[0018] 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.

[0019] The purpose of this invention is to provide a cutting device to solve the problems existing in the prior art. It can adjust the cutting angle and cutting length, facilitate disassembly and assembly, improve work efficiency, reduce rework rate, improve work quality, and save construction costs.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] This utility model provides a cutting device, such as Figures 1-6As shown, the device includes a rotary cutting saw assembly and a limiting roller frame. The rotary cutting saw assembly includes a cutting saw 1, a rotating disc 4, a fixed base 5, a vertical baffle 6, and an abutment. The cutting saw 1 is fixedly connected to the rotating disc 4, and the rotating disc 4 is rotatably connected to the fixed base 5. The rotating disc 4 rotates around its own axis. The fixed base 5 is provided with an angle scale 22. The vertical baffle 6 is fixedly connected to the fixed base 5 and has a through groove for the blade 7 of the cutting saw 1 to pass through. The rotating disc 4 has a strip-shaped hole for the blade 7 of the cutting saw 1 to pass through. The fixed base 5 is provided with an abutment... The receiving part and the abutting part are used to abut the workpiece to be cut against the vertical baffle 6; the limiting roller frame includes a first frame 23, a limiting plate 24 and a plurality of rollers 25. One end of the first frame 23 is fixedly connected to the fixed base 5. Each roller 25 is rotatably mounted on the frame, and the rotation axis of the roller 25 is perpendicular to the length direction of the first frame 23. The vertical baffle 6 is parallel to the length direction of the first frame 23. The limiting plate 24 is slidably arranged in the length direction of the first frame 23. The first frame 23 has a scale 27 in the length direction. The limiting plate 24 is used to abut against one end of the workpiece to be cut. The rotating disc 4, in conjunction with the angle scale 22 on the fixed base 5, enables the cutting saw 1 to rotate precisely at an angle, ensuring the accuracy of the cutting angle and avoiding rework due to angle deviation. The limiting plate 24 and the scale 27 on the first frame 23 form an adjustable limiting mechanism. Workers only need to pre-set the position of the limiting plate 24 according to the scale to ensure that all workpieces have the same cutting length, achieving uniform size in batch operations. The dual precise control of angle and length improves processing quality and reduces rework rate and material waste caused by size discrepancies. The cutting operation process is simplified, omitting repeated measurement and marking steps, allowing even novice workers to quickly master the process and produce qualified products, reducing reliance on highly skilled workers. It is suitable for batch cutting and improves work efficiency. The roller 25 of the limiting roller frame reduces the pushing friction of long workpieces, making feeding smoother and more stable. The vertical baffle 6, combined with the abutment, firmly presses the workpiece, effectively preventing workpiece movement, shaking, or rebound during cutting, ensuring operational safety.

[0022] A further preferred embodiment of this utility model is, as follows: Figure 7As shown, the cutting device also includes a push roller frame, which comprises a second frame 29, multiple horizontal rollers 30, and multiple vertical rollers 31. One end of the second frame 29 is fixedly connected to the side of the fixed base 5 away from the first frame 23. Each horizontal roller 30 is rotatably connected to the second frame 29, and the rotation axis of the horizontal roller 30 is perpendicular to the length direction of the second frame 29. Each vertical roller 31 is fixedly connected to the side of the second frame 29 near the vertical baffle 6, and the rotation axis of the vertical roller 31 is perpendicular to the rotation axis of the horizontal roller 30. The push roller frame, as a push base, extends the total length of the worktable. The horizontal rollers 30 function identically to the rollers 25 on the limiting roller frame, supporting the weight of the workpiece and allowing the workpiece to be easily and with low friction pushed in the feed direction. The vertical rollers 31 provide support and positioning for the sides of the workpiece, enabling the sides of the workpiece to slide smoothly against these rollers during the pushing process.

[0023] In a further preferred embodiment of this utility model, the rotary cutting saw assembly also includes a locking component 17. The locking component 17 includes a spring locking button 20. The fixed base 5 has a locking hole, and the rotating disk 4 has multiple positioning holes circumferentially. One end of the spring locking button 20 can pass through the locking hole and insert into a positioning hole, thus fixing the fixed base 5 relative to the rotating disk 4. The locking component 17 is a component that enables quick switching between free rotation and fixed states. When the spring locking button 20 is pulled out, its internal spring is compressed, simultaneously causing a locking pin to disengage from the positioning hole of the rotating disk 4. This releases the mechanical connection between the rotating disk 4 and the fixed base 5, allowing free relative rotation. When the rotating disk 4 rotates to a certain angle, releasing the spring locking button 20 causes the internal spring to push the button and locking pin back to their original positions. The locking pin, under the spring force, engages in a positioning hole, fixing the fixed base 5 to the rotating disk 4.

[0024] In a further preferred embodiment of this utility model, the locking component 17 also includes a locking nut 21, and the fixed base 5 is provided with a locking hole. One end of the locking nut 21 can pass through the locking hole and abut against the outer surface of the rotating disk 4. The locking nut 21 is a component that securely locks the fixed base 5 and the rotating disk 4 together. The locking nut 21 has a handle or knurling for easy turning. When the locking nut 21 is tightened, it presses against the contact surfaces of the rotating base and the fixed base 5, increasing the friction between the rotating base and the fixed base 5, preventing relative rotation, and achieving rigid fixation.

[0025] A further preferred embodiment of this utility model is, as follows: Figure 8As shown, the abutment component includes a first top fastener 9, which comprises a fixed support 10, a threaded rod 11, and a top fixing plate 12. The fixed support 10 is fixedly connected to the fixed base 5 via a dovetail nut. The threaded rod 11 is threadedly connected to the fixed support 10. The top fixing plate 12 is fixedly connected to one end of the threaded rod 11. The axis of the threaded rod 11 is perpendicular to the vertical baffle 6. Rotating the threaded rod 11 drives the top fixing plate 12 to abut the workpiece to be cut against the vertical baffle 6. When the threaded rod 11 is rotated, the threaded transmission converts the rotational motion into the linear motion of the top fixing plate 12, causing the workpiece to be cut to abut against the vertical baffle 6. The clamping force can be flexibly adjusted by the rotation amplitude to adapt to workpieces of different thicknesses and materials. The threaded structure has self-locking properties; once tightened, the threaded rod 11 will not automatically loosen due to cutting vibration, ensuring that the workpiece to be cut always adheres to the vertical baffle 6 during processing, preventing displacement.

[0026] A further preferred embodiment of this utility model is, as follows: Figures 9-10 As shown, the abutment also includes a second top fastener 13, which includes a fixing collar 14, an outer cylinder 15, an inner abutment post 16, a locking member 17, and an adjusting handle. The fixing collar 14 is fixedly connected to the fixed base 5 by a dovetail nut. The outer cylinder 15 passes through the fixing collar 14 and can move relative to the fixing collar 14. The fixing collar 14 has a through hole, and the locking member 17 can pass through the through hole and abut against the outer cylinder 15, so that the locking member 17 and the outer cylinder 15 are relatively fixed. One end of the outer cylinder 15 has a U-shaped groove, and a connecting shaft is provided in the U-shaped groove. The adjusting handle includes an eccentric wheel 18 and a pressure rod 19. The pressure rod 19 is fixedly connected to the eccentric wheel 18. The eccentric wheel 18 is set on the connecting shaft. The outer cylinder 15 is sleeved outside the inner abutment post 16, and the inner abutment post 16 can move relative to the outer cylinder 15. By rotating the pressure rod 19, the eccentric wheel 18 can push the inner abutment post 16 to abut the workpiece to be cut against the vertical baffle 6. Loosening the locking element 17 allows the entire outer cylinder 15, along with its inner abutment 16 at the front end, to slide within the fixing ring 14. This accommodates workpieces of different sizes, expanding the processing range of the device. The pressure rod 19 drives the eccentric wheel 18 to rotate. During rotation, the outer edge of the eccentric wheel 18 pushes the inner abutment 16 towards the workpiece in a straight line, firmly pressing the workpiece against the vertical baffle 6. When the eccentric wheel 18 rotates in the opposite direction, the force pushing the inner abutment 16 disappears, and the inner abutment 16 loosens due to the elasticity or slight rebound of the workpiece, allowing for easy removal of the workpiece. From loosening to locking, only the pressure rod 19 needs to be moved, which is fast and suitable for batch production requiring frequent loading and unloading. Furthermore, the self-locking characteristic of the eccentric wheel 18 ensures that the clamping force will not fail even under vibration, making it safe and reliable.

[0027] In a further preferred embodiment of this utility model, the rotary cutting saw assembly also includes a support frame 8, and a fixed base 5 is fixed on the support frame 8.

[0028] In a further preferred embodiment of this utility model, a first height-adjustable support leg 28 is provided at the end of the first frame 23 away from the fixed base 5, and a second height-adjustable support leg 32 is provided at the end of the second frame 29 away from the fixed base 5. The heights of the first frame 23 and the second frame 29 can be adjusted using the height-adjustable support legs to accommodate support frames 8 of different heights.

[0029] In a further preferred embodiment of this utility model, the first frame 23 has a guide rail 26 along its length, the limiting plate 24 is slidably connected to the guide rail 26, and the limiting plate 24 and the guide rail 26 can be locked by the limiting fixing member 33.

[0030] In a further preferred embodiment of this utility model, the cutting saw 1 includes an adjustable protective cover, which includes a fixed protective cover 2 and a movable protective cover 3. The fixed protective cover 2 is rotatably connected to the movable protective cover 3 through a movable adjusting member. The fixed protective cover 2 is sleeved outside the adjustable protective cover. Rotating the movable protective cover 3 can adjust the overlap area between the fixed protective cover 2 and the movable protective cover 3, change the exposed area of ​​the blade 7, and achieve dynamic adaptation of the protection range.

[0031] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
