Description

DETAILED DESCRIPTION OF THE INVENTION The present invention directly uses an armature or rotor that is rotationally driven in an electric motor, and performs wiping, polishing, or grinding of wires, bars, etc. through any moving medium means. The main purpose is to reduce the size and simplification of the device, as well as to make effective use of the electric motor drive.

Therefore, in the past, this type of scouring, polishing, or grinding was performed by interposing a suitable media mechanism such as a gear, chain, or belt on the electric motor shaft to regulate the drive of the scouring device, polishing device, or grinding device. This is what I did.

Therefore, in addition to the installation space for the electric motor, installation space for the driving medium mechanism and installation space for specific equipment such as scrubbing, polishing, or grinding are required.
These wiping devices, polishing devices, or grinding devices naturally have certain limitations in terms of miniaturization and simplification.

In addition, in such conventional cases, as the transmission medium mechanism becomes more complex, the driving energy is inevitably reduced by the amount equivalent to the frictional resistance, making the running cost relatively high compared to the amount of work. That is.

Furthermore, energy loss corresponding to the play in the transmission section that is normally required in such a transmission medium mechanism was observed.

Additionally, if there is a transmission media mechanism such as a gear, chain, or belt between the driving side and the driven side of the actual device, all of these devices have been considered to be the cause of personal accidents. .

Additionally, moving elements between such devices often induce damage, which is a major cause of device failure.

The device according to the present invention uses the rotational drive of the rotary shaft of the armature or rotor itself in the electric motor, thereby omitting any transmission medium mechanism during scrubbing, polishing, and grinding, and eliminating the need for any transmission medium mechanism compared to the prior art. This is intended to eliminate any inconvenience caused. In other words, by directly using the driving shaft of the electric motor,
In addition to saving space for installing motion transmission elements, it also reduces the need for scrubbing, polishing, and installing the grinding equipment itself.
By incorporating this into the motor structure, the installation space for these devices can be effectively saved.

Next, by omitting these motion transmission elements, the abrasive resistance generated between the motion elements,
There is no energy loss due to air resistance or other motion, and it goes without saying that any possibility of failure or accident between these elements has been eliminated.

The device according to the present invention used for wiping, polishing, or grinding wire rods, bars, etc. has a structure in which the armature or rotor shaft of an electric motor is hollow;
Wipe the inside of this hollow armature or rotor shaft with a brush, etc.
In view of the provision of polishing or grinding means, the following specific embodiments and considerable design changes accompanying these embodiments are planned.

Hereinafter, a typical wiping device, polishing device, or grinding device according to the present invention will be specifically explained.The electric motor a used is planned to be of all the models commonly used at present. They are selected and used after comprehensively considering the power supply, the torque generated by the device, the purpose of the device, and the material to be processed. Therefore, it is planned to use not only a general DC motor but also an induction motor, a synchronous motor, etc.

In the illustrated example, a typical DC motor is explained for the easiest understanding, and 1 is the base, 2 is the pedestal, 3 is the oil ring, 4 is the bearing metal, and 5 is the base. 6 is the hollow shaft that constitutes the storage part of this device, 6 is the oil drainer, and 7 is the hollow shaft that constitutes the storage part of this device.
is the end cover, 8 is the armature arm, 9 is the end plate key, 10 is the end plate,
11 is the armature coil, 12 is the comb fitting, 13
14 is a compensation winding, 14 is a commutator coil, 15 is a commutator core, 16 is a laminated yoke, 17 is an armature core, 18 is a main pole core, 19 is a main pole coil, 2
0 is the rocker support, 21 is the current collector ring, 22 is the riser support, 23 is the rocker, 24 is the brush holder, 25 is the protective cover, 26 is the commutator piece, 27 is the commutator V ring , 28 is a commutator tightening bolt, 29 is a closing plate, and 30 is a commutator box.

In such an electric motor a, a shaft 5, particularly a portion corresponding to the armature or rotor shaft, is hollow, and a brush 31 is provided within the hollow shaft 5.

Therefore, the method of installing the brush 31 is selected depending on the shape, material, processing details, etc. of the workpiece b, and the embodiment shown in FIG. , the content is polishing or cutting the surface of the workpiece, which is a bar material, and the wire is inserted from the inner circumferential wall of the shaft 5 toward the axial center, leaving a gap equivalent to the gap through which the bar material passes through in the center. Brush is grown upright.

Incidentally, it is extremely difficult to install such a brush 31 into the shaft 5, and since a considerable twisting force is applied to the installed brush 31 itself, the brush 31 cannot be installed in an annular shape as shown in FIG. mounting frame 32
It was planned that the brushes 31 would be attached and prepared in advance, and the brushes would be sequentially pushed into the shaft 5 and fastened together.

Next, the embodiment shown in FIG. 3 is a relatively soft,
The brush 31 with long bristles is provided within the shaft 5 with a gap 33 left so that it can swing slightly as the workpiece b moves.

Incidentally, in attaching this brush 31, an attempt was made to improve the structure of the brush 31 in the same way as in the case described above, and as shown in FIG. 34 in a spiral shape, and the mutual frames 34 are connected to each other by spacers 3.
5 and 35 for support, and these are mounted inside the shaft 5 as an integral unit.

Various methods of attaching the brush 31 are planned, and the embodiment shown in FIG. The example shown in FIG. 7 is an example in which the brush 31 is woven together with the steel cord 37, and the example shown in FIG. 8 is a cage-like example. frame 3
8 shows an example in which a brush 31 was added to the brush 31.

It should be noted that various other shapes and materials are contemplated for the shape and material of the brush 31 and the means for attaching the brush 31 described above, and may vary depending on the shape, material, properties, and processing purpose of the workpiece b. They were also selected and used as appropriate.

Furthermore, during the actual operation of these devices, the attachment and use of various parts used for scrubbing, polishing, and grinding, such as files, rubber members, sponge members, etc., other than the brush, are separately planned. .

In addition, workpiece b by brush 31 etc. in the description
During the wiping, polishing or grinding process,
In order to make these treatments more effective, various polishing liquids, anti-rust detergents, or lubricants are supplied into the shaft 5, or when wiping, polishing, or grinding is performed on the workpiece b. With the intention of preventing compositional deterioration or high temperature of the equipment,
It is separately planned to supply cooling fluid, cooling air, lubricating oil, etc. into the shaft 5.

Furthermore, various solvents, acid or alkaline treatment liquids required for surface treatment of the workpiece b, or various liquid or solid abrasives for the purpose of enhancing the blasting effect are planned to be supplied into the shaft 5. It is what was done.

Furthermore, by connecting a vacuum pump to the shaft 5, the abrasive material or resin coating material already attached to the surface of the workpiece, or the fine powder debris generated during polishing and grinding can be effectively suctioned and removed. It was separately planned to wipe out the possibility of adsorption of foreign matter on the surface of the workpiece b derived from these devices.

The device according to the present invention has the characteristic configuration described above, and is capable of achieving specific effects on the above-mentioned properties, and is capable of wiping the outer circumferential surface of wires, bars, and other articles having a slender shape.
