Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a welding device for automotive seat side panels. Background Technology

[0002] In the automotive manufacturing industry, the production and assembly of car seats involves the precise connection of multiple components. Among them, the seat side panel is a key component that ensures the structural strength and passenger safety of the seat, and its welding quality directly affects the overall performance and service life of the seat. In traditional automotive seat side panel welding operations, manual positioning or simple tooling fixtures are often used for fixing. Manual positioning suffers from low accuracy and poor consistency. Operators rely solely on experience to adjust the side panel position, which can easily lead to welding deviations and affect the accuracy of subsequent assembly. At the same time, it is difficult to control the clamping force manually. Too loose a grip can cause the workpiece to shift during welding, while too tight a grip may cause the workpiece to deform, further reducing the product qualification rate. Utility Model Content

The manual positioning method has the problems of low accuracy and poor consistency. Operators adjust the position of the side panel based solely on experience, which can easily lead to welding deviations and affect the subsequent assembly accuracy. At the same time, it is difficult to control the manual clamping force. Too loose a grip will cause the workpiece to shift during the welding process, while too tight a grip may cause the workpiece to deform.

[0021] like Figures 1-3 As shown, it illustrates a welding device for a car seat side panel according to one embodiment of the present invention, comprising: A processing table 1 is provided with a positioning frame 2 on its upper surface; Adjust the positioning component 3, which is set on the upper surface of the processing table 1; Drive clamping assembly 4 is mounted on the processing table 1; The adjustment and positioning component 3 includes a sliding rail 3-1, which is set on the processing table 1. An adjustment plate 3-2 is set at the upper end of the sliding rail 3-1. An extension frame 3-3 is set on the upper surface of the adjustment plate 3-2.

A clamping piece 3-10 is set at the end of the clamping clip 3-9.

[0022] In some examples, the sliding rail 3-1 is fixedly installed on the processing table 1, and the adjusting plate 3-2 is set at the upper end of the sliding rail 3-1, which can slide along the sliding rail 3-1 to achieve preliminary position adjustment. An extension frame 3-3 is fixed on the upper end face of the adjusting plate 3-2, and a stabilizing frame 3-4 is installed on the side wall of the extension frame 3-3. The side wall of the stabilizing frame 3-4 is provided with a positioning protrusion 3-5 for preliminary positioning and limiting of the seat side guard. A reinforcing frame 3-6 is installed on the upper end face of the extension frame 3-3, and a push rod 3-7 is inserted through the reinforcing frame 3-6. The end of the push rod 3-7 is connected to a swing frame 3-8 through a pin. A clamping clamp 3-9 is installed on the side wall of the swing frame 3-8, and a clamping piece 3-10 is provided at the end of the clamping clamp 3-9. By swinging the swing frame 3-8, the clamping clamp 3-9 and the clamping piece 3-10 can be driven to move, thereby achieving clamping and positioning adjustment of the seat side guard and ensuring positional accuracy during welding.

[0023] refer to Figure 1 and Figure 3 In some embodiments, a linkage frame 3-11 is provided on opposite sides of the swing frame 3-8, and the linkage frame 3-11 is connected to the reinforcing frame 3-6 by a pin. A push cylinder 3-12 is provided on the side wall of the push rod 3-7.

[0024] In some examples, the swing frame 3-8 is provided with a linkage frame 3-11 on both sides. The linkage frame 3-11 and the reinforcing frame 3-6 are connected by a pin. This structural design allows the push rod 3-7 to drive the swing frame 3-8 to swing around the connecting pin of the linkage frame 3-11 and the reinforcing frame 3-6 when it extends or retracts. The side wall of the push rod 3-7 is connected to a push cylinder 3-12. Under the action of the push cylinder 3-12, the push rod 3-7 can extend or retract along the reinforcing frame 3-6.

[0025] like Figures 1-3As shown, on the other hand, the present invention also provides a drive clamping assembly 4, including a drive cover 4-1, a lifting shaft 4-2 is provided inside the drive cover 4-1, a fixing frame 4-3 is provided at the upper end of the drive cover 4-1, a clamping claw 4-4 is connected to the inside of the fixing frame 4-3 by a pin, and the clamping claw 4-4 is connected to the lifting shaft 4-2 by a pin.

[0026] In some examples, the drive cover 4-1 is fixedly installed on the processing table 1. A fixed frame 4-3 is installed on the upper end of the drive cover 4-1. The inside of the fixed frame 4-3 is connected to the clamping claw 4-4 by a pin. The clamping claw 4-4 is also connected to the lifting shaft 4-2 by a pin. When the lifting shaft 4-2 rises and falls, it can drive the clamping claw 4-4 to swing around the connecting pin with the fixed frame 4-3 as the fulcrum.

[0027] refer to Figure 1 and Figure 3 In some embodiments, the side wall of the positioning frame 2 is provided with a positioning groove 4-5, and one end of the clamping claw 4-4 is embedded in the interior of the positioning groove 4-5.

[0028] In some examples, the side wall of the positioning frame 2 is provided with a positioning groove 4-5, and one end of the clamping claw 4-4 can be embedded in the interior of the positioning groove 4-5. By swinging the clamping claw 4-4, the seat side guard can be clamped and released. Under the action of the positioning groove 4-5, the stability and positional accuracy of the clamping are further guaranteed.

[0029] For example, such as Figure 1 As shown, the upper end face of the processing table 1 is provided with a positioning strip 5, and the lower end face of the adjustment plate 3-2 is provided with a sliding groove 6, with the positioning strip 5 embedded inside the sliding groove 6.

[0030] In some examples, the upper surface of the processing table 1 is also provided with a positioning strip 5, which cooperates with the sliding groove 6 opened on the lower surface of the adjustment plate 3-2 to provide guidance for the sliding of the adjustment plate 3-2.

[0031] For example, such as Figure 2 As shown, a drive cylinder 7 is installed inside the drive cover 4-1, and the drive cylinder 7 is connected to the lifting shaft 4-2.

[0032] In some examples, the drive housing 4-1 is equipped with a drive cylinder 7 and a lifting shaft 4-2. The drive cylinder 7 is connected to the lifting shaft 4-2. Under the drive of the drive cylinder 7, the lifting shaft 4-2 can move up and down within the drive housing 4-1.

[0033] For example, such as Figure 1 As shown, there are two positioning frames 2, which correspond to the positions of the drive cover 4-1 and the adjustment plate 3-2, respectively.

[0034] In some examples, two positioning frames 2 are fixedly installed on the upper surface of the processing table 1, corresponding to the positions of the drive cover 4-1 and the adjustment plate 3-2 respectively, for auxiliary positioning to ensure the accurate relative positions between the components.

[0035] For example, such as Figure 1 As shown, a force-bearing frame 8 is provided on the adjustment plate 3-2, and one end of the force-bearing frame 8 is connected to a position adjustment cylinder 9.

[0036] In some examples, a force-bearing frame 8 is installed on the adjusting plate 3-2, and one end of the force-bearing frame 8 is connected to a position adjusting cylinder 9. Through the extension and retraction movement of the position adjusting cylinder 9, the adjusting plate 3-2 can be moved precisely along the sliding track 3-1, thereby adjusting the position of the adjusting plate 3-2.

[0037] In actual operation, the car seat side panel is placed on the processing table 1. The position of the positioning component 3 is adjusted by adjusting the cylinder 9 to move the adjusting plate 3-2, initially adjusting the position of the seat side panel. Then, the cylinder 3-12 is pushed to drive the push rod 3-7 to extend and retract, causing the swing frame 3-8 to swing, so that the clamping plate 3-10 initially clamps and positions the seat side panel. Next, the drive cylinder 7 of the clamping component 4 drives the lifting shaft 4-2 to rise and fall, causing the clamping claw 4-4 to swing, with one end embedded in the positioning groove 4-5 of the positioning frame 2, to firmly clamp the seat side panel. After that, the welding operation can be performed. After welding is completed, all components are reset and the welded seat side panel is removed.

[0038] During operation, the car seat side panel welding device works on the principle of multi-component collaborative positioning and clamping. Through the precise movement of the mechanical structure, it achieves the positioning, adjustment, and stable clamping of the car seat side panel, providing a stable and reliable operating basis for the welding process. The specific workflow is as follows: 1. Initial placement and basic positioning The car seat side panel to be welded is placed on the processing table 1. The positioning frame 2 at the upper end of the processing table 1 contacts the side panel workpiece through the positioning protrusions 3-5 on its side wall to achieve initial position limitation and prevent large displacement of the workpiece during placement. At the same time, the two positioning frames 2 correspond to the positions of the drive clamping component 4 and the adjustment positioning component 3, respectively, to provide a reference for subsequent precise operation.

[0039] 2. Adjust the position of positioning component 3 The adjustment plate 3-2 can slide along the sliding track 3-1 on the processing table 1 (in conjunction with the guiding effect of the positioning bar 5 and the sliding groove 6). By extending and retracting the position adjustment cylinder 9, the force frame 8 is pushed, which drives the adjustment plate 3-2 to move as a whole, so as to achieve coarse adjustment of the workpiece in the horizontal direction and ensure that the workpiece is aligned with the welding station.

[0040] When fine adjustment of the workpiece angle or local position is required, the cylinder 3-12 drives the push rod 3-7 to extend and retract along the reinforcing frame 3-6. Through the pin shaft transmission, the swing frame 3-8 swings with the connecting frame 3-11 as the fulcrum. The movement of the swing frame 3-8 is transmitted to the clamping clamp 3-9 and the clamping plate 3-10, so that the clamping plate 3-10 fits against the workpiece surface and applies appropriate pressure, thus completing the fine adjustment of the workpiece angle and local positioning, ensuring the precise alignment of the welding surface.

[0041] 3. Stable clamping of drive clamping component 4 The drive cylinder 7 inside the drive cover 4-1 drives the lifting shaft 4-2 to move up and down. Through the pin connection structure, the movement of the lifting shaft 4-2 is converted into the swing of the clamping claw 4-4 (with the pin on the fixed frame 4-3 as the fulcrum).

[0042] One end of the clamping claw 4-4 is embedded in the positioning groove 4-5 of the positioning frame 2. When the clamping claw 4-4 swings, its other end is in close contact with the surface of the workpiece. Together with the clamping piece 3-10 of the positioning component 3, it forms a multi-directional clamping force to firmly fix the workpiece in the preset position and prevent the workpiece from shifting due to vibration or force during the welding process.

[0043] 4. Welding operations and resetting Once the workpiece is precisely positioned and securely clamped, external welding equipment (such as a robotic arm or welding torch) performs welding operations on the side of the workpiece. After welding is completed, each power component (push cylinder 3-12, drive cylinder 7, and position adjustment cylinder 9) moves in reverse, causing the clamping plates 3-10 and clamping claws 4-4 to release the workpiece. The adjustment plate 3-2 resets, and the operator can then remove the welded workpiece, completing one work cycle.

[0044] The entire process combines mechanical transmission with pneumatic / hydraulic drive to automate the workpiece from initial positioning to precise adjustment and then to stable clamping, ensuring the consistency and stability of the workpiece position during welding, thereby improving welding quality and production efficiency.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
