There are many parts, and the dimensional accuracy requirements after the overall welding are very high, so the problem of poor welding of the support product often occurs. Especially the angle block welded on the side of the side plate. The position of the angle block after welding determines the backrest angle of the final seat product after installation.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0028] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.
[0029] like Figure 8 and Fig. 9As shown, the automobile seat shaft provided by the embodiment of the present application includes a first support 510 and a second support 520 connected by a shaft, wherein the first support 510 is formed by arc welding of the bottom plate, the side plate 511, the block 512 and the reinforcing rib. The first support 510 has many parts, and the dimensional accuracy requirement after the overall welding is completed is very high, so the problem of poor welding of the finished product of the first support 510 often occurs. Especially the angle block 512 welded on the side of the side plate 511. The position of the angle block 512 after welding determines the backrest angle of the final seat product after installation. The angle block 512 is small in size and is welded around a thin sector, resulting in the existing positioning can only rely on the positioning of the surrounding profiling grooves. But this determines that there is no adjustment during welding. The angle block 512 is die-cast, and the sector curvature and the outer dimensions fluctuate greatly. If the size is small, it will shake when placed in the profiling groove, and it will not be placed in the profiling groove when the size is out of tolerance. If the dimensional accuracy of the profiled stopper is to be improved, further processing is required, which will cause a substantial increase in the cost of the small part of the angle stopper 512.
[0030] To this end, the present application provides a welding device for an angle stopper of a car seat shaft, which can accurately locate the welding position of the angle stopper 512 and effectively improve the welding accuracy of the angle stopper 512, wherein: Figure 7 It is a schematic diagram showing that the angle stopper 512 is correctly welded to the side plate 511 .
[0031] Reference Figures 1 to 3 The welding device of the automobile seat shaft angle block of the present application includes a clamping part 100, a positioning component and a first driving component, wherein the clamping part 100, the positioning component and the first driving component are all arranged on a workbench (not shown in the figure). Specifically, the clamping part 100 is fixed to the workbench by bolts, and the clamping part 100 is used to position and clamp the side plate 511. The positioning component is arranged relative to the clamping part 100, and the positioning component can slide linearly on the workbench. The positioning component includes an adjustment component 240, a positioning member 250 and a pre-tightening component. The positioning member 250 is fixed to the adjustment component 240. The adjustment component 240 is used to adjust the height of the positioning member 250 and adjust the position of the positioning member 250 parallel to the horizontal direction of the clamping part 100. The deviation of the positioned angle block 512 compared with the welding position on the side plate 511 can be adjusted relatively quickly through the adjustment component 240, and the pre-tightening component is used to press and position the angle block 512 placed on the positioning member 250 to facilitate subsequent welding. During welding, the first driving member drives the positioning component to move closer to or farther from the clamping portion 100, so as to facilitate welding and loading and unloading.
[0032] Compared with the existing method of positioning the angle block 512 by relying on the surrounding profiling grooves, the present application optimizes the positioning method of the angle block 512, making the adjustment and positioning of the angle block 512 more convenient. In specific use, the angle block 512 is preliminarily positioned by the positioning member 250, and a positioning reference is set on the positioning member 250. After the angle block 512 is placed, the angle block 512 on the positioning member 250 is pushed to the positioning reference by the pre-tightening component to complete the positioning of the angle block 512, and the positioning is convenient; after the positioning and clamping of the angle block 512 and the side plate 511 are completed, the first driving component drives the positioned angle block 512 to move to the preset welding position of the side plate 511. If the angle block 512 corresponds to the preset welding position, welding is directly performed. If it does not correspond, the height position and horizontal position of the angle block 512 are adjusted by the adjustment component. The optimized welding device can adapt to the angle block 512 with large dimensional fluctuations, and has sufficient adjustment space to solve the problem of inaccurate positioning. The welding position of the angle block can be accurately positioned through simple adjustment, effectively improving the welding accuracy of the angle block and the side panel.
[0033] In some embodiments, Figure 2 As shown, the positioning component includes a mounting seat 230, and the adjustment component 240 and the pre-tightening component are fixed to the mounting seat 230. The positioning member 250 extends above the pre-tightening component. Such a design can make the size of the entire welding device more compact and reduce the occupied space. Among them, the mounting seat 230 is slidably connected to the workbench through a guide rail slider structure 260, so that the mounting seat 230 can perform linear motion. The guide rail slider structure 260 includes a slide rail 262 and a slider 261 matched with the slide rail 262. The slide rail 262 is connected to the workbench through threads, and the mounting seat 230 is connected to the slider 261 through threads.
[0034] Further, the first driving assembly includes a second cylinder 211, a driving shaft of the second cylinder 211 is parallel to the sliding direction of the mounting seat 230, and the driving shaft is fixedly connected to the mounting seat 230 through a connecting member 212. The second cylinder 211 is connected to the mounting base 230 through the connecting member 212, so that the positioning member 250 can be driven to move closer to or away from the clamping portion 100 under the action of the second cylinder 211, so as to facilitate welding and material loading and unloading.
[0035] Further, such as Figure 2As shown, the adjustment assembly 240 includes a first adjustment member 241, a second adjustment member 242 and a third adjustment member 243. The first adjustment member 241 is vertically arranged on the mounting seat 230, and the second adjustment member 242 is inclined. The second adjustment member 242 is connected to the first adjustment member 241 by a thread. Specifically, the second adjustment member 242 is connected to the first adjustment member 241 by a bolt, and the number of gaskets arranged between the second adjustment member 242 and the first adjustment member 241 is 0 to 10. The third adjustment member 243 is connected to the second adjustment member 242 by a thread. Specifically, the third adjustment member 243 is connected to the second adjustment member 242 by a bolt, and the number of gaskets arranged between the third adjustment member 243 and the second adjustment member 242 is 0 to 10. The positioning member 250 is fixed to the third adjustment member 243. The vertical height of the positioning member 250 can be adjusted by adjusting the number of gaskets between the second adjusting member 242 and the first adjusting member 241, and the horizontal position of the positioning member 250 can be adjusted by adjusting the number of gaskets between the third adjusting member 243 and the second adjusting member 242, so as to quickly adjust the angle block 512 to the welding position opposite the side plate 511, and the overall adjustment is convenient.
[0036] Furthermore, the inclination angle of the side surface where the second adjusting member 242 and the first adjusting member 241 are in contact is 30° to 60°. In the embodiment of the present application, the inclination angle of the side surface where the second adjusting member 242 and the first adjusting member 241 are in contact is preferably 45°. The end surface of the second adjusting member 242 is perpendicular to the side surface, and the third adjusting member 243 is in contact with the end surface. With such a design, the vertical height of the positioning member 250 can be adjusted by adjusting the number of gaskets between the second adjusting member 242 and the first adjusting member 241, and the horizontal position of the positioning member 250 can be adjusted by adjusting the number of gaskets between the third adjusting member 243 and the second adjusting member 242.
[0037] In some embodiments, Figure 4 Character Figure 6 As shown, the positioning member 250 includes a groove 251 for placing the angle stop 512. The shape of the groove 251 is similar to the appearance of the angle stop 512, but the size of the groove 251 is larger than the size of the angle stop 512. The initial positioning of the angle stop 512 is achieved by the groove 251, wherein a reference block 252 is provided at the end of the groove 251, and the pre-tightening assembly is used to press the angle stop 512 located in the groove 251 against the reference block 252. When the angle stop 512 is pushed against the reference block 252, the angle stop 512 is completely positioned. At this time, when the side plate 511 is also positioned and clamped, the positioned angle stop 512 can be driven to move to the welding position of the side plate 511 by the first driving assembly. When the angle stop 512 is in contact with the side plate 511, the first driving assembly keeps the angle stop 512 in contact with the side plate 511, which is convenient for subsequent welding around.
[0038] In some embodiments, the pre-tightening assembly includes a first driving member 221 and a pre-tightening member 222, a reference block 252 is disposed at one end of the profile groove 251, and the first driving member 221 is used to drive the pre-tightening member 222 to enter the other end of the profile groove 251 to press against the angle stopper 512 located in the profile groove 251. The profile groove 251 provides preliminary positioning, and the positioning and pressing of the pre-tightening assembly and the reference block 252 are combined to achieve complete positioning of the angle stopper 512.
[0039] In a preferred embodiment, the first driving member 221 is a first cylinder, and the preload member 222 is fixed to the cylinder shaft of the first cylinder. Figure 6 As shown, the positioning member 250 is provided with a notch 253 connected to the profile groove 251, and the pre-tightening member 222 is provided with a pre-tightening block 223, and the notch 253 is located on the movement path of the pre-tightening block 223. When the angle block 512 needs to be pressed and positioned, the pre-tightening block 223 is driven from the notch 253 into the profile groove 251 to push against the angle block 512 by the first cylinder.
[0040] In some embodiments, in order to avoid empty welding, the positioning component further includes a sensor 270 , and the sensor 270 is used to sense the presence or absence of the angle stopper 512 in the groove 251 .
[0041] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
