Description

Technical Field

[0001] The utility model relates to stainless steel pipe processing equipment, more specifically, it relates to a stainless steel pipe laser welding machine. Background Art

[0002] The stainless steel pipe laser welding machine mainly uses the laser beam as a heat source, and by focusing and transmitting the laser beam, the laser is accurately irradiated on the welding part. When the laser beam irradiates the surface of the stainless steel pipe, it will quickly heat and melt the stainless steel material to form a molten pool.

[0003] When the existing stainless steel tube laser welding machine is used, it is necessary to rotate the stainless steel tube when it is necessary to weld the entire circumference evenly, or to improve the welding quality and reduce welding defects. Rotating the stainless steel tube can make the laser beam evenly irradiate the entire welding area, ensuring the quality and consistency of the welded joint. The existing stainless steel tube laser welding requires the stainless steel tube to be rotated, but currently only one end of the stainless steel tube can be rotated, and both cannot be rotated at the same time. Since the two stainless steel tubes cannot be rotated at the same time, it is difficult to ensure that the relative position and angle between them are always consistent during the adjustment process. This leads to deviation or misalignment at the welded joint, and repeated adjustments are required to achieve the ideal welding effect.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a laser welding machine for stainless steel pipes, in which the second gear drives the two first gears meshing with it to rotate. Since the pipe body is fixed to the first gear by the clamping positioning block, the first gear can drive the left and right pipe bodies to rotate at the same time when it rotates, which is convenient for adjusting the position of the pipe body. The two pipe bodies rotate at the same time to ensure that the relative position and angle between them are always consistent, thereby preventing misalignment deviation at the welding point and ensuring the welding effect.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a stainless steel tube laser welding machine, including a workbench, a support platform is fixedly installed on the left and right sides of the upper end of the workbench, a tube body is placed on the upper ends of the two support platforms, a positioning groove is opened on the left and right sides of the upper end of the workbench, a first gear is movably connected in the two positioning grooves, a limit frame is arranged on the left and right sides of the two first gears, the limit frame is fixedly connected to the workbench, a baffle is fixedly installed on the upper ends of the two groups of limit frames, a laser welder is fixedly installed on the middle side of the upper end of the baffle, a driving assembly is arranged at the lower end of the workbench, a second gear is fixedly installed on the left and right sides of the outer surface of the driving assembly, and the second gear is meshed with the first gear.

[0007] The utility model is further configured as follows: the driving assembly includes a fixing plate, two fixing plates are provided, and the opposite surfaces of the two fixing plates are movably connected with a driving shaft, and the right end of the driving shaft is fixedly installed with a driving motor.

[0008] The utility model is further configured as follows: a cylinder is fixedly installed on both the front and rear sides of the inner wall of the first gear, a positioning block is fixedly installed on the output ends of the two cylinders, and the tube body is located in the middle of the opposite surfaces of the two positioning blocks.

[0009] The utility model is further configured as follows: four supporting legs are fixedly installed at the lower end of the workbench.

[0010] The utility model is further configured as follows: the limiting frame is configured in a U shape.

[0011] In summary, the utility model has the following beneficial effects:

[0012] 1. The second gear drives the two first gears meshing with it to rotate. Since the tube body is fixed to the first gear by the clamping position of the positioning block, the first gear can drive the left and right tube bodies to rotate at the same time when it rotates, which is convenient for adjusting the position of the tube body. The two tube bodies rotate at the same time to ensure that the relative position and angle between them are always consistent, prevent misalignment at the welding point, and ensure the welding effect.

[0021] A stainless steel tube laser welding machine, such as Figures 1 to 3 As shown, it includes a workbench 1, a support platform 2 is fixedly installed on the left and right sides of the upper end of the workbench 1, a tube body 3 is placed on the upper ends of the two support platforms 2, a positioning groove 4 is opened on the left and right sides of the upper end of the workbench 1, a first gear 5 is movably connected in the two positioning grooves 4, a limit frame 6 is arranged on the left and right sides of the two first gears 5, the limit frame 6 is arranged in a U shape, the limit frame 6 is fixedly connected to the workbench 1, a baffle 7 is fixedly installed on the upper ends of the two groups of limit frames 6, a laser welder 8 is fixedly installed on the middle side of the upper end of the baffle 7, a driving component 9 is arranged at the lower end of the workbench 1, a second gear 10 is fixedly installed on the left and right sides of the outer surface of the driving component 9, the second gear 10 is meshed with the first gear 5, and the two tube bodies 3 are respectively placed on the left and right support platforms 2 , and are respectively located in the left and right first gears 5. By starting the cylinder 11 respectively, the left and right tube bodies 3 are clamped and positioned when the positioning block 12 moves. In order to ensure that the stainless steel tube body 3 does not shift during welding and achieve accurate welding, the first gear 5 is respectively restricted by the limit frame 6 and the top baffle 7, and is located in the positioning groove 4 to prevent the first gear 5 from positional displacement when rotating. The joint between the two tube bodies 3 is welded by the laser welder 8. Since the tube body 3 is fixed to the first gear 5 by the clamping positioning of the positioning block 12, the first gear 5 can drive the left and right tube bodies 3 to rotate at the same time when it rotates, which is convenient for adjusting the position of the tube body 3. The two tube bodies 3 rotate at the same time to ensure that the relative position and angle between them are always consistent, prevent misalignment at the welding point, and ensure the welding effect.

[0022] Four supporting legs 13 are fixedly mounted on the lower end of the workbench 1 , and the supporting legs 13 provide support for the workbench 1 .

[0023] like Figure 2 As shown, the driving assembly 9 includes a fixed plate 91, two fixed plates 91 are provided, and the opposite surfaces of the two fixed plates 91 are movably connected with a driving shaft 92. A driving motor 93 is fixedly installed on the right end of the driving shaft 92. The driving motor 93 drives the driving shaft 92 to rotate, thereby driving the two second gears 10 to rotate in one direction at the same time, and then drives the two first gears 5 meshing therewith to rotate.

[0024] like Figure 3 As shown, a cylinder 11 is fixedly installed on both sides of the front and rear of the inner wall of the first gear 5, and a positioning block 12 is fixedly installed on the output ends of the two cylinders 11. The tube body 3 is located in the middle of the opposite surfaces of the two positioning blocks 12. By starting the cylinders 11 respectively, the positioning blocks 12 are moved to clamp and position the left and right tube bodies 3 respectively, in order to ensure that the stainless steel tube body 3 does not shift during welding, and to achieve accurate welding.

[0025] Working principle: by placing two tube bodies 3 on the left and right support platforms 2 respectively, and respectively located in the left and right first gears 5, by starting the cylinder 11 respectively, the left and right tube bodies 3 are clamped and positioned when the positioning block 12 moves. In order to ensure that the stainless steel tube body 3 does not shift during welding and achieve accurate welding, the first gear 5 is respectively restricted by the limit frame 6 and the top baffle 7, and is located in the positioning groove 4 to prevent the first gear 5 from shifting when the position is rotated. The joint between the two tube bodies 3 is welded by the laser welder 8. When the position of the tube body 3 needs to be adjusted, the driving motor 93 drives the driving shaft 92 to rotate, thereby driving the two second gears 10 to rotate in one direction at the same time, and then driving the two first gears 5 meshing therewith to rotate. Since the tube body 3 is fixed to the first gear 5 by the clamping positioning of the positioning block 12, the first gear 5 can simultaneously drive the left and right tube bodies 3 to rotate at the same time when it rotates, which is convenient for adjusting the position of the tube body 3. The two tube bodies 3 rotate at the same time to ensure that the relative position and angle between them are always consistent, prevent misalignment at the welding point, and ensure the welding effect.
