DETAILED DESCRIPTION

[0051] For the purpose of understanding the present application, the following will be described in conjunction with the accompanying drawings and examples.

[0052] Reference Figures 1 to 3 It can be seen that the present application discloses a single-double-wound-rib welding head, comprising a head main body 1, a moving sliding table 2 and a welding gun assembly 3; wherein the front end of the head main body 1 is provided with a tracking wheel set 6 for tracking the wound rib; wherein the tracking wheel set 6 comprises a tracking wheel body 61, the surface of the tracking wheel body 61 is formed with a first clamping groove 62 adapted to single-wound-rib and a second clamping groove 63 adapted to double-wound-rib (the first clamping groove 62 and the second clamping groove 63 are arranged in left and right relationship), the back of the head main body 1 is angularly adjustable mounted on the welding main body structure through an angle offset disc support mechanism or adopts the connecting structure between the mechanical arm and the fuselage in the application number 2021104672402 for adjusting the inclination supporting angle of the head main body 1, the moving sliding table 2 is integrally installed on the head main body 1 and can be floated and telescoped forward and backward, the front end of the moving sliding table 2 is telescopically installed or swingably installed with a main rib tracking clamping jaw 4 for tracking and pressing the main rib, the welding gun assembly 3 is connected to the moving sliding table 2 and can move synchronously with the moving sliding table 2 (telescoping forward and backward, sliding up and down).

[0053] Further, as Figures 6-14As shown, the movable slide 2 includes a mounting plate 21, a floating cylinder 22, a connecting block 23, and a telescopic cylinder 24. The mounting plate 21 is mounted vertically and slidably on the machine head body 1. The connecting block is provided on the side of the mounting plate 21 facing the main rib tracking claw 4. The floating cylinder 22 controls the forward and backward extension and retraction of the connecting block. The telescopic cylinder 24 is also mounted on the connecting block. The extended end of the telescopic cylinder 24 is connected to the main rib tracking claw 4, which slides on the connecting block or presses against the main rib tracking claw 4, which is swingably connected to the connecting block. Furthermore, the floating cylinder 22 is mounted on the side of the mounting plate 21 facing away from the main rib tracking claw 4. A guide shaft 26 is also mounted on the mounting plate 21 via a linear bearing 25. One end of the guide shaft 26 is connected to the extended end of the floating cylinder 22, and the other end of the guide shaft 26 passes through the mounting plate 21 and is connected to the connecting block. Specifically, (1) one end of the guide shaft 26 is connected to the protruding end of the floating cylinder 22 through a connecting plate 27; (2) it includes two parallel guide shafts 26, which are respectively arranged on the upper and lower sides of the floating cylinder 22 to ensure the stability of the guide during extension and retraction.

[0054] Example 1:

[0055] like Figures 6-12 As shown, the extended end of the telescopic cylinder 24 is connected to the main rib tracking claw 4 which is slidably mounted on the connecting block.

[0056] Specifically, the top of the connecting block 23 forms a slot (running horizontally from front to back) adapted for the main-rebar tracking jaw 4, into which one end of the main-rebar tracking jaw 4 slides. Furthermore, the connecting block 23 includes a connecting block 28, to which the extended end of the telescopic cylinder 24 is connected. This block 28 has a positioning notch for positioning the main-rebar tracking jaw 4. During the welding tracking process, the main-rebar tracking jaw 4 retracts and retracts under the action of the telescopic cylinder 24, achieving reliable tracking and pressure against the main rebar.

[0057] Example 2:

[0058] like Figures 13-15 As shown, the extended end of the telescopic cylinder 24 presses against the main rib tracking claw 4 which is swingably connected to the connecting block.

[0059] Specifically, the extension end of the telescopic cylinder 24 is connected with a pressing block 29 for pressing against the main reinforcement tracking claw 4, one end of the main reinforcement tracking claw 4 is rotatably (hingedly) connected to the top of the connecting block, and the top of the connecting block is formed with a limiting portion 231 for abutting against the main reinforcement tracking claw 4, the main reinforcement tracking claw 4 is abutted against the limiting portion 231 after swinging (rotating) a certain angle under the action of the pressing block 29, and the main reinforcement tracking claw 4 is horizontally arranged after swinging into position. In actual use, the extension of the telescopic cylinder 24 is controlled to realize the extension of the main reinforcement tracking claw 4 (corresponding to the horizontal arrangement position), until the tracking of the main reinforcement is completed, when tracking to the topmost end, the telescopic cylinder 24 is retracted, and the main reinforcement tracking claw 4 swings reversely under the action of the main reinforcement; when tracking to the topmost end, if the telescopic cylinder 24 cannot be retracted, as the reinforcement cage continues to rotate, the force (reverse swinging force) acting on the main reinforcement tracking claw 4 becomes larger and larger, and the force acts reversely on the extension end of the telescopic cylinder 24, so that the telescopic cylinder 24 is passively compressed. Compared with the structure of the first embodiment, the swinging structure can avoid the damage of the mechanism when the telescopic cylinder 24 fails, has high reliability, and prolongs the service life.

[0060] Further, the pressing block 29 and the connecting block can be connected by a sliding connection structure to improve the stability of the telescopic pressing block 29.

[0061] It should be noted that the main reinforcement tracking claw 4 in the second embodiment is in a horizontal state under the action of the telescopic cylinder 24 before being pressed against the main reinforcement, and after the main reinforcement tracking claw 4 is tracked and pressed against the main reinforcement, as the reinforcement cage rotates, there is a displacement between the lower edge of the main reinforcement tracking claw 4 and the main reinforcement in the front-rear direction, and the length of the lower edge of the main reinforcement tracking claw 4 is used to track and press against the main reinforcement.

[0062] As shown in Figure 21 The present application also includes a lifting slide 5 arranged on the machine head body 1, the lifting slide 5 includes a linear rail 51 arranged vertically on the machine head body 1, a lifting slide plate 52 sliding on the linear rail 51, and a lifting cylinder 53, the lifting cylinder 53 is installed on the bottom of the machine head body 1, the telescopic end of the lifting cylinder 53 is connected to the lifting slide plate 52, and the mounting plate 21 is connected to the lifting slide plate 52. The lifting cylinder 53 is used to realize the vertical sliding of the moving slide 2 and the welding gun assembly 3, so as to cooperate with the main reinforcement tracking claw 4 to realize the tracking operation of the main reinforcement; specifically, when the main reinforcement tracking claw 4 is pressed against the upper surface of the main reinforcement, the reinforcement cage rotates counterclockwise, as the reinforcement cage rotates, the lifting cylinder 53 extends to control the moving slide 2 and the welding gun assembly 3 to move upward, when the main reinforcement tracking claw 4 moves to the highest position, the telescopic cylinder 24 is retracted, the lifting slide plate 52 slides downward under the action of the lifting cylinder 53, and then the moving slide 2 and the welding gun assembly 3 are reset, and the welding gun 39 is used to realize welding at the intersection position of the main reinforcement and the reinforcement during the upward movement.

[0063] In the present application, the welding gun assembly 3 comprises a base plate 31 connected to the moving slide 2 and a positioning plate 32 horizontally and left-right slidably relative to the base plate 31 and positioned on the base plate 31 by a locking assembly after sliding into position, and the welding gun 39 is installed on the positioning plate 32.

[0064] Further, the base plate 31 is formed with horizontally and left-right arranged guide sliding grooves 311, the guide sliding grooves 311 are slidably installed with guide members 33 connected to the positioning plate 32, the base plate 31 is provided with multiple positioning holes 312 arranged in a horizontal and left-right direction, and the locking assembly comprises spring pins 34 connected to the positioning plate 32 and used for locking in the positioning holes 312. Among them, the base plate 31 is arranged with multiple rows of horizontally arranged positioning holes 312 in a rectangular array, the locking assembly comprises multiple spring pins 34 adapted to the multiple rows of positioning holes 312, and the multiple spring pins 34 are arranged in a staggered manner in the horizontal and left-right direction. In the present embodiment, (1) the guide members 33 and the guide sliding grooves 311 are arranged to play a guiding sliding role, ensuring the stability of the left-right horizontal sliding of the base plate 31 (welding gun 39); (2) the base plate 31 is formed with multiple guide sliding grooves 311 arranged in parallel; (3) by arranging multiple spring pins 34 arranged in a staggered manner, the adjustment distance of the base plate 31 can be reduced to adapt to the adjustment of the short distance position (horizontal and left-right direction) of welding; for example, the distance between adjacent positioning holes 312 in the same row is N, when there is only one row of positioning holes 312 and one spring pin 34, the minimum adjustment distance of the welding gun 39 is N; on the contrary, when there are n rows of positioning holes 312 and corresponding n spring pins 34, the minimum adjustment distance of the welding gun 39 is N / n, so it can be seen that the multiple spring pins 34 arranged in a staggered manner can reduce the adjustment distance and realize distance fine adjustment; (4) the guide members 33 can be guide screws screwed to the positioning plate 32.

[0065] Specifically, as Figures 22-23As shown, the spring pin 34 comprises a threaded sleeve 341, a compression spring 342, and a positioning rod 343. The first end of the threaded sleeve 341 is internally formed with a first abutting portion for abutting the compression spring 342. The first end of the positioning rod 343 is exposed to the first end of the threaded sleeve 341. The second end of the positioning rod 343 passes through and is exposed to the second end of the threaded sleeve 341. The second end of the positioning rod 343 is formed with a second abutting portion. The compression spring 342 is sleeved on the positioning rod 343 and is abutted between the first and second abutting portions. The welding gun assembly 3 further comprises a cover plate 7 fixed to the positioning plate 32. The cover plate 7 is formed with a threaded hole for screwing the threaded sleeve 341. The positioning plate 32 is formed with a through hole corresponding to the positioning hole 312. Wherein: (1) when the spring pin 34 is aligned with the through hole and the positioning hole 312, the second end of the positioning rod 343 passes through the through hole and is positioned in the positioning hole 312 under the resetting force of the compression spring 342, so as to realize the positioning between the positioning plate 32 and the bottom plate 31 after the sliding to position; (2) when the spring pin 34 is misaligned with the through hole and the positioning hole 312, the second end of the positioning rod 343 is abutted on the upper surface of the positioning plate 32, and the compression spring 342 is in a further compressed state; (3) the cross section of the cover plate 7 is in the shape of n, i.e. the inside of the cover plate 7 can be hollowly arranged; (4) the first end of the positioning rod 343 is further fixed with a handle 344 exposed to the threaded sleeve 341, so as to facilitate the outward pulling of the handle 344 to realize the disengagement of the positioning rod 343 from the positioning hole 312 and the through hole. As can be seen, during the adjustment of the welding gun assembly 3, the positioning rod 343 is first disengaged from the positioning hole 312 and the through hole by pulling the spring pin 34 upward, and then the positioning plate 32 (welding gun 39) is moved in the horizontal direction. After being moved to position, the spring pin 34 is released, and the positioning rod 343 is abutted in the positioning hole 312 at the corresponding position under the resetting force of the compression spring 342, thereby completing the positioning after the sliding to position.

[0066] Further, the positioning plate 32 is fixed with a welding gun 39 positioning assembly. The welding gun 39 positioning assembly comprises a lower positioning block 352 fixed to the positioning plate 32 and an upper positioning block 351 detachably connected to the lower positioning block 352. A clamping space for clamping the welding gun 39 is formed between the lower positioning block 352 and the upper positioning block 351. Specifically, the clamping space comprises a lower positioning groove formed on the lower positioning block 352 and an upper positioning groove formed on the upper positioning block 351.

[0067] Further, the front end of the welding gun assembly 3 is rotatably installed with a horizontal tracking roller 36 for closely abutting the winding rib. The horizontal tracking roller 36 is drivingly connected with an encoder 38 through a transmission belt 37. In actual use, the welding gun assembly 3 and the moving slide table 2 are controlled to move forward as a whole by the floating cylinder 22 until the horizontal tracking roller 36 is abutted on the surface of the winding rib, so as to realize the tracking of the winding rib. The rotation speed of the winding rib is obtained by the encoder 38.

[0068] In the present application, the main reinforcement tracking claw 4 comprises a claw body 41 and a claw mouth 42 detachably mounted at the bottom end of the front part of the claw body 41, which is used to adapt to different specifications of the main reinforcement. Specifically, the lower edge of the claw mouth 42 is used to press against the main reinforcement. When the diameter specification of the main reinforcement is larger, the claw mouth 42 with a smaller height is replaced, and when the diameter specification of the main reinforcement is smaller, the claw mouth 42 with a larger height is replaced. That is, when the diameter of the main reinforcement of the reinforcement cage changes, by selecting different specifications of the claw mouth 42, the tracking and pressing against the main reinforcement with different diameter specifications at the same height position can be realized. Specifically, the extension end of the telescopic air cylinder 24 is connected with or pressed against the claw body 41.

[0069] In the present application, a protective shell is mounted outside the moving slide table 2, and the protective shell is connected to the mounting plate 21.
