Description

Technical Field

[0001] This utility model relates to the field of duct cutting technology, and in particular to an automotive duct cutting device with a rapid positioning mechanism. Background Technology

[0002] With the booming development of the automotive manufacturing industry, higher demands have been placed on the processing efficiency and precision of automotive ventilation system components. As an important part of the ventilation system, automotive ducts often need to be cut at both ends to ensure sealing and compatibility after installation. Traditional manual cutting methods are not only inefficient and labor-intensive, but also difficult to maintain consistent cutting quality, making it difficult to meet the needs of modern mass production. Currently, although some companies have adopted semi-automated cutting equipment, the fixing and positioning of ducts still suffers from cumbersome operations and long processing times, which has become a bottleneck restricting the improvement of overall production efficiency.

[0003] Existing duct cutting devices typically require manual placement and calibration of the duct before clamping using screws or cylinders. This process is time-consuming and the clamping force is difficult to control, which can easily lead to duct deformation or insecure fixation. Furthermore, the movement of the cutting mechanism relies heavily on manual advancement, resulting in poor positioning accuracy and severely affecting the quality and consistency of the cut. Therefore, this paper proposes an automotive duct cutting device with a rapid positioning mechanism. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 This utility model provides an automotive duct cutting device with a rapid positioning mechanism, including a worktable 1 and an upper clamp 12. The worktable 1 serves as the basic support platform for the entire device, providing an installation base for components such as the upper clamp 12 and the cutting mechanism. A slide groove 2 is provided on its upper side, which provides precise guidance for the movement of the slider 5 and restricts its movement trajectory. A first motor 3 is fixedly connected to one side of the worktable 1, which serves as a drive source to provide power. A lead screw 4 is fixedly connected to one side of the output shaft of the first motor 3. The lead screw 4 converts the rotational motion of the first motor 3 into linear motion, and the lead screw 4 is rotatably connected to the inner side of the slide groove 2. The lead screw 4 is threadedly connected to the outer side of the lead screw 4, and the slider 5 moves along the slide groove 2 under the drive of the lead screw 4, thereby driving the cutting mechanism to adjust its position. The slider 5 is slidably connected to the inner side of the slide groove 2.

[0018] like Figure 1 as well as Figure 2As shown, a cutting mechanism is installed on the upper side of the slider 5. The cutting mechanism is used to perform cutting operations on the automotive air duct. The cutting mechanism includes a mounting plate 6, a connecting plate 7, a second motor 8, a rotating rod 9, and a cutting blade 10. The mounting plate 6 serves as a connection and support, and is fixedly connected to the upper side of the slider 5. The connecting plate 7 is used to install and fix the second motor 8 and the rotating rod 9. It is fixedly connected to the upper side of the mounting plate 6, and there are two sets of connecting plates 7 arranged symmetrically to provide a stable support structure. The second motor 8 serves as the power source for the cutting blade 10 and is fixedly connected to the outside of one set of connecting plates 7. The rotating rod 9 is used to transmit the torque of the second motor 8 and to install the cutting blade 10. It is rotatably connected between the two sets of connecting plates 7, and the rotating rod 9 is fixedly connected to one side of the output shaft of the second motor 8. The cutting blade 10 is the terminal component for performing the cutting operation and is fixedly connected to the outside of the rotating rod 9.

[0019] like Figure 1 as well as Figure 4 As shown, a lower clamp 11 is fixedly connected to the upper side of the workbench 1. The lower clamp 11 and the upper clamp 12 work together to clamp and fix the air duct to be processed. The upper clamp 12 is installed directly above the lower clamp 11. A spring mechanism is installed between the upper clamp 12 and the lower clamp 11. The spring mechanism provides a restoring force to the upper clamp 12 and makes it quickly rise after being released. The spring mechanism includes a fixing block 13, a tension spring 14 and a telescopic rod 15. The fixing block 13 plays a connecting and fixing role. There are multiple sets of them and they are fixedly connected to both sides of the lower clamp 11 and the upper clamp 12. The tension spring 14 provides the main elastic restoring force. The telescopic rod 15 plays a guiding and stabilizing role and prevents the tension spring 14 from twisting. The tension spring 14 and the telescopic rod 15 are both fixedly connected between two sets of fixing blocks 13 located on the same side, and the tension spring 14 is sleeved on the outside of the telescopic rod 15.

[0020] like Figure 5 as well as Figure 6 As shown, the workbench 1 has a cavity 16 inside, which provides space for the installation of the positioning mechanism. The cavity 16 is located below the slide 2. The positioning mechanism is installed inside the cavity 16. The positioning mechanism is responsible for controlling the downward pressing action of the upper clamp 12 to achieve rapid clamping of the air duct. The positioning mechanism includes a rotating shaft 18 and a connecting rope 19. The rotating shaft 18 is used to wind and release the connecting rope 19. It is rotatably connected to the inside of the cavity 16. The connecting rope 19 is used to transmit tension and connect the rotating shaft 18 and the upper clamp 12. It is fixedly connected to the outside of the rotating shaft 18. The end of the connecting rope 19 passes through the upper side of the workbench 1 and the lower clamp 11 and is fixedly connected to the bottom of the upper clamp 12. A third motor 17 is fixedly connected to the outside of the workbench 1. The third motor 17 is the power source of the positioning mechanism and drives the rotating shaft 18 to rotate. The rotating shaft 18 is fixedly connected to one side of the output shaft of the third motor 17.

[0021] like Figure 1 as well as Figure 2 As shown, a PLC processor 20 is fixedly connected to the upper side of the workbench 1. The PLC processor 20 serves as the control core, coordinating the actions of each motor to achieve automated operation. The PLC processor 20 is also connected to the first motor 3, the second motor 8, and the third motor 17 via communication.

[0022] The working principle of this utility model is as follows: This automotive duct cutting device achieves precise fixing and efficient cutting of the duct through the coordinated operation of the rapid positioning mechanism and the cutting mechanism. During operation, the duct to be processed is first placed on the upper side of the lower clamp 11. Then, the third motor 17 is started by the PLC processor 20, which drives the rotating shaft 18 to rotate, tightens the connecting rope 19, and pulls down the upper clamp 12. This overcomes the force of the spring 14 of the rebound mechanism, and quickly presses and fixes the duct between the upper clamp 12 and the lower clamp 11. After positioning is completed, the first motor 3 is started, driving the lead screw 4 to rotate in the slide groove 2, which drives the slider 5 and the upper part of the mounting plate 6 and connecting plate. The structure 7 moves smoothly along the slide 2 to the predetermined cutting position. Then, the second motor 8 works, driving the rotating rod 9 and the cutting blade 10 mounted on it to rotate at high speed, precisely cutting the fixed air duct. After cutting, each component resets according to the command. The third motor 17 reverses to release the connecting rope 19. The upper clamp 12 automatically rises under the rebound of the tension spring 14, releasing the processed air duct. At the same time, the cutting mechanism stops working and returns to the initial position, ready for the next operation. The whole process is uniformly coordinated and controlled by the PLC processor 20, realizing the automated cycle of positioning, cutting, and releasing, ensuring processing efficiency and cutting quality.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
