Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to an automotive grille cutting and positioning fixture. Background Technology

[0002] Car grilles are typically located at the front of a vehicle and serve both cooling and decorative purposes. They are mostly made of metal, plastic, or composite materials. Depending on the material and manufacturing process, metal grilles may be formed using stamping or casting, while plastic grilles are often injection molded. Composite material grilles involve more complex processing and cutting steps. Furthermore, due to the differences between traditional gasoline-powered vehicles and new energy vehicles, the processing of grilles requires the use of more complex laser cutting techniques.

[0003] In the grille cutting process, laser cutting is used for grilles with complex designs, while waterjet cutting is used for grilles made of special materials. During the cutting operation, a suction cup is mostly used to position the grille, ensuring it is stably subjected to the cutting operation. However, while the suction cup is positioning the grille, subsequent grille conveying operations cannot be performed, affecting the efficiency of continuous grille cutting. Therefore, this application provides a positioning fixture for automotive grille cutting. Utility Model Content

[0004] To address the aforementioned issues, this application provides a tooling for cutting and positioning automotive grilles.

[0005] To achieve the above objectives, this application provides the following technical solution: a car grille cutting and positioning fixture, including a table and a receiving platform disposed above the table. Both the table and the receiving platform are hollow structures. Two sets of first positioning seats and second positioning seats are symmetrically arranged on the receiving platform. When the car grille is placed on the surface of the first positioning seats and the second positioning seats, the cutting robot is located below the table to perform the cutting operation.

[0006] The first positioning seat and the second positioning seat are respectively provided with a rotatable first limiting pressure rod and a second limiting pressure rod. The gap space between the first positioning seat and the second positioning seat on the same side is provided with a docking support rod that can rotate synchronously with the first limiting pressure rod and the second limiting pressure rod. When the first limiting pressure rod and the second limiting pressure rod rotate and abut against the outside of the car grille, the docking support rod rotates and abuts against the inside of the car grille.

[0007] Furthermore, the first limiting rod and the second limiting rod, located on the same side of the receiving platform, are connected by a connecting rod. A rotatable first rotating rod is fixed on the connecting rod. The first rotating rod is distributed in a U-shape, and a linkage gear is provided at the end of the first rotating rod away from the connecting rod. When the linkage gear rotates, the first rotating rod, the connecting rod, the first limiting rod, and the second limiting rod rotate synchronously until the first limiting rod and the second limiting rod abut against the outer arc surface of the car grille.

[0008] Furthermore, each of the linkage gears has a drive gear at its bottom end that meshes with it. Each drive gear has a positioning shaft that can rotate synchronously with it. Two positioning shafts located on the same side of the receiving platform are connected by the same second rotating rod. The second rotating rod has a U-shaped structure, and the docking support rod is located at its center. When the drive gear rotates, the second rotating rod rotates within the relative space of the first positioning seat and the second positioning seat until the docking support rod abuts against the inner arc surface of the car grille.

[0009] Furthermore, one of the two positioning shafts located on the same side of the receiving platform is connected to a drive motor, and the drive motor is fixedly installed to the platform via a positioning bracket.

[0010] Furthermore, the first rotating rod and the positioning shaft, located on the same side of the receiving platform, are both mounted on the same partition plate via bearings. The upper and lower ends of the partition plate are provided with channels for the first rotating rod and the second rotating rod to rotate.

[0011] Furthermore, both ends of the receiving platform are provided with accommodating notches that can accommodate the rotation of the second rotating rod and the docking support rod. The accommodating notches are located between the first positioning seat and the second positioning seat.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This invention allows for simultaneous positioning on both the inner and outer sides of a car grille, abutting against the arc-shaped surfaces of the inner and outer sides of the grille. This provides simultaneous positioning on both the inner and outer sides, improving positioning speed. This positioning method effectively prevents the car grille from shifting during cutting operations, further enhancing its stability during these processes. Attached Figure Description

[0021] 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.

[0022] Example: Reference Figure 1-4 The car grille cutting and positioning fixture shown includes a table 1 and a receiving platform 2 located above the table 1. Both the table 1 and the receiving platform 2 are hollow structures. The receiving platform 2 is provided with two sets of first positioning seats 3 and second positioning seats 4 arranged symmetrically. When the car grille is placed on the surface of the first positioning seats 3 and the second positioning seats 4, the cutting robot is located below the table 1 to perform the cutting operation.

[0023] Both the first positioning seat 3 and the second positioning seat 4 are equipped with a rotatable first limiting pressure rod 5 and a second limiting pressure rod 6. Within the gap space between the first positioning seat 3 and the second positioning seat 4 on the same side, there is a docking support rod 7 that can rotate synchronously with the first limiting pressure rod 5 and the second limiting pressure rod 6. When the first limiting pressure rod 5 and the second limiting pressure rod 6 rotate and abut against the outer side of the car grille, the docking support rod 7 rotates and abuts against the inner side of the car grille. The first limiting pressure rod 5, the second limiting pressure rod 6, and the docking support rod 7 can perform synchronous positioning operations on the inner and outer sides of the car grille, pressing against the arc-shaped surfaces of the inner and outer sides of the car grille, maintaining the stability of the car grille during cutting operations, reducing cutting deviation, and effectively ensuring cutting accuracy.

[0024] The first limiting rod 5 and the second limiting rod 6, located on the same side of the receiving platform 2, are connected by a connecting rod 8. A rotatable first rotating rod 9 is fixed on the connecting rod 8. The first rotating rod 9 is distributed in a U-shape, and a linkage gear 10 is provided at the end of the first rotating rod 9 away from the connecting rod 8. When the linkage gear 10 rotates, the first rotating rod 9, the connecting rod 8, the first limiting rod 5, and the second limiting rod 6 rotate synchronously until the first limiting rod 5 and the second limiting rod 6 abut against the outer arc surface of the car grille.

[0025] Furthermore, in order to ensure that the first limiting pressure rod 5 and the second limiting pressure rod 6 can smoothly abut against the outer arc surface of the car grille, the bottom end of the linkage gear 10 is provided with a driving gear 11 that meshes with it. The driving gear 11 is provided with a positioning shaft 12 that can rotate synchronously with it. The two positioning shafts 12 located on the same side of the receiving platform 2 are connected by the same second rotating rod 13. The second rotating rod 13 has a U-shaped structure, and the docking support rod 7 is located at its center.

[0026] When the drive gear 11 rotates, the second rotating rod 13 rotates within the relative space between the first positioning seat 3 and the second positioning seat 4 until the docking support rod 7 abuts against the inner arc-shaped surface of the car grille. At the same time, under the meshing force of the drive gear 11 and the linkage gear 10, the first rotating rod 9 and the connecting rod 8 can rotate synchronously, thereby causing the first limiting pressure rod 5 and the second limiting pressure rod 6 to rotate until they abut against the outer arc-shaped surface of the car grille.

[0027] Therefore, when the connecting rod 7 abuts against the inner arc-shaped surface of the car grille, the first limiting rod 5 and the second limiting rod 6 abut against the outer arc-shaped surface of the car grille, achieving synchronous positioning of the inner and outer sides and improving the positioning speed. This positioning method effectively prevents the car grille from shifting during the cutting process, further enhancing its stability during cutting.

[0028] like Figure 4As shown, one of the two positioning shafts 12 located on the same side of the receiving platform 2 is connected to a drive motor 14. The drive motor 14 is fixedly installed on the platform 1 via a positioning bracket 15. The drive motor 14 provides power for the rotation of the positioning shaft 12 and the drive gear 11, thereby causing the drive gear 11 to mesh with the linkage gear 10 and rotate. This enables the first limiting pressure rod 5, the second limiting pressure rod 6, and the docking support rod 7 to perform synchronous positioning operations on the inner and outer sides of the car grille.

[0029] like Figure 4 As shown, to maintain the stability of the first rotating rod 9 and the positioning shaft 12 during rotation, the first rotating rod 9 and the positioning shaft 12, located on the same side of the receiving platform 2, are both mounted on the same partition 16 via bearings. The partition 16 provides support for the first rotating rod 9, the positioning shaft 12, and the linkage gear 10 and the drive gear 11 mounted thereon. The upper and lower ends of the partition 16 are provided with channels 17 for the first rotating rod 9 and the second rotating rod 13 to rotate. The channels 17 allow the first rotating rod 9 and the second rotating rod 13 to pass smoothly through the inner and outer sides of the partition 16.

[0030] like Figure 3 As shown, both ends of the receiving platform 2 are provided with accommodating notches 18 that can accommodate the rotation of the second rotating rod 13 and the docking support rod 7. The accommodating notches 18 are located between the first positioning seat 3 and the second positioning seat 4. The accommodating notches 18 provide space for the second rotating rod 13 and the docking support rod 7 to move smoothly to the top and bottom of the receiving platform 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
