Description

Technical Field

[0001] This utility model belongs to the field of fire extinguisher welding technology, and relates to a fire extinguisher hanging welding device. Background Technology

[0002] The fire extinguisher hook is a key component of the fire extinguisher mounting base, used to stably suspend the fire extinguisher on walls, brackets, or other installation locations. Its welding quality directly affects the stability of the fire extinguisher's fixation and its safety during use. In existing technologies, welding the fire extinguisher hook to the mounting base largely relies on manual operation: the operator must manually place the hook into the pre-set welding position on the mounting base, temporarily fix it using clamps or hand grips, and then perform the welding operation using a welding torch. This method has significant drawbacks: First, manual positioning accuracy is low. The relative position of the hanging bracket and the fixing seat is easily deviated due to hand tremors, visual errors, etc., resulting in mismatch between the mounting holes of the hanging bracket and the wall mounting parts after welding, or deformation of the fixing seat due to uneven welding stress distribution, affecting product consistency and pass rate. Second, welding efficiency is low. The positioning, fixing, and welding process must be completed manually one by one, and the welding time for a single workpiece is long, making it difficult to meet the needs of mass production. Especially in large-scale manufacturing scenarios, the production progress is severely constrained by the speed of manual operation. Third, the operation is cumbersome and labor-intensive. Operators must simultaneously manage workpiece fixing and welding operations. High-temperature welding arcs and metal spatter pose potential threats to personal safety, and prolonged operation can easily lead to fatigue, further reducing the stability of welding quality. In addition, manual welding depends on the skill level of the operator, and product quality is greatly affected by individual differences, resulting in significant fluctuations in the pass rate and increasing subsequent quality inspection and rework costs. With the development of large-scale and automated fire extinguisher production, traditional manual welding methods can no longer meet the production needs of high efficiency, high precision, and low reliance on manual labor.

[0003] A welding device for fire extinguisher brackets, patent publication number CN222511467U, relates to the field of welding device technology. It includes a welding table with a rotating platform rotatably connected to its upper surface. A positioning component is provided on the upper surface of the rotating platform. The positioning component includes a gantry frame fixedly installed on the upper surface of the rotating platform. A first motor is fixedly installed on the upper surface of the gantry frame, and a lead screw is fixedly installed at the output end of the first motor. A moving part is threadedly connected to the outer surface of the lead screw, and a driven block is fixedly installed on the side surface of the moving part. This fire extinguisher bracket welding device, through the positioning component, can effectively fix and limit the various parts that make up the fire extinguisher bracket, allowing for precise alignment of each part. This frees up the worker's other hand, enabling them to perform welding operations with both hands, improving welding accuracy and efficiency, and ensuring the progress of the welding work. The positioning assembly of the aforementioned device achieves positioning via a gantry frame, a first motor, a lead screw, a moving component, a driven block, a first telescopic column, a return spring, a pressure plate, a locking block, a spreading rod, an arc-shaped positioning plate, an L-shaped connecting rod, and a second telescopic column. Positioning is achieved through the lead screw driving downward movement, the telescopic column retracting, the locking block driving the spreading rod, and the arc-shaped positioning plate expanding outward. This transmission chain is long and relies on the elastic deformation of the springs, making it prone to failure due to component wear or spring fatigue. Therefore, those skilled in the art urgently need to solve the aforementioned technical problems. Utility Model Content

[0004] To address the aforementioned problems and deficiencies, this invention reduces the workload of workers while improving production efficiency and increasing the efficiency of hanging welding.

[0005] To solve the above-mentioned technical problems, this utility model relates to a fire extinguisher hanging and welding device for fixing the fire extinguisher fixing seat and welding the hanging to the fire extinguisher fixing seat. The device is characterized by including a supporting base plate, a positioning seat, a displacement component and a welding head.

[0006] An installation plate is fixed on the support base plate, and the displacement component is installed on the top of the installation plate. The positioning seat is disposed on the support base plate and located below the displacement component, and is used to position and fix the fire extinguisher fixing seat.

[0007] The displacement assembly includes a lead screw, a moving part that cooperates with the lead screw, a hydraulic cylinder, and a drive motor. The power output end of the drive motor is connected to the lead screw to drive the lead screw to rotate. The moving part is mounted on the lead screw, the hydraulic cylinder is fixed to the moving part in the vertical direction, and the welding head is installed on the telescopic end of the hydraulic cylinder.

[0008] The drive motor drives the lead screw to rotate, causing the moving component to move along the lead screw axis. The hydraulic cylinder drives the welding head to move in the vertical direction. The displacement component causes the welding head to move closer to or further away from the positioning seat in the horizontal or vertical direction.

[0009] By adopting the above technical solution and setting up an integrated structure consisting of a supporting base plate, a positioning seat, a displacement assembly, and a welding head, automated positioning and welding of fire extinguisher hanging devices are achieved. The positioning seat is used to stably fix the fire extinguisher mounting base, preventing workpiece displacement during welding. The displacement assembly, driven by a motor and a lead screw, moves the moving parts horizontally, while a hydraulic cylinder drives the welding head vertically. This allows for flexible adjustment of the relative position of the welding head and the positioning seat, replacing the traditional manual hand-held welding torch operation. This reduces positioning errors caused by human intervention, improves welding position accuracy and product consistency, and simultaneously increases welding efficiency and reduces the labor intensity of operators through automated mechanical movement.

[0010] Furthermore, the moving component is a mounting base, and the hydraulic cylinder is fixed to the lead screw through the mounting base; the top of the mounting plate is provided with a limiting plate extending along the axial direction of the lead screw, the limiting plate is located outside the lead screw, and the mounting base is fitted onto the limiting plate and slides in cooperation with the limiting plate.

[0011] By adopting the above technical solution, the moving part is clearly defined as the mounting base, and a limiting plate extending along the screw axis is set on the top of the mounting plate, so that the mounting base is fitted onto the limiting plate in a sliding fit. This structural design can accurately guide and limit the horizontal movement of the mounting base, effectively preventing the mounting base from rotating or shifting under the drive of the screw, ensuring the stability of the movement process, thereby ensuring the positional accuracy of the welding head when it moves in the horizontal direction, preventing welding position deviation caused by movement and shaking, and improving the reliability of welding quality.

[0012] Furthermore, the hydraulic cylinder is detachably mounted on the mounting base by bolts; a welding head mounting component is fixed to the bottom of the telescopic end of the hydraulic cylinder, and the welding head is mounted on the bottom of the welding head mounting component.

[0013] By adopting the above technical solution, the hydraulic cylinder is detachably installed on the mounting base using bolts, and a welding head mounting component is set at the bottom of the hydraulic cylinder's telescopic end, allowing the welding head to be installed at the bottom of the mounting component. This design achieves convenient disassembly and assembly of the hydraulic cylinder and the mounting base, facilitating future maintenance or replacement of the hydraulic cylinder. On the other hand, the welding head mounting component provides a stable mounting base for the welding head, ensuring a firm connection between the welding head and the telescopic end of the hydraulic cylinder during welding, preventing the welding head from loosening and affecting the welding effect. At the same time, the detachable structure also facilitates the replacement of suitable welding heads according to different welding requirements, improving the versatility of the device.

[0014] Furthermore, the welding head mounting component is provided with a through mounting hole, and the top of the welding head is provided with a positioning rod that matches the mounting hole. The positioning rod is inserted into the mounting hole and fixed by fasteners to position and install the welding head on the welding head mounting component.

[0015] By adopting the above technical solution, mounting holes are provided on the welding head mounting component. The positioning rod on the top of the welding head is inserted into the mounting holes and fixed with fasteners, which enables precise positioning and installation of the welding head and the welding head mounting component. This ensures that the axis of the welding head is consistent with the axis of the mounting hole, avoids skewness during welding head installation, and guarantees the accurate relative position of the welding head and the workpiece during welding. At the same time, the mating structure of the positioning rod and the mounting hole, combined with the fastener fixation, facilitates the quick installation and removal of the welding head, and ensures the stability of the welding head during welding, preventing displacement of the welding head due to vibration and improving the stability of welding quality.

[0016] Furthermore, the positioning seat includes a first positioning seat and a second positioning seat disposed opposite to each other; a positioning space for accommodating the fire extinguisher fixing seat is formed between the first positioning seat and the second positioning seat, the shape and size of the positioning space being adapted to the fire extinguisher fixing seat so as to jointly position the fire extinguisher fixing seat by means of the first positioning seat and the second positioning seat.

[0017] By adopting the above technical solution, the positioning seat is designed as a first positioning seat and a second positioning seat arranged opposite each other, forming a positioning space that is adapted to the fire extinguisher fixing seat. Through the joint action of the two positioning seats, the fire extinguisher fixing seat can be stably clamped from both sides, ensuring that the fixing seat will not shift horizontally or vertically during the welding process, and avoiding deviation of the hanging welding position due to loose workpiece. At the same time, the shape and size of the positioning space are adapted to the fixing seat, which can accommodate fixing seats of specific specifications, ensuring the fit of the positioning and improving the accuracy of workpiece positioning before welding.

[0018] Furthermore, the first positioning seat is fixed to the support base plate by bolts; a push cylinder is also installed on the support base plate, the telescopic end of the push cylinder extends along the relative direction of the first positioning seat and the second positioning seat and is connected to the second positioning seat, driving the second positioning seat to move closer to or further away from the first positioning seat in the horizontal direction, thereby adjusting the size of the positioning space.

[0019] By adopting the above technical solution, the second positioning seat is driven by a cylinder to move horizontally closer to or further away from the first positioning seat, thereby automatically adjusting the size of the positioning space and replacing the traditional manual adjustment of the positioning structure, thus improving positioning efficiency. The driving method of the cylinder can provide a stable clamping force, ensuring that the second and first positioning seats are firmly clamped to the fixed seat and the force is even, avoiding deformation of the fixed seat or unstable positioning due to uneven manual clamping force. At the same time, the adjustable positioning space allows the device to be adapted to fire extinguisher fixed seats of different sizes, improving the applicability and flexibility of the device and meeting diverse production needs.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model achieves uniform unfolding and fixation of the fishing net on the stretching trolley by slidably installing the stretching trolley inside the vessel body and setting mesh frames at both ends of its top and at least two mesh frames in the middle to form a multi-dimensional support structure. At the same time, through the connection between the stretching trolley and the traveling trolley, the traveling trolley drives the stretching trolley to slide, accurately adjusting the shaping position of the fishing net in the vessel, ensuring the stability and efficiency of the stretching and shaping process.

[0022] 2. This utility model uses a fixed support at the bottom of the vessel near the stretching carriage and at least three movable supports at the other positions. The fixed support restricts the displacement of one end of the vessel, while the movable supports allow the vessel to undergo slight deformation when it expands and contracts with heat. This reduces stress concentration caused by rigid support, improves the stability and service life of the vessel structure, and the multi-support layout distributes the weight, ensuring stable operation of the equipment.

[0023] 3. This utility model sets a slide rail inside the vessel body and installs rollers on the end of the stretching trolley near the vessel body to cooperate with the slide rail. This restricts the movement of the stretching trolley to the slide rail track, reduces sliding friction resistance, ensures smooth and straight movement, avoids uneven stretching of the fishing net due to deviation, and enhances the load-bearing capacity of the stretching trolley to ensure structural stability during the shaping process.

[0024] 4. This utility model fixes the bottom of the kettle lid to the traveling trolley, forming an integrated moving structure between the kettle lid and the traveling trolley. This enables the kettle lid to open and close synchronously when the traveling trolley drives the stretching trolley in and out of the kettle body. It simplifies the operation process without the need for an additional driving device. Furthermore, the fixed connection between the kettle lid and the traveling trolley improves the sealing of the opening and closing process, reduces heat loss inside the kettle, and improves the shaping efficiency.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. Figure 1 , Figure 2 , Figure 3 and Figure 4 As can be seen, the fire extinguisher hanging welding device disclosed in this utility model has a supporting base plate 1 as its basic load-bearing structure. The core components form a collaborative working system through precise assembly relationships. The specific assembly and positional relationships are as follows: The supporting base plate 1 serves as the basic platform of the device, and its upper space is divided into upper and lower layers. The lower layer is equipped with a positioning seat 2 for fixing the workpiece, and the upper layer supports the displacement component 3 through a fixed mounting plate. The positioning seat 2 and the displacement component 3 are vertically aligned to ensure that the welding head 4 driven by the displacement component 3 can accurately act on the workpiece on the positioning seat 2.

[0032] The displacement component 3 is the core mechanism for realizing the automated movement of the welding head 4. Its assembly relationship is based on the mounting plate: the top of the mounting plate is fixedly mounted with a lead screw 31 in the horizontal direction. One end of the lead screw 31 is connected to the power output end of the drive motor 34, which provides rotational power. A limiting plate 5 is set parallel to the outside of the lead screw 31. The limiting plate 5 is also fixed to the top of the mounting plate. Its length direction is consistent with the axial direction of the lead screw 31, forming a guide structure for the moving component 32. The moving component 32 is specifically a mounting seat (8). Its inner side is fitted onto the lead screw 31 through a threaded structure, and its outer side is fitted onto the limiting plate 5 to form a sliding fit. When the drive motor 34 drives the lead screw 31 to rotate, the mounting seat 8 moves axially under the threaded transmission of the lead screw 31. At the same time, under the constraint of the limiting plate 5, it avoids rotational deviation and realizes stable horizontal displacement. The lower part of the mounting base 8 is detachably mounted with a hydraulic cylinder via bolts along the vertical direction. The cylinder body of the hydraulic cylinder is rigidly connected to the mounting base 8, and the telescopic end extends vertically downward. A welding head mounting component 41 is fixedly installed at its bottom. The welding head 4 is detachably connected to the hydraulic cylinder through the welding head mounting component 41. A through mounting hole is opened on the welding head mounting component 41, and a positioning rod 7 adapted to the mounting hole is provided on the top of the welding head 4. After the positioning rod 7 is inserted into the mounting hole, it is fixed by fasteners such as bolts or pins to ensure the coaxiality of the welding head 4 and the telescopic end of the hydraulic cylinder, and to avoid positional deviation caused by loose connection during the welding process.

[0033] The positioning seat 2 serves as a workpiece fixing mechanism, comprising a first positioning seat 21 and a second positioning seat 22 arranged opposite to each other. Both are located on the upper surface of the support base plate 1 and directly below the displacement component 3, together forming a positioning space for accommodating fire extinguisher mounting seats. The first positioning seat 21 is rigidly fixed to the support base plate 1 by bolts, serving as a positioning reference. The second positioning seat 22 is a movable component, which is driven by a push cylinder 6 mounted on the support base plate 1. The cylinder body of the push cylinder 6 is fixed to the support base plate 1, and its telescopic end extends horizontally along the relative direction of the first positioning seat 21 and the second positioning seat 22. Its end is rigidly connected to the side of the second positioning seat 22. By the telescopic movement of the push cylinder 6, the second positioning seat 22 is driven to move closer to or further away from the first positioning seat 21 in the horizontal direction, thereby adjusting the size of the positioning space to accommodate fire extinguisher mounting seats of different sizes.

[0034] The device integrates the spatial layout of the positioning seat 2 and the displacement component 3 through the supporting base plate 1. The positioning seat 2 achieves precise fixation of the workpiece through the first positioning seat 21 and the movable second positioning seat 22. The displacement component 3 achieves horizontal displacement of the welding head 4 through the drive motor 34-lead screw 31 and vertical displacement through the hydraulic cylinder. With the guidance of the limit plate 5 and the positioning structure of the welding head mounting part 41, the various components ensure the motion accuracy through rigid connection or sliding cooperation, and together realize the automated welding operation of the fire extinguisher hanging.

[0035] In one embodiment, refer to Figure 1 , Figure 2 and Figure 3 As can be seen, the movement of the welding head 4 in this device is automatically controlled by the displacement component 3. Its core relies on the coordinated work of the drive motor 34, lead screw 31, moving component 32, and hydraulic cylinder, combined with the guiding effect of the limiting plate 5, to achieve precise horizontal and vertical displacement. The displacement component 3, as the driving core for the movement of the welding head 4, mainly consists of the power source drive motor 34, hydraulic cylinder, transmission mechanism lead screw 31, execution component moving component 32, and guide component limiting plate 5. These components form a complete displacement system through rigid connection and kinematic coordination. The drive motor 34 provides the power for horizontal movement, and the hydraulic cylinder provides the power for vertical movement. The two are controlled independently yet work together to achieve flexible adjustment of the welding head 4 in two-dimensional space.

[0036] Horizontal movement is driven by the lead screw 31. The power output end of the drive motor 34 is directly connected to one end of the lead screw 31 via a coupling or gear set. When the drive motor 34 starts, the rotational motion of its output shaft is directly transmitted to the lead screw 31, causing the lead screw 31 to rotate around its own axis. The lead screw 31 is fixedly mounted horizontally on the top of the mounting plate, and a moving part 32, specifically a mounting base 8, is fitted on its outer side. The inner side of the mounting base 8 has an internal thread structure that matches the external thread of the lead screw 31, forming a helical transmission pair through thread engagement. When the lead screw 31 rotates, the mounting base 8 moves horizontally along the axial direction of the lead screw 31 under the action of thread friction, thereby adjusting the horizontal position of the welding head 4. To prevent the mounting base 8 from rotating synchronously with the lead screw 31 during movement, a limiting plate 5 is provided parallel to the outside of the lead screw 31 on the top of the mounting plate. The length direction of the limiting plate 5 is consistent with the axial direction of the lead screw 31. The outer side of the mounting base 8 is fitted onto the limiting plate 5 and forms a sliding fit. By restricting the rotational freedom of the mounting base 8, the limiting plate 5 ensures that it only moves in a straight line along the axial direction, thereby ensuring the stability and accuracy of horizontal movement.

[0037] The vertical movement is driven independently by a hydraulic cylinder, which directly acts on the welding head 4. The hydraulic cylinder is installed vertically at the lower part of the mounting base 8 of the moving part 32. Its cylinder body is rigidly connected to the mounting base 8 by bolts and moves horizontally synchronously with the mounting base 8. The telescopic end of the hydraulic cylinder extends vertically downward, and a welding head mounting component 41 is fixedly connected to its bottom. The welding head 4 is detachably fixed to the hydraulic cylinder through the welding head mounting component 41. The welding head mounting component 41 has a through mounting hole, and the top of the welding head 4 has a positioning rod 7 that matches the mounting hole. After the positioning rod (7) is inserted into the mounting hole, it is locked by fasteners such as bolts, so that the welding head 4 and the telescopic end of the hydraulic cylinder form a rigid connection. When the telescopic end of the hydraulic cylinder extends or retracts, it directly drives the welding head mounting component 41 and the welding head 4 to move vertically, thereby realizing the height adjustment between the welding head 4 and the workpiece.

[0038] When the drive motor 34 drives the lead screw 31 to rotate, the moving part 32 of the mounting base 8 moves horizontally along the guide of the limiting plate 5, simultaneously driving the hydraulic cylinder at the bottom of the mounting base 8 and the welding head 4 to move horizontally in sync, adjusting the relative position of the welding head 4 with the workpiece on the positioning seat 2 in the horizontal direction. When it is necessary to adjust the height of the welding head 4, the hydraulic cylinder works independently, and its extension end drives the welding head 4 to move up and down, realizing the contact or separation with the welding surface of the workpiece. Through the independent control of the drive motor 34 and the hydraulic cylinder, combined with the precise transmission of the lead screw 31 and the stable guidance of the limiting plate 5, the welding head 4 can achieve automated and high-precision position adjustment in the horizontal and vertical directions, meeting the needs of different welding positions, replacing the traditional manual hand-held welding gun operation, and improving welding efficiency and position accuracy.

[0039] In one embodiment, refer to Figure 1 and Figure 4 As can be seen, the positioning seat 2 specifically consists of a first positioning seat 21 and a second positioning seat 22 arranged opposite to each other. Both are installed on the support base plate 1 and located directly below the displacement component 3, together forming a positioning space for accommodating the fire extinguisher fixing seat. The shape and size of this positioning space are adapted to the fire extinguisher fixing seat to be welded, and preliminary positioning is achieved through physical contour fitting. The first positioning seat 21 serves as a positioning reference and is rigidly fixed to the support base plate 1 by bolts. Its position remains constant, providing stable lateral support for the fixing seat. The second positioning seat 22 is a movable adjustment component, symmetrically distributed with the first positioning seat 21. The opposing surfaces of the two are machined with positioning surfaces that match the contour of the fixing seat. The surface contact increases the clamping area and avoids workpiece deformation caused by local stress concentration.

[0040] The fixed setting of the first positioning seat 21 ensures the uniqueness of the positioning reference and avoids the accumulation of positioning errors caused by the movement of both seats. The second positioning seat 22 is dynamically adjusted through a transmission connection with the push cylinder 6. The cylinder body of the push cylinder 6 is fixed to the support base plate 1, and its telescopic end extends horizontally along the relative direction of the first positioning seat 21 and the second positioning seat 22, and is rigidly connected to the side of the second positioning seat 22. When the push cylinder 6 is activated, its telescopic end extends or retracts, directly driving the second positioning seat 22 to move closer to or away from the first positioning seat 21 in the horizontal direction. The size of the positioning space is adjusted by changing the distance between the two. When the fixed seat is placed in the positioning space, the push cylinder 6 drives the second positioning seat 22 to move closer to the first positioning seat 21 until the positioning surfaces on both sides are tightly fitted with the fixed seat. The stable thrust output by the cylinder forms a clamping force, which firmly locks the fixed seat in the positioning space. After welding is completed, the push cylinder 6 drives the second positioning seat 22 to move in the opposite direction, increasing the positioning space and facilitating the removal of the workpiece.

[0041] The cylinder 6 plays a dual role in the positioning process: firstly, its driving force replaces traditional manual adjustment, enabling automated adjustment of the positioning space and improving operational efficiency; secondly, the pneumatic drive characteristic of the cylinder outputs a continuous and uniform clamping force, avoiding deformation or instability of the fixed seat caused by uneven force during manual clamping, ensuring that the fixed seat does not shift horizontally or wobble vertically during welding, significantly improving positioning stability. The adjustment principle of the positioning space is based on the linear movement of the second positioning seat 22. By controlling the stroke of the cylinder 6, stepless adjustment of the positioning space size can be achieved, allowing the device to adapt to different specifications of fire extinguisher fixed seats with differences in width and thickness, breaking through the limitation of traditional fixed positioning structures that can only adapt to workpieces of a single size. At the same time, the shape of the positioning space matches the fixed seat, and with the surface contact clamping of the two seats, the fit between the fixed seat and the positioning seat 2 is further ensured, avoiding positioning deviations caused by gaps. From a structural design perspective, this ensures the accuracy and reliability of positioning, providing a stable workpiece foundation for the subsequent welding operation of the welding head 4.

[0042] Working principle: The base plate 1 serves as the basic load-bearing platform. The positioning and welding mechanisms are arranged in layers: the lower positioning seat 2 is responsible for fixing the workpiece and consists of a first positioning seat 21 and a second positioning seat 22 positioned opposite each other. The first positioning seat 21 is bolted to the base plate 1 to form a reference. The second positioning seat 22 is connected to a push cylinder 6 on the base plate 1. By extending or retracting the push cylinder 6, it moves horizontally closer to or further away from the first positioning seat 21, adjusting the positioning space between them to match the shape and size of the fire extinguisher mounting base, thus achieving stable clamping of mounting bases of different specifications. The upper displacement assembly 3 is installed on the base plate 1. At the top of the mounting plate, the drive motor 34 drives the lead screw 31 to rotate, which in turn drives the moving part 32 mounting seat 8, which is mounted on the lead screw 31, to move axially. At the same time, the outer side of the mounting seat 8 is fitted onto the limiting plate 5 at the top of the mounting plate to form a sliding fit, ensuring that there is no rotational offset during horizontal movement. The lower part of the mounting seat 8 is fixed with a hydraulic cylinder in the vertical direction. Its telescopic end is connected to the welding head 4 through the welding head mounting part 41. The positioning rod 7 at the top of the welding head 4 is inserted into the mounting hole of the welding head mounting part 41 and fixed by fasteners. The hydraulic cylinder drives the welding head 4 to move vertically. Finally, the displacement component 3 realizes the precise displacement of the welding head 4 in the horizontal and vertical directions, completing the hanging welding of the fixed seat on the positioning seat 2.

[0043] Traditional manual welding relies on handheld welding torches, which are prone to large positioning errors due to unstable operation, and the workpiece needs to be manually fixed and is prone to displacement. This device, through the double-seat clamping structure of the positioning seat 2 and the stable clamping force provided by the push cylinder 6, ensures that the workpiece does not shift during the welding process. In conjunction with the guiding effect of the limit plate 5 on the moving part 32, it prevents the welding head 4 from deviating when moving horizontally, significantly improving the welding position accuracy. Manual operation is labor-intensive and inefficient. This device replaces manual hand operation with the automated drive of the drive motor 34 and hydraulic cylinder, realizing the mechanical adjustment of the position of the welding head 4, reducing manual intervention, improving welding efficiency and reducing labor intensity. Traditional equipment has a fixed positioning structure, which is difficult to adapt to workpieces of different sizes. This device adjusts the positioning space by pushing the cylinder 6, making the device compatible with various specifications of fire extinguisher fixing seats, thus expanding its applicability. In addition, the bolted connection between the hydraulic cylinder and the mounting seat 8, and the detachable design of the welding head 4 and the welding head mounting part 41, facilitate the later maintenance and replacement of parts, solving the problem of inconvenient maintenance of traditional welding equipment, and further improving the practicality and versatility of the device.
