The present invention relates to a variety of devices for processing and measuring while maintaining a perpendicular to the horizontal plane, in particular by using an organic coupling between the arm and the timing pulley and the timing belt provided therein or an organic coupling between the sprocket and the chain The work tool, coupled to the extreme end of the arm, relates to the arm vertical holding unit of the machine or measuring instrument, which always provides a vertical view of the ground.

In general, there are many machines, measuring instruments or instruments that must be mounted perpendicular to the ground.

The reason why the thickness gauge of the same product is illustrated in FIG.

That is, in the case of the conventional thickness gauge 1, a support column 3 rotatable in the horizontal direction is attached to the upper portion of the shelf 2, and a horizontal bar horizontal to the shelf surface at the top of the support column 3 ( 4) are combined.

Therefore, in accordance with the condition of the iron plate or component (5) to measure the thickness, the support pillar (3) is pulled back to the upper state, and the horizontal bar (4) is pulled out or inserted into a fixed state exactly In the vertical position, the thickness is measured by a laser emitted from the gauge 6 fixed to the end.

Of course, this operation is limited to the thickness gauge 1 of the type shown, and the majority of the thickness gauges have to be in a state where the verticality is exactly aligned so that the support pillar and the horizontal bar are fixed in such a state that they cannot interlock. Is the majority.

The thickness measuring instrument measures the thickness by moving the steel plate or the parts placed on the shelf in accordance with the gauge fixed to the end of the horizontal bar.

Therefore, such a thickness gauge has many problems.

First, in the case of the measuring device 1 configured such that the support column 3 and the horizontal bar 4 can be interlocked, there is a hassle to pull out the support column 3 and the horizontal bar 4 and use the horizontal. In the extended state of the bar 4, the verticality thereof is not exactly matched, so that the accuracy of the gauge 6 may be poor.

Second, in order to interlock to adjust the support column (3) and the horizontal bar (4), it is necessary to loosen and retighten the adjusting mechanism (7), which results in a time-consuming process for the measurement. .

Third, in the case of the measuring device 1 in which the supporting column and the horizontal bar are completely fixed, it is cumbersome to measure the thickness of each part by moving the iron plate or the parts placed on the shelf.

In addition, if foreign matter is caught between the iron plate or the part and the shelf during the movement of the iron plate or the part, the measurement of the thickness may result in inferior accuracy.

In addition, the thickness measuring device of the above-described type is only one embodiment of a processing machine or measuring device that must be perpendicular to the horizontal plane, and there exist many types of processing machines or measuring devices that must always be perpendicular to the horizontal plane.

Machines that make holes using drills should always be perpendicular to the ground, and welders for joining should always be perpendicular, and many other types of machines or measuring instruments should always be perpendicular to the ground. There are many things that can only be done.

However, it was judged that there was no measuring device or processing machine that could freely interlock and could always maintain the vertical without any additional work.

The present invention, which solves the above-mentioned problems, relates to various apparatuses for processing and measuring while maintaining perpendicular to a horizontal plane. Work tools coupled to the extreme end of the arm using organic bonding are intended to provide an arm holding unit of the machine or measuring instrument that always faces the ground vertically.

Therefore, the present invention, the inside of the bracket fixed to one side of the body, the first timing pulley fixed with the bracket; A hollow first arm incorporating the first timing pulley; A third timing pulley fixed to the same axis as the second timing pulley embedded in the end of the first arm and rotating through the axis; A hollow second arm incorporating the third timing pulley; A fourth timing pulley rotatably fixed to an end of the second arm; A work tool fixed perpendicularly to the fourth timing pulley; The first timing pulley and the second timing pulley are connected with a first timing belt, and the third timing pulley and the fourth timing pulley are connected with a second timing belt, and the first timing pulley has a bracket inside the first arm. The remaining timing pulley is intended to provide an arm holding unit of the machine or measuring machine which rotates under the action of the belt.

It is also an object of the present invention to provide an arm vertical holding unit of a processing machine or a measuring machine which can achieve the timing pulley and belt of the above-described configuration through a sprocket and a chain.

In addition, the present invention is to provide an arm vertical maintenance unit of the processing machine or measuring device that can be composed of three to seven multi-stage arms by connecting the pulley, the arm and the sprocket and the chain at the end of the second arm described above.

The object of the present invention is similar to that of the related art in that the present invention is a variety of apparatuses for processing and measuring while maintaining a perpendicular to the horizontal plane.

However, even if you change the position of the work tool fixed to the end by interlocking the arms, it is always perpendicular to the horizontal plane, and it is easy to work or measure accordingly, and thus can be applied to various measuring instruments, instruments, and machines. Since there is a great feature in that it will be described in detail the configuration and operation with the drawings shown.

2 to 6, the present invention has a first timing pulley 10 fixed to the bracket 11 inside the bracket 11 fixed to one side of the body; There is a hollow first arm 12 having the first timing pulley 10 embedded therein.

A second timing pulley (30) fixed to the same shaft (13) as the second timing pulley (20) embedded in the end of the first arm (12) and rotating through the shaft (13); A hollow second arm 31 having the third timing pulley 30 embedded therein is formed.

There is also a fourth timing pulley 40 rotatably fixed to the end of the second arm 31; The work tool 45 fixed to the fourth timing pulley 40 is vertically provided.

Therefore, the first timing pulley 10 and the second timing pulley 20 are connected to the first timing belt 16, and the third timing pulley 30 and the fourth timing pulley 40 are second timing belts. The first timing pulley 10 is fixed to the bracket 11 inside the first arm 12, but the remaining timing pulley is rotated by the action of the belt.

That is, as shown in FIGS. 3 and 4, a first arm 12 is hinged to the bracket 11 that is opened upward, and an axis A of the first timing pulley 10 is formed inside the first arm 12. ) Is fastened to the bracket (11).

More precisely, the axis A of the first timing pulley 10 is completely fixed to the bracket 11, but the first arm 12 is the axis A of the first timing pulley 10. ) Is rotatable.

Although not shown, the first arm 12 may be hinged to the fixed axis A for organic coupling with the axis A of the first timing pulley 10 of the first arm 12. In order to make the shaft hole rotate easily, a separate bearing may be installed.

And inside the other side of the first arm 12 there is a second timing pulley 20 coupled via the shaft 13.

The second timing pulley 20 has the same shape as the first timing pulley 10 described above and has the same size and the same pitch, but there is a difference in that the second timing pulley 20 is rotatable.

That is, the above-described first timing pulley 10 has a shaft A completely fixed to the bracket 11, but the second timing pulley 20 is rotatable by being fitted into the other shaft hole of the first arm 12. It is.

Of course, although not shown for organic coupling between the shaft 13 of the second timing pulley 20 and the shaft hole of the first arm 12, a bearing may be mounted.

In addition, as shown in FIG. 4, the shaft 13 of the second timing pulley 20 has an integral shape that is the same axis as the axis of the third timing pulley 30, and a third timing pulley on the side of the second timing pulley 20. The 30 is fixed and the 2nd arm 31 which wraps the 3rd timing pulley 30 from the outside is comprised.

Here, to describe the organic coupling relationship between the second timing pulley 20, the third timing pulley 30, and the second arm 31, the second and third timing pulleys 20 and 30 may rotate the shaft 13. The second arm 31 is coupled to the third timing pulley 30 through the shaft hole.

That is, the shaft hole of the second arm 31 is wider than the outer circumferential diameter of the shaft 13, and a bearing, not shown, can be mounted for the organic rotatable coupling between the shaft 13 and the second arm 31. May be combined in the state.

In other words, the coupling between the second timing pulley 20 and the first arm 12 and the coupling between the third timing pulley 30 and the second arm 31 are identical.

In addition, a fourth timing pulley 40 is coupled to the other end of the second arm 31, and the work tool 45 shown is coupled to the fourth timing pulley 40, which is viewed vertically from the ground. Are combined.

Of course, at this time, the coupling between the shaft hole of the second arm 31 and the fourth timing pulley 40 is also larger in diameter than that of the shaft B of the fourth timing pulley 40, and a bearing is mounted therein. By considering the arm can be easily interlocked.

The first to fourth timing pulleys 40 are connected to the first timing belt 16 and the second timing belt 17.

Anyway, the configuration of the present invention is combined, as described above, and the operation thereof is as follows.

Referring first to the features of the present invention, the present invention may be conceptual.

That is, the same action as the present invention can be achieved by organic combination of various components.

Therefore, in the present invention, description of the detailed configurations is avoided as much as possible.

The reason is that there are many combinations between various types of configuration requirements that can pursue the concept of the present invention.

In the present invention, only the essential components capable of achieving the technical idea are described in a manner of describing all, and more specific embodiments will be created later.

Anyway, the operation of the first timing pulley 10, the second timing pulley 20, and the first arm 12 will be described through the exemplary operation of FIG. 2.

First, when the first arm 12 of FIG. 2 is held and descends downward, the first arm (A) of the first timing pulley 10 is fixed to the bracket 11 as shown. The shaft hole of 12) rotates on the outer circumferential surface by using the shaft A of the first timing pulley 10 as a fixed hinge.

Of course, this action will act as a vertical linkage of the first arm (12).

In addition, the second timing pulley 20 is fixed to the other end of the first arm 12 in a rotatable state, and the work tool 45 is rotated in the same manner as the rotation of the second timing pulley 20. It is fixed and coupled to the ground in the vertical direction.

Therefore, the interlocking operation of the first arm 12 moves the first timing belt 16 connecting the first timing pulley 10 and the second timing pulley 20 to the left and right so that the second timing pulley ( 20) in the direction of the arrow shown.

As a result, even when the first arm 12 is interlocked, the second timing pulley 20 is rotated by the interlocking angle so that the work tool 45 coupled to the second timing pulley 20 maintains the direction perpendicular to the horizontal plane. It is.

Of course, this action also works the same as raising the first arm 12 in the reverse direction.

That is, the second timing pulley 20 is rotated in the direction opposite to the arrow direction of FIG. 2 to maintain the combined working tool 45 at right angles to the horizontal plane.

Furthermore, as shown in FIG. 3, when the second arm 31 operates the vertical holding unit as the first embodiment of the present invention in which the second arm 31 overlaps with the first arm 12, the following operation is performed.

Here, the third timing pulley 30 using the same shaft 13 as the shaft 13 of the second timing pulley 20 is embedded in the second arm 31.

Therefore, when only the second arm 31 is interlocked up and down in a state where the first arm 12 is not operated, the second arm 31 moves downward while interlocking as shown in FIG. 3.

At this time, the shaft hole of the second arm 31 is larger in diameter than the shaft 13 of the second and third timing pulleys 20 and 30, and only the second arm 31 is interlocked with the shaft 13 fixed. do.

More precisely, the second and third timing pulleys 20 and 30 embedded in the second arm 31 and the first arm 12 are connected to the first timing belt 16 to the fixed first timing pulley 10. Rotation is fixed because it is connected.

Therefore, only the second arm 31 is interlocked up and down, and the second timing belt 17 is interlocked with each other by the distance brought by the linkage.

Of course, the left and right linkage of the second timing belt 17 has no choice but to rotate the fourth timing pulley 40 in the direction of the arrow to compensate for the linkage length.

The reason is that since the second and third timing pulleys 20 and 30 are connected through the fixed first timing pulley 10 and the first timing belt 16, the rotation thereof is stopped.

Accordingly, the fourth timing pulley 40 rotates in the reverse direction in the direction of the arrow of the drawing as shown by the interlocking angle of the second arm 31 so that the work tool 45 fixed to the fourth timing pulley 40 is always in the horizontal plane. Is to maintain the right direction.

Furthermore, even if the first arm 12 and the second arm 31 are vertically interlocked together and interlocked at different angles and directions, the work tool is always perpendicular to the horizontal plane by compensating through the pulleys and belts. Can be maintained in the direction of.

In the vertical holding unit of the present invention, as shown in Fig. 4, the bracket 11 fixed to one side of the base has a horizontal rotating hinge 38 therein.

Therefore, the vertical holding unit of the present invention can be rotated in the horizontal direction to process and measure any article or steel plate, even if it is placed on any position on the shelf in the horizontal state is easy to process or measure.

On the other hand, the concept of the present invention, as shown in Figure 5, the end of the second arm 31, it may be composed of three to seven multi-stage arms by connecting the pulley and the arm.

That is, no matter how many arms are connected, the working tool of the end is always kept vertical to the horizontal plane because the operation of the present invention is always maintained the same.

And unlike the first embodiment described above, as shown in Figure 6 shown in the present invention, all the configuration is the same, but may be manufactured by replacing the timing pulley with a corresponding chain with the timing pulley sprocket.

That is, as shown in Figs. 6 and 7, in the second embodiment of the present invention, inside the bracket 61 fixed to one side of the base, the bracket 61 and the first sprocket 60 are fixed; A hollow first arm 62 having the first sprocket 60 therein is formed.

There is also a third sprocket (80) fixed to the same axis (63) as the second sprocket (70) embedded in the end of the first arm (62) and rotates through the axis (63); A hollow second arm 81 having the third sprocket 80 therein is formed.

There is also a fourth sprocket (90) rotatably fixed to the end of the second arm (81); The fourth sprocket 90 is provided with a work tool 95 fixed perpendicularly to a horizontal plane.

Accordingly, the first sprocket 60 and the second sprocket 70 are connected to the first chain 66, and the third sprocket 80 and the fourth sprocket 90 are connected to the second chain 67. The first sprocket 60 is fixed to the bracket 61 inside the first arm 62, but the remaining sprocket rotates by the action of the chain.

That is, although the configuration is the same as the first embodiment described above, except that the pulley and the timing belt is replaced with the sprocket and the chain, the operation is also the same.

In addition, the present invention of the second embodiment, that is, the bracket 61 fixed to one side of the base, it is also configured to be configured to rotate 360 degrees in the horizontal direction by forming a horizontal rotation hinge 88 therein.

In addition, in the case of the second embodiment of the present invention, the end of the second arm 81, it may be composed of three to seven multi-stage arms by connecting the sprocket and the arm.

As described above, the present invention is easy to use because it can be applied to a variety of machines, measuring instruments and measuring instruments to always maintain the work tool perpendicular to the horizontal plane.

In addition, the present invention is a simple structure, but can be changed to any position, even if the position change work tool always maintains a vertical state with the horizontal plane and does not require a separate position fixing means.

In addition, the present invention can be measured and processed by directly moving through the bent arm without moving the goods or materials requiring measurement or processing, so that the time for the work is fast, and as a result, the production yield and the cost reduction can be improved.
