Description

Technical Field

[0001] This utility model relates to the technical field of automotive duct processing equipment, and in particular to a feeding mechanism for an automotive duct punching machine. Background Technology

[0002] Automotive air ducts are an important component of automotive air conditioning systems. During their production, multiple ventilation holes are machined into the duct wall using a punching machine. After punching, the finished duct is transferred from the punching station to the collection station via a feeding mechanism. In actual use, existing punching devices are prone to displacement of the air duct due to its own weight and conveying inertia caused by the conveyor belt, resulting in inaccurate punching position and rendering the air duct unusable. Therefore, a feeding mechanism for an automotive air duct punching machine is provided. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for an automotive duct punching machine. It uses an infrared sensor to detect the position of the duct, and the controller synchronously starts and stops the conveyor belt. The clamping assembly drives the clamping plate to fix the duct through a third electric push rod. The pressure sensor monitors in real time and maintains a constant clamping force to prevent the duct from shifting due to gravity and conveying inertia. This solves the problem of duct scrapping caused by inaccurate punching position and overcomes the shortcomings of existing technologies.

[0008] As a further improvement of this utility model: the hole-opening assembly includes a servo motor fixed in the middle of the lower end face of the lifting rod, and the output end of the servo motor is connected to a drill bit.

[0009] As a further embodiment of this utility model: the clamping assembly includes two third electric push rods fixed to the bottom ends of opposite sides of the vertical sections on both sides of the U-shaped rod.

[0022] The rotating bracket includes a support plate 10 that is rotatably mounted on the inner side of the U-shaped horizontal plate 5 and close to the end of the conveyor belt 3 via a rotating shaft. A first electric push rod 18 is rotatably connected between the lower end face of the support plate 10 and the side wall of the U-shaped vertical plate 2.

[0023] The lifting assembly includes a second electric push rod 13 fixed to the lower end of the middle section of the horizontal section of the U-shaped rod 8. The lower end of the second electric push rod 13 is connected to a lifting rod 7. Slide grooves 6 are provided on opposite sides of the vertical sections on both sides of the U-shaped rod 8.

The pressure sensor detects the pressure applied to the air duct by the clamping plates 12 and controls the extension and retraction of the two third electric push rods 11 according to the preset pressure value to maintain a constant clamping force on the air duct. Then, the controller 9 controls the servo motor 14 to drive the drill bit 15. Rotate, then control the second electric push rod 13 to push the lifting rod 7 down.

During the tilting of the support plate 10, the air duct after punching falls along the support plate 10 into the collection tray 4, and then the drilling of the next air duct can be carried out.
