Description

  The present invention relates to a technical field of a deburring brush for scraping fine projection pieces generated at an edge after processing in machining of metal or woodwork, and particularly to a constituent member for forming a cylindrical brush having an external appearance.

As a brush-like polishing tool, there is a tool in which a polishing cloth or polishing brush is attached to the outer periphery to form a disk shape, and this disk-like polishing brush is coaxially laminated at a predetermined pitch (gap) to form a roll shape. Widely used in the past.
However, in such a tool, the polishing streaks and the non-uniformity of the polishing surface are generated due to the material and mounting strength of the brush bristle material, and the presence of the brush mounting pitch.

  As a means for improving the polishing quality by eliminating this, a technical configuration in which the polishing cloth is disposed in a spiral shape along the rotation axis is already known, and various applications have been made in the past (for example, patents). References 1, 2, and 3).

  Further, as an invention for eliminating the complexity of spiral winding a continuous long continuous polishing cloth around a core material, a polishing wheel formed in a spiral shape by shifting the polishing cloth one layer at a time An invention is disclosed in which a large number of layers are laminated while matching lines to form a series of spiral abrasive cloth layers that are continuous around a rotation axis (see, for example, Patent Documents 4 and 5).

JP-A-6-155315 JP-A-1994-155315 JP 2004-195171 A JP 2008-142792 A JP 2000-326239 A Japanese Utility Model Publication No. 63-151272

  However, in the brushes disclosed in Patent Documents 1, 2, and 3, the technical effect by the spiral arrangement of the abrasive cloth paper has already been recognized. Since a long abrasive cloth paper or brush bundling material made of a single continuous material is spirally attached to a shaft member to be wrapped around the shaft, the operation is very complicated. For this reason, it is difficult to maintain a uniform processing accuracy of continuous abrasive cloth and to maintain the quality of the polishing brush after installation, and there are problems in decreasing productivity and product cost. In order to compensate for such variations in brush products, the current situation is that the polishing object and the polishing brush in the polishing machine are swung or peristally moved to maintain the uniformity of the polishing process. .

  In an actual deburring process, a polishing cloth brush for surface treatment is applied to a rectangular (strip or strip) polishing cloth with a narrow width and a high aspect ratio in the radial direction around the disk for rotating shaft ring. The mainstream configuration is a configuration in which a large number of the same are stacked on the same axis.

  In addition, the brushes disclosed in Patent Documents 4 and 5 are formed as a series of continuous spirals by overlapping a plurality of spirally arranged sheets for each layer, but there are also gaps in the upper and lower layers. It was not densely laminated. The appearance structure was a roll having a cylindrical peripheral surface. Since this structure is intended for grinding and polishing, it was originally intended to treat the surface as a processing target and polish the surface smoothly. This is difficult to remove burrs, which are extra protruding strips formed at the cutting edge or ridge during metal working. In other words, since the burr protruding direction varies, only the burr cannot be removed sufficiently and effectively by the contact polishing of the cylindrical peripheral surface as in the above disclosed invention. Rather, due to the contact with the circumferential surface, the edges and corners where burrs are not generated (or after burr cutting) are unnecessarily polished, and there is a possibility that the processing accuracy may be distorted. Removing only burrs is important in terms of improving product accuracy.

  Accordingly, the present invention has been made paying attention to the above-mentioned problem, and by removing strips (or strips) of abrasive cloth continuously arranged in a spiral shape, it is possible to effectively remove only burrs. It is intended to provide an abrasive cloth holder for an intended deburring brush, a brush component board for a deburring brush using the same, and an invention of three categories of deburring brushes laminated with the same.

  In order to solve the above problems, the invention specified as the third category according to the present invention is configured as follows.

  An abrasive cloth paper holder for a deburring brush according to one aspect of the present invention has a thickness that exceeds the thickness of the abrasive cloth paper, and is used to wrap around the rotation shaft of the rotation driving means at the center. Spiral through a circular or regular polygonal disk-shaped core body having a through-hole and one or more fault sections shifted in the thrust direction by the thickness distance of the core body around the outer periphery of the core body The flange arranged in a shape and either the upper surface side or the lower surface side of the flange are specified as the mounting surface of the polishing cloth.

Moreover, although the said tomographic part is normally provided in one place of the outer periphery of a core body, you may provide in two or more places if needed. The arrangement in this case is preferably arranged at equal intervals around the outer periphery. For example, in a two-position arrangement, a facing position rotated by 180 degrees is preferable.
Here, the attachment surface to which the abrasive cloth paper is attached specifies any one of the upper and lower surfaces of the flange. In addition, the up-down direction is used as a direction along the stacking direction described later or the thrust direction.

  In addition, as a component of the invention to be described later, the core body has a core body as necessary as a benefit when the plural through-holes are made to coincide with each other and are stacked (stacked with each board surface in contact with each other). Positioning means may be provided on one side or both sides of the board surface. The form is appropriate, but for example, it may be an uneven structure having a position and shape that can be adapted when the board surface is brought into contact, and further, as a fitting structure with a click feeling to be fixed and detached Also good.

Next, in the brush constituting board for a deburring brush according to the second invention of the present application, the longitudinal direction of the large number of strips of abrasive cloth formed in a strip shape on the mounting surface of the abrasive cloth holder is described above. The core body is configured to be attached in the radial direction and over the entire circumference thereof. The abrasive cloth to be attached here may have a single strip shape, but it is preferable that each abrasive cloth is arranged in parallel and has one end side connected to each other. Thereby, the attachment over the perimeter of the attachment surface around a core body can be performed rapidly.
The strip-shaped abrasive cloth includes a linear material (or strip-like material) such as a string in addition to a high aspect ratio rectangle or parallelogram strip.

  In addition, the meaning of the warm pattern is not specified from the manufacturing process in which a large number of single abrasive cloths are arranged in parallel and connected at one end thereof to form a warm pattern, and includes a warm pattern as an appearance. It is a concept. For example, it includes a step of cutting a belt-like or rectangular sheet-like polishing cloth with a predetermined width from the short side direction to leave a predetermined width in the longitudinal direction and making it warm.

  Next, the brush for deburring that is the third invention according to the present application is configured by using the brush constituting board that is the second invention that is configured by using the abrasive cloth paper holder of the first invention, and It is configured as follows.

  A large number of the above-described brush constituting boards are laminated so that the through holes and the tomographic portions coincide with each other, and the appearance is configured in a substantially cylindrical shape. The width of the brush when attached to the rotating shaft is specified by the number of layers. Moreover, in the lamination | stacking of the said brush component board, it is good also as a structure which applies the said positioning means.

The invention according to the present application configured as described above has the following effects.
That is, in the polishing cloth holder for the deburring brush, since the thickness of the core body exceeds the thickness of the polishing cloth, the core body with the polishing cloth attached. When these are stacked, an appropriate gap is formed between the attachment surfaces of the upper and lower layers.

  In addition, since the abrasive cloth is attached to the mounting surface of the flange that is spirally disposed as an integral molding or as a separate member fixed around the outer periphery of the core body, the abrasive cloth is spirally wound around the core body. A brush construction board can be formed. By laminating an appropriate number of this brush component board, the abrasive cloth that is wrapped around the core body and attached individually is as if a series of abrasive cloth is spiraled with the fault section as the connection point. It can be formed in the appearance of being wound.

  And when the thickness of each laminated | stacked core body is the same, the spiral arrangement | positioning of abrasive cloth paper becomes a spiral of equal pitch, and strip-like (including linear form) abrasive cloth paper adjacent to the up-down direction is Since there is a gap corresponding to the thickness of the core body, the core body can be bent, bent, or bent (hereinafter referred to as “bend” or the like) independently and freely. This bending in the free direction can be brought into contact with the burr to be ground with the optimum grinding force and grinding direction, and only unnecessary burrs are appropriately removed without damaging the processing part other than the burr. There is an effect that can be.

A first embodiment (hereinafter referred to as “embodiment 1”) for carrying out the present invention will be described below with reference to FIGS.
Reference numeral 1 denotes an abrasive cloth paper holder 1 according to the first embodiment, which will be described in detail with reference to FIGS. 1 to 3. Here, the abrasive cloth paper holder 1 has a specification for attaching a single line of abrasive cloth paper 3 (about 360 degrees) as will be described later, and this specification form is abbreviated as “one line holder 1”. Used for the following explanation.

  The one-piece holder 1 has a disk-shaped core body 10 formed with a circular plane in the vertical direction (for the sake of convenience in accordance with the drawings) as a base, and a flange 15 extending in the radial direction with a predetermined width is integrally formed on the outer periphery thereof. Is formed.

  A deburring brush (hereinafter abbreviated as “brush”) 4, which will be described later, is provided at the center of a circular disk surface 11 (“disk surface” in the present embodiment) of the core body 10 as a rotational drive means (not shown). A through hole 12 is formed to be mounted on the rotary shaft 5. Further, the core body 10 has a fitting recess 13 as a positioning means on the upper surface of the symmetrical position with the through-hole 12 interposed therebetween, and a fitting protrusion 14 to be fitted to the corresponding position on the opposite side of the lower surface. Is formed.

  In the flange 15, a tomographic part 16 is formed which is moved (or sheared) in a staggered manner in the thrust direction (thickness direction or vertical direction in the drawing) by the thickness distance t of the core body 10 at one location. ing. This tomographic section 16 is used as a boundary to make one turn in a spiral shape (inclination along the circumferential direction). By this helical configuration, a flange surface (surface in the vertical direction of the flange 15) having a gradient along the circumference by a thickness distance t from one tomographic surface 16a of the tomographic part 16 to the other tomographic surface 16b is formed. doing. This flange surface is used as a mounting surface 15s of the polishing cloth 3 to be described later. The mounting surface 15s may be any surface side of the flange 15 in the vertical direction.

  The material of the core body 10 and the flange 15 may be metal or nonmetal, but is preferably formed of a synthetic resin material for the purpose of formability and weight reduction. As the shape, for example, the diameter of the core body 10 is set to about 100 to 180 mm, and the thickness is set to about 6 to 12 mm.

  In addition, although the core body 10 used in the present embodiment has a disk shape, the present invention is not limited to this, and is not limited to this, and is a regular polygon that is close to a circle (for example, a regular octagon, a regular dodecagon). Or a regular hexagon. In addition, the positioning means is intended to ensure that the tomographic sections 16 quickly coincide with each other at the time of sequential lamination and also to secure a bonding force between the upper and lower layers. However, this positioning means is not an indispensable component, and positioning can also be performed by adapting the tomographic planes 16a and 16b to which the tomographic section 16 is displaced.

  Next, reference numeral 2 denotes the brush component board 2, which will be described with reference to FIGS. The brush construction board 2 is constructed by attaching the polishing cloth 3 to the attachment surface 15 s of the single-line holder 1 described above over one turn. The appearance is a disk-shaped brush.

  The abrasive cloth 3 to be attached has a strip shape (strip shape) having a small width with respect to the length, and a large number of these sheets in the radial direction (or radial direction) from the outer periphery of the core body 10 on substantially the same plane as the disk surface. It is attached so as to overhang. The overhanging length of the strip-like material is appropriate, but is set to about 30 to 100 mm in this embodiment. The abrasive cloth paper 3 used in the present embodiment is cut and processed from a general water-resistant or non-water-resistant sheet-like abrasive cloth paper. The raw material of this abrasive cloth is usually known silicon carbide, aluminum oxide, emery, garnet and the like.

  The polishing cloth 3 used in this example is a rectangular sheet (not shown), which is a linear sheet with a predetermined width (several millimeters) left in the longitudinal direction at the midpoint of the short distance. One part is connected by making the part into a crease part, cutting at a predetermined interval (for example, about 3 to 7 mm) from both side edges in the longitudinal direction, and folding into two at the crease part left at the intermediate point. It is formed in a warm and warm shape. And this warm-up-like polishing cloth 3 is fixed to the mounting surface 15s by using an adhesive or a staple (not shown). In addition, by making this polishing cloth 3 warm, it is possible to improve the mounting workability and ensure the reliability.

  As described above, by attaching the abrasive cloth paper 3 to the attachment surface 15a of the flange 15 with respect to the core body 10, the abrasive cloth paper 3 is formed as a one-turn spiral with the thickness distance of the core body 10 as one pitch. They are arranged at the same length and at equal intervals over the entire circumference of ten.

  Reference numeral 4 denotes a deburring brush 4 (hereinafter abbreviated as “brush”), which will be described with reference to FIG.

  The brush 4 has a cylindrical appearance (roll shape) by laminating a necessary number of the above-described brush component boards 2. In this lamination, the through holes 12 formed in the disk surface 11 of the core body 10 are made to coincide with each other and the disk surface 11 is brought into contact with each other. At this time, the fitting recess 13 and the fitting protrusion 14 By fitting the core members 10 to each other, it is possible to align the core bodies 10 with each other and the tomographic portions 16 of each layer on a straight line in the vertical direction.

  More specifically, as shown in FIGS. 6A and 6B, the upper layer and the lower layer of the tomographic section 16 composed of the tomographic planes shifted in the vertical direction are matched, and one side of the tomographic section 16 located in the lower layer The tomographic plane 16a and the tomographic plane 16b on the other side of the tomographic section 16 located in the upper layer are configured to face each other in the same plane. As a result, the attachment surface 15s of the lower flange 15 is connected to the attachment surface 15s of the upper flange 15 through the fault portion 16 on the substantially same plane, and is individually attached to each of the upper and lower attachment surfaces 15s, 15s. The attached abrasive cloths 3 and 3 have the appearance of a continuous continuous abrasive cloth 3 without any interruption at the tomographic portion 16 in appearance, and have the same effect as a functionally continuous member.

  By laminating a large number of brush constituting panels 2 with the core body 10 laminated in this way as a core material, it is as if a continuous series of abrasive cloths 3 are arranged at a constant pitch around the rotation axis and between the pitches. It is possible to form a roll-like brush 4 that is continuously wound in a spiral manner while providing a gap. The axial width (or roll width) of the brush 4 is appropriately set depending on the number of layers of the brush component board 2.

  Moreover, since this lamination is fixed and held by the close fitting of the fitting concave portion 13 and the convex portion 14, the number of lamination of the brush component board 2 can be easily changed. Moreover, only the brush component board 2 can be replaced for partial wear.

  Next, a second embodiment (hereinafter referred to as “embodiment 2”) for carrying out the present invention will be described with reference to FIGS. In this embodiment, the one-line holder 1 has a specification in which a single turn is attached with a series of abrasive cloth papers 3, whereas a series of abrasive cloth papers 3 are attached individually every half turn (about 180 degrees). It is a specification. This specification form is abbreviated as “two-row holder 6” and used in the following description. In the description of the second embodiment, the constituent elements of the first and second embodiments are the same except for the number of tomographic sections 16, and thus the same reference numerals are given and detailed description thereof is omitted.

  The illustrated display 6 is a two-strip holder 6 according to the second embodiment. The feature of the two-strip holder 6 is that the above-described tomographic part 16 is formed at two locations on the outer periphery facing each other. Thereby, flanges (hereinafter referred to as “two-row flanges”) 61 and 61 corresponding to the two-rows having a spiral gradient along the circumferential direction of the two-row core body (hereinafter, “two-row core body”) 60 are formed. Yes. The double flange 61 is configured as independent for each half of the outer periphery of the double core body 60.

  Independent (or discontinuous) mounting surfaces 61s and 61s are formed on the vertical surfaces of the two flanges 61 and 61, respectively. Since the double flange 61 for each half circumference is configured to substantially coincide with the thickness distance t of the double core body 60, the gradient amount (vertical component of the gradient) along the circumference for each mounting surface 61s is two. The thickness distance t of the core body 60 is obtained.

  As in the first embodiment, the double core body 60 configured as described above is provided with the double-sided brush composition board 8 by attaching the polishing cloth 7 for each half circumference to the respective attachment surfaces 61s, 61s for each half circumference. Is forming. Then, a large number of the brush constituting boards 8 are laminated in the same manner as in the first embodiment, and the continuous abrasive cloth 7 is formed at a constant pitch around the rotation axis with a predetermined gap between the pitches. A series of continuous double spirals are formed while being provided, and a roll (or cylindrical) deburring brush 9 is formed by this lamination.

  In the brush component board 8 of the second embodiment, a spiral of one pitch is formed every half circumference. Therefore, when the thickness of the double core body 60 is the same as that of the first embodiment, the brush 9 after lamination is formed. As for the external appearance, the helical pitch is 1/2 pitch. Moreover, when the thickness of the double core body 60 is twice that of the first embodiment, spirals having the same pitch can be formed. Therefore, when the double-row core body 60 having two opposing tomographic sections 16 as in the second embodiment is formed with a thickness twice that of the single-core core body 10, the brush constituting board 8 The deburring brush having the same roll width can be formed by halving the number of the parts, and the number of parts can be reduced.
