[0029] Please refer to Figures 1 to 4 A hardware fitting double-station laser welding machine, comprising a base 1, a rotary table 2 is rotatably connected to the top of one side of the base 1, and a laser welding mechanism is arranged on the top of the other side of the base 1, wherein

[0030] The top of the rotary table 2 is fixedly connected with a support frame 7, the support frame 7 is symmetrically provided with a frame 8 near the top of both sides, the bottom of the frame 8 is provided with an upper die 9, the support frame 7 is provided with a mounting seat 10 near the bottom of both sides, the mounting seat 10 is provided with a lower die 11 corresponding to the top of the upper die 9, the upper die 9 is symmetrically provided with a positioning through hole 12, and the frame 8 is symmetrically provided with a guide groove 13 at both ends.

[0031] A guide rod 14 is fixedly connected to the top of the mounting base 10 corresponding to the guide groove 13. A transmission gear 15 is rotatably connected to the middle of the support frame 7 near the bottom. A rack 16 is fixedly connected to the bottom of the mounting base 10 corresponding to the transmission gear 15. A hydraulic rod 17 is installed on the top of one side of the turntable 2. The top of the hydraulic rod 17 is fixedly connected to the mounting base 10. The turntable 2 is driven by the drive mechanism to rotate.

[0032] When welding hardware parts, the hardware parts are placed between the upper mold 9 and the lower mold 11. The upper mold 9 and the lower mold 11 are brought closer together by the hydraulic rod 17. At the same time, the transmission gear 15 and the rack 16 drive another set of upper mold 9 and lower mold 11 to move away from each other, so that the workpiece on the other set of upper mold 9 and lower mold 11 can be replaced. The workpiece is clamped by the upper mold 9 and lower mold 11, and the welding point is positioned with the positioning through hole 12 to achieve precise welding. After the workpiece is welded, the turntable 2 is rotated by the drive mechanism to switch the positions of the two sets of upper mold 9 and lower mold 11. This dual-station laser welding device is set with two sets of stations. The positioning structure formed by the two sets of upper mold 9 and lower mold 11 is used alternately, which can make the laser welding mechanism work continuously while the workpiece is replaced, thereby effectively improving the working efficiency of the laser welding device.

[0033] Please see Figures 1 to 4 The laser welding mechanism includes a sliding frame 3. The sliding frame 3 is longitudinally slidably mounted on the top of the base 1 away from the turntable 2.

The sliding direction of the sliding frame 3 is parallel to the shorter side of the base 1, and the sliding direction of the sliding frame 3 is perpendicular to the sliding direction of the mounting frame 4. When welding is required on the workpiece (the sliding method of the sliding frame 3 and the mounting frame 4 is screw driven, which is existing technology and irrelevant to the technical problem to be solved in this solution. Therefore, existing technology is directly cited without detailed explanation of its structure and working principle), the sliding frame 3 slides longitudinally, driving the laser welding machine 6 to slide longitudinally synchronously. When the mounting frame 4 slides vertically, it drives the laser welding machine 6 to slide vertically synchronously, and the laser welding machine 6 moves laterally through the electric telescopic rod 5, thereby enabling the laser welding machine 6 to weld welding points at different positions.

[0035] Please refer to Figures 1 to 4 , the driving mechanism includes a first reversing gear 18, and the top of the turntable 2 close to the ring side is fixedly connected with the first reversing gear 18, and the top of the base 1 close to the side of the turntable 2 is provided with a motor 19, and the shaft end of the motor 19 is fixedly connected with a second reversing gear 20 corresponding to the first reversing gear 18, and the first reversing gear 18 is engaged with the second reversing gear 20, and when the motor 19 works, the second reversing gear 20 is driven to rotate, and the second reversing gear 20 drives the first reversing gear 18 to rotate through engagement, so that the first reversing gear 18 drives the turntable 2 to rotate, so as to exchange the positions of the two groups of lower dies 11 and the upper dies 9.

[0036] Working principle: when using the hardware double-station laser welding machine, as shown in Figures 1 to 4 , first, when welding hardware, place the hardware between the upper die 9 and the lower die 11, and make the upper die 9 and the lower die 11 close to each other through the hydraulic rod 17, and drive another group of upper dies 9 and lower dies 11 to move away from each other through the transmission gear 15 and the rack 16, and replace the workpiece on another group of upper dies 9 and lower dies 11, the workpiece is clamped by the upper die 9 and the lower die 11, and the positioning hole 12 is used for positioning the welding point, so as to achieve accurate welding, after the workpiece is welded, the turntable 2 is rotated by the driving mechanism, and the positions of the two groups of upper dies 9 and lower dies 11 are exchanged, the double-station laser welding device sets two stations, and the positioning structure formed by the two groups of upper dies 9 and lower dies 11 is used alternately, which can replace the workpiece while the laser welding mechanism continues to work, thereby effectively improving the working efficiency of the laser welding device, and when the workpiece needs to be welded, the sliding frame 3 slides longitudinally, driving the laser welder 6 to slide longitudinally synchronously, the mounting frame 4 vertically slides, driving the laser welder 6 to slide vertically synchronously, and the electric telescopic rod 5 drives the laser welder 6 to move horizontally, thereby driving the laser welder 6 to weld the welding points at different positions;

[0037] When the hydraulic rod 17 drives the corresponding lower die 11 to lift, the mounting base 10 drives another group of lower dies 11 to move in the opposite direction through the transmission gear 15 and the rack 16, and then a single hydraulic rod 17 can drive two groups of lower dies 11 to move in the opposite direction respectively, so that the workpiece can be conveniently welded, and another group of lower dies 11 can be conveniently moved downward to facilitate the replacement of the workpiece after welding, and when the motor 19 works, the second reversing gear 20 is driven to rotate, the second reversing gear 20 drives the first reversing gear 18 to rotate through meshing, and the first reversing gear 18 drives the rotary table 2 to rotate, so that the positions of the two groups of lower dies 11 and the upper die 9 can be exchanged.
