Description

Technical Field

[0001] This utility model relates to the field of milling cutter equipment technology, specifically to a milling cutter with an adjustable cutting angle. Background Technology

[0002] In modern mechanical manufacturing, milling is one of the key processes for forming parts. As the core tool for performing cutting tasks, the precise control of the cutting angle of the milling cutter plays a decisive role in machining quality and efficiency. With the manufacturing industry moving towards higher precision and complexity, the demand for various parts with complex curved surfaces and multi-dimensional structures is increasing. This requires milling cutters to flexibly adjust their cutting angles according to different machining needs to ensure optimal contact between the tool and the workpiece surface, achieving efficient and high-quality cutting. Whether in the manufacturing of precision parts in the aerospace field or in mold processing in the automotive industry, milling cutters with adjustable cutting angles have become essential equipment for improving machining accuracy and production efficiency.

[0003] Traditional milling cutters mostly have a fixed cutting angle design or only limited manual adjustment capabilities. When machining complex-shaped workpieces, these fixed-structure milling cutters often struggle to meet diverse cutting angle requirements, leading to uneven cutting forces, accelerated tool wear, and other problems. This not only affects machining accuracy and surface quality but also significantly shortens tool life and increases production costs. Manual adjustment is not only cumbersome and inefficient but also lacks precision, failing to meet the stringent requirements of modern intelligent manufacturing for machining efficiency and accuracy. Therefore, developing a milling cutter capable of quickly and accurately adjusting the cutting angle has become an urgent need to solve current machining challenges and drive technological upgrades in the manufacturing industry. To this end, we propose an adjustable-cutting-angle milling cutter. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an adjustable cutting angle milling cutter, thus solving the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an adjustable milling cutter, comprising an adjusting seat, a half-stroke worm gear fixedly connected to the bottom of the adjusting seat, arc-shaped limiting grooves on both sides of the bottom of the adjusting seat, an adjusting plate at the bottom of the adjusting seat, arc-shaped limiting sliders on both sides of the top of the adjusting plate, the bottom of the arc-shaped limiting sliders being slidably connected to the bottom of the inner wall of the arc-shaped limiting groove, a forward and reverse motor fixedly connected to one end of the bottom of the inner wall of the adjusting plate, a worm gear fixedly connected to one end of the forward and reverse motor via a connecting shaft, the end of the worm gear away from the forward and reverse motor being movably connected to one side of the bottom of the inner wall of the adjusting plate, and the worm gear being meshed with the bottom of the half-stroke worm gear.

[0006] Preferably, the top of the adjusting seat is provided with a fixed column, and a rotating seat is movably connected to the outer wall of the fixed column near the top end, with the top of the fixed column extending to the bottom of the inner wall of the rotating seat.

[0007] Preferably, a gear is fixedly connected to the top of the fixed column, and a second forward and reverse motor is fixedly connected to one side of the top of the inner wall of the rotating seat.

[0008] Preferably, a second gear is fixedly connected to the bottom rotating shaft of the second forward and reverse motor, and the second gear is meshed with the gear.

[0009] Preferably, the outer walls on both sides of the rotating seat are fixedly connected with a fixing perforated plate, and the top two ends of the fixing perforated plate have two parallel openings.

[0010] Preferably, a connecting seat is fixedly connected to the bottom of the adjusting plate, and a motor is fixedly connected to one end of the bottom of the adjusting plate near the connecting seat, with the motor close to the bottom of the inner wall of the connecting seat.

[0011] Preferably, the bottom rotating shaft of the motor extends to the bottom of the connecting seat, and a milling cutter head is fixedly connected to the bottom rotating shaft of the motor.

[0012] Compared with the prior art, this utility model provides a milling cutter with an adjustable cutting angle, which has the following beneficial effects:

[0013] 1. Compared to traditional fixed-angle milling cutters, this adjustable-angle milling cutter achieves high-precision angle adjustment through a unique mechanical structure. The half-stroke worm gear and worm at the bottom of the adjusting seat form a worm gear transmission. When the forward and reverse motors drive the worm gear to rotate, the half-stroke worm gear can achieve precise rotation within a limited angle. Combined with the guide and limiting functions of the arc-shaped limiting groove at the bottom of the adjusting seat and the arc-shaped limiting slider on the adjusting plate, the tilt angle error of the adjusting plate is controlled to a very small range, thus precisely adjusting the tilt angle of the milling cutter head. In the horizontal direction, the second forward and reverse motor drives the second gear to mesh with the gear at the top of the fixed column, enabling the rotating seat to rotate 360° around the axis of the fixed column, thereby driving the milling cutter head to complete the horizontal angle adjustment. This dual-dimensional precise adjustment structure allows the milling cutter to maintain the optimal cutting posture according to the curved contours of complex workpieces, avoiding the cutting deviations caused by the fixed angle of traditional milling cutters.

[0014] 2. Compared to traditional milling cutters, which require frequent tool changes or manual adjustments when facing multi-directional and multi-angle machining needs, severely impacting machining efficiency, this adjustable-angle milling cutter achieves rapid angle switching through an electrified and integrated mechanical structure. Both the forward and reverse motors and the second forward and reverse motor utilize high-torque servo motors, enabling adjustment of the milling cutter head's tilt and horizontal angles within seconds. The sliding engagement of the arc-shaped limit slider and arc-shaped limit groove between the adjustment plate and the adjustment seat, along with the movable connection structure between the rotating seat and the fixed column, ensures a smooth and stable angle adjustment process without any jamming.

[0015] 3. Compared to traditional fixed-angle milling cutters, which are prone to excessive localized stress and accelerated wear due to the inability to optimize the cutting angle, this adjustable-angle milling cutter effectively improves the stress state of the tool. The worm gear drive has a self-locking characteristic, preventing angle deviation after the milling cutter head tilt angle is adjusted to the correct position, ensuring stable force during cutting. Simultaneously, the fixed perforated plates on both sides of the rotary seat are rigidly connected to the machine tool, enhancing the stability of the entire milling cutter system and reducing cutting vibration. The direct-drive structure between the motor and the milling cutter head shortens the power transmission path, reducing energy loss and vibration transmission. These structural designs ensure uniform force on the cutting edge during cutting, lower cutting temperature, and slower wear rate. Attached Figure Description

Through gear transmission, the stability and accuracy of power transmission are ensured, and the precise adjustment of the angle of the milling cutter head 16 in the horizontal direction is realized to meet the processing requirements under different working conditions.

[0026] Furthermore, fixed opening plates 13 are fixedly connected to the outer walls on both sides of the rotary seat 9.

The parallel opening design facilitates installation and operation, ensures the stability of the milling cutter installation, and provides reliable support for the milling cutter during processing, reducing vibration and improving processing accuracy.

[0027] Furthermore, a connecting seat 14 is fixedly connected to the bottom of the adjusting plate 4, and a motor 15 is fixedly connected to one end of the bottom of the adjusting plate 4 near the connecting seat 14.

[0028] Furthermore, the bottom rotating shaft of the motor 15 extends to the bottom of the connecting seat 14, and the bottom rotating shaft of the motor 15 is fixedly connected to the milling cutter head 16.

[0045] 16. Milling cutter head 16: It rotates at high speed under the drive of motor 15 and uses the cutting edge to cut the workpiece, realizing the basic cutting function of the milling cutter. It is fixedly connected to the bottom rotating shaft of motor 15.

[0046] Working Principle: First, the overall tilt angle of the milling cutter is adjusted through the linkage of the forward and reverse motor 6, the half-stroke worm gear 2, and the adjusting plate 4. When the tilt angle of the milling cutter needs to be adjusted, the forward and reverse motor 6 (located at the bottom of the inner wall of the adjusting plate 4) is activated. The connecting shaft of the forward and reverse motor 6 drives the worm 7 to rotate (the end of the worm 7 away from the forward and reverse motor 6 is movably connected to one side of the bottom of the inner wall of the adjusting plate 4). Since the worm 7 and the half-stroke worm gear 2 are meshed at the bottom, and the half-stroke worm gear 2 is fixedly connected to the bottom of the adjusting seat 1, according to the worm gear transmission principle, the rotation of the worm 7 will drive the half-stroke worm gear 2 to rotate at a limited angle. The arc-shaped limiting sliders 5 on both sides of the top of the adjusting plate 4 are slidably connected to the bottom of the inner wall of the arc-shaped limiting groove 3 at the bottom of the adjusting seat 1. This limiting structure allows the adjusting plate 4 to slide stably along the arc-shaped limiting groove 3 under the drive of the half-stroke worm gear 2, thereby realizing the angle change of the adjusting plate 4 relative to the adjusting seat 1. Since the connecting seat 14 is fixedly connected to the bottom of the adjusting plate 4, and the motor 15 and the milling cutter head 16 are connected to the connecting seat 14, changing the angle of the adjusting plate 4 will drive the entire milling cutter head 16 to adjust its tilt angle, meeting the needs of different tilt cutting. Secondly, through the linkage of the second forward and reverse motor 11 with the gear 10 and the rotary seat 9, the horizontal rotation angle of the milling cutter is adjusted. When the horizontal rotation angle of the milling cutter needs to be adjusted, the second forward and reverse motor 11 (fixedly connected to the top side of the inner wall of the rotary seat 9) is activated. The rotating shaft at the bottom of the second forward and reverse motor 11 drives the second gear 12 to rotate. Because the second gear 12 is meshed with the gear 10 at the top of the fixed column 8, and the top of the fixed column 8 extends to the bottom of the inner wall of the rotary seat 9, with the outer wall of the fixed column 8 near the top movably connected to the rotary seat 9, the rotation of the second gear 12 will drive the gear 10 to rotate, thereby causing the fixed column 8 to rotate. Since the fixed column 8 is connected to the adjusting seat 1, and the adjusting seat 1 is in turn connected to the milling cutter head 16 through the aforementioned linkage, the rotation of the fixed column 8 will cause the entire adjusting seat 1 and the milling cutter head 16 to rotate horizontally around the axis of the fixed column 8, thereby realizing the angle adjustment of the milling cutter head 16 on the horizontal plane to adapt to cutting tasks in different directions. Finally, through the linkage between the motor 15 and the milling cutter head 16, the milling effect is achieved. After completing the above-mentioned adjustment of the tilt angle and horizontal rotation angle, the motor 15 (fixedly connected to the bottom of the adjusting plate 4 near the connecting seat 14 and close to the bottom of the inner wall of the connecting seat 14) is started. The rotating shaft at the bottom of the motor 15 drives the milling cutter head 16 to rotate at high speed, and the cutting edge of the milling cutter head 16 is used to cut the workpiece.
