Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, specifically a multi-station synchronous laser welding device for an automotive seat adjuster. Background Technology

[0002] A car seat adjuster typically consists of a backrest connecting plate, a seat connecting plate, a core component, a handwheel or adjustment handle, and a return spring. Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The laser beam is focused on the welding area, causing the material to rapidly absorb the laser energy, resulting in a sharp rise in temperature to the material's melting point or even boiling point, thus melting and fusing the materials together. In the welding of car seat adjusters, high-quality welding between different components is achieved by precisely controlling laser parameters such as power, pulse frequency, and pulse width.

[0003] When using existing multi-station synchronous laser welding equipment, multiple workpieces on the worktable surface are usually clamped synchronously through a linkage structure. However, the number of laser welding heads is often less than the number of workpieces. Moving the workpieces by rotating the worktable increases the efficiency of limiting the workpieces, but it is not convenient to remove the processed workpieces in a timely manner, which reduces the practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station synchronous laser welding device for automotive seat adjusters, in order to solve the problem mentioned in the background art that the workpiece is moved by the rotation of the worktable. Although this increases the efficiency of limiting the workpiece, it is not convenient to remove the processed workpiece in time, which reduces its practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station synchronous laser welding device for an automotive seat adjuster, comprising a worktable with a support frame on its side, a laser welding head fixedly mounted on the upper end of the support frame, a limit bracket fixedly connected to the upper surface of the worktable, an adjusting gear throughly mounted on the surface of the limit bracket, a limit slot on the lower surface of the worktable, an opening on the upper surface of the worktable, a linkage gear on the inner wall of the opening, a transmission screw fixedly connected to one end of the shaft of the linkage gear, a guide slider mounted on the outer surface of one end of the transmission screw, a first clamping plate mounted on the inner wall of the limit slot, a second clamping plate mounted on the inner wall of the limit slot, a positioning slider fixedly connected to one end of the second clamping plate, and a positioning mechanism on the surface of the worktable, which locks the positioning slider by locking a locking block and unlocks it by pressing an unlocking slide column to lower the locking block.

[0006] Preferably, the opening of the workbench is correspondingly provided with the limiting bracket, and the limiting bracket and the adjusting gear are rotatably connected.

[0007] By adopting the above technical solution, the opening and the limiting bracket are set in a corresponding manner, so that the rotation of the adjusting gear can accurately drive the movement of the related structure. The adjusting gear and the limiting bracket are rotatably connected, providing a basis for subsequent power transmission, ensuring that the rotation of the adjusting gear can be effectively transmitted to other components, and ensuring the accuracy and stability of the entire device operation.

[0008] Preferably, the limiting slot is arranged in a circular array, the linkage gear and the adjusting gear are meshed, and the linkage gear and the worktable are rotatably connected.

[0009] By adopting the above technical solution, the circumferential array of limiting slots, in conjunction with the meshing of the linkage gear and the adjusting gear, can realize synchronous movement of multiple workstations. When the adjusting gear rotates, it drives the linkage gear to rotate, thereby causing the components in the limiting slots of the circumferential array to move synchronously. Multiple car seat adjusters can be processed at the same time, improving processing efficiency.

[0010] Preferably, the transmission screw and the guide slider are threadedly connected, and the guide slider and the worktable are slidably connected.

[0011] By adopting the above technical solution, the threaded connection between the transmission screw and the guide slider can convert rotation into precise linear displacement. By controlling the rotation angle of the transmission screw, the movement distance of the guide slider can be precisely controlled, thereby accurately adjusting the position of the connected components and meeting the requirements for workpiece position accuracy during the welding of automotive seat adjusters.

[0012] Preferably, one end of the guide slider penetrates the inner wall of the limiting slot, the limiting slot and the first clamping plate are slidably connected, and the first clamping plate is fixedly connected to one end of the guide slider.

[0013] By adopting the above technical solution, the guide slider passes through the limiting slot and is fixedly connected to the first clamping plate, so that the movement of the guide slider can directly drive the movement of the first clamping plate. When the guide slider moves under the action of the transmission screw, the first clamping plate moves synchronously, realizing the clamping or loosening operation of the workpiece and ensuring the coordination of the movement between the components.

[0014] Preferably, the positioning mechanism includes an unlocking slide column, which is installed through the upper surface of the worktable, and a locking block is fixedly connected to the lower surface of the unlocking slide column.

[0015] By adopting the above technical solution, the operator can directly control the action of the locking block by operating the unlocking slide column on the worktable surface. Simply pressing the unlocking slide column can unlock the positioning slider, which is convenient and quick and improves the efficiency of workpiece loading and unloading.

[0016] Preferably, the unlocking slide column is slidably connected to the worktable, the locking block is slidably connected to the worktable, and a spring is connected between the locking block and the worktable. The locking block is engaged with the positioning slider.

[0017] By adopting the above technical solution, the presence of the spring enables the locking block to automatically engage with the positioning slider when no external force is applied, thereby achieving automatic positioning and locking of the workpiece and ensuring the stability of the workpiece during the welding process.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the multi-station synchronous laser welding device for the car seat adjuster:

[0019] 1. By setting the limiting slots in a circular array, and cooperating with the meshing connection of the linkage gear and the adjusting gear, multi-station synchronous operation can be realized. When the adjusting gear rotates, it drives the linkage gear, thereby making the relevant components of multiple stations move synchronously. It can process multiple car seat adjusters at the same time, which greatly shortens the processing time and improves production efficiency compared with traditional devices.

[0020] 2. By connecting the transmission screw and the guide slider via a threaded connection, rotation can be precisely converted into linear displacement, accurately controlling the movement distance of the guide slider, and thus precisely adjusting the position of the first clamping plate connected to it. The guide slider is slidably connected to the worktable, playing a stable guiding role and ensuring smooth movement. The limit slot is slidably connected to the first clamping plate, and the first clamping plate moves smoothly under the drive of the guide slider, which can reliably clamp the workpiece, avoid workpiece shaking during welding, and ensure welding quality.

[0021] 3. The unlocking slide column in the positioning mechanism passes through the surface of the worktable, and the lower surface of the slide column is connected to the locking block. Pressing the unlocking slide column can drive the locking block to descend, releasing the lock on the positioning slider, making it easy to remove the processed workpiece. The locking block is connected to the worktable by a spring. When there is no external force, the locking block can automatically engage with the positioning slider to achieve automatic positioning and locking. The operation is simple and flexible, meeting the production needs of frequent loading and unloading of workpieces. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a multi-station synchronous laser welding device for an automotive seat adjuster, including a worktable 1, a support frame 2, a laser welding head 3, a limiting bracket 4, an adjusting gear 5, a limiting slot 6, a linkage gear 7, a transmission screw 8, a guide slider 9, a first clamping plate 10, a second clamping plate 11, a positioning slider 12, an unlocking slide column 13, and a locking block 14. The worktable 1 has a support frame 2 on its side, and the laser welding head 3 is fixedly installed on the upper end of the support frame 2. The opening of the worktable 1 is correspondingly set with the limiting bracket 4. The limiting bracket 4 and the adjusting gear 5 are rotatably connected. First, when the adjusting gear 5 rotates, the linkage gear 7 meshes with the adjusting gear 5, and the linkage gear 7 is rotatably connected with the worktable 1. Therefore, the rotation of the adjusting gear 5 will drive the linkage gear 7 to rotate.

[0031] A limiting bracket 4 is fixedly connected to the upper surface of the workbench 1. An adjusting gear 5 is installed through the surface of the limiting bracket 4. A limiting slot 6 is opened on the lower surface of the workbench 1. An opening is provided on the upper surface of the workbench 1, and a linkage gear 7 is provided on the inner wall of the opening of the workbench 1. A transmission screw 8 is fixedly connected to one end of the shaft of the linkage gear 7. A guide slider 9 is installed on the outer surface of one end of the transmission screw 8. The limiting slots 6 are arranged in a circumferential array. The linkage gear 7 and the adjusting gear 5 are meshed. The linkage gear 7 and the workbench 1 are rotatably connected. The transmission screw 8 and the guide slider 9 are threadedly connected. The guide slider 9 and the workbench 1 are slidably connected. The limiting slots 6 are arranged in a circumferential array. This layout allows the linkage gear 7 to drive the components in multiple limiting slots 6 in the circumferential direction to move synchronously when it rotates. The transmission screw 8 and the guide slider 9 are threadedly connected. When the transmission screw 8 rotates, the guide slider 9 will generate linear displacement along the thread. When the guide slider 9 moves, it will drive the first clamping plate 10 to move synchronously. Since the limiting slot 6 and the first clamping plate 10 form a sliding connection, the first clamping plate 10 can move smoothly to achieve the clamping or loosening operation of the workpiece, ensuring the stability of the workpiece during the welding process.

[0032] A first clamping plate 10 is installed on the inner wall of the limiting slot 6, and a second clamping plate 11 is installed on the inner wall of the limiting slot 6. A positioning slider 12 is fixedly connected to one end of the second clamping plate 11, and one end of the guide slider 9 passes through the inner wall of the limiting slot 6. The limiting slot 6 and the first clamping plate 10 form a sliding connection, and the first clamping plate 10 is fixedly connected to one end of the guide slider 9. Under normal conditions, the spring force causes the locking block 14 to engage with the positioning slider 12, thereby achieving the positioning of the workpiece.

[0033] The workbench 1 is equipped with a positioning mechanism, which is fixed by locking the positioning slider 12 with the locking block 14 and unlocking it by pressing the unlocking slide column 13 to lower the locking block 14. The positioning mechanism includes the unlocking slide column 13, which is installed through the upper surface of the workbench 1. The lower surface of the unlocking slide column 13 is fixedly connected to the locking block 14. The unlocking slide column 13 and the workbench 1 are slidably connected. The locking block 14 and the workbench 1 are also slidably connected. A spring is connected between the locking block 14 and the workbench 1. The locking block 14 and the positioning slider 12 are engaged. When it is necessary to load or unload the workpiece, the operator presses the unlocking slide column 13 to overcome the spring force, causing the locking block 14 to lower and disengage from the positioning slider 12, thus unlocking the workpiece and facilitating loading and unloading.

[0034] Working principle: When using the multi-station synchronous laser welding device of this car seat adjuster, the adjusting gear 5 is rotated, which is rotatably connected to the limiting bracket 4 and adapted to the opening of the worktable 1 to ensure stable rotation. The adjusting gear 5 drives the linkage gear 7 to rotate, and the linkage gear 7 drives the transmission screw 8 to rotate. Through the threaded connection, the guide slider 9 slides along the worktable 1. The guide slider 9 passes through the limiting slot 6 and drives the first clamping plate 10 to move, thereby clamping or releasing the workpiece. During positioning, the spring causes the locking block 14 to engage with the positioning slider 12. When loading and unloading the workpiece, the unlocking slide column 13 is pressed, and the locking block 14 descends and disengages from the positioning slider 12 to complete the unlocking, which increases the overall practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
