Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a welding device for laser and argon arc welding. Background Art

[0002] The laser and argon arc welding device is a composite welding device that combines laser welding and argon arc welding. This device is usually used in applications that require high-precision and high-quality welding.

[0003] When adjusting the angle of each welding head with the existing welding device, it is necessary to first loosen the bolts to release the universal ball head between the two pressure plates, and then manually rotate the ball head to adjust the position of the welding head. After the position is adjusted, it is necessary to maintain the position with one hand and tighten the bolt with the other hand. This adjustment procedure is relatively cumbersome, resulting in low adjustment efficiency. The adjustment position still has limitations. When dealing with complex shapes of workpieces, the problem of the welding head touching the workpiece still occurs. Summary of the invention

When adjusting, it is only necessary to rotate the corresponding parts, which simplifies the adjustment steps and improves the adjustment efficiency. The multi-dimensional adjustment method avoids the problem of the welding head touching the workpiece due to the complex shape of the workpiece, and the angle and position of the welding head can be adjusted at any time to meet different welding requirements.

When adjusting, only the corresponding parts need to be rotated, which simplifies the adjustment steps and improves the adjustment efficiency. The multi-dimensional adjustment method avoids the problem of the welding head touching the workpiece due to the complex shape of the workpiece, and the angle and position of the welding head can be adjusted at any time to meet different welding requirements.

[0006] The adjusting mechanism includes arc-shaped worm gear plates respectively arranged on the outer ends of the rotating plate and the adjusting cylinder. A worm is rotatably connected to the adjusting cylinder and the connecting seat near each arc-shaped worm gear plate. The worm is respectively meshed and connected with the adjacent arc-shaped worm gear plates on the same side, thereby realizing the adjustment of the inclination angle of the argon arc welding head and the wire feeding head.

[0007] A screw rod is rotatably connected in the adjusting cylinder, and the screw rod is threadedly connected to the corresponding screw holes on the adjacent rotating plates on the same side, so as to adjust the overall length of the rotating plate and the adjusting cylinder.

[0008] The lower ends of the adjusting cylinders are rotatably connected with driving plates, and the driving plates are respectively fixedly connected to the outside of the screw rods located on the same adjusting cylinder, so as to play a role of rapid driving.

[0009] The adjustment assembly includes a sliding sleeve slidably connected to the outside of the laser welding head, a rotating ring is rotatably connected to the step surface of the fixed ring, a plurality of fixed cylinders are provided on the rotating ring, and a plurality of connecting cylinders are provided on the top wall surface of the sliding sleeve.

[0010] The adjustment component also includes a crown gear ring 1 arranged on the step surface at the lower end of the outer end of the sliding sleeve, and a crown gear ring 2 is provided at the upper end of the rotating ring. The crown gear ring 2 is arranged in cooperation with the crown gear ring 1 to ensure that the rotating ring and its auxiliary mechanisms are stably maintained in the adjusted position.

[0011] It also includes a locking assembly, which is used to lock the argon arc welding head and the wire feeding head. The locking assembly includes arc-shaped top plates respectively slidably connected to the fixing sleeves, and the screw holes arranged outside the fixing sleeves are threadedly connected with locking bolts. The inner ends of the locking bolts are respectively rotatably connected to the arc-shaped top plates located in the same fixing sleeve, thereby achieving the fixation of the argon arc welding head and the wire feeding head.

[0014] The beneficial effects of the above technical solution of the present invention are as follows:

[0015] 1. When it is necessary to adjust the inclination angle of the argon arc welding head and the wire feeding head according to the shape of the workpiece, rotate the corresponding worm. When the worm on the fixed seat is rotated, the arc-shaped worm gear plate meshing with it drives the rotating plate and its auxiliary mechanism to adjust the angle. When the worm on the connecting seat is rotated, the arc-shaped worm gear plate meshing with it drives the connecting seat and its auxiliary mechanism to rotate, thereby realizing the adjustment of the inclination angle of the argon arc welding head and the wire feeding head. When it is necessary to adjust the overall length of the rotating plate and the adjusting cylinder, rotate the driving plate in turn. When the driving plate rotates, it drives the corresponding lead screw to rotate synchronously, so that the rotating plate and the adjusting cylinder slide relative to each other, so as to adjust the overall length of the rotating plate and the adjusting cylinder. When adjusting, you only need to rotate the corresponding parts, which simplifies the adjustment steps and improves the adjustment efficiency.

[0016] 2. When it is necessary to adjust the circumferential angle of the argon arc welding head and the wire feeding head, lift the sliding sleeve, and the sliding sleeve, connecting tube and crown gear ring 1 overcome the elastic force of the spring and move up along the laser welding head. After the crown gear ring 1 is separated from the crown gear ring 2, rotate the rotating ring and its accessories to rotate synchronously to adjust the circumferential angle of the argon arc welding head and the wire feeding head. The multi-dimensional adjustment method avoids the problem of the welding head touching the workpiece due to the complex shape of the workpiece, and the angle and position of the welding head can be adjusted at any time to meet different welding requirements.

[0017] 3. When it is necessary to fix the argon arc welding head and the wire feeding head, just tighten the corresponding locking bolt. The rotation of the locking bolt drives the arc top plate to move toward the argon arc welding head and the wire feeding head, and cooperates with the fixing sleeve to fix the argon arc welding head and the wire feeding head. When locking the optical fiber head, first insert the optical fiber head into the locking seat. During this process, the locking pin and the adjacent anti-retraction guide pin will slide with the locking groove in turn. After the optical fiber head is fully embedded, rotate the locking ring to make the locking pin slide into the locking groove. The locking ring is then tightened to press the locking ring downward, and the boss on the step surface at the upper end of the locking ring cooperates with the groove on the locking ring to limit the position of the locking ring and apply a downward pressure on the locking ring and the locking pin, so that the locking pin presses the horizontal section of the locking groove to increase the downward pressure, thereby ensuring that the optical fiber head is firmly locked and reducing the number of parts. It only takes two steps to connect and fix, and when the optical fiber head needs to be removed, only the reverse operation is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] When it is necessary to adjust the inclination angle of the argon arc welding head 109 and the wire feeding head 110 according to the shape of the workpiece, the rotating plate 105 and its accessories are driven to adjust the angle or the connecting seat 107 and its accessories are driven to rotate, so as to adjust the inclination angle of the argon arc welding head 109 and the wire feeding head 110. When it is necessary to adjust the overall length of the rotating plate 105 and the adjusting cylinder 106, the adjusting cylinder 106 is driven to slide along the rotating plate 105, so as to adjust the overall length of the adjusting cylinder 106 along the rotating plate 105. When adjusting, only the corresponding parts need to be rotated, which simplifies the adjustment steps and improves the adjustment efficiency. When it is necessary to adjust the circumferential angle of the argon arc welding head 109 and the wire feeding head 110, the rotating ring 103 and its accessories are rotated synchronously, so as to adjust the circumferential angle of the argon arc welding head 109 and the wire feeding head 110. The multi-dimensional adjustment method avoids the problem of the welding head touching the workpiece due to the complex shape of the workpiece, and the angle and position of the welding head can be adjusted at any time to meet different welding needs.

[0029] When it is necessary to adjust the inclination angle of the argon arc welding head 109 and the wire feeding head 110 according to the shape of the workpiece, the corresponding worm 201 is rotated. When the worm 201 on the fixed seat 104 is rotated, the arc worm gear plate 200 meshing with it drives the rotating plate 105 and its ancillary mechanisms to adjust the angle. When the worm 201 on the connecting seat 107 is rotated, the arc worm gear plate 200 meshing with it drives the connecting seat 107 and its ancillary mechanisms to rotate, thereby realizing the adjustment of the inclination angle of the argon arc welding head 109 and the wire feeding head 110.

The screw rod 202 is threadedly connected to the corresponding screw holes on the adjacent rotating plates 105 on the same side, and the screw rod 202 rotates synchronously, so that the rotating plate 105 and the adjusting cylinder 106 slide relative to each other, so as to adjust the overall length of the rotating plate 105 and the adjusting cylinder 106. When adjusting, only the corresponding parts need to be rotated, which simplifies the adjustment steps and improves the adjustment efficiency.

The driving plates 203 are respectively fixedly connected to the outside of the screw rod 202 located on the same adjusting cylinder 106. When it is necessary to adjust the overall length of the rotating plate 105 and the adjusting cylinder 106, the driving plates 203 are rotated in turn. When the driving plate 203 rotates, it drives the corresponding screw rod 202 to rotate synchronously, thereby playing a role of rapid driving.

[0033] When it is necessary to adjust the circumferential angle of the argon arc welding head 109 and the wire feeding head 110, lift the sliding sleeve 300, the sliding sleeve 300, the connecting tube 303 and the crown gear ring 1 305 overcome the elastic force of the spring 304 and move up along the laser welding head 100. After the crown gear ring 1 305 is separated from the crown gear ring 2 306, rotate the rotating ring 103 and its accessories to rotate synchronously, so as to adjust the circumferential angle of the argon arc welding head 109 and the wire feeding head 110. The multi-dimensional adjustment method avoids the problem of the welding head touching the workpiece due to the complex shape of the workpiece, and the angle and position of the welding head can be adjusted at any time to meet different welding requirements.

[0034] like Figure 1-4 As shown, the adjustment component also includes a crown gear ring 1 305 arranged on the stepped surface at the lower end of the outer portion of the sliding sleeve 300, and a crown gear ring 2 306 is provided at the upper end of the rotating ring 103. The crown gear ring 2 306 is arranged in coordination with the crown gear ring 1 305. When the crown gear ring 2 306 is engaged with the crown gear ring 1 305, the rotating ring 103 and its auxiliary mechanisms are limited and fixed to ensure that the rotating ring 103 and its auxiliary mechanisms are stably maintained in the adjusted position.

[0035] like Figure 1-3 As shown, it also includes a locking assembly, which is used to lock the argon arc welding head 109 and the wire feeding head 110.

[0036] When it is necessary to fix the argon arc welding head 109 and the wire feeding head 110, it is only necessary to tighten the corresponding locking bolt 401. The locking bolt 401 rotates to drive the arc top plate 400 to move toward the argon arc welding head 109 and the wire feeding head 110, and cooperates with the fixing sleeve 108 to fix the argon arc welding head 109 and the wire feeding head 110.

[0037] like Figure 1-5As shown, the locking assembly includes a locking seat 500 disposed at the upper end of the laser welding head 100, the upper end of the locking seat 500 is provided with a plurality of grooves, the outer movable sleeve of the locking seat 500 is provided with a locking ring 501, the upper step surface of the locking ring 501 is provided with bosses corresponding to the grooves one by one, the lower end of the inner arc surface of the locking ring 501 is provided with a plurality of locking pins 502, the outer arc surface of the locking seat 500 is provided with waist holes 503 corresponding to each locking pin 502, and the locking pins 502 are respectively passed through the same The adjacent waist hole 503 on the side extends into the locking seat 500, the outer arc surface of the optical fiber head 101 is provided with a locking groove 504 adapted to each locking pin 502, the movable sleeve in the locking ring 501 is provided with a stop ring 505, the locking seat 500 is provided with a stop guide pin 506 at the upper end near the locking pin 502, the lower end of the locking ring 501 is provided with an avoidance groove 507 adapted to the stop guide pin 506, and the stop guide pin 506 is matched with the locking groove 504 adjacent to the same side.

[0038] The optical fiber head 101 is first inserted into the locking seat 500. During this process, the locking pin 502 and the adjacent anti-retraction guide pin 506 will slide and cooperate with the locking groove 504 in turn. After the optical fiber head 101 is fully engaged, the locking ring 501 is rotated to make the locking pin 502 slide into the horizontal section of the locking groove 504, and then the anti-retraction ring 505 is pressed down, and the boss on the step surface at the upper end of the anti-retraction ring 505 will cooperate with the groove on the locking ring 501, thereby limiting the position of the locking ring 501 and applying a downward pressure on the locking ring 501 and the locking pin 502, so that the locking pin 502 presses the horizontal section of the locking groove 504, making the downward pressure greater, thereby ensuring that the optical fiber head 101 is firmly locked, reducing the number of parts, and only two steps are required to connect and fix. When the optical fiber head 101 needs to be removed, only the reverse operation is required.

[0040] The working principle of a laser and argon arc welding device provided by the present invention is as follows: when it is necessary to adjust the inclination angle of the argon arc welding head 109 and the wire feeding head 110 according to the shape of the workpiece, the corresponding worm 201 is rotated, and when the worm 201 on the fixed seat 104 is rotated, the arc worm gear plate 200 meshing with it drives the rotating plate 105 and its auxiliary mechanism to adjust the angle, and when the worm 201 on the connecting seat 107 is rotated, the arc worm gear plate 200 meshing with it drives the connecting seat 107 and its auxiliary mechanism to rotate, thereby realizing the adjustment of the inclination angle of the argon arc welding head 109 and the wire feeding head 110, when it is necessary to adjust the overall length of the rotating plate 105 and the adjusting cylinder 106, the driving plate 203 is rotated in turn, When the driving plate 203 rotates, the corresponding screw rod 202 is driven to rotate synchronously, so that the rotating plate 105 and the adjusting cylinder 106 slide relative to each other, so as to adjust the overall length of the rotating plate 105 and the adjusting cylinder 106. When adjusting, it is only necessary to rotate the corresponding parts, which simplifies the adjustment steps and improves the adjustment efficiency. When it is necessary to adjust the circumferential angle of the argon arc welding head 109 and the wire feeding head 110, lift the sliding sleeve 300, the sliding sleeve 300, the connecting cylinder 303 and the crown gear ring 1 305 overcome the elastic force of the spring 304 and move up along the laser welding head 100. After the crown gear ring 1 305 is separated from the crown gear ring 2 306, the rotating ring 103 and its accessories are rotated synchronously to adjust the circumferential angle of the argon arc welding head 109 and the wire feeding head 110. The dimensional adjustment method avoids the problem of the welding head touching the workpiece due to the complex shape of the workpiece, and the angle and position of the welding head can be adjusted at any time to adapt to different welding requirements. When the argon arc welding head 109 and the wire feeding head 110 need to be fixed, it is only necessary to tighten the corresponding locking bolt 401. The locking bolt 401 rotates to drive the arc top plate 400 to move toward the argon arc welding head 109 and the wire feeding head 110, and cooperates with the fixing sleeve 108 to fix the argon arc welding head 109 and the wire feeding head 110. When locking the optical fiber head 101, first insert the optical fiber head 101 into the locking seat 500. During this process, the locking pin 502 and the adjacent anti-retraction guide pin 506 will slide and cooperate with the locking groove 504 in turn. After the optical fiber head 101 is fully engaged, the locking ring 501 is rotated so that the locking pin 502 slides into the horizontal section of the locking groove 504, and then the clamping screw ring 508 is tightened so that the clamping screw ring 508 presses down the retaining ring 505, and the boss on the step surface at the upper end of the retaining ring 505 cooperates with the groove on the locking ring 501, thereby limiting the position of the locking ring 501 and applying a downward pressure on the locking ring 501 and the locking pin 502, so that the locking pin 502 presses the horizontal section of the locking groove 504, making the downward pressure greater, thereby ensuring that the optical fiber head 101 is firmly locked, reducing the number of parts, and only two steps are required to connect and fix. When the optical fiber head 101 needs to be removed, only the reverse operation is required.

[0041] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
