Description

  The present invention relates to a washer polishing device for polishing in order to remove rust and the like adhering to the front and back surfaces of a washer.

  When the machine is overhauled, the anti-seize agent and rust adhere to the washer used to assemble the machine. Therefore, when reassembling a machine that has been disassembled and inspected to its original state, it is necessary to remove the anti-seizing agent and rust attached to the washer. At this time, the washer is polished. Conventionally, this washer polishing operation is a manual operation in which an operator uses a buff or a wire brush. However, when a polishing operation is performed using such a buff or grinder, polished deposits, wire brush fragments, small-diameter washers, and the like may scatter. In addition, since the operator has to fix the washer, the operator may contact the buff or the wire brush. As described above, when the washer polishing operation is performed manually, it is dangerous for the operator.

On the other hand, it has a washer fixing chuck for fixing a washer that slides in the vertical direction, a polishing foil brush provided on a rotary shaft that moves up and down facing the washer fixing chuck, and a transparent plate that covers the working part. A washer polishing device has been proposed (see Patent Document 1). According to this washer polishing device, the washer is installed on the washer fixing chuck and fixed with the gripping claws. Then, the washer is polished by pressing and rotating the foil brush on the surface of the washer fixed to the washer fixing chuck. At this time, since the transparent plate is provided around, it is possible to prevent the deposits and the broken pieces of the wire brush from being scattered during the polishing operation, and the operator can check the state of the washer.

A first embodiment of the present invention will be described with reference to the drawings. FIG.1 and FIG.2 is a schematic block diagram of the washer polisher of this embodiment. FIG. 1 is a perspective view from the side, and FIG. 2 is a cross-sectional view.

  As shown in FIG. 1 or FIG. 2, the washer polishing apparatus of this embodiment includes a transport disk 2 on which the washer 1 is installed, wire brushes 3 a and 3 b and a flat brush 3 c for polishing the washer 1, and a wire brush. Grinders 4a and 4b for rotating 3a and 3b, support plates 5a and 5b for positioning the grinders 4a and 4b, and positioning of the wire brushes 3a and 3b of the grinders 4a and 4b by setting the angles of the support plates 5a and 5b An adjustment handle 6 for performing the above, a protective cover 7 covering the periphery of the wire brushes 3a and 3b and having a transparent protective plate on the side surface and the upper surface, a motor 8 for generating power for rotating the transport disk 2, and a motor 8 A belt 9 for transmitting the power from the conveyor disk 2 to the shaft 2a, and a discharge guide for removing the polished washer 1 from the conveyor disk 2 and discharging it. It includes a 10, a.

  This washer polishing device is installed so that the rotation direction of the wire brushes 3a, 3b by the grinders 4a, 4b and the rotation direction of the transport disk 2 are perpendicular to each other, and the wire brushes 3a, 3b are directly above the shaft 2a of the transport disk 2. The conveying disk 2 is installed at a position between the wire brushes 3a and 3b so as to sandwich the washer 1 positioned therebetween. Further, the flat brush 3c is installed at a position between the wire brushes 3a and 3b so as to be positioned immediately above the washer 1 positioned immediately above the shaft 2a of the transport disk 2. Accordingly, the polishing surfaces of the outer peripheral surfaces of the wire brushes 3 a and 3 b are in contact with both end surfaces of the washer 1, and the polishing surface of the flat brush 3 c is in contact with the outer peripheral surface of the washer 1. In this specification, the end face of the washer 1 represents the faces 1a and 1b in FIG. 3, the outer peripheral face of the washer 1 represents the face 1c in FIG. 3, and the inner peripheral face of the washer 1 represents the face 1d in FIG. Shall. The configuration of each part of such a washer polisher will be described in detail below with reference to the drawings.

1. Conveying Disk The configuration of the conveying disk 2 in the washer polishing apparatus configured as described above will be described with reference to the drawings. FIG. 4 is a diagram showing the configuration of the transport disk 2.

  As shown in FIG. 4, the transport disk 2 is installed so that the disks 2b and 2c into which the shaft 2a is inserted overlap each other, and the disk 2b has an outer periphery that contacts the outer peripheral surface of the washer 1 at the outermost periphery of its end surface. The polishing brush 2d is installed at equal intervals, and the inner peripheral polishing brush 2e that is in contact with the inner peripheral surface of the washer 1 is installed at equal intervals on the outermost periphery of the disk 2c. Each of the outer peripheral polishing brush 2d and the inner peripheral polishing brush 2e is installed such that its outer peripheral surface is a polishing surface and is closer to the outer peripheral side than the outer peripheral surfaces of the disks 2b and 2c. The disk 2c is provided with a notch 2f at a position where the outer peripheral brush 2d of the disk 2b is fitted. Further, a substantially fan-shaped through hole 2h extending in the circumferential direction through which four bolts 2g inserted into four screw holes provided in the disk 2b pass is provided near the center of the disk 2c.

  The notch 2f has a size in the radial direction of the disk 2c such that the end surface of the washer 1 can come into contact with the end surface of the disk 2c without the outer polishing brush 2d coming into contact with the disk 2c. The size of the direction is sufficiently wide so that the outer peripheral polishing brush 2d can move in the circumferential direction. That is, as shown in FIG. 5, the radial size Lx of the notch 2f is defined as lx between the outer periphery of the disk 2c and the outer periphery of the outer polishing brush 2d and the position closest to the center of the disk 2c. When the distance between the outer circumference of the washer 1 and the position of the washer 1 closest to the center of the disk 2c is ly, lx <Lx <ly. The circumferential size Ly of the notch 2f is such that the distance from the center of the disk 2c to each of the through holes 2h1 to 2h4 is rx, the radius of the disk 2c is Rx, and the circumference of the through holes 2h1 to 2h4. When the size of the direction is rx × θ, Ly ≧ Rx × θ (Ly = Rx × θ in FIG. 5).

  By configuring the transport disk 2 in this way, as shown in FIG. 5, the disk 2b is rotated around the shaft 2a in the circumferential direction, and the transport disk between the adjacent outer polishing brush 2d and the inner polishing brush 2e is adjacent. The distance La to the circumferential direction of 2 can be changed. Therefore, as shown in FIG. 5, the distance La between the outer peripheral polishing brush 2d and the inner peripheral polishing brush 2e is changed according to the difference rc between the inner diameter ra and the outer diameter rb of the washer 1. The distance La is such that the washer 1 can be rotated when the washer 1 is polished by the wire brushes 3a and 3b, and that the washer 1 installed on the conveying disk 2 does not come off until it moves to a position directly above the shaft 2a. Is set. In this way, when the disk 2b is positioned so that the outer peripheral surface thereof is in contact with the outer peripheral surface of the outer peripheral polishing brush 2d and the inner peripheral surface thereof is in contact with the outer peripheral surface of the inner peripheral polishing brush 2e. The disk 2b is fixed by tightening the bolt 2g. When the washer 1 is installed on the transport disk 2, the transport disk 2 rotates, so that the installed washer 1 is transported between the wire brushes 3a and 3b installed directly above the shaft 2a.

2. Next, the configuration around the grinders 4a and 4b will be described with reference to the drawings. FIG. 6 is a schematic configuration diagram seen from above showing the configuration around the grinders 4a and 4b.

  As shown in FIG. 6, the grinders 4a and 4b are installed at one ends of the support plates 5a and 5b, respectively, and the support plates 5a and 5b are rotated by the shafts 5c and 5d, respectively, whereby the distance between the grinders 4a and 4b. Is set. The shafts 5c and 5d are installed at the center portions of the support plates 5a and 5b. The other ends of the support plates 5a and 5b are respectively provided with springs 5e and 5f having one end connected to the apparatus main body (including the protective cover 7) 100, and the pulling force is applied to the grinder via the support plates 5a and 5b. By being transmitted to 4a and 4b, the force in which the wire brushes 3a and 3b pinch the washer 1 is generated. Further, by rotating the handle 6, the pressing bar 6a connected to the handle 6 and the other ends of the support plates 5a and 5b moves in the axial direction of the pressing bar 6a.

  That is, when the handle 6 is rotated in a predetermined direction, the connection point of the pressing bar 6a with the support plates 5a and 5b moves to the inside of the apparatus main body 100 and pushes the other end of the support plates 5a and 5b. When the distance between 4b increases and the handle 6 is rotated in the direction opposite to the predetermined direction, the connection point of the pressing bar 6a with the support plates 5a and 5b moves to the outside of the apparatus main body 100, and the support plates 5a and 5b. Since the springs 5e and 5f respectively pull the other ends, the distance between the grinders 4a and 4b becomes narrow. At this time, the pressing bar 6a is threaded and the hole into which the pressing bar 6a of the apparatus main body 100 is inserted is a threaded hole, so that the pressing bar 6a can be fixed, and the support plate 5a of the pressing bar 6a. , 5b can be adjusted.

  Further, as shown in FIG. 7, the grinders 4a and 4b rotate the wire brushes 3a and 3b only in the same rotation direction so that the rotation directions da and db of the wire brushes 3a and 3b are opposite to each other. In this case, the grinder 4a is installed on the upper side of the wire brush 3a, and the grinder 4b is installed on the lower side of the wire brush. In addition, when the grinders 4a and 4b can be rotated in both forward and reverse directions, the grinders 4a and 4b that are rotated in the reverse direction can be installed so that the vertical relationship with the wire brushes 3a and 3b is the same. .

  Then, friction can be exerted at the contact point between the washer 1 and the wire brushes 3a and 3b by the rotation of the grinders 4a and 4b. At this time, the rotational speeds of the grinders 4a and 4b may be the same rotational speed or different rotational speeds. Therefore, the power of the wire brushes 3a and 3b is transmitted to the washer 1, and the washer 1 rotates in the same tangential direction as the rotation direction at the contact point with the wire brushes 3a and 3b. That is, the washer 1 is perpendicular to the rotation directions da and db of the wire brushes 3a and 3b, and the tangents at the contact points with the wire brushes 3a and 3b coincide with the tangents of the rotation directions da and db of the wire brushes 3a and 3b. It rotates in the rotation direction dc. Thus, when the wire brushes 3a and 3b rotate and the washer 1 polished by the wire brushes 3a and 3b rotates, the rotation direction dc is the same as the rotation direction of the transport disk 2.

  At this time, the washer 1 is conveyed from the outside of the apparatus main body 100 into the protective cover 7, and the washer 1 polished by the wire brushes 3 a and 3 b is conveyed to the discharge guide 10 attached to the lower side of the apparatus main body 100. As shown, the transport disk 2 is rotating. Therefore, the rotation directions da, db, and dc at the contact points between the washer 1 and the wire brushes 3a and 3b are directed toward the inside of the apparatus main body 100, and dust generated by polishing with the wire brushes 3a and 3b is generated in the apparatus main body 100. Splashes toward the inside.

Further, since the washer 1 rotates, the outer peripheral surface of the washer 1 is polished by the outer peripheral polishing brush 2d of the transport disk 2, and the inner peripheral surface of the washer 1 is polished by the inner peripheral polishing brush 2e of the transport disk 2. Further, the upper side of the washer 1 is suppressed by the flat brush 3c, and the outer peripheral surface of the washer 1 is polished. A dust collector that collects dust scattered toward the inside of the apparatus main body 100 may be installed inside the apparatus main body 100.

3. Next, the configuration of the discharge guide 10 will be described with reference to the drawings. FIG. 8 is a schematic configuration diagram showing a configuration around the discharge guide 10.

  As shown in FIG. 8, the discharge guide 10 has a substantially fan shape along the outer periphery of the transport disk 2 and is installed close to the lower side of the transport disk 2. Further, the discharge guide 10 has an end surface at a position close to the direct point S of the transport disk 2 located away from the end surface of the transport disk 2, and an end surface at a position T farthest from the direct point S of the transport disk 2 is transported. It is formed in a substantially spiral shape that exists on the same plane as the end face of the disk 2. That is, the end surface of the discharge guide 10 is installed at a position away from the end surface of the transport disk 2 in the rotation direction of the transport disk 2.

  By configuring the discharge guide 10 in this way, when the washer 1 polished by the wire brushes 3a and 3b is transported to the discharge guide 10 by the transport disk 2, the point from the point S immediately below the transport disk 2 in the discharge guide 10 is reached. At the farthest position T, the end face of the washer 1 comes into contact with the end face 10 a of the discharge guide 10. At this time, as shown in FIG. 9A, the washer 1 is parallel to the transport disk 2, and the end surface 1 b of the washer 1 is in contact with the end surface 2 a of the transport disk 2 and the end surface 10 a of the discharge guide 10. . The inner peripheral surface 1d of the washer 1 is in contact with the outer peripheral surface of the inner peripheral polishing brush 2e. When the transport disk 2 further rotates and the washer 1 moves downward, the end surface 10a of the discharge guide 10 is located at a position away from the end surface 2a of the transport disk 2 as shown in FIG. The end surface 1b of the washer 1 is in contact with the inner peripheral side of the discharge guide 1 by a line, and the boundary line between the end surface 1b and the outer peripheral surface 1c of the washer 1 is in contact with the end surface 2a of the transport disk 2. Further, the boundary line between the end face 1b of the washer 1 and the inner peripheral face 1d is in contact with the outer peripheral face of the inner peripheral polishing brush 2e.

  When the transport disk 2 further rotates and the washer 1 moves further downward, the end surface 10a of the discharge guide 10 is located at a position further away from the end surface 2a of the transport disk 2 as shown in FIG. Therefore, the end surface 1b of the washer 1 is in contact with the inner peripheral side of the discharge guide 10 along a line, and the boundary line between the end surface 1b of the washer 1 and the inner peripheral surface 1d is not contacted with the transport disk 2. It will be in the state which contact | connected the outer peripheral surface of the inner periphery polishing brush 2e. At this time, the boundary line between the end face 1b and the inner peripheral face 1d of the washer 1 and the outer peripheral face of the inner peripheral brush 2e are in contact with the boundary between the end face 1b and the inner peripheral face 1d of the washer 1 in FIG. The position is farther from the end surface 2a of the conveying disk 2 than the position where the line and the outer peripheral surface of the inner peripheral polishing brush 2e are in contact. When the transport disk 2 further rotates and finally the washer 1 moves to a position immediately below the position S immediately below the transport disk 2, as shown in FIG. 9 (d), the washer 1 is in contact with the outer peripheral surface of the inner polishing brush 2e. Since the contact is not made, the washer 1 is detached from the inner polishing brush 2e of the conveying disk 2 and discharged.

  Thus, the washer polisher which each part comprises is operate | moved as follows. As shown in FIG. 10A, the washer 1p is transported by an operator so that the outer peripheral surface is in contact with the outer peripheral polishing brush 2d and the inner peripheral surface is in contact with the inner peripheral polishing brush 2e outside the protective cover 7. Installed on the disc 2. As shown in FIGS. 10B to 10D, the operator continuously installs washers 1 q to 1 v on the transport disk 2 according to the rotation of the transport disk 2. Then, the transport disk 2 rotates to transport the washer 1p from the protective cover 7 into the apparatus main body 100. At this time, when the washer 1p is transported to the position immediately above the transport disk 2, both ends of the washer 1p are in contact with the wire brushes 3a and 3b as shown in FIG. 10B, and the outer periphery of the washer 1p. The surface comes into contact with the flat brush 3c.

  As described above, when the washer 1p is conveyed between the wire brushes 3a and 3b, the rotation of the conveying disk 2 is stopped for a predetermined time, and the wire brushes 3a and 3b are rotated by the grinders 4a and 4b. The end surface, outer peripheral surface and inner peripheral surface of 1p are polished. At this time, when the diameter of the washer 1 is large or when the washer 1 is very dirty, the polishing time is lengthened. Then, when the grinders 4a and 4b are stopped rotating and the polishing of the washer 1p is finished, the transport disk 2 is rotated again. At this time, when the next washer 1q is transported between the wire brushes 3a and 3b, the rotation of the transport disk 2 is again stopped and the grinders 4a and 4b are driven to polish the washer 1q. .
