Description

Technical Field

[0001] This utility model belongs to the field of automotive processing equipment technology, specifically a cutting tool for airbag covers. Background Technology

[0002] In the automotive industry, after automotive interior products are formed, there will be a gate for the glue. The shearing method will vary depending on the gate type. Laser cutting is one such shearing method, which can cut thicker gates, resulting in a flat and smooth surface.

[0003] Existing cutting methods all have certain shortcomings:

[0004] Mechanical shearing: requires a large shearing space; too narrow an inlet cannot be cut, and a thicker inlet cannot guarantee the cutting effect; and repeated adjustments are required in actual use.

[0005] Laser cutting equipment: requires a lot of space for equipment placement, and most require the addition of robotic arms for linkage cutting, which is costly;

[0006] Manual trimming: It cannot guarantee the consistency of the trimmed parts, there will be residue, and personnel are prone to danger during the operation.

[0007] In summary, the problems are: poor repeatability and residual components; long adjustment time and difficulty in adjustment; large space requirement and high cost; and impact on production cycle. Utility Model Content

[0008] The technical solution of this utility model is as follows: a safety airbag cover cutting tool includes a base, a connecting plate, a rotary cylinder, a contour clamp, a handle, a bearing, and a positioning block. One end of the connecting plate is rotatably connected to the base through the bearing, and the other end of the connecting plate is set on the output shaft of the rotary cylinder. The rotation of the output shaft of the rotary cylinder can drive the connecting plate to rotate. The connecting plate is provided with a positioning block and a contour clamp, and the contour clamp is provided with a handle.

[0009] Furthermore, it also includes a protective plate, which is set on the positioning block.

[0010] Furthermore, it also includes a limit block, which is set on the base.

[0011] The beneficial effects of this utility model are as follows:

[0012] Without increasing costs, this invention uses mechanical structures and pneumatic components to maintain the product's glue inlet position perpendicular to the laser generator. Using this device reduces glue residue at the inlet, minimizes space occupation, reduces adjustment time, shortens production cycles, and lowers overall costs. Attached Figure Description

[0019] It should be noted that in the description of this utility model, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," and "joining" should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; a connection can be a mechanical connection or an electrical connection; a joint can be a direct connection or an indirect connection through an intermediate medium, and can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] An airbag cover cutting fixture includes a base 1, a connecting plate 2, a rotary cylinder 3, a contour clamp 4, a protective plate 6, a limit block 7, a bearing 8, a positioning block 9, and a handle 11. The base 1 is connected to the connecting plate 2 through the bearing 8. The connecting plate 2 is mounted on the output shaft of the rotary cylinder 3, and the rotary cylinder 3 can drive the connecting plate 2 to rotate.

[0022] The connecting plate 2 is provided with a positioning block 9 and a contour clamp 4. The contour clamp 4 and the positioning block 9 work together to fix the product 12. The protective plate 6 is set on the positioning block 9. The protective plate 6 is used to prevent laser cutting from reaching the surface of the product 12.

[0023] The base 1 is equipped with a limit block 7 to limit the flipping angle of the connecting plate 2.

[0024] The contour clamp 4 is equipped with a handle 11, which can control the opening and closing of the contour clamp 4.

[0025] The laser emitter 10 is positioned in a specific location to ensure that the position of the product 12's glue inlet is always perpendicular to the laser generator 10.

[0026] The contour clamp 4 is used to fix the product 12 to prevent scratches, the positioning block 9 is used to improve the repeatability accuracy of the product 12, the connecting plate 2 is used to connect all mechanical structures, the rotary cylinder 3 can rotate the product 12, the bearing 8 can make the rotation process smoother, the protective plate 6 prevents laser cutting to the surface of the product 12, and the limit block 7 fixes the rotation angle. Rotation and alignment are completed through a simple mechanical structure, reducing development costs.

[0027] Finally, the material rod 5 is cut off.

[0028] The advantages of this utility model are:

[0029] The shearing method is adjusted according to the actual product conditions, and the shearing angle is adjusted by rotating cylinder instead of using a robotic arm;

[0030] The material is relatively soft after the product is formed. The positioning and contouring dimensions are slightly larger than the data dimensions to increase positioning accuracy.

[0031] The protective material for laser cutting is made of copper, which has a laser refraction angle greater than 90° to prevent damage to the laser emitter. Copper also has good heat dissipation properties.

[0032] The contour clamp 4, after the product 12 is placed in the tooling, is locked by the contour clamp 4 and the positioning block 9 to prevent the operation of the equipment from affecting the cutting accuracy.

[0033] Positioning block 9 is made of nylon and its shape completely mimics the product's form. The outer contour of positioning block 9 is 0.05mm smaller than the actual product size, ensuring placement accuracy while meeting positioning requirements.

[0034] Connecting plate 2 fixes positioning block 9, contour clamp 4, and protective plate 6 to the tooling base plate to form a unified whole.

[0035] The rotary cylinder 3 is used when there are material rods 5 on both sides of the product, and the cutting surfaces of the material rods 5 on both sides are not parallel. It is necessary to rotate to adjust the direction of the cutting surfaces to avoid rework.

[0036] The rotation of the bearing 8 fixture is driven by the rotary cylinder 3. One end of the fixture is the rotary cylinder 3, and the other end is the ordinary optical shaft, i.e., the base 1. Repeated operation of the fixture will produce tiny scratches on the surface of the optical shaft, i.e., the base 1. After multiple runs, the scratches will cause the fixture to rotate inefficiently, deviate from the rotation angle, and become stuck. The function of the bearing 8 is to reduce the wear caused by rotation and improve the rotation accuracy and efficiency.

[0037] The protective plate 6 is used for laser cutting of the cutting rod 5. The cutting curve of the cutting rod 5 coincides with the surface of the product 12. This results in a laser cutting line appearing on the product surface after the rod is removed. The protective plate 6 is positioned at the bottom of the laser path to prevent damage to the product 12 during cutting. The protective plate 6 is made of copper, which has good heat dissipation, preventing the laser from damaging it at a certain height.

[0038] The limit block 7 is a tool that uses a cylinder to adjust the cutting angle. The cylinder has a tolerance in its operation. The function of the limit block 7 is to ensure that when the cutting angle reaches the specified position, the rotating cylinder 3 continuously applies pressure and remains stationary after contacting the limit block 7, thus compensating for the operating tolerance of the rotating cylinder 3 and improving the cutting accuracy.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in this utility model, and within the spirit and principles of this utility model, should be included within the protection scope of this utility model.
