[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] refer to Figure 1-Figure 3 The pipe seam alignment mechanism for laser welding of metal pipes shown in the figure includes a base 1, a first cylinder 2 and a second cylinder 3. The base 1 is provided with a pipe limiting plate 4 and a clamping cylinder 5. The pipe limiting plate 4 is provided with a C-shaped groove 401. The piston rod of the clamping cylinder 5 is fixedly connected with a head 501, and the head 501 is located in the limiting plate 4. An adjustable blocking component is provided on the side of the limiting plate 4. The adjustable blocking component includes a sliding bracket 601, a screw rod 602 and a blocking arm 603. The piston rod of the first cylinder 2 is fixedly connected with a lifting seat 201, and the lifting seat 201 is provided with a rubber roller 202 and a motor 203. The piston rod of the second cylinder 3 is fixedly connected with a laser sensor 7, and the laser sensor 7 passes through.

[0016] The pipe limiting plate 4 and the clamping cylinder 5 are both fixedly connected to the base 1 . The upper end of the mandrel 501 is provided with an arc surface. The pipe limiting plate 4 can limit the metal pipe to prevent the metal pipe from deflecting.

[0017] The screw rod 602 is rotatably connected to the limit plate 4, and the sliding bracket 601 is slidably connected to the limit plate 4. The limit plate 4 can guide the sliding bracket 601. The blocking arm 603 is fixedly connected to the sliding bracket 601. The sliding bracket 601 is threadedly connected to the screw rod 602. By rotating the screw rod 602, the sliding bracket 601 can be driven to slide and adjust.

[0018] The rubber roller 202 is rotatably connected to the lifting base 201, and the motor 203 is fixedly connected to the lifting base 201. When the motor 203 drives the rubber roller 202 to rotate, the metal tube is driven to rotate by friction. The rotating shaft of the motor 203 is connected to the rubber roller 202 through a transmission component.

[0019] The working principle of the present invention is as follows: before using the present invention, first adjust the position of the blocking arm 603 according to the length of the metal tube, and slide the sliding bracket 601 to a suitable position by rotating the screw rod 602. When using the present invention, put the metal tube along the C-shaped groove 401 until it contacts the blocking arm 603, and then the first cylinder 2 drives the lifting seat 201 to rise so that the rubber roller 202 fits the metal tube, and the second cylinder 3 drives the laser sensor 7 to rise to the detection position, and then the motor 203 drives the rubber roller 202 to rotate slowly. During this process, the laser sensor 7 stops rotating when it detects a gap. At this time, the clamping 5 drives the head 501 to tighten the metal tube, and then the first cylinder 2 and the second cylinder 3 are reset before laser welding processing can be carried out.

[0020] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
