Description

Technical Field

[0001] This utility model relates to the field of laser welding and cleaning technology, specifically to a five-axis integrated laser welding and cleaning processing device. Background Technology

[0002] Sheet metal products often undergo multiple processes during manufacturing, including cutting, cleaning, and welding. Traditional pre-welding treatments primarily involve chemical cleaning or mechanical grinding. Chemical cleaning is inconsistent in its effectiveness and uses large amounts of chemicals, which can pollute the environment. Mechanical grinding is inefficient and can damage the workpiece surface. Laser cleaning, on the other hand, uses a high-energy laser beam to instantly vaporize or remove contaminants from the workpiece surface. Laser cleaning is efficient, environmentally friendly, and non-destructive to the workpiece. However, traditional welding and cleaning steps usually involve separate equipment. Therefore, operators need to move the workpiece between these steps. During this process, the cleaned workpiece may become re-contaminated, affecting the subsequent welding quality and wasting time and effort. For larger and heavier workpieces, moving them is difficult and may even result in damage during transport to the next equipment, leading to material waste. This single mode of movement is insufficient to meet the diverse needs of complex welding operations. Therefore, there is an urgent need in the market for equipment that can achieve high-precision and high-efficiency welding and cleaning, so that cleaning and welding can be effectively integrated to better meet the diverse needs of modern industrial manufacturing for precision machining equipment.

The rotating structure is located below the depth propulsion structure and the horizontal height of the rotating structure is lower than the horizontal height of the horizontal translation structure.

[0031] The horizontal translation structure includes a horizontal slide rail 21, a horizontal slider 22, and a horizontal traveling mechanism. The horizontal traveling mechanism includes a horizontal motor 23, a horizontal rack 24, and a horizontal gear 25. The horizontal slide rail 21 is fixed to the base frame 1 with screws. The length direction of the horizontal slide rail 21 is parallel to the X-axis. The horizontal rack 24 is fixedly disposed inside the horizontal slide rail 21 with its tooth surface facing laterally. The horizontal gear 25 meshes with the horizontal rack 24. The bottom of the horizontal slider 22 is designed as a dovetail block, which cooperates with the dovetail groove of the horizontal slide rail 21 to form a sliding pair contact, ensuring that the horizontal slider 22 can only move along the X-axis direction within the horizontal slide rail 21. A horizontal motor 23, which is a stepper motor, is installed on the horizontal slider 22. The output shaft of the horizontal motor 23 is connected to the shaft of the horizontal gear 25 through a coupling. Driven by the horizontal motor 23, the horizontal gear 25 rotates. During the rotation, due to the meshing action between the horizontal gear 25 and the horizontal rack 24, the horizontal gear 25 moves linearly along the horizontal rack 24. Guided and positioned by the dovetail block at the bottom of the horizontal slider 22, the horizontal slider 22 moves horizontally back and forth in a linear motion along the X-axis direction within the horizontal slide rail 21, driven by the horizontal gear 25.

[0032] The depth propulsion structure includes a depth slide rail 31, a first depth slider 35, a second depth slider 36, a first depth traveling mechanism, and a second depth traveling mechanism. The first depth traveling mechanism includes a first depth gear 33, a depth rack 32, and a first depth motor 37; the second depth traveling mechanism includes a second depth gear 34, a depth rack 32, and a second depth motor 38. The first and second depth traveling mechanisms share the depth rack 32. The depth slide rail 31 is bolted to the horizontal slider 22 and is perpendicular to the horizontal slide rail 21. The depth rack 32 is fixed inside the depth slide rail 31 and meshes with the first depth gear 33 and the second depth gear 34, respectively. The straight-line distance between the axis of the first depth gear 33 and the horizontal slide rail 21 is greater than the straight-line distance between the axis of the second depth gear 34 and the horizontal slide rail 21.

[0033] The bottom of the first depth slider 35 is designed as a dovetail block, which engages with the dovetail groove of the depth slide rail 31 to form a sliding pair, ensuring that the first depth slider 35 can only move along the Y-axis within the depth slide rail 31. A first depth motor 37, which is a stepper motor, is mounted on the first depth slider 35. The output shaft of the first depth motor 37 is connected to the shaft of the first depth gear 33 via a coupling. Driven by the first depth motor 37, the first depth gear 33 rotates. During rotation, due to meshing with the depth rack 32, the first depth gear 33 moves linearly along the depth rack 32. Guided and positioned by the dovetail block at the bottom of the first depth slider 35, the first depth slider 35, driven by the first depth gear 33, performs a reciprocating linear motion along the Y-axis within the depth slide rail 31.

[0034] The bottom of the second depth slider 36 is designed as a dovetail block, which engages with the dovetail groove of the depth slide rail 31 to form a sliding pair, ensuring that the second depth slider 36 can only move along the Y-axis within the depth slide rail 31. A second depth motor 38, a stepper motor, is mounted on the second depth slider 36. The output shaft of the second depth motor 38 is connected to the shaft of the second depth gear 34 via a coupling. Driven by the second depth motor 38, the second depth gear 34 rotates. During rotation, due to meshing with the depth rack 32, the second depth gear 34 moves linearly along the depth rack 32. Guided and positioned by the dovetail block at the bottom of the second depth slider 36, the second depth slider 36, driven by the second depth gear 34, performs a reciprocating linear motion along the Y-axis within the depth slide rail 31.

[0035] The vertical lifting structure includes a cleaning structure and a welding structure. The cleaning structure includes a laser cleaning head 3, a cleaning slide rail 41, a cleaning slider 43, and a cleaning traveling mechanism. The cleaning traveling mechanism includes a cleaning lead screw 42 and a cleaning motor 44. The welding structure includes a laser welding head 4, a welding slide rail 45, a welding slider 47, and a welding traveling mechanism. The welding traveling mechanism includes a welding lead screw 46 and a welding motor 48.

[0036] The cleaning slide rail 41 is fixedly mounted on the first depth slide rail 35 by bolts. The cleaning slide rail 41 is perpendicular to the horizontal slide rail 21 and the depth slide rail 31. The first depth slide rail 35 is provided with a cleaning screw 42, and a cleaning slider 43 is mounted on the cleaning screw 42. The cleaning slider 43 is provided with a thread that matches the cleaning screw 42. Since the thread of the cleaning slider 43 meshes with the thread of the cleaning screw 42, the cleaning slider 43 will move a distance of one screw pitch along the Z-axis every time the cleaning screw 42 rotates one revolution. The cleaning motor 44 is fixed on the first depth slider 35. The cleaning motor 44 is a stepper motor. The output shaft of the cleaning motor 44 is connected to the shaft of the cleaning screw 42 through a coupling. Driving the cleaning motor 44 causes the cleaning screw 42 to rotate. When the cleaning screw 42 rotates, the cleaning slider 43 can move up and down vertically along the Z-axis. A laser cleaning head 3 is fixedly installed on the cleaning slider 43, and the laser cleaning head 3 is parallel to the cleaning slide rail 41. When the cleaning motor 44 is operating, the laser cleaning head 3 can move up and down vertically along the Z-axis.

[0037] The welding slide rail 45 is fixedly mounted on the second depth slide rail 36 by bolts, and the welding slide rail 45 is arranged parallel to the cleaning slide rail 41. A welding screw 46 is provided on the second depth slide rail 36, and a welding slide 47 is mounted on the welding screw 46. The welding slide 47 has threads that match those of the welding screw 46. Because the threads of the welding slide 47 mesh with the threads of the welding screw 46, each time the welding screw 46 rotates one revolution, the welding slide 47 will move a distance of one thread pitch along the Z-axis. The welding motor 48 is fixed on the second depth slider 36. The welding motor 48 is a stepper motor. The output shaft of the welding motor 48 is connected to the shaft of the welding screw 46 through a coupling. Driving the welding motor 48 causes the welding screw 46 to rotate. When the welding screw 46 rotates, the welding slider 47 can move up and down vertically along the welding screw 46 in the Z-axis direction. A laser welding head 4 is fixedly installed on the welding slider 47. The laser welding head 4 is set parallel to the welding slide rail 45, and the laser welding head 4 and the laser cleaning head 3 are on the same straight line in the Y-axis. When the welding motor 48 is operating, the laser welding head 4 can move up and down vertically along the Z-axis direction.

[0038] The rotary structure includes a chuck body 51, movable jaws 52, a chuck motor 53, a rotary motor 54, and a turntable 55. The base of the turntable 55 is fixedly mounted on the cantilever 2. The chuck body 51 is fixedly mounted on the table surface of the turntable 55. The rotary motor 54 is located at the bottom of the turntable 55 and drives the turntable 55 to rotate. The chuck body 51 has several grooved rails, each grooved rail containing a movable jaw 52 for clamping the workpiece. The chuck motor 53 is located at the bottom of the turntable 55 and drives the movable jaws 52 to clamp and secure the workpiece. In this embodiment, three movable jaws 52 are evenly distributed on the chuck body 51, similar to a conventional electric three-jaw chuck.

[0039] The integrated five-axis laser cleaning and welding processing device also includes a controller, which is connected to the horizontal motor 23, the first depth motor 37, the second depth motor 38, the cleaning motor 44, the welding motor 48, the chuck motor 53, and the rotary motor 54. The controller can control the operation of each motor. The controller also controls the laser cleaning head 3 and the laser welding head 4.

[0040] When using:

[0041] First, place the workpiece on the chuck body 51, drive the chuck motor 53 so that the movable jaw 52 can clamp the workpiece; drive the rotary motor 54 so that the position to be cleaned and welded is horizontal with the Y axis.

[0042] Then, the controller controls the horizontal motor 23 to align the laser cleaning head 3 with the processing point in the horizontal direction (X-axis); the controller controls the first depth motor 37 and the second depth motor 38 to align the laser cleaning head 3 with the processing point in the depth direction (Z-axis); the distance between the laser welding head 4 and the laser cleaning head 3 is adjusted according to the different workpieces; the controller controls the cleaning motor 44 and the welding motor 48 to adjust the laser cleaning head 3 and the laser welding head 4 to a suitable cleaning and welding height in the vertical direction (Y-axis).

[0043] By controlling the first depth motor 37 and the second depth motor 38, the laser cleaning head 3 and the laser welding head 4 can move at a constant speed in the Z-axis, realizing a one-step process of cleaning first and then welding.

[0044] After the cleaning and welding work in the above step is completed, if there is another part that needs to be cleaned and welded, the rotary motor 54 is controlled to make the turntable 55 rotate to further drive the workpiece to rotate, and the next position to be processed is adjusted to a position that is horizontal with the Y axis, and the cleaning and welding work continues until all parts are cleaned and welded.

[0045] If the workpiece has been processed, control the chuck motor 53 to loosen the grip of the movable jaw 52 on the workpiece, and then remove the workpiece to complete the processing of the workpiece.

[0046] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
