With the continuous advancement of technology and the continuous expansion of application fields, the stable clamping platform will play a more important role in improving the welding quality and production efficiency of car seat frames.

[0003] However, the design of automobile seat frames usually needs to take into account the passenger's body shape, sitting posture and comfort. In order to meet these requirements, the seat frame usually has multiple bends and curvatures. The clamping method of the existing stable clamping platform is usually suitable for straight or simple-shaped workpieces. For automobile seat frames with complex curvatures, it is difficult to provide sufficient stability and uniformity, resulting in movement or deformation of the frame during welding.

[0004] In view of the above problems, the utility model provides a stable clamping platform for welding an automobile seat frame. Utility Model Content

[0007] The inner wall of the support seat is rotatably connected to a middle rod, and screw A and screw B are fixedly connected on both sides of the middle rod respectively. The outer wall of screw A is threadedly connected to the first slider, and the outer wall of screw B is threadedly connected to the second slider. A reinforcement block is fixedly connected to the outer wall of the opposite end of the first clamping block and the second clamping block.

[0014] Preferably, the reinforcement block is a component made of rubber material.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model proposes a stable clamping platform for welding a car seat frame, which utilizes a screw rod A to be externally connected to an electric motor, and drives the screw rod B to rotate simultaneously through a middle rod. Since the thread structures of the outer walls of the screw rods A and B are opposite, the first slider and the second slider are driven to approach each other, so that the connecting channel storage placement plate, the first clamping block and the second clamping block gradually clamp the car seat frame.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 In order to solve the problem that the clamping method of the existing stable clamping platform is usually suitable for straight or simple-shaped workpieces, it is difficult to provide sufficient stability and uniformity for the car seat frame with complex curvature, resulting in the movement or deformation of the frame during welding, the following preferred technical solutions are provided:

[0024] A stable clamping platform for welding an automobile seat frame comprises a workbench 1 and a support seat 2 fixed on the upper end of the workbench 1, a first slider 3 and a second slider 4 are slidably connected to the upper end of the workbench 1, a first clamping block 5 is fixedly connected to the upper end of the first slider 3, a second clamping block 6 is fixedly connected to the upper end of the second slider 4, a connecting channel 7 is provided inside the first slider 3 and the second slider 4, a placement plate 8 is provided between the first slider 3 and the second slider 4, a middle rod 9 is rotatably connected to the inner wall of the support seat 2, a screw A10 and a screw B11 are fixedly connected on both sides of the middle rod 9, an outer wall of the screw A10 is threadedly connected to the first slider 3, an outer wall of the screw B11 is threadedly connected to the second slider 4, a reinforcement block 12 is fixedly connected to the outer wall of the opposite end of the first clamping block 5 and the second clamping block 6, and the reinforcement block 12 is a component made of rubber material.

[0025] The placement plates 8 are slidably connected to the connecting channels 7 inside the first slider 3 and the second slider 4. The screws A10 and B11 are symmetrically distributed about the center of the middle rod 9. The thread structures of the outer walls of the screws A10 and B11 are opposite. There are multiple groups of reinforcement blocks 12, and they are evenly distributed about the outer walls of the first clamping block 5 and the second clamping block 6.

[0026] The inner wall of the reinforcement block 12 is axially connected with the first oblique rod 122 and the second oblique rod 123, and one end of the first oblique rod 122 and the second oblique rod 123 are respectively axially connected with the first pressure block 124 and the second pressure block 125, the first pressure block 124 and the second pressure block 125 are both slidably connected to the inner wall of the reinforcement block 12, and a return spring 126 is fixedly connected between the first pressure block 124 and the second pressure block 125.

[0027] Specifically, when clamping and fixing the car seat frame, first place it on the placement plate 8, use the screw A10 to connect an external motor, and drive the screw B11 to rotate simultaneously through the middle rod 9. Since the outer wall thread structures of the screw A10 and the screw B11 are opposite, the first slider 3 and the second slider 4 will be driven to move closer to each other, so that the connecting channel 7 accommodates the placement plate 8, and the first clamp block 5 and the second clamp block 6 gradually clamp the car seat frame. At this time, multiple groups of reinforcement blocks 12 will be compressed and deformed. Through their own recovery, multiple groups of reinforcement blocks 12 will reinforce the car seat frame, clamping and fixing the car seat frame with complex curvature, the effect is significant, and the clamping method of the existing stable clamping platform is solved. It is usually suitable for straight or simple-shaped workpieces. For car seat frames with complex curvatures, it is difficult to provide sufficient stability and uniformity, resulting in the movement or deformation of the frame during welding.

[0028] When the reinforcement block 12 is deformed under pressure, the first oblique rod 122 and the second oblique rod 123 will, under extrusion, drive the first pressure block 124 and the second pressure block 125 to move away from each other, and the return spring 126 will be stretched through the cooperation of the first pressure block 124 and the second pressure block 125. At this time, the reaction force of the return spring 126 will drive the first oblique rod 122 and the second oblique rod 123 to push the inner wall of the reinforcement block 12 through the first pressure block 124 and the second pressure block 125, thereby helping the reinforcement block 12 to recover quickly, thereby improving the reinforcement effect of the reinforcement block 12 on the car seat frame.

[0029] In summary: when clamping and fixing the car seat frame, first place it on the placement plate 8, use the screw A10 to connect the motor, and drive the screw B11 to rotate simultaneously through the middle rod 9. Since the outer wall thread structures of the screw A10 and the screw B11 are opposite, the first slider 3 and the second slider 4 will be driven to move closer to each other, so that the connecting channel 7 accommodates the placement plate 8, and the first clamping block 5 and the second clamping block 6 gradually clamp the car seat frame. At this time, the multiple groups of reinforcement blocks 12 will be compressed and deformed. Through their own recovery, the multiple groups of reinforcement blocks 12 will reinforce the car seat frame. , clamping and fixing the car seat frame with complex curvature, the effect is remarkable. When the reinforcement block 12 is compressed and deformed, the first oblique rod 122 and the second oblique rod 123 will drive the first pressing block 124 and the second pressing block 125 to move away from each other under the extrusion, and the reset spring 126 is stretched by the cooperation of the first pressing block 124 and the second pressing block 125. At this time, the reaction force of the reset spring 126 will drive the first oblique rod 122 and the second oblique rod 123 to push the inner wall of the reinforcement block 12 through the first pressing block 124 and the second pressing block 125, thereby helping the reinforcement block 12 to recover quickly.
