Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically an adjustable seat cushion welding positioning device. Background Technology

[0002] The welding process for car seat cushions involves multiple steps, including positioning, fixing, welding, and post-processing. Specialized tooling and welding techniques are required to ensure structural stability and precision.

[0003] Regarding the welding process of the seat cushion frame, the frame components to be welded need to be positioned using tooling first, and then the components are welded together in pairs. During the welding process, the stability of the tooling clamping directly determines the quality of the weld.

[0004] In the existing technology, when positioning the skeleton components, it was found that the current positioning structure is fixed and cannot be flexibly adjusted to follow the changes in the welding points. It can only meet the needs of different welding positions through complex positioning adjustments. Therefore, we propose an adjustable seat cushion welding positioning device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an adjustable seat cushion welding positioning device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable seat cushion welding positioning device, including a tooling table, a base plate slidably disposed on the end face of the tooling table, a first clamping plate slidably connected to one side of the top of the base plate, a second clamping plate disposed on the other side of the top of the base plate, and an adjustment groove for assisting the adjustment of the second clamping plate is opened below the second clamping plate on the end face of the base plate. A limiting structure for clamping and limiting the second clamping plate is installed in the adjustment groove. The limiting structure includes limiting plates disposed on both sides of the second clamping plate, and the limiting plates are slidably connected to the inner wall of the adjustment groove. An extension portion extending to the outside of the base plate is connected to the end of the limiting plate, and a return spring is installed between the two sets of the extension portions.

[0007] By adopting the above technical solution, the seat cushion frame can be positioned, and the clamping method and position can be reasonably adjusted according to different welding points, which can better adapt to different welding and is simple to operate.

[0008] The present invention is further configured such that a sliding groove is provided on the end face of the tooling table, and an electric guide rail is installed in the sliding groove. A slider adapted to the electric guide rail is sleeved on the outer wall of the electric guide rail, and the slider is synchronously connected to the base plate.

[0009] By adopting the above technical solution, a driving effect is achieved on the base plate.

[0010] The present invention is further configured such that a vertical plate is fixed on one side of the top of the tooling table, and an electric push rod is installed on the inner end face of the vertical plate, and the output end of the electric push rod is laterally limited and longitudinally slidably connected to the outer wall of the first clamping plate.

[0011] By adopting the above technical solution, the first clamping plate is driven.

[0012] The present invention is further configured such that the top end of the slider is provided with a top plate fixedly connected to the bottom wall of the base plate, and the inside of the slider is provided with an adjusting rod extending to the outside of the slider. Two sets of lead screws are symmetrically installed inside the slider and are connected by a transmission turntable and a transmission belt. The outer walls of the two sets of lead screws are fitted with matching moving blocks, and the moving blocks are slidably limited to the inner wall of the slider through a sliding rod. The top end of the moving block is fixedly connected to a top rod fixedly connected to the bottom wall of the top plate.

[0013] By adopting the above technical solution, the base plate is lifted.

[0014] The present invention is further configured such that a first bevel gear is fixedly sleeved on the outer wall of the lead screw, and a second bevel gear fixed to the end of the adjusting rod is meshed with one side of the first bevel gear.

[0015] By adopting the above technical solution, the lead screw is driven.

[0016] In summary, the present invention has the following main advantages:

[0017] This utility model, by setting a first clamping plate and a second clamping plate, firstly, places the skeleton component to be welded between the two sets of clamping plates on the base plate. Then, the clamping position of the second clamping plate is adjusted according to the different welding positions. Specifically, by stretching the extension part to both sides, the extension part stretches the return spring and drives the limiting plate to move. At this time, the limiting plate releases the limitation on the second clamping plate. Then, the position of the second clamping plate can be adjusted to meet the welding requirements. After the adjustment is completed, the extension part can be released. At this time, the extension part will be reset under the action of the return spring, thereby driving the limiting plate to reset and achieving the limiting effect on the adjusted second clamping plate.

[0018] This invention, by setting an adjusting rod and a top plate, allows for adjustment of the clamping height of the seat cushion frame when welding at convenient positions such as the bottom of the frame. Specifically, rotating the adjusting rod drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear then drives the lead screw to rotate, which in turn drives the moving block on its outer wall to move. This movement of the moving block, in turn, drives the top plate upward via the top rod. Consequently, the top plate pushes the bottom plate upward, thus achieving adjustment of the clamping height of the seat cushion frame. Attached Figure Description

A second clamping plate 4 is disposed on the other side of the top of the base plate 2, and an adjustment groove 5 is provided below the second clamping plate 4 on the end face of the base plate 2 to assist in the adjustment of the second clamping plate 4. A limiting structure for clamping and limiting the second clamping plate 4 is installed in the adjustment groove 5.

[0028] Furthermore, in this embodiment, the limiting structure includes limiting plates 6 disposed on both sides of the second clamping plate 4, and the limiting plates 6 are slidably connected to the inner wall of the adjusting groove 5. The ends of the limiting plates 6 are connected to extension portions 7 extending to the outer side of the bottom plate 2, and a return spring 8 is installed between the two sets of extension portions 7.

[0029] Please see Figure 1The end face of the tooling table 1 is provided with a sliding groove 9, and an electric guide rail 10 is installed in the sliding groove 9. A slider 11 adapted to the electric guide rail 10 is sleeved on the outer wall of the electric guide rail 10, and the slider 11 is synchronously connected to the base plate 2 to realize the driving of the base plate 2.

[0030] Please see Figure 1 A vertical plate 12 is fixed on one side of the top of the tooling table 1, and an electric push rod 13 is installed on the inner end face of the vertical plate 12. The output end of the electric push rod 13 is connected to the outer wall of the first clamping plate 3 in a horizontal limiting connection and in a longitudinal sliding connection, thereby driving the first clamping plate 3.

[0031] Please see Figure 4-5 The top of the slider 11 is provided with a top plate 14 that is fixedly connected to the bottom wall of the base plate 2. The slider 11 is provided with an adjusting rod 15 that extends to the outside of the slider 11. Two sets of lead screws 16 are symmetrically installed inside the slider 11 and are connected by a transmission turntable and a transmission belt. The outer walls of the two sets of lead screws 16 are fitted with matching moving blocks 19. The moving blocks 19 are connected to the inner wall of the slider 11 by sliding rods. The top of the moving blocks 19 is fixedly connected with a top rod 20 that is fixedly connected to the bottom wall of the top plate 14.

[0032] The working principle of this utility model is as follows: First, the skeleton component to be welded is placed between two sets of clamping plates on the base plate 2. Then, the clamping position of the second clamping plate 4 is adjusted according to the different welding positions. Specifically, by stretching the extension part 7 to both sides, the extension part 7 stretches the return spring 8 and drives the limiting plate 6 to move. At this time, the limiting plate 6 releases the limitation on the second clamping plate 4. Then, the position of the second clamping plate 4 can be adjusted to meet the welding requirements. After the adjustment is completed, the extension part 7 can be released. At this time, the extension part 7 will be reset under the action of the return spring 8, thereby driving the limiting plate 6 to reset and achieve the limiting effect on the adjusted second clamping plate 4. At the same time, the electric push rod 13 is activated. The electric push rod 13 will drive the first clamping plate 3 to move, thereby cooperating with the second clamping plate 4 to complete the positioning work of the seat frame.

[0033] In addition, the slider 11 can be moved by activating the electric guide rail 10, and the movement of the slider 11 can drive the base plate 2 to move, thereby adapting to different specifications of seat cushion frames.

[0034] Furthermore, when welding the bottom of the seat cushion frame or other convenient welding positions, the clamping height of the seat cushion frame can be adjusted. Specifically, by rotating the adjusting rod 15, the adjusting rod 15 will drive the second bevel gear 18 to rotate. After the second bevel gear 18 rotates, it will drive the first bevel gear 17 to rotate. After the first bevel gear 17 rotates, it will drive the lead screw 16 to rotate. After the lead screw 16 rotates, it will drive the moving block 19 on its outer wall to move. The movement of the moving block 19 will drive the top plate 14 to move upward through the top rod 10. Therefore, the top plate 14 will push the bottom plate 2 to move upward, thereby realizing the adjustment of the clamping height of the seat cushion frame.
