Description

TECHNICAL FIELD

[0002] With the increase of product types and the continuous improvement of product quality requirements, people's requirements for welding process are also increasing. Many products originally welded by manual work have gradually developed towards automation. In order to reduce labor costs and greatly improve production efficiency, most of the work of the existing welding production line can be completed by the cooperation of welding robots and positioners. However, problems still occur during the welding process of the welding robot, as follows:

[0003] 1. When the welding robot is executing a task, if the welding parameters are not properly set, such as too low current resulting in insufficient welding pool temperature, the molten metal cannot be completely distributed, thereby producing less slag, or the moving speed is too fast, which may cause the welding pool to be unable to fill up in time, the molten metal cannot completely solidify or cool down too early, affecting the generation of slag.

[0004] 2. When the wire tension is too loose, the welding wire may not be stably fed to the welding area, which may cause uneven wire feeding, burning, unstable welding pool and other problems, which may result in uneven quality of the weld, and may form pores, cracks and other defects. In addition, uneven wire tension may cause unstable load of the wire feeding motor, causing instability or failure of the robot operation system, and affecting the overall welding operation performance.

[0047] When the first motor 237 is started, the first rotating rod 236 is rotated, the fixed disc 235 is fixed in the inner side of the fixed tube 21, the rotating shaft 233 is rotated around the first rotating rod 236 through the rotation of the fixed disc 235, so that the moving hammer 22 is moved in the inner side of the fixed tube 21 through the moving rod 23 during the rotation of the rotating shaft 233, the compression ring 221 fixed on the side of the moving hammer 22 is clamped in the middle of the elastic spring 213, the elasticity of the elastic spring 213 is changed through the dragging of the moving shaft 222 to the moving hammer 22, the effect of the compression ring 221 acting on the moving hammer 22 is more obvious, the beating of the welding part is more rhythmic, but the beating force on the welding part is not so strong.

[0048] Reference Figures 6 to 10The side of the U-shaped plate 31 is provided with a fixed slide groove 311, the inner side of the fixed slide groove 311 is connected to the side of the U-shaped slide plate 33, the inner side of the U-shaped plate 31 is provided with a T-shaped slide groove 312, the inner side of the rotating disk 313 is provided with a rotating groove 314, the side of the connecting rod 343 is fixedly connected with a driving disk 34, the side of the driving disk 34 is fixedly connected with a second rotating rod 341, the top end of the second rotating rod 341 is fixedly connected with a third motor 342, and the bottom end of the third motor 342 is fixedly connected to the side of the mounting groove 103.

[0049] Among them, the top of the U-shaped slide plate 33 is fixedly connected to a pressure plate 331, the top of the pressure plate 331 is fixedly connected to a T-shaped guide rod 332, the top of the pressure plate 331 is fixedly connected to a compression spring 333, the side of the T-shaped guide rod 332 is connected to the inner side of the compression spring 333, and the top of the compression spring 333 is fixedly connected to a load-bearing plate 323.

[0050] Among them, a T-shaped sliding plate 324 is fixedly connected to the side of the load-bearing plate 323, the side of the T-shaped sliding plate 324 is connected to the inner side of the T-shaped sliding groove 312, the side of the load-bearing plate 323 is connected to the side of the T-shaped guide rod 332, an I-shaped auxiliary rod 32 is connected to the side of the load-bearing plate 323, the side of the I-shaped auxiliary rod 32 is connected to the inner side of the U-shaped plate 31, a second motor 322 is fixedly connected to the top of the U-shaped plate 31, a screw rod 321 is fixedly connected to the bottom of the second motor 322, and the side of the screw rod 321 is threadedly connected to the inner side of the load-bearing plate 323.

[0051] The tightening mechanism 4 includes a first fixing bolt 41 and a connecting plate 42. The connecting plate 42 has a fixing groove 422 on its side. The side of the first fixing bolt 41 is connected to the inside of the fixing groove 422. The inside of the fixing groove 422 is connected to the side of the second fixing bolt 411. A Z-shaped fixing rod 412 is fixedly connected to the side of the first fixing bolt 41. A fixing tooth 421 is fixedly connected to the side of the connecting plate 42. The side of the fixing tooth 421 is connected to the bottom end of the U-shaped sliding plate 33. The side of the first fixing bolt 41 is connected to the inside of the mounting groove 103.

[0052] The movement of the driving mechanism 3 is realized through the effect between the welding wire 5 and the guide pipe 105, and the welding wire 5 is attached to the inner side of the guide pipe 105, which means that the welding wire 5 is loose on the inner side of the guide pipe 105, and the tension of the welding wire 5 will affect the welding process of the bottom end of the rotating rod 108, so that the tension of the welding wire 5 is at the same level, when the contact between the two is started, the third motor 342 is started, the third motor 342 drives the U-shaped plate 31 to rotate around the center point of the rotating disc 313, and at the same time, the second motor 322 at the top end of the U-shaped plate 31 is also started to compress the U-shaped slide plate 33 on the side of the fixed tooth 421, and the welding wire 5 wound on the side of the first fixed bolt 41 is tightened in the opposite direction, so that the tension reaches the required vertical state, and the rotation of the third motor 342 is stopped, and the second motor 322 needs to move the bearing plate 323 to the top end of the T-shaped sliding groove 312, so that the U-shaped slide plate 33 is away from the fixed tooth 421, and the release rotation of the welding wire 5 is continued.

[0053] The compression spring 333 is fixed between the bearing plate 323 and the pressing plate 331, when the bearing plate 323 is at the top end of the T-shaped sliding groove 312, the top end of the T-shaped guide rod 332 drives the pressing plate 331 to move upward, so that the bottom end of the U-shaped slide plate 33 is not in contact with the top end of the fixed tooth 421, at this time, the compression spring 333 is in a non-acting state, and the original length of the compression spring 333 is the length of the T-shaped guide rod 332, the bearing plate 323 is moved by the screw action of the screw rod 321, and since the other end of the bearing plate 323 is connected with the work-type auxiliary rod 32, the rotating force of the screw rod 321 is converted into the action force of the up-down movement by the work-type auxiliary rod 32; when the bearing plate 323 is at the bottom end of the T-shaped sliding groove 312, the bottom end of the U-shaped slide plate 33 is connected with the side of the fixed tooth 421, at this time, the compression spring 333 is in a compressed state, and the U-shaped slide plate 33 is pressed on the side of the fixed tooth 421 by the force applied by the compression spring 333 to the pressing plate 331, but when the U-shaped slide plate 33 rotates with the rotation of the U-shaped plate 31, the U-shaped slide plate 33 will move between different fixed teeth 421, and the connecting disc 42 is reversely rotated by the action force between the U-shaped slide plate 33 and the fixed tooth 421 to tighten the welding wire 5.

[0054] The working principle of the present application is that the welding wire 5 at the bottom end of the rotating rod 108 is moved to the corresponding position for welding through the cooperation of the installation groove 103 and the cross rod 104, the welding wire 5 required is installed on the inner side of the installation groove 103, is taken out through the guide pipe 105, is turned through the steering wheel 107, and is taken out from the rotating rod 108, since the welding process needs to consume the welding wire 5, the welding wire 5 is uniformly sent to the bottom end of the rotating rod 108 in the support mechanism 1.

[0055] The top end of the connecting plate 109 fixedly connected to the side of the rotating rod 108 is provided with the slag removing mechanism 2. When the welding is performed at the bottom end of the rotating rod 108, the other end of the connecting plate 109 is connected to the moving hammer 22 which can clean the slag at the welded place. The first rotating rod 236 is driven to rotate by starting the first motor 237, the rotating shaft 233 at the top end of the first rotating rod 236 is rotated, the other end of the rotating shaft 233 is clamped to the inner side of the rotating slot 231 through the rotating clamping slot 234, the two can rotate relative to each other, the bottom end of the moving rod 23 is connected to the fixed lug 223 through the work-shaped rod 232, so that the fixed lug 223 moves with the moving rod 23 during the rotation of the first rotating rod 236. Since the side of the moving hammer 22 is limited by the side of the elastic spring 213, the movement of the moving hammer 22 is in the vertical direction, and the compression ring 221 fixed to the side of the moving hammer 22 is limited by the elastic spring 213, so that the compression ring 221 can only move in the inner side of the fixed baffle 211, and the side of the compression ring 221 is fixed in the middle of the elastic spring 213, and the movement of the moving hammer 22 is enhanced by the elastic spring 213.

[0056] When the welding wire 5 is excessively elongated in the inner side of the guide pipe 105, the welding wire 5 needs to be tightened, so that the welding material at the bottom end of the rotating rod 108 is more uniform. Therefore, the third motor 342 can be started after the welding wire 5 is contacted to the inner side of the guide pipe 105, the connecting rod 343 at the edge of the disc 34 is connected to the rotating disc 313 and drives the rotating disc 313 to rotate. In the normal operation process, the U-shaped plate 31 is in the horizontal position and does not interfere with the rotation of the first fixed bolt 41. When the U-shaped plate 31 rotates, the second motor 322 is started, the bearing plate 323 is moved from the top end of the T-shaped sliding slot 312 to the bottom end of the T-shaped sliding slot 312, and the compression spring 333 at the top end of the pressing plate 331 is in the compressed state. Therefore, the elastic potential energy gathered in the inner side of the compression spring 333 acts between the pressing plate 331 and the bearing plate 323, so that the bottom end of the U-shaped sliding plate 33 is clamped in the gap of the fixed tooth 421, and the welding wire 5 is released.

[0057] When the third motor 342 drives the rotating disc 313 to rotate, the first fixed bolt 41 rotates in the opposite direction, the welding wire 5 is tightened, the power supply of the third motor 342 is disconnected when the welding wire 5 is not contacted to the inner side of the guide pipe 105, the U-shaped plate 31 is stopped, and the bearing plate 323 is moved to the top end of the T-shaped sliding slot 312, so that the bottom end of the U-shaped sliding plate 33 is moved away from the side of the fixed tooth 421, and the first fixed bolt 41 and the second fixed bolt 411 continue to rotate, and the welding wire 5 on the side of the first fixed bolt 41 and the second fixed bolt 411 continues to be uniformly welded.

[0058] The above merely describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
