Description

Technical Field

[0001] This application belongs to the technical field of welding equipment, and particularly relates to an automatic welding equipment. Background Art

[0002] There are many disc-shaped welding structures in construction machinery. For example, in a crawler crane, the pull plate plays a role in connecting the turntable, the A-frame, the boom and the counterweight of the crawler crane. When the crawler crane is lifting and hoisting, the pull plate connects and pulls the upper and lower structural members, playing a crucial role in the safe completion of the hoisting of the crane. Generally, reinforcing circular plates in the shape of discs are designed on both sides of the pull plate or the connecting plate, which play a role in strengthening and controlling the opening dimension, and can improve the stress intensity and installation smoothness of the pull plate or the connecting plate.

[0003] At present, the welding operation of welding the reinforcing circular plate on the pull plate is usually carried out manually. Since the weld seam is circular, it is very difficult for manual welding to ensure continuous arc welding in one go. That is, there will be multiple arc breaks when welding the circular plate weld seam, and it is necessary to strike the arc and weld multiple times, resulting in multiple joints of the weld seam and poor consistency, which directly affects the product quality. At the same time, products with poor weld formation need to be frequently reworked, which is laborious and time-consuming; and the labor intensity of workers is high during manual welding, and the work efficiency is relatively low.

It should be understood that the specific implementation manners described herein are only for explaining and interpreting the present application and are not used to limit the present application.

[0049] The present application will be described in detail below with reference to the drawings and in conjunction with exemplary embodiments.

[0050] Embodiment

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 . This embodiment provides an automatic welding device for welding circular welds, especially suitable for welding disc-shaped components in construction machinery.

[0052] In this embodiment, the automatic welding device includes a frame 100, a slewing module 200, a position-changing drive module 400, a welding support module 300, and a welding torch 500. Among them, the frame 100 is placed on the foundation to provide support. The bottom of the frame 100 is provided with a leg seat 600 in contact with the foundation, and the leg seat 600 is used to space the frame 100 from the foundation surface.

[0053] The rotary module 200 includes a rotary drive mechanism 210, a positioning turntable 220 and a clamping mechanism 230. The rotary drive mechanism 210 is rotatably arranged on the frame 100, that is, the rotary drive mechanism 210 can rotate relative to the frame 100 around the axis located in the second direction X. The positioning turntable 220 is arranged on the rotary drive mechanism 210, and the rotary drive mechanism 210 is used to drive the positioning turntable 220 to rotate and displace around the axis located in the first direction Z; a welding area is arranged in the middle of the positioning turntable 220, and the clamping mechanism 230 is arranged on the positioning turntable 220. In this way, before welding, the product is first fixed to the welding area on the positioning turntable 220 by the clamping mechanism 230, and then the rotary drive mechanism 210 drives the positioning turntable 220 to drive the product and the clamping mechanism 230 to rotate around the axis located in the first direction Z.

[0054] In this embodiment, the clamping mechanism 230 can be clamped mechanically by means of a pressure plate and a bolt, or can be clamped by a cylinder clamp.

[0055] The welding support module 300 is arranged on one side of the frame 100. The welding gun 500 is arranged on the welding support module 300, and the welding end of the welding gun 500 faces the welding area. In this way, during the rotation of the positioning turntable 220, the welding gun 500 can form a circular weld in the circumference of the product, thereby realizing automatic welding of the product.

[0056] Further, the displacement drive module 400 is arranged on the frame 100 and is transmission-connected to the rotary module 200. It can be understood that, since the rotary drive mechanism 210 can rotate relative to the frame 100 around the axis located in the second direction X, the displacement drive module 400 can drive the rotary module 200 to rotate and shift relative to the frame 100 around the axis located in the second direction X, so as to adjust the inclination angle of the positioning turntable 220 so that the welding end of the welding gun 500 can be aligned with the weld position on the product, thereby improving the welding quality and accuracy.

[0057] In this embodiment, the first direction Z is perpendicular to the second direction X, wherein the first direction Z is parallel to the normal of the positioning turntable 220 , and the second direction X is located in a horizontal plane.

[0058] Compared with the prior art, the automatic welding equipment provided in this embodiment clamps the product on the positioning turntable 220 through the clamping mechanism 230 in the rotating module 200 during welding, and then drives the rotating module 200 as a whole to adjust the tilt angle through the displacement drive module 400, so that the welding end of the welding gun 500 can be accurately aligned with the weld position. After the proofreading is completed, welding begins, and the positioning turntable 220 and the clamping mechanism 230 on the positioning turntable 220 and the product are driven to rotate together by the rotating drive mechanism 210 in the rotating module 200, and the welding gun 500 performs welding work during the rotation process.

[0059] In this way, the automatic welding equipment provided by this embodiment can automatically complete the welding process without manual intervention, thereby reducing the labor intensity of manual labor, and the welding is completed by the welding gun 500 and the rotary module 200 in coordination, which can ensure the continuity of the weld, greatly reduce the number of welded joints, improve the consistency of the weld, and improve the welding quality. Furthermore, the displacement drive module 400 can adjust the inclination angle of the entire rotary module 200 to meet different welding requirements, further improving the welding quality and welding accuracy.

[0060] In order to more clearly describe the technical solution of the present application, the automatic welding equipment provided in this embodiment is described below. The details are as follows:

[0061] See also Figure 1 and Figure 3 The rotary drive mechanism 210 includes a welding base 211 and a first drive assembly 212. The welding base 211 is rotatably matched with the frame 100, so that the welding base 211 can rotate around an axis located in the second direction X. Specifically, the welding base 211 is provided with a rotating shaft 213 at both ends located in the second direction X, and the frame 100 is provided with a bearing seat 110 that is rotatably matched with the frame 100 on both sides located in the second direction X.

[0062] The first driving assembly 212 is disposed on the welding base 211, wherein the positioning turntable 220 is arranged on the welding base 211 and is in driving connection with the first driving assembly 212. The first driving assembly 212 is used to drive the positioning turntable 220 to rotate around an axis in the first direction Z, specifically to drive the positioning turntable 220 to rotate.

[0063] Optionally, the first drive assembly 212 includes a motor and a transmission, and the motor is connected to the positioning turntable 220 through the transmission. The motor can be a servo motor or a stepper motor. It should be understood that the above is only an example and is not intended to limit the scope of protection of this application.

[0064] In this embodiment, a plurality of universal bearings 214 are further provided on the welding base 211, and the balls of the universal bearings 214 are in rolling contact with the side of the positioning turntable 220 close to the welding base 211. In this way, the universal bearings 214 can provide stable support for the positioning turntable 220 to ensure welding quality, and can also reduce friction between the positioning turntable 220 and the welding base 211.

[0065] Please also read Figure 2 The welding bracket module 300 includes a stand 310, a first cross bar 320 and a second cross bar 330. The stand 310 can be fixedly mounted on one side of the frame 100 through a third fastening assembly 360. The third fastening assembly 360 can be a bolt or a locking clamp.

[0066] The first cross bar 320 is arranged on the first fastening component 340 through the first fastening component 340. The first cross bar 320 is horizontally arranged. The first fastening component 340 is sleeved on the vertical frame 310 and can move up and down along the vertical frame 310 for adjustment. The first fastening component 340 is provided with a mounting hole through which the first cross bar 320 can pass. The first fastening component 340 fixes the first cross bar 320 through fastening bolts to limit the movement of the first cross bar 320.

[0067] The second cross bar 330 is arranged on the first cross bar 320 through the second fastening component 350. The second cross bar 330 is also horizontally arranged, and the arrangement direction of the second cross bar 330 is perpendicular to the arrangement direction of the first cross bar 320. Among them, the second fastening component 350 can also adopt the same structure as the first fastening component 340.

[0068] Of course, in some embodiments, the second fastening component 350 can be fixed on the first cross bar 320. The second fastening component 350 is provided with a mounting hole through which the second cross bar 330 can pass. The second fastening component 350 fixes the second cross bar 330 through fastening bolts to limit the movement of the second cross bar 330.

[0069] The welding torch clamping mechanism 370 is arranged on the second cross bar 330 and clamps the welding torch 500. The welding torch clamping mechanism 370 fixes the welding torch 500 by means of mechanical block clamping and is fastened by screws.

[0070] In some embodiments, the welding torch clamping mechanism 370 is rotationally matched with the second cross bar 330. The rotation axis of the welding torch clamping mechanism 370 is parallel to the length direction of the second cross bar 330. Thus, by rotating the welding torch clamping mechanism 370, the angle of the welding torch 500 can be adjusted so that the welding end of the welding torch 500 can accurately face the position to be welded of the product. Specifically, a threaded shaft is provided on the welding torch clamping mechanism 370, and a threaded hole for inserting the threaded shaft is provided on the end face of the second cross bar 330. A matching locking nut is provided on the threaded shaft.

[0071] Thus, it can be understood that by screwing the locking nut so that the locking nut abuts against the end face of the second cross bar 330, the welding torch clamping mechanism 370 can be locked on the second cross bar 330 to limit the rotation of the welding torch clamping mechanism 370. When the angle of the welding torch 500 needs to be adjusted, first loosen the locking nut, and then it can be rotated for adjustment. After the adjustment is completed, tighten the locking nut again. Of course, in some embodiments, other matching methods can also be used to realize the rotational adjustment of the welding torch clamping mechanism 370. This embodiment is only for illustration and is not a limitation of the protection scope of the present application.

[0072] Please refer to Figure 1 、 Figure 3 andFigure 4 As described above, the position-changing drive module 400 includes a second drive assembly 410 and a transmission mechanism 420. The second drive assembly 410 is disposed on the frame 100. One end of the transmission mechanism 420 is in transmission connection with the rotary drive mechanism 210, and the other end is in transmission connection with the second drive assembly 410. The second drive assembly 410 can output torque, which is transmitted to the rotary drive mechanism 210 through the transmission mechanism 420, thereby driving the rotary mechanism to rotate and change its position.

[0073] Specifically, the transmission mechanism 420 is in transmission connection with the rotating shaft 213 on one side of the welding base 211 in the rotary drive mechanism 210, thereby driving the rotating shaft 213 to rotate, so as to drive the entire rotary module 200 to rotate and change its position.

[0074] Furthermore, the second drive assembly 410 includes a drive member 411 and a transmission shaft 412. The drive member 411 is in transmission connection with the transmission mechanism 420 through the transmission shaft 412.

[0075] Optionally, the transmission mechanism 420 is a sprocket drive mechanism, a pulley drive mechanism, a gear drive mechanism or a worm and worm gear drive mechanism. It should be understood that the above are only examples and do not limit the protection scope of the present application.

[0076] Optionally, the drive member 411 is a handwheel (as shown in Figure 3 ) or a motor. Among them, the handwheel can be manually controlled. The motor realizes automatic control.

[0077] In this embodiment, the automatic welding equipment further includes an electric control box 700, and the electric control box 700 is arranged on the frame 100. Among them, a controller is built in the electric control box 700, such as a PLC controller or a single-chip microcomputer, etc. Function keys 710 are provided on the electric control box 700.

[0078] Please refer to Figure 3 and Figure 4 . It can be understood that the entire welding process is controlled and operated by the electric control box 700. The electric control box 700 functions to convert energy signals, control signal output and input, etc., and controls the entire mechanism device to safely complete various operations and data processing, etc.; among them, the pause button in the function keys is used to pause the work during the welding process to ensure the safe operation during workpiece welding; the rotation adjustment button 32 in the function keys is used to control the rotation direction of the positioning turntable 220 during welding. By adjusting the rotation adjustment button, the positioning turntable 220 can be rotated clockwise or counterclockwise, ensuring the diversity of welding directions.

That is, there is no need to use equal-height pads or adopt other methods to level the workpieces, realizing the welding of circular plate workpieces with different structural forms. At the same time, the clamping mechanism 230 is added to fix the workpiece, facilitating the free flipping of the workpiece and ensuring that the product to be welded does not fall off or change its position when the positioning turntable 220 flips and tilts.

[0081] 2. In the welding support module 300 of the automatic welding equipment, through the cooperation of the first fastening component 340, the second fastening component 350 and the welding torch clamping mechanism 370, multi-directional adjustment of the welding torch 500 can be realized, ensuring that the welding torch 500 is arranged in a suitable spatial position; and it can change accordingly according to the spatial position of the product, increasing the structural diversity of the weldable products.
