Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a main body of a cleaning unit formed by attaching abrasive brushes to the tips of a plurality of rotating shafts, which is movable up and down, and suspended above a lifting platform of a pedestal. A horizontally installed material holding and transferring section that clamps the material to be polished and transfers it at a constant speed removes burrs, rust, and dirt from the material to be polished.
The present invention relates to a cleaning device that polishes away scale and the like.

Members such as gas-cut iron plates that are conventionally welded into various shapes, or splice plates that are attached to the ends of multiple steel frames and tightened with rivets or bolts in order to bring them together in one place. This is formed by drilling a large number of tightening holes in a steel plate that is cut into a certain shape. Then,
For members such as gas-cut iron plates, it is necessary to remove the welding residue that occurs on the welded surface of the material, or for splice plates, remove the burrs that occur on the outside of the inner peripheral surface of the tightening hole drilled with a drill to ensure uniform attachment and tightening. It becomes impossible to do so, and various adverse effects occur. For this reason, in recent years, in order to remove welding debris generated at the end of the welding member and burrs generated on the outside of the inner peripheral surface of the drill hole, a grindstone or a grinding brush is attached to the tip of the rotating shaft and rotated. It is designed to be polished. However, in such abrasive equipment, since the abrasive material is always rotating in a fixed direction, burrs etc. in the counter-rotation direction of the abrasive material can be accurately removed, but burrs in the same direction as the rotation direction can be accurately removed. Burrs, etc. are not removed, and in the case of parts with complex shapes, there is a concern that secondary burrs may be generated, and the shape of the material to be polished, plate thickness, degree of polishing, etc. In order to accommodate this, the entire device including the mechanism for lifting and lowering the polishing body, the movement mechanism, and the transfer mechanism for the material to be polished has to be increased in size, and there are various problems that need to be improved.

The present invention was created in view of the above circumstances, and the main body of the abrasive unit is formed by attaching abrasive brushes to the tips of a plurality of rotating shafts that revolve by a planetary gear mechanism and rotate in opposition to each other. Because of the revolution and rotation of the polishing brush, it can accurately respond to any shape of material to be polished and drilling conditions of drill holes. Accordingly, the machine is moved up and down by a screw rod as appropriate, and burrs, etc., are removed from the material to be polished, which is held and transferred by the clamping claws formed by the endless rail, and is extremely useful because it operates efficiently with a simple structure.

An embodiment of the present invention will be described based on the accompanying drawings. A planetary gear mechanism 1 has a plurality of rotating shafts, and abrasive brushes 2, 2' made of brass, nylon, stainless wire, steel wire, etc. are attached to the tips of the rotating shafts. The main body 3 of the grinding section formed by the above-mentioned method is vertically mounted on a lifting table 5 disposed below the pedestal 4 with the polishing brushes 2, 2' facing downward, and is screwed onto the lifting table 5 so as to be attached to the lower part of the pedestal 4. The screw rods 6, 6' installed upright are rotated by a drive motor 7 etc. arranged on the pedestal 4 so that the main body 3 of the grinding section can be raised and lowered together with the lifting table 5, and then the pedestal 4 is rotated.
An endless rail 10, which has clamping claws 8, 8', 9, 9' protruding from the front and back ends at regular intervals, is installed at the lower part of the rail.
10' is stretched and rotated at a constant speed,
Between these rails, clamp receiving claws 11, 11' facing opposite to the clamping claws 8, 8', 9, 9' are protruded at a constant interval, and the clamping claws 8, 8', 9, 9' are fixed at a constant distance. An endless rail 12 that rotates following the transfer load of pressure is provided, and a material holding and transferring section 13 for holding and transferring the material to be polished is installed horizontally. In the figure, 14 and 14' are interlocking shafts, 15 is a guide rod, 16 is a transfer motor, and 17 and 17' are transfer sprockets.

The present invention has the above-mentioned configuration, and to explain the process of polishing and removing burrs on a material to be polished such as a splice plate, first, the material to be polished is held and transferred by the part 13 which rotates at a constant speed. Endless rail 10,1
If the material to be polished is placed with the surface to be polished facing upward between 0', one end of the material to be polished will be caught by the clamping claws 8 and 9, and the material will be moved below the pedestal 4. but,
At this time, the other side of the material to be polished is held by the clamping pawl 11 of the endless rail 12, which can be rotated in the same direction between the endless rails 10 and 10' at low speed or in the opposite direction by a drive source (not shown) or stopped. The ends of the endless rail 12 are clamped, and the endless rail 12 follows this due to the constant pressure transfer load of the clamping claws 8 and 9.
The material to be polished is clamped and transferred by the clamping claws 8, 9 and the clamping claw 11 in the same direction as 0 and 10'. When the material to be polished is transferred into the pedestal 4 in this manner, the main body 3 of the grinding section, which had been waiting above, rotates the screw rods 6, 6' by the operation of the drive motor 7 disposed on the pedestal 4. A lifting platform 5 that is screwed onto lowers a certain height, and a plurality of cleaning brushes 2 that rotate while revolving around the bottom surface of the cleaning section main body 3,
2' is used to remove burrs and the like from the material to be polished. At this time, the endless rails 10, 10', 12 may be moved slowly or temporarily stopped depending on the condition of burrs generated on the material to be ground. The degree of polishing of the material to be polished can be changed by appropriately adjusting the degree of descent of the material.
Further, the lowering of the main body 3 of the cleaning section may be carried out by moving the endless rails 10, 10', 12 fixed at that position, as long as the shape and thickness of the material to be polished are constant. When the burrs on the material to be polished are removed by polishing in this manner, the endless rails 10 and 10' transfer the material to the other end of the material holding and transferring section 13, and the endless rail 12 from which the holding pawl 11 is protruded connects to the sprocket 17. When the receiving claw 11 is rotated downward by `, the receiving claw 11 comes off from the other end of the material to be polished, releases the clamping pressure on the material to be polished, and transfers the material to be polished to the other end of the transfer section 13. This completes the lever polishing process.

In the present invention, a main body 3 of a grinding part by means of a planetary gear mechanism 1 in which a plurality of abrasive brushes 2, 2' rotate while revolving around the same axis is vertically disposed on a lifting table 5 disposed within a pedestal 4, and is provided below the pedestal 4. has endless rails 10, 10', 1
The simple configuration in which the transfer section 13 of 2 is installed horizontally allows the material to be polished to be reliably held and transferred while the polishing brushes 2 and 2' accurately remove burrs, which is extremely useful for improving work efficiency. It is something.
