Description

Technical Field

[0001] This utility model relates to the field of cylindrical welding equipment technology, and in particular to an auxiliary device for laser composite welding. Background Technology

[0002] Welding roller frames are mainly used to assist welding operations, especially in welding cylindrical workpieces, where they play an important role. They drive the cylindrical workpiece to rotate through the friction between the rollers and the workpiece, enabling horizontal welding of the inner and outer circumferential seams and the inner and outer longitudinal seams. When used in conjunction with laser composite automatic welding equipment, welding roller frames can significantly improve welding quality and efficiency.

[0003] However, existing welding roller frames can generally only drive the roller to rotate. However, rotation can only adjust the welding position on the cylindrical surface. When the welding robot arm extends into the inside of the roller, if the length of the welding robot arm is insufficient, it will not be able to completely cover the longitudinal length inside the roller. Since the existing welding roller frame cannot drive the roller to move longitudinally, some longitudinal areas cannot be welded. Based on this, an auxiliary device for laser composite welding is proposed to solve the above problems. Utility Model Content

[0004] To solve the technical problem of longitudinal movement in cylindrical welding, this utility model provides an auxiliary device for laser composite welding.

[0005] This utility model is achieved using the following technical solution: an auxiliary device for laser composite welding, comprising a base, with multiple limiting platforms fixedly connected to the upper side of the base, each limiting platform having a dovetail groove, and a dovetail slider slidably connected to the inner side of each dovetail groove, with a moving platform fixedly connected to the upper side of the multiple dovetail sliders, a longitudinal drive mechanism for moving back and forth being provided on the lower side of the moving platform, and a roller rotation drive mechanism being provided on the upper side of the moving platform.

[0006] As a further improvement to the above solution, the longitudinal drive mechanism includes limiting plates that are fixedly connected to both sides of the base, a threaded rod that is rotatably connected between the two limiting plates, a threaded sleeve that is fixedly connected to the lower side of the moving platform, and the threaded rod and the threaded sleeve being threadedly engaged.

[0007] As a further improvement to the above solution, a handwheel is fixedly connected to the end of the threaded rod away from the base.

[0008] As a further improvement to the above solution, the roller self-rotation drive mechanism includes two pairs of card seats fixedly connected to the upper side of the moving platform, and each pair of card seats is rotatably connected to a rotating shaft, one end of which is provided with a motor drive mechanism.

[0009] As a further improvement to the above solution, each of the rotating shafts is fixedly connected with multiple rollers, and the multiple rollers are simultaneously configured to cooperate with the side of the welding drum.

[0010] As a further improvement to the above solution, the motor drive mechanism includes a servo motor fixedly connected to one side of the mobile platform, and the output end of the servo motor is fixedly connected to one end of the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a handwheel to drive the threaded rod to rotate, thereby enabling the moving table to move back and forth along the inside of the dovetail groove. When the length of the laser welding arm is insufficient to reach the entire longitudinal area inside the drum, the moving table can be driven to move closer to the laser welding robot arm, so that the laser welding arm can weld and cover the entire area inside the drum.

[0013] 2. This utility model uses a dovetail groove and a dovetail slider on the limiting platform to load heavy roller workpieces onto the moving platform and provide limiting support. It has the advantages of high stability and strong wear resistance, and can effectively extend the service life of the welding auxiliary device. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example:

[0021] Please combine Figures 1-3This embodiment of an auxiliary device for laser composite welding includes a base 1. In this embodiment, two limiting platforms 4 are fixedly connected to the upper side of the base 1. In other embodiments, the number of limiting platforms 4 can be adjusted according to the size of the heavy workpiece. Each limiting platform 4 is provided with a dovetail groove 5. A dovetail slider 8 is slidably connected to the inner side of each dovetail groove 5. A moving platform 2 is fixedly connected to the upper side of the two dovetail sliders 8. A longitudinal drive mechanism for moving back and forth is provided on the lower side of the moving platform 2. A roller rotation drive mechanism is provided on the upper side of the moving platform 2.

[0022] The dovetail slider 8 moves within the dovetail groove 5, providing limiting support for the moving platform 2, resulting in greater stability. At the same time, its wear resistance helps to improve the service life of the auxiliary equipment.

[0023] Please combine Figure 1 As shown, the longitudinal drive mechanism includes limiting plates 10 that are fixedly connected to both sides of the base 1, a threaded rod 6 that is rotatably connected between the two limiting plates 10, and a threaded sleeve 13 that is fixedly connected to the lower side of the moving table 2. The threaded rod 6 and the threaded sleeve 13 are threadedly connected.

[0024] With the above technical solution, when the threaded rod 6 rotates forward, the moving table 2 moves to one side; conversely, when the threaded rod 6 rotates backward, the moving table 2 moves to the other side.

[0025] As shown in Figure 1, a handwheel 7 is fixedly connected to the end of the threaded rod 6 away from the base 1. The torque is amplified through the handwheel 7, which can reduce the operating burden of the staff.

[0026] Please combine Figure 2 As shown, the roller self-rotation drive mechanism includes two pairs of card seats 11 fixedly connected to the upper side of the moving platform 2. The card seats 11 and the moving platform 2 are detachable. Each pair of card seats 11 is rotatably connected to a rotating shaft 3. One end of one of the rotating shafts 3 is equipped with a motor drive mechanism.

[0027] Please combine Figure 2 As shown in this embodiment, each rotating shaft 3 is fixedly connected to two rollers 12, and the two rollers 12 are simultaneously configured to cooperate with the side of the welding drum.

[0028] Please combine Figure 1 As shown, the motor drive mechanism includes a servo motor 9 fixedly connected to one side of the moving table 2. The output end of the servo motor 9 is fixedly connected to one end of the rotating shaft 3. The linear speed of the drum rotation can be precisely set through the servo motor 9. When used in conjunction with the laser welding arm, the welding efficiency can be significantly improved.

[0029] The implementation principle of an auxiliary device for laser composite welding in this embodiment is as follows: Using a lifting device, the heavy roller to be welded is first placed between multiple rollers 12. When it is necessary to adjust the welding position on the cylindrical side of the roller 12, the servo motor 9 is started. The servo motor 9 drives the rotating shaft 3 to rotate, and then the rotating shaft 3 drives the roller 12 on one side to rotate. The roller 12 pushes the roller to rotate by friction with the roller, thereby setting the welding position on the side surface of the roller. When the welding robot arm is not long enough to reach the longitudinal length of the roller, the handwheel 7 is manually turned to drive the threaded rod 6 to rotate. The threaded rod 6 pushes the threaded sleeve 13 and the moving table 2 to move to one side. The dovetail slider 8 moves to one side along the dovetail groove 5 in the limiting table 4, so that the moving table 2 of the loaded roller moves closer to one side of the laser welding arm, so that the laser welding device can fully cover the longitudinal length of the roller.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
