the workpiece 200 is placed at the opening 120 of the guide member 102, as shown in Figure 2(A), a portion of the workpiece 200 exposed below the sliding member 20 comes into contact with the bristles 31.

[0020] (others) At each of the four corners of the deburring device 1, there are two sets of screws 151 and nuts 152 used for fixing the deburring device 1 in place.

[0021] Figure 3(A) is an enlarged cross-sectional view (an enlarged view of the II-II cross-sectional view in Figure 1) showing how a portion of the workpiece 200 exposed below the sliding member 20 is in contact with the bristles 31 of the brush 30. Figure 3(B) is an enlarged cross-sectional view (an enlarged view of the III-III cross-sectional view in Figure 1) showing how a portion of the workpiece 200 exposed below the sliding member 20 is in contact with the bristles 31. The workpiece 200 according to this embodiment is a workpiece that has a step formed on it by machining. The workpiece 200 has a large diameter portion 210 and a small diameter portion 220 formed on it by machining. During machining, a burr 230 is formed on the end of the small diameter portion 220, either partially or almost around its circumference.

[0022] The workpiece holding hole 23 of the sliding member 20 is shaped to match the shape of the workpiece 200. Specifically, a step 231 is provided on the inner wall of the workpiece holding hole 23 as a positioning mechanism for positioning the workpiece 200. As described above, the workpiece 200 has a step, and a burr 230 is formed at the end of the small-diameter portion 220. For this reason, the workpiece 200 is inserted into the workpiece holding hole 23 so that the part with the burr 230 is facing downwards. Then, the end 211 of the large-diameter portion 210 that makes up the workpiece 200 inserted into the workpiece holding hole 23 abuts against the step 231 provided on the inner wall of the workpiece holding hole 23. This positions the workpiece 200 in the vertical direction.

[0023] As described above, the guide member 102 is positioned so that even when the sliding member 20 slides along the upper surface 11 of the plate material 10, the workpiece 200 does not come into contact with the edge 131 of the opening 100. Specifically, for example, as shown in Figures 3(A) and (B), the guide member 123 is positioned such that the distance D1 between the sliding member 20 and the guide member 123 is shorter than the distance D2 between the workpiece 200 and the edge 131 of the opening 100.

[0024] In this way, by arranging the components so that distance D1 < distance D2 on both the II-II cross section side and the III-III cross section side of Figure 1, it is prevented that the workpiece 200 extends beyond the bristles 31 of the brush 30 and comes into contact with the plate material 10. This reduces the chance of the workpiece 200 being damaged. Furthermore, on the II-II cross section side of Figure 1, the range of movement of the workpiece 200 is defined by the length of distance D1, so the time and distance over which the workpiece 200 contacts the bristles 31 of the brush 30 become constant.

[0025] [Deburring procedure] Figure 4 shows the procedure for removing burrs 230 formed on a workpiece 200 using the deburring device 1. As shown in Figures 3(A) and (B) above, a burr 230 is formed around the end of the workpiece 200, extending almost all the way around. Therefore, when the operator removes the burr using the deburring device 1, the operator rotates the sliding member 20, which holds the workpiece 200, relative to the upper surface 11 of the plate material 10, thereby changing the angle of the workpiece 200 facing the tips of the bristles 31 of the brush 30.

[0026] Specifically, the operator removes burrs by alternately performing the following actions with respect to the sliding member 20 holding the workpiece 200: pressing the workpiece 200 from top to bottom while sliding it back and forth horizontally between the first and second sides according to the guide portion 123, and rotating it 90 degrees to the right in the circumferential direction. When the operator rotates the sliding member 20 holding the workpiece 200 90 degrees to the right in the circumferential direction, the operator rotates the sliding member 20 according to the mark 24 provided on the upper surface 21 of the sliding member 20.

[0027] For example, as shown in Figure 4, the burrs in the 0-degree direction are removed by sliding the sliding member 20 back and forth horizontally between the first and second sides (1st time) (STEP 1), and the orientation of the sliding member 20 is changed by rotating it 90 degrees to the right in the circumferential direction (1st time) (STEP 2). Next, the burrs in the 90-degree direction are removed by sliding the sliding member 20 back and forth horizontally (2nd time) (STEP 3), and the orientation of the sliding member 20 is changed by rotating it another 90 degrees to the right in the circumferential direction (2nd time) (STEP 4).

[0028] Next, the sliding member 20 is moved back and forth horizontally (3rd time) to remove the burrs in the 180-degree direction (STEP 5), and the sliding member 20 is rotated another 90 degrees to the right in the circumferential direction (3rd time) to change its orientation (STEP 6). Next, the sliding member 20 is moved back and forth horizontally (4th time) to remove the burrs in the 270-degree direction (STEP 7), and the workpiece 200 is removed from the sliding member 20 (STEP 8). In other words, in STEPs 1 to 8, the sliding member 20 is moved back and forth horizontally and rotated 90 degrees to the right in the circumferential direction alternately. This ensures that the brush 30 uniformly brushes the burrs formed around the edge of the workpiece 200.

[0029] [Example of deburring device usage] Figure 5 shows an example of the use of the deburring device 1. The deburring device 1 can be used by placing it inside the case 50, for example, as shown in Figure 5. The operator 40 can remove burrs formed on the surface of the workpiece held by the sliding member 20 by alternately sliding and rotating the sliding member 20 of the deburring device 1, which is placed inside the case 50. The removed burrs fall downward and accumulate inside the case 50, thus preventing them from scattering.

[0030] In summary, the method for manufacturing a workpiece to which the present invention applies only needs to have the following configuration, and various embodiments can be adopted. In other words, the method for manufacturing a workpiece to which the present invention applies (for example, workpiece 200 in Figure 3(A), workpiece 300 in Figure 6) is characterized by holding the workpiece with a sliding member 20 that slides on the surface of a plate material 10 having an opening 100 (for example, the upper surface 11 in Figure 1), pressing the workpiece against the bristles of a brush 30 that emerges from the opening 100 of the plate material 10 (for example, the bristles 31 in Figure 3(A)), and sliding the sliding member 20 holding the workpiece against the surface of the plate material 10 to remove burrs 230 from the workpiece.

[0031] A workpiece is held by a sliding member 20 that slides on the surface of a plate material 10 having an opening 100. The workpiece is pressed against the bristles of a brush 30 that emerges from the opening 100, and the burrs 230 of the workpiece are removed by sliding the sliding member 20, which holds the workpiece, against the surface of the plate material 10. This makes it possible to uniformize the force and angle of the brush 30 pressed against the workpiece. As a result, when the removal of burrs 230 from a workpiece is performed manually with a brush 30, variations in the quality of the workpiece can be suppressed. In addition, the opportunities for the worker to touch the brush 30 are reduced, so for example, a resin finger cot worn on the worker's finger may be scraped by the brush 30, and the resulting contamination of the workpiece can be prevented. Furthermore, since the plate material 10 acts as a lid, the scattering of burrs 230 removed by the brush 30 is prevented.

[0032] Here, the sliding member 20 may be slid on the surface of the plate material 10 according to the guide portion 123 that guides the sliding of the sliding member 20. As a result, the guide portion 123 guides the sliding of the sliding member 20, preventing the sliding member 20 from sliding in a range unintended by the operator.

[0033] Furthermore, the guide portion 123 may be positioned so that the workpiece does not come into contact with the edge 131 of the opening 100 even when the sliding member 20 is slid. The guide portion 123 is positioned so that the workpiece does not come into contact with the edge 131 of the opening 100 even when the sliding member 20 is slid. This prevents damage to the workpiece caused by contact between the workpiece and the edge 131 of the opening 100.

[0034] Alternatively, the sliding member 20 holding the workpiece may be rotated relative to the surface of the plate material 10 to change the angle of the workpiece facing the bristles of the brush 30, thereby causing it to slide relative to the surface of the plate material 10. By rotating the sliding member 20, which holds the workpiece, relative to the surface of the plate material 10, the angle of the workpiece relative to the bristles of the brush 30 is changed. This enables uniform brushing of the burrs 230 of the workpiece from multiple directions.

[0035] Alternatively, the sliding member 20 may be rotated according to the mark 24 attached to the sliding member 20. The sliding member 20 is rotated according to the mark 24 attached to the sliding member 20. This allows the worker to immediately understand that the sliding member 20 has been rotated, thereby improving work accuracy and efficiency.

[0036] Alternatively, the workpiece exposed through a through hole in the sliding member 20 (for example, the workpiece holding hole 23 in Figures 3(A) and (B)) may be pressed against the bristles of the brush 30, causing the sliding member 20 to slide. This enables uniform brushing of the portion of the sliding member 20 that is exposed from the sliding surface (for example, the lower surface 22 in Figure 2(A)).

[0037] Furthermore, the deburring device 1 of the present invention, which achieves the above objectives, comprises a sliding member 20 that slides on the surface of a plate material 10 having an opening 100 while holding a workpiece, and a fixing means (for example, the fixing mechanism 101 in Figure 1) that fixes the brush 30 at a position where the bristles of the brush 30 emerge from the opening 100 of the plate material 10, wherein the sliding member 20 slides against the surface of the plate material 10 (for example, the upper surface 11 in Figure 1) while pressing the workpiece against the bristles of the brush 30, and is characterized by being a deburring device. A workpiece is held by a sliding member 20 that slides on the surface of a plate material 10 having an opening 100. The workpiece is pressed against the bristles of a brush 30 that emerges from the opening 100, and the burrs 230 of the workpiece are removed by sliding the sliding member 20, which holds the workpiece, against the surface of the plate material 10. This makes it possible to uniformize the force and angle of the brush 30 pressed against the workpiece. As a result, when the removal of burrs 230 from a workpiece is performed manually with a brush 30, variations in the quality of the workpiece can be suppressed. In addition, the opportunities for the worker to touch the brush 30 are reduced, so for example, a resin finger cot worn on the worker's finger may be scraped by the brush 30, and the resulting contamination of the workpiece can be prevented. Furthermore, since the plate material 10 acts as a lid, the scattering of burrs 230 removed by the brush 30 is prevented.

[0038] Here, a guide portion 123 may be further provided to guide the sliding of the sliding member 20, and the sliding member 20 may be slidable on the surface of the plate material 10 according to the guide portion 123. As a result, the guide portion 123 guides the sliding of the sliding member 20, preventing the sliding member 20 from sliding in a range unintended by the operator.

[0039] Furthermore, the guide portion 123 may be positioned so that the workpiece does not come into contact with the edge 131 of the opening 100 even when the sliding member 20 is slid. The guide portion 123 is positioned so that the workpiece does not come into contact with the edge 131 of the opening 100 even when the sliding member 20 is slid. This prevents damage to the workpiece caused by contact between the workpiece and the edge 131 of the opening 100.

[0040] Furthermore, the workpiece may be positioned by a positioning mechanism provided on the inner wall of a through hole (for example, the workpiece holding hole 23 in Figures 3(A) and (B)) provided in the sliding member 20. The workpiece is positioned by a positioning mechanism provided on the inner wall of the through-hole. This allows for uniformity in the portion of the sliding member 20 that is exposed from the sliding surface. As a result, uniform brushing becomes possible.

[0041] Furthermore, the workpiece may be positioned by a step 231 which serves as a positioning mechanism. A step 231 is provided on the inner wall of the through-hole as a positioning mechanism. This allows for uniformity in the portion of the sliding member 20 that is exposed from the sliding surface. This enables uniform brushing.

[0042] [Other embodiments] Although this embodiment has been described above, the technical scope of the present invention is not limited to the above embodiment. Various modifications and substitutions of configurations that do not depart from the technical concept of the present invention are included in the present invention. In the above embodiment, for example, as shown in Figures 3(A) and (B), a step 231, which serves as a positioning mechanism, is provided on the inner wall of the workpiece holding hole 23 of the sliding member 20 to position the workpiece 200. However, this configuration is merely one example of a configuration when the shape of the workpiece is a cylindrical shape with a step. For example, when the shape of the workpiece is a flat cylindrical shape without a step, a clamping function may be provided in the workpiece holding hole 23 of the sliding member 20 so that the workpiece can be fixed in the workpiece holding hole 23. Specifically, for example, a scroll chuck may be used to fix the workpiece in the workpiece holding hole 23.

[0043] Figure 6 shows a specific example of removing burrs formed on a flat, cylindrical workpiece 300 without any steps. As shown in Figure 6, for example, the operator first inserts a flat, cylindrical workpiece 300 without any steps into the workpiece holding hole 23 of the sliding member 20 (STEP 1). Next, the operator pushes the workpiece 300 so that a portion of it is exposed downwards from the sliding member 20 (STEP 2). Then, the clamping function of the workpiece holding hole 23 fixes the workpiece 300 inside the workpiece holding hole 23 (STEP 3). This makes it possible to position the workpiece 300 with a portion of it pressed into the bristles 31 of the brush 30 placed in the opening 100 of the plate material 10.

[0044] Furthermore, in the above-described embodiment, the shape of the workpiece to be deburred is cylindrical, but it is not limited to this. For example, it may be a rectangular prism shape or the like. In other words, the shape of the workpiece does not matter as long as it can be fixed in the workpiece holding hole 23 provided in the sliding member 20 of the deburring device 1.

[0045] Furthermore, although the fixed brush 30 is configured not to move in the above-described embodiment, the system is not limited to this configuration. For example, the system may have a mechanism to vibrate the brush 30. This makes it easier to remove burrs. [Explanation of symbols]
