[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further elaborates on the present utility model in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] Refer to Figures 1-3 A positioning and clamping mechanism for a perforated straight plate used in laser welding as shown, including a bottom plate 1. Both sides of the bottom plate 1 are hinged with rotating brackets 2. On both sides of each rotating bracket 2, a linear module 3 and a second carrier plate 4 are respectively fixedly connected. On the moving platform of each linear module 3, a first carrier plate 301 is fixedly connected. Positioning grooves are provided on both the first carrier plate 301 and the second carrier plate 4. A positioning rod 5 is fixedly connected in the positioning groove on the first carrier plate 301. The positioning groove and the positioning rod 5 are used to position and place the straight plate. Below the bottom plate 1, a servo motor 6 is fixedly connected beside each rotating bracket 2. The rotating bracket 2 passes through the bottom plate 1 at the hinged part with the bottom plate 1 and is fixedly connected with a driven gear 201. A driving gear 601 is fixedly connected to the rotating shaft of the servo motor 6. Below the second carrier plate 4 on the rotating bracket 2, a pressing cylinder 8 is fixedly connected. The pressing cylinder 8 is used to press one end of the straight plate to be welded.

[0017] A smoke exhaust hood 7 is fixedly connected between the two rotating brackets 2 on the bottom plate 1. The smoke exhaust hood 7 can suck out the waste gas generated during laser welding processing to avoid harm to the human body caused by the waste gas.

[0018] Arc-shaped grooves 101 are provided at both ends of each rotating bracket 2 on the bottom plate 1. At each arc-shaped groove 101, a guide wheel 202 is rotatably connected to the lower part of the rotating bracket 2. The guide wheel 202 can guide the rotation of the rotating bracket 2, and the guide wheel 202 is slidably connected with the arc-shaped groove 101.

[0019] The first carrier plate 301 is slidably connected with the rotating bracket 2. The rotating bracket 2 can guide the sliding of the first carrier plate 301. The pressing cylinder 8 is arranged in a dislocation manner with the positioning groove. The piston rod of the pressing cylinder 8 passes through the rotating bracket 2 and the second carrier plate 4 and is fixedly connected with a pressing plate 801.

[0020] The working principle of the present utility model is as follows: Before the present utility model is used, first adjust the position of the first carrier plate 301 according to the length of the straight plate, which can be adjusted by driving the first carrier plate 301 to slide on the rotating bracket 2 through the linear module 3; then adjust the angle of the rotating bracket 2 according to the angle of the inclined plane of the straight plate to ensure that the inclined cutting surfaces of the two straight plates can be completely fitted, which can be adjusted by driving the driving gear 601 to rotate through the servo motor 6 so as to drive the driven gear 201 and the rotating bracket 2 to rotate and adjust the angle.

[0021] When the utility model is in use, first, the piston rod of the pressing cylinder 8 extends, and the straight plate is placed on the first carrier plate 301 and the second carrier plate 4 along the positioning groove and the positioning rod 5. Then, the piston rod of the pressing cylinder 8 retracts, and the pressing plate 801 descends to press the straight plate. Thus, the positioning and clamping of the two straight plates are completed. Subsequently, the contact positions of the two straight plates are welded from top to bottom by a laser welding machine. The waste gas generated during the whole process is sucked out through Chu Yanzhou 7 (the smoke extraction hood 7 is connected to an external negative pressure fan or an air extraction pump for air extraction).
