Description

Technical Field

[0001] This utility model relates to the field of beveling tools, specifically a beveling tool that can be adjusted at multiple angles. Background Technology

[0002] In woodworking, interior decoration, door and window installation, it is often necessary to cut materials such as boards, wood strips, and decorative lines at bevel angles to achieve splicing, joining, or decorative effects.

[0003] Current beveling tools mostly use a fixed angle, which is difficult to meet the needs of complex splicing. In addition, the tool is prone to shaking or displacement during the cutting process, which reduces the cutting accuracy and may cause safety hazards. Therefore, we propose a beveling tool with multi-angle adjustment. Utility Model Content

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] Example: Figures 1-5 As shown, this utility model discloses a multi-angle adjustable beveling tool, including a base 1, a side plate 2 fixedly connected to one side of the base 1, a limiting block 3 fixedly connected to one end of the side plate 2, an L-shaped plate 4 slidably connected to the outer periphery of the limiting block 3, an mounting block 5 fixedly installed on the upper outer side of the L-shaped plate 4, a worm gear 6 rotatably connected inside the mounting block 5, a limiting rod 7 detachably connected inside the worm gear 6, a rotating rod 8 fixedly connected to one end of the limiting rod 7, a mounting frame 9 fixedly connected to the outer periphery of the center end of the rotating rod 8, and a slider 11 slidably connected to the lower side of the mounting frame 9 via a slide rail 10.

[0016] Hydraulic rod 12 is fixedly installed on the upper end of the mounting frame 9. The output end of hydraulic rod 12 passes through the mounting frame 9 and is fixedly connected to slider 11. Connecting rods 26 are symmetrically fixedly connected on both sides of the lower end of slider 11. The slider 11 is driven to move up and down along slide rail 10 by hydraulic rod 12, which drives blade 14 to complete automatic descent cutting and descent reset. The operation is labor-saving and the cutting is stable.

[0017] The lower ends of the two connecting rods 26 are fixedly connected to the connecting seats 13. The blades 14 are fixedly connected to the inside of the two connecting seats 13 by bolts. The blades 14 are detachably connected to the connecting seats 13 by bolts, which facilitates quick replacement of blades of different specifications or wear, and adapts to the cutting needs of various materials such as wood, plastic, and metal.

[0018] The inner sides of both the side plate 2 and the L-shaped plate 4 are provided with a moving groove 15, which is rotatably connected to the blade 14. The inner sides of both the side plate 2 and the L-shaped plate 4 are provided with a number of blade grooves 16, which are slidably connected to the blade 14. The moving groove 15 is connected to the blade groove 16. The moving groove 15 and the blade groove 16 provide guiding space for the rotation and sliding of the blade 14, ensuring that it runs smoothly during angle adjustment and cutting, and avoiding jamming.

[0019] The worm gear 6 is connected to a worm 17 on its lower outer periphery. One end of the worm 17 passes through the mounting block 5 and is fixedly connected to a rotating wheel 18. An arc-shaped groove 19 is provided on the upper side of one side of the side plate 2. A scale 20 is provided on the upper end of the arc-shaped groove 19. By rotating the rotating wheel 18, the worm 17 drives the worm gear 6, thereby realizing the angle adjustment of the rotating rod 8 and the blade 14. The scale 20, together with the ruler 21, provides accurate angle readings and has high adjustment accuracy.

[0020] The mounting bracket 9 has a ruler 21 fixedly connected to one side through the arc groove 19. The base 1 has an empty groove inside. The upper surface of the base 1 has several material leakage holes 22. The lower end of one side of the L-shaped plate 4 has a through groove 23. The ruler 21 moves synchronously with the mounting bracket 9 and points to the angle value on the scale 20 to achieve intuitive reading. The material leakage holes 22 are used to guide the cutting debris to fall and avoid accumulation.

[0021] The lower outer side of the L-shaped plate 4 is fixedly connected to a collection box 24, and one side of the collection box 24 is connected to the leakage hole 22 through the through groove 23. A suction fan 25 is fixedly installed at the bottom of the collection box 24, and a collection frame 27 is slidably connected inside the collection box 24. A filter screen 28 is provided at the bottom of the collection frame 27. The suction fan 25 generates negative pressure, which sucks the debris into the collection box 24 through the leakage hole 22 and the through groove 23. The filter screen 28 intercepts the debris, and the air is discharged, thus realizing automatic dust removal and waste collection.

[0022] Working Principle: In use, first place the workpiece to be cut on the base 1, with one end against the side plate 2 as a positioning reference. According to the required cutting angle, manually rotate the rotating wheel 18. Through the meshing transmission of the worm gear 17 and worm wheel 6, this drives the rotating rod 8 and the mounting bracket 9 to rotate, thereby changing the tilt angle of the blade 14. The scale 21 on the mounting bracket 9 moves on the dial 20 as the angle changes, while the blade 14 rotates within the moving groove 15. The user can accurately read the current angle value to ensure accurate adjustment. After angle adjustment, activate the hydraulic rod 12. Its output end pushes the slider 11 downwards along the slide rail 10, causing the connecting rod 26, connecting seat 13, and blade 14 to descend synchronously, performing a bevel cut on the workpiece. During the cutting process, the blade 14 slides smoothly within the blade groove 16, ensuring smooth operation. The suction fan 25 at the bottom of the collection box 24 continuously operates, generating negative pressure airflow. This airflow draws cutting debris and dust through the discharge hole 22 on the base 1 into the internal slot, and then through the through-slot 23 on the side wall of the L-shaped plate 4 into the collection box 24. The debris is intercepted by the filter screen 28 at the bottom of the collection frame 27, and clean air is discharged, achieving efficient dust removal and centralized waste treatment. After cutting, the hydraulic rod 12 retracts, causing the slider 11 and blade 14 to rise and reset, ready for the next cutting operation. If adjustment to other angles is needed, the rotating wheel 18 can be rotated again, driving the worm gear mechanism to rotate the blade 14 within the moving slot 15, achieving continuous multi-angle adjustment, ready for the next cut. The user can slide out the collection frame 27 to empty the waste material for easy cleaning and maintenance. Furthermore, the L-shaped plate 4 can slide around the outer periphery of the limiting block 3 for easy disassembly and maintenance; the blade 14 is connected to the connecting seat 13 by bolts, allowing for quick replacement after wear.
