Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a bevel cutting blade angle control device. Background Technology

[0002] In the field of cutting equipment technology, precise control of the cutting angle is crucial for ensuring cutting quality and meeting diverse production needs. Traditional beveling cutters have many shortcomings in angle control, making it difficult to meet the ever-increasing high-precision requirements of modern industry.

[0003] On the one hand, existing methods for adjusting the angle of a beveling cutter are often cumbersome, requiring operators to spend a significant amount of time and effort on adjustments. In some manually operated cutting equipment, operators rely on experience to estimate the cutting angle, which is not only inefficient but also entirely dependent on individual skill levels, making it difficult to guarantee consistency in the cutting angle each time. In mass production scenarios, this inconsistency can lead to product dimensional deviations, reduced product quality, increased scrap rates, and higher production costs.

[0004] On the other hand, most traditional beveling cutters lack precise angle measurement and positioning devices. Even those devices with angle adjustment functions often lack clear and accurate angle markings, making it difficult for operators to know the actual cutting angle and thus impossible to achieve precise control. In industries with extremely high precision requirements for cutting angles, such as woodworking for high-end furniture and metalworking for manufacturing precision parts, this lack of precision severely limits product quality and production efficiency, failing to meet the demands of the high-end market.

[0005] Furthermore, some traditional beveling blades have inadequate structural design, resulting in poor blade stability after angle adjustment. During cutting, the blade is prone to wobbling or displacement, causing the cutting trajectory to deviate from the predetermined path and further affecting cutting accuracy. Therefore, developing a simple-to-operate, precisely adjustable, and reliable beveling blade angle control device is urgently needed to address these problems in existing technologies, meet the high-precision cutting needs of various industries, and improve production efficiency and product quality.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a bevel cutting blade angle control device, including a blade holder fixing frame 1, a connecting plate 2, a rotating plate 3, and a blade 4. The connecting plate 2 is welded to one side of the top of the blade holder fixing frame 1. A rotating rod 14 is connected to the center of the front of the blade holder fixing frame 1 via a bearing 20. One end of the rotating rod 14 is connected to the rotating plate 3 on the front of the blade holder fixing frame 1 via bolts. A connecting groove 6 is opened in the center of the surface of the rotating plate 3. A connecting slider 8 is slidably connected inside the connecting groove 6. A mounting bracket 9 is welded to the top of the connecting slider 8. The blade 4 is installed on the top surface of the mounting bracket 9 via bolts. A fixing plate 10 is welded to the side of the connecting slider 8. A rotating wheel 15 is installed on the back of the blade holder fixing frame 1 at one end of the rotating rod 14. A connecting bracket 17 is welded to one side of the back of the blade holder fixing frame 1. A scale 21 is glued to the middle of the rotating rod 14 on the back of the blade holder fixing frame 1.

[0027] Furthermore, the tool holder fixing frame 1 has an annular groove 19 on the front side, and an annular slider 5 is welded to the bottom of the rotating plate 3. The annular slider 5 is engaged and slidably connected with the annular groove 19, which makes the rotating plate 3 more stable during rotation and also ensures the firmness of the rotating plate 3 during use.

[0028] Furthermore, limiting grooves 7 are provided on the inner walls of both sides of the connecting groove 6, and the two sides of the connecting slider 8 are engaged and slidably connected with the limiting grooves 7, so as to facilitate the adjustment of the position of the connecting slider 8, that is, to make adaptive adjustment of the position of the blade 4.

[0029] Furthermore, the rotating plate 3 has a number of fixing screw holes 11 evenly distributed on its surface. The fixing screw holes 11 are arranged in a row on the side of the connecting groove 6. The fixing plate 10 is fixedly connected to the fixing screw holes 11 by fixing bolts 12, which facilitates the fixing of the adjusted connecting slider 8.

[0030] Furthermore, an indicator needle 13 is welded to the surface of the rotating rod 14 and the dial 21 to facilitate observation of the rotation angle of the rotating plate 3.

[0031] Furthermore, the rotating wheel 15 has several fixing holes 16 evenly distributed on its side. The wing bolts 18 are fixedly connected to the corresponding fixing holes 16 to facilitate the fixing of the rotating wheel 15, that is, to limit and fix the rotation angle of the rotating plate 3.

[0032] Working Principle: Angle Adjustment: When adjusting the cutting angle of the bevel cutter, first operate the rotating wheel 15. Since the rotating wheel 15 is mounted at one end of the rotating rod 14, which is connected to the tool holder bracket 1 via the bearing 20, it has good rotational flexibility. Loosen the wing bolt 18; at this point, the rotating wheel 15 is no longer fixed and can rotate around the axis of the rotating rod 14. As the rotating wheel 15 rotates, the rotating rod 14 rotates synchronously, and the connected rotating plate 3 also rotates accordingly. During this process, the annular slider 5 at the bottom of the rotating plate 3 slides within the annular groove 19 on the front of the tool holder bracket 1, ensuring the stability of the rotating plate 3's rotation and preventing wobbling or offset.

[0033] Angle observation and precise positioning: As the rotating plate 3 rotates, the indicator needle 13 welded to the surface of the rotating rod 14 rotates along with the rotating rod 14. The indicator needle corresponds to the scale 21 on the back of the tool holder bracket 1. The operator can accurately know the rotation angle of the rotating plate 3 by observing the position of the indicator needle 13 on the scale 21, thereby achieving precise adjustment of the cutting angle. When the rotating plate 3 rotates to the required angle, the rotating wheel 15 is stopped from rotating, and then the wing bolt 18 is tightened so that it is inserted into the corresponding fixing hole 16 on the side of the rotating wheel 15 to fix the rotating wheel 15, thereby locking the angle of the rotating plate 3 and completing the initial setting of the cutting angle.

[0034] Blade position fine-tuning: If further adjustment of the blade 4's position is required, it can be achieved through the connecting slider 8. Limiting grooves 7 are formed on the inner walls of both sides of the connecting groove 6, and the two sides of the connecting slider 8 engage and slide with the limiting grooves 7. According to actual cutting requirements, manually slide the connecting slider 8 to move it along the limiting grooves 7 within the connecting groove 6. A mounting bracket 9 is welded to the top of the connecting slider 8, and the blade 4 is mounted on the mounting bracket 9. Therefore, the movement of the connecting slider 8 will cause the blade 4 to move together, thereby adjusting the position of the blade 4 on the rotating plate 3, achieving fine-tuning of the blade position.

[0035] Fixed connecting slider: After the position of the blade 4 is adjusted, a fixed connecting slider 8 is needed to ensure that the blade 4 does not shift during the cutting process. Several fixing screw holes 11 are evenly distributed on the surface of the rotating plate 3. The fixing plate 10 welded to the side of the connecting slider 8 is fixedly connected to the fixing screw holes 11 by fixing bolts 12. Select appropriate fixing screw holes 11 and tighten the fixing bolts 12 to firmly fix the fixing plate 10 to the rotating plate 3, thereby ensuring the stability of the blade 4's position during cutting. After completing the above operations, the bevel cutting angle control device can perform cutting operations at the set angle. During the cutting process, the stable structural design ensures the accuracy and quality of the cutting.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
