At this time, the radiation tube sleeve 16 is blocked by the limiting stopper 202. The first air cylinder 203 is started, the first air cylinder 203 pushes the horizontal bar 206 to move upwards, the horizontal bar 206 drives the radiation tube sleeve 16 placed on the upper surface thereof to move upwards. When the radiation tube sleeve 16 exceeds the limiting stopper 202, the radiation tube sleeve 16 rolls into the bottom of the feeding bar 204. Then, the first air cylinder 203 is retracted and reset, and the radiation tube sleeve 16 falls to the upper surface of the roller 503;

[0097] The above structure and process please refer to Figures 1-3 .

[0098] The first rodless air cylinder 401 is started, the first rodless air cylinder 401 drives the first supporting plate 402 to move towards one end close to the radiation tube sleeve 16 through the first three-axis air cylinder 404, the first supporting plate 402 drives the jaw mechanism 403 to move towards one end close to the radiation tube sleeve 16, and the jaw mechanism 403 is inserted into the inside of the radiation tube sleeve 16;

[0099] The third air cylinder 4031 is started, the third air cylinder 4031 pushes the movable seat 4033 to move towards the inside of the radiation tube sleeve 16, the movable seat 4033 drives the clamping plate 4035 to move outward through the first swing lever 4034 and the second swing lever 4036, and the clamping plate 4035 clamps the radiation tube sleeve 16 from the inner wall of the radiation tube sleeve 16. The first rodless air cylinder 401 is started, the first rodless air cylinder 401 drives the radiation tube sleeve 16 to move into the welding chamber 8 through the jaw mechanism 403, that is, the radiation tube sleeve 16 sequentially passes through the first feeding hole 6011, the second feeding hole 801, and the rotary support 905, so that the radiation tube sleeve 16 is placed on one side of the welding gun 11, thereby completing the automatic feeding of the radiation tube sleeve 16;

[0100] The above structure and process please refer to Figures 6-7 .

[0101] Meanwhile, in the initial state, the three-jaw chuck 704 is located outside the welding chamber 8. The connecting flange 17 to be welded is sleeved onto the outer clamping plate 7041 of the three-jaw chuck 704 by an external robotic arm, and the limiting baffle 7042 contacts the back of the connecting flange 17. The three-jaw chuck 704 is activated, which drives the outer clamping plate 7041 to move outward.

The second rodless cylinder 701 is activated, which drives the connecting flange 17 to move into the interior of the welding chamber 8 through the three-jaw chuck 704. The fourth cylinder 703 is activated, which pushes the three-jaw chuck 704 to move closer to the end of the radiant tube sleeve 16, so that the connecting flange 17 contacts the radiant tube sleeve 16, thereby completing the automatic feeding of the connecting flange 17.

[0102] Please refer to the above structure and process. Figures 13-14 .

[0103] Meanwhile, after the pushing mechanism 4 pushes the radiant tube sleeve 16 into the welding chamber 8, the gripper mechanism 403 retracts and resets to release the grip on the radiant tube sleeve 16. At this time, the first motor 609 starts and drives the first output shaft 6010 to rotate. The first output shaft 6010 drives the gear to rotate. The gear meshes with the teeth at the outer ring 602, causing the outer ring 602 to rotate. The outer ring 602 drives the connecting column 603 to move. The connecting column 603 pushes the positioning strip 606 towards the radiant tube sleeve 16 through the connecting rod 604 and the connecting piece 605. The three positioning strips 606 act synchronously on the radiant tube sleeve 16 to position it, so that the center of the radiant tube sleeve 16 is aligned with the center of the connecting flange 17, avoiding welding misalignment caused by misalignment of the centers when welding the radiant tube sleeve 16 and the connecting flange 17.

[0104] Please refer to the above structure and process. Figures 9-12 .

[0105] Start the swing cylinder 1001. The swing cylinder 1001 drives the welding gun 11 to rotate through the first slide cylinder 1002 and the second slide cylinder 1003.

[0106] Please refer to the above structure and process. Figures 19-20 .

[0107] Argon gas, an inert gas, is introduced into the welding chamber 8 through the gas pipe 14. Argon gas can protect the weld bead from oxidation during the welding process. The arc welding machine 12 is started to weld the weld between the welding torch 11 and the radiant tube sleeve 16 through the welding torch 11.

[0108] Please refer to the above structure and process. Figure 13 .

[0109] The second motor 901 is started, and the second motor 901 drives the second output shaft 904 to rotate through the three-axis reducer 902. The second output shaft 904 drives the inner ring of the slewing bearing 905 to rotate through the gear. The slewing bearing 905 drives the adjusting mechanism 10 to rotate in a circle through the mounting bracket 906. The adjusting mechanism 10 drives the welding torch 11 to rotate in a circle. The rotary encoder 903 is connected to the output end of the three-axis reducer 902. The rotary encoder 903 detects the speed and number of rotations of the gear on the second output shaft 904. Based on the gear ratio between the gear on the second output shaft 904 and the inner ring of the slewing bearing 905, the speed and angle of rotation of the inner ring of the slewing bearing 905 are detected, thereby controlling the rotation angle of the welding torch 11 so that the rotation range of the welding torch 11 is kept between 0-360°. At this time, the welding torch 11 rotates one revolution along the weld seam of the radiant tube sleeve 16 and the connecting flange 17 to complete the circumferential weld seam. At the same time, the radiant tube sleeve 16 and the connecting flange 17 are fixed during welding.

[0111] After welding, the rotating mechanism 9 drives the adjusting mechanism 10 to move in the opposite direction and reset. The second slide cylinder 1003 drives the welding torch 11 to retract and reset. The three-jaw chuck 704 drives the outer clamping plate 7041 to retract and reset. The outer clamping plate 7041 releases the fixation to the connecting flange 17. The positioning strip 606 in the positioning and centering mechanism 6 retracts and resets, releasing the fixation to the radiant tube sleeve 16 through the positioning strip 606. The radiant tube sleeve 16 is then fixed and clamped by the jaw mechanism 403. Roller 503 supports the radiant tube sleeve 16. Since the second feed hole 801 and the first feed hole 6011 are much larger than the diameter of the connecting flange 17, the first rodless cylinder 401 is activated. The first rodless cylinder 401 drives the gripper mechanism 403 to retract and reset. The gripper mechanism 403 pulls the welded radiant tube sleeve 16 out of the welding chamber 8. The radiant tube sleeve 16 and the connecting flange 17 move to the outside of the welding chamber 8. Then the gripper mechanism 403 and the first rodless cylinder 401 retract and reset.

[0112] Please refer to 1-19 for the above structure and process.

[0113] The first cylinder 203 is activated, which drives the feeding bar 204 to move upward via the crossbar 206. The feeding bar 204 lifts the radiant tube sleeve 16 on the upper surface of the roller 503. At this time, the crossbar 206 does not exceed the height of the limit stop bar 202. The second cylinder 303 is activated, which drives the rack 305 to retract via the connecting bar 304. The rack 305 meshes with the rotating shaft 306, which drives the external gear 307 to rotate. The external gear 307 drives the limit plate 205 to rotate 90 degrees, and the limit plate 205 releases the restriction on the radiant tube sleeve 16. At this time, the radiant tube sleeve 16 located on the upper surface of the feeding bar 204 rolls into the upper surface of the unloading rack 301, thus completing the automatic unloading.
