[0020] A welding device of the present utility model includes a welding table 101, a laser welding machine 102 and a limiting component 103. The limiting component 103 includes a workbench 104, an outer arc clamping plate 105, a cross guide rail 106, a sliding plate 107, an inner arc top plate 108, a positioning member 109, a completion area 110, a to-be-processed area 111 and a partition plate 112. The workbench 104 includes a mounting frame 113, a placing table 114 and positioning bolts 115. The outer arc clamping plate 105 includes a fixing plate 116, a driving cylinder 117 and an arc plate 118. Through the foregoing solution, the problem that the limiting rod of the existing annular workpiece welding device is in point contact with the annular workpiece, and it is easy to cause the outer circle roundness of the two annular workpieces not to be maintained due to improper contact position of the limiting rod, resulting in welding deviation, is solved.

[0021] For this specific embodiment, the laser welding machine 102 is arranged on one side of the welding table 101. By starting the laser welding machine 102 arranged on the welding table 101, two workpieces can be connected into a complete workpiece. The specific structure and usage method of the laser welding machine 102 are detailed in the patent with the publication number CN220943676U, which is not the protection scope of this application and will not be elaborated here.

[0022] The workbench 104 is fixedly connected to the welding table 101 and is located on the top of the welding table 101. The outer arc clamping plate 105 is fixedly connected to the workbench 104 and is located on the side of the workbench 104. The cross guide 106 is fixedly connected to the workbench 104 and is located on the top of the workbench 104. The sliding plate 107 is slidably connected to the cross guide 106 and is slidably connected to the workbench 104 and is located on one side of the cross guide 106. The inner arc top plate 108 is fixedly connected to the sliding plate 107 and is located on the side of the sliding plate 107. The positioning member 109 is threadedly connected to the sliding plate 107 and passes through the sliding plate 107. When two semicircular workpieces need to be welded into a complete annular workpiece, the workpiece is first placed on the workbench 104 so that its outer ring is in contact with the outer arc clamping plate 105. At this time, the staff slides the sliding plate 107 in the cross guide 106 to push the inner The arc top plate 108 moves so that the inner arc top plate 108 can abut against the inner circle of the workpiece, and the positioning piece 109 is right-turned. The positioning piece 109 passes through the sliding plate 107 and abuts against the workbench 104, so that the position of the sliding plate 107 is fixed, and the position of the inner arc top plate 108 is fixed accordingly, and can cooperate with the outer arc clamping plate 105 to completely abut the workpiece, and the outer arc clamping plate 105 and the inner arc top plate 108 are in surface contact with the annular workpiece composed of two semicircular workpieces, which can effectively fix the position of the workpiece to avoid deviation. After the workpiece is fixed, the laser welding machine 102 arranged on the welding table 101 can be started, and the two semicircular workpieces on the workbench 104 can be welded to form a complete annular workpiece, so that the existing annular workpiece welding device has a point contact with the annular workpiece, which is easy to fail to maintain the outer circle roundness of the two annular workpieces due to improper contact position of the limiting rod, thereby causing the problem of welding deviation.

[0023] Secondly, the finishing area 110 is fixedly connected to the welding table 101 and is located on the left side of the welding table 101. The processing area 111 is fixedly connected to the welding table 101 and is located on the right side of the welding table 101. Workers can take out the semicircular workpieces to be welded from the processing area 111, and after welding the two semicircular workpieces into a complete annular workpiece, they can place it in the finishing area 110 to facilitate subsequent transfer and processing by the staff.

[0024] Again, the partition plate 112 is fixedly connected to the processing area 111 and is located in the processing area 111. The semicircular workpieces are placed left and right through the partition plate 112 in the processing area 111, which is convenient for staff to take them directly and avoids the workpieces being placed in a mess and needing to be sorted by staff.

[0025] In addition, the mounting bracket 113 is slidably connected to the welding table 101 and is located on one side of the welding table 101. The placing table 114 is fixedly connected to the mounting bracket 113 and is located on the top of the mounting bracket 113. The positioning bolt 115 is threadedly connected to the welding table 101 and passes through the mounting bracket 113. When welding some workpieces with larger sizes that exceed the range of the outer arc clamping plate 105, the staff can rotate the positioning bolt 115 counterclockwise, take out the positioning bolt 115 from the welding table 101, and then no longer fix the mounting bracket 113, which facilitates the staff to remove the placing table 114 from the welding table 101, replace the placing table 114 with a suitable size, and replace the outer arc clamping plate 105 and the inner arc top plate 108 accordingly, thereby facilitating the fixation of larger-sized workpieces.

[0026] Meanwhile, the fixing plate 116 is fixedly connected to the placing table 114 and is located on one side of the placing table 114. The driving cylinder 117 is fixedly connected to the fixing plate 116 and is located on one side of the fixing plate 116. The arc plate 118 is fixedly connected to the output end of the driving cylinder 117 and is located on the side of the driving cylinder 117 away from the fixing plate 116. When welding some smaller workpieces, first make the outer ring of the workpiece contact the arc plate 118, and start the driving cylinder 117 on the fixing plate 116. The output end of the driving cylinder 117 pushes the arc plate 118 to move, so that the arc plate 118 pushes the workpiece to move, and the workpiece can be pushed to the position where the inner ring contacts the inner arc top plate 108, thereby fixing the position of the smaller workpiece and facilitating its welding process.

[0027] A welding device of the present utility model. When two semi-circular workpieces need to be welded into a complete ring-shaped workpiece, the operator can take out the semi-circular workpiece to be welded from the processing area 111, first place the workpiece on the workbench 104 so that its outer ring contacts the arc plate 118. At this time, the operator slides the sliding plate 107 in the cross guide rail 106 to push the inner arc top plate 108 to move, so that the inner arc top plate 108 can abut against the inner ring of the workpiece, and then rotate the positioning member 109 clockwise. The positioning member 109 passes through the sliding plate 107 and abuts against the workbench 104, so that the position of the sliding plate 107 is fixed, and the position of the inner arc top plate 108 is fixed accordingly, which can cooperate with the arc plate 118 to completely abut against the workpiece. The arc plate 118 and the inner arc top plate 108 are in surface contact with the ring-shaped workpiece composed of two semi-circular workpieces, which can effectively fix the position of the workpiece and avoid deviation. After the workpiece is fixed, the laser welding machine 102 provided on the welding table 101 can be started to weld the two semi-circular workpieces on the workbench 104 to make them into a complete ring-shaped workpiece and place it in the completion area 110, which is convenient for the operator to perform subsequent transfer processing. When welding some workpieces with larger sizes exceeding the range of the outer arc clamping plate 105, the operator can rotate the positioning bolt 115 counterclockwise, take out the positioning bolt 115 from the welding table 101, and then no longer fix the mounting frame 113, which is convenient for the operator to remove the placing table 114 from the welding table 101 and replace the placing table 114 with a suitable size. The outer arc clamping plate 105 and the inner arc top plate 108 are replaced accordingly, which is convenient for fixing larger-sized workpieces. When welding some smaller workpieces, first make the outer ring of the workpiece contact the arc plate 118, and start the driving cylinder 117 on the fixing plate 116. The output end of the driving cylinder 117 pushes the arc plate 118 to move, so that the arc plate 118 pushes the workpiece to move, and the workpiece can be pushed to the position where its inner ring contacts the inner arc top plate 108, thereby fixing the position of the smaller workpiece and facilitating its welding process. Therefore, the existing ring-shaped workpiece welding device has a problem that the limiting rod and the ring-shaped workpiece are in point contact, and it is easy to cause the welding deviation due to the improper contact position of the limiting rod and the inability to maintain the roundness of the outer ring of the two ring-shaped workpieces.
