BACK TILTABLE WELDING POSITIONER APPARATUS AND TIG WELDING SYSTEM BACK TILTING WELDING POSITIONING APPARATUS AND TIG WELDING SYSTEM

The present invention relates to a welding positioner apparatus and a tig welding system, and more particularly, to a back tilting welding positioner apparatus and a tig welding system including the same.

In general, welding means welding two or more objects or materials into a molten or semi-molten state, and then joining the materials (welding rod and wire) to the welding process. Various welding methods are used depending on the type and thickness of the material.

There have been various kinds of welding methods that indirectly join welding by adding a welding rod to a welded part between two objects called a base material or a certain part of an object. Among them, a special torch (TIG) welding that does not dissolve by the arc heat, that is, the electrode used as the heat source, that is, the welding electrode is welded while supplying the inert gas to the welding part through the electrode bar supporting device, . TIG welding is divided into manual welding according to the welding method, semiautomatic welding in which the feeding of the lubricant is mechanically automatic feeding and manual operation of the torch only, supply of the consumable material and automatic welding for automatically controlling the welding progress.

On the other hand, a welding positioner device is used in order to ensure the safety of welding of large pipes and to easily arrange a large pipe to a desired position to satisfy the welding posture requirements. When a welding positioner device is used, the welding base material is rotated at a desired speed and efficient welding becomes possible.

In the case of the conventional welding positioner, the table on which the welding base material is mounted is tilted forward to a vertical position in a state of being horizontally oriented so that welding can be performed at a desired inclination.

However, as the welding positioner apparatus is applied to the tig welding robot system, the welding of the pipe-type welding base material such as a large pipe or a large nozzle is not performed in a range from a horizontal state to a vertical state, There is also a need for this. That is, it may be necessary to maximize the speed or efficiency of machine welding or automatic welding by performing positive tilting toward the front side and back tilting toward the rear side.

1 to 3, a back tilting welding positioner apparatus 100 according to one example comprises a frame unit 110, a tilting unit 120, a transmission gear unit 130 and a turntable unit 140 . For example, in another example, the back tilting welding positioner apparatus 100 may further include a gripper unit 150. [ That is, it is possible to implement an embodiment in which the gripper unit 150 is removed as shown in FIGS.

At this time, the frame unit 110 includes a base frame 111 and a vertical support frame 113. The vertical support frame 113 is vertically installed on the base frame 111 on both sides. The turntable unit 140 is installed on the vertical support frame 113 such that the tilting unit 120 is installed on the side and the vertical support frame 113 is supported.

The tilting unit 120 is installed on one vertical support frame 113 and provides tilting power. The tilting power is a power for tilting the turntable unit 140.

Next, the transmission gear unit 130 is gear-engaged with the tilting unit 120 as a sector gear, and receives the rotation of the tilting unit 120 to transmit tilting power. At this time, a part of the sector gear of the transmission gear unit 130 protrudes upward from the turntable unit 140 in which the tilting angle is horizontal.

Subsequently, the turntable unit 140 is mounted on the vertical support frame 113 on both sides and is fixedly coupled to one end of the transmission gear unit 130 to be tilted and rotated according to the gear rotation of the transmission gear unit 130 And performs a horizontal table rotation on its own perpendicular to the tilting rotation direction. At this time, the tilting rotary shaft position of the turntable unit 140 is formed higher than the rotary shaft position of the tilting unit 120 gear-coupled with the transmission gear unit 130. In addition, the direction of the horizontal rotation surface of the turntable unit 140 rotates back tilting within a range of 45 degrees to the rear, which is the direction of the side tilting unit 120.

Referring to FIGS. 1 to 3, the details of each configuration of the back tilting welding positioner apparatus 100 will be described. Embodiments of various back tilting welding positioner devices may be implemented according to combinations of implementations of the respective configurations.

Frame unit

Referring to Figs. 1 to 4, the frame unit 110 includes a base frame 111 and a vertical support frame 113. Fig. The base frame 111 is for supporting the vertical support frame 113. For example, the base frame 111 may be formed of a horizontally laid plate or a beam, but is not limited thereto. The vertical support frame 113 is vertically installed on the base frame 111 on both sides. For example, the vertical support frame 113 may include, but is not limited to, a vertically erected plate on the base frame 111.

At this time, the tilting unit 120 may be installed on the vertical support frame 113, for example, on the side surface. Further, the turntable unit 140 is installed to be supported by the vertical support frame 113. That is, the vertical support frame 113 supports the tilting unit 120 that gears (engages) with the transmission gear unit 130 and enables the tilting rotation of the turntable unit 140 by the power of the tilting unit 120 So as to support both sides of the turntable unit 140.

Tilting unit

1 to 3, the tilting unit 120 is installed on one vertical support frame 113 and provides tilting power. The tilting power is a power for tilting the turntable unit 140.

In one example, the tilting unit 120 may include a tilting motor 121 and a worm reducer 123. At this time, the tilting motor 121 supplies rotational force. The worm reducer 123 is installed on one vertical supporting frame 113. At this time, the worm reducer 123 receives the rotational force from the tilting motor 121 and decelerates to provide the tilting power to the coupled sector gear. For example, the timing pulley is provided at one end of the tilting motor 121 and the worm reducer 123, respectively, and the rotational force of the tilting motor 121 can be transmitted to the worm reducer 123 by driving the timing belt and the timing pulley. For example, the tilting motor 121 and the worm reducer 123 are supported on one side of the vertical support frame 113 and can be protected by, for example, a cover box 102a. The worm reducer 123 may include a horizontal screw 123a having a timing pulley at one end thereof and a speed reducer 123b coupled with a horizontal screw and a worm gear so as to decelerate the rotational force transmitted from the tilting motor 121. [ At this time, the pinion gear is provided on one side of the speed reducer coupled with the worm gear, and can be engaged (engaged) with the transmission gear unit 130 described later.

Transmission gear unit

1 to 6, the transmission gear unit 130 is gear-engaged with the tilting unit 120 as a sector gear, and receives the rotation of the tilting unit 120 to transmit tilting power. For example, a part of the sector gear of the transmission gear unit 130 is formed so as to protrude upward from the turntable unit 140 in which the tilting angle is horizontal. The transmitting gear of the positioner apparatus is provided on one side of the lower side of the table which is a tilting target in a semicircular structure. However, in this embodiment, a portion of the sector gear of the transmission gear unit 130 Is formed so as to protrude upward from the turntable unit 140 to be tilted. At this time, the transmission gear unit 130 is fixedly coupled to one side of the turntable unit 140, and the sector gear forms a gear connection with the tilting unit 120.

In one example, the fan-shaped angle of the fan-shaped gear is greater than the sum of the front and rear tilting angles and smaller than the square. At this time, the tilting angle of the fan-shaped transmission gear unit 130 may be within 45 degrees in front and rear directions. Further, in one example, the tilting angle of the fan-shaped transmission gear unit 130 may be within 30 degrees in front and rear, respectively.

For example, the transmission gear unit 130 is protected by the gear cover box 130a coupled to the vertical support frame 113 on the side opposite to the tilting unit 120 side with respect to the vertical support frame 113, .

Turntable unit

1 to 6, the turntable unit 140 is installed to be supported on the vertical support frames 113 on both sides. For example, the rotating shafts of both ends of the turntable unit 140 can be inserted and supported in the through holes formed in the vertical support frames 113 on both sides. Further, the turntable unit 140 is fixedly coupled to one end of the transmission gear unit 130, and is rotated in a tilting manner in accordance with the rotation of the transmission gear unit 130. That is, the rotation shaft is inserted on both vertical support frames 113, and the turntable unit 140 fixedly coupled to one end of the transmission gear unit 130 is tilted and rotated according to the tilting rotation of the transmission gear unit 130.

In addition, the turntable unit 140 performs a horizontal table rotation on itself in a direction perpendicular to the tilting rotation direction. The turntable unit 140 can perform horizontal table rotation based on a tilting rotation according to the tilting rotation of the transmission gear unit 130 and a central axis perpendicular to the tilting rotary shaft. For example, at this time, the turntable unit 140 may be manufactured by fixing the welding base material 200 on the upper part without providing the gripper unit 150 as shown in FIG. 4, The gripper unit 150 can be fixed and the welding base metal 200 can be fixed in the gripper unit 150. [

The tilting rotary shaft position of the turntable unit 140 is formed to be higher than the rotary shaft position of the tilting unit 120 that is gear-coupled with the transmission gear unit 130.

In addition, the direction of the horizontal rotation surface of the turntable unit 140 rotates back tilting within a range of 45 degrees to the rear, which is the direction of the side tilting unit 120. That is, the horizontal rotation surface of the turntable unit 140 is tilted so as to be tilted backward, and the back tilting can be performed within a range of 45 degrees with respect to the vertical position. For example, the turntable unit 140 can also perform forward tilting as in the conventional art. In one example, the tilting angle of the turntable unit 140 may be within 45 degrees in front and rear directions, respectively. Further, in one example, the tilting angle of the turntable unit 140 may be within 30 degrees in front and rear directions, respectively.

Next, with reference to Figs. 1, 2, 3, 5 and / or 6, the turntable unit 140 will be described in detail. In one example, the turntable unit 140 may include two shaft rotation pins 141, a tilting frame 142, a horizontal table unit 143, and a horizontal rotation motor unit 144. Further, in one example, the turntable unit 140 may further include a center pin 145.

Referring to FIGS. 2, 3 and / or 6, the shaft rotation pin 141 is installed so as to pass through the vertical support frames 113 on both sides on the same axis. That is, the two shaft rotation pins 141 have the same axis. 3, both sides of the tilting frame 142 are fixedly coupled to the shaft rotation pins 141 and installed between the vertical support frames 113 on both sides. That is, the tilting frame 142 is disposed between the two vertical support frames 113 so that an intermediate portion between the two side rotary shafts 141 forms a groove 142a lower than the same axis as the rotation axis of the two shaft rotation pins 141 Respectively.

For example, the tilting frame 142 has a plate coupled with one of the shaft rotation pins 141. In this case, in one example, the plate of the tilting frame 142, which is engaged with one shaft rotation pin 141, And is fixedly coupled to one end of the gear unit 130. That is, one end of the transmission gear unit 130 of the fan shape is fixedly coupled to the plate of the tilting frame 142 coupled to the one shaft rotation pin 141, so that the tilting rotation of the transmission gear unit 130 is transmitted to the tilting frame 142 So that the turntable unit 140 can be tilted and rotated at an appropriate angle.

Next, the horizontal table unit 143 will be described with reference to Figs. 2, 3, 5 and / or 6. The horizontal table unit 143 is seated on the groove 142a of the tilting frame 142 so that the same axis between the two shaft rotation pins 141 is penetrated. The tilting frame 142 forms a groove lower than the rotation axis of the two shaft rotation pins 141. At this time, the horizontal table unit 143 is seated on the groove 142a formed by the tilting frame 142 So that the rotational axis of the two shaft rotating pins 141 passes through the horizontal table unit 143. Accordingly, the position of the horizontal table unit 143 can be lowered and stabilized even when the horizontal table rotation is performed together with the tilting rotation. In addition, when the base material 200 for welding is mounted on the upper side of the turntable unit 140 with the center of gravity of the turntable unit 140 being away from the tilting axis, the center of gravity can be positioned close to the tilting axis. That is, when the welding base material 200 is mounted on the gripper unit 150 coupled to the turntable unit 140 to maintain the tilting, the gripper unit 150 and the turntable unit 140, which include the welding base material 200, The center of gravity of the whole body is positioned or brought close to the tilting axis so that the stress to the gear engagement portion between the transmission gear unit 130 and the tilting unit 120 can be reduced according to the tilting rotation.

In addition, the horizontal table unit 143 is tilted according to the tilting rotation of the tilting frame 142. In addition, the horizontal table unit 143 performs horizontal table rotation by horizontal gear rotation.

Further, on the upper side of the horizontal table unit 143, a welding base material 200 may be fixed or a gripper unit 150 for fixing the welding base material 200 as shown in FIGS. 1 to 3 may be fixedly coupled . For example, referring to FIG. 6, there is provided a fixing fixture groove 1143b on the upper side of the horizontal table unit 143, and a fixing bolt 1143b having a T-bolt type fixture So that the welding base material 200 can be directly fixedly coupled to the upper side of the horizontal table unit 143. Alternatively, the gripper unit 150 can be fixedly coupled to the upper side of the horizontal table unit 143 as shown in FIGS.

For example, referring to Figures 3, 5 and 6, the horizontal table unit 143 may include a horizontal rotary gear 143a and a horizontal table 143b in one example . At this time, the horizontal rotation gear 143a is gear-engaged with the horizontal rotation motor unit 144 at the edge. Accordingly, the horizontal rotation gear 143a is rotated in accordance with the rotation of the horizontal rotation motor unit 144. [ The horizontal table 143b is fixed to the upper surface of the horizontal rotary gear 143a and rotates in accordance with the rotation of the horizontal rotary gear 143a. On the upper side of the horizontal table 143b, the welding base material 200 may be directly fixed or the gripper unit 150 may be fixedly coupled as in FIG. For example, referring to FIG. 6, there is provided a stocker fixing groove 1143b on a horizontal table 143b, and a T-bolt type fastener (not shown) is inserted into the stock fixing fastener groove 1143b So that the welding base material 200 can be directly fixed. At this time, the grooved fixing groove 1143b may be elongated in the center direction so that the gap between the T-bolt type fasteners (not shown) may be adjusted according to the size of the welding base material 200. [ 3, a gripper unit 150 is fixedly coupled to the horizontal table 143b, and the welding base material 200 can be fixed by the gripper unit 150. As shown in FIG.

Further, in one example, the horizontal table unit 143 may further include a gear cover 143c. The gear cover 143c will be described later.

Next, the horizontal rotation motor unit 144 will be described with reference to Figs. 2, 3, 4, 5 and / or 6. The horizontal rotation motor unit 144 is supported by a tilting frame 142. At this time, the horizontal rotation motor unit 144 is gear-engaged with the horizontal table unit 143 and provides the power of the horizontal gear rotation. For example, the horizontal rotation motor unit 144 is installed below the horizontal table 143b. At this time, in one example, the horizontal rotation motor unit 144 is equipped with the pinion gear 144a so as to gear-up with the horizontal rotation gear 143a. That is, the pinion gear 144a is formed at one end of the horizontal rotation motor unit 144, and can be engaged with the edge of the horizontal rotation gear 143a.

For example, referring to FIGS. 2, 3, 5 and / or 6, the turntable unit 140 may further include a center pin 145 having an upper end connected to the center of the horizontal table unit 143 . The center pin 145 forms the center of rotation of the horizontal rotary gear 143a. At this time, the tilting frame 142 may include a center hole and may rotatably accommodate all or a part of the remaining portion except the upper end of the center pin 145. For example, by providing the large center pin 145, the center of gravity of the combined turntable unit 140 and the gripper unit 150 to which the welding base material 200 is not mounted can be moved away from the tilting axis.
