Description

Technical Field

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

[0002] Laser plasma hybrid welding technology is an advanced welding method that combines the high energy density of laser welding and the good heat source characteristics of plasma arc welding. This technology uses the interaction between the plasma generated by the laser and the plasma arc to effectively reduce the laser reflectivity and improve the stability of the welding process and the welding quality.

[0003] Existing laser and plasma hybrid welding devices usually adopt common workpiece clamping methods during operation, such as using chucks and other fixture structures. Although these fixtures can fix the workpiece, they have certain limitations when cooperating with laser heads and plasma heads to perform welding operations on workpieces with complex shapes. Even if the laser head and plasma head can be adjusted in position, since the position of the workpiece itself remains relatively unchanged, this often leads to a limited welding area, which in turn causes problems with inadequate welding. This situation usually requires multiple adjustments to the fixture and welding device, which not only reduces the welding efficiency, but also limits the application scope of the laser and plasma hybrid welding device. Summary of the invention

[0004] In view of this, the present invention provides a laser and plasma hybrid welding device, which can achieve the purpose of multi-dimensional automatic adjustment of the workpiece through the coordinated cooperation of a position adjustment mechanism, an adjustment component, a drive component and a height adjustment component, ensuring that workpieces with complex shapes can also be welded in place, thereby greatly improving the application scope of the laser and plasma hybrid welding device.

[0006] The adjustment component includes a toothed plate slidably connected between the two side walls of the inner cavity of the sliding plate. A semicircular gear is provided at the lower end of the swinging plate. The semicircular gear is meshed with the toothed plate. A screw rod is rotatably connected between the two ends of the inner cavity of the sliding plate. The screw rod is threadedly connected to the thread hole set in the middle of the toothed plate, thereby driving the swinging plate and its auxiliary mechanism to adjust the angle.

[0007] The adjustment component also includes a motor 1 arranged at one end of the sliding plate, and the output shaft of the motor 1 is fixedly connected to one end of the screw rod, which plays a role of rapid driving.

[0008] The invention also includes a driving component, which is used to drive the sliding plate to slide along the arc-shaped sliding groove. The driving component includes rotating plates symmetrically connected to the two ends of the upper side of the inner cavity of the rectangular frame plate. The lower ends of the rotating plates are fixedly connected to the sliding plates. A worm gear is provided at the outer end of the rotating plate away from the motor. A symmetrically distributed fixed plate is provided at one end of the rectangular frame plate close to the worm gear. A worm is rotatably connected between the two fixed plates.

[0009] The driving assembly also includes a second motor arranged on one side of the rectangular frame plate, and the output shaft of the second motor is fixedly connected to one end of the worm, that is, providing a driving source for the worm.

[0010] It also includes a height adjustment component, which is used to adjust the height of the sliding cylinder. The height adjustment component includes a rectangular groove set on the upper end surface of the fixed column, and a rectangular rod is provided on the top wall of the sliding cylinder.

A threaded rod is rotatably connected to the middle part of the assembly plate, and the threaded rod is threadedly connected to the screw hole set at the lower end of the rectangular rod, so as to adjust the overall height of the sliding cylinder and its auxiliary mechanisms.

When the inclination angle of the workpiece is to be adjusted, the motor 1 operates to drive the screw to rotate, and the threaded connection between the screw and the thread hole causes the tooth plate to move in the inner cavity of the sliding plate. In this process, the tooth plate is engaged with the semicircular gear, thereby driving the swing plate and its auxiliary mechanism to adjust the angle. When the worm is driven to rotate by the motor 2, the worm gear engaged with it drives the rotating plate and the sliding plate to slide along the arc-shaped groove, thereby achieving the purpose of automatic adjustment of the workpiece angle, ensuring that workpieces with complex shapes can also be welded in place, and achieving the purpose of multi-dimensional automatic adjustment of the workpiece, thereby greatly improving the application scope of the laser and plasma composite welding device.

[0024] like Figure 1-5 As shown:

[0025] The present embodiment provides a laser and plasma hybrid welding device, comprising a workbench 100 and a laser plasma hybrid welding machine 200 and a position adjustment mechanism respectively arranged at the upper end of the workbench 100, characterized in that: the position adjustment mechanism is used to adjust the position of the welding workpiece, a linear motor 1 300 is provided in the middle of the upper end of the workbench 100, a linear motor 2 301 is provided at the upper end of the movable element seat of the linear motor 1 300, a fixed column 302 is provided at the upper end of the movable element seat of the linear motor 2 301, a sliding cylinder 303 is slidably connected in the fixed column 302, a rectangular frame plate 304 is provided at the upper end of the sliding cylinder 303, arc-shaped slide grooves 305 are provided at both ends of the rectangular frame plate 304, a sliding plate 306 is slidably connected between the two arc-shaped slide grooves 305, a swing plate 307 is rotatably connected to the upper end of the inner cavity of the arc-shaped slide groove 305, a chuck 308 is provided at the upper end of the swing plate 307, and an adjustment component for adjusting the swing plate 307 is also provided in the sliding plate 306.

[0026] First, the workpiece to be welded is mounted on the chuck 308, and then the external controller controls the laser plasma hybrid welding machine 200 to operate according to the set trajectory, and then the optical welding head and the plasma welding head work together to perform high-precision welding on the workpiece. During this process, the external controller synchronously controls the linear motor 1 300 and the linear motor 2 301 to operate in sequence according to the required adjustments. When the horizontal position of the welding workpiece needs to be adjusted, the horizontal position of the fixed column 302 and its auxiliary mechanisms on the workbench 100 is adjusted through the combined movement of the linear motor 1 300 and the linear motor 2 301. The device can be positioned so as to accurately move the clamped workpiece to the desired position. When the inclination angle of the workpiece needs to be adjusted, the swing plate 307 and its auxiliary mechanisms are driven to adjust the angle, or the sliding plate 306 is driven to slide along the arc-shaped slide groove 305, so as to achieve the purpose of automatic adjustment of the workpiece angle, ensure that complex-shaped workpieces can also be welded in place, and achieve the purpose of multi-dimensional automatic adjustment of the workpiece, thereby greatly improving the application scope of the laser and plasma hybrid welding device. When the height of the workpiece needs to be adjusted, the overall height of the sliding cylinder 303 and its auxiliary mechanisms is adjusted to achieve the adjustment of the height of the workpiece.

[0027] like Figure 2-3 As shown, the adjustment component includes a toothed plate 400 slidably connected between the two side walls of the inner cavity of the sliding plate 306, a dovetail groove is provided between the two side walls of the inner cavity of the sliding plate 306 for providing sliding support for the toothed plate 400, a semicircular gear 401 is provided at the lower end of the swing plate 307, the semicircular gear 401 is meshingly connected with the toothed plate 400, a screw rod 402 is rotatably connected between the two ends of the inner cavity of the sliding plate 306, and the screw rod 402 is threadedly connected to the thread hole set in the middle of the toothed plate 400.

[0028] The screw rod 402 rotates, and the threaded connection between the screw rod 402 and the thread hole causes the tooth plate 400 to move in the inner cavity of the sliding plate 306. During this process, the tooth plate 400 meshes with the semicircular gear 401, thereby driving the swing plate 307 and its auxiliary mechanisms to adjust the angle.

[0029] like Figure 1-3 As shown, the adjustment component also includes a motor 403 disposed at one end of the sliding plate 306, and the output shaft of the motor 403 is fixedly connected to one end of the screw rod 402. When the motor 403 is in operation, it drives the screw rod 402 to rotate, thereby achieving a rapid driving effect.

[0030] like Figure 2-3As shown, it also includes a driving component, which is used to drive the sliding plate 306 to slide along the arc-shaped sliding groove 305. The driving component includes a rotating plate 500 that is symmetrically connected to the two ends of the upper side of the inner cavity of the rectangular frame plate 304. The lower ends of the rotating plates 500 are fixedly connected to the sliding plate 306. A worm gear 501 is provided at the outer end of the rotating plate 500 away from the end of the motor 403. A symmetrically distributed fixed plate 502 is provided at one end of the rectangular frame plate 304 close to the worm gear 501. A worm 503 is rotatably connected between the two fixed plates 502, and the worm 503 is meshed with the worm gear 501.

[0031] When the worm 503 is driven to rotate, the worm wheel 501 meshing with it drives the rotating plate 500 and the sliding plate 306 to slide along the arc-shaped slide groove 305, thereby realizing the purpose of automatic adjustment of the workpiece angle, ensuring that complex-shaped workpieces can also be welded in place, and realizing the purpose of multi-dimensional automatic adjustment of the workpiece, thereby greatly improving the application scope of the laser and plasma composite welding device. At the same time, the meshing connection relationship between the worm 503 and the worm wheel 501 is utilized to realize the self-locking function, ensuring that the workpiece remains in the adjusted position.

[0032] like Figure 2-3 As shown, the driving assembly also includes a second motor 504 arranged on one side of the rectangular frame plate 304. The output shaft of the second motor 504 is fixedly connected to one end of the worm 503. When the second motor 504 is in operation, the worm 503 is driven to rotate, providing a driving source for the worm 503.

[0033] like Figure 1-5 As shown, it also includes a height adjustment component, which is used to adjust the height of the sliding cylinder 303. The height adjustment component includes a rectangular groove 600 set on the upper end surface of the fixed column 302, and a rectangular rod 601 is provided on the top wall of the sliding cylinder 303. The rectangular rod 601 is slidably connected to the rectangular groove 600, and an assembly plate 602 is provided at the lower end of the rectangular groove 600.

[0034] When the height of the workpiece needs to be adjusted, the threaded connection between the threaded rod 603 and the threaded hole causes the rectangular rod 601 and its attachments to slide along the rectangular groove 600, thereby adjusting the overall height of the sliding cylinder 303 and its attachments.

[0035] like Figure 1-5 As shown, the height adjustment assembly also includes a motor three 604 disposed at the bottom of the rectangular groove 600, and the output shaft of the motor three 604 is fixedly connected to one end of the threaded rod 603. The motor three 604 operates to drive the threaded rod 603 to rotate, thereby achieving the driving purpose.

[0036] like Figure 1-3As shown, a telescopic protective cover 700 is provided between the rectangular frame plate 304 and the swing plate 307 , and the telescopic protective cover 700 plays a role of safety protection for the internal components thereof, and does not affect the angle adjustment of the workpiece.

[0037] The working principle of a laser and plasma hybrid welding device provided by the present invention is as follows: first, the workpiece to be welded is mounted on the chuck 308, and then the external controller controls the laser plasma hybrid welding machine 200 to operate according to the set trajectory, and then the optical welding head and the plasma welding head work together to perform high-precision welding on the workpiece. During this process, the external controller synchronously controls the linear motor 1 300, the linear motor 2 301, the motor 1 403, the motor 2 504 and the motor 3 604 to operate in sequence according to the required adjustments. When it is necessary to adjust the horizontal position of the welding workpiece, the horizontal position of the fixed column 302 and its auxiliary mechanism on the workbench 100 is adjusted through the combined movement of the linear motor 1 300 and the linear motor 2 301, so as to accurately move the clamped workpiece to the required position. When it is necessary to adjust the inclination angle of the workpiece, the motor 1 403 operates to drive the screw rod 402 to rotate, and the tooth plate 400 is affected by the threaded connection relationship between the screw rod 402 and the thread hole, so that the tooth plate 400 is moved on the sliding plate 306, during this process, the tooth plate 400 is meshed with the semicircular gear 401, thereby driving the swing plate 307 and its affiliated mechanisms to adjust the angle. When the worm 503 is driven to rotate by the motor 2 504, the worm wheel 501 meshed with it drives the rotating plate 500 and the sliding plate 306 to slide along the arc groove 305, so as to achieve the purpose of automatic adjustment of the workpiece angle, ensure that complex-shaped workpieces can also be welded in place, and achieve the purpose of multi-dimensional automatic adjustment of the workpiece, thereby greatly improving the application scope of the laser and plasma composite welding device, and the telescopic protective cover 700 plays a role of safety protection for its internal components, and does not affect the angle adjustment of the workpiece. When the height of the workpiece needs to be adjusted, the threaded rod 603 is driven to rotate by the motor 3 604. At this time, affected by the threaded connection relationship between the threaded rod 603 and the threaded hole, the rectangular rod 601 and its affiliated mechanisms slide along the rectangular groove 600, so as to adjust the overall height of the sliding cylinder 303 and its affiliated mechanisms.

[0038] 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.
