[0029] The left propulsion mechanism includes a left housing 3 slidably arranged on the bottom plate 1, a slider 19 is arranged at the bottom of the left housing 3, and a slide rail 18 matching the slider 19 is arranged on the bottom plate 1. Side plates 20 are arranged on both sides of the left housing 3, and locking bolts 21 matching the bottom plate 1 are threadedly connected on the side plates 20. A partition 5 is provided inside the left housing 3. A first driving gear 6 is rotatably mounted above the partition 5 and a first motor 7 driving the first driving gear 6 is installed below the partition 5. The first driving gear 6 is meshed with a first driven gear 8. The first driven gear 8 is connected to a first clamping roller 9 via a connecting shaft. The first driving gear 6 is also meshed with an auxiliary gear 10. The auxiliary gear 10 is meshed with a second driven gear 11. The second driven gear 11 is connected to a second clamping roller 12 via a connecting shaft. Two groups of the first clamping roller 9 and the second clamping roller 12 are provided. The first clamping roller 9 and the second clamping roller 12 are symmetrically arranged. Anti-skid pads are provided on the outside of the first clamping roller 9 and the second clamping roller 12. The first driven gear 8, the auxiliary gear 10 and the second driven gear 11 are all rotatably connected to the partition 5.

[0030] The right propulsion mechanism includes a right housing 4 disposed on the base 2, the base 2 and the bottom plate 1 are integrally formed, the internal structure of the right housing 4 is symmetrical with the internal structure of the left housing 3, a rotating shaft 13 is disposed between the right housing 4 and the left housing 3 and the rotating shaft 13 is fixed in the base 2, and the right housing 4 is rotatably connected to the rotating shaft 13 through a connecting ring 14; a half gear 15 is disposed outside the connecting ring 14. The left propulsion mechanism and the right propulsion mechanism drive the first clamping roller 9 and the second clamping roller 12 through the first motor 7 to transfer the parts to be welded on both sides to the center for docking.

[0031] The driving mechanism is used to drive the right housing 4 to rotate around the rotating shaft 13 ; the driving mechanism includes a second motor 17 mounted on the base 2 , the output shaft of the second motor 17 is connected to a second driving gear 16 , and the second driving gear 16 is meshed with the half gear 15 .

[0032] The power supply and control module 22 controls the first motor 7 and the driving mechanism.

[0033] Working principle of this embodiment: When using the welding fixture for manufacturing mechanical equipment, first, tighten the locking bolt 21 so that the left propulsion mechanism is limited on the bottom plate 1;

[0034] like Figure 1 As shown, when the left propulsion mechanism and the right propulsion mechanism are used in parallel, the accessories to be welded on both sides are clamped between the first clamping roller 9 and the second clamping roller 12, and the first motors 7 on both sides are controlled to run in reverse, the first motor 7 drives the first driving gear 6 to rotate, the first driving gear 6 drives the first driven gear 8 and the auxiliary gear 10 to rotate, the first driven gear 8 drives the first clamping roller 9 to rotate, the auxiliary gear 10 drives the second driven gear 11 to rotate, and the second driven gear 11 drives the second clamping roller 12 to rotate, thereby driving the accessories to be welded on both sides to be transferred to the center for docking. After docking, the first motors 7 on both sides are controlled to stop running and welding can be carried out.

[0035] like Figure 3 , Figure 4 As shown, when welding at an inclined angle is required, first, the second motor 17 is controlled to start, the second motor 17 drives the second driving gear 16 to rotate, the second driving gear 16 drives the half gear 15 to drive the connecting ring 14 and the right propulsion mechanism to rotate, and stops after rotating to the required inclination angle, and then the first motors 7 on both sides are controlled to run in the opposite direction, and the welding accessories to be connected are connected according to the steps for parallel use as mentioned above. After docking, the first motors 7 on both sides are controlled to stop running, and welding can be carried out.

[0036] After welding is completed, remove the locking bolt 21, hold the welding accessory, and start the first motor 7 on the left side alone, so that the left propulsion mechanism slides to the left on the base plate 1, thereby disengaging the welding accessory from the left propulsion mechanism, and then start the first motor 7 on the right side alone, so that the welding accessory disengages from the right propulsion mechanism, and is successfully removed.
