Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting device manufacturing, in particular to a device for riveting a ventilation cap of a car lamp. Background Art

[0002] Car lights are always exposed to various climates, road conditions and environments that may affect the driving performance of the vehicle. Splashing water, humidity, car oil, road debris and dust will reduce the performance of the car lights. In addition, a rapid drop in temperature will also cause a drop in internal pressure, inhale pollutants, increase fogging or cause car light failure. Therefore, a breathable cap must be installed at the air vent of the car light. The breathable cap can effectively adjust the internal and external pressures as the environment changes, prevent rain, dust and pollutants from entering, and prevent the car lights from fogging and performance degradation. At present, the breathable cap is installed on the air vent of the car light by manual pressing. Since the breathable cap and the air vent need to fit closely, the hand strength needs to be large enough, which often causes pain in the workers' hands and is inefficient. In addition, manually pressing the breathable cap in cannot ensure that the breathable cap is completely pressed onto the air vent. The breathable cap may be tilted, which will cause the breathable cap to fail to protect the car lights.

[0003] Therefore, there is a need in the art for a device that can ensure the pressed-in position of the air vent cap and the air vent of the vehicle lamp, ensure assembly quality, save time and manpower, and improve production efficiency. Utility Model Content

[0005] To achieve the above purpose, the utility model provides the following solutions:

[0006] The utility model provides a device for riveting a ventilation cap of a vehicle lamp, comprising a riveting head, a fixing block hollow fastener, a vacuum generator and a ventilation cap, wherein an axial groove is provided at the center of the riveting head along the axial direction, a pyramid-shaped through hole is provided at the center of the fixing block along the axial direction, the hollow fastener can pass through the pyramid-shaped through hole to fix the fixing block and the riveting head, a transverse groove communicating with the axial groove is provided at the outer side of the riveting head, a horizontal plane where the transverse groove is located is higher than a horizontal plane where an upper end surface of the hollow fastener is located, a suction port of the vacuum generator can be inserted into the transverse groove, and when the vacuum generator is powered on to evacuate air, the upper surface of the ventilation cap can abut against the lower surface of the hollow fastener.

[0007] Preferably, the hollow fastener is a hollow bolt.

[0008] Preferably, the pyramid-shaped through holes include an upper through hole, a middle through hole and a lower through hole which are sequentially connected from top to bottom.

[0009] Preferably, the diameter of the upper through hole is the same as the diameter of the screw rod of the hollow bolt, the diameter of the middle through hole is greater than or equal to the diameter of the nut of the hollow bolt, and the diameter of the lower through hole is greater than the diameter of the breathable cap.

[0010] Preferably, the nut of the hollow bolt can abut against the upper surface of the middle through hole, and the screw rod of the hollow bolt can be inserted into the axial groove.

[0011] Preferably, a side wall groove is formed on the side wall of the riveting head, and the side wall groove is connected to the transverse groove.

[0012] Preferably, the transverse groove and the axial groove are perpendicular to each other.

[0013] Preferably, the air permeable cap matches the air permeable opening of the vehicle lamp housing.

[0014] Compared with the prior art, the utility model has achieved the following beneficial technical effects:

[0015] The utility model provides a device for riveting a ventilation cap of a headlight, comprising a riveting head, a fixing block, a hollow fastener, a vacuum generator and a ventilation cap. The hollow fastener passes through an axial groove to fix the riveting head and the fixing block.

[0022] The utility model provides a device for riveting a vent cap of a vehicle lamp, such as Figure 1 As shown, it includes a riveting head 1, a fixing block 2, a hollow fastener, a vacuum generator 4 and a breathable cap 5. An axial groove 6 is opened in the center of the riveting head 1 along the axial direction, and a pyramid-shaped through hole is opened in the center of the fixing block 2 along the axial direction. The hollow fastener can pass through the pyramid-shaped through hole to fix the fixing block 2 and the riveting head 1. A transverse groove 7 communicating with the axial groove 6 is opened on the outer side of the riveting head 1. The horizontal plane where the transverse groove 7 is located is higher than the horizontal plane where the upper end surface of the hollow fastener is located. The suction port 8 of the vacuum generator 4 can be inserted into the transverse groove 7. When the vacuum generator 4 is powered on to evacuate air, the upper surface of the breathable cap 5 can abut against the lower surface of the hollow fastener.

[0023] Specifically, the hollow fastener passes through the axial groove 6 to fix the riveting head 1 and the fixed block 2, and the suction port 8 of the vacuum generator 4 is inserted into the transverse groove 7. The transverse groove 7 is perpendicular to the axial groove 6 and communicates with the axial groove 6. When the vacuum generator 4 is powered on, the suction port 8 will suck the air in the axial groove 6. Since the hollow fastener is hollow, after the breathable cap 5 is placed under the fixed block 2, the breathable cap 2 will be pressed against the lower end face of the hollow fastener due to the suction force. At this time, the riveting press is started, and the riveting head 1 is moved above the breathable port of the lamp housing 13. The breathable cap 2 matches the breathable port 14 of the lamp housing 13, ensuring the pressed position of the breathable cap 5 and the breathable port 14 of the lamp housing 13, ensuring the assembly quality, realizing automatic riveting, saving time and manpower, and improving production efficiency.

[0024] In this embodiment, the hollow fastener is a hollow bolt 3, the diameter of the fixing block 2 is equal to the diameter of the riveting head 1, and the pyramid-shaped through hole includes an upper through hole 9, a middle through hole 10 and a lower through hole 11 which are sequentially connected from top to bottom. The diameter of the upper through hole 9 is the same as the diameter of the screw rod of the hollow bolt 3, the diameter of the middle through hole 10 is greater than or equal to the diameter of the nut of the hollow bolt 3, thereby ensuring a fixed connection between the riveting head 1 and the fixing block 2, and the diameter of the lower through hole 11 is greater than the diameter of the breathable cap 5, thereby ensuring that the breathable cap 5 can be adsorbed into the fixing block 2 due to the suction force.

[0025] In this embodiment, a side wall groove 12 is formed on the side wall of the riveting head 1, and the side wall groove 12 is connected to the transverse groove 7, so that the suction port 8 of the vacuum generator 4 is more firmly inserted into the transverse groove 7, thereby ensuring the application of the suction force.

[0026] In this embodiment, the nut of the hollow bolt 3 can abut against the upper surface of the middle through hole 10 , and the screw rod of the hollow bolt 3 can be inserted into the axial groove 6 , thereby achieving a fixed connection between the fixing block 2 and the riveting head 1 .
