In particular, the transport frame 20 is formed on the fixed frame 10 is preferably provided to be directly supported by the fixed frame 10. The transfer frame 20 may be formed larger than the fixed frame 10, but is preferably formed as small as possible. This is to prevent damage due to the pressing force of the horizontal feed rail 110 and the horizontal feed guide 120 interposed between the fixed frame 10 and the transport frame 20. The transfer frame 20 is capable of linear reciprocating movement in the horizontal direction with respect to the fixed frame 10 during the operation of the horizontal feed operation unit 100 on the fixed frame 10. The transfer frame 20 may be made of various shapes and various materials.

Here, the "horizontal direction" means the "X" axis direction on the plane.

In addition, the transport frame 20 connects the subframe 30. This subframe 30 is formed on the transfer frame 20. Thus, the subframe 30 is reciprocally moved in the horizontal direction along with the simultaneous transport frame 20, the horizontal feed operation unit 100, the slide frame is provided to be able to slide transfer in the vertical direction.

In this case, the subframe 30 may be formed to a size that covers the entire upper side of the transport frame 20, but is preferably formed to the smallest possible size to reduce the driving force required to transport. For convenience, the subframe 30 is formed in two pieces and is shown to be formed on each side edge corresponding to the transverse direction of the transport frame 20, respectively.

Here, the subframe 30 is capable of linear reciprocating movement in the vertical direction with respect to the feed frame 20 during the operation of the vertical feed operation unit 200 on the transfer frame 20. The subframe 30 may be made of various shapes and various materials.

Here, the "vertical direction" refers to the "Y" axis direction perpendicular to the "horizontal direction" on the plane.

In particular, while the horizontal feed operation unit 100 and the vertical feed operation unit 200 operates independently to guide the multi-directional reciprocating rotation device 300 in a multi-directional reciprocating rotation. Here, the multi-directional rotating device 300 connects and supports the welding torch rod (5).

That is, the horizontal feed operation unit 100 can adjust the inclination direction and the inclination angle of the torch rod 5 by reciprocating the transport frame 20 and the subframe 30 to the fixed frame 10 in the horizontal direction. As a result, the lower side of the torch rod 5 can be reciprocated in the horizontal direction.

The transverse rail 110 is fixedly formed on the upper side of the fixed frame 10 by various methods such as bolting or welding.

Then, the horizontal feed guider 120 is fixed to the lower side of the transfer frame (20). At this time, the horizontal feed guide 120 is guided reciprocating slide transport along the horizontal feed rail (110). In particular, since the horizontal feed guide 120 is supported on the horizontal feed rail 110, the transport frame 20 is supported on the fixed frame (10). Here, the horizontal feed rail 110 and the horizontal feed guide 120 is preferably a conventional LM guide.

Of course, the horizontal feed guide 120 is fixed to the upper side of the fixed frame 10 and the horizontal feed rail 110 may be fixed to the lower side of the transport frame 20.

In addition, the horizontal transfer motor 130 is fixed to the transfer frame 20 is driven when the external power is applied.

In particular, the horizontal feed motor 130 is preferably mounted to the transfer frame 20 by a bracket or the like. Of course, the horizontal feed motor 130 may be fixedly mounted on the fixed frame (10).

In addition, the horizontal feed pinion gear 140 is directly connected to the horizontal feed motor 130. Thus, when the horizontal feed motor 130 is driven, the horizontal feed pinion gear 140 is reciprocally rotated in one direction and the other direction by receiving the driving force of the horizontal feed motor 130. That is, the horizontal feed pinion gear 140 performs a rotational motion. The horizontal feed pinion gear 140 is connected to the horizontal feed motor 130 is a general method.

Then, the horizontal feed rack gear 150 is formed in the fixed frame 10, the gear is coupled to the horizontal feed pinion gear 140. In particular, the horizontal transfer rack gear 150 is fixedly mounted in the horizontal direction on the fixed frame (10). That is, the horizontal transfer rack gear 150 is fixed to the fixed frame 10 by a method such as bolting or welding. At this time, since the fixed frame 10 is fixedly installed, the horizontal transfer rack gear 150 is also fixed.

Therefore, when the horizontal feed motor 130 is driven, the horizontal feed pinion gear 140 is rotated in one direction or the other direction. At this time, since the horizontal feed rack gear 150 is fixed, the horizontal feed pinion gear 140 rotates and linearly reciprocates along the axial direction (horizontal direction) of the horizontal feed rack gear 150. As a result, the transfer frame 20 is capable of linear reciprocating movement in the horizontal direction with respect to the fixed frame 10.

Here, when the horizontal feed pinion gear 140 and the horizontal feed rack gear 150 are able to withstand the load applied by the gear coupling, the horizontal feed rail 110 and the horizontal feed guide 120 is unnecessary.

Of course, the horizontal feed operation unit 100 may apply a variety of configurations.

In addition, as an example, the vertical feed operation unit 200 includes a vertical feed rail 210, a vertical feed guide 220, a vertical feed motor 230 and the gear unit 240.

In particular, the subframe 30 is arranged side by side in the longitudinal direction inside the transport frame 20, the vertical transport rail 210 is formed on the outside of each of the subframe 30, in particular, the subframe 30. At this time, the axial direction of the vertical transfer rail 210 is disposed parallel to the longitudinal direction. In addition, the vertical transfer rail 210 is fixedly formed on the outer side of the subframe 30 by various methods such as bolting or welding.

In addition, the vertical feed guide 220 is fixedly formed inside the transfer frame 20. At this time, since the conveying frame 20 is provided so as not to reciprocate in the longitudinal direction with respect to the fixed frame 10, the longitudinal conveying rail 210 is guided reciprocating slide conveyance along the longitudinal conveying guide 220. Here, the vertical feed rail 210 and the vertical feed guide 220 is preferably a conventional LM guide.

Of course, the vertical feed guide 220 is fixedly formed on the circumferential surface of the subframe 30 and the vertical feed rail 210 is fixedly formed on the circumferential surface of the transfer frame 20 to correspond to the vertical feed guide 220. It may be.

In addition, the vertical transfer motor 230 is fixed to the transfer frame 20 is driven when the external power is applied. The vertical feed motor 230 is a various driving source, it is preferable to use a stepping motor. In particular, the vertical transfer motor 230 is preferably mounted to the transfer frame 20 by a bracket or the like. Of course, the vertical transfer motor 230 may be fixedly mounted on the fixed frame 10 or the subframe 30.

In addition, the driving force of the vertical transfer motor 230 is transmitted to the subframe 30 through the gear unit 240, the subframe 30 is capable of linear reciprocating movement in the vertical direction through the rotational force of the gear unit 240. do.

For example, the gear unit 240 is a vertical feed gear 241, a vertical driven gear 242, a vertical feed driven shaft 243, a vertical feed driven shaft 244, a vertical feed idle shaft 246, a vertical feed And a pinion gear 248 and a vertical transfer rack gear 249.

The vertical feed main gear 241 is directly connected to the vertical feed motor 230 and rotates freely drawing a circle trajectory in one direction and the other direction when the vertical feed motor 230 is driven. The vertical transfer main gear 241 is connected to the vertical transfer motor 230 is a general one.

In addition, the vertically driven driven gear 242 is gear-coupled to circumscribe the vertically driven main gear 241. Thus, the vertically driven driven gear 242 rotates in the opposite direction to the vertically driven main gear 241.

In addition, the vertically driven driven shaft 243 is disposed parallel to the 'X' axis in the transport frame 20, and is rotatably supported by the transport frame 20. In particular, the vertically driven driven shaft 243 is preferably supported by being rotatably inserted into the bracket fixedly mounted on the transport frame (20).

In addition, the longitudinally driven driven shaft 243 is axially inserted into the longitudinally driven driven gear 242. Thus, the longitudinally driven driven gear 242 is supported by the longitudinally driven driven shaft 243. At this time, the vertically driven driven gear 242 rotates together with the vertically driven driven shaft 243 as it is fixed to the vertically driven driven shaft 243. The vertically driven driven gear 242 is fixed to the vertically driven driven shaft 243 may be variously modified, such as a pin coupling.

In addition, the vertical feed driven shaft 244 is disposed parallel to the 'Y' axis in the transport frame 20, it is rotatably supported by the transport frame (20). In particular, the vertical feed driven shaft 244 is preferably supported by the shaft is rotatably inserted into the bracket fixedly mounted on the transfer frame 20.

The vertical feed driven shaft 244 and the vertical feed driven shaft 243 are connected to the first connecting gear member 245. Thus, the longitudinally driven driven shaft 244 receives a rotational force from the longitudinally driven driven shaft 243. At this time, since the longitudinal feed driven shaft 244 and the vertical feed driven shaft 243 are perpendicular to each other, the first connection gear member 245 is preferably a bevel gear. Of course, the first connection gear member 245 may apply a gear of various shapes.

In particular, the vertically driven driven shaft 243 may connect the vertically driven driven shaft 244 to only one side, but the vertically driven driven shaft may be vertically moved on both sides so that each of the pair of subframes 30 facing each other may be simultaneously moved in the same direction. Connect (244).

Accordingly, the longitudinal feed driven shaft 244 is shown to be provided with a pair side by side in the longitudinal direction.

In addition, the vertical feed driven shaft 244 is connected to the vertical feed idler shaft 246, respectively. The vertical feed idler shaft 246 is rotatably supported by the transfer frame 20 or the vertical feed guider 220. That is, the vertical feed idler shaft 246 is rotatably supported by a bracket formed on the transfer frame 20 or the vertical feed guider 220. For convenience, the vertical feed idler shaft 246 is illustrated as being supported by the vertical feed guider 220, but may be positioned in various positions and supported in various shapes.

In particular, since the vertical feed driven shaft 244 and the vertical feed rail 210 are arranged side by side in the vertical direction, the vertical feed idler axis 246 serves to connect the vertical feed driven shaft 244 and the vertical feed rail 210. do. That is, the vertical feed idler shaft 246 connects one side with the vertical feed driven shaft 244 and the other side with the vertical feed rail 210.

In more detail, one side of the vertical feed idler shaft 246 is connected by the vertical feed driven shaft 244 and the second connecting gear member 247. Here, the second connection gear member 247 may be applied to various power transmission elements, but the bevel gear is preferable because the power transmission direction is converted to the vertical direction.

The other side of the vertical feed idler shaft 246 forms a vertical feed pinion gear 248. The vertical feed pinion gear 248 is integrally formed on the vertical feed idler shaft 246 or detachably formed and fixed to the vertical feed idler shaft 246 to rotate in the same direction.

In addition, the vertical feed pinion gear 248 is coupled to the vertical feed rack gear (249). In particular, the vertical feed rack gear 249 is fixedly formed on each subframe 30, and is gear-coupled with the vertical feed pinion gear 248.

Accordingly, when the vertical feed pinion gear 248 rotates with the fixed vertical feed idler shaft 246, the vertical feed rack gear 249 reciprocates in the vertical direction. Accordingly, the subframe 30 is capable of reciprocating in the longitudinal direction together with the vertical transfer rack gear 249.

Of course, the vertical feed operation unit 200 and the gear unit 240 may be applied in various configurations within the upper surface area allowed by the transfer frame 20 and the subframe 30.

On the other hand, when the horizontal feed operation unit 100 and the vertical feed operation unit 200 operates independently, the welding torch rod 5 is connected to the horizontal feed operation unit 100 and the vertical feed operation unit 200. Supported by the direction turning device 300 is guided in a multi-directional reciprocating rotation.

Here, the multi-direction means all directions including four directions.

For example, referring to FIG. 4, the multidirectional pivoting device 300 includes a pivot pin 310, a link arm 320, a main connecting rod 330, a sub-connecting rod 340, an upper restraining unit 350, and The lower constraining part 360 is included.

The pivot pin 310 is formed to be bidirectionally rotated on the fixed frame 10. In addition, the pivot pin 310 is provided in pairs on the same central axis.

That is, the fixed frame 10 has a space communicating with the upper and lower, the empty space of the fixed frame 10 has a substantially rectangular shape on the plane, the pivot pin 310 is inside the empty space of the fixed frame 10 Is formed rotatably on the inner side facing each other. In particular, the pivot pin 310 is rotatably inserted into the fixed frame (10). Here, the opposite pivot pins 310 are positioned on the central axis. In addition, the pair of pivot pins 310 are positioned in a straight line in the longitudinal direction. The pivot pin 310 may be formed in various shapes. Of course, the pivot pin 310 may be made in various numbers.

In addition, a link arm 320 is formed on each pivot pin 310. Thus, each link arm 320 is located at the corner of the rectangular trajectory on the plane. In particular, each of the link arms 320 is hinged rotatably in the horizontal direction along the arc trajectory to the corresponding pivot pin 310. In this case, the link arm 320 is preferably pin-connected to the pivot pin 310 is hinged to be rotated in the horizontal direction. Here, each of the link arms 320 is hinged to the lower side to the corresponding pivot pin 310.

Therefore, each of the link arms 320 is pivotally coupled to the pivot pin 310 as the pivot pin 310 is axially coupled to the fixed frame 10 and rotates along the arc trajectory. It is possible to reciprocate in the horizontal direction along the trajectory.

In addition, the pair of link arms 320 positioned on the same central axis of the pivot pin 310, in particular, in a horizontal direction in a straight line is constrained from each other, and the pair of link arms 320 located in a straight line in the longitudinal direction. Are preferably bound to each other.

That is, the pair of link arms 320 positioned on the same central axis of the pivot pin 310 are hinged to the main connecting rod 330. Thus, the main connecting rod 330 is provided in a pair. In particular, the main connecting rod 330 serves to rotate the constrained link arm 320 together in the same transverse direction.

In addition, the pair of link arms 320 corresponding to the same central axis of the pivot pin 310 are hinged to the sub-connecting rod 340. Thus, a pair of sub-connecting rod 340 is provided.

In this case, the height of the main connecting rod 330 hinged to the link arm 320 and the height of the sub-connecting rod 340 hinged to the link arm 320 are different. That is, the link arm 320 makes the portion connected to the main connecting rod 330 higher than the portion connected to the sub connecting rod 340.

Here, the main connecting rod 330 and the sub connecting rod 340 are maintained in parallel. In particular, to hinge the pair of link arms 320 located on the same central axis of the pivot pin 310, the sub-connecting rod 340 is hinged to one of the link arms 320 and At the same time, the other side is hinged to one other link arm 320, or one side is hinged to any one link arm 320 and at the same time the other side is made of a pair of link connecting to the main connecting rod 330.

Meanwhile, the reason why a pair of sub-connecting rods 340 are provided to be arranged on the same central axis is to avoid interference with the upper ribs 352, which will be described later. For convenience, the sub-connecting rod 340 is shown as a pair provided on the same central axis.

In addition, an end portion of each sub-connecting rod 340 arranged on the same central axis is hingedly connected to the main connecting rod 330 positioned at the top by a connecting pin 342. The connecting pin 342 is hinged to the main connecting rod 330 and the sub connecting rod 340 is a general method.

Accordingly, the sub-connecting rod 340 moves in the same direction as the main connecting rod 330. In addition, since the link arm 320 forms a higher hinge portion of the main connecting rod 330 than the sub connecting rod 340, the movement trajectory of the main connecting rod 330 is the movement trajectory of the sub connecting rod 340. Will be different. That is, when the link arm 320 is inclined, the moving distance of the main connecting rod 330 is farther than the moving distance of the subconnecting rod 340.

In addition, the pair of main connecting rods 330 parallel to each other is interlocked by the same trajectory, and is preferably connected to the restraining member 332 to maintain a horizontal state during movement. The restraining member 332 may be deformed into various shapes and fixedly coupled to each of the main connecting rods 330 by various methods.

In addition, each of the link arms 320 reciprocates with respect to the pivot pin 310 corresponding to each other by the pushing or pulling force of the subframe 30 which is moved in the longitudinal direction, so that the sub-connecting rod 340 is interlocked with the link member. It is preferred to be connected to the corresponding link arm 320 by 344. That is, the link arm 320 rotates in the longitudinal direction along the arc path, and the sub-connecting rod 340 reciprocates in the longitudinal direction on the same plane. Thus, the interlocking member 344 serves to maintain the connection state of the link arm 320 and the sub-connecting rod 340 at all times while corresponding to the positional change of the link arm 320 and the sub-connecting rod 340. At this time, the interlocking member 344 is preferably LM guide.

On the other hand, the torch rod 5 is connected to the upper restraint portion 350 supported by the main connecting rod 330. Thus, the torch rod 5 is moved by the moving distance of the main connecting rod 330 connected to the link arm 320. In particular, the torch rod 5 is inclined in the same direction as the link arm 320 by the upper restraint unit 350.

As an example, the upper restraint unit 350 includes an upper rib 352, an upper outer ring 354, and an upper inner ring 356.

The upper rib 352 extends downward in parallel with each other in each of the main connecting rods 330 parallel to each other. Of course, since the pair of main connecting rods 330 are restrained from each other by the restraining member 332, the upper ribs 352 connected to the respective main connecting rods 330 are restrained from each other.

The upper outer ring 354 is hinged to the lower side of the upper rib 352. That is, the upper outer ring 354 hingedly connects each of the upper ribs 352 to the opposite outer side.

In addition, the upper inner ring 356 is rotatably connected inside the upper outer ring 354. That is, the upper inner ring 356 is hinged at two points with the upper outer ring 354 in a direction perpendicular to a straight line connecting the portion connected to the upper rib 352. At this time, the upper inner ring 356 is fixed to the welding torch rod (5) by a variety of ways. Therefore, the torch rod 5 is rotated based on the connection portion of the upper outer ring 354 and the upper inner ring 356. In particular, the torch rod 5 is connected to the upper inner ring 356 in various ways.

On the other hand, the torch rod 5 is connected to the lower restraining part 360 supported by the sub-connecting rod 340. Thus, the torch rod 5 is moved by the movement distance of the sub-connecting rod 340 connected to the link arm 320 located in a straight line in the longitudinal direction. In particular, the torch rod 5 is inclined in the same direction as the link arm 320 by the lower restraining part 360.

As an example, the lower constraining portion 360 includes a lower rib 362, a lower outer ring 364, and a lower inner ring 366.

The lower ribs 362 extend in parallel with each other in each of the sub-connecting rods 340 adjacent to each other in a direction perpendicular to the axial direction of the main connecting rod 330, in particular, in a longitudinal direction. That is, the lower rib 362 serves to restrain the sub-connecting rod 340 adjacent in the vertical direction. The method of connecting the lower rib 362 to the sub-connecting rod 340 may be variously modified, such as pin coupling.

The lower outer ring 364 is hinged to the lower side of the lower rib 362. That is, the lower outer ring 364 hingedly connects each of the lower ribs 362 to the opposite outer side.

At this time, any line connecting the connection portion of the upper outer ring 354 with the opposing upper rib 352 and the line connecting the connection portion of the lower outer ring 364 with the opposing lower rib 362 are vertical. .

In addition, a lower inner ring 366 is rotatably connected to the lower outer ring 364. That is, the lower inner ring 366 is hinged at two points with the lower outer ring 364 to be perpendicular to the straight line connecting the lower rib 362. At this time, the lower inner ring 366 is fixed to the welding torch rod (5) by a variety of ways. Therefore, the torch rod 5 is rotated based on the connection portion of the lower outer ring 364 and the lower inner ring 366. In particular, the torch rod 5 is connected to the lower inner ring 366 in various ways.

In particular, the upper rib 352 and the lower rib 362 is connected to the upper rib 352 to the main connecting rod 330 which varies the moving distance as the link arm 320 is inclined, and at the same time the sub-connecting rod 340 Is connected to the lower rib 362.

At this time, the moving distance of the main connecting rod 330 is farther than the moving distance of the sub-connecting rod 340 with respect to the vertical direction or the horizontal direction with respect to the lower side of the link arm 320. In addition, the upper rib 352 and the lower rib 362 is moved in the same direction. Thus, the upper rib 352 moves linearly farther than the lower rib 362.

Therefore, the torch rod 5 is inclined in the same direction as the tilt direction and the tilt angle of the link arm 320. Here, the upper outer ring 354 and the upper inner ring 356 and the lower outer ring 364 and the lower inner ring 366 serves to support and guide the inclined torch rod (5).

Referring to FIGS. 5, 6, and 7, when the user applies an operation signal to the horizontal feed motor 130 in the initial state (see FIG. 1) in which the torch rod 5 is standing, the horizontal feed pinion The gear 140 rotates counterclockwise, and at the same time, the transport frame 20 and the subframe 30 are moved along the horizontal transport rack gear 150 fixed to the fixed frame 10 in the '+ X' direction. Will be moved to.

Therefore, the link arm 320 is inclined in the horizontal direction to the upper right (refer to the drawing) in the state connected to the fixed frame 10.

Then, the main connecting rod 330 and the sub-connecting rod 340 are moved in the '+ X' direction while being horizontal to each other by the inclination of the link arm 320.

In this case, the main connecting rod 330 has a longer moving distance than the sub connecting rod 340. Thus, the torch rods 5 are supported inclined upwardly upward because the moving distance of the upper rib 352 is longer than the moving distance of the lower rib 362. In particular, the inclination angle and the inclination direction of the link arm 320 are the same as the inclination angle and the inclination direction of the torch rod 5.

The reference numerals not described are replaced with those described above.

3 and 8, when the user applies the operation signal to the vertical feed motor 230 in the initial state (see FIG. 1) where the torch rod 5 is standing, the vertical feed pinion gear 248 is clockwise. While rotating in the gearbox coupled to the vertical transfer rack gear 249 fixed to the subframe 30 is moved in the '+ Y' direction.

At the same time, the subframe 30 moves in the '+ Y' direction with respect to the transport frame 20.

Therefore, the link arm 320 is inclined in the vertical direction to the right (refer to the drawing) in a state in which the lower side is connected to the fixed frame 10.

In this case, the main connecting rod 330 has a longer moving distance than the sub connecting rod 340. Thus, the torch rod 5 is inclined upwardly and upwardly in the longitudinal direction because the moving distance of the upper rib 352 is longer than that of the lower rib 362. In particular, the inclination angle and the inclination direction of the link arm 320 are the same as the inclination angle and the inclination direction of the torch rod 5.

The reference numerals not described are replaced with those described above.

Of course, although not shown, when the vertical feed pinion gear 248 rotates counterclockwise, the link arm 320 is rotated clockwise through the above-described configuration and process while moving in the '-Y' direction at the same time It will be tilted upward to the left.

Meanwhile, FIG. 9 illustrates a state in which the torch rod 5 is inclined in the '+ X- + Y' direction while the horizontal feed motor 130 and the vertical feed motor 230 are simultaneously driven.

The reference numerals not described are replaced with those described above.
