5 and 6 show the overall appearance of the double-sided edge processing portable device according to the present invention. 7 shows a view of the present invention from the rear side, FIG. 8 from the left side, FIG. 9 from the front side, and FIG. 10 from the bottom side (bottom). 11 is a photograph showing a situation in which the double-sided edge processing portable apparatus according to the present invention is actually put into the machining operation for the manhole.

The double-sided edge processing portable apparatus according to the present invention is an apparatus for automatically performing the surface treatment for the edge of the workpiece while driving automatically using the air motor, the driving wheel 10, the double-sided edge processing tool 20, It includes a permanent magnet 30, the driving guide 40 and the operation lever 60. Hereinafter, each component will be described in detail.

Wheel

The driving wheel 10 is mounted on the lower surface of the body portion 70 of the double-sided edge processing portable apparatus according to the present invention, and rotates according to the driving of the traveling motor 80. Then, according to the rotation of the driving wheel 10, the double-sided edge processing portable apparatus according to the present invention is traveling on the working surface.

At this time, in order to enable the double-sided edge processing portable apparatus according to the present invention to travel in a close state without slipping on the work surface, the driving wheel 10 is preferably made of a rubber material.

In the case of the present invention, the driving wheel 10 is characterized in that it is mounted in a state of being twisted by a predetermined angle with respect to the running direction (front) of the body portion 70 (Fig. 10), the reason for this will be described based on Fig. Is as follows.

When machining the manhole of FIG. 11, the double-sided edge machining tool 20 automatically performs the machining operation while moving on the edge of the manhole according to the driving of the driving wheel 10 while being over the edge of the manhole. At this time, since the traveling wheel 10 is mounted in a state in which the driving wheel 10 is turned by a predetermined angle with respect to the traveling direction A (work progress direction) of the body part 70, the traveling wheel 10 continuously operates in the B direction (traveling). To the mounting direction of the wheel 10). As a result, the driving wheel 10 serves to drive the body portion 70 in the A direction while pulling the double-sided edge processing tool 20 in the C direction across the edge of the manhole. Through this process, the double-sided edge machining tool 20 can maintain a state of being in constant contact (direction C) without falling off the corners of the manhole during movement (direction A), thereby resulting in an effect of improving processing quality.

On the other hand, if the running wheel 10 has a too small angle with respect to the running direction of the body portion 70, the force to pull the double-sided edge machining tool 20 in the C direction as described above becomes very weak, thereby improving processing quality. It is difficult to expect, and on the contrary, if the angle is too large, it may interfere with the running of the body portion 70, so that the distorted angle of the driving wheel 10 is preferably determined by considering both sides appropriately. Do.

In the embodiment according to the present invention, as a result of experiments for various situations, when the twisted angle of the driving wheel 10 is about 7 degrees while securing the force to pull the double-sided edge machining tool 20 in the C direction to a certain level or more. It was confirmed that it does not interfere with the running of the body portion 70.

In the case of the present invention, the driving wheel 10 is composed of two front wheels 11 and three rear wheels 12, in particular, the rear wheel 12 is characterized by three (Fig. 10), the reason is also shown in Figure 11 The explanation is as follows. And the reason is explained on the premise of the situation that only the body portion 70 is running in a state in which the double-sided edge machining tool 20 does not operate, that is, no machining operation in FIG.

In FIG. 11, the double-sided edge machining tool 20 moves on the edge of the manhole according to the driving of the driving wheel 10 in a state spanning the edge of the manhole. At this time, as described above, the force acts in the C direction with respect to the double-sided edge machining tool 20, and as a result, the body portion 70 is intended to rotate about the double-sided edge machining tool 20 in the D direction. Will have The force acting in the C direction is to provide a kind of rotation moment with respect to the body portion (70). When the body portion 70 rotates in the D direction, the rear wheel 12 of the driving wheel 10 may fall out of the manhole. If the rear wheel 12 consists of only two, one rear wheel 12 is It is very difficult for the body part 70 to travel normally with only one rear wheel 12 in a state where it has fallen into the manhole. However, if there are three rear wheels 12 as in the case of the present invention, even if one rear wheel 12 is pulled into the manhole, the remaining two rear wheels 12 may allow the body 70 to run normally. There is no problem.

Meanwhile, in the case of the present invention, the driving wheel 10 is connected to the front wheel 11 and the rear wheel 12 by a power transmission chain 13 (FIG. 10).

In this case, when the front wheel 11 gets power according to the driving of the traveling motor 80, the power is transmitted to the rear wheel 12 by the power transmission chain 13. As a result, in the case of the present invention, four-wheel drive is possible. Thus, the present invention adopts the four-wheel drive method to induce stable driving of the double-sided edge processing portable device according to the present invention by transmitting a constant force to all the driving wheels 10. This is to improve the processing quality through this.

Duplex Edge Machining Tool

The double-sided edge machining tool 20 is mounted on the lower surface of the body portion 70 of the double-sided edge machining portable apparatus according to the present invention, and rotates according to the driving of the tool motor 90. The double-sided edge cutting tool 20 automatically faces the workpiece while moving on the edge of the workpiece in accordance with the driving wheel 10 while the rotary cutters 21 and 21 'are over the edge of the workpiece. Machining operation such as will be performed (Fig. 11).

In the present invention, the double-sided edge machining tool 20 is characterized in that two rotary cutters 21 and 21 'face each other symmetrically (Fig. 5). In other words, the double-sided edge cutting tool 20 according to the present invention is capable of simultaneously chamfering the upper and lower edges of the workpiece simultaneously by using two rotary cutters 21 and 21 'mounted to face each other symmetrically. (F in FIG. 11).

At this time, the rotary cutter 21 is connected to the inner rotary shaft (not shown) mounted in the body of the double-sided edge machining tool 20 to rotate with the rotation of the inner rotary shaft, the rotary cutter 21 'end of the insertion rotary shaft 22 Is connected to the rotation with the rotation of the insertion shaft 22.

The reason for arranging the rotary cutters 21 and 21 'in the present invention is that the mutually opposed distances of the two rotary cutters 21 and 21' are adjusted through a process of adjusting the insertion length of the insertion rotary shaft 22 (Fig. 5). To control L).

When the operator pushes or pulls the insertion shaft 22, the insertion shaft 22 has a different insertion length for the double-sided edge machining tool 20 body. That is, when the operator pushes the insertion rotary shaft 22 into the double-sided edge machining tool 20 body, the insertion length of the insertion rotary shaft 22 increases, and on the contrary, when the insertion rotary shaft 22 is pulled out of the double-sided edge machining tool 20 body, the insertion is inserted. The insertion length of the rotating shaft 22 is to be reduced. In this case, the position of the insertion shaft 22 is fixed with three screws.

In this case, when the insertion length of the insertion rotary shaft 22 is increased, the mutually opposed distances L of the two rotary cutters 21 and 21 'are reduced, and when the insertion length of the insertion rotary shaft 22 is reduced, the two rotary cutters ( The mutually opposed distances L of 21, 21 ') increase.

According to the present invention, since the mutually opposed distances L of the rotary cutters 21 and 21 'can be freely adjusted, the operator can easily cope with the change in the thickness of the workpiece. That is, if the thickness of the workpiece is thin, the mutually opposed distance L of the rotary cutters 21 and 21 'may be reduced to match the thickness of the workpiece, and if the thickness of the workpiece is thick, the rotary cutters 21 and 21' may be adapted to the thickness of the workpiece. It is necessary to increase the mutually opposed distance L.

On the other hand, in the present invention, in order to allow the operator to finely adjust the mutually opposed distance (L) of the rotary cutter (21, 21 '), it is good to mark the scale on the surface of the insertion rotary shaft (22).

In addition, the insertion shaft 22 is preferably such that its cross section takes the form of a polygon.

Insertion rotation shaft 22 is rotated by receiving the rotational force of the internal rotation shaft in the state inserted into the double-sided edge machining tool 20 body, if the cross section of the insertion rotation shaft 22 takes the form of a polygon, if no slip occurs This is because it is advantageous because power transmission can be made smoothly.

Permanent magnet

Permanent magnet 30 is mounted on the lower surface of the body portion 70 of the double-sided edge processing portable device according to the present invention.

By virtue of the magnetic force generated by the permanent magnet 30, the body portion 70 can be stably traveled without falling from the working surface (FIG. 11).

At this time, the permanent magnet 30 is preferably mounted so as to maintain a distance of about 1.5 millimeters with respect to the working surface (G in Fig. 9). This is to avoid the case in which the permanent magnet 30 interferes with the running of the double-sided edge processing portable device according to the present invention due to contact with the work surface or cause interference with the work surface.

Driving guide

The travel guide 40 is mounted on the lower surface of the body portion 70 of the double-sided edge processing portable apparatus according to the present invention, and maintains the state over the edge of the workpiece, while the body portion during the machining operation of the double-sided edge processing tool 20. 70) prevents the rotation. This will be described based on FIG. 11. And the description thereof is made on the premise that the body portion 70 is running in a state in which the double-sided edge machining tool 20 is operated in FIG.

When machining the manhole of FIG. 11, the double-sided edge machining tool 20 automatically performs the machining operation while moving on the edge of the manhole according to the driving of the driving wheel 10 while being over the edge of the manhole. At this time, the two rotary cutters 21 and 21 'mounted to face each other symmetrically chamfer the upper and lower edges of the workpiece simultaneously. In this case, the rotary directions of the rotary cutters 21 and 21' are counterclockwise. to be. In addition, due to the counterclockwise rotational force of the rotary cutters 21 and 21 ′, the body 70 has a property of rotating in the E direction with respect to the double-sided edge machining tool 20. The rotational force of the rotary cutters 21 and 21 'provides a kind of rotation moment with respect to the body portion 70.

Of course, as described above, the body portion 70 has a property to rotate in the D direction with respect to the double-sided edge machining tool 20 by the force acting in the C direction with respect to the double-sided edge machining tool 20. In this case, however, the counterclockwise rotational force of the rotary cutters 21 and 21 'is so great in this case (the state where the two-sided edge machining tool 20 is operating), the property to rotate in the D direction is canceled and consequently the body The part 70 is to have the property to rotate in the E direction with respect to the double-sided edge machining tool 20.

If the state is left as it is, the body portion 70 will return to the counterclockwise direction on the working surface and finally fall into the manhole. However, in the case of the present invention, the driving guide 40 mounted at the rear of the double-sided edge machining tool 20 is held in correspondence to the counterclockwise rotation of the body portion 70 while maintaining the state spanning the corners of the manhole. The problem that the body part 70 falls into the manhole does not occur.

On the other hand, in order for the traveling guide 40 to perform the above-described role more effectively, the traveling guide 40 has the same side position as the double-sided edge machining tool 20 at the rear of the double-sided edge machining tool 20. It is desirable to be mounted on (Fig. 5, Fig. 10).

The operation lever 60 is mounted on the body portion 70 of the double-sided edge processing portable apparatus according to the present invention, and a button for allowing an operator to control driving of the driving wheel 10 and the double-sided edge processing tool 20 ( Or handle).

The operator can control the driving speed and the driving direction of the driving motor 80 and the tool motor 90 by using the operation lever 60. That is, the operator can control the driving speed of the driving motor 80 and the tool motor 90 by adjusting the air amount of the air motor using the operation lever 60, thereby rotating the speed of the driving wheel 10 Traveling speed of the double-sided edge processing portable apparatus according to the present invention) and the rotary speeds of the rotary cutters 21 and 21 'of the double-sided edge processing tool 20 can be controlled. In addition, the operator adjusts the driving direction of the driving motor 80 by using the operation lever 60 to rotate the driving wheel 10 (forward and backward of the double-sided edge processing portable apparatus according to the present invention) and the double-sided edge processing tool. The rotation direction of the rotary cutters 21 and 21 'of 20 can be freely controlled.

On the other hand, in order to allow the operator to easily handle the operation lever 60 on the job site, the operation lever 60 is preferably manufactured to be in the form of a joystick.
