[0002] Stamping, as one of the most widely used core processes in automotive parts manufacturing, covers almost all metal parts forming processes, including body panels (such as doors and hoods) and chassis structural parts (such as beams and brackets). Its principle is to apply high pressure to a metal sheet using a die, causing the sheet to be shaped according to the die cavity. Loading and positioning are indispensable key processes in automotive parts stamping production.

[0003] In the prior art, the stamping and positioning device for automotive parts can adopt a universal positioning fixture adjustment mode. This mode has no fixed and adaptable positioning structure. Each time a different specification of sheet is switched, the operator needs to install multiple independent positioning fixtures (such as positioning pins, edge blocks, and limit plates) one by one on the mold feeding platform according to the actual size and feature points (such as process holes and edge references) of the sheet. By adjusting the installation position and height of the positioning fixtures, a positioning reference adapted to the current sheet is formed. However, this universal positioning method requires the operator to complete a series of processes such as disassembling the positioning fixtures, measuring the position, and installing and debugging each time the sheet specification is changed. This is inefficient, and the installation position of the positioning fixtures is prone to errors due to the operator's installation experience, vibration, and other factors, which affects the production accuracy of automotive parts. Based on this, this application proposes a stamping and positioning device for automotive parts. Utility Model Content

[0022] 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.

[0023] This utility model provides an embodiment: Please refer to Figures 1-6 A stamping and positioning device for automotive parts includes a fixed part 1 and a replaceable part. The replaceable part is located on the top of the fixed part 1. The replaceable part includes a positioning tray 3 and a fixed outer frame 2 connected to the outer wall of the positioning tray 3. The positioning tray 3 is provided with a positioning groove adapted to the stamping sheet of the automotive parts. The replaceable part and the fixed part 1 are detachably connected by a connecting component. Through the modular design of the fixed part 1 and the replaceable part, this application can achieve flexible adaptation in practical applications: the operator only needs to select the matching replaceable part according to the stamping sheet of the automotive parts to be processed for quick replacement, so that this application can cover the stamping positioning needs of various automotive parts and improve the adjustment efficiency of the device. At the same time, the positioning groove of the precise equipment on the replaceable part matches the stamping sheet of the automotive parts, which can avoid the problem of mispositioning of the stamping sheet of the automotive parts due to the deviation of the positioning groove, thereby significantly improving the positioning reliability of the stamping sheet of the automotive parts and facilitating the subsequent processing of automotive parts.

[0024] The connecting assembly includes a fixing rod 7 connected to the bottom of the fixed outer frame 2, a push rod 8 movably connected to the inner cavity of the fixed part 1, and a horizontal insertion rod 11 movably connected to the inner cavity of the fixed part 1. A through groove 10 is provided at the top of the inner cavity of the fixed part 1. When the replaceable part is installed, the bottom end of the fixing rod 7 extends into the inner cavity of the fixed part 1 through the through groove 10. A horizontal slot 9 adapted to the horizontal insertion rod 11 is provided at the bottom end of the fixing rod 7. When the bottom of the replaceable part is tightly fitted with the top of the fixed part 1, the horizontal insertion rod 11 and the horizontal slot 9 are aligned. Under the action of external force, after the horizontal insertion rod 11 is inserted into the horizontal slot 9, the fixing rod 7 is fixed in position, thereby connecting the replaceable part and the fixed part 1. Under the action of external force, after the horizontal insertion rod 11 is separated from the horizontal slot 9, the connection between the replaceable part and the fixed part 1 can be released, making it easy to remove the replaceable part.

[0025] The push rod 8 is located directly below the through slot 10. The push rod 8 is connected to the top of the inner cavity of the fixing part 1 via a spring 14. The inner cavity of the fixing part 1 is provided with a guide rod 15. The push rod 8 is movably connected to the guide rod 15. The guide rod 15 can guide the push rod 8, allowing the push rod 8 to move in the vertical direction. Under the action of the spring 14's rebound force, the push rod 8 can move upward. When the horizontal insertion rod 11 separates from the horizontal slot 9, the upward movement of the push rod 8 can push the fixing rod 7 upward. The fixing rod 7 drives the replaceable part upward, causing the bottom of the replaceable part to separate from the top of the fixing part 1, providing a point of force for the operator. The operator can separate the replaceable part from the fixing part 1 by pulling upward, improving the convenience of operation and the speed of disassembly.

[0026] The push rod 8 is connected to the horizontal insertion rod 11 via a pull rope 12 and a guide wheel 13. The guide wheel 13 is movably connected to the inner cavity of the fixed part 1. The pull rope 12 is wound around the surface of the guide wheel 13. Under the action of the guide wheel 13, the end of the pull rope 12 connected to the horizontal insertion rod 11 is horizontal, and the end of the pull rope 12 connected to the bottom of the push rod 8 is vertical. With this configuration, when the horizontal insertion rod 11 approaches the fixed rod 7, the horizontal insertion rod 11 drives the push rod 8 downwards via the pull rope 12. When the horizontal insertion rod 11 moves away from the fixed rod 7, the push rod 8 can move upwards under the restoring force of the spring 14. Furthermore, when the top of the push rod 8 contacts the bottom of the fixed rod 7, the horizontal insertion rod 11 separates from the fixed rod 7.

[0027] A cylinder 5 is installed inside the cavity of the fixing part 1. The end of the output shaft of the cylinder 5 is connected to the end of the horizontal insert rod 11 away from the through groove 10. The operation of the cylinder 5 can drive the horizontal insert rod 11 to move, so that the controller of this application can realize quick disassembly and assembly of the replaceable part by controlling the extension and retraction of the cylinder 5, thereby improving the adjustment efficiency of the stamping material positioning fixture for automotive parts.

[0028] In Embodiment 1, fixing rods 7 are provided at the four corners of the bottom of the fixed outer frame 2. Horizontal insert rods 11, push rods 8, guide rods 15, springs 14, pull ropes 12, and guide wheels 13 are provided at corresponding positions inside the fixing part 1. Two horizontal insert rods 11 with the same direction of movement are connected by a connecting rod 6. The cylinder 5 is a double-headed cylinder, and the end of the output shaft of the cylinder 5 is connected to the connecting rod 6. Under the action of the double-headed cylinder, the multiple horizontal insert rods 11 in this application can move synchronously, thereby enabling the fixed outer frame 2 and the fixing part 1 to achieve multi-point synchronous connection or disassembly.

[0029] In addition, limit blocks 4 are evenly arranged on both sides of the top of the fixed part 1, and a limit groove 16 adapted to the limit block 4 is provided on the outer wall of the fixed outer frame 2 at the corresponding position. The height of the limit block 4 is not lower than the height of the fixed rod 7. When this application is running, the fixed outer frame 2 is precisely limited by the cooperation of the limit block 4 and the limit groove 16, ensuring that the fixed rod 7 is strictly aligned with the through groove 10, thereby significantly improving the assembly efficiency of the fixed rod 7 being inserted into the through groove 10; at the same time, the coordinated action of multiple limit blocks 4 can realize multi-directional positioning constraints on the replaceable part, effectively enhancing the positioning accuracy of the replaceable part. The height of the limit block 4 can be set according to the requirements and is not limited here. Furthermore, there is damping between the limit block 4 and the limit groove 16, so that when the external force is released, the relative position between the replaceable part and the limit block 4 can remain stable, which facilitates the cylinder 5 to drive the push rod 8 and the horizontal insertion rod 11 to reset.

[0030] In summary: When using this automotive parts stamping and positioning device, the positioning groove is used to position the stamped automotive parts. When switching between different specifications of parts, the operator controls the cylinder 5 to work. The cylinder 5 drives the horizontal insert rod 11 connected to it away from the fixed rod 7. After the horizontal insert rod 11 separates from the fixed rod 7, the replaceable part is disconnected from the fixed part 1. The continued movement of the horizontal insert rod 11 can cause the push rod 8 to drive the fixed rod 7 upward until the horizontal insert rod 11 moves to the preset position. At this time, the bottom of the fixed rod 7 is at the same height as the top of the fixed part 1. There is a gap between the bottom of the replaceable part and the fixed part 1. The replaceable part is lifted upward, which can realize the removal of the replaceable part. After the bottom of the fixed rod 7 is at the same height as the top of the fixed part 1, the cylinder 5 drives the horizontal insert rod 11 and the push rod 8 to reset.

[0031] The worker selects a replaceable part that matches the stamped sheet of the automotive part. After aligning the limiting groove 16 of the replaceable part to be installed with the limiting block 4, the worker presses the replaceable part down. The fixing rod 7 can be inserted into the inner cavity of the fixing part 1 through the through groove 10. After the bottom of the replaceable part is tightly fitted with the top of the fixing part 1, the worker controls the cylinder 5 to work. The cylinder 5 drives the horizontal insertion rod 11 connected to it to approach the fixing rod 7. Under the action of the cylinder 5, the horizontal insertion rod 11 can be inserted into the horizontal slot 9 to limit the fixing rod 7, thereby connecting the replaceable part with the fixing part 1 and enabling the replaceable part to be quickly replaced.
