[0011] Preferably, the two ends of the spring are fixed to the top end of the clamping frame and the top end of the moving block, respectively, and the spring and the moving block form a telescopic structure.

[0012] Preferably, the bottom end of the movable block is inserted into the interior of the guide groove, and a guide connection is formed between the movable block and the guide groove.

[0014] Preferably, two sets of threaded sleeves are provided, and the two sets of threaded sleeves form a threaded connection with the bidirectional screw.

[0015] The present invention provides a tube cutting device for electric vehicle frames, which has the following advantages: Equipped with an automatic feeding structure, when cutting tubing for electric vehicle frames, the guide seat and rack work together. Each time the pusher plate returns to its original position after pushing material and pushes material again, the rack drives the ratchet to rotate one revolution. By using a combination of ratchet and bevel gear, when the bevel gear rotates, the small gear will rotate through the cooperation of the rotating disk and the connecting disk. When the small gear rotates once, it will drive the large gear to rotate by one-sixth. When the large gear rotates by one-sixth, it will drive the cylinder to rotate by one-sixth, so that the placement groove is aligned with the material drop port at the bottom of the material box, allowing the pipe to fall into the placement groove for automatic material feeding, making it more convenient for pipe feeding and cutting. Furthermore, when the large gear rotates one-sixth of its length, it will drive the eccentric wheel to push the moving seat to reciprocate at the top of the fixed plate through the cooperation of the belt and the rotating rod. This causes the impact rod on one side of the moving seat to strike the side of the material box, vibrating the pipes inside the material box and preventing the pipes from accumulating and blocking inside the material box, thus completing the vibration work. Furthermore, when the impact rod moves, the guide sleeve is used to guide the impact rod, making it more stable during movement. Through the use of the above structure, the automatic feeding of pipes can be achieved without an additional power source or manual feeding, which not only saves operating costs but also improves feeding efficiency. With the clamping structure in place, when the pipe needs to be cut, the two-way screw and the screw sleeve work together to drive the first clamping plate on one side of the two sets of connecting plates to adhere to both sides of the pipe and perform a preliminary clamping of the pipe. Furthermore, when the first clamping plate clamps, the connecting plate pushes the connecting block into the interior of the clamping frame. The pressing block at its bottom end presses the moving block to move downward inside the guide groove, so that the second clamping plate at the bottom end of the moving block fits against the top of the pipe to complete the clamping again, thereby completing the multiple clamping work of the pipe and preventing the pipe from moving randomly during subsequent cutting. Furthermore, when the moving block is moving, the guide post can guide the moving block, making the moving block more stable during movement. Attached Figure Description

The automatic feeding structure 3 includes a cylinder 304, which is installed inside the fixed sleeve 6. A placement slot 305 is provided on the outer side of the cylinder 304. A large gear 309 is installed on one side of the fixed sleeve 6, with one end of the large gear 309 connected to one end of the cylinder 304. A small gear 308 is installed on one side of the large gear 309, with a connecting plate 307 installed at the front end of the small gear 308. A guide seat 301 is installed at the top of the mounting frame 2, and a rack 306 is installed at the top of the guide seat 301. A fixed frame 302 is installed at the top of the mounting frame 2 on one side of the guide seat 301. A bevel gear set 3018 is installed inside the fixed frame 302, with a ratchet 3017 installed at one end of the bevel gear set 3018 and a rotating disk 303 installed at the other end. A rotating rod 3010 is installed on one side of the top of the fixed sleeve 6, with one end of the rotating rod 3010... A belt 3011 is installed on the outside, and the belt 3011 is connected to one end of the large gear 309. An eccentric wheel 3012 is installed on the outside of the rotating rod 3010. A fixed plate 3015 is fixed on one side of the top of the fixed sleeve 6. A movable seat 3016 is installed on the top of the fixed plate 3015. An impact rod 3013 is fixed on one side of the movable seat 3016. A guide sleeve 3014 is sleeved on the outside of the impact rod 3013. The bottom end of the guide sleeve 3014 is fixed to the top of the fixed plate 3015. A guide connection is formed between the guide sleeve 3014 and the impact rod 3013. A moving component 8 is provided inside the worktable 1. The moving component 8 includes a lead screw 801. The lead screw 801 is installed inside the worktable 1. A threaded sleeve 802 is installed on the outside of the lead screw 801. A push plate 803 is installed on the top of the threaded sleeve 802. One side of the push plate 803 is fixed to one side of the rack 306. Reference Figures 1-9As shown: When cutting the tubing for the electric vehicle frame, the worker places the tubing into the material box 4. After placement, the external power supply starts the drive motor, which rotates the lead screw 801. During rotation, the lead screw 801, in conjunction with the lead sleeve 802, moves the push plate 803 to one side, thus pushing the tubing that has fallen into the holding rack 9. Each time the push plate 803 returns to its original position after pushing, during the return process, it pushes the rack 306 to move inside the guide seat 301. As the rack 306 returns to its original position, it drives the ratchet on the outside of the ratchet 3017 to rotate one revolution. Because the ratchet 3017... 17. With a special structural design, during feeding, the rack 306 drives the ratchet on the outside of the ratchet 3017 to rotate. When the ratchet on the outside of the ratchet 3017 rotates, the helical teeth on the inner wall of the ratchet will squeeze the pawl inside to retract inward, so that the pawl will not get stuck in the helical teeth inside the ratchet, allowing the ratchet on the outside of the ratchet 3017 to spin freely. When feeding is completed and the ratchet moves to its return position, the rack 306 drives the ratchet on the outside of the ratchet 3017 to reverse. At this time, the pawl inside the ratchet 3017, under the action of a spring on one side, gets stuck in the helical teeth on the inner wall of the ratchet on the outside of the ratchet 3017, driving the intermediate shaft of the ratchet 3017 to rotate, thereby driving the bevel gear set 3018 to rotate through the intermediate shaft of the ratchet 3017. When the ratchet 3017 rotates, it drives the bevel gear set 3018 to rotate. The bevel gear set 3018, in turn, drives the rotating disk 303 to rotate. The rotating disk 303, in turn, drives the connecting disk 307 to rotate. The connecting disk 307, in turn, drives the pinion 308 to rotate. When the pinion 308 rotates one revolution, it drives the large gear 309 to rotate one-sixth of its rotation. When the large gear 309 rotates one-sixth of its rotation, it drives the cylinder 304 to rotate one-sixth of its rotation, thus adjusting the placement slot 30. Aligning the 5th pinion with the bottom of the material box 4, the pipe falls into the placement groove 305 for automatic unloading. This achieves automatic unloading during the feeding and returning process. Once the returning process is complete, the pipe unloading is finished. When the large gear 309 rotates one-sixth of its length, it drives the rotating rod 3010 to rotate one revolution via the belt 3011. During rotation, the rotating rod 3010, in conjunction with the eccentric wheel 3012, pushes the movable seat 3016 to the top of the fixed plate 3015. A reciprocating motion, the moving seat 3016 pushes the impact rod 3013 to impact the pipes inside the material box 4, vibrating them and preventing the pipes from accumulating and clogging inside the material box 4, thus affecting the feeding. Furthermore, the guide sleeve 3014 guides the impact rod 3013 during movement, making it more stable. When pipe cutting is required, the push plate 803 is activated and pushed several times to allow the pipes to fall into the placement slot 305. When the placement slot 305 containing the pipes aligns with the top feed inlet of the holding rack 9, the pipes fall into the holding rack 9. At this point, the push plate 803 is activated to move the pipes to one side for cutting. Through the above structure, the push plate 803's return function during pipe cutting enables the feeding of pipes without the need for an additional power source or manual feeding, saving operating costs and improving feeding efficiency. A holding rack 9 is provided at the bottom of the fixed frame 6. A clamping structure 7 is provided on the other side of the top of the workbench 1. The clamping structure 7 includes a cutting frame 703, which is installed on one side of the top of the workbench 1. A cutting seat 704 is installed at the bottom of the inside of the cutting frame 703. A cylinder 701 is installed at the top of the cutting frame 703. A cutting machine 705 is installed at the bottom of the cylinder 701. A cutting blade 706 is installed at the output end of the cutting machine 705. A guide rod 702 is installed at the top of the cutting machine 705. A clamping frame 7010 is fixed at the top of the cutting seat 704 inside the cutting frame 703. Moving blocks 7016 are installed on both sides inside the clamping frame 7010. A second clamping plate 7017 is installed at the bottom of the moving blocks 7016. A guide groove 7018 is opened at the bottom of the clamping frame 7010. A guide post 7011 is installed at the top of the moving blocks 7016. A sleeve is provided on the outside of the guide post 7011. A spring 7015 is provided. A positioning plate 5 is installed on one side of the cutting frame 703. The two ends of the spring 7015 are fixed to the top of the clamping frame 7010 and the top of the moving block 7016, respectively. The spring 7015 and the moving block 7016 form a telescopic structure. The bottom end of the moving block 7016 is inserted into the interior of the guide groove 7018. The moving block 7016 and the guide groove 7018 form a guide connection. A bidirectional screw 707 is installed inside the cutting seat 704. Threaded sleeves 708 are installed on the outer sides of both ends of the bidirectional screw 707. A connecting plate 709 is fixed to the top of the threaded sleeve 708. A first clamping plate 7012 is installed on one side of the connecting plate 709. A connecting block 7013 is installed on the top of the connecting plate 709. A pressing block 7014 is installed at the bottom of the connecting block 7013. Two sets of threaded sleeves 708 are provided. The two sets of threaded sleeves 708 form a threaded connection with the bidirectional screw 707. Reference Figures 10-14 As shown: When the pusher plate 803 moves the pipe, the position of the positioning plate 5 installed at the top of the worktable 1 is adjusted to adjust the cutting length of the pipe, ensuring that the cutting length is consistent. When one end of the pipe abuts against one side of the positioning plate 5, the pusher plate 803 stops moving. At this time, the servo motor is started to drive the bidirectional screw 707 to rotate. When the bidirectional screw 707 rotates, it drives the two sets of threaded sleeves 708 to rotate, thereby pushing one side of the first clamping plate 7012 on one side of the connecting plate 709 at the top of the threaded sleeve 708 to adhere to both sides of the pipe for initial clamping. When plate 7012 completes the initial clamping, connecting plate 709 pushes connecting block 7013 into the interior of clamping frame 7010. At this time, pressing block 7014 at the bottom of connecting block 7013 presses moving block 7016 downward inside guide groove 7018. When moving block 7016 moves downward, it pulls spring 7015 to stretch, and the second clamping plate 7017 at the bottom of moving block 7016 fits against the top of the pipe to complete the second clamping, thus completing the multiple clamping work of the pipe and preventing the pipe from moving randomly during subsequent cutting. When the moving block 7016 moves, the guide column 7011 can guide the moving block 7016, making the moving block 7016 more stable during movement. After the pipe is clamped, the cylinder 701 is activated to move downward. When the cylinder 701 pushes downward, the cutting machine 705 is activated to drive the cutting blade 706 to rotate and cut the pipe. When the cylinder 701 pushes, the guide rod 702 can guide the cutting machine 705, making the cutting blade 706 more stable during movement or operation. When the rotating cutting blade 706 contacts the pipe, the shearing and cutting of the pipe is completed.
