Description

Technical Field

[0001] This utility model relates to automobile seats, specifically to a positioning and clamping fixture for welding seat side panel assemblies. Background Technology

[0002] Car seats can be categorized by shape (split seats, bench seats); by function (fixed, removable, adjustable); and by seating capacity (single, double, multi-seater). Based on performance, seats have evolved from early fixed seats to multi-functional power-adjustable seats, including air-cushioned seats, electric seats, stereo seats, recovery seats, and electronically adjustable seats. They can also be categorized by material (leather seats, cloth seats, etc.) and special-purpose seats such as child seats and racing seats. The seat side panel assembly is a crucial component of car seats, consisting of a seat buckle bracket, a cup holder bracket, and the side panel itself. The seat buckle bracket is located at the bottom of the side panel, and the cup holder bracket is located on the side wall and below it. Welding the connections between the seat buckle bracket, cup holder bracket, and side panel requires a welding fixture for the seat side panel assembly.

[0003] In existing technologies, the positioning and clamping fixtures used for welding seat side panel assemblies are inconvenient for positioning and clamping the seat buckle bracket, seat cup holder fixing bracket, and seat side panel within the seat side panel assembly. Furthermore, the connections are prone to loosening, affecting the stability of the welding and resulting in poor weld quality. Additionally, it is inconvenient to position and clamp the spot-welded nuts on the seat side panel; additional fixtures are required for positioning and clamping the spot-welded nuts before welding, increasing welding costs. Therefore, there is an urgent need for a positioning and clamping fixture for welding seat side panel assemblies to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning and clamping fixture for welding seat side plate assemblies, so as to solve the problems mentioned in the background technology. This utility model has a reasonable structure, convenient positioning and clamping, good anti-loosening effect, and saves welding costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a positioning and clamping fixture for welding seat edge plate assemblies, comprising:

[0006] The base plate has a positioning support block on one side of its top and a fixing support block on the other side of its top. The positioning support block and the fixing support block are respectively equipped with positioning pins and stop pins that match the through holes on the seat side plate in the seat side plate assembly. A pressure block is set above the positioning pin and a pressure plate is set above the stop pin. A pair of pressing components are set on the top of the base plate to drive the pressure block and the pressure plate to press and cooperate with the positioning support block and the fixing support block to clamp and fix the seat side plate in the seat side plate assembly.

[0007] The top of the base plate is provided with a first limiting plate and a second limiting plate. The top of the first limiting plate is provided with a first limiting groove, and the top of the second limiting plate is provided with a second limiting groove. The first limiting groove and the second limiting groove form a placement groove that matches the seat buckle bracket in the seat side panel assembly. The top of the second limiting plate is provided with a limiting pin that matches the first spot weld nut on the seat buckle bracket in the seat side panel assembly.

[0008] The top of the base plate is provided with a pair of positioning seats for supporting the seat cup holder fixing bracket in the seat side panel assembly. The top of each pair of positioning seats is provided with a positioning post that matches the positioning hole on the seat cup holder fixing bracket in the seat side panel assembly.

[0009] Furthermore, the pressing assembly includes a support seat disposed on the top of the base plate, and a vertical clamp is disposed on the top of the support seat;

[0010] The vertical clamps in a pair of pressing components are connected to the pressure block and the pressure plate, respectively.

[0011] Furthermore, the top of the base plate is provided with an extended support block located below the pressure block and used to support the seat side plate in the seat side plate assembly.

[0012] Furthermore, extension blocks are provided on both sides of the pressure plate. At the bottom of the extension blocks, there are pressure columns for pressing the second spot-welded nut on the seat side plate in the seat side plate assembly. At the top of the base plate, corresponding to the pressure column, there are spot-welded nut support blocks for supporting the second spot-welded nut on the seat side plate in the seat side plate assembly. At the top of the spot-welded nut support blocks, there are connecting pins that match the inner hole of the second spot-welded nut.

[0013] Furthermore, the pressure column includes a connecting column that extends through the interior of the extension block, and a pressure plate is provided at the bottom of the connecting column.

[0014] Furthermore, the bottom of the pressure block is provided with a through groove for avoiding the positioning pin, and the bottom of the pressure plate is provided with a relief groove for avoiding the stop pin.

[0015] According to this utility model, a positioning and clamping fixture for welding a seat side panel assembly is provided. The seat cup holder fixing bracket is positioned by connecting it to positioning pins on a pair of positioning seats through positioning holes. The positioning seats support the bottom of the seat cup holder fixing bracket, and the positioning pins and holes prevent the seat cup holder fixing bracket from moving laterally or longitudinally. Then, the seat buckle bracket is placed inside the placement groove, with its two sides respectively abutting against the inner walls of the first and second limiting grooves. Simultaneously, the inner hole of the first spot-welded nut on the seat buckle bracket connects to the limiting pin, preventing seat buckling. The bracket moves in the horizontal and vertical directions, and then the through holes on the seat side plate are connected to the positioning pins on the positioning support block and the stop pins on the fixed support block, respectively, to prevent the seat side plate from moving in the horizontal and vertical directions. Finally, a pair of pressing components drive the pressure block and pressure plate to press and cooperate with the positioning support block and the fixed support block to clamp and fix the seat side plate, thereby pressing and clamping the seat Buckle bracket and the seat cup holder fixing bracket, completing the positioning and clamping operation of the seat side plate assembly. This facilitates the positioning and clamping of the seat side plate assembly, prevents loosening at the connection, and enhances the anti-loosening effect.

[0016] By connecting the inner hole of the second spot-welded nut to the connecting pin, the second spot-welded nut is placed at a suitable position on the seat plate, completing the positioning connection between the second spot-welded nut and the seat plate. At the same time, the pressing component moves the pressure plate downward and cooperates with the fixed support block to press and clamp the seat plate, while simultaneously driving the pressure column and the spot-welded nut support block to press and clamp the second spot-welded nut. This facilitates the positioning and clamping of the second spot-welded nut and the seat plate, and then the welding operation is performed at the connection. There is no need to use additional tooling for additional positioning and clamping between the second spot-welded nut and the seat plate, thus saving the cost of additional tooling and welding costs.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a technical solution: a positioning and clamping fixture for welding seat side plate assemblies, comprising:

[0026] The base plate 1 has a positioning support block 5 on one side of its top and a fixing support block 11 on the other side of its top. The positioning support block 5 and the fixing support block 11 are respectively provided with positioning pins 51 and stop pins 111 that match the through holes 1331 on the seat side plate 133 in the seat side plate assembly 13. A pressure block 4 is provided above the positioning pin 51 and a pressure plate 10 is provided above the stop pin 111. A pair of pressing components 2 are provided on the top of the base plate 1 to drive the pressure block 4 and the pressure plate 10 to press and cooperate with the positioning support block 5 and the fixing support block 11 respectively to clamp and fix the seat side plate 133 in the seat side plate assembly 13.

[0027] The top of the base plate 1 is provided with a first limiting plate 7 and a second limiting plate 12 respectively. The top of the first limiting plate 7 is provided with a first limiting groove 71, and the top of the second limiting plate 12 is provided with a second limiting groove 122. The first limiting groove 71 and the second limiting groove 122 form a placement groove 14 that matches the seat buckle bracket 131 in the seat side panel assembly 13. The top of the second limiting plate 12 is provided with a limiting pin 121 that matches the first spot weld nut 1311 on the seat buckle bracket 131 in the seat side panel assembly 13.

[0028] The top of the base plate 1 is provided with a pair of positioning seats 6 for supporting the seat cup holder fixing bracket 132 in the seat side panel assembly 13. Each pair of positioning seats 6 has a positioning pin 61 on its top that matches the positioning hole 1321 on the seat cup holder fixing bracket 132 in the seat side panel assembly 13. This design positions the seat cup holder fixing bracket 132 by connecting it to the positioning pin 61 on the pair of positioning seats 6 through its positioning hole 1321. The positioning seats 6 support the bottom of the seat cup holder fixing bracket 132, and the positioning pin 61 and positioning hole 1321 prevent the seat cup holder fixing bracket 132 from moving in the lateral and longitudinal directions. Then, the seat buckle bracket 131 is placed inside the placement groove 14, with its two sides respectively abutting against the inner walls of the first limiting groove 71 and the second limiting groove 122. Simultaneously, the inner hole of the first spot-welded nut 1311 on the seat buckle bracket 131 is connected to the limiting pin 121, preventing the seat buckle bracket 131 from moving in the lateral and longitudinal directions. Then, the through holes 1331 on the seat side plate 133 are connected to the positioning pins 51 on the positioning support block 5 and the stop pins 111 on the fixed support block 11, respectively, to prevent the seat side plate 133 from moving in the lateral and longitudinal directions. At this time, the seat side plate 133 is fitted and clamped with the seat buckle bracket 131 and the seat cup holder fixing bracket 132 to complete the assembly and positioning of the seat side plate assembly 13. Finally, the pair of pressing components 2 drive the pressing block 4 and the pressing plate 10 to respectively connect with the positioning support block 5 and the fixed support block 11. The blocks 11 are pressed together to clamp and fix the seat side plate 133, and then the seat buckle bracket 131 and the seat cup holder fixing bracket 132 are pressed and clamped to complete the positioning and clamping operation of the seat side plate assembly 13. This facilitates the positioning and clamping of the seat side plate assembly 13, prevents the connection from loosening, and enhances the anti-loosening effect. Then, the connection between the seat buckle bracket 131, the seat cup holder fixing bracket 132 and the seat side plate 133 is welded.

[0029] Reference Figure 1 and Figure 2 The pressing component 2 includes a support base 21 disposed on the top of the base plate 1, and a vertical clamp 22 disposed on the top of the support base 21;

[0030] The vertical clamps 22 in the pair of pressing components 2 are connected to the pressing block 4 and the pressing plate 10 respectively. This design facilitates the pressing block 4 and the pressing plate 10 to press and cooperate with the positioning support block 5 and the fixed support block 11 respectively to clamp and fix the seat side plate 133.

[0031] Reference Figure 2 and Figure 3 The base plate 1 has an extension support block 3 located below the pressure block 4 and used to support the seat side plate 133 in the seat side plate assembly 13. This design uses the extension support block 3 to press and engage with the pressure block 4 to further press and clamp the seat side plate 133, thereby improving the clamping stability and welding stability. Extension blocks 101 are provided on both opposite side walls of the pressure plate 10. At the bottom of the extension blocks 101 is a pressure post 9 for pressing the second spot weld nut 1332 on the seat side plate 133 in the seat side plate assembly 13. At the top of the base plate 1, corresponding to the pressure post 9, is a spot weld nut support block 8 for supporting the second spot weld nut 1332 on the seat side plate 133 in the seat side plate assembly 13. The top of the spot weld nut support block 8 has a connecting pin that matches the inner hole of the second spot weld nut 1332. 81. This design connects the inner hole of the spot welding nut with the connecting pin 81, and places the second spot welding nut 1332 at a suitable position on the seat plate 133, thus completing the positioning connection between the second spot welding nut 1332 and the seat plate 133. When the pressing component 2 drives the pressure plate 10 to move downward and cooperates with the fixed support block 11 to press and clamp the seat plate 133, it also drives the pressure column 9 to press and cooperate with the spot welding nut support block 8 to press and tighten the second spot welding nut 1332. This facilitates the positioning and clamping of the second spot welding nut 1332 and the seat plate 133, and then the welding operation is performed at the connection. It is not necessary to use additional tooling to perform additional positioning and clamping between the second spot welding nut 1332 and the seat plate 133, thus saving the cost of additional tooling and thus saving welding costs. During positioning and clamping, the connecting pin 81 does not protrude from the upper end face of the second spot welding nut 1332.

[0032] Reference Figure 3 The pressure column 9 includes a connecting column 91 that runs through the inside of the extension block 101. A pressure plate 92 is provided at the bottom of the connecting column 91. This design improves the stability of the positioning and clamping of the second spot welded nut 1332.

[0033] Reference Figure 1 and Figure 5The bottom of the pressure block 4 is provided with a through groove 41 for avoiding the positioning pin 51, and the bottom of the pressure plate 10 is provided with a relief groove 102 for avoiding the stop pin 111. This design, by using the through groove 41 and the relief groove 102, facilitates the avoidance of the positioning pin 51 and the stop pin 111. Thus, when the pressure block 4 and the pressure plate 10 are pressed and engaged with the positioning support block 5 and the fixed support block 11 respectively to clamp and fix the seat plate 133, it ensures that the lower end face of the pressure block 4 and the pressure plate 10 is in contact with the upper end face of the seat plate 133, and the upper end face of the positioning support block 5 and the fixed support block 11 is in contact with the lower end face of the seat plate 133.

[0034] Reference Figures 1-5 As an embodiment of this utility model: when it is necessary to position and clamp the seat side panel assembly 13, the operator positions the seat cup holder fixing bracket 132 by connecting it to the positioning pins 61 on a pair of positioning seats 6 through the positioning holes 1321 on it. Under the action of the positioning seats 6, the bottom of the seat cup holder fixing bracket 132 is supported. Under the action of the positioning pins 61 and the positioning holes 1321, the seat cup holder fixing bracket 132 is prevented from moving in the lateral and longitudinal directions. Then, the seat buckle bracket 131 is placed in the placement... The inside of groove 14 and its two sides are respectively fitted with the inner walls of the first limiting groove 71 and the second limiting groove 122, and at the same time, the inner hole of the first spot-welded nut 1311 on the seat buckle bracket 131 is connected to the limiting pin 121 to prevent the seat buckle bracket 131 from moving in the lateral and longitudinal directions. Then, the through hole 1331 on the seat side plate 133 is connected to the positioning pin 51 on the positioning support block 5 and the stop pin 111 on the fixed support block 11 to prevent the seat side plate 133 from moving in the lateral and longitudinal directions. At this time, the seat side... Plate 133 is fitted and clamped to the seat buckle bracket 131 and seat cup holder fixing bracket 132 respectively to complete the assembly and positioning of the seat side plate assembly 13. Next, the inner hole of the second spot weld nut 1332 is connected to the connecting pin 81, and the second spot weld nut 1332 is placed in a suitable position on the seat side plate 133 to complete the positioning connection between the second spot weld nut 1332 and the seat side plate 133. Finally, the vertical clamps 22 in the pair of pressing components 2 drive the pressure block 4 and the pressure plate 10 to move downwards and respectively to the positioning support. The seat side plate 133 is clamped and fixed by pressing and engaging the block 5 and the fixed support block 11, thereby pressing and clamping the seat buckle bracket 131 and the seat cup holder fixing bracket 132, completing the positioning and clamping operation of the seat side plate assembly 13. This facilitates the positioning and clamping of the seat side plate assembly 13, prevents loosening at the connection, and enhances the anti-loosening effect. Then, the connection between the seat buckle bracket 131, the seat cup holder fixing bracket 132 and the seat side plate 133 is welded.

[0035] In the pressing assembly 2, the vertical clamp 22 drives the pressure plate 10 to move downward and cooperate with the fixed support block 11 to press and clamp the seat plate 133. At the same time, it drives the pressure column 9 to press and cooperate with the spot welding nut support block 8 to press and tighten the second spot welding nut 1332. This facilitates the positioning and clamping of the second spot welding nut 1332 and the seat plate 133. Then, the welding operation is performed at the connection. It is not necessary to use additional tooling to perform additional positioning and clamping between the second spot welding nut 1332 and the seat plate 133, thereby saving the cost of additional tooling and thus saving welding costs, improving the practicality of this utility model.
