Description

Technical Field

[0001] This utility model relates to the field of clamping structures for main rib cutting blades, and more particularly to a quick-change clamping structure for main rib cutting blades. Background Technology

[0002] The clamping structure of the main rib cutting blade is a mechanical device used to securely install the cutting blade on the cutting equipment. Its core function is to accurately position and tightly fix the blade through specific mechanical forces (such as eccentric compression, spring preload, and jaw locking), ensuring that the blade does not shift, shake, or fall off when cutting the main rib. It is a key component to ensure the accuracy, safety, and efficiency of the cutting operation.

[0003] However, the current clamping structure of the main wire cutting blade has the following defects: First, the blade is inconvenient to disassemble and difficult to replace quickly, which affects the operating efficiency; second, it lacks protective design, which makes the blade susceptible to damage from external objects when it is idle, and workers are prone to accidental injury, resulting in insufficient safety.

[0004] In response to this technical problem, this application proposes a quick-change clamping structure for a main rib wire cutting blade. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-change clamping structure for main wire cutting blades. This structure aims to facilitate blade disassembly and replacement, enabling rapid blade replacement and preventing damage from impacts by external objects when the blade is idle or injury from accidental collisions by workers, thereby improving blade safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-change clamping structure for cutting main rib wire blades includes a vertical rod, a blade is provided on the bottom side of the vertical rod, an insert block is fixedly connected to the top side of the blade, a slot is opened on the bottom side inside the vertical rod, the insert block is inserted into the slot, a clamping assembly is provided inside the vertical rod to clamp and fix the blade, two positioning grooves are opened on both the left and right sides of the blade, and a protective assembly is provided on the outer wall of the vertical rod to protect the blade.

[0008] Furthermore, the clamping assembly includes a slider that is slidably connected inside the upright, and two clamping arms are rotatably connected to both the left and right sides of the slider, with a through groove in the middle of the clamping arms.

[0009] Furthermore, four limiting rods are fixedly connected inside the upright, and the limiting rods are located inside the through groove. A clamping block is fixedly connected to the bottom end of the clamping arm, and the clamping block is engaged inside the positioning groove.

[0010] Furthermore, the inside of the upright is rotatably connected to a threaded rod, the inside of the slider is threadedly connected to the inside of the threaded rod, and the top side inside the upright is rotatably connected to a rotating rod.

[0011] Furthermore, bevel gears are fixedly connected to the left end of the rotating rod and the top end of the threaded rod, and the two bevel gears mesh with each other. A knob is rotatably connected to the right side of the upright rod via a damping shaft, and the right end of the rotating rod is fixedly connected inside the knob.

[0012] Furthermore, the protective assembly includes protective shells rotatably connected to the left and right sides of the upright, with fixing plates fixedly connected to the left and right sides of the bottom of the protective shells, and the bottom sides of the two protective shells magnetically connected.

[0013] Furthermore, a rod is inserted between the upper and lower fixing plates, and a brush plate is fixedly connected to the top of the rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the slider is driven by the threaded rod to slide, which causes the slider to move the clamping arm up and down. Under the restriction of the limiting rod, the clamping arm will rotate around the limiting rod. When the slider slides down, the clamping arm will unfold, so that the clamping block will disengage from the positioning groove. When the slider slides up, the clamping arm will close, so that the clamping block will engage in the positioning groove. This makes it easy to disassemble and replace the blade, and allows for quick blade replacement.

[0016] 2. In this utility model, the protective shell is rotated to the side of the blade, thereby protecting the blade and preventing it from being damaged by external objects when it is not in use or from being injured by workers accidentally bumping into the blade, thus improving the safety of the blade. At the same time, the brush plate on the plug can be used to clean the blade to prevent debris or dust and other impurities from affecting its performance. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a quick-change clamping structure for cutting main rib wire blades, including a vertical rod 1. An external driving device, such as an XYZ platform, is connected to the top side of the vertical rod 1 to move the vertical rod 1. A blade 8 is provided on the bottom side of the vertical rod 1, and a plug 16 is fixedly connected to the top side of the blade 8. A slot is provided on the bottom side inside the vertical rod 1, and the plug 16 is inserted into the slot. By inserting the plug 16 into the slot, the blade 8 is initially installed onto the vertical rod 1. Two positioning slots 15 are provided on both the left and right sides of the blade 8. A slider 11 is slidably connected inside the upright 1. Two clamping arms 7 are rotatably connected on both the left and right sides of the slider 11. A through slot is provided in the middle of the clamping arms 7. Four limiting rods 10 are fixedly connected inside the upright 1. The limiting rods 10 are located inside the through slot. A clamping block 9 is fixedly connected to the bottom end of the clamping arm 7. The clamping block 9 is engaged inside the positioning slot 15. A threaded rod 12 is rotatably connected inside the upright 1. The slider 11 is threadedly connected inside the threaded rod 12. A rotating rod 14 is rotatably connected to the top side inside the upright 1. A bevel gear 13 is fixedly connected to the left end of the rotating rod 14 and the top end of the threaded rod 12. The two bevel gears 13 mesh with each other. A knob 2 is rotatably connected to the right side of the upright 1 through a damping shaft. The right end of the rotating rod 14 is fixedly connected inside the knob 2. The damping shaft adopts a high-damping type to prevent the rotating rod 14 from rotating unexpectedly due to vibration generated during equipment operation. Rotating knob 2 causes the rotating rod 14 to rotate, which in turn causes the threaded rod 12 to rotate via two meshing bevel gears 13. The threaded rod 12 drives the slider 11 to slide, which in turn causes the clamping arm 7 to slide up and down. Under the restriction of the limiting rod 10, the clamping arm 7 rotates around the limiting rod 10. When the slider 11 slides down, the clamping arm 7 unfolds, causing the clamping block 9 to disengage from the positioning groove 15. When the slider 11 slides up, the clamping arm 7 closes, causing the clamping block 9 to engage in the positioning groove 15. This makes it easier to disassemble and replace the blade 8, allowing for quick replacement of the blade 8.

[0025] Reference Figure 1 and Figure 2The upright pole 1 is rotatably connected to the left and right sides of the protective shell 6. The bottom sides of the protective shell 6 are fixedly connected to the left and right sides of the bottom side. The bottom sides of the two protective shells 6 are magnetically connected. The upper and lower fixed plates 4 are inserted between the upper and lower fixed plates 4. The top of the inserted rod 5 is fixedly connected to the brush plate 3. By rotating the protective shell 6, the protective shell 6 is rotated to the side of the blade 8, thereby protecting the blade 8 and preventing it from being damaged by external objects when it is not in use or from being injured by workers accidentally bumping into the blade 8, thus improving the safety of the blade 8. When it is necessary to open the protective shell 6, rotate the protective shell 6 and then insert the inserted rod 5 between the upper and lower fixed plates 4, thereby fixing the two protective shells 6 together to prevent rotation. At the same time, the brush plate 3 on the inserted rod 5 can be used to clean the blade 8 to prevent debris or dust and other impurities from affecting its performance.

[0026] Working principle: First, insert the insert block 16 into the slot to initially install the blade 8 onto the upright 1. Then, turn the knob 2 to rotate the rotating rod 14, which in turn rotates the threaded rod 12 through two meshing bevel gears 13. This causes the threaded rod 12 to drive the slider 11 to slide upward, which in turn causes the clamping arm 7 to slide upward. Under the restriction of the limiting rod 10, the clamping arm 7 rotates around the limiting rod 10. When the slider 11 slides upward, the clamping arm 7 closes, thereby locking the clamping block 9 into the positioning groove 15, thus fixing the blade 8 onto the upright 1. The blade 8 can then be used. When the blade 8 is not in use, insert the insert rod 5 between the upper and lower fixing plates 4, and then use the brush plate 3 to clean the blade 8 to prevent debris or dust from affecting its performance. Then, rotate the protective shell 6 to one side of the blade 8 to provide protection, preventing the blade 8 from being damaged by external objects when not in use or from being injured by accidental collisions with the blade 8.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
