[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses a frame cutting device for an electric tricycle. (See also...) Figure 1-4A frame cutting device for an electric tricycle includes a base 1. Two fixed frames 2 are fixedly connected to the upper surface of the base 1. Multiple conveying mechanisms for conveying frame tubing are installed inside the fixed frames 2. Each conveying mechanism includes multiple conveying rollers 3. Multiple rotating shafts 19 are rotatably mounted inside the fixed frames 2. Conveying rollers 3 are fitted onto the side walls of each rotating shaft 19. A drive motor 13 is installed at the top of the fixed frames 2. The drive motor 13 is connected to the multiple rotating shafts 19 via a drive assembly, which includes multiple worm gears 6 and multiple worm wheels 5. The top ends of each rotating shaft 19 movably penetrate the top wall of the fixed frames 2 and are fixedly connected to the worm wheels 5. Two mounting plates 14 are fixedly connected to the upper surface of the fixed frames 2. A connecting shaft 18 is rotatably mounted between the two mounting plates 14. Multiple worm wheels 5 that mesh with the worm gears 6 are fitted onto the side walls of the connecting shaft 18. The drive motor 13 is fixedly connected to one side of one of the mounting plates 14. The output end of the drive motor 13 is fixedly connected to one end of the connecting shaft 18. The threads on two adjacent worm gears 6 are in opposite directions. Two partitions 4 are fixedly connected to the inner side wall of the fixed frame 2. An inclined feeding groove 16 is provided on the right side of the upper surface of the base 1. A support plate 10 is fixedly connected to the upper surface of the base 1. Multiple support grooves 11 for supporting the frame tubing are evenly provided on the upper surface of the support plate 10. A bracket 7 is fixedly connected to the upper surface of the support plate 10. An electric telescopic rod 8 is fixedly installed in the middle of the upper surface of the bracket 7. A pressure plate 17 is fixedly connected to the output end of the electric telescopic rod 8. Multiple pressure grooves 20 that cooperate with the support grooves 11 are provided on the lower surface of the pressure plate 17. A cutting mechanism 15 for cutting the frame tubing is provided on one side of the bracket 7. A control module 12 is fixedly installed on one side of the base 1. The drive motor 13, the electric telescopic rod 8, and the cutting mechanism 15 are all electrically connected to the control module 12. The cutting mechanism 15 is existing technology and widely used in society, so it will not be described in detail.

[0020] The implementation principle of the frame cutting device for an electric tricycle in this application embodiment is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. When in use, after the drive motor 13 starts, it drives the worm gear 6 to rotate via the connecting shaft 18. The worm gear 6 meshes with the worm wheel 5, causing the rotating shaft 19 to rotate, which in turn drives the conveying roller 3 to rotate. The pipe is placed between two corresponding conveying rollers 3 and moves towards the support plate 10 under the action of friction. The adjacent worm gears 6 have opposite thread directions, allowing the symmetrically distributed conveying rollers 3 to rotate in opposite directions. The partition plate 4 divides the interior of the fixed frame 2 into multiple independent conveying channels, preventing mutual interference when multiple pipes are conveyed. When the pipe is conveyed above the support plate 10, the support groove 11 provides bottom support for the pipe. The control module 12 triggers the electric telescopic rod 8 to descend, and the pressure plate 17 moves downward accordingly. The pressure groove 20 cooperates with the support groove 11 to press the pipe tightly. The cutting mechanism 15 is driven by the control module 12 and moves along the axial direction of the pipe to complete the cutting. The feeding chute 16 is inclined, and the cut pipes slide down the chute to the collection area, reducing manual handling. Throughout the process, the control module 12 coordinates the timing of the drive motor 13, the electric telescopic rod 8, and the cutting mechanism 15 to achieve automated continuous production.

[0021] In this process, multi-channel conveying, modular positioning and automated cutting solve the problems of low efficiency and poor precision of traditional single spindle equipment. It is especially suitable for the mass production of electric tricycle frames for small and medium-sized enterprises, and has the advantages of high efficiency, precision, safety and low cost, and has significant industrial application value.
