[0023] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the detailed implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0024] Some embodiments of the present utility model will be described below in conjunction with the accompanying drawings,

[0025] Embodiment 1:

[0026] Combined with Figures 1-4 As shown, this embodiment provides a laser hybrid welding device, including: a main body mechanism 100 and a fixing mechanism 200.

[0027] Among them, the main body mechanism 100 includes symmetrically arranged columns 110, a base plate 120 fixed to the top ends of the columns 110, a guide seat 130 fixed to one side of the top end of the base plate 120, a hollow tube 140 movably passing through the guide seat 130, a laser welding gun 150 installed at one end of the hollow tube 140, a driving member 160 installed at the bottom end of the base plate 120, a connecting rod 170 connecting the driving member 160 and the other end of the hollow tube 140, and a filter member 180 fixed to the end of the hollow tube 140.

[0028] The column 110 is used to install the bottom plate 120 to ensure the stability of the bottom plate 120. The guide seat 130 is fixed to the top end of the bottom plate 120 and is used to install the hollow tube 140 and limit the movement of the hollow tube 140. The hollow tube 140 movably passes through the guide seat 130 and is used to install the laser welding gun 150 and drive the laser welding gun 150 to move, facilitating the laser welding gun 150 to extend into the inner cavity of the tubular workpiece.

[0029] The filter element 180 includes a housing 181 fixed to the end of the hollow tube 140 and communicating with the inner cavity of the hollow tube 140, a high-speed fan 182 installed on the inner wall of the housing 181, and an activated carbon filter screen 183 fixed to the inner wall of the housing 181. At the same time, a plurality of groups of through holes 141 are formed in an annular array on the outer side surface of the hollow tube 140 close to the laser welding gun 150. When the high-speed fan 182 is started, the air in the inner cavity of the hollow tube 140 is discharged to form a negative pressure. At this time, the welding fumes around the laser welding gun 150 will enter the hollow tube 140 through the through holes 141 under the action of air pressure, and then enter the activated carbon filter screen 183 along with the air flow and are discharged after being filtered by the activated carbon filter screen 183, which can effectively prevent the welding fumes from being discharged into the surrounding environment and affecting the health of workers.

[0030] The driving member 160 includes a fixed seat 161 symmetrically fixed to the bottom end of the bottom plate 120, a threaded rod 162 rotatably installed between the opposite fixed seats 161, a threaded sleeve 163 sleeved on the threaded rod 162, and a first motor 164 installed on one fixed seat 161 and having a shaft fixedly connected to the end of the threaded rod 162. At the same time, one end of the connecting rod 170 is fixedly connected to the threaded sleeve 163, and the other end is fixedly connected to the outer side surface of the end of the hollow tube 140. When the first motor 164 is started, it drives the threaded rod 162 to rotate. The rotation of the threaded rod 162 drives the threaded sleeve 163 to move. The movement of the threaded sleeve 163 drives the hollow tube 140 to move through the connecting rod 170, and the movement of the hollow tube 140 drives the laser welding gun 150 to move, enabling the laser welding gun 150 to extend into the tubular workpiece and facilitating the welding of the inner wall of the longer tubular workpiece.

[0031] The fixing mechanism 200 is used to fix the tubular workpiece and includes a sleeve 210 movably sleeved on the column 110, a triangular support plate 220 fixed to one side of the sleeve 210, a first electric telescopic rod 230 installed on one side of the bottom plate 120 and having an end fixedly connected to the sleeve 210, a support member 240 fixed to the top end of the triangular support plate 220, and a clamping member 250 installed on the triangular support plate 220 and located above the support member 240.

[0032] The sleeve 210 is used to install the triangular support plate 220 and limit the movement of the triangular support plate 220. The first electric telescopic rod 230 is used to drive the sleeve 210 to move up and down. The up and down movement of the sleeve 210 can synchronously drive the triangular support plate 220 to move up and down, that is, drive the tubular workpiece to move up and down, facilitating the laser welding gun 150 to approach the inner wall of the tubular workpiece.

[0033] The support member 240 is used to support the tubular workpiece, including a base 241 fixed to the top end of the triangular support plate 220, first rollers 242 symmetrically installed on both sides of the base 241, and a second motor 243 installed on the base 241 and fixedly connected to the shaft of one of the first rollers 242. The base 241 is used to install the first rollers 242. The first rollers 242 are used to support the tubular workpiece and facilitate the rotation of the tubular workpiece. The second motor 243 is used to drive the first rollers 242 to rotate, and the rotation of the first rollers 242 drives the tubular workpiece to rotate, facilitating the laser welding gun 150 to weld the inner wall of the tubular workpiece at different positions.

[0034] The clamping member 250 includes second electric telescopic rods 251 symmetrically fixed on both sides of the triangular support plate 220, a top seat 252 fixed to the top ends of the second electric telescopic rods 251, and second rollers 253 symmetrically installed at the bottom end of the top seat 252. When the second electric telescopic rods 251 contract, they drive the top seat 252 to move downward. The downward movement of the top seat 252 drives the second rollers 253 to move downward, enabling the second rollers 253 to press the tubular workpiece against the first rollers 242 to ensure the stability of the tubular workpiece.

[0035] Working principle and usage process of the present utility model: During use, pass the tubular workpiece through the support member 240 and the clamping member 250. Start the second electric telescopic rod 251. The second electric telescopic rod 251 contracts, driving the top seat 252 to move downward. The downward movement of the top seat 252 drives the second roller 253 to move downward, enabling the second roller 253 to press the tubular workpiece against the first roller 242 to ensure the stability of the tubular workpiece. Then, start the first motor 164, which drives the threaded rod 162 to rotate. The rotation of the threaded rod 162 drives the threaded sleeve 163 to move. The movement of the threaded sleeve 163 drives the hollow tube 140 to move through the connecting rod 170. The movement of the hollow tube 140 drives the laser welding gun 150 to move, so that the laser welding gun 150 extends into the tubular workpiece. When the laser welding gun 150 reaches the designated position, the first motor 164 is turned off. At this time, the first electric telescopic rod 230 extends, driving the sleeve 210 to move downward. The downward movement of the sleeve 210 drives the triangular support plate 220 to move downward, that is, drives the tubular workpiece to move downward, making the laser welding gun 150 closely attached to the inner wall of the tubular workpiece. Then, the laser welding gun 150 can weld the inner wall of the tubular workpiece. During welding, start the second motor 243, which drives the first roller 242 to rotate. The rotation of the first roller 242 drives the tubular workpiece to rotate, facilitating the laser welding gun 150 to weld the entire inner wall of the tubular workpiece. In addition, during welding, start the high-speed fan 182 to inhale the smoke generated during the welding of the laser welding gun 150 into the hollow tube 140 through the through hole 141 and discharge it after passing through the activated carbon filter screen 183, which can effectively collect and filter the smoke generated during welding.

[0036] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
