Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and specifically relates to an automated welding device. Background Technology

[0002] On construction sites, steel pipes are widely used in core processes such as scaffolding erection, structural support systems, and pipeline laying. The quality of their connections directly determines construction safety and structural stability, and welding is a key process for achieving reliable steel pipe connections. With the development of industrialized and intelligent construction, various fully automated welding equipment has been widely adopted on-site, replacing traditional manual welding in scenarios where there is sufficient operating space or the workpiece can be moved to the equipment's work area.

[0003] A search revealed that CN120696566A discloses an automated on-site welding device for building steel bars, including a mounting base. A clamping plate is fixedly connected inside the mounting base, and an upsetting plate is slidably connected inside the mounting base. A clamping mechanism is provided above both the clamping plate and the upsetting plate, and two shielding mechanisms are provided inside the mounting base.

[0004] In actual construction, there is a need to weld steel pipes in relative positions after some steel pipes are fixed and installed. The welding area is often characterized by a small space due to construction layout limitations, with no redundant space required for manual operation. At the same time, the steel pipes are fixed and cannot be disassembled and moved to the work area of ​​automated welding equipment. Existing automated welding equipment relies on workpiece transfer or requires reserved equipment operation space, which is difficult to adapt to the site conditions of fixed workpieces and small working space, resulting in automated equipment being unable to directly carry out welding in such scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide an automated welding device to solve the problem mentioned in the background art that existing automated welding devices rely on workpiece transfer or require reserved equipment operating space, making it difficult to adapt to on-site conditions where workpieces are fixed and the working space is small.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automated welding device, comprising: Support frame; The adjustment frame is movably installed on the inner circumference of the support frame and can move in a circular motion along the inner circumference of the support frame.

[0011] In one embodiment, a groove is provided on the inner wall of the adjustment hole, and a slider is installed on one side of the adjustment seat, with the slider installed in the groove.

[0012] In one embodiment, the support frame has a semi-circular frame structure with a diameter adapted to the outer circumferential contour of the steel pipe to be welded.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-5 An automated welding device includes: a support frame 100; The adjusting frame 200 is movably installed on the inner circumference of the support frame 100 and can move in a circular motion along the inner circumference of the support frame 100. The welding machine 203 is slidably mounted on the adjusting frame 200 and can move around the central axis of the adjusting frame 200 to adjust the welding operation position of the welding machine 203.

[0025] Specifically, the support frame 100 serves as the fixed bearing base for the equipment, providing a stable guide path for the adjustment frame 200 to move circumferentially along its inner periphery, ensuring that the adjustment frame 200 can move smoothly to the recessed area below the pipe. The adjustment frame 200 is movably installed on the inner periphery of the support frame 100, and its movement trajectory is preset to cover the path of the recessed area below the pipe. It can not only support the welding machine 203, but also realize the position transfer of the welding machine 203 over a large range through its own circumferential movement, transporting the welding machine 203 from the area that is easy to initially adjust to the working area of ​​the recessed area.

[0026] Specifically, the welding machine 203 is slidably mounted on the adjusting frame 200. The adjusting frame 200 is equipped with a sliding structure adapted to the welding machine 203, providing a moving channel for the welding machine 203 along the extension direction of the adjusting frame 200. This allows the welding machine 203 to slide and adjust its position on the adjusting frame 200, completing the initial position calibration with the point to be welded. This avoids the situation where the adjusting frame 200 moves the welding machine 203 to the recessed area and then cannot be adjusted due to the limited space. When operation is required, the welding machine 203 is first pushed to slide along the adjusting frame 200 to the preset adapted position, ensuring that the welding angle of the welding machine 203 is initially matched with the point to be welded. Then, the adjusting frame 200 is driven to move in a circular motion along the inner circumference of the support frame 100, moving the welding machine 203 towards the recessed area below the pipe until the welding machine 203 reaches the point to be welded. At this point, the welding machine 203 has completed precise positioning through two steps of adjustment and can be directly started for welding operations.

[0027] In one embodiment, the support frame 100 includes: The first power source 101 is installed on the support frame 100; The first gear 102 is mounted on the power shaft of the first power source 101, and the outer peripheral wall of the adjustment frame 200 is provided with a first rack 103, which meshes with the first gear 102.

[0028] In the above technical solution, the first power source 101 is a servo motor, or it can be a stepper motor. The first power source 101 transmits its rotational power to the first gear 102, driving the first gear 102 to rotate around the power shaft axis. Utilizing the motion conversion characteristics of gear and rack transmission, the rotational motion of the first gear 102 can be converted into linear motion of the adjusting frame 200 along the inner circumference of the support frame 100 through the meshing force between the tooth surfaces. When it is necessary to send the welding machine 203 to the recessed area below the pipe, the welding machine 203 is first calibrated on the adjusting frame 200 by sliding adjustment on the adjusting frame 200. Then, the first power source 101 on the support frame 100 is started. The first power source 101 drives the first gear 102 to rotate, and through gear and rack meshing, drives the adjusting frame 200 to move gradually towards the recessed area along the inner circumference of the support frame 100 until the adjusting frame 200 drives the welding machine 203 to the preset working position in the recessed area below the pipe.

[0029] In one embodiment, the inner peripheral wall of the support frame 100 is provided with a moving groove extending circumferentially therein, and the outer peripheral wall of the adjustment frame 200 is provided with a corresponding moving block 104. The moving block 104 is slidably engaged in the moving groove to guide the movement of the adjustment frame 200.

[0030] In one embodiment, the adjustment frame 200 has an adjustment hole 201 extending along its length, and an adjustment seat 202 is slidably mounted in the adjustment hole 201. The welding machine 203 is detachably mounted on the adjustment seat 202.

[0031] In one embodiment, a control groove 206 is provided on one inner wall of the adjustment hole 201, a second rack 207 is provided on the groove wall of the control groove 206, a second power source 208 is installed on the adjustment seat 202, a second gear 209 is drivenly connected to the power output shaft of the second power source 208, and the second gear 209 meshes with the second rack 207 to drive the adjustment seat 202 to slide along the adjustment hole 201.

[0032] In the above technical solution, the adjusting seat 202 is assembled in the adjusting hole 201. On the one hand, it supports the welding machine 203, and on the other hand, it drives the welding machine 203 to adjust its position through its own sliding. The detachable connection design facilitates the replacement and maintenance of the welding machine 203. The control groove 206 on one side of the inner wall of the adjusting hole 201 provides installation space for the second rack 207. The second rack 207 is fixed to the groove wall of the control groove 206 to form a fixed transmission tooth surface. The second power source 208 is installed on the adjusting seat 202, and its power output shaft is connected to the second gear 209. When it is necessary to adjust the position of the welding machine 203 on the adjusting frame 200, the second power source 208 is started, driving the second gear 209 to rotate around its own axis. Since the second gear 209 meshes with the second rack 207, the interaction force between the tooth surfaces converts the rotational motion of the second gear 209 into the linear motion of the adjusting seat 202 along the length direction of the adjusting hole 201, thereby realizing the initial position adjustment of the welding machine 203.

[0033] In one embodiment, a groove 204 is provided on the inner wall of the adjustment hole 201, and a slider 205 is installed on one side of the adjustment seat 202, with the slider 205 installed in the groove 204.

[0034] In one embodiment, the support frame 100 has a semi-circular frame structure, the diameter of which is adapted to the outer circumferential contour of the steel pipe to be welded.

[0035] In one embodiment, the adjustment frame 200 has a C-shaped frame structure, and its opening size is larger than the diameter of the steel pipe to be welded.

[0036] In a preferred embodiment, it further includes: The slide rail 300 is located on one side of the adjusting frame 200; The sliding seat 301 is mounted on the slide rail 300, and the adjusting bracket 200 is connected to the sliding seat 301.

[0037] In a preferred embodiment, a connecting rod 302 is mounted on the sliding seat 301, and a telescopic rod 303 is mounted on the connecting rod 302. The telescopic direction of the telescopic rod 303 is perpendicular to the extension direction of the slide rail 300, and the sliding seat 301 is connected to one end of the telescopic rod 303.

[0038] The slide rail 300 serves as a guide base for the adjustment frame 200 to move in a specific direction. Its fixed configuration provides a stable sliding path for the sliding seat 301, limiting the sliding seat 301 to move only along the extension direction of the slide rail 300. The sliding seat 301 is slidably connected to the slide rail 300 and directly connected to the adjustment frame 200, allowing the adjustment frame 200 to move synchronously along the slide rail 300 as the sliding seat 301 slides, providing a basis for position adjustment of the adjustment frame 200 in this direction. The connecting rod 302 installed on the sliding seat 301 is used to fix the telescopic rod 303, forming a connection support between the telescopic rod 303 and the sliding seat 301. The telescopic direction of the telescopic rod 303 is designed to be perpendicular to the extension direction of the slide rail 300, with one end connected to the sliding seat 301. Through the telescopic action of the telescopic rod 303, the sliding seat 301 and the adjustment frame 200 connected to it can be driven to move in a direction perpendicular to the slide rail 300, realizing fine-tuning of the position of the adjustment frame 200 in this vertical direction.

[0039] The working principle and usage process of this utility model are as follows: Before performing pipe welding, the steel pipe to be welded is positioned at the preset working position, so that the support frame 100 is in corresponding contact with the outer circumference of the steel pipe; the second power source 208 on the adjusting seat 202 is started, and the second power source 208 drives the second gear 209 on the power output shaft to rotate. Because the second gear 209 meshes with the second rack 207 in the control groove 206 on one side of the adjusting hole 201, the rotational motion of the second gear 209 is converted into the force of the tooth surface through the force of the adjusting seat 202 along the length of the adjusting hole 201. The linear motion in the degree direction causes the slider 205 on one side of the adjusting seat 202 to slide synchronously within the groove 204 on the inner wall of the adjusting hole 201. The adjusting seat 202 drives the welding machine 203, which is detachably mounted on it, to move synchronously until the welding machine 203 is adjusted to a preset position that initially matches the welding point, thus completing the initial position calibration of the welding machine 203. If it is necessary to fine-tune the position of the adjusting frame 200 perpendicular to the extension direction of the slide rail 300, the telescopic rod 303 connected to the connecting rod 302 on the sliding seat 301 is activated. The telescopic rod 303 moves along the direction perpendicular to the slide rail 300. The extension and retraction of the 00 direction causes the connected sliding seat 301 to move along the vertical direction on the slide rail 300. The sliding seat 301 drives the adjusting frame 200 to make synchronous fine adjustments, ensuring that the position of the adjusting frame 200 is adapted to the subsequent circular motion path. Then, the first power source 101 on the support frame 100 is activated. The first power source 101 drives the first gear 102 on the power shaft to rotate. The first gear 102 meshes with the first rack 103 on the outer peripheral wall of the adjusting frame 200, converting the rotational motion into linear motion of the adjusting frame 200 along the inner circumference of the support frame 100. The moving block 104 on the outer wall of the adjusting frame 200 slides and guides within the moving groove on the inner circumferential wall of the support frame 100, causing the adjusting frame 200 to move in a circular motion along the inner circumference of the support frame 100, thereby driving the welding machine 203 to gradually move towards the recessed area below the pipe. When the welding machine 203 approaches the point to be welded, if further adjustment of the welding angle is required, the welding machine 203 is driven to rotate around the central axis of the adjusting frame 200 until the welding machine 203 is precisely aligned with the point to be welded in the recessed area. Finally, the welding machine 203 is started to perform the welding operation, completing the entire welding process.
