A welding auxiliary equipment for steel reinforcement in building construction

Abstract

This application relates to the field of rebar welding equipment technology, and discloses an auxiliary welding device for rebar components in building construction, including a support platform. Sliding seats are slidably arranged on both sides of the top of the support platform. A welding mechanism is arranged on one side of the fixed seat. A supporting arc plate is arranged on the inner side of the sliding seats, and a notch is opened at the top of the supporting arc plate. This invention provides horizontal positioning of the rebar when it is placed on the supporting arc plate using a positioning plate, and uses a limiting plate to center and clamp the rebar. The sliding seats move to remove the rebar after clamping, improving convenience while ensuring the accuracy of subsequent rebar connection positions. In this case, the welding mechanism rotates and, in conjunction with a gear set and drive shaft, drives the supporting arc plate to rotate in the opposite direction. This allows the worker to operate only the welding mechanism, ensuring that the rebar rotates relative to the welding mechanism while maintaining the rated welding spacing, thus guaranteeing the welding quality of this semi-automatic welding equipment.

Description

TECHNICAL FIELD

[0001] The application relates to the technical field of reinforcing bar welding equipment, in particular to a reinforcing bar welding auxiliary equipment for house building construction. BACKGROUND

[0002] In the construction process of a house building, two reinforcing bars need to be welded and connected by a welding auxiliary equipment to form a reinforcing bar component that meets the construction requirements. The existing welding auxiliary equipment comprises a clamping assembly and a welding assembly. The clamping assembly comprises a sleeve arranged on a sliding seat and used for positioning the reinforcing bars. A plurality of positioning rods capable of moving radially are threadedly sleeved on the sleeve body. The welding end of the reinforcing bar is pre-cut to form a groove by a cutting device. Then the reinforcing bar is inserted through the sleeve. The positioning rods are used to press the reinforcing bar so that the reinforcing bar is coaxial with the axis of the sleeve. Then the sleeve is moved to a rated position. The sleeve is driven to rotate by a driving mechanism. The welding assembly is used to weld the joint of the two reinforcing bars.

[0003] However, in the process of using the existing welding auxiliary equipment, the reinforcing bars are manually inserted through the sleeve. The distance between the ends of the two reinforcing bars to the sleeve is different. The sliding seat needs to be manually moved to butt joint the two reinforcing bars. The butt joint position of the reinforcing bars is prone to error and deviates from the welding position of the welding assembly, resulting in a decrease in welding quality. Moreover, the reinforcing bar welded and completed needs to be pulled out from the sleeve on one side after the positioning is released, which leads to a decrease in overall processing efficiency.

[0017] This application provides an auxiliary welding device for steel reinforcement in building construction. A drive motor rotates a connecting shaft, allowing the shaft to move a guide plate without affecting the horizontal movement of the sliding seat or the rotation of the supporting arc plate. This adjusts the radial position of the guide rod, centering and clamping the steel reinforcement placed inside the supporting arc plate. A positioning plate, in conjunction with the positioning seat, positions the steel reinforcement horizontally. As the positioning plate moves with the sliding seat, a first gear engages with a fixed rack to rotate a first screw, driving the positioning plate away from the end of the steel reinforcement. This improves the convenience of the welding process and ensures that the position of the subsequent steel reinforcement after butt welding corresponds to the position of the welding mechanism, enabling semi-automatic welding of the steel reinforcement and guaranteeing welding quality. Furthermore, the steel reinforcement is removed and placed from the notch in the supporting arc plate, further enhancing the convenience of the welding operation.

[0018] This application provides an auxiliary welding device for steel reinforcement in building construction. The device uses a manually oscillating welding mechanism to rotate the joint of the butt-welded steel reinforcement. This allows for manual welding based on the size of the bevel cut at the end of the steel reinforcement. During the oscillation of the welding mechanism, a rotating ring, drive shaft, and transmission gear set drive a supporting arc plate to rotate in opposite directions. This ensures that after the welding mechanism rotates to a rated angle, the supporting arc plate rotates one full revolution relative to the welding mechanism, completing the welding of the entire joint. This eliminates the need for separate adjustment of the supporting arc plate, improving welding efficiency. Furthermore, the welding mechanism rotates around the axis of the steel reinforcement, ensuring that the distance between the welding mechanism and the steel reinforcement remains at a rated distance during rotation, further improving welding quality.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, as Figures 1-7 A welding auxiliary device for steel reinforcement in building construction includes a support platform 1. Sliding seats 2 are slidably arranged on both sides of the top of the support platform 1. Electric push rods 38 for driving the sliding seats 2 to slide horizontally are fixedly arranged on both sides of the top of the support platform 1. The output end of the electric push rods 38 is fixedly connected to the sliding seats 2. A support arc plate 3 is rotatably arranged on the inner side of the sliding seats 2. The top of the support arc plate 3 has a notch. The support arc plate 3 can rotate relative to the sliding seats 2 without disengaging from the sliding seats 2. The axis of the support arc plate 3 is horizontal.

[0030] The supporting arc plate 3 is slidably fitted with several guide rods 9, which are arranged in a ring. The guide rods 9 can support the arc plate 3 to slide in the radial direction. (See reference...) Figure 7 One end of the guide rod 9 is fixedly connected to the limiting plate 8, and the other end of the guide rod 9 is fixedly connected to the positioning rod 10. Several guide plates 11 are provided on the outer side of the supporting arc plate 3. The number of guide plates 11 is matched with 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. The positioning rod 10 is slidably sleeved with the guide groove 12.

[0031] A connecting rod 15 is slidably sleeved on one side of the sliding seat 2. The connecting rod 15 can slide relative to the sliding seat 2 in the axial direction of the supporting arc plate 3. The connecting rod 15 is T-shaped and is used to drive the guide plate 11 to move axially. A second screw 16 is rotatably engaged on one side of the bottom of the sliding seat 2. The second screw 16 can rotate relative to the sliding seat 2. The second screw 16 is an externally threaded rod and is threadedly sleeved with the connecting rod 15.

[0032] A fixed base 17 is fixedly installed at the midpoint of the top of the support platform 1. A connecting shaft 6 is rotatably sleeved on one side of the fixed base 17. The connecting shaft 6 includes a connecting part 601, which is rotatably sleeved with the fixed base 17. Both ends of the connecting shaft 6 are configured as transmission parts 602. A flat key is provided on the transmission part 602. The flat key can also be configured as a spline. The transmission part 602 is slidably sleeved with the corresponding second screw 16. That is, while the transmission part 602 moves axially relative to the second screw 16, it drives the second screw 16 to rotate through the flat key. A drive motor 18 is fixedly connected to one side of the bottom of the fixed base 17. A second gear 19 is drivenly connected to the output end of the drive motor 18. A third gear 20 is fixedly sleeved on one end of the connecting part 601. The second gear 19 and the third gear 20 mesh with each other.

[0033] In use, the steel bar with a pre-cut bevel is placed from the top of the supporting arc plate 3 to the inside of the supporting arc plate 3. After both steel bars are placed, the drive motor 18 is started. The drive motor 18 drives the second gear 19 to rotate, the second gear 19 drives the third gear 20 to rotate, the third gear 20 drives the connecting shaft 6 to rotate, the transmission part 602 of the connecting shaft 6 drives the second screw 16 to rotate, the second 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 supporting arc plate 3.

[0034] When the corresponding position of the guide groove 12 and the positioning rod 10 changes, the guide plate 11 moves horizontally relative to the positioning rod 10. The inner wall of the guide groove 12 abuts against the positioning rod 10, causing the positioning rod 10 to move closer to the supporting arc plate 3. The positioning rod 10 causes the guide rod 9 to move, and the guide rod 9 causes the limiting plate 8 to move radially relative to the supporting arc plate 3. This allows several limiting plates 8 that have moved equidistantly to cooperate in clamping the reinforcing bars. The axis of the reinforcing bars is collinear with the axis of the supporting arc plate 3, that is, the axes of the reinforcing bars placed on both sides are collinear, ensuring the subsequent docking accuracy.

[0035] 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 horizontally in a staggered manner. (See reference) Figure 3The positioning mechanism 7 includes a fixed plate 701, a positioning plate 702 slidably connected to one side of the fixed plate 701, the positioning plate 702 being inverted L-shaped, a first screw 703 being rotatably engaged on one side of the fixed plate 701, the first screw 703 being threadedly connected to the positioning plate 702, and a first gear 704 being fixedly sleeved at one end of the first screw 703. Two fixed racks 37 are fixedly installed on the top of the support platform 1, the fixed racks 37 being arranged along the axial direction of the support arc plate 3, and the fixed racks 37 meshing with the corresponding first gear 704.

[0036] The top part of the positioning plate 702 corresponds to the axis of the supporting arc plate 3. When the steel bar is placed on the supporting arc plate 3, the processed end of the steel bar is pressed against the plate body of the positioning plate 702, and then the drive motor 18 is started to fix the distance of the end of the steel bar protruding from the supporting arc plate 3, so as to ensure the accuracy of the subsequent docking position.

[0037] After the rebar is positioned, the electric push rod 38 drives the corresponding sliding seat 2 to slide horizontally a rated distance. The sliding seat 2 drives the fixed plate 701 to move, and the fixed plate 701 drives the first screw 703 to move, thereby driving the first gear 704 to move relative to the fixed rack 37. The fixed rack 37 drives the first gear 704 to rotate relative to the fixed plate 701. The first gear 704 drives the first screw 703 to rotate. The first screw 703 is arranged horizontally in the radial direction of the supporting arc plate 3. The rotation of the first 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 point where the ends of the two rebars are in contact. Through pre-positioning, the accuracy of the docking position is ensured, which facilitates subsequent auxiliary welding operations.

[0038] During the movement of the sliding seat 2, the sliding seat 2 drives the second screw 16 to move relative to the transmission part 602. When the sliding seat 2 retracts and resets, the fixed rack 37 drives the positioning plate 702 to reset, thereby completing the automatic retraction and extension reset of the positioning mechanism 7, improving the ease of use of the welding auxiliary equipment.

[0039] One end of the connecting rod 15 is fixedly connected to a limiting sleeve 14, which is arc-shaped. A connecting arc plate 13 is rotatably sleeved on one side of the limiting sleeve 14. While the limiting sleeve 14 can drive the connecting arc plate 13 to move axially, the connecting arc plate 13 can rotate around the axis of the supporting arc plate 3 without disengaging 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 at the top is fixedly sleeved on one side of the supporting arc plate 3. The notched gear 29 is used to drive the supporting arc plate 3 to rotate. A drive shaft 5 is rotatably provided at the bottom of the fixed seat 17. The drive shaft 5 is connected to... The notched gear 29 is connected by a transmission mechanism. Specifically, both sides of the transmission shaft 5 are provided with flat keys, which can also be configured as spline shafts. A sixth gear 27 is rotatably mounted on one side of the sliding seat 2. The sixth gear 27 is connected to the transmission shaft 5 via a flat key, meaning that the sixth gear 27 can move axially relative to the transmission shaft 5 while the transmission shaft 5 can drive the sixth gear 27 to rotate. Two seventh gears 28 are rotatably mounted on one side of the sliding seat 2. The seventh gear 28 meshes with the corresponding sixth gear 27. The seventh gear 28 can also mesh with the notched gear 29, ensuring that at least one seventh gear 28 remains meshed with the notched gear 29.

[0040] After the rebar is joined, the drive shaft 5 rotates, which in turn drives the sixth gear 27 to rotate. The sixth gear 27 then drives two seventh gears 28 to rotate, which in turn drives the notched gear 29 to rotate. The notched gear 29 then drives the supporting arc plate 3 to rotate. The supporting arc plate 3, in conjunction with the guide rod 9 and the limiting plate 8, drives the rebar to rotate, thereby adjusting the circumferential position of the rebar and the welding mechanism 4. This allows the joint position to be adjusted to complete the butt welding of the rebar while ensuring that the distance between the welding mechanism 4 and the rebar remains unchanged, thus ensuring the quality of the welding. After the welding is completed, the drive motor 18 is activated, which drives the limiting plate 8 to release the clamp on the rebar. The rebar can then be removed from the notch of the supporting arc plate 3, further improving the ease of use of this auxiliary welding equipment.

[0041] Example 2, as Figures 1-2 and Figures 4-7 Based on Embodiment 1, a rotating ring 21 with an opening at the top is rotatably provided on one side of the fixed base 17. The axis of the rotating ring 21 is collinear with the axis of the supporting arc plate 3. The welding mechanism 4 is a welding torch. A rotating seat 22 is fixedly connected to one end of the rotating ring 21. The welding mechanism 4 can drive the rotating seat 22 to rotate. A notched gear 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 base 17. A fifth gear 26 is fixedly sleeved at the midpoint of the shaft of the transmission shaft 5. The fifth gear 26 and the notched gear 29 are both meshed with the fourth gear 25.

[0042] During welding, the welding mechanism 4 is manually operated 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, and the transmission shaft 5, together with the sixth gear 27, the seventh gear 28, and the notched gear 29, drives the support arc plate 3 to rotate. The direction of rotation of the support arc plate 3 is opposite to the direction of rotation of the welding mechanism 4.

[0043] This allows the welding mechanism 4 and the supporting arc plate 3 to rotate at a rated angle relative to the fixed seat 17. After the welding mechanism 4 rotates one full turn relative to the supporting arc plate 3, while maintaining the distance between the welding mechanism 4 and the supporting arc plate 3, manual welding actions such as spot welding and continuous welding can be performed on the bevel size of the end of the steel bar. Multiple spot welding actions can be performed on the large bevel section to ensure full butt welding of the steel bar, ensuring welding quality and improving welding flexibility. The welding process does not require manual flipping of the steel bar, further improving the convenience of the welding process. After the welding is completed, the welding mechanism 4 and the supporting arc plate 3 are reset.

[0044] Example 3, as Figures 1-2 and Figures 4-7 An adjusting seat 23 is slidably provided on one side of the rotating seat 22. The adjusting seat 23 can move in the radial direction of the rotating ring 21 without disengaging from the rotating seat 22. The adjusting seat 23 is fixedly connected to the welding mechanism 4. A threaded part 603 is provided at the middle position of the connecting shaft 6. A moving plate 30 is threadedly sleeved on the outer side of the threaded part 603. An inner arc plate 31 is fixedly connected to the outer side of the moving plate 30. The inner arc plate 31 is slidably connected to the fixed seat 17. The fixed seat 17 restricts the relative rotation of the inner arc plate 31. An outer arc plate 32 is rotatably sleeved on the outer side of the inner arc plate 31. Both the inner arc plate 31 and the outer arc plate 32 have openings to avoid affecting the removal of the steel bars after welding.

[0045] While 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 detaching from the inner arc plate 31. A connecting plate 33 is fixedly connected to one end of the outer arc plate 32. The connecting plate 33 is L-shaped. One side of the connecting plate 33 is slidably sleeved with the rotating seat 22. An adjusting plate 34 is fixedly connected to one side of the connecting plate 33. An adjusting groove 35 is provided on the body of the adjusting plate 34. An adjusting rod 36 is fixedly connected to one end of the bottom of the adjusting seat 23. The adjusting rod 36 is slidably sleeved in the adjusting groove 35. The adjusting groove 35 is inclined in the radial direction of the rotating ring 21, that is, the distances from the axis of the rotating ring 21 to the two sides of the adjusting groove 35 are not equal.

[0046] When clamping the reinforcing bar, the threaded part 603 of the connecting shaft 6 rotates, causing the moving plate 30 to move horizontally. The movement of the moving plate 30 causes the inner arc plate 31 to move, and the inner arc plate 31 causes the outer arc plate 32 to move. This causes the connecting plate 33 to move axially upward relative to the rotating seat 22 in the rotating ring 21. The connecting plate 33 causes the adjusting plate 34 to move relative to the adjusting rod 36, thereby changing the corresponding position of the adjusting groove 35 and the adjusting rod 36.

[0047] The adjusting rod 36 drives the adjusting seat 23 to move radially relative to the rotating seat 22 on the rotating ring 21, thereby adjusting the distance between the welding mechanism 4 and 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 limiting plate 8 to move more distance to clamp the steel bar. The drive motor 18 judges the clamping position according to the torque value fed back by the servo. At this time, the welding mechanism 4 moves a corresponding distance, so that the axial distance between the welding mechanism 4 and the supporting arc plate 3 is adapted to the diameter of the steel bar, further improving the applicability of the auxiliary welding equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
