[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments of the present application, and all other embodiments obtained by a person of ordinary skill in the art without creative labor based on the embodiments in the present application are within the protection scope of the present application.

[0029] The following will be described in detail with reference to the drawings in the embodiments of the present application. Figures 1-6Further details of the application are provided below.

[0030] The embodiment of the application discloses a building construction welding positioning device. Figures 1-6 The building construction welding positioning device comprises a rack 10, an inner cylinder 20 and a plurality of positioning rings 21. The rack 10 is provided with an outer cylinder 30 arranged horizontally, and an inlet 31 is formed in the top of the outer cylinder 30 in the axial direction. The inner cylinder 20 is arranged inside the outer cylinder 30 and an annular gap exists between the inner cylinder 20 and the outer cylinder 30. The rack 10 is provided with a driving member 40 for driving the inner cylinder 20 to rotate intermittently, and the driving member 40 is a stepping motor. The output shaft of the driving member 40 is connected with the inner cylinder 20. The plurality of positioning rings 21 are sleeved on the outer wall of the inner cylinder 20 and located in the annular gap. A plurality of positioning grooves 211 for fixing the reinforcing steel bars are uniformly formed in the circumferential direction of the positioning ring 21. When the driving member 40 drives the inner cylinder 20 to rotate, the positioning grooves 211 on the positioning ring 21 are aligned with the inlet 31, so that the reinforcing steel bars can enter and be positioned conveniently.

[0031] The building construction welding positioning device forms a reinforcing steel bar positioning space through the annular gap between the outer cylinder 30 and the inner cylinder 20, and the positioning grooves 211 on the positioning ring 21 are periodically aligned with the inlet 31, so that the automatic positioning and loading of the reinforcing steel bars are realized. Specifically, when the inner cylinder 20 rotates, the positioning ring 21 rotates synchronously with the inner cylinder 20, so that each positioning groove 211 is accurately aligned with the inlet 31 in turn, and it is ensured that the reinforcing steel bars can enter the predetermined position smoothly. The driving member 40 adopts an intermittent driving mode, and the rotation angle of each time is matched with the distribution interval of the positioning grooves 211, so that each positioning groove 211 can stay in the predetermined position for a sufficient time, and the reinforcing steel bars can be placed accurately. The structure design not only realizes the continuous feeding of the reinforcing steel bars, but also ensures the uniform distribution of the reinforcing steel bars in the circumferential direction, and provides a stable basis for the installation and welding of the reinforcing steel ring. Meanwhile, the size of the positioning groove 211 is matched with the diameter of the reinforcing steel bar, so that the accurate positioning of the reinforcing steel bar is ensured, and the reinforcing steel bar is not excessively extruded, and the forming quality of the reinforcing steel cage is ensured.

[0032] The embodiment of the application discloses a building construction welding positioning device. Figures 2-4The tensioning mechanism 50 is arranged inside the inner cylinder 20 and is used for tensioning and fixing the annularly arranged steel bars. The tensioning mechanism 50 comprises a guide rod 51, a pushing ring 52, a hinged piece 53 and a hydraulic cylinder 54. The guide rod 51 is axially fixed in the inner cylinder 20, the pushing ring 52 is slidably sleeved on the guide rod 51, the hinged piece 53 is hingedly connected to the pushing ring 52 at one end and is provided with a radially retractable abutting block 535 at the other end. The hydraulic cylinder 54 is fixedly connected to the guide rod 51 and is connected to the pushing ring 52 at the output end. When the hydraulic cylinder 54 moves the pushing ring 52, the hinged piece 53 drives the abutting block 535 to extend and abut against the annularly arranged steel bars, so as to realize the tensioning and fixing of the steel bars. The hinged piece 53 comprises a base 531, a top seat 532, a first connecting rod 533, a second connecting rod 534 and the abutting block 535. The first connecting rod 533 is hingedly connected between the base 531 and the abutting block 535. The second connecting rod 534 is hingedly connected at one end to the top seat 532 and is hingedly connected at the other end to the middle of the two first connecting rods 533. When the pushing ring 52 moves axially, the abutting block 535 retracts radially. The hinged piece 53 is arranged in two groups in the axial direction, and the abutting blocks 535 of the two groups of hinged pieces 53 are staggered to better cooperate with the steel ring.

[0033] The abutting block 535 can be located on one side of the inner cylinder 20 close to the output end, or directly outside the output end of the inner cylinder 20, so that the position relationship between the abutting block 535 and the steel ring can be conveniently observed by the worker;

[0034] A mechanical hand 12 can also be arranged on the rack 10 to conveniently place the steel ring horizontally inside the plurality of steel bars, and rotate the steel ring so that the axis of the steel ring is consistent with the axis of the steel bars.

[0035] The tensioning mechanism 50 drives the pushing ring 52 to move along the guide rod 51 by the hydraulic cylinder 54, drives the abutting block 535 of the hinged piece 53 to radially extend, and abuts the annular steel ring outwardly to the inner wall of the steel bar. In this process, the hydraulic cylinder 54 provides stable axial thrust, and the axial movement is converted into radial expansion movement through the connecting rod mechanism of the hinged piece 53, so that the plurality of abutting blocks 535 synchronously and uniformly press the inner wall of the steel ring. The two groups of staggered hinged pieces 53 form a multi-point support structure, which ensures that the steel ring is uniformly stressed and avoids local deformation. This mechanical tensioning method not only realizes the close fitting of the steel ring and the steel bar, but also adapts to the tensioning needs of steel rings of different diameters through adjustable hydraulic pressure. Compared with manual adjustment, this mechanism has higher positioning accuracy and repeatability, effectively prevents the relative displacement of the steel bar and the steel ring caused by external force during welding, and ensures the quality and strength of the welded joint. At the same time, the cooperation of the tensioning mechanism 50 and the positioning ring 21 forms an inner and outer double positioning system, which further improves the overall structural stability of the steel cage.

[0036] In some embodiments of the present application, with reference to Figures 2-4The inner cylinder 20 is internally provided with a fixed plate 22 and an intermediate plate 23, the fixed plate 22 is provided with an internal motor 24, the output end of the internal motor 24 is connected with a threaded rod 25 parallel to the axis of the inner cylinder 20, the intermediate plate 23 is fixedly sleeved on the threaded rod 25 and a round rod 27, and a guide rod 51 is slidably arranged through the intermediate plate 23; the threaded rod 25 is threadedly sleeved with a sliding block 26, and the round rod 27 is slidably arranged through the sliding block 26; and the guide rod 51 is fixedly connected to the sliding block 26.

[0037] The inner cylinder 20 is internally provided with a fixed plate 22 and an intermediate plate 23, the fixed plate 22 is provided with an internal motor 24, the output end of the internal motor 24 is connected with a threaded rod 25 parallel to the axis of the inner cylinder 20, the intermediate plate 23 is fixedly sleeved on the threaded rod 25 and a round rod 27, and a guide rod 51 is slidably arranged through the intermediate plate 23; the threaded rod 25 is threadedly sleeved with a sliding block 26, and the round rod 27 is slidably arranged through the sliding block 26; and the guide rod 51 is fixedly connected to the sliding block 26. The inner cylinder 20 is internally provided with a fixed plate 22 and an intermediate plate 23, the fixed plate 22 is provided with an internal motor 24, the output end of the internal motor 24 is connected with a threaded rod 25 parallel to the axis of the inner cylinder 20, the intermediate plate 23 is fixedly sleeved on the threaded rod 25 and a round rod 27, and a guide rod 51 is slidably arranged through the intermediate plate 23; the threaded rod 25 is threadedly sleeved with a sliding block 26, and the round rod 27 is slidably arranged through the sliding block 26; and the guide rod 51 is fixedly connected to the sliding block 26.

[0038] In some embodiments of the present application, with reference to Figures 2-4 The hinged piece 53 comprises a base 531, a top base 532, a first connecting rod 533, a second connecting rod 534 and an abutting block 535, the first connecting rod 533 is hingedly connected between the base 531 and the abutting block 535, one end of the second connecting rod 534 is hingedly connected to the top base 532, and the other end is hingedly connected to the middle part of the two first connecting rods 533, and the abutting block 535 is radially telescopic when the pushing ring 52 moves axially.

[0039] The first connecting rod 533 and the second connecting rod 534 form a linkage mechanism that converts the axial movement of the push ring 52 into radial expansion and contraction of the abutment blocks 535. The abutment blocks 535 make multiple points of contact with the inner wall of the steel bar, ensuring even distribution of tension and preventing localized deformation. Each abutment block 535 has an abutment groove 5351 on the side wall facing the steel bar, and each abutment block 535 is equipped with positioning lugs 5352. These lugs 5352 are distributed along the circumference of the inner cylinder 20, ensuring a stable connection between the abutment blocks 535 and the steel ring.

[0040] It should be noted that two sets of hinges 53 are provided axially, and the abutment blocks 535 of the two sets of hinges 53 are staggered. This staggered distribution of the abutment blocks 535 of the two sets of hinges 53 creates multi-point staggered abutment, further increasing the contact area between the steel ring and the rebar, preventing the steel ring from tilting or shifting during tensioning, and improving the coaxiality of the rebar cage.

[0041] Some embodiments of the present invention further include a positioning member 32, which is used to further position and secure the rebar. The positioning member 32 is mounted on the outer cylinder 30. Multiple fixing seats 322 are distributed circumferentially around the outer cylinder 30, with the number of fixing seats 322 being the same as the number of positioning grooves 211 on the positioning ring 21. Abutment wheels 323 are rotatably mounted on each fixing seat 322. The outer cylinder 30 has multiple radial openings 321 that cooperate with the abutment wheels 323. When the rebar is positioned in the positioning groove 211, the abutment wheels 323 press against the outer wall of the rebar, further securing and securing the rebar.

[0042] The abutting wheel 323 presses the outer wall of the steel bar in the positioning groove 211 through the opening 321 to limit the radial runout of the steel bar; it keeps the position of the steel bar stable during the movement of the steel bar cage to prevent deviation due to vibration during welding.

[0043] In some embodiments of the present invention, reference Figures 1-6The support is provided with a conveying half ring 11 matched with the outer cylinder 30, and the reinforcing cage output from the outer cylinder 30 can be moved to the conveying half ring 11 and output; the support is also provided with a welding mechanism 60, wherein the welding mechanism 60 is used for welding the positioned reinforcing steel. The welding mechanism 60 comprises a ring-shaped guide rail 61, a sliding seat 62, a welding motor 63, a first gear 64, a gear ring 65, a pneumatic cylinder 66 and a welding gun 67. The ring-shaped guide rail 61 is fixedly installed on the rack 10, the sliding seat 62 is slidably installed on the ring-shaped guide rail 61, the welding motor 63 and the first gear 64 are arranged on the sliding seat 62, and the gear ring 65 matched with the first gear 64 is arranged on the ring-shaped guide rail 61. The pneumatic cylinder 66 and the welding gun 67 driven by the pneumatic cylinder 66 are also installed on the sliding seat 62 and are used for welding the reinforcing steel. When welding is needed, the welding motor 63 drives the first gear 64 to rotate, and through cooperation with the gear ring 65, the sliding seat 62 is driven to move along the ring-shaped guide rail 61 to the position needed to be welded. Then the pneumatic cylinder 66 drives the welding gun 67 to descend to the reinforcing steel for welding.

[0044] The worker first sends the steel ring into the feeding port 31 of the outer cylinder 30, so that the steel ring is clamped into the positioning groove 211 of the positioning ring 21 and is preliminarily aligned with the plurality of annularly arranged reinforcing steels. Then the welding mechanism 60 is started, and the first welding of the contact point of the steel ring and the reinforcing steel is performed by the welding gun 67 to form the initial fixed structure of the reinforcing cage. After the welding is completed, the internal motor 24 drives the threaded rod 25 to rotate, and drives the intermediate plate 23 and the guide rod 51 and the tensioning mechanism 50 fixedly arranged on the intermediate plate 23 to move as a whole along the inner cylinder 20 in the axial direction towards the output end. At this time, the reinforcing cage formed by the welded steel ring and reinforcing steel is simultaneously displaced towards the outlet direction of the outer cylinder 30 under the pushing of the tensioning mechanism 50, until the front end of the reinforcing cage is moved to the conveying half ring 11 at the outlet of the outer cylinder 30. In this process, the abutting wheel 323 in the positioning assembly continuously presses the outer wall of the reinforcing steel to prevent the reinforcing cage from deviating when moving. When the reinforcing cage completes a displacement, the driving part 40 controls the inner cylinder 20 to rotate again, so that the next set of positioning grooves 211 is aligned with the feeding port 31, the worker sends a new steel ring into the gap between the outer cylinder 30 and the inner cylinder 20 through the feeding mechanism 70, and embeds the new steel ring into the reinforcing steels which are not welded at present. The hydraulic cylinder 54 immediately pushes the abutting block 535 of the hinged part 53 to radially extend, and abuts the new steel ring to the inner wall of the reinforcing steel, and the welding mechanism 60 automatically circumvents along the ring-shaped guide rail 61 to complete a new round of welding. Through the circulation of the process of steel ring positioning-tensioning-welding-axial movement, the continuous automatic processing of the long-size reinforcing cage is realized, and the efficiency loss caused by manual carrying is avoided.

[0045] The welding motor 63 drives the first gear 64 to mesh with the gear ring 65, drives the sliding seat 62 to automatically move along the ring-shaped guide rail 61 in the circumferential direction of the reinforcing cage, the pneumatic cylinder 66 controls the welding gun 67 to ascend and descend, and the automatic welding of the connection point of the reinforcing steel and the steel ring is realized, and the manual intervention is reduced.

[0046] In some embodiments, referring to Figures 5-6 The feeding mechanism 70 is used to send the steel bars into the device for positioning and welding. The feeding mechanism 70 includes a feeding hopper 71 arranged at the top of the outer cylinder 30 and communicating with the feeding port 31. The outer surface of the feeding hopper 71 is provided with two feeding members 72 along the length direction thereof. Each feeding member 72 includes a feeding motor 73 and two second gears, the feeding motor 73 is electrically connected with one of the second gears, a conveying belt 74 is sleeved on the two second gears, and a plurality of pushing plates 75 are arranged on the conveying belt 74. When feeding is needed, the feeding motor 73 drives the second gears to rotate, thereby driving the conveying belt 74 and the pushing plates 75 to move, and the steel bars are pushed into the feeding port 31 from the feeding hopper 71.

[0047] The conveying belt 74 is driven by the feeding motor 73, and the pushing plates 75 continuously push the steel bars from the feeding hopper 71 to the feeding port 31 of the outer cylinder 30. The two conveying belts 74 synchronously push the steel bars to ensure that the steel bars accurately fall into the positioning groove 211, and avoid jamming or mispositioning.

[0048] The implementation principle of the building construction welding positioning device according to the embodiment of the application is as follows: the automatic positioning of the steel bars is realized through the cooperation of the outer cylinder 30 and the inner cylinder 20. After the steel bars are sent into the device by the feeding mechanism 70, the steel bars are clamped into the positioning groove 211 of the positioning ring 21, and the intermittent rotation of the inner cylinder 20 driven by the driving member 40 realizes continuous feeding. After the steel ring is placed, the hydraulic cylinder 54 pushes the abutting block 535 of the hinged member 53 to radially expand and tightly abut against the inner wall of the steel bar, and the welding mechanism 60 automatically completes the welding along the annular guide rail 61. The internal motor 24 drives the threaded rod 25 to axially move the tensioning mechanism 50, thereby pushing the completed steel bar cage to be gradually outwardly conveyed, and the abutting wheel 323 is used to press the steel bar to ensure the stability of the movement. The continuous automatic processing of the steel bar cage is realized through the circulation of the positioning-tensioning-welding-moving process.

[0049] The device realizes the full-process automation of the steel bar cage welding, significantly improves the processing efficiency, and is especially suitable for the production of long-size steel bar cages. The positioning groove 211 and the tensioning mechanism 50 ensure the accurate positioning of the steel bar and the steel ring, and avoid welding mispositioning. The axial movement mechanism realizes the continuous operation mode of welding and conveying at the same time. The multi-point fixing design ensures the stability of the steel bar cage during the processing process, and prevents deformation and deviation. The overall scheme has the advantages of high automation degree, good welding precision, high production efficiency, and can meet the demand of the building industry for batch production of steel bar cages.
