[0002] Automotive sheet metal parts are an important component of the car body, and their processing quality directly affects the car's appearance, safety, and performance. With the development of the automotive industry, higher requirements have been placed on the processing accuracy and efficiency of complex curved sheet metal parts. Punching is one of the key processes in sheet metal processing, used to cut sheet metal materials into the required shapes and sizes. The clamping mechanism of existing automotive sheet metal punching positioning devices is usually a downward vertical pressing method, without a horizontal clamping effect, resulting in low positioning accuracy, inability to accurately align the punching blade, poor fixing effect, and thus affecting the punching quality. To address this, we propose an automotive sheet metal punching positioning device. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-6 As shown, this utility model is a punching and positioning device for automotive sheet metal parts, including a worktable 1 and an electric cylinder 2. The electric cylinder 2 is mounted on a mounting plate 3. A guide post 4 is fixedly connected to the mounting plate 3. There are four guide posts 4. One end of each of the four guide posts 4 passes through a pressure plate 5 and is fixedly connected to the worktable 1. A self-centering clamping mechanism 6 is provided on the worktable 1.

[0026] The self-centering clamping mechanism 6 includes a device slot 61, which is located on the workbench 1. Two drive plates 62 are slidably connected within the device slot 61, and a cylinder 63 is installed between the two drive plates 62. A support plate 64 is fixedly connected within the device slot 61, and two drive slots 65 are provided on the support plate 64. The tops of the two drive plates 62 pass through the corresponding drive slots 65 and are fixedly connected to a connecting plate 66. Two sliders 67 are symmetrically arranged at the bottom of the connecting plate 66, and two slide rails 68 are slidably connected to each slider 67. The slide rails 68 are fixedly connected to the support plate 64. A linkage assembly 7 is provided on the support plate 64, and a bidirectional clamping assembly 8 is provided on the connecting plate 66.

[0027] The top height of the connecting plate 66 should be lower than the bottom height of the placement plate 9 to increase the adjustment range of the self-centering clamping mechanism 6.

[0028] The linkage component 7 includes a drive link 71 and a synchronization plate 72. There are two drive links 71, and a first rotating shaft 73 and a second rotating shaft 74 are rotatably connected to each of the two drive links 71. The two first rotating shafts 73 are fixedly connected to the corresponding connecting plate 66, and the two second rotating shafts 74 are fixedly connected to the synchronization plate 72. A central shaft 75 is rotatably connected to the synchronization plate 72, and the central shaft 75 is fixedly connected to the connecting plate 66.

[0029] The cylinder 63 pushes the drive plates 62 on both sides, and in conjunction with the linkage component 7, the sliders 67 on both sides slide simultaneously and drive the connecting plate 66 to move towards the center of the placement plate 9. This ensures the synchronization of the movement on both sides, and can accurately position the workpiece to be processed at the center of the placement plate, thus improving the quality of punching.

[0030] The bidirectional clamping assembly 8 includes a U-shaped plate 81 and an L-shaped plate 82. The U-shaped plate 81 is fixedly connected to the connecting plate 66. A clamping plate assembly 83 is fixedly connected to one side of the U-shaped plate 81. There are two clamping plate assemblies 83 and two L-shaped plates 82. A plate shaft 84 is fixedly connected to the two L-shaped plates 82. There are two plate shafts 84. The two plate shafts 84 are rotatably connected to the inner side of the corresponding clamping plate assembly 83. A wheel groove 85 is opened on the L-shaped plate 82. There are two wheel grooves 85. A wheel shaft 86 is fixedly connected to each of the two wheel grooves 85. A roller 87 is rotatably connected to the wheel shaft 86.

[0031] To broaden the adaptability of the device, the U-shaped plate 81 can be designed as a height-adjustable plate, or the fixing position of the clamping plate assembly 83 on the U-shaped plate 81 can be designed as adjustable. Through the rotatable L-shaped plate 82, the device can be adapted to various shapes and irregular surfaces of sheet metal parts when fixing workpieces, increasing the adaptability of the device and reducing production costs. At the same time, the rollers 87 in both vertical and horizontal directions of the L-shaped plate 82 clamp the workpiece in both vertical and horizontal directions, resulting in better fixing effect and a certain positioning effect, which is beneficial to improving the punching quality of the product.

[0032] The drive board 62 is slidably connected to the corresponding drive slot 65.

[0033] The L-shaped plate 82 is rotatably connected to the clamping plate assembly 83, and the roller 87 is rotatably connected to the wheel groove 85.

[0034] A placement plate 9 is fixedly connected to the workbench 1. An adjustable positioning plate 10 is provided on the placement plate 9. There are two adjustable positioning plates 10. The movable end of the electric cylinder 2 passes through the mounting plate 3 and is fixedly connected to the punching and cutting blade assembly 11. The pressure plate 5 and the guide post 4 are slidably connected.

[0035] By adjusting the bidirectional clamping components 8 on both sides through the slide rail 68 and the slider 67, and in conjunction with the adjustable positioning plate 10, the positioning accuracy is improved, while the device is adapted to workpieces of different sizes, making it widely applicable and reducing the cost of automobile production and processing.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] The working principle of this utility model is as follows: When clamping the workpiece, the cylinder 63 shortens to reduce the distance between the two drive plates 62, thereby driving the two connecting plates 66 to move towards each other, and then driving the slider 67 to move along the slide rail 68 towards the center of the placement plate 9. At the same time, the drive linkage 71 connected to the bottom of the connecting plate 66 rotates around the first rotating shaft 73, thereby driving the second rotating shaft 74 and the synchronous plate 72 to rotate around the central shaft 75, ensuring that the movement on both sides is synchronized and does not deviate. The connecting plate 66 drives the U-shaped plate 81 to move closer to the workpiece. When the roller 87 contacts the surface of the workpiece, the roller 87 rolls on the surface of the workpiece to a suitable position and drives the L-shaped plate to rotate to a suitable angle, and then clamps the workpiece.
