[0013] This utility model provides an auxiliary welding device for automobile seats with a frame positioning fixture, which has the following advantages: 1. This utility model utilizes a positioning clamp structure with a rotating base and a damping hinge design. This allows the positioning ring and fixing ring to be flexibly adjusted and positioned according to actual welding requirements, effectively improving the accuracy, stability, and structural flexibility of the welding process. Simultaneously, the damping hinge structure on one side of the positioning ring not only facilitates quick clamping and disassembly of the welded parts but also ensures stability during clamping through its damping characteristics, reducing welding deviations caused by vibration or impact. This enables precise positioning and stable clamping of the automotive seat frame, effectively preventing frame displacement or shaking during welding. This significantly improves the precision and quality of welding, ensuring the structural stability and safety of the welded car seats. Furthermore, the movable and detachable structure between the positioning fixture components and the first and second auxiliary frames allows for rapid adjustment and adaptation to different models and specifications of car seat frames, greatly enhancing the equipment's versatility and practicality. This effectively reduces production costs and equipment replacement frequency. Simultaneously, this modular design facilitates equipment maintenance and repair; when a component is damaged or requires an upgrade, it can be replaced individually without replacing the entire equipment, further reducing maintenance costs and time.

[0014] 2. This utility model, through the structural design of the first and second auxiliary frames, features an adjustment groove structure on the surface of the adjustment plate on the first auxiliary frame, allowing the adjustment bracket to be adjusted vertically according to welding requirements at different heights, thus providing auxiliary support. The assembly angle plate and stabilizing support further enhance the structural strength and stability of the entire auxiliary equipment. The second auxiliary frame, through the connection between the combined frame and the second frame body, and the design of the docking seat, enables it to achieve a stable structural connection with the first auxiliary frame and supporting components, jointly forming a stable and reliable welding auxiliary platform. In addition, the structural design of the adjustment bracket, with the coordinated work of its stabilizing frame, carrying frame, adjustment support frame, and bracket body, provides a stable and adjustable support platform for the welded parts. In particular, the movable shaft connection between the adjustment support frame and the bracket body and the arc-shaped adjustment groove structure allow the bracket body to be adjusted within a certain range, thereby adapting to welded parts of different shapes and sizes, greatly improving the flexibility and efficiency of welding.

[0015] 3. This utility model, through the structural design of the supporting components, including the combined design of the supporting crossbeam, the combined frame, and the fixed pillar, provides a solid bottom support for the entire auxiliary equipment. The interconnection between the supporting crossbeam and the combined frame, and the docking combination between the combined frame and the docking seat, allow the supporting components to be tightly integrated with the second auxiliary frame, jointly bearing various forces and vibrations during the welding process. The bolt mounting holes at the bottom of the fixed pillar and the stabilizing pillar facilitate the fixing and installation of the entire auxiliary equipment in the working environment, thereby ensuring that the equipment remains stable during the welding process and avoiding welding quality problems caused by equipment movement. At the same time, this support structure design also has a certain degree of seismic resistance, effectively absorbing and dispersing the vibration energy generated during the welding process, reducing the impact on welding accuracy, and further improving the stability and reliability of the welding. In addition, the synergistic effect between the supporting components, the first auxiliary frame, and the second auxiliary frame constitutes a complete and stable welding auxiliary system, providing a strong guarantee for high-quality welding of automotive seats.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 6 As shown, an auxiliary welding device for automobile seats with a frame positioning fixture includes a first auxiliary frame 1 and a positioning fixture component 3. A second auxiliary frame 2 is connected and installed at one end of the first auxiliary frame 1. The positioning fixture component 3 is symmetrically and movably installed on the surfaces of the first auxiliary frame 1 and the second auxiliary frame 2.

The positioning fixture component 3 includes a damping hinge 301, a fixed seat 302, a positioning ring frame 303, a rotating seat 304, and a fixed ring frame 305. The upper end of the damping hinge 301 is connected to the fixed seat 302, and the positioning ring frame 303 is installed on the top of the fixed seat 302. The bottom of the damping hinge 301 is connected and installed to the rotating seat 304, and the rotating seat 305... The bottom of 04 is equipped with a fixed ring frame 305. One side of the positioning ring frame 303 is provided with a damping hinge structure to realize the opening and closing of the structure. The other side of the positioning ring frame 303 has two sets of holes for bolt installation symmetrically opened vertically. The four diagonal corners of the rotary seat 304 are all provided with holes for bolt installation vertically. The fixed ring frame 305 adopts a structure of upper and lower splicing, and two sets of holes for bolt installation are opened at both ends. The damping characteristics of the damping hinge 301 are used to make the positioning ring frame 303 and the fixed ring frame 305 able to smoothly transition when adjusting the angle. The cooperative design of the rotary seat 304 and the damping hinge 301 allows the positioning ring frame 303 and the fixed ring frame 305 to be flexibly adjusted and positioned according to the actual welding requirements.

[0020] like Figures 1 to 6As shown, the first auxiliary frame 1 includes a first frame body 101, an adjusting plate 102, a support rod 103, an assembly corner plate 104, and a stabilizing column 105. The adjusting plate 102 is symmetrically installed on the bottom of the first frame body 101 near the second auxiliary frame 2, and the support rod 103 is horizontally connected to the lower end of the adjusting plate 102. The assembly corner plate 104 is symmetrically installed on the bottom side of the first frame body 101 away from the adjusting plate 102, and the stabilizing column 105 is symmetrically installed on the bottom of the first frame body 101 away from the second auxiliary frame 2. The second auxiliary frame 2 includes a combination frame 201 and a second frame body 202. The second frame 202 is connected and installed at both ends of the combined frame 201, with docking seats 203 and connecting bases 203 symmetrically arranged at the bottom bend of the second frame 202 near the vertical central axis of the combined frame 201. One bottom end of the second frame 202 is connected to the end of the first frame 101 away from the stabilizing support 105. The stabilizing support 105 has holes for bolt installation at the four opposite corners of its bottom. The surface of the adjusting plate 102 has holes for adjusting the vertical angle of the adjusting bracket 4. The adjusting bracket 4 includes a stabilizing frame 401, a carrying frame 402, an adjusting support frame 403, and a support. The frame body 404 and the stabilizer 401 have a handle 402 installed in the middle. Adjustable support frames 403 are symmetrically installed on the top of the stabilizer 401. A bracket body 404 is connected to the side of the adjustable support frame 403 closest to the vertical central axis of the stabilizer 401. The adjustable support frames 403 are symmetrically arranged on both sides of the bracket body 404. The connection between the bracket body 404 and the adjustable support frame 403 at one end is a movable shaft connection. An arc-shaped adjustment groove structure is provided at the other end of the bracket body 404 and the adjustable support frame 403 to allow for a certain degree of angle adjustment of the bracket body 404. The stabilizer 401 has a handle 402 installed in the middle of the middle of the stabilizer 401. Adjustable support frames 403 are symmetrically installed on both sides of the bracket body 404. The front and rear ends on both sides are respectively mounted on the lower middle part of the first frame 101 via the adjustment plate 102 and the assembly angle plate 104. The adjustment groove on the surface of the adjustment plate 102 can precisely control the vertical movement range of the adjustment bracket 4, ensuring that the bracket body 404 can achieve the ideal support position when adapting to different welding parts heights, while ensuring the stability and accuracy of the adjustment process. The design of the movable shaft connection allows the bracket body 404 and the adjustment support frame 403 to rotate flexibly, while the arc-shaped adjustment groove structure further expands the angle adjustment range of the bracket body 404 to meet the support requirements of various complex-shaped welding parts.

[0021] like Figures 1 to 6As shown, the support component 5 includes a support crossbeam 501, a combined frame 502, and a fixed support column 503. The left and right ends of the support crossbeam 501 are connected to the combined frame 502, and the bottom of the combined frame 502 is symmetrically provided with fixed support columns 503. The support crossbeam 501 is horizontally symmetrically arranged in two sets and connected to the combined frame 502. The side of the combined frame 502 away from the support crossbeam 501 is connected to the docking seat 203. The bottom of the fixed support column 503 has holes for bolt installation at four opposite corners. The rigid connection between the support crossbeam 501 and the combined frame 502 effectively disperses the vertical and horizontal forces generated during welding, ensuring that the support component 5 is not easily deformed during long-term use. The bolt installation holes at the bottom of the fixed support column 503 are countersunk, which ensures the flatness of the installation surface and enhances the contact stability with the work platform by thickening the bottom plate.

[0022] In summary, as Figures 1 to 6 As shown, the automotive seat welding auxiliary equipment with frame positioning fixture is used by first placing the equipment in a suitable working position. Using the bolt mounting holes at the bottom of the stabilizing support 105 and the fixed support 503, the equipment is securely fixed to the working platform with bolts, ensuring that the equipment will not move or shake during the welding process. Next, according to the model and specifications of the automotive seat frame to be welded, the number and position of the positioning fixture components 3 are appropriately adjusted. The fixed ring frame 305 is then used to install it at different positions on the surfaces of the first auxiliary frame 1 and the second auxiliary frame 2. Simultaneously, through the cooperation of the damping hinge 301 and the swivel seat 304, the angles of the positioning ring frame 303 and the fixed ring frame 305 can be flexibly adjusted, enabling precise installation, fixing, positioning, and clamping of the automotive seat frame. Furthermore, the damping hinge structure on one side of the positioning ring frame 303 allows for convenient and quick clamping and disassembly of the welded parts, improving work efficiency. Then, according to the height requirements of the welded parts, the adjustment bracket 4 is adjusted up and down by means of the adjustment groove opened on the surface of the adjustment plate 102. By using the movable shaft connection and the arc-shaped adjustment groove structure, in conjunction with the positioning assistance of the external bolts, the bracket body 404 can be adjusted within a certain range to adapt to welded parts of different shapes and sizes, and to provide a stable and adjustable auxiliary support platform for the welded parts.

[0023] During the welding process, the first auxiliary frame 1, the second auxiliary frame 2, and the support component 5 together form a stable and reliable welding auxiliary platform. The first frame 101, support rod 103, and stabilizing column 105 on the first auxiliary frame 1 enhance the structural strength and stability of the equipment. The second auxiliary frame 2 achieves stable docking with the first auxiliary frame 1 and the support component 5 through the connection between the combined frame 201 and the second frame 202, as well as the design of the docking seat 203. The support component 5 provides solid bottom support for the entire equipment through the combined design of the support crossbeam 501, the combined frame 502, and the fixed column 503, effectively withstanding various forces and vibrations during the welding process. Finally, after welding is completed, the equipment can be easily maintained and repaired. Because the equipment adopts a modular design, when a certain part is damaged or needs to be upgraded, the part can be replaced individually without replacing the entire equipment, thereby reducing maintenance costs and time. At the same time, this design also facilitates the cleaning and maintenance of the equipment and extends its service life.
