Description

Technical Field

[0001] The utility model relates to the field of welding equipment, and particularly to an automatic welding device. Background Art

[0002] Welding manipulators are widely used in welding operations, suitable for large-scale welding operations, saving time and labor. For some components, the weld seams are formed on the side or are circular weld seams. If the workpiece is fixed on the base and does not move relative to the ground, the manipulator needs to drive the welding torch for multi-angle adjustment, which requires the use of a more complex welding manipulator and makes welding difficult in some parts.

[0003] In view of this, the inventor of the present case has conducted in-depth research on the above-mentioned defects in the prior art, and thus this case has been created. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an automatic welding device, which has the characteristics of simplifying welding processing and adapting to a simple welding manipulator.

[0005] To achieve the above object, the solution of the utility model is:

[0006] An automatic welding device, which includes a welding manipulator and a support base. The support base includes a fixed base, a rotary lower base, a hydraulic cylinder, a rotary mechanism, and a rotary worktable for fixing the workpiece. The fixed base is fixed to the ground. One end of the rotary lower base is rotatably connected to the fixed base. The hydraulic cylinder is arranged on the fixed base to adjust the angular position of the rotary lower base relative to the fixed base. The rotary mechanism is respectively connected to the rotary worktable and the rotary lower base. The rotary worktable can rotate 360 degrees relative to the rotary lower base.

[0007] Further, the rotary mechanism is a servo rotary mechanism.

[0008] Further, the angular range between the two limit positions of the rotary lower base is 110 degrees.

[0009] Further, as the rotary lower base flips, the included angle between the rotary worktable and the horizontal plane ranges from -10 degrees to +100 degrees.

[0010] Further, a plurality of grooves for fixing the workpiece are arranged on the rotary worktable.

[0011] Further, the welding manipulator includes an XYZ three-axis driving mechanism and a welding head that moves along with the XYZ three-axis driving mechanism.

[0012] Further, the rotary worktable is fixedly connected to the rotary mechanism through a plurality of fixing holes evenly distributed in a ring.

[0013] Further, a first oil cylinder base is formed on the rotary lower base, and a second oil cylinder base is formed on the fixed base; the piston head of the hydraulic oil cylinder is rotatably connected to the first oil cylinder base, and the middle part of the cylinder body of the hydraulic oil cylinder is rotatably connected to the second oil cylinder base.

[0014] After adopting the above structure, an automatic welding device according to the present invention has at least the following beneficial effects:

[0015] First, when in use, the workpiece is fixed on the rotary worktable, the hydraulic oil cylinder drives the rotary lower base to adjust the angle, and the rotary mechanism drives the rotary worktable to rotate self - sufficiently, so that the part of the workpiece to be welded is located at a position suitable for welding by the welding manipulator. Therefore, the requirements for the manipulator are reduced, and a simple manipulator can be adapted.

[0016] Second, for a circular weld seam, during the welding process, the welding head can remain stationary, and the circular weld seam is welded by the self - rotation of the rotary worktable. The rotary worktable realizes adjustable - speed rotary work through the servo rotary mechanism.

[0017] Compared with the prior art, by setting the rotary worktable and the rotatable rotary lower base, the present invention enables the workpiece to adjust the angular position relative to the ground, making it easier for the welding manipulator to process the workpiece.

[0027] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0028] As Figures 1 to 7 shown, it is an automatic welding device related to the present invention, including a welding manipulator 1 and a support base 2. The support base 2 includes a fixed base 21, a rotary lower base 22, a hydraulic oil cylinder 23, a rotary mechanism 24 and a rotary table 25 for fixing workpieces. The fixed base 21 is fixed to the ground. One end of the rotary lower base 22 is rotatably connected to the fixed base 21. The hydraulic oil cylinder 23 is arranged on the fixed base 21 to adjust the angular position of the rotary lower base 22 relative to the fixed base 21. The rotary mechanism 24 is respectively connected to the rotary table 25 and the rotary lower base 22. The rotary table 25 can rotate 360 degrees relative to the rotary lower base 22.

[0029] In this way, for an automatic welding device related to the present invention, when in use, the workpiece is fixed on the rotary table 25. The hydraulic oil cylinder 23 drives the rotary lower base 22 to adjust the angle, and the rotary mechanism 24 drives the rotary table 25 to rotate self - rotatably, so that the part of the workpiece to be welded is located at a position suitable for welding by the welding manipulator 1. Therefore, the requirements for the manipulator are reduced, and a simple manipulator can be adapted.

[0030] Preferably, the rotary mechanism 24 is a servo rotary mechanism 24. For a circular weld, during the welding process, the welding head can remain stationary, and the circular weld can be welded by the self - rotation of the rotary table 25. The rotary table 25 realizes adjustable - speed rotary work through the servo rotary mechanism 24.

[0031] Preferably, the angular range between the two extreme positions of the rotary lower base 22 is 110 degrees. As Figure 4 shown, at this time the rotary table 25 is perpendicular to the horizontal plane; as Figure 5 shown, at this time the rotary table 25 is parallel to the horizontal plane; taking the rotary table 25 being flush with the horizontal plane as the reference, as Figure 3 shown, at this time the rotary lower base 22 reaches the positive - angle extreme position, and the angle of the rotary table 25 relative to the reference is + 100 degrees; as Figure 6As shown, at this time, the rotary table 25 reaches the negative angle limit position, and the angle of the rotary table 25 relative to the reference is -10 degrees. That is, as the rotary lower base 22 flips, the included angle between the rotary table 25 and the horizontal plane is between -10 degrees and +100 degrees.

[0032] Preferably, a number of grooves 252 for fixing workpieces are provided on the rotary table 25. The grooves 252 are T-shaped grooves or dovetail grooves.

[0033] Preferably, the welding manipulator 1 includes an XYZ three-axis drive mechanism and a welding head that moves with the XYZ three-axis drive mechanism. Preferably, as Figure 2 shown, the rotary table 25 is fixedly connected to the rotary mechanism 24 through a number of fixing holes 251 evenly distributed in a ring.

[0034] Preferably, as Figure 6 shown, a first oil cylinder base 221 is formed on the rotary lower base 22, and a second oil cylinder base 211 is formed on the fixed base 21; the piston head of the hydraulic oil cylinder 23 is rotatably connected to the first oil cylinder base 221, and the middle part of the cylinder body of the hydraulic oil cylinder 23 is rotatably connected to the second oil cylinder base 211.

[0035] Compared with the prior art, by providing a rotary table 25 and a rotatable rotary lower base 22, the present invention enables the workpiece to adjust the angular position relative to the ground, making it easier for the welding manipulator 1 to process the workpiece.

[0036] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present invention.
