When machining automotive parts with multi-directional features, they have to frequently re-clamp the workpiece to adjust the machining angle. This repetitive positioning reduces production efficiency. When machining inclined structures of parts, the lack of an angle adjustment mechanism for the milling cutter requires manual repeated adjustment of the workpiece's spatial posture.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a multi-angle milling machine, including a machining table 1 for machining operations, a support frame 2 for supporting the machining table 1 fixedly connected to the lower end of the machining table 1, a cutting assembly 3 for machining parts installed on the upper surface of the machining table 1, a protective plate 4 for shielding the upper surface of the machining table 1, a clamping assembly 5 for fixing the parts installed on one side of the inner wall of the protective plate 4, and a collecting assembly 6 for collecting waste chips installed in the middle of the machining table 1.

[0024] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the cutting assembly 3 includes two first electric guide rails 301, which are fixedly connected to the upper end of the machining table 1 and are arranged symmetrically. A gantry frame 302 is mounted on the upper end of both first electric guide rails 301. A second electric guide rail 303 is mounted on one side of the gantry frame 302. A movable plate 304 is fixedly mounted on the side wall of the second electric guide rail 303. A hydraulic cylinder 305 is fixedly connected to the upper end of the movable plate 304. The output end of the hydraulic cylinder 305 passes through the movable plate 304 and is fixedly connected to a lifting device. Block 306 has a rotating groove 307 at its lower end. A worm gear 308 and a worm 309 are rotatably connected to the inner wall of the rotating groove 307. The worm gear 308 and the worm 309 mesh with each other. A baffle 310 is rotatably connected to the side wall of the lifting block 306 away from the gantry frame 302. The baffle 310 is fixedly connected to the end of the worm gear 308 away from the lifting block 306. A milling cutter 311 is fixedly installed on the side of the baffle 310 away from the lifting block 306. A first motor 312 is fixedly installed on one side of the lifting block 306. The output end of the first motor 312 passes through the lifting block 306 and is fixedly connected to one end of the worm 309.

[0025] Furthermore, the first electric guide rail 301 and the second electric guide rail 303 can drive the milling cutter 311 to move in the X and Y axis directions, and the hydraulic cylinder 305 can drive the milling cutter 311 to move in the Z axis direction, realizing the three-axis linkage of the milling cutter 311. The output end of the first motor 312 drives the worm gear 309 to rotate, and the worm wheel 308 rotatably connected to the inner wall of one side of the rotating groove 307 rotates, which makes the baffle 310 rotate, thereby realizing the adjustment of the angle of the milling cutter 311, improving the processing flexibility, enabling the milling cutter 311 to perform multi-angle processing operations on automotive parts, and improving processing efficiency.

[0026] Both the first electric guide rail 301 and the second electric guide rail 303 are existing technologies. They consist of a servo motor, a precision screw, a guide rail body, and a slider. The servo motor drives the precision screw to rotate. Through the threaded engagement between the screw and the nut inside the slider, the rotational motion of the motor is converted into the precise linear displacement of the slider along the guide rail body, realizing the controllable translational positioning of the components. Therefore, the gantry 302 is fixedly connected to the upper ends of the two sliders of the first electric guide rail 301, and the moving plate 304 is fixedly connected to one side of the slider on the second electric guide rail 303. It will not be described in detail here. The milling cutter 311 is a high-speed rotating carbide tool that cuts and removes material from the workpiece. The milling cutter generates a cutting speed of several thousand revolutions per minute under the drive of the main motor, so that the cutting edge can cut the surface of the part. It will not be described in detail here.

[0027] As one implementation method in this embodiment, such as Figure 3As shown, the clamping assembly 5 includes a mechanical chuck 501 and a second motor 502. The mechanical chuck 501 is rotatably connected to one side of the inner wall of the protective plate 4, and the second motor 502 is fixedly installed on the outer wall of the protective plate 4. The output end of the second motor 502 passes through the protective plate 4 and is fixedly connected to one side of the mechanical chuck 501.

[0028] Furthermore, before processing, the automotive parts can be fixed on the mechanical chuck 501. The mechanical chuck 501 is existing technology. Through multiple radially movable jaws inside the chuck, they can be manually adjusted to synchronously contract or expand towards the center. The carbide tooth surfaces or soft jaw gripping surfaces at the ends of the jaws form high-friction contact with the outer circle and inner hole of the part. At the same time, self-locking is achieved through a conical sleeve or screw mechanism to ensure that the part does not shift under high-speed rotation or cutting force. This will not be elaborated further here. After the mechanical chuck 501 fixes the part, the second motor 502 can drive the mechanical chuck 501 to rotate, thereby adjusting the machining surface of the part.

[0029] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 6 As shown, the collecting component 6 includes a chip discharge port 601 and a dust removal mechanism 602. The chip discharge port 601 is located in the middle of the processing table 1. The dust removal mechanism 602 is fixedly installed on one side of the upper end inside the support frame 2. Two sets of symmetrically arranged dust suction pipes 603 are fixedly connected to the inner wall of the chip discharge port 601. The dust suction pipes 603 are grouped in pairs. Each dust suction pipe 603 has multiple collection covers 604 connected to its side wall. The dust suction ends of the multiple collection covers 604 face upwards. The dust suction ends of the dust removal mechanism 602 are connected to a connecting pipe. The dust discharge ends of the four dust suction pipes 603 are all connected to the connecting pipe.

[0030] Furthermore, when the dust removal mechanism 602 is working, it generates suction and draws air through the collection hood 604, creating a negative pressure area inside the protective plate 4. This forms a directional airflow barrier during multi-angle machining, adsorbing the debris generated during machining and effectively preventing dust from entering the worm gear 308 and worm 309, thus avoiding debris accumulation that could affect the flexibility and accuracy of the milling cutter 311's angle switching. This provides a stable and clean environment for continuous machining. The dust removal mechanism 602 is existing technology. The dust removal device works on the principle of negative pressure suction. Small particles of debris and dust in the cutting area are captured by the high-speed airflow through the collection hood 604 and then intercepted by the cartridge filter. The clean air is discharged by the fan, and the collected small particles of debris and dust are centrally processed.

[0031] As one implementation method in this embodiment, such as Figure 3 and Figure 5As shown, two sets of symmetrically arranged support blocks 605 are fixedly connected to the inner wall of the chip discharge port 601. The support blocks 605 are arranged in pairs, and each support block 605 has a spring 606 and a telescopic rod 607 fixedly connected to its upper end. Each set of support blocks 605 has a grid plate 608 above it. The two grid plates 608 are symmetrically arranged and fixedly connected to the upper ends of four springs 606 respectively. The upper ends of four telescopic rods 607 are fixedly connected to the lower ends of two grid plates 608 respectively. The main pulley is fixedly sleeved on the outside of the output end of the second motor 502. 609. A rotating opening 610 is provided on one side of the processing table 1. A rotating rod 611 is rotatably connected to the inner wall of the chip discharge port 601. One end of the rotating rod 611 passes through the inner wall of the chip discharge port 601 and is rotatably set in the rotating opening 610. A pulley 612 is fixedly connected to one end of the rotating rod 611 located in the rotating opening 610. A transmission belt 613 is sleeved on the outside of the main pulley 609 and the pulley 612. Two symmetrically arranged elliptical plates 614 are fixedly connected to the outside of the rotating rod 611. The two elliptical plates 614 are respectively attached to the bottom of the two grid plates 608.

[0032] Furthermore, a grid plate 608 is installed above the collection cover 604 to block large pieces of cutting debris in real time and prevent the suction pipe 603 from clogging. During operation, the output end of the second motor 502 drives the mechanical chuck 501 to rotate, thereby adjusting the cutting surface of the part. At the same time, the output end of the second motor 502 drives the main pulley 609 to rotate. With the cooperation of the transmission belt 613, the pulley 612 rotates, causing the rotating rod 611 to rotate. The elliptical plate 614 on the outside of the rotating rod 611 strikes the bottom of the grid plate 608, and with the spring 606 resetting, it forms the vibration of the grid plate 608, automatically shaking off the debris accumulated on the surface of the grid plate 608, avoiding manual cleaning and machine downtime. At the same time, the vibration keeps the grid gaps of the grid plate 608 unobstructed, ensuring that the negative pressure dust collection efficiency is not affected by large particle residues.

[0033] As one implementation method in this embodiment, such as Figure 1 and Figure 6 As shown, a protective cover 7 is fixedly connected to the lower end of the processing table 1, and the protective cover 7 matches the chip discharge port 601.

[0034] Furthermore, the protective cover 7 can block and collect large pieces of debris falling from the chip discharge port 601, allowing the debris to fall into a designated area below the processing table 1, ensuring a clean processing environment, and facilitating the collection of debris by the user, thus reducing the workload of the staff.

[0035] Working principle: The first electric guide rail 301 and the second electric guide rail 303 can drive the milling cutter 311 to move in the X and Y axis directions, and the hydraulic cylinder 305 can drive the milling cutter 311 to move in the Z axis direction, realizing the three-axis linkage of the milling cutter 311. The output end of the first motor 312 drives the worm gear 309 to rotate, and the worm wheel 308, which is rotatably connected to the inner wall of one side of the rotating groove 307, rotates, which causes the baffle 310 to rotate, thereby realizing the adjustment of the angle of the milling cutter 311, improving the processing flexibility, and enabling the milling cutter 311 to perform multi-angle processing operations on automotive parts. When the dust removal mechanism 602 is working, the dust removal mechanism 602 generates suction, and the air is drawn out through the collection hood 604, so that the processing area inside the protective plate 4 forms a negative pressure area. During multi-angle processing, a directional airflow barrier is formed to adsorb the debris generated during processing, effectively preventing dust from entering the worm wheel 308 and worm gear 309, etc. The structure avoids the accumulation of debris affecting the flexibility and accuracy of the milling cutter 311 angle switching, providing a stable and clean environment for continuous processing. A grid plate 608 is installed above the collection cover 604 to block large cutting impurities in real time, preventing the suction pipe 603 from clogging. During operation, the output of the second motor 502 drives the mechanical chuck 501 to rotate, adjusting the cutting surface of the part. Simultaneously, the output of the second motor 502 drives the main pulley 609 to rotate. With the cooperation of the transmission belt 613, the pulley 612 rotates, causing the rotating rod 611 to rotate. The elliptical plate 614 on the outer side of the rotating rod 611 strikes the bottom of the grid plate 608, and with the spring 606 resetting, the grid plate 608 vibrates, automatically shaking off accumulated debris from its surface, avoiding manual cleaning and machine downtime. Simultaneously, the vibration keeps the grid gaps of the grid plate 608 clear, ensuring that the negative pressure suction efficiency is not affected by large particle residue.
