[0041] As Figure 1 shown, the present invention provides a welding torch positioning device, which includes a main body mechanism 1, a connecting mechanism 2, a support frame 3, a swing frame 4, a first positioning member 5 and a second positioning member 6. Among them, the connecting mechanism 2 is installed on the main body mechanism 1, and the main body mechanism 1 can drive the connecting mechanism 2 to move in a first direction. The support frame 3 is installed on the connecting mechanism 2, and the connecting mechanism 2 can drive the support frame 3 to move in a second direction, where the second direction is perpendicular to the first direction. The swing frame 4 is rotatably connected to the support frame 3 for installing the welding torch 100, and the swing frame 4 can drive the welding torch 100 to swing in a third direction, where the third direction is perpendicular to the first direction and the second direction. The first positioning member 5 is connected to the swing frame 4 and can be engaged with the longitudinal bars 201 of the mesh reinforcement in the first direction, so that the welding torch 100 is aligned with the set longitudinal bars 201. The second positioning member 6 is connected to the support frame 3 and can abut against the transverse bars 202 of the mesh reinforcement in the second direction, so that the welding torch 100 is aligned with the set transverse bars 202.

[0042] In the present invention, the welding torch positioning device can finely position the welding torch 100 when the welding torch 100 welds the mesh reinforcement, avoid the error deviation of the welding points, press down on the mesh reinforcement through the connecting mechanism 2 to achieve positioning in the first direction, drive the swing frame 4 to swing through the engagement of the first positioning member 5 and the longitudinal bars 201 during pressing down to achieve positioning in the third direction, and when the support frame 3 moves in the second direction, achieve positioning in the second direction through the abutment of the second positioning member 6 and the transverse bars 202. The overall positioning has high accuracy, good stability, high efficiency, and is simple and convenient to operate, so that when the welding torch 100 moves continuously, it can continuously maintain precise positioning with the welding points.

[0043] When the welding torch positioning device of the present invention is specifically used, it is used in conjunction with a welding manipulator to correct small-range deviations on the basis of the welding manipulator, so that the welding manipulator can work continuously and efficiently, meet the welding requirements of large-scale mesh steel bars, reduce repeated positioning during welding, and eliminate the need for wire binding connection in lap welding of steel bars.

[0044] Optionally, the main body mechanism 1 includes a main body frame 11 and a first driver 12. Among them, the connecting mechanism 2 is slidably arranged on the main body frame 11 in the first direction, and the first driver 12 is installed on the main body frame 11 and can drive the connecting mechanism 2 to slide relative to the main body frame 11. The above settings make the movement of the connecting mechanism 2 on the main body mechanism 1 more stable and reliable.

[0045] In this embodiment, the main body frame 11 is fixedly connected to the welding manipulator during use, and is provided with two first guide rails extending in the first direction. The connecting mechanism 2 is slidably arranged on the two first guide rails. The first driver 12 is a cylinder, and the cylinder body of the cylinder is fixed on the main body frame 11, located between the two first guide rails, and the piston rod of the cylinder is connected to the connecting mechanism 2.

[0046] Specifically, the connecting mechanism 2 includes a connecting frame 21 and a second driver 22. Among them, the connecting frame 21 is installed on the main body mechanism 1, and the main body mechanism 1 can drive the connecting frame 21 to move in the first direction. The support frame 3 is slidably arranged on the connecting frame 21 in the second direction, and the second driver 22 is installed on the connecting frame 21 and can drive the support frame 3 to slide relative to the connecting frame 21. The above settings make the movement of the support frame 3 on the connecting mechanism 2 more stable and reliable.

[0047] In this embodiment, the connecting frame 21 is slidably arranged on the two first guide rails, the output end of the first driver 12 is connected to the connecting frame 21, the connecting frame 21 is provided with a second guide rail extending in the second direction, the support frame 3 is slidably arranged on the second guide rail, and the second driver 22 is also a cylinder. The cylinder body of the cylinder is fixed on the connecting frame 21, and the piston rod of the cylinder is connected to the support frame 3.

[0048] More specifically, a first elastic member 31 is arranged on the support frame 3. Two ends of the first elastic member 31 are respectively connected to the support frame 3 and the swing frame 4, so that the support frame 3 and the swing frame 4 maintain a certain initial angle in the free state.

[0049] In this embodiment, the first elastic member 31 is a spring. Taking the rotation axis of the swing frame 4 as the boundary, the spring is located on the side away from the first positioning member 5, and the two ends are respectively connected to the support frame 3 and the swing frame 4. In the free state, the first positioning member 5 is kept in a state parallel to the first direction.

[0050] Optionally, the first positioning member 5 includes a second elastic member 51, a support plate 52, and two clamping posts 53. The two ends of the second elastic member 51 are respectively connected to the swing frame 4 and the support plate 52. The two clamping posts 53 are arranged at an angle and are respectively connected to the support plate 52. The longitudinal bars 201 of the mesh reinforcement can be clamped between the two clamping posts 53. With the above arrangement, the first positioning member 5 can clamp the longitudinal bars 201 of the mesh reinforcement through the two clamping posts 53 to align the welding torch 100 with the set longitudinal bars 201, which is simple to operate, safe and reliable.

[0051] Specifically, the first positioning member 5 further includes two rollers 54. A roller 54 is rotatably sleeved on each clamping post 53. With the above arrangement, after the positioning of the welding torch 100 in the first direction and the third direction is completed, when the support frame 3 moves along the second direction, the two clamping posts 53 clamped to the longitudinal bars 201 can smoothly slide along the longitudinal bars 201 through the two rollers 54.

[0052] More specifically, the first positioning member 5 further includes a guide rod 55. A guide hole is provided on the swing frame 4, and the guide rod 55 is inserted through the guide hole and is connected to the support plate 52 at one end. With the above arrangement, the swing of the support plate 52 and the two clamping posts 53 is more stable and reliable.

[0053] In this embodiment, the second elastic member 51 is a compression spring, which is sleeved outside the guide rod 55. With the assistance of the guide rod 55, the deformation of the compression spring is safer and more reliable.

[0054] Optionally, the second positioning member 6 includes a support plate 61 and a positioning claw 62 connected to the support plate 61. The support plate 61 is connected to the support frame 3, and the positioning claw 62 can abut against the transverse bars 202 of the mesh reinforcement along the second direction. With the above arrangement of the specific structure of the second positioning member 6, it is safe and reliable when abutting against the transverse bars 202.

[0055] Specifically, two positioning claws 62 are provided. The two positioning claws 62 are parallel to each other and arranged at intervals. The arrangement of the two positioning claws 62 makes the abutting and positioning against the transverse bars 202 more accurate and reliable.

[0056] More specifically, a positioning port is provided on the support plate 61. The gun head of the welding torch 100 passes through the positioning port and extends between the two positioning claws 62. With the above arrangement, the positioning of the welding torch 100 by the second positioning member 6 is more accurate, and the two positioning claws 62 can also isolate and protect the gun head of the welding torch 100.

[0057] When the welding torch positioning device of the present invention is specifically used:

[0058] First, the welding torch positioning device is cooperatively installed on the welding torch 100 of the welding manipulator. The welding manipulator is a conventional device in the art, and its specific structure and working principle will not be elaborated here.

[0059] Then, the welding manipulator drives the welding torch 100 to move to the lap joint of the set longitudinal bars 201 and the set transverse bars 202 to be welded. For large mesh steel bars, since there are many welding points to be welded, during continuous operation, the position where the welding manipulator drives the welding torch 100 to move may have a certain deviation from the lap joint of the set longitudinal bars 201 and the set transverse bars 202 to be welded.

[0060] At this time, the first driver 12 drives the connecting frame 21 to move downward until it abuts on the transverse bar 202 of the mesh steel bar, completing the positioning in the first direction, that is, the vertical direction.

[0061] During the process of the first driver 12 driving the connecting frame 21 to move downward, the two clamping columns 53 arranged at an angle on the first positioning member 5 straddle the set longitudinal bar 201, driving the swing frame 4 to slightly swing relative to the support frame 3, completing the positioning in the third direction, that is, the horizontal transverse direction.

[0062] Then, the second driver 22 drives the support frame 3 to slide horizontally until the two positioning claws 62 of the second positioning member 6 abut on the set transverse bar 202, completing the positioning in the second direction, that is, the horizontal longitudinal direction.

[0063] After the positioning is completed, the tip of the welding torch 100 is aligned with the lap joint of the set longitudinal bar 201 and the set transverse bar 202, and the lap joint is welded.

[0064] After the welding is completed, the second driver 22 drives the support frame 3 to reset, the first driver 12 drives the connecting frame 21 to reset, and the welding manipulator drives the welding torch 100 to move to the next welding point, repeating the above actions.

[0065] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
