Abstract
Description
Technical Field
[0001] This invention relates to the field of welding station technology, specifically a welding station for processing automotive seat parts. Background Technology
[0002] The frame structure of a car seat is typically assembled from various sheet metal stamping parts (such as U-shaped frames) and tubular components (such as side bars) through welding. The quality and precision of the weld joints directly determine the strength, safety, and dimensional consistency of the seat assembly. Welding these non-standard parts still presents some shortcomings in practical use: 1. To ensure the stability of irregular workpieces during welding, traditional tooling commonly uses multiple independently driven pneumatic or hydraulic cylinders to clamp the workpiece at multiple points. Because it is difficult for each drive unit to achieve absolute synchronization, there is a slight timing difference (i.e., "hysteresis"), resulting in the clamping force not being applied evenly and simultaneously to the workpiece. This asynchronous clamping easily causes the workpiece (such as a U-shaped frame) to experience slight displacement or warping during the clamping stage, severely affecting welding quality. 2. The butt welding of the U-shaped frame and the side rod requires extremely high positional accuracy of the mating end faces. Existing technology relies entirely on the absolute positioning accuracy of the initial adjustment between the clamping mechanisms. However, mechanical wear caused by long-term operation of the equipment, stress relaxation of fasteners, or dimensional tolerances of different batches of workpieces will accumulate into systematic errors, causing the preset mating position to shift. The machine must be stopped and manually recalibrated, which seriously disrupts the production cycle and affects the continuity of automated production. Summary of the Invention
[0003] The purpose of this invention is to provide a welding station for processing automotive seat parts, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a welding table for processing automotive seat parts, comprising a worktable, wherein a first fixing mechanism is installed on the worktable, the first fixing mechanism being used to clamp and fix a U-shaped frame, and a second fixing mechanism is symmetrically arranged on the left and right sides of the front of the first fixing mechanism, the second fixing mechanism being used to clamp and fix the side rod. A drive mechanism is used to drive the second fixed mechanism to move and achieve automatic alignment between the side rod and the U-shaped frame. The drive mechanism is mounted on the workbench. The floating adjustment mechanism utilizes floating adjustment to achieve precise docking between the side rod and the U-shaped frame, and the self-locking mechanism ensures the accuracy of the docking position. The floating adjustment mechanism is interconnected with the drive mechanism, and a second fixing mechanism is installed on the floating adjustment mechanism.
[0005] Preferably, the first fixing mechanism includes a first cylinder fixed on the workbench, and a movable frame is fixed to the output end of the first cylinder. The movable frame is slidably connected to the first vertical rod. Meanwhile, the first vertical rod is fixed on the workbench. The movable frame can be driven to move up and down by the first cylinder. With the sliding guide effect between the movable frame and the first vertical rod, the stability of the movable frame movement can be ensured.
[0006] Preferably, a first inclined block is fixed on the movable frame, and the first inclined block is slidably connected to the first slide rod. The first slide rod is fixed to the first drive rod, and the first drive rod is slidably connected to the first support seat. The first support seat is fixed on the worktable, and a first movable clamping plate is also fixed on the first drive rod. The first movable clamping plate cooperates with the first fixed clamping plate fixed on the first support seat to clamp and fix the U-shaped frame. At the same time, inclined blocks are symmetrically fixed on the two first support seats on the front side. By moving the movable frame, the first inclined block can be moved. With the sliding action between the first inclined block and the first slide rod and the sliding action between the first drive rod and the first support seat, the distance between the first movable clamping plate and the first fixed clamping plate can be adjusted to achieve clamping and fixing of U-shaped frames of different sizes.
[0007] Preferably, the driving mechanism includes a second cylinder fixed on the worktable, and a disc is fixed to the output end of the second cylinder. A square rod is fixed on the disc, and the square rod is slidably connected to the connecting rod. A first spring is fixed between the connecting rod and the disc. The second cylinder can provide a basic force for the movement of the disc and the connecting rod, thereby providing a basic guarantee for the normal operation of the device.
[0008] Preferably, the connecting rod is symmetrically fixed with transplanting platforms on the left and right, and a slider is fixed on the lower end face of the transplanting platform. The slider and the guide rail are slidably connected. At the same time, the guide rail is fixed on the worktable. When the connecting rod drives the transplanting platform to move, the sliding guidance between the slider and the guide rail can ensure the stability of the transplanting platform's movement.
[0009] Preferably, the floating adjustment mechanism includes a floating platform disposed above the transplanting platform, and movable blocks are symmetrically fixed to the front and back of the lower end face of the floating platform. The movable blocks are slidably connected to the guide rod, and the guide rod is fixed to the transplanting platform. A second spring is fixed between the movable blocks and the transplanting platform. Through the sliding action between the movable blocks and the guide rod, the left and right positions of the floating platform can be finely adjusted, thereby providing a basic guarantee for the precise docking of the side rod and the U-shaped frame, and thus ensuring the welding quality.
[0010] Preferably, a rack is also fixed on the movable block, and the rack and the locking block form an engaging connection. The locking blocks are symmetrically fixed on the fixed rod, and the fixed rod and the square rod are fixedly connected. Through the above structure, the position of the movable block can be self-locked, thereby realizing the position self-locking of the floating platform and ensuring the stability of the device.
[0011] Preferably, the second fixing mechanism includes a third cylinder fixed on the floating platform, and a mounting plate is fixed to the output end of the third cylinder. The mounting plate and the second vertical rod are slidably connected. The second vertical rod is symmetrically fixed on the floating platform. Through the action of the third cylinder, a basic force can be provided for the movement of the mounting plate. Combined with the sliding guide effect between the mounting plate and the second vertical rod, the stability of the movement of the mounting plate can be ensured.
[0012] Preferably, the mounting plate is symmetrically fixed with second inclined slot blocks at the front and rear, and the second inclined slot blocks are slidably connected to the second slide rod. The second slide rod is fixed to the second drive rod, and the second drive rod is slidably connected to the second support seat fixed on the floating platform. The second drive rod is fixed to the second movable clamping plate, and the second movable clamping plate cooperates with the second fixed clamping plate fixed on the second support seat to achieve the clamping and fixing function of the side rod. The second support seat is flush with the height of the first support seat. The mounting plate drives the second inclined slot blocks to move. Combined with the sliding action between the second inclined slot blocks and the second slide rod and the sliding action between the second slide rod and the second support seat, the distance between the second movable clamping plate and the second fixed clamping plate can be adjusted, thereby adapting to the clamping and fixing function of side rods of different sizes.
[0013] Preferably, the second support base is also symmetrically fixed with brackets on the left and right, and the brackets are connected to rollers by bearings. The minimum distance between the two rollers is equal to the maximum distance between the two inclined blocks. At the same time, a positioning plate is fixed on the front second support base. The positioning plate contacts the side rod to achieve positioning. Through the rolling action of the rollers and the inclined blocks, a basic force can be provided to realize the automatic correction of the side rod, ensuring the normal operation of the device.
[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The welding table for processing automotive seat parts is driven by a cylinder. With the help of the inclined slot block and the slide rod transmission, the multi-point clamping of the first and second fixing mechanisms can be synchronously realized to clamp and fix the workpiece, thereby ensuring the absolute synchronicity of the clamping point actions. This completely eliminates the stress unevenness and workpiece warping caused by the lag of multiple drivers, and provides a guarantee for subsequent high-precision welding. 2. The welding table for processing automotive seat parts has an adaptive alignment system consisting of a drive mechanism and a floating adjustment mechanism. When the side rod is pushed towards the U-shaped frame, if there is a lateral deviation between the two preset docking positions due to accumulated errors, the roller installed on the second support will contact the inclined surface of the inclined block on the first support. Under the guidance of the inclined surface, the entire floating table and the side rod on it will be forced to produce lateral adaptive floating until the roller falls into the flat surface of the inclined block to complete the positioning. This process realizes the precise alignment between workpieces, enabling the welding table to compensate for tooling wear and basic positioning errors, and better meet the requirements of precise welding. 3. The welding table for processing automotive seat parts utilizes a flexible connection between the connecting rod and the square rod in the drive mechanism via a first spring to form a buffer drive link. This not only absorbs the impact at the moment of workpiece docking, protecting the workpiece and the mechanism, but also allows the drive cylinder to continue providing stable propulsion after docking. This force is converted into a continuous clamping force on the docking end face through the spring, ensuring tight contact at the welding interface. After docking, the floating table can be self-locked by a mechanical self-locking mechanism composed of a fixed rod, a locking tooth block, and a rack, thereby ensuring that the weld is formed in an absolutely stable environment and greatly improving the reliability and consistency of welding quality.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figures 1-7 The present invention provides a technical solution: a welding table for processing automotive seat parts, including a worktable 1, a first fixing mechanism 2 installed on the worktable 1, the first fixing mechanism 2 being used to clamp and fix a U-shaped frame 3, and a second fixing mechanism 6 symmetrically arranged on the left and right sides of the front of the first fixing mechanism 2, the second fixing mechanism 6 being used to clamp and fix a side rod 7. The drive mechanism 4 is used to drive the second fixing mechanism 6 to move and realize the automatic alignment of the side rod 7 and the U-shaped frame 3. The drive mechanism 4 is installed on the workbench 1. The floating adjustment mechanism 5 uses floating adjustment to achieve precise docking between the side rod 7 and the U-shaped frame 3, and with the help of self-locking, it can ensure the accuracy of the docking position. The floating adjustment mechanism 5 is connected to the drive mechanism 4, and a second fixing mechanism 6 is installed on the floating adjustment mechanism 5.
[0019] The first fixing mechanism 2 includes a first cylinder 201 fixed on the workbench 1, and a movable frame 202 fixed at the output end of the first cylinder 201. The movable frame 202 is slidably connected to the first vertical rod 203, and the first vertical rod 203 is fixed on the workbench 1. A first inclined slot block 204 is fixed on the movable frame 202, and the first inclined slot block 204 is slidably connected to the first slide rod 205. The first slide rod 205 is fixed on the first drive rod 206, and the first drive rod 206 is slidably connected to the first support seat 207. The first support seat 207 is fixed on the workbench 1, and a first movable clamping plate 208 is also fixed on the first drive rod 206. The first movable clamping plate 208 cooperates with the first fixed clamping plate 209 fixed on the first support seat 207 to clamp and fix the U-shaped frame 3. At the same time, inclined blocks 210 are symmetrically fixed on the two first support seats 207 on the front side. When using a welding station for processing automotive seat parts, such as Figure 1 As shown in Figure 7, the U-shaped frame 3 is first placed on the first support base 207. At this time, the outer edge of the U-shaped frame 3 can be positioned by the first fixed clamps 209 on the multiple first support bases 207. Then, the first cylinder 201 is extended by controlling it, thereby driving the movable frame 202 to move upward. With the sliding guide between the movable frame 202 and the first vertical rod 203, the stability of the movement of the movable frame 202 can be ensured. When the movable frame 202 moves upward, it can simultaneously drive the first inclined groove block 204 to move upward. The sliding between the inclined groove on the first inclined groove block 204 and the first sliding rod 205... The function is to move the first drive rod 206 and the first movable clamping plate 208 toward the first fixed clamping plate 209 until the first movable clamping plate 208 contacts the inner edge of the U-shaped frame 3, thereby achieving the clamping and fixing function of the U-shaped frame 3. Moreover, the entire clamping mechanism is driven by a single first cylinder 201, which can realize the cooperation of multiple first movable clamping plates 208 and multiple first fixed clamping plates 209 to achieve multi-point simultaneous clamping and fixing of the U-shaped frame 3. This effectively avoids the problems of displacement and warping of the U-shaped frame 3 caused by the lag of the traditional clamping mechanism driven by multiple cylinders, and better meets the clamping and fixing requirements of the U-shaped frame 3. The second fixing mechanism 6 includes a third cylinder 601 fixed on the floating platform 501, and a mounting plate 602 fixed to the output end of the third cylinder 601. The mounting plate 602 is slidably connected to the second vertical rod 603, and the second vertical rod 603 is symmetrically fixed to the floating platform 501. A second inclined groove block 604 is symmetrically fixed to the mounting plate 602, and the second inclined groove block 604 is slidably connected to the second sliding rod 605. The second sliding rod 605 is fixed to the second drive rod 606, and the second drive rod 606 is slidably connected to the second support seat 607 fixed on the floating platform 501. The movable rod 606 is fixed to the second movable clamping plate 608, and the second movable clamping plate 608 cooperates with the second fixed clamping plate 609 fixed on the second support base 607 to achieve the clamping and fixing function of the side rod 7. The second support base 607 is flush with the height of the first support base 207. The second support base 607 is also symmetrically fixed with brackets 610 on the left and right, and the brackets 610 are connected to rollers 611 by bearings. The minimum distance between the two rollers 611 is equal to the maximum distance between the two inclined blocks 210. At the same time, a positioning plate 612 is fixed on the front second support base 607. The positioning plate 612 contacts the side rod 7 to achieve positioning. After the U-shaped frame 3 is fixed, as follows Figures 1-7 As shown, the side rod 7 is then placed on the second support base 607, and the side rod 7 contacts the second fixed clamping plate 609 for positioning. The front end of the side rod 7 also contacts the positioning plate 612 for positioning. Then, by controlling the extension of the third cylinder 601, the mounting plate 602 can be moved upwards. Combined with the sliding guide action between the mounting plate 602 and the second vertical rod 603, the stability of the mounting plate 602's movement is ensured. Simultaneously, as the mounting plate 602 moves, the second inclined groove block 604 moves as well. The second inclined groove block 604... The sliding action between the inclined groove and the second slide rod 605 allows the second drive rod 606 and the second movable clamping plate 608 to move closer to the second fixed clamping plate 609 until the second movable clamping plate 608 contacts the side rod 7, thus achieving the clamping and fixing effect of the side rod 7. The clamping and fixing of the side rod 7 is driven by a single third cylinder 601, thereby achieving multi-point synchronous clamping of the side rod 7. This avoids the problems of lag caused by the side rod 7 due to the traditional clamping mechanism driven by multiple cylinders, and better meets the clamping and fixing requirements of the side rod 7. The drive mechanism 4 includes a second cylinder 401 fixed on the worktable 1, and a disc 402 fixed to the output end of the second cylinder 401. A square rod 403 is fixed on the disc 402, and the square rod 403 is slidably connected to the connecting rod 404. A first spring 405 is fixed between the connecting rod 404 and the disc 402. A transplanting platform 406 is symmetrically fixed on the connecting rod 404, and a slider 407 is fixed to the lower end face of the transplanting platform 406. The slider 407 is slidably connected to the guide rail 408, and the guide rail 408 is fixed on the worktable 1. The floating adjustment mechanism 5 includes... A floating platform 501 is set above the transplanting platform 406, and movable blocks 502 are symmetrically fixed to the front and back of the lower end of the floating platform 501. The movable blocks 502 are slidably connected to the guide rod 503, and the guide rod 503 is fixed on the transplanting platform 406. A second spring 504 is fixed between the movable blocks 502 and the transplanting platform 406. A rack 505 is also fixed on the movable blocks 502, and the rack 505 is engaged with the locking block 506. The locking block 506 is symmetrically fixed on the fixed rod 507, and the fixed rod 507 is fixedly connected to the square rod 403. After the U-shaped frame 3 and the side rod 7 are fixed, as follows Figures 1-7 As shown, by controlling the extension of the second cylinder 401, the disc 402, connecting rod 404, first spring 405, transplanting platform 406, second fixing mechanism 6 and side rod 7 can be driven to move closer to the U-shaped frame 3. With the sliding guidance between the slider 407 and the guide rail 408, the stability of the device movement can be ensured. If there is no deviation between the welding end of the U-shaped frame 3 and the welding end of the side rod 7, that is, there is no deviation between the positions of the first support 207 and the second support 607, the welding end of the side rod 7 and the welding end of the U-shaped frame 3 can be properly connected so that the subsequent welding can proceed normally. At this time, the roller 611 does not contact the inclined surface of the inclined block 210. If there is a deviation between the welding end of the U-shaped frame 3 and the welding end of the side rod 7, that is, if the positions of the first support seat 207 and the second support seat 607 are deviated due to loose bolts or mechanical wear, when the welding end of the side rod 7 is connected to the welding end of the U-shaped frame 3, due to the positional deviation between the first support seat 207 and the second support seat 607, the roller 611 rolls on the inclined surface of the inclined block 210, which can generate a force on the first support seat 207, thereby causing the floating platform 501 to move under force. With the sliding guidance between the moving block 502 and the guide rod 503, the stability of the movement of the floating platform 501 can be ensured. Through the movement of the floating platform 501, the positional correction of the second support seat 607 and the side rod 7 can be achieved until the roller 611 rolls to contact the plane of the inclined block 210, thereby completing the correction of the side rod 7. At this time, the welding end of the side rod 7 can continue to move towards the welding end of the U-shaped frame 3 to achieve precise connection. When the welding end of the side rod 7 contacts the welding end of the U-shaped frame 3, the second cylinder 401 continues to extend, allowing the disc 402 and the square rod 403 to move relative to the connecting rod 404. At this time, the first spring 405 contracts under force. Through the movement of the square rod 403, the fixed rod 507 and the locking block 506 can be moved synchronously until the locking block 506 engages with the rack 505 to achieve a locking effect, thereby locking the position of the floating table 501 and ensuring the stability of the device during subsequent welding. Furthermore, through the elastic action of the first spring 405, a certain clamping force can be provided to the welding end of the side rod 7 and the welding end of the U-shaped frame 3, ensuring close contact between the welding end of the side rod 7 and the welding end of the U-shaped frame 3, and ensuring welding quality.
