Description

Technical Field

[0001] This utility model relates to the field of spiral ground pile welding technology, and more specifically, to an automatic welding equipment for nuts used in the production of spiral ground piles. Background Technology

[0002] The automatic nut welding device is an automated equipment integrating mechanical positioning, automatic feeding, and precision welding. It is widely used in the automotive, hardware, and home appliance industries to achieve efficient welding of nuts to sheet metal. The core of the device includes a feeding mechanism, positioning fixtures, a welding system, and a control system. The feeding mechanism delivers nuts systematically via a vibratory feeder or robotic arm. The positioning fixtures are pneumatically or servo-driven to ensure precise alignment. The welding system primarily employs resistance welding and laser welding technologies, and parameters can be matched according to the workpiece material. The control system supports parameter presets and fault alarms; some models include visual inspection capabilities. Compared to manual welding, its welding efficiency is increased by more than 30%, ensuring weld consistency, reducing the risk of incomplete or missing welds, and is suitable for mass production and standardized manufacturing.

[0003] For automated welding of nuts on small instruments, different positions on the instrument can be welded by moving the welding device or the small instrument. For larger instruments, due to the difficulty in moving the instrument, the welding device is usually moved around the instrument. However, helical ground piles are large in size and weight, and the welding points may be located at multiple positions on the side of the pile. When the automated welding device is working, it is difficult for the operator to easily adjust the position of the helical ground pile. Helical ground piles are usually laid flat in the factory, and it is also difficult for the welding device to select different angles around the ground pile.

[0004] Therefore, this utility model provides an automatic welding equipment for nuts in the production of helical ground piles to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an automatic welding equipment for nuts used in the production of helical piles, which has the advantage of automatically adjusting the welding position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding equipment for nuts used in the production of helical ground piles, comprising an automatic welding mechanism, a conveying mechanism disposed below the automatic welding mechanism, and an adjustment mechanism for adjusting the position and direction of the helical ground pile disposed between the two conveying mechanisms. The adjustment mechanism comprises a housing, a processing channel formed on the housing for the helical ground pile to pass through, semi-circular clamps symmetrically disposed within the housing for fixing the helical ground pile, and semi-circular bases symmetrically disposed around the semi-circular clamps. The semi-circular clamps and the semi-circular bases have semi-circular cross-sections, and the semi-circular bases are rotatably disposed at both ends of the semi-circular clamps. A driving mechanism for driving the adjustment mechanism is disposed within the housing.

[0007] As a preferred technical solution of this utility model, a protrusion with a T-shaped cross section is fixedly provided on the outer wall of the semicircular clamping plate corresponding to the range of the semicircular base, and a groove is provided on the semicircular base to fit the rotation of the protrusion.

[0008] As a preferred technical solution of this utility model, a sawtooth A is provided on the semicircular clamp plate corresponding to the semicircular base. The driving mechanism includes a rotating shaft disposed inside the housing corresponding to one side of the semicircular clamp plate, a rotating cylinder fixedly disposed on the rotating shaft, and a sawtooth B disposed on the side wall of the rotating cylinder. The range of the sawtooth B corresponds to the sawtooth A, and the sawtooth A meshes with the sawtooth B.

[0009] As a preferred technical solution of this utility model, the outer shell has movable grooves on two sides perpendicular to the conveying direction. The movable grooves on both sides of the outer shell extend horizontally and are correspondingly positioned. The two ends of the rotating shaft are movably disposed in the movable grooves. A servo motor A is slidably disposed on the outer shell along the extension direction of the movable grooves. One end of the rotating shaft passes through the movable grooves and is fixedly connected to the output end of the servo motor A.

[0010] As a preferred technical solution of this utility model, the rotating shaft is rotatably connected to both ends of the rotating cylinder, and the sleeve is fixedly connected to the outer wall of the semi-circular base.

[0011] As a preferred technical solution of this utility model, movable seats are symmetrically arranged inside the outer shell corresponding to the upper and lower ends of the semi-circular base. The two ends of the movable seats are respectively fixed on the semi-circular bases at the two ends of the corresponding semi-circular clamping plates. Threaded rods are arranged at the upper and lower ends of the semi-circular bases, passing through the movable seats in sequence. The threaded rods are threadedly connected to the movable seats, and the threads at both ends of the threaded rods are opposite. A servo motor B is fixedly arranged on the outer wall of the outer shell. One end of the threaded rod passes through the outer shell and is fixedly connected to the output end of the servo motor B.

[0012] As a preferred embodiment of this utility model, there are at least two threaded rods located at the upper and lower ends of the semicircular base.

[0013] As a preferred embodiment of the present invention, the conveying mechanism includes a conveyor belt and support members arranged in an array along the extension direction of the conveyor belt. The conveyor belt is fixedly connected to the support members, and the top end of the support members is aligned with the curvature of the outer wall of the spiral pile.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting an adjustment mechanism, places the spiral ground pile on the support on the conveyor belt in the conveying mechanism. The support drives the spiral ground pile to move towards the welding mechanism and the adjustment mechanism. The welding nut moves to the position of the welding mechanism. The pile body passes through the adjustment mechanism and drives the servo motor B in the drive mechanism. The servo motor B drives the threaded rod at the output end to rotate. The threaded rod drives the threaded moving seat to move synchronously towards the center. The moving seat drives the semi-circular base in the adjustment mechanism. The semi-circular base drives the semi-circular clamping plate. The semi-circular clamping plates move closer to each other and clamp the spiral ground pile. Rubber pads or other tools that increase friction and provide cushioning can be fixed between the semi-circular clamping plates. The rotation of the semi-circular clamping plate can adjust the position and direction of the spiral ground pile.

[0016] 2. This utility model uses a sleeve to move the semi-circular base, which in turn moves the sleeve. The sleeve moves the rotating shaft, which in turn moves the rotating cylinder and servo motor A synchronously. At this time, the rotating shaft moves in the movable groove, and the servo motor A slides on the outer shell. The saw teeth B and A always remain in a meshing state. When the servo motor A is turned, the servo motor A drives the rotating shaft to rotate, which in turn drives the rotating cylinder to rotate. The rotating cylinder, through the meshing of the saw teeth B and A, drives the semi-circular clamp to rotate in the semi-circular base, thereby driving the spiral ground pile to rotate.

[0017] 3. This utility model, by setting up a conveyor belt, ensures the stability of the spiral pile during transport by aligning the top of the support components on the conveyor belt with the curvature of the outer wall of the spiral pile. Furthermore, the gaps between the support components provide a placement space for the welded nuts, preventing direct contact between the nuts and the conveyor belt and thus avoiding damage. The automatic nut welding process may occur before or after the welding of the spiral plate on the side of the spiral pile. If it occurs after the welding process, the support components and spiral plates can be manufactured as a set, with the spacing between the support components equal to or a multiple of the pitch of the spiral plate. This ensures that the side of the spiral plate closest to the conveyor belt is positioned between the support components, guaranteeing normal transport. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides an automatic welding equipment for nuts used in the production of helical ground piles, including an automatic welding mechanism 1. A conveying mechanism 2 is arranged below the automatic welding mechanism 1. An adjustment mechanism 3 for adjusting the position and direction of the helical ground pile is arranged between the two conveying mechanisms 2. The adjustment mechanism 3 includes a housing 31, a processing channel 311 opened on the housing 31 for the helical ground pile to pass through, semi-circular clamping plates 32 symmetrically arranged inside the housing 31 for fixing the helical ground pile, and semi-circular bases 33 symmetrically arranged around the semi-circular clamping plates 32. The semi-circular clamping plates 32 and the semi-circular bases 33 have semi-circular cross sections. The semi-circular bases 33 are rotatably arranged at both ends of the semi-circular clamping plates 32. A driving mechanism 4 for driving the adjustment mechanism 3 is arranged inside the housing 31.

[0026] Specifically, the spiral pile is placed on the conveying mechanism 2. The support 22 drives the spiral pile to move towards the welding mechanism 1 and the adjusting mechanism 3. The welding nut moves to the position of the welding mechanism 1. The pile body passes through the adjusting mechanism 3. The driving mechanism 4 drives the semi-circular base 33. The semi-circular base 33 drives the semi-circular clamping plate 32. The semi-circular clamping plates 32 move closer to each other and clamp the spiral pile. Rubber pads or other tools that increase friction and provide cushioning can be fixed between the semi-circular clamping plates 32. The driving mechanism 4 drives the semi-circular clamping plate 32 to rotate, which can drive the spiral pile to adjust its direction to cooperate with the nut welding.

[0027] Furthermore, a protrusion 34 with a T-shaped cross section is fixedly provided on the outer wall of the semicircular clamp 32 corresponding to the range of the semicircular base 33, and a groove 331 is provided on the semicircular base 33 to fit the rotation of the protrusion 34.

[0028] Specifically, the semicircular base 33 maintains the rotation of the semicircular clamp 32 on the semicircular base 33 through the groove 331 thereon. During the rotation, the semicircular clamp 32 will move to the semicircular base 33 on the symmetrical side. When the rotation is 180 degrees, the semicircular clamp 32 will exchange positions. When the semicircular clamp 32 is separated, the semicircular clamp 32 can be moved to the semicircular base 33 on their respective sides first.

[0029] It is worth noting that a serration A321 is provided on the semicircular clamping plate 32 corresponding to the semicircular base 33. The driving mechanism 4 includes a rotating shaft 41 disposed inside the housing 31 corresponding to one side of the semicircular clamping plate 32, a rotating cylinder 42 fixedly disposed on the rotating shaft 41, and a serration B421 disposed on the side wall of the rotating cylinder 42. The range of the serration B421 corresponds to the serration A321, and the serration A321 meshes with the serration B421.

[0030] Specifically, the rotation of the rotating shaft 41 drives the rotating cylinder 42 to rotate. The rotating cylinder 42 drives the semi-circular clamp 32 to rotate within the semi-circular base 33 through the meshing of the saw teeth B421 and A321, thereby driving the spiral pile to rotate and adjust its position.

[0031] It should be noted that the outer casing 31 has movable slots 312 on two sides perpendicular to the conveying direction. These movable slots 312 extend horizontally and are correspondingly positioned on both sides of the outer casing 31. The two ends of the rotating shaft 41 are movably disposed within the movable slots 312. A servo motor A43 is slidably mounted on the outer casing 31 along the extension direction of the movable slots 312. One end of the rotating shaft 41 passes through the movable slots 312 and is fixedly connected to the output end of the servo motor A43. The servo motor A43 drives the rotating shaft 41 to rotate. The movable slots 312 provide space for the rotating shaft 41 to move horizontally, thus maintaining synchronization with the semi-circular base 33.

[0032] Furthermore, sleeves 44 are rotatably connected to both ends of the rotating shaft 41 corresponding to the rotating cylinder 42, and the sleeves 44 are fixedly connected to the outer wall of the semi-circular base 33. When the semi-circular base 33 moves, it drives the sleeves 44, which in turn drives the rotating shaft 41. The rotating shaft 41 then drives the rotating cylinder 42 and the servo motor A43 to move synchronously.

[0033] Furthermore, within the outer casing 31, symmetrically arranged movable seats 45 are provided at the upper and lower ends corresponding to the semicircular base 33. The two ends of the movable seats 45 are respectively fixed to the semicircular base 33 at the two ends of the corresponding semicircular clamp 32. The upper and lower ends of the semicircular base 33 are respectively provided with threaded rods 46 that pass through the movable seats 45 in sequence. The threaded rods 46 are threadedly connected to the movable seats 45, and the threads at both ends of the threaded rods 46 are opposite. A servo motor B47 is fixedly arranged on the outer wall of the outer casing 31. One end of the threaded rod 46 passes through the outer casing 31 and is fixedly connected to the output end of the servo motor B47.

[0034] Specifically, the servo motor B47 is operated, which drives the threaded rod 46 at the output end to rotate. The threaded rod 46 drives the threaded movable seat 45 to move synchronously towards the center. The movable seat 45 drives the semi-circular base 33, which drives the semi-circular clamping plate 32. The semi-circular clamping plates 32 move closer to each other and clamp the helical ground pile.

[0035] Furthermore, there are at least two threaded rods 46 located at the upper and lower ends of the semi-circular base 33, which can maintain the stability of the movable seat 45.

[0036] Furthermore, the conveying mechanism 2 includes a conveyor belt 21 and support members 22 arranged in an array along the extension direction of the conveyor belt 21. The conveyor belt 21 is fixedly connected to the support members 22, and the top end of the support members 22 is in line with the curvature of the outer wall of the spiral pile.

[0037] Specifically, the top of the support member 22 on the conveyor belt 21 matches the curvature of the outer wall of the spiral pile, stabilizing the spiral pile during conveying. The gaps between the support members 22 provide a placement position for the welded nuts, preventing direct contact between the nuts and the conveyor belt 21 and thus avoiding damage. The automatic nut welding process may occur before or after the welding of the spiral plate on the side of the spiral pile. If it occurs after the welding process, the support members 22 and the spiral plate can be manufactured as a set, with the spacing between the support members 22 equal to or a multiple of the pitch of the spiral plate. This ensures that the spiral plate, on the side closest to the conveyor belt 21, is positioned between the support members 22, guaranteeing normal transport.

[0038] Working principle and usage process of this utility model:

[0039] Used to describe the instructions for use or operation of the technology;

[0040] This automatic nut welding equipment is used in the factory processing stage of helical piles. The helical pile is placed on a support 22 on the conveyor belt 21 in the conveying mechanism 2. The support 22 moves the helical pile towards the welding mechanism 1 and the adjusting mechanism 3. The welding nut position moves to the welding mechanism 1. The pile body passes through the adjusting mechanism 3, which activates the servo motor B47 in the drive mechanism 4. The servo motor B47 drives the threaded rod 46 at the output end to rotate. The threaded rod 46 drives the threaded connecting moving seat 45 to move synchronously towards the center. The moving seat 45 drives the semi-circular base 33, which in turn drives the semi-circular clamping plates 32. The semi-circular clamping plates 32 move closer together and clamp the helical pile. Rubber pads or other tools to increase friction and provide cushioning can be fixed between the semi-circular clamping plates 32. Simultaneously, the semi-circular base 33 moves, driving the sleeve 44. The sleeve 44 drives the rotating shaft 41, which in turn drives the rotating cylinder 42 and the servo motor A43 to move synchronously. At this time, the rotating shaft 41 moves within the movable groove 312, and the servo motor A43 moves on the outer casing 31. Sliding, saw teeth B421 and A321 remain engaged. Servo motor A43 operates, driving rotating shaft 41 to rotate. Rotating shaft 41 drives rotating cylinder 42 to rotate. Rotating cylinder 42, through the engagement of saw teeth B421 and A321, drives semi-circular clamping plate 32 to rotate within semi-circular base 33. At this time, protrusion 34 on the outer wall of semi-circular clamping plate 32 rotates within groove 331 on the inner wall of semi-circular base 33. Semi-circular clamping plate 32 drives spiral ground pile to rotate and adjust its angle. The welding mechanism 1 completes automatic welding. After welding, the servo motor B47 drives the semi-circular clamp 32 to release the spiral pile. The conveying mechanism 2 continues to move the spiral pile to the next welding position or directly to the storage location. The top of the support member 22 on the conveyor belt 21 matches the curvature of the outer wall of the spiral pile, which can stabilize the spiral pile during the conveying process. The gap between the support members 22 can provide a place for the welded nut, preventing the nut from directly contacting the conveyor belt 21 and causing damage to the conveyor belt 21. The automatic nut welding process may be before or after the spiral plate welding process on the side of the spiral pile. If it is after the spiral plate welding process, the support member 22 and the spiral plate can be made as a set. The spacing between the support members 22 is equal to or a multiple of the pitch of the spiral plate, so that the side of the spiral plate closest to the conveyor belt 21 is located between the support members 22, ensuring normal transportation.
