Existing welding auxiliary equipment includes a clamping assembly and a welding assembly. The clamping assembly includes a sleeve mounted on a sliding seat for positioning the steel bar. Several radially movable positioning rods are threaded onto the sleeve's body. The welded end of the steel bar is pre-cut using a cutting device to form a groove. The steel bar is then passed through the sleeve, and the positioning rods are used to press the bar together, aligning the axis of the sleeve with the steel bar. The sleeve is then moved to the rated position, and a drive mechanism drives the sleeve to rotate, cooperating with the welding assembly to weld the joint between the two steel bars.

Figure 7 One end of the guide rod 9 is fixedly connected to the limit plate 8, and the other end of the guide rod 9 is fixedly connected to the positioning rod 10. A number of guide plates 11 are provided on the outside of the supporting arc plate 3. The number of guide plates 11 matches the number of guide rods 9. The guide plate 11 is provided with a guide groove 12. The guide groove 12 is inclined in the axial direction of the supporting arc plate 3, that is, the two ends of the guide groove 12 are at different distances from the axis of the supporting arc plate 3. The guide plate 11 can move axially relative to the supporting arc plate 3, and the positioning rod 10 is slidably sleeved with the guide groove 12.

[0023] A fixing seat 17 is fixedly provided at the midpoint position of the top of the support platform 1, and a connecting shaft 6 is rotatably sleeved on one side of the fixing seat 17. The connecting shaft 6 includes a connecting part 601, and the connecting part 601 is rotatably sleeved on the fixing seat 17. Both ends of the connecting shaft 6 are set as transmission parts 602, and a flat key is provided on the transmission part 602. The flat key can also be set as a spline. The transmission part 602 is slidingly sleeved with the corresponding No. 2 screw 16, that is, the transmission part 602 moves axially relative to the No. 2 screw 16 and drives the No. 2 screw 16 to rotate through the flat key transmission. A driving motor 18 is fixedly connected to one side of the bottom of the fixing seat 17, and the output end of the driving motor 18 is transmission-connected to the No. 2 gear 19. One end of the connecting part 601 is fixedly sleeved with the No. 3 gear 20, and the No. 2 gear 19 and the No. 3 gear 20 are meshed with each other.

[0024] When in use, the steel bar at one end with the end pre-cut to form a groove is placed from the top of the support arc plate 3 to the inner side of the support arc plate 3. After the two steel bars are placed, the drive motor 18 is started, and the drive motor 18 drives the No. 2 gear 19 to rotate, the No. 2 gear 19 drives the No. 3 gear 20 to rotate, the No. 3 gear 20 drives the connecting shaft 6 to rotate, the transmission part 602 of the connecting shaft 6 drives the No. 2 screw 16 to rotate, the No. 2 screw 16 drives the connecting rod 15 to move axially, and the connecting rod 15 drives the guide plate 11 to move relative to the support arc plate 3.

[0025] The corresponding positions of the guide groove 12 and the positioning rod 10 change, and the guide plate 11 moves horizontally relative to the positioning rod 10. The inner wall of the guide groove 12 presses against the positioning rod 10 to drive the positioning rod 10 to move close to the supporting arc plate 3. The positioning rod 10 drives the guide rod 9 to move, and the guide rod 9 drives the limit plate 8 to move radially relative to the supporting arc plate 3, so that several limit plates 8 that move equal distances cooperate to clamp the steel bars, and the axis of the steel bars is collinear with the axis of the supporting arc plate 3, that is, the axis of the steel bars placed on both sides is collinear, so as to ensure the subsequent docking accuracy.

[0026] A positioning mechanism 7 is provided on one side of the sliding seat 2. The positioning mechanisms 7 corresponding to the two sliding seats 2 are arranged in a horizontal staggered manner. Figure 3The positioning mechanism 7 includes a fixed plate 701, one side of the fixed plate 701 is slidably connected to a positioning plate 702, the positioning plate 702 is in an inverted L shape, one side of the fixed plate 701 is rotatably clamped with a No. 1 screw 703, the No. 1 screw 703 is threadedly sleeved with the positioning plate 702, and one end of the No. 1 screw 703 is fixedly sleeved with a No. 1 gear 704. Two fixed racks 37 are fixedly provided on the top of the support platform 1, and the fixed racks 37 are arranged along the axial direction of the support arc plate 3, and the fixed racks 37 are meshed with the corresponding No. 1 gears 704.

[0027] The plate body part at the top of the positioning plate 702 corresponds to the axial position of the supporting arc plate 3. When the steel bars are placed on the supporting arc plate 3, the processed end of the steel bars is pressed against the plate body of the positioning plate 702, and then the drive motor 18 is started to fix the distance that the end of the steel bars protrudes from the supporting arc plate 3, thereby ensuring the accuracy of the subsequent docking position.

[0028] After the rebar is positioned, the electric push rod 38 drives the corresponding sliding seat 2 to slide horizontally the rated distance. The sliding seat 2 drives the fixed plate 701 to move. The fixed plate 701 drives the No. 1 screw 703 to move, thereby driving the No. 1 gear 704 to move relative to the fixed rack 37. The fixed rack 37 drives the No. 1 gear 704 to rotate relative to the fixed plate 701. The No. 1 gear 704 drives the No. 1 screw 703 to rotate. The No. 1 screw 703 is arranged horizontally in the radial direction of the support arc plate 3. The rotation of the No. 1 screw 703 drives the positioning plate 702 to move horizontally relative to the sliding seat 2, moving away from the end of the rebar. The sliding seat 2 moves to the end of the two rebars to align. This pre-positioning ensures the docking position accuracy, facilitating subsequent auxiliary welding operations. During the movement of the sliding seat 2, the sliding seat 2 drives the No. 2 screw 16 to move relative to the transmission part 602. When the sliding seat 2 retreats and resets, the fixed rack 37 drives the positioning plate 702 to reset, thereby completing the automatic contraction and extension of the positioning mechanism 7, thereby improving the convenience of using the welding auxiliary equipment.

[0029] One end of the connecting rod 15 is fixedly connected to the limiting sleeve 14, which is arc-shaped. One side of the limiting sleeve 14 is rotatably sleeved with a connecting arc plate 13. The limiting sleeve 14 can drive the connecting arc plate 13 to move axially. At the same time, the connecting arc plate 13 can rotate around the axis of the supporting arc plate 3 without separating from the limiting sleeve 14. The connecting arc plate 13 is fixedly connected to the guide plate 11. A welding mechanism 4 is provided on one side of the fixed seat 17. A notched gear 29 with a notch on the top of the supporting arc plate 3 is fixedly sleeved. The notched gear 29 is used to drive the supporting arc plate 3 to rotate. A transmission shaft 5 is rotatably provided at the bottom of the fixed seat 17. The transmission shaft 5 is connected to the guide plate 11. The notched gear 29 is connected for transmission. Specifically, flat keys are provided on both sides of the transmission shaft 5. The flat key shaft can also be set as a spline shaft. A sixth gear 27 is rotatably provided on one side of the sliding seat 2. The sixth gear 27 is connected to the transmission shaft 5 through a flat key transmission. That is, the sixth gear 27 can move axially relative to the transmission shaft 5. At the same time, the transmission shaft 5 can drive the sixth gear 27 to rotate. Two seventh gears 28 are rotatably provided on one side of the sliding seat 2. The seventh gear 28 and the corresponding sixth gear 27 are engaged with each other. The seventh gear 28 can mesh with the notched gear 29. At least one seventh gear 28 remains engaged with the notched gear 29.

[0030] After the steel bars are butt-jointed, the drive shaft 5 is driven to rotate, and the drive shaft 5 drives the No. 6 gear 27 to rotate, and the No. 6 gear 27 drives the two No. 7 gears 28 to rotate, and the No. 7 gear 28 cooperates to drive the notch gear 29 to rotate, and the notch gear 29 drives the support arc plate 3 to rotate, and the support arc plate 3 cooperates with the guide rod 9 and the limit plate 8 to drive the steel bars to rotate, thereby adjusting the circumferential corresponding position of the steel bars and the welding mechanism 4, so as to adjust the joint position to complete the butt welding of the steel bars while ensuring that the distance between the welding mechanism 4 and the steel bars remains unchanged, thereby ensuring the quality of the welding. After the welding is completed, the drive motor 18 is activated, and the transmission drives the limit plate 8 to loosen the clamping of the steel bars, and the steel bars can be taken out from the notch of the support arc plate 3, further improving the convenience of using the auxiliary welding equipment.

[0031] Example 2, as Figure 1-Figure 2 and Figure 4-Figure 7 On the basis of Example 1, a rotating ring 21 with an open top is rotatably provided on one side of the fixed seat 17. The axis of the rotating ring 21 is collinear with the axis of the supporting arc plate 3. The welding mechanism 4 is set as a welding gun. One end of the rotating ring 21 is fixedly connected to a rotating seat 22. The welding mechanism 4 can drive the rotating seat 22 to rotate. A notched tooth ring 24 is fixedly connected to one side of the rotating ring 21. A fourth gear 25 is rotatably provided on one side of the bottom of the fixed seat 17. A fifth gear 26 is fixedly sleeved on the shaft body of the transmission shaft 5 at the midpoint position. The fifth gear 26 and the notched gear 29 are both engaged with the fourth gear 25.

[0032] During welding, the welding mechanism 4 is manually manipulated to move, the welding mechanism 4 drives the rotating seat 22 to rotate, the rotating seat 22 drives the notched gear ring 24 to rotate, the notched gear ring 24 drives the fourth gear 25 to rotate, the fourth gear 25 drives the fifth gear 26 to rotate, the fifth gear 26 drives the transmission shaft 5 to rotate, the transmission shaft 5 cooperates with the sixth gear 27, the seventh gear 28, and the notched gear 29 to drive the support arc plate 3 to rotate, and the direction of rotation of the support arc plate 3 is opposite to the direction of rotation of the welding mechanism 4.

[0033] Therefore, after the welding mechanism 4 and the supporting arc plate 3 rotate to the rated angle relative to the fixing seat 17, the welding mechanism 4 rotates one circle relative to the supporting arc plate 3, so that while the welding mechanism 4 maintains the distance from the supporting arc plate 3, it can manually perform spot welding, continuous welding and other welding actions on the groove size of the steel bar end. Multiple spot welding actions can be performed on the part with large groove to ensure full butt welding of the steel bars, ensure welding quality and improve welding flexibility. The welding process does not require manual flipping of the steel bars, further improving the convenience of the welding process. After welding is completed, the welding mechanism 4 is reset and the supporting arc plate 3 is reset.

[0034] Example 3, as Figure 1-Figure 2 and Figure 4-Figure 7 An adjustment seat 23 is slidingly provided on one side of the rotating seat 22. The adjustment seat 23 can move in the radial direction of the rotating ring 21 without separating from the rotating seat 22. The adjustment seat 23 is fixedly connected to the welding mechanism 4. The middle position of the connecting shaft 6 is provided with a threaded portion 603. The outer thread of the threaded portion 603 is threadedly sleeved with a movable plate 30. The outer side of the movable plate 30 is fixedly connected with an inner arc plate 31. The inner arc plate 31 is slidably connected to the fixed seat 17. The fixed seat 17 limits the relative rotation of the inner arc plate 31. The outer side of the inner arc plate 31 is rotatably sleeved with an outer arc plate 32. Both the inner arc plate 31 and the outer arc plate 32 are provided with openings to avoid affecting the removal of the steel bar after welding is completed.

[0035] When the inner arc plate 31 drives the outer arc plate 32 to move axially, the outer arc plate 32 can rotate relative to the inner arc plate 31 without separating from the inner arc plate 31. One end of the outer arc plate 32 is fixedly connected to a connecting plate 33, and the connecting plate 33 is L-shaped. One side of the connecting plate 33 is slidably sleeved with the rotating seat 22, and one side of the connecting plate 33 is fixedly connected to an adjustment plate 34. The plate body of the adjustment plate 34 is provided with an adjustment groove 35. One end of the bottom of the adjustment seat 23 is fixedly connected to an adjustment rod 36, and the adjustment rod 36 is slidably sleeved in the adjustment groove 35. The adjustment groove 35 is inclined in the radial direction of the rotating ring 21, that is, the distances between the two sides of the adjustment groove 35 and the axis of the rotating ring 21 are not equal.

[0036] When centering and clamping the steel bars, the threaded portion 603 of the connecting shaft 6 rotates to drive the movable plate 30 to move horizontally. The movement of the movable plate 30 drives the inner arc plate 31 to move. The inner arc plate 31 drives the outer arc plate 32 to move, thereby driving the connecting plate 33 to move axially in the rotating ring 21 relative to the rotating seat 22. The connecting plate 33 drives the adjusting plate 34 to move relative to the adjusting rod 36, so that the corresponding positions of the adjusting slot 35 and the adjusting rod 36 change.

[0037] The adjusting rod 36 drives the adjusting seat 23 to move radially relative to the rotating seat 22 in the rotating ring 21, thereby adjusting the distance from the welding mechanism 4 to the axis of the rotating ring 21. When the diameter of the steel bar is smaller, the connecting shaft 6 rotates more times to drive the limit plate 8 to move a greater distance to clamp the steel bar. The driving motor 18 determines whether the clamping is in place based on the torque value of the servo feedback. At this time, the welding mechanism 4 moves a corresponding distance, so that the axial distance from the welding mechanism 4 to the supporting arc plate 3 is adapted to the diameter of the steel bar, further improving the applicability of the auxiliary welding equipment.
