Description

Technical Field

[0001] This utility model relates to the technical field of laser welding, specifically to a multi-station welding workbench for a laser welding machine. Background Technology

[0002] Laser welding is a welding method that uses a focused laser beam to bombard the workpiece, generating heat to weld components. Due to the optical properties of lasers, such as refraction and focusing, laser welding is ideal for welding miniature parts and areas with poor accessibility. Laser welding also features low heat input, minimal weld deformation, and is unaffected by electromagnetic fields.

[0003] Laser welding typically requires a corresponding worktable for assistance. Existing laser welding worktables, such as the one with patent publication number CN222269007U, have a lifting mechanism that allows for adjustment of the height of the workpiece support. This allows for workpiece height adjustment, and the workpiece can move freely along the positioning axis without needing to reposition the welding point, thus enabling free and rapid completion of irregular-shaped welding. Furthermore, by incorporating a tilt adjustment mechanism, the tilt angle of the hinged support plate can be adjusted via the extension and retraction of an electric telescopic rod, thereby adjusting the tilt of the workpiece on the support.

[0004] However, since there is only one workstation, the welding parts need to be changed frequently, resulting in low efficiency. Utility Model Content

[0025] Please see Figure 1-4A multi-station welding workbench for a laser welding machine includes a laser welding workbench 5, a support frame 1, a rotating constraint sleeve 2, a rotating shaft 3, a disc 4, a driven synchronous gear 6, a slot 7, a driving rotary motor 8, a driving gear 9, a connecting frame 10, a cylinder 11, and a pin 12. Multiple sets of laser welding workbenches 5 are evenly arranged around the top of the disc 4. The bottom center of the disc 4 is connected to the top of the rotating shaft 3. The outer wall of the middle of the rotating shaft 3 is rotatably connected to the inner wall of the rotating constraint sleeve 2. The outer side of the rotating constraint sleeve 2 is connected to the inner side of the top of the support frame 1. The bottom end of the rotating shaft 3 is connected to the middle of the top of the driven synchronous gear 6. The rear inner top of the support frame 1 is connected to the top of the driving rotary motor 8. The output end of the driving rotary motor 8 is connected to the middle of the top of the driving gear 9. The driving gear 9 and the driven synchronous gear 6 are in movable meshing. The outer side of the driven synchronous gear 6 is respectively arranged in the direction corresponding to each set of laser welding workbenches 5. There is a set of slots 7. The top of the support frame 1 is connected to the top of the cylinder 11 via the connecting frame 10. The output end of the cylinder 11 is movably provided with a pin 12, which is engaged with the slot 7. The support frame 1 provides overall support. The laser welding machine is located at the front and works with the laser welding worktable 5. The operator can position the workpiece in each set of laser welding worktables 5. The active rotary motor 8 is driven to rotate the active gear 9. The active gear 9 meshes with the driven synchronous gear 6. The driven synchronous gear 6 is connected to the rotating shaft 3, which rotates under the constraint of the rotating constraint sleeve 2. This drives the disc 4 to rotate, so that the laser welding worktable 5 with the workpiece being welded is in the front position. Then, with the connecting frame 10 fixedly connected, the cylinder 11 is driven to extend the pin 12, which is then engaged with the corresponding slot 7 in the laser welding worktable 5, thus fixing the position of the laser welding worktable 5.

[0026] It also includes a chamfered groove 13. Each set of slots 7 in the driven synchronous gear 6 is provided with a set of chamfered grooves 13 on the outer side. The chamfered grooves 13 can widen the outer side of the slots 7, making it easier for the pins 12 to be inserted into the slots 7, thus improving convenience.

[0027] It also includes an oil nozzle 14, with the upper rear part of the rotating constraint sleeve 2 connected to the inner side of the oil nozzle 14; oil can be injected into the inner wall of the rotating constraint sleeve 2 through the oil nozzle 14 for convenient lubrication and maintenance.

[0028] It also includes an oil filling cap 15, and the outer side of the oil filling nozzle 14 and the inner side of the oil filling cap 15 can be detachably installed; after the oil filling cap 15 is installed on the outer side of the oil filling nozzle 14, the inside of the oil filling nozzle 14 can be sealed and protected to prevent dust from entering and improve reliability.

[0029] It also includes an outer frame 16, a screw groove mounting bracket 17, a protective cover 18, through plates 19, and bolts 20. The inner top of the support frame 1 is connected to the top of the outer frame 16. Multiple sets of screw groove mounting brackets 17 are provided on the sides of the outer frame 16. A set of through plates 19 is provided on the outer top of the protective cover 18 corresponding to the position of each set of screw groove mounting brackets 17. Bolts 20 are movably installed in the through plates 19. The bolts 20 are detachably screwed into the screw groove mounting brackets 17. The protective cover 18 is covered on the bottom of the outer frame 16, so that each set of through plates 19 corresponds to a set of screw groove mounting brackets 17. Then the bolts 20 can be screwed into the screw groove mounting brackets 17 through the through plates 19, thereby connecting and fixing the protective cover 18 to the outer frame 16, providing external shielding and protection for the internal structure of the support frame 1, and improving reliability.

[0030] It also includes handles 21, with the middle parts of the left and right sides of the protective cover 18 respectively connected to the inner side of a set of handles 21; by holding the two sets of handles 21, the protective cover 18 can be moved, thereby facilitating loading, unloading and movement assistance, and improving convenience.

[0031] In summary, when a multi-station laser welding workbench of a laser welding machine is in use, it is supported as a whole by a support frame 1. The laser welding machine is positioned in the front-middle position and cooperates with the laser welding workbench 5 for welding. The operator can position the workpiece within each set of laser welding workbench 5. The active rotary motor 8 runs, causing the active gear 9 to rotate. The active gear 9 meshes with the driven synchronous gear 6, and the driven synchronous gear 6 connects to the rotating shaft 3, which rotates under the constraint of the rotating constraint sleeve 2, driving the disc 4 to rotate. This positions the laser welding workbench 5 with the workpiece to be welded in the front position. Then, under the fixed connection of the connecting frame 10, the cylinder 11 runs, causing the pin 12 to extend. The chamfered groove 13 can widen the outer side of the slot 7, making it easier for the pin 12 to be inserted into the slot 7, thereby allowing the pin 12 to be inserted. The slot 7 corresponding to the laser welding worktable 5 is connected to fix the position of the laser welding worktable 5. In addition, oil can be injected into the inner wall of the rotating constraint sleeve 2 through the oil injection nozzle 14 for convenient lubrication and maintenance. After the oil injection cap 15 is installed on the outside of the oil injection nozzle 14, the inside of the oil injection nozzle 14 can be sealed and protected to prevent dust from entering. By holding the two sets of handles 21, the protective cover 18 can be moved to cover the bottom of the outer frame 16, so that each set of through pieces 19 corresponds to a set of screw groove mounting brackets 17. Then, the bolts 20 can be passed through the through pieces 19 and screwed into the screw groove mounting brackets 17, thereby connecting and fixing the protective cover 18 to the outer frame 16, realizing external shielding and protection of the internal structure of the support frame 1. The wiring of the internal structure of the support frame 1 can be connected to the outside through the through groove 22 to avoid interference.
