The motors of these components are then controlled to operate simultaneously, with the motor output shafts rotating to drive the two lead screws, which in turn drive the two guide blocks toward the center, adjusting the workpiece's angle and position. The motors stop when the workpiece's centerline is aligned with the center of each centering component. The other workpiece is then adjusted similarly to the previous one. Once the adjustments are complete, the edges of the two workpieces are aligned, allowing welding to proceed. Since the two workpieces are clamped separately by the centering structure, any shaking during welding can be avoided. This device improves centering efficiency and reduces welding errors.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0021] Example 1: Figure 1-Figure 2As shown, a centering structure includes a group of centering components 100. The number of centering components 100 is flexibly selected according to the length of the workpiece, and multiple centering components 100 are arranged along the length direction of the workpiece to be welded. Each centering component 100 includes a motor 1, a support platform 2, a reducer 3, two screw rods 4 and two guide blocks 5. The reducer 3 is arranged in the middle of the support platform 2, and the two screw rods 4 are symmetrically arranged on both sides of the reducer 3. The two screw rods 4 are respectively connected to the support platform 2 for rotation. The output shaft of the motor 1 is connected to the input end of the reducer 3. The reducer 3 is provided with two output ends, each output end is respectively connected to one end of one of the screw rods 4, each guide block 5 is respectively threadedly connected to one of the screw rods 4, and the two guide blocks 5 are respectively connected to the support platform 2 for sliding. When in use, the two workpieces are respectively centered by the two centering structures, the edges of the two workpieces are aligned, and then welding is performed by welding equipment, thereby improving the centering efficiency and reducing welding errors. The following is an example of the adjustment process of a workpiece: the workpiece is placed on the centering structure from above, and the workpiece is supported by multiple centering components 100. Then, the motors 1 of the multiple centering components 100 are controlled to work simultaneously. The output shaft of the motor 1 rotates to drive the two screws 4 to rotate synchronously, and then drives the two guide blocks 5 to move toward the middle to adjust the angle and position of the workpiece. When the center line of the workpiece and the center of each centering component 100 are in the same straight line, the motor 1 stops working. At this time, the two guide blocks 5 on each centering component 100 clamp the workpiece. The other workpiece is also adjusted according to the above operation. After the adjustment is completed, the edges of the two workpieces are aligned. Since the two workpieces are clamped separately by the centering structure, shaking of the workpieces during welding can be avoided.
[0022] like Figure 2 As shown, the support platform 2 includes a support seat 21, a first fixed seat 22, a second fixed seat and a guide plate 23. A cavity for accommodating the reducer 3 is opened in the middle of the support seat 21. The first fixed seat 22 and the second fixed seat are respectively provided on both sides of the cavity along the length direction of the support seat 21. The first fixed seat 22 and the second fixed seat are respectively fixed on the support seat 21. The two ends of the screw rod 4 are respectively rotatably connected to the first fixed seat 22 and the second fixed seat. The tops of the first fixed seat 22 and the second fixed seat are connected through the guide plate 23. The guide block 5 is slidably connected to the guide plate 23. During the movement of the guide block 5, it is guided by the guide plate 23.
[0023] like Figure 2 、 Figure 3As shown, guide rails 24 are symmetrically arranged on both sides of the guide plate 23. The two slide rails 24 are arranged along the length of the support base 21. A first slider and a second slider are arranged at the bottom of the guide block 5, and the first slider and the second slider are respectively slidably connected to one of the slide rails 24. Each slide rail 24 has a strip groove on both sides, and the length of the strip groove is the same as that of the slide rail 24. The middle of the first slider and the second slider respectively has a slide groove along the length of the slide rail 24. The bottom of each side of the first slider and the second slider is bent in the direction of the slide groove to form a protrusion, and each protrusion is slidably connected to one of the strip grooves. The provision of the first slider, the second slider, and the slide rails 24 makes the guide block 5 move more smoothly.
[0024] like Figure 2 As shown, the support seat 21 is surrounded by multiple support blocks 6 near the edge of the cavity. The multiple support blocks 6 form a rectangle, and the top surfaces of the multiple support blocks 6 are on the same plane. The multiple support blocks 6 support the workpiece to ensure the stability of the workpiece. Preferably, there are four support blocks 6. A limit block 7 is provided on the side of the guide block 5 near the reducer 3. The top surface of the limit block 7 is higher than the top surface of the support block 6. During the movement of the guide block 5, the limit block 7 guides the edge of the workpiece.
