Description

Board Sides Edge Milling Portable Equipment for Thick Plate

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for surface treatment, such as chamfering, on a cutting surface or an edge of a manhole in processing a workpiece used in various machine tools or vessels.

In processing workpieces used in various machine tools or ships, it is necessary to perform surface treatment (chamfering) such as chamfering on the cutting surface or the corner of the manhole.

In general, when rounding or chamfering the corners of a workpiece, the grinder is chamfered by eye guessing, so the angle of chamfering is not constant, precise and uniform chamfering is not possible, and it takes a lot of time and efficient work. Closure often occurs.

In order to solve this problem, various technologies have been continuously developed in the related art, and the 'corner processing apparatus' (hereinafter referred to as 'prior art 1') of patent application No. 10-2006-0122822, patent application No. 10-1995- 0023455, 'Method of forming corners of each member and its apparatus' (hereinafter referred to as 'prior art 2'), 'portable chamfering' of patent application 10-2006-0122052 (hereinafter referred to as 'prior art 3') For example, 'multipurpose chamfering machine' (hereinafter referred to as 'prior art 4') of Patent Application No. 10-2007-0106058 corresponds to this. However, it cannot be denied that such prior art also has its own defects or technical limitations.

The prior art 1 (Fig. 17) is a device for processing the edge while transporting on the workpiece, while processing the edge while rotating the cutter in a symmetrical mechanism structure. Prior art 1 is a flat-bar dedicated processing equipment, which has the advantage of being detachable and capable of simultaneously machining both sides, but using holes such as overhead work, vertical work, and manholes. It is not suitable for double-sided processing of (Hole). In addition, there is a need to configure a separate drive and control box using an AC servo motor. In addition, there is a problem that the portable function is reduced because the weight is about 20Kg.

Prior art 2 (Fig. 18) can be formed into a curved shape by pressing the edge of the member with a forming roller as a processing equipment of the square member, the corner of the steel. That is, the prior art 2 is a device for installing the equipment in the vicinity of the moving path of the member in order to mold the corner of each member having an edge and press the forming roller to process the required shape. Therefore, the size of the equipment is large, the mobility is inferior and difficult to process various types of members. In addition, there is a disadvantage that can be used only in the processing step and can not be used in the assembly step.

The prior art 3 (Fig. 19) is a portable chamfering device that can be processed precisely and easily the edge while moving along the workpiece in the operator gripped state. The prior art 3 has the advantage that it can be used precisely and conveniently in the state of the operator by using a tool that fits the machining shape, but it is impossible to process both sides at the same time and the quality of the machining surface may vary depending on the skill of the operator. There are disadvantages. In addition, there is a risk of causing musculoskeletal disorders of the worker when working for a long time is a problem.

Prior art 4 (Fig. 20) is a multi-purpose chamfering device that can be used to machine the corner by mounting the chamfering tool for right angle, acute angle, corner. The prior art 4 has the advantage that it is possible to process the straight and curved section and chamfering to the corner of the member, but both sides are difficult to simultaneously process and is driven by manual operation of the operator, there is a disadvantage that the quality difference occurs depending on the operator. In addition, there is a risk of causing musculoskeletal disorders of the worker when working for a long time is a problem.

In order to solve such a problem of the prior art, the applicant has developed a "double-sided edge processing portable device" (hereinafter referred to as "prior art 5") as shown in Figure 16 and filed a patent application on November 23, 2009 (Patent Application No. 10-2009-0113106), and has received a patent registration on April 9, 2010 (Patent Registration No. 10-0953503).

The prior art 5 is a device for processing the surface of the workpiece, such as chamfering, automatic driving and processing using the air motor, simultaneous machining on both sides, vertical, overhead (Vertical) It is possible to drive to various working surfaces such as), curved surface, and manhole, as well as to machine various parts such as manhole, flat-bar, T-bar, and angle. to be.

However, the applicant has found the following problems in the process of performing the prior art 5 for the surface treatment operation of the workpiece.

First, a subtle quality difference occurs depending on the pressure of the compressed air supplied. That is, in the related art 5, the compressed air supplied to the traveling motor (80 of FIG. 16) and the tool motor (90 of FIG. 16) is used when there is no facility to keep the pressure of the compressed air constant or when the air supply line is used in a long site. Pressure is uneven and processing quality deteriorates.

Second, it is difficult to apply to thick workpieces. In some cases, such as hatch coaming of ships, the thickness of the steel sheet is often 80 millimeters or more. If too long, the insertion rotation axis becomes longer, the vibration is generated a lot of quality processing quality can not be obtained, in particular, the outer rotary cutter (21 'of Fig. 16) of the double-sided edge machining tool is heavily loaded and damaged Problems such as being caused. And this phenomenon began to occur when the thickness of the steel sheet is more than 45 millimeters experimentally.

The present invention is to solve the problems of the prior art 5 as described above, the automatic running on a variety of work surfaces, such as vertical (Vertical), overhead, curved (surface), manhole, manhole, flat-bar It is possible not only to simultaneously process both sides of various members such as T-bar, angle, etc., but also to maintain the homeostasis of processing quality by uniformizing the pressure of compressed air supplied, especially thick workpiece It is an object of the present invention to provide a thick plate applied double-sided edge processing apparatus that can be stably applied without defects such as vibration and damage.

Hereinafter, the present invention will be described in detail for each component, with reference to FIGS. 1 and 2.

<Upper module>

Upper wheel

The upper driving wheel 12 is mounted on the lower surface of the upper body 11 and rotates according to the driving of the driving motor 12d. As the upper driving wheel 12 rotates, the upper module 10 travels on the upper surface of the workpiece (FIGS. 1 to 4).

In this case, the upper driving wheel 12 is preferably made of rubber in order to allow the upper module 10 to travel in a state of being in close contact with the upper surface of the workpiece without slipping.

In the case of the present invention, the upper driving wheel 12 is mounted in a state in which the upper body 11 is turned by a predetermined angle with respect to the driving direction (front) of the upper body 11 (FIG. 22). Is as follows.

In the machining operation of the manhole of Fig. 21, the upper rotary cutter 13a, the lower rotary cutter 23a, and the tool rotating shaft 30 (each of which will be described in detail later). For convenience of description, hereinafter, the upper rotary cutter 13a, the lower rotary cutter 23a, and the tool rotating shaft 30 are collectively referred to as a 'tool module', and the upper driving wheel 12 may be disposed over the edge of the manhole. In accordance with the movement of the manhole is moved automatically on the corner of the machining process.

At this time, since the upper driving wheel 12 is mounted in a state in which the upper driving wheel 12 is twisted by a predetermined angle with respect to the driving direction (A, working progress direction) of the upper body 11, the upper driving wheel 12 continuously operates in the B direction during work. It rotates toward (the mounting direction of the upper running wheel 12). As a result, the upper driving wheel 12 serves to drive the upper body 11 in the A direction while pulling the tool module in the C direction across the edge of the manhole. Through this process, the tool module can remain in close contact (direction C) without falling off the edge of the manhole during movement (direction A), thereby resulting in an effect of improving processing quality.

On the other hand, if the angle in which the upper driving wheel 12 is twisted with respect to the driving direction of the upper body 11 is too small, the force to pull the tool module in the C direction as described above is very weak, so that it is expected to improve the processing quality. If the angle is too large, on the contrary, too much may interfere with the running of the upper body 11, it is preferable to determine the twisted angle of the upper driving wheel 12 in consideration of these two aspects as appropriate.

In the embodiment according to the present invention, as a result of experiments for various situations, when the twisted angle (d in FIG. 22) of the upper driving wheel 12 is about 1 degree to 10 degrees, the force to pull the tool module in the C direction While ensuring a certain level or more was confirmed that does not interfere with the running of the upper body (11).

In the case of the present invention, the upper driving wheel 12 is composed of two front wheels 12a and three rear wheels 12b, and in particular, the rear wheel 12b is characterized by three (Fig. 22), and the reason is also shown in Fig. 21. Based on the following description. And the reason is described on the premise that only the upper body 11 is driven in a state in which the tool module does not operate, that is, no machining operation in FIG.

In FIG. 21, the tool module moves on the corner of the manhole according to the driving of the upper driving wheel 12 in a state spanning the corner of the manhole. At this time, as described above, the force acts in the C direction with respect to the tool module, and as a result, the upper body 11 has a property to rotate in the D direction about the tool module. The force acting in the C direction is to provide a kind of rotation moment with respect to the upper body (11). If the upper body 11 rotates in the D direction, the rear wheel 12b of the upper driving wheel 12 may fall into the manhole. If the rear wheel 12b is composed of only two rear wheels 12b, It will be very difficult for the upper body 11 to drive normally with only one rear wheel 12b in the state where the manhole has fallen out. However, if there are three rear wheels 12b as in the case of the present invention, even if one rear wheel 12b falls into the manhole, the upper body 11 may operate normally with the remaining two rear wheels 12b. There is no problem.

On the other hand, in the case of the present invention, the upper wheel 12, the front wheel 12a and the rear wheel 12b is interconnected by a power transmission chain 12c (Fig. 22).

In this case, when the front wheel 12a obtains power according to the driving of the travel motor 12d, the power is transmitted to the rear wheel 12b on the power transmission chain 12c. As a result, in the case of the present invention, four-wheel drive is possible. Thus, the reason for the four-wheel drive method of the present invention is that stable driving of the thick plate applied double-sided edge processing apparatus according to the present invention by transmitting a constant force to all the upper driving wheels 12. This is to induce and improve the processing quality.

Upper rotary cutter, upper tool unit

The upper tool unit 13 is mounted to the upper body 11 and generates a rotational force in accordance with the driving of the tool motor 13b (FIGS. 1 to 4).

The upper rotary cutter 13a is mounted on the upper tool unit 13. The upper rotary cutter 13a rotates together along a rotational axis installed inside the upper tool unit 13. In operation, the upper rotary cutter 13a is in contact with the upper edge of the workpiece. In accordance with the driving, the upper edge of the workpiece is moved while automatically performing machining operations such as surface treatment (FIG. 15).

Upper permanent magnet

The upper permanent magnet 14 is mounted on the lower surface of the upper body 11 (Figs. 4 and 22).

By the magnetic force generated by the upper permanent magnet 14, the upper body 11 can run stably without departing from the working surface (Fig. 15).

At this time, the upper permanent magnet 14 is preferably mounted to maintain a distance of about 1 millimeter to 10 millimeters with respect to the working surface (Fig. 23 c). This is to avoid the case that the upper permanent magnet 14 is in contact with the work surface or interfere with the work surface to interfere with the running of the thick plate applied double-sided edge processing apparatus according to the present invention.

Driving guide

The driving guide 16 is mounted on the lower surface of the upper body 11 (FIGS. 1 and 3), and prevents the upper body 11 from rotating during the machining of the tool module while maintaining the state across the edge of the workpiece. Play a role. This will be described based on FIG. 21. And the description thereof is made on the premise that the upper body 11 is running in a state in which the tool module is operating in Figure 21, that is, a machining operation.

When machining the manhole of FIG. 21, the tool module automatically performs the machining operation while moving on the edge of the manhole according to the driving of the upper driving wheel 12 while being over the edge of the manhole. At this time, the tool module chamfers the upper and lower edges of the workpiece at the same time. In this case, the rotation directions of the upper rotary cutter 13a and the lower rotary cutter 23a are counterclockwise. In addition, due to the counterclockwise rotational force of the upper rotary cutter 13a and the lower rotary cutter 23a, the upper body 11 has a property of rotating in the E direction with respect to the tool module. The rotational force of the upper rotary cutter 13a and the lower rotary cutter 23a provides a kind of rotation moment with respect to the upper body 11.

Of course, as described above, the upper body 11 has a property to rotate in the D direction with respect to the tool module by the force acting in the C direction with respect to the tool module, in this case (the tool module operates) ), The counterclockwise rotational force of the upper rotary cutter 13a and the lower rotary cutter 23a is so great that the property to be rotated in the D direction is canceled and as a result, the upper body 11 is centered on the tool module. To have the property to rotate in the E direction.

If this state is left as it is, the upper body 11 will return counterclockwise from the working surface and finally fall into the manhole. However, in the case of the present invention, the driving guide 16 mounted on the rear of the upper tool unit 13 is held in correspondence with the counterclockwise rotation of the upper body 11 while maintaining the state spanning the edge of the manhole. The problem that the body 11 falls into the manhole does not occur.

On the other hand, in order for the driving guide 16 to perform the above-described role more effectively, the driving guide 16 is mounted at the same side position as the upper tool unit 13 at the rear of the upper tool unit 13. It is preferable to make it (FIG. 3).

Upper guide unit, travel motor, tool motor, air tank

The upper guide unit 15 is mounted to the upper body 11 (FIG. 1), and the upper guide unit 15 is equipped with an upper end of the guide shaft 40 (which will be described later) (FIG. 1).

The driving motor 12d is mounted to the upper body 11 (FIG. 1), and serves to provide rotational force to the upper driving wheel 12.

The tool motor 13b is mounted to the upper body 11 (FIG. 1), and serves to provide rotational force to the upper tool unit 13.

The air tank 17 is mounted on the upper body 11 (FIG. 1), and serves to maintain a constant air pressure supplied to the travel motor 12d and the tool motor 13b. By maintaining the air pressure supplied to the travel motor 12d and the tool motor 13b at a constant level, it is possible to ensure high quality processing quality.

Forward and reverse levers, tool motor valve

The forward and backward levers 18 are mounted on the upper body 11 (FIG. 2), and the operator can control the forward and backward driving and driving speeds of the upper driving wheels 12 using the forward and backward levers 18. Can be.

That is, the operator can control the forward and backward driving and the driving speed of the travel motor 12d by adjusting the air pressure of the travel motor 12d by using the forward and backward lever 18, whereby the upper travel wheel 12 It is possible to control the rotational direction and speed of (traveling direction and speed of the thick plate applied double-sided edge processing apparatus according to the present invention).

On the other hand, the forward and backward lever 18 is preferably manufactured to be in the form of a joystick in order for the operator to easily handle on the job site.

The tool motor valve 13c controls the drive of the tool motor 13b quickly by turning on / off the supply of air pressure to the tool motor 13b (FIG. 2).

<Lower Module>

Lower wheel

The lower driving wheel 22 is mounted to the lower body 21 (FIGS. 1 and 5).

When the upper driving wheel 12 rotates as the driving motor 12d is driven, and the upper module 10 travels the upper surface of the workpiece as the upper driving wheel 12 rotates, the tool rotating shaft 30 and The lower module 20, which is mechanically connected to the upper module 10 by the guide shaft 40, also moves together with the upper module 10 (FIGS. 1 and 15).

In this case, the lower driving wheel 22 rotates in accordance with the movement of the lower module 20 so that the lower module 20 can easily travel the lower surface of the workpiece. In this case, the lower driving wheel 22 is preferably made of rubber in order to allow the lower module 20 to travel in a state of being in close contact with the lower surface of the workpiece without slipping.

The lower driving wheel 22 is mounted at a predetermined angle with respect to the driving direction (front) of the lower body 21, which is characterized in that it is mounted (a of FIG. 11), for the reason as described above. 12) is the same as being mounted in a state of being twisted by a predetermined angle with respect to the running direction of the upper body (11).

At this time, if the lower running wheel 22 has a wrong angle with respect to the driving direction of the lower body 21, the pulling force of the tool module becomes very weak, and it is difficult to expect an improvement in machining quality. Since too large may interfere with the running of the lower body 21, it is preferable to determine the twisted angle of the lower driving wheel 22 in consideration of these two aspects as appropriate.

In the embodiment according to the present invention, as a result of experiments for various situations, when the twisted angle of the lower driving wheel 22 is about 1 to 10 degrees, while securing the force to pull the tool module to a certain level or more lower body ( 21) it was confirmed that it does not interfere with the running. In the embodiment of FIG. 11, the angle of the front wheels 22a of the lower driving wheels 22 is about 1 to 10 degrees.

Lower rotary cutter, lower tool unit

The lower tool unit 23 is mounted to the lower body 21 (FIG. 5), and receives the rotational force generated in the upper tool unit 13 through the tool rotation shaft 30 (FIG. 1). Therefore, the lower tool unit 23 is driven to rotate in the same state as the rotational drive of the upper tool unit 13. That is, the lower tool unit 23 rotates together when the upper tool unit 13 rotates (more precisely, when the rotary shaft installed inside the upper tool unit 13 rotates) and the upper tool unit 13 stops. If you stop it together. The lower tool unit 23 has the same rotational force and rotational speed as the upper tool unit 13.

The lower rotary cutter 23a is mounted on the lower tool unit 23 (FIGS. 7, 1). The lower rotary cutter 23a rotates together with the rotation of the tool rotating shaft 30 and the lower tool unit 23. During operation, the lower rotary cutter 23a is in contact with the lower edge of the workpiece, and the lower driving wheel ( In accordance with the driving of 22) while moving the lower edge of the workpiece to automatically perform the machining operations such as surface treatment (Fig. 15).

In the present invention, the upper rotary cutter 13a and the lower rotary cutter 23a are characterized in that they face each other symmetrically (FIG. 1). That is, the present invention allows the two upper rotary cutters 13a and the lower rotary cutter 23a, which are mounted to face each other symmetrically, to abut the upper and lower edges of the workpiece simultaneously so that they can be chamfered efficiently ( 15).

Lower permanent magnet

The lower permanent magnet 24 is mounted to the lower body 21 (FIG. 5).

By the magnetic force generated by the lower permanent magnet 24, the lower body 21 can run stably without falling from the working surface (Fig. 15).

Of course, according to the present invention, since the lower module 20 is mechanically connected to the upper module 10 by the tool rotation shaft 30 and the guide shaft 40, even if the lower permanent magnet 24 is not provided separately, the lower module 20 ) (Lower body 21) does not fall off the work surface.

However, by mounting the lower permanent magnet 24 to the lower body 21, the traction and running stability to the working surface of the lower module 20 is further increased (for example, a state in which vibration or shaking is reduced) (Of course, the traction and running stability of the working surface of the upper module 10 are further increased.) Accordingly, the lower rotary cutter 23a is also more stably in contact with the lower edge of the workpiece. It is possible to carry out machining operations such as surface treatment while moving the edges. (Of course, the upper rotary cutter 13a also moves the upper edge of the workpiece while stably contacting the upper edge of the workpiece. Can be processed).

At this time, the lower permanent magnet 24 is preferably mounted to maintain a distance of about 1 millimeter to 10 millimeters with respect to the working surface (Fig. 11b). This is to avoid the case that the lower permanent magnet 24 interferes with the traveling of the thick plate applied double-sided edge processing apparatus according to the present invention due to the contact or interference with the working surface.

That is, the present invention includes the upper module 10 (including the upper permanent magnet 14) and the lower module 20 (including the lower permanent magnet 24) paired up and down as shown in FIG. 15. The upper rotary cutter 13a and the lower rotary cutter 23a, which are respectively provided and the upper module 10 and the lower module 20 are seated on the upper and lower surfaces of the workpiece, respectively, and are in contact with the upper and lower edges of the workpiece. ) Can be effectively chamfered.

In this case, the upper rotary cutter 13a is supported by the upper module 10 to stably move on the upper edge of the workpiece without being shaken to perform machining operations such as surface treatment, and the lower rotary cutter 23a is a lower module. Receiving the support of (20) to perform a stable operation such as surface treatment while moving stably on the lower edge of the workpiece.

This structure makes it possible to express more advantageous and significant effects, especially when the invention is applied to thick workpieces (FIG. 14).

That is, as described above, in the case of the prior art 5, if the insertion rotation shaft (22 in FIG. 16) of the double-sided edge machining tool (20 in FIG. 16) is extended too long to be applied to a thick workpiece, the insertion rotation shaft becomes longer. Therefore, a lot of vibration is generated, and thus a high quality machining quality cannot be obtained, and in particular, the external rotary cutter (21 ′ in FIG. 16) of the double-sided edge machining tool suffers from a large load and is damaged, but in the case of the present invention, Although the mutually opposed distance (L in FIG. 1) between the upper rotary cutter 13a and the lower rotary cutter 23a increases considerably for application to a thick workpiece (a detailed description thereof will be described later), the upper rotary cutter 13a ) And the lower rotary cutter 23a are balanced evenly by the support of the upper module 10 and the lower module 20, respectively, so that a lot of vibrations or loads are no longer a problem. It is not raw.

Lower guide unit

The lower guide unit 25 is mounted to the lower body 21 (FIG. 5).

The lower guide unit 25 is equipped with a lower end of the guide shaft 40 (which will be described later) (FIG. 1). In this case, the lower guide unit 25 has a fixing pin 25a for more firm mounting of the guide shaft 40 (FIG. 5).

<Tool axis of rotation>

The tool axis of rotation 30 is an axial structure, the upper and lower ends of which are mounted to the upper tool unit 13 and the lower tool unit 23, respectively, to mechanically connect the upper tool unit 13 and the lower tool unit 23. (FIG. 1, FIG. 15). In this state, the tool rotation shaft 30 transmits the rotational force generated in the upper tool unit 13 to the lower tool unit 23.

According to the embodiment of the present invention in Figure 1, the upper end of the tool axis of rotation 30 is mounted in a manner that fits into the groove formed in the upper tool unit 13, the lower end through the hole formed in the lower tool unit 23 It is mounted in such a way that it is inserted.

At this time, the tool axis of rotation 30 has a polygonal cross section, as shown in FIG. It is desirable to make it almost coincide with, so that unnecessary slip does not occur.

Since the tool rotation shaft 30 is rotated by receiving the rotational force of the upper tool unit 13 while being mounted on the upper tool unit 13 and the lower tool unit 23, the rotational force is transmitted to the lower tool unit 23. This is because, in the case where the cross section of the tool rotation shaft 30 has the form described above, it is advantageous because the loss of rotational force transmission does not occur even without unnecessary slip.

Meanwhile, in the present invention, the mutually opposed distance between the upper rotary cutter 13a and the lower rotary cutter 23a through a process of adjusting the mounting position of the lower tool unit 23 with respect to the tool rotation shaft 30 (L in FIG. 1). When the tool axis of rotation 30 is mounted on the lower tool unit 23, the lower tool unit 23 is moved up or down (which pushes or pulls the entire lower module 20). This can be achieved through the process, whereby the mounting position with respect to the guide shaft 40 of the lower guide unit 25 is also changed.) The mutually opposed distance L between the upper rotary cutter 13a and the lower rotary cutter 23a ) Will change.

That is, when the lower tool unit 23 is moved upward along the tool rotation axis 30, the mutually opposed distance L between the upper rotary cutter 13a and the lower rotary cutter 23a is reduced, and conversely, the lower tool unit 23 is moved. Moving downward along the tool axis of rotation 30 increases the mutually opposed distance L between the upper rotary cutter 13a and the lower rotary cutter 23a.

FIG. 14 shows an embodiment in which the mutually opposed distance L between the upper rotary cutter 13a and the lower rotary cutter 23a is variously adjusted according to a change in the thickness of the workpiece. According to the present invention, since the mutually opposed distance L between the upper rotary cutter 13a and the lower rotary cutter 23a 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 counter distance L may be reduced to match it. If the thickness of the workpiece is thick, the counter distance L may be increased to match it.

<Guide shaft>

The guide shaft 40 is an axial structure, and upper and lower ends thereof are mounted to the upper guide unit 15 and the lower guide unit 25, respectively, to mechanically connect the upper guide unit 15 and the lower guide unit 25. (FIG. 1, FIG. 15).

Since the lower module 20 is mechanically connected to the upper module 10 by the tool rotation shaft 30 and the guide shaft 40 described above, the upper module 10 may prevent the lower module 20 from falling below the work surface. It serves to pull, the lower module 20 is moved in the same direction and the same speed in conjunction with the movement of the upper module 10 (Fig. 15).

1, the upper end of the guide shaft 40 is mounted in a manner of being fitted into a groove formed in the upper guide unit 15, and the lower end penetrates a hole formed in the lower guide unit 25. It is mounted in such a way that it is inserted.

In this case, the guide shaft 40 preferably has a cross-sectional shape and size substantially equal to the shape and size of the groove formed in the upper guide unit 15 and the hole formed in the lower guide unit 25 so that unnecessary slip does not occur. Do.

On the other hand, in the present invention as described above, the mutually opposed distance between the upper rotary cutter 13a and the lower rotary cutter 23a through the process of adjusting the mounting position of the tool rotation axis 30 of the lower tool unit 23 (Fig. L) of 1 can be adjusted. For this, the mounting position of the lower tool unit 23 with respect to the tool axis of rotation 30 and the mounting position of the lower guide unit 25 with respect to the guide shaft 40 are accompanied.
