[0045] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0046] like Figure 1-5 As shown, a seat frame welding tool comprises:

[0047] A fixed bottom frame 100, on which a plurality of limit-lifting seats 110 are provided;

[0048] The position limiting support seat 110 is suitable for carrying the main frame 200;

[0049] Longitudinal limiting mechanisms, two longitudinal limiting mechanisms are slidably mounted on the fixed bottom frame 100, and the two longitudinal limiting mechanisms abut against the longitudinal sides of the main frame 200;

[0050] The clamping and fixing mechanism is installed on the fixed bottom frame 100 and the longitudinal limiting mechanism.

[0051] The pressing and fixing mechanism abuts against the upper surface of the main frame 200 .

[0052] Specifically, Figure 1-4 As shown, the seat frame welding tooling also includes a single-side lifting mechanism, and the single-side lifting mechanism can be the following structure:

[0053] A lifting driving member 300, the lifting driving member 300 is arranged in a limiting lifting seat 110 on one side of the fixed bottom frame 100;

[0054] The main frame 200 is provided with a bottom cross beam 210;

[0055] The end of the lifting rod of the lifting driving member 300 is suitable for abutting against the bottom crossbeam 210 of the main frame 200 to adjust the lateral inclination of the main frame 200.

[0056] In this embodiment, if Figure 1-4As shown, the function of the unilateral lifting mechanism is to adjust the lateral inclination of the main frame 200 so as to more accurately position and fix the main frame 200 on the fixed bottom frame 100. By adjusting the unilateral lifting mechanism, the accurate lateral positioning of the main frame 200 can be easily achieved, which is conducive to ensuring the subsequent welding accuracy and improving product quality.

[0057] Specifically, Figure 1-4 As shown, the clamping and fixing mechanism also includes a bottom clamping and fixing mechanism 450, which abuts against the upper surface of the bottom cross beam 210 of the main frame 200. The bottom clamping and fixing mechanism 450 is installed on the fixed bottom frame 100. The bottom clamping and fixing mechanism 450 is suitable for cooperating with the jacking drive 300 to clamp and fix the main frame 200.

[0058] In this embodiment, if Figure 1-4 As shown, the function of the bottom clamping and fixing mechanism 450 is to cooperate with the jacking drive 300 to clamp and fix the bottom crossbeam 210 of the main frame 200, and firmly position the main frame 200 on the fixed bottom frame 100. The clamping force of the bottom clamping and fixing mechanism 450 can be adjusted by feedback from the pressure sensor to avoid damage to the main frame 200. After the clamping and fixing is completed, subsequent welding and other operations are performed. By cooperating with the jacking drive 300, the bottom clamping and fixing mechanism 450 can firmly fix the main frame 200 with the adjusted inclination, prevent the main frame 200 from shifting, and ensure the accuracy of subsequent work.

[0059] Specifically, Figure 1-4 As shown, the pressing and fixing mechanism may be of the following structure:

[0060] Compression link 410, one end of the compression link 410 is hingedly mounted on the fixed bottom frame 100;

[0061] A pressing driving member 420, wherein the pressing driving member 420 is fixedly mounted on the fixed bottom frame 100;

[0062] A pressing block 430, wherein the middle position of the pressing block 430 is hinged to the pressing connecting rod 410, and one end of the pressing block 430 is hinged to the pressing driving member 420;

[0063] The clamping driving member 420 is suitable for driving the clamping block 430 to rotate at the hinge point with the clamping link 410 so that the other end of the clamping link 410 abuts against the upper surface of the main frame 200 .

[0064] In this embodiment, if Figure 1-4As shown, the function of the clamping and fixing mechanism is to clamp and fix the main frame 200 vertically downward. The clamping and fixing mechanism adopts a combination of a clamping connecting rod 410 and a clamping block 430. When the clamping driving member 420 is working, it drives the clamping block 430 to rotate around the hinge with the clamping connecting rod 410, so that the other free end of the clamping block 430 produces a pressing and pressing action, and finally abuts against the upper surface of the top surface of the main frame 200, exerting a vertical downward clamping force on the main frame 200, and fixing it on the fixed bottom frame 100. The clamping driving member 420 can also select a motor, a cylinder or a spiral clamping mechanism, and the clamping force can be set to avoid damage to the main frame 200.

[0065] Specifically, Figure 1-4 As shown, the longitudinal limiting mechanism may have the following structure:

[0066] A sliding assembly, the sliding assembly is mounted on the fixed bottom frame 100;

[0067] A lateral limit block 510, wherein the lateral limit block 510 is installed on the sliding assembly;

[0068] The main frame 200 is provided with an oblique beam 220;

[0069] The lateral limit block 510 abuts against the lateral side of the oblique beam 220 of the main frame 200;

[0070] The pushing component is connected to the sliding component, and the pushing component is suitable for pushing the sliding component to move.

[0071] In this embodiment, if Figure 1-4 As shown, the function of the longitudinal limiting mechanism is to longitudinally position the main frame 200.

[0072] The main frame 200 is provided with oblique beams 220 on both sides. The sliding assembly drives the lateral limit block 510 to slide, so that the lateral limit block 510 moves on the fixed bottom frame 100 and abuts against the oblique beam 220 on the side of the main frame 200, thereby realizing the longitudinal positioning of the main frame 200. The pushing assembly is used to drive the sliding assembly and the lateral limit block 510 to slide, and a screw screw, rack gear and other mechanisms can also be used. The driving direction and distance of the pushing assembly can be precisely controlled to adjust the abutting position of the lateral limit block 510 to achieve fine adjustment of the longitudinal position of the main frame 200.

[0073] Specifically, Figure 1 and 3 -4, the longitudinal limiting mechanism also includes:

[0074] A lateral abutment driving member 500, wherein the lateral abutment driving member 500 is mounted on the fixed bottom frame 100;

[0075] The lateral abutment driving member 500 is adapted to cooperate with the lateral limiting block 510 to fix the main frame 200 .

[0076] In this embodiment, if Figure 1-4 As shown, the lateral abutment driving member 500 may also use a spiral clamping mechanism, etc., and control its clamping force to avoid damage to the main frame 200.

[0077] Specifically, Figure 1-2 and Figure 4-5 As shown, the sliding component can be structured as follows:

[0078] A guide rail 610, wherein the guide rail 610 is longitudinally mounted on the fixed bottom frame 100;

[0079] The slider 620 is slidably disposed on the guide rail 610 and is connected to a pushing assembly. The pushing assembly is suitable for driving the slider 620 to slide longitudinally along the guide rail 610.

[0080] In this embodiment, if Figure 1-5 As shown, the use of a guide rail slider can ensure the accuracy and reliability of sliding and avoid position deviation. At the same time, it is also convenient to realize the structural design of the push component to drive the slider 620 to slide. Through the operation of the sliding component, the longitudinal position of the lateral limit block 510 can be flexibly and smoothly adjusted, thereby accurately realizing the longitudinal positioning of the main frame 200.

[0081] Specifically, Figure 1 and Figure 3-5 As shown, the pressing and fixing mechanism also includes a side pressing and fixing mechanism 700 , which is installed on the slider 620 . The side pressing and fixing mechanism 700 is suitable for pressing the upper surfaces of the two longitudinal sides of the main frame 200 .

[0082] In this embodiment, if Figure 1-5As shown, the side pressing and fixing mechanism 700 is used to press and fix the surfaces of the main frame 200 on both sides in the longitudinal direction. When the slider 620 moves the lateral limit block 510 to the position through the sliding assembly so that it abuts against the inclined beam 220 on the side of the main frame 200, the side pressing and fixing mechanism 700 is started. The side pressing and fixing mechanism 700 applies a pressing force to the upper surfaces of the two sides in the longitudinal direction of the main frame 200 to fix the main frame 200 on the fixed bottom frame 100. The side pressing and fixing mechanism 700 can also be in the form of a spiral pressing mechanism. The side pressing and fixing mechanism 700 is used in conjunction with the lateral limit block 510 to not only realize the longitudinal positioning of the main frame 200, but also to press and fix its two sides in the longitudinal direction to prevent the main frame 200 from being displaced on the fixed bottom frame 100, thereby ensuring the accuracy of the subsequent process. Its pressing force can be set according to the material properties and size of the main frame 200 to avoid damage to it.

[0083] Specifically, Figure 4 and Figure 2 As shown, the lateral abutment driving member 500, the pressing driving member 420 and the lifting driving member 300 are all cylinders.

[0084] In this embodiment, since most of the driving parts use cylinders, they can be connected through the air circuit during use, and one-key pin lifting positioning and one-key clamping can be disabled.

[0085] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
