[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a pull rod cutting machine with a clamping structure, including a base 1, a movable frame 2 connected to the top of the base 1 via a rotating shaft, a blade holder 3 installed on one side of the movable frame 2, a cutting blade 4 installed in the middle of the blade holder 3, the cutting blade 4 being fixed to the middle of the blade holder 3 by bolts, a motor 5 for driving the cutting blade 4 to rotate connected to one side of the movable frame 2, a fixed seat 6 also installed on the top of the base 1, and a through hole in the middle of the fixed seat 6 for placing the pull rod.
[0027] In use, the pull rod to be cut can be placed in the fixing seat 6 and then fixed. At this time, the motor 5 drives the cutting blade 4 in the blade holder 3 to rotate. Then, the handle on one side of the blade holder 3 is used to pull the blade holder 3 down, and the cutting blade 4 in the blade holder 3 can cut the pull rod.
[0028] like Figure 1 , Figure 2 and Figure 5 As shown, a groove is provided in the middle of the fixed base 6, and a connecting shaft 7 is provided inside the groove. A worm wheel 8 and a cam 23 are respectively installed on the outside of the connecting shaft 7. A worm 9 that passes through the fixed base 6 is meshed with the top of the worm wheel 8. The worm wheel 8 drives the cam 23 to rotate through the connecting shaft 7, and two sets of worm wheels 8 are symmetrically arranged about the through hole in the middle of the fixed base 6.
[0029] The tie rod to be cut can be placed in the fixed seat 6, then the cutting position of the tie rod can be adjusted, and then the worm 9 can be rotated so that the worm 9 drives the worm wheel 8 to rotate, thereby driving the cam 23 to rotate through the connecting shaft 7.
[0030] like Figure 3 and Figure 5As shown, a guide block 10 is provided on one side of the cam 23, and a guide rod 11 that passes through the fixed seat 6 is connected to one side of the guide block 10. The guide rod 11 can move in and out along the groove of the fixed seat 6. There are two sets of guide rods 11 symmetrically arranged about the center line of the fixed seat 6. A spring 12 is sleeved on the outside of the guide rod 11, and a pressure block 13 is installed at the bottom of the guide rod 11. A synchronous belt 14 is connected between the two sets of worm gears 9 through a pulley. The synchronous belt 14 is used to drive the two sets of worm gears 9 to rotate synchronously.
[0031] When the cam 23 rotates, it presses against the guide block 10 on one side. The guide block 10 is connected to the guide rod 11, and the guide rod 11 can only drive the pressure block 13 to extend and retract along the groove of the fixed seat 6. Therefore, the guide block 10 will press the pressure block 13 through the guide rod 11, so that the two sets of pressure blocks 13 are close to each other. At this time, the two sets of pressure blocks 13 can clamp and fix the pull rod in the fixed seat 6. When the worm gear 9 is rotated in the opposite direction, the cam 23 releases the pressure on the guide block 10. The guide rod 11 will drive the pressure block 13 to retract into the groove of the fixed seat 6 through the reset action of the spring 12, so that pull rods of different sizes can be clamped and fixed.
[0032] Furthermore, rotating one set of worm gears 9 will drive two sets of worm gears 9 to rotate synchronously through the timing belt 14 and pulley, thereby causing the pressure blocks 13 in the two sets of fixed seats 6 to move synchronously. Therefore, the two ends of the pull rod can be clamped and fixed synchronously, making the pull rod more stable during cutting.
[0033] like Figure 2 and Figure 4 As shown, a slag discharge port 15 for collecting waste residue is provided in the middle of the base 1. A fixed scraper 16 is installed in the middle of the slag discharge port 15. A baffle 17 is provided at the bottom of the fixed scraper 16. The baffle 17 can slide along the slag discharge port 15. A connecting rod 18 is installed through the base 1 on one side of the baffle 17.
[0034] The waste generated during the cutting of the tie rod will fall onto the baffle 17 of the slag discharge port 15. At this time, the baffle 17 can be pulled outward of the slag discharge port 15 by the connecting rod 18. When the baffle 17 moves, since the position of the fixed scraper 16 remains unchanged, the fixed scraper 16 can push the waste on the baffle 17 to move. When the baffle 17 and the fixed scraper 16 are misaligned, the waste on the baffle 17 will be pushed off the baffle 17 by the fixed scraper 16, thus facilitating the collection and cleaning of the waste.
[0035] like Figure 4 and Figure 6As shown, a locking block 19 is snapped into the top of the connecting rod 18, and a movable rod 20 is installed on the top of the locking block 19. A fixing block 21 is sleeved on the outside of the movable rod 20. The movable rod 20 can drive the locking block 19 to move up and down through the fixing block 21. The fixing block 21 is installed on one side of the base 1. A track is installed at the bottom of the base 1. A collection box 22 is slidably connected between the two sets of tracks. The collection box 22 can be slidably removed from the bottom of the base 1 through the track.
[0036] The movable rod 20 can be pulled upward along the fixed block 21, causing the movable rod 20 to drive the locking block 19 upward. The upward movement of the locking block 19 will move out of the slot at the top of the connecting rod 18, releasing the locking block 19 from limiting the connecting rod 18. Then, the baffle 17 can be pulled out from one side of the slag discharge port 15 through the connecting rod 18. Conversely, the baffle 17 can be pushed onto the slag discharge port 15, so that the slot at the top of the connecting rod 18 is aligned with the position of the locking block 19. At this time, the movable rod 20 will move downward under the action of gravity, and drive the locking block 19 to move into the slot of the connecting rod 18, thereby limiting the baffle 17 by the connecting rod 18.
[0037] Meanwhile, the collection box 22 can be removed from the bottom of the base 1 via the track, making it convenient to collect and clean the waste residue in the collection box 22. When the collection box 22 is connected to the bottom of the base 1, the waste residue falling from the slag discharge port 15 will fall into the collection box 22, thus making it convenient to collect and clean the waste residue generated by the cutting rod.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present application.
