Description

Technical Field

[0001] This utility model belongs to the field of road engineering construction technology, specifically, it relates to a steel cage welding machine. Background Technology

[0002] A steel cage welding machine is an intelligent device that uses a rolling welding process to precisely assemble multiple main bars (longitudinal bars), stirrups (spiral bars), and reinforcing bars into a cage-like structure.

[0003] The prior art discloses a CNC rebar cage welding machine (CN219189086U), which includes a main body, a drive slide rail on the top of the main body, a fixed plate and a movable plate mounted on the top of the drive slide rail, a welding frame between the fixed plate and the movable plate, a drive motor on the outside of the welding frame, a camera mounted on the top of the fixed plate and the movable plate, a support platform on the top of the main body, an exhaust vent on the top surface of the main body, an exhaust fan installed inside the main body, and a junction box on the back of the main body. This CNC rebar cage welding machine utilizes the design of the exhaust fan and exhaust vent located on the bottom side of the rebar cage to blow away harmful fumes generated during welding from the bottom side upwards during processing. The design of the camera mounted on the top of the fixed plate and the movable plate allows for real-time monitoring of the welding position as it rolls to the top during processing.

[0004] Research revealed that existing technologies, in practical use, cannot dynamically adapt the welding frame to large-diameter rebar cages. When welding large-diameter rebar cages, the adapting components need to be reinstalled, which not only affects the efficiency of the welding process but also increases the workload for workers. Furthermore, since most welding frames use bolts to fix the rebars, workers need to manually tighten the bolts in stages. This not only affects the speed of fixing the rebars but also the accuracy of fixing their positions, resulting in positional deviations during the subsequent welding of the rebar cage.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

The drive motor drives the welding frame to rotate by cooperating with the transmission gear on the movable disk. A rotating seat and a bevel gear disk are rotatably mounted inside the welding frame. A fixed seat is mounted on the welding frame by bolts. The fixed seat engages with the rotating seat.

[0009] The adjustment assembly includes multiple sets arranged in a circular array on the roll welding machine frame. Each adjustment assembly includes a movable seat, a lead screw, and a bevel gear. The movable seat is movably disposed between the roll welding machine frame and the lead screw. The bevel gear disc is rotatably disposed on one side of the roll welding machine frame. The lead screw is rotatably disposed inside the roll welding machine frame. The bevel gear is fixedly disposed on one end of the lead screw. The bevel gear disc engages with the bevel gear.

[0010] A fixed assembly is movably mounted on a roll welding machine frame. The fixed assembly includes a connecting rod, a guide ring column, a turntable, a moving block, and a clamping plate. The connecting rod is hinged between the turntable and the rotating seat. The guide ring column is fixedly mounted on one side of the moving seat. The turntable is rotatably mounted between the moving seat and the guide ring column. The moving block is slidably mounted between the guide ring column and the turntable. The clamping plate is fixedly mounted on one side of the moving block.

[0011] In a preferred embodiment of this utility model, the welding frame has an inner cavity, a bevel gear disk is rotatably disposed on one side of the inner cavity, and a rotating seat is rotatably connected to the other side of the inner cavity. A rotating motor is fixedly disposed on one side of the welding frame, and the output end of the rotating motor passes through the welding frame and is connected to the bevel gear disk. Multiple bevel gears are arranged in a circumferential array inside the inner cavity, and all of the multiple bevel gears are rotatably disposed inside the inner cavity. The multiple bevel gears mesh with the same bevel gear disk.

[0012] In a preferred embodiment of this utility model, the rotating seat has a slot on the side away from the roll welding machine frame, and the fixed seat has a locking block fixedly provided on the side near the rotating seat. The locking block corresponds to the slot, and the slot engages with the locking block.

[0013] In a preferred embodiment of this utility model, the roll welding machine frame has multiple grooves arranged in a circular array, the movable seat is slidably disposed in the grooves, the lead screw is rotatably disposed in the grooves, and the movable seat is threadedly engaged with the lead screw.

[0014] In a preferred embodiment of this utility model, the guide ring column is shaped like a nail-shaped cylindrical structure, and four square holes are arranged in a circular array on the inner bottom surface of the guide ring column. The turntable is shaped like a circular plate, and four arc-shaped slides are arranged in a circular array on the turntable, with the arc-shaped slides corresponding to the square holes.

[0015] In a preferred embodiment of this utility model, the movable block consists of a cylinder and a square strip, the square strip corresponding to a square hole, the cylinder corresponding to an arc-shaped slide, the cylinder sliding within the arc-shaped slide, the square strip sliding within the square hole, and the guide ring guiding the movable block through the square hole.

[0016] In a preferred embodiment of this utility model, a clamping plate is fixedly installed on the side of the square bar away from the cylinder. The clamping plate is located at one end close to the center of the turntable. A spring damper is fixedly installed between the clamping plate and the inner curved surface of the guide ring column.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. By setting the adjustment component, the bevel gear disk synchronously drives all bevel gears and lead screws to rotate, thereby driving all corresponding moving seats to move on the roll welding machine frame. The distance between the moving seat and the center of the roll welding machine frame is the radius of the steel cage to be rolled. The setting of the adjustment component avoids the disassembly and replacement of the roll welding machine frame, which not only avoids the labor burden of replacing parts for the staff, but also improves the work efficiency of roll welding.

[0019] 2. By setting a fixed component, the rotating seat drives multiple hinged connecting rods, which in turn move the corresponding turntables around the corresponding guide rings, causing the corresponding moving blocks to drive the clamping blocks to position and clamp the reinforcing bars, thereby increasing the speed of fixing the reinforcing bars. The fixed seat fixes the rotating seat, and with the shock absorption effect of the spring damper, the clamping of the reinforcing bars is more stable during the rolling welding process, avoiding the influence of vibration on the rolling welding position, thus ensuring the accuracy of the fixing position.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0032] A type of rebar cage welding machine, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, including

[0033] A slide rail 10 has a movable disk 12 slidably mounted on its top. A support platform 11 is fixedly mounted at the top center of the slide rail 10. A welding frame 14 is rotatably mounted inside the movable disk 12. A drive motor 13 is mounted on the outside of the movable disk 12. The drive motor 13 drives the welding frame 14 to rotate by cooperating with the transmission gear on the movable disk 12. A rotating seat 16 and a bevel gear disk 21 are rotatably mounted inside the welding frame 14. A fixed seat 15 is mounted on the welding frame 14 by bolts. The fixed seat 15 is engaged with the rotating seat 16.

[0034] The adjustment assembly consists of multiple sets arranged in a circular array on the roll welding frame 14. Each adjustment assembly includes a movable seat 18, a lead screw 25, and a bevel gear 26. The movable seat 18 is movably disposed between the roll welding frame 14 and the lead screw 25. The bevel gear disk 21 is rotatably disposed on one side of the roll welding frame 14. The lead screw 25 is rotatably disposed inside the roll welding frame 14. The bevel gear 26 is fixedly disposed on one end of the lead screw 25. The bevel gear disk 21 drives the bevel gear 26.

[0035] A fixed assembly is movably mounted on the roll welding frame 14. The fixed assembly includes a connecting rod 17, a guide ring post 27, a turntable 28, a moving block 29, and a clamping plate 30. The connecting rod 17 is hinged between the turntable 28 and the rotating seat 16. The guide ring post 27 is fixedly mounted on one side of the moving seat 18. The turntable 28 is rotatably mounted between the moving seat 18 and the guide ring post 27. The moving block 29 is slidably mounted between the guide ring post 27 and the turntable 28. The clamping plate 30 is fixedly mounted on one side of the moving block 29.

[0036] Specifically, in this device, two movable discs 12 are symmetrically arranged on the slide rail 10. Each movable disc 12 contains a welding frame 14. When using this device, the distance between the two movable discs 12 is adjusted according to the length of the rebar cage. Then, multiple rebars are sequentially inserted into multiple movable seats 18 in the welding frames 14 at both ends. The ends of the rebars are fixed using corresponding fixing components. Each set of adjustment components corresponds to one fixing component. The adjustment components are adjusted according to the required diameter of the rebar cage. Then, the stirrups are wrapped around all the rebars. After completing the preparation work, the drive motor 13 is started. The drive motor 13 drives the rebars on the welding frame 14 to rotate. At this time, the operator holds a welding gun to weld the rebar cage.

[0037] It is worth noting that in this device, the welding frame 14 is installed in the middle of the movable disk 12, and the movable disk 12 is installed on the fixed disk. The fixed disk and the movable disk 12 fix the steel bars of the steel cage through the welding frame 14. The drive motor 13 is located at the bottom of the outer side of the fixed disk and the movable disk 12. The drive motor 13 drives the welding frame 14 to rotate by cooperating with the transmission gears set inside the fixed disk and the movable disk 12, which facilitates the rotational welding of the steel cage. The slide rail 10, the support table 11, the movable disk 12, the fixed disk, the drive motor 13 and the welding frame 14 are all disclosed in detail in the prior art of a CNC steel cage welding machine (CN219189086U), and will not be described in detail here.

[0038] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the roller welding frame 14 has an inner cavity 23. A bevel gear disk 21 is rotatably arranged on one side of the inner cavity 23, and a rotating seat 16 is rotatably connected to the other side of the inner cavity 23. A rotating motor 22 is fixedly arranged on one side of the roller welding frame 14. The output end of the rotating motor 22 passes through the roller welding frame 14 and is connected to the bevel gear disk 21. Multiple bevel gears 26 are arranged in a circumferential array in the inner cavity 23. All the multiple bevel gears 26 are rotatably arranged in the inner cavity 23, and the multiple bevel gears 26 mesh with the same bevel gear disk 21.

[0039] like Figure 3 and Figure 6As shown, a slot 19 is provided on the side of the rotating seat 16 away from the roll welding frame 14, and a locking block 20 is fixedly provided on the side of the fixed seat 15 close to the rotating seat 16. The locking block 20 corresponds to the slot 19, and the slot 19 engages with the locking block 20.

[0040] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the roll welding frame 14 has multiple grooves 24 arranged in a circular array. The movable seat 18 is slidably disposed in the groove 24, and the lead screw 25 is rotatably disposed in the groove 24. The movable seat 18 is threadedly engaged with the lead screw 25.

[0041] The working principle is as follows: the cross-section of the inner cavity 23 is shaped like a cross. The rotating motor 22 is fixedly installed at one end of the inner cavity 23. The rotating motor 22 drives the bevel gear disk 21 to rotate within the inner cavity 23. Multiple through holes are arranged in a circular array on the curved surface of the inner cavity 23. The inner cavity 23 communicates with the slide groove 24 through the through holes. The lead screw 25 is rotatably mounted in the through holes through bearings. Multiple bevel gears 26 and the lead screw 25 pass through the center of the inner cavity 23. The rotating bevel gear disk 21 meshes with and drives all the bevel gears 26, thereby causing the bevel gears 26 to drive the rotation of the lead screw 25. This causes the moving seat 18 to move within the slide groove 24 in coordination with the rotating lead screw 25. At the same time, a nail-shaped columnar rotating seat is rotatably connected to the other end face of the inner cavity 23. 16. The curved side of the rotating seat 16 is hinged with multiple connecting rods 17. The number of connecting rods 17 corresponds to the number of moving seats 18. When the moving seat 18 moves, the connecting rods 17, in conjunction with the moving hinges of the moving seat 18, drive the rotating seat 16 to rotate. Then, when using the fixing component to clamp the steel bar, the rotating seat 16 is rotated again. The rotation of the rotating seat 16 drives the hinges of the multiple connecting rods 17 to deflect, thereby clamping the steel bar by rotating the fixing component. Afterwards, the fixing seat 15 is bolted to the side wall of the welding machine frame 14. The welding machine frame 14 uses the fixing seat 15 to engage and limit the rotating seat 16. The fixing seat 15 uses the locking slot 19 and the locking block 20 to prevent the rotating seat 16 from rotating.

[0042] like Figure 5 , Figure 7 and Figure 8 As shown, the guide ring post 27 is shaped like a nail-shaped cylindrical mechanism. The bottom surface of the guide ring post 27 has four square holes arranged in a circular array. The turntable 28 is shaped like a circular plate. The turntable 28 has four arc-shaped slides arranged in a circular array, and the arc-shaped slides correspond to the square holes.

[0043] like Figure 5 and Figure 8 As shown, the movable block 29 consists of a cylinder and a square bar. The square bar corresponds to a square hole, and the cylinder corresponds to an arc-shaped slide. The cylinder slides in the arc-shaped slide, and the square bar slides in the square hole. The guide ring 27 guides the movable block 29 through the square hole.

[0044] like Figure 8 As shown, a clamping plate 30 is fixedly installed on the side of the square bar away from the cylinder. The clamping plate 30 is located at one end close to the center of the turntable 28. A spring damper 31 is fixedly installed between the clamping plate 30 and the inner curved surface of the guide ring column 27. The clamping plate 30 is elastically connected to the guide ring column 27 through the spring damper 31.

[0045] The working principle is as follows: A through hole is provided on the part of the movable seat 18 away from the lead screw 25. This through hole is used for the steel bar to pass through. When the rotating seat 16 is rotated, multiple connecting rods 17 on the rotating seat 16 will be deflected. When the connecting rods 17 are in an inclined state, the turntable 28, which is hinged to the connecting rods 17, rotates around the wall of the guide ring column 27. At this time, under the shape limitation and guiding effect of the square hole, the cylinder of the movable block 29 is pushed along the rotation of the arc-shaped slide on the turntable 28. The pushed cylinder then drives the square bar to slide within the square hole. At this time, the movable block 29... 9. The guide ring column 27 has the ability to achieve circumferential expansion and contraction. Each guide ring column 27 is equipped with four sets of moving blocks 29, four clamping plates 30 and four spring dampers 31 arranged in a circumferential array. The four moving blocks 29 simultaneously drive their respective clamping plates 30 to clamp and fix the steel bars in the through hole. When the steel cage is rolled and welded, the steel bars are kept stable by the fixation of the four clamping plates 30. At the same time, the slight vibration of the steel bars during the rolling and welding process can be transmitted to the clamping plates 30 and then reduced by the spring dampers 31 between the clamping plates 30 and the guide ring column 27.

[0046] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
