Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1:

[0022] A pipe body fixing device for rectangular pipe seam welding, as described in this embodiment... Figure 1-3 As shown, the device includes a workbench 1 and a drive motor 17. A first rubber roller shaft 2 is symmetrically distributed and rotatably mounted on the outer wall of one top end of the workbench 1. A rectangular through groove 3 is opened through the outer wall of the top of the workbench 1. Sliding grooves 4 are opened through the inner walls of both sides of the rectangular through groove 3. Sliding blocks 5 are slidably inserted into the inner wall of the sliding grooves 4. A fixing plate 6 is welded between the two sliding blocks 5. A second rubber roller shaft 7 is rotatably mounted on the top of the fixing plate 6. An electric telescopic rod 12 is fixed to the outer wall of the top of the workbench 1 by bolts. A fixed top plate 13 is connected to the piston rod at the top of the electric telescopic rod 12. A connecting plate 15 is connected to the bottom of the fixed top plate 13 by a damping spring shock absorber 14.

[0023] The position of the fixing plate 6 is adjusted by using the adjusting screw 11 to drive the fixing plate 6, so that the distance between the second rubber roller shaft 7 and the first rubber roller shaft 2 can be quickly adjusted. This allows the device to be adapted to clamp and fix rectangular tubes of various sizes. In addition, the servo motor 10 at the bottom can drive the rectangular tube to move in clamping, improving the flexibility of the fixing device.

[0024] The bottom outer wall of the second rubber roller shaft 7 is welded with a belt gear 8, and a synchronous belt 9 is meshed between the belt gears 8. A servo motor 10 is connected to the bottom shaft of the belt gear 8. An adjusting screw 11 is rotatably installed in the middle of the fixed plate 6, and an adjusting block is welded to the outer wall of the adjusting screw 11.

[0025] A grinding wheel 16 is rotatably mounted at the center of the connecting plate 15, and a drive motor 17 is connected to the top axis of the grinding wheel 16.

[0026] After the weld seam of the rectangular tube is completed, in order to improve the overall quality, the electric telescopic rod 12 is used to drive the height-adjustable grinding wheel 16 to grind the surface slag of the weld seam, thereby reducing the intensity of subsequent work.

[0027] In this embodiment, the fixing device is first assembled. After assembly, the device is connected to an external power source. Then, the rectangular tube to be welded and fixed is placed on the top of the workbench 1. The adjusting screw 11 is then rotated, which causes the fixing plate 6 to slide and move the two second rubber roller shafts 7 closer to the first rubber roller shaft 2, thereby quickly clamping and fixing the rectangular tube. After clamping, the servo motor 10 at the bottom is started to adjust and advance the rectangular tube. After fixing, the seam of the rectangular tube is welded. The weld slag on the surface is then adjusted by the electric telescopic rod 12 to drive the grinding wheel 16 to adjust its position, and the drive motor 17 is started to drive the grinding wheel 16 to rotate, thereby grinding the weld slag and reducing the amount of subsequent processing work.

[0028] Example 2:
