[0041] Furthermore, the fixing plate 324 drives the inserting plate 323 to be inserted into the slot 322, so that the fixing plate 324 drives the clamping ring 325 to clamp and fix one end of the tubular workpiece. Different clamping rings 325 can be replaced according to the clamping of workpieces of different shapes or sizes. The T-shaped long rod 327 drives the gear 326 to rotate. Since the front and rear gears 326 are meshed and connected, the front and rear T-shaped long rods 327 rotate in opposite directions. At the same time, the T-shaped long rod 327 can also drive the rotating plate 328 to rotate. The rotating plate 328 drives the long block 329 to be inserted into the long groove 3201.

[0043] There are eight T-shaped long rods 327 and then eight gears 326, and they are grouped in pairs. The T-shaped long rods 327 and the gears 326 are both arranged at the top and bottom of the rotating base 3101. The front and rear gears 326 are meshed and connected on the surface.

[0044] Furthermore, the motor 311 drives the worm 319 to rotate, and the worm 319 drives the bevel gear 315 to rotate, and the bevel gear 315 and the bevel gear 316 are engaged. At this time, the rotation of the worm 319 on the left can make the worm 319 on the right rotate in the opposite direction, which can reduce the use of multiple motors, so that one motor can drive the rotating seat 3101 that clamps the workpiece to rotate at both ends, the worm gear 312 drives the rotating shaft 3102 to rotate, and the rotating shaft 3102 drives the rotating seat 3101 to rotate, so that the clamped workpiece is driven to rotate, which is convenient for the later welding gun 54 to perform welding processing on different positions on the surface of the workpiece. Example 2

[0045] See Figure 1-8 , and on the basis of Example 1, it is further obtained that the welding protection mechanism 6 includes a rotating cylinder shaft 68, the rotating cylinder shaft 68 is rotatably connected to the left and right sides of the protection box cover 4, and the left and right sides of the protection box cover 4 are fixedly connected to the fixing rods 63, the rotating cylinder shaft 68 is arranged on the surface of the fixing rod 63, and the surface of the rotating cylinder shaft 68 is fixedly connected to the cam 67, that is, the surface of the rotating cylinder shaft 68 is fixedly connected to the handle 65, and the cam 67 is arranged between the handle 65 and the protection box cover 4, and the cam 67 is provided with a long seat 66 on the four sides away from the protection box cover 4, and a rectangular groove 62 is provided inside the long seat 66, and the upper and lower surfaces of the fixing rod 63 are fixedly connected to the mounting seat 64, and the mounting seat 64 is fixedly connected to the side of the protection box cover 4 with a mounting plate 61, the surface of the mounting plate 61 is plugged into the inside of the rectangular groove 62, and the long seat 66 and the mounting plate 61 are both threadedly connected. Two bolts 69, the protective box cover 4 is provided with a slide groove 609 on both sides, and a slider 608 is slidably connected inside the slide groove 609. The front and rear rotating cylindrical shafts 68 are fixedly connected to the side away from the protective box cover 4 with a push plate 601, and the push plate 601 is arranged on the top of the cam 67. The front and rear ends of the bottom of the push plate 601 are fixedly connected with a push block 602, and the bottom of the push block 602 is fixedly connected with a square block 603. The left and right sides of the workbench 1 are fixedly connected with a square seat 604, and the top of the square seat 604 is provided with a square groove 605. The left and right ends of the bottom of the protective box cover 4 are fixedly connected with a second T-plate 606, and the left and right sides of the top of the workbench 1 are provided with a second T-slot 607. The inside of the second T-slot 607 is slidably connected to the surface of the second T-plate 606. The top of the square groove 605 is set to be open, and the surface of the block 603 and the inside of the square groove 605 are plugged into.

[0046] Furthermore, after the protective box cover 4 drives the second T-shaped plate 606 to be inserted into the second T-shaped slot 607, the rotating handle 65 drives the rotating shaft 68 to rotate, and the rotating shaft 68 drives the cam 67 to rotate. When the raised part of the cam 67 is horizontal, it can fall under gravity, and the push plate 601 loses its support, so that the push plate 601 drives the slider 608 to slide in the slide groove 609, so that the push plate 601 drives the push block 602, and the push block 602 drives the square block 603 to be inserted into the square slot 605, and the second bolt 69 is used to thread the mounting plate 61 and the long seat 66. When the protective box cover 4 is firmly installed on the top of the workbench 1, when the workpiece is operated by the welding gun 54, the sparks generated by the welding will not fly, thereby avoiding harm to the operator. Example 3

[0047] See Figure 1-9 On the basis of Example 1, the welding mechanism 5 is further obtained to include a support plate 51, the support plate 51 is fixedly connected to the top back of the workbench 1, the front of the support plate 51 is fixedly connected to a support block 52, the front of the support block 52 is fixedly connected to a fixing ring 53, and the inner ring of the fixing ring 53 is fixedly connected to a welding gun 54.

[0048] In actual operation, when this device is used, when welding a workpiece, due to the inconsistency of the workpiece's appearance, when welding a tubular workpiece, the workpiece needs to be clamped and fixed. First, the fixing plate 324 drives the inserting plate 323 to be inserted into the slot 322, so that the fixing plate 324 drives the clamping ring 325 to clamp and fix one end of the tubular workpiece. Different clamping rings 325 are replaced according to the workpieces of different shapes or sizes.

[0049] The T-shaped long rod 327 is rotated again, so that the T-shaped long rod 327 drives the gear 326 to rotate. Since the front and rear gears 326 are meshed and connected, the front and rear T-shaped long rods 327 rotate in opposite directions. At the same time, the T-shaped long rod 327 can also drive the rotating plate 328 to rotate. The rotating plate 328 drives the long block 329 to be inserted into the long slot 3201. The long block 329 and the inserting plate 323 are screwed together by the first bolt 321. When the clamping ring 325 clamps and fixes the workpiece, the position of the clamping ring 325 will not change arbitrarily, so that the workpiece will not fall when the welding gun 54 is welding the workpiece.

[0050] When the motor 311 is started, the motor 311 drives the worm 319 to rotate, and the worm 319 drives the bevel gear 315 to rotate. The bevel gear 315 and the bevel gear 316 are engaged. At this time, the rotation of the worm 319 on the left side can cause the worm 319 on the right side to rotate in the opposite direction, which can reduce the use of multiple motors. So that one motor can drive the rotating seat 3101 that clamps the workpiece to rotate at both ends;

[0051] When the worm 319 rotates, the worm wheel 312 is driven to rotate, the worm wheel 312 drives the rotating shaft 3102 to rotate, and the rotating shaft 3102 drives the rotating seat 3101 to rotate, so that the clamped workpiece is driven to rotate, which facilitates the subsequent welding gun 54 to perform welding processing on different positions of the workpiece surface;

[0052] When the protective box cover 4 drives the second T-shaped plate 606 to be inserted into the second T-shaped slot 607, the rotating handle 65 drives the rotating shaft 68 to rotate, and the rotating shaft 68 drives the cam 67 to rotate. When the raised part of the cam 67 is horizontal, it can fall under gravity, and the push plate 601 loses its support, so that the push plate 601 drives the slider 608 to slide in the slide groove 609, so that the push plate 601 drives the push block 602, and the push block 602 drives the square block 603 to be inserted into the square slot 605. The second bolt 69 is used to thread the mounting plate 61 and the long seat 66. When the protective box cover 4 is firmly installed on the top of the workbench 1, when the workpiece is operated by the welding gun 54, the sparks generated by the welding will not fly, thereby avoiding harm to the operator.
