[0002] In the field of mechanical manufacturing, with increasingly diversified processing needs, higher requirements are being placed on the flexibility and precision of milling machine processing. Adjustable angle worktables for milling machines, thanks to their innovative design, can flexibly change the worktable angle, effectively expanding the processing range of milling machines, meeting the needs of complex angle processing tasks, and improving processing efficiency and quality. Therefore, there is a particular need for an adjustable angle worktable for milling machines.

[0003] Chinese patent CN221019703U, published on May 28, 2024, discloses an adjustable worktable for a milling machine. This allows for adjustment of the machining angle of the milling machine worktable, avoiding situations where the worktable's angle cannot adapt to different machining needs and thus has low practicality. By adjusting the machining angle of the milling machine worktable, its practicality is improved. However, after machining, metal chips and cutting waste are easily left in the gaps and corners of the worktable. The lack of an efficient cleaning structure makes manual cleaning time-consuming and labor-intensive, affecting the accuracy of subsequent machining and hindering long-term equipment maintenance.

[0020] 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.

[0021] Please see Figure 1-5This utility model provides a technical solution: an adjustable angle worktable for a milling machine, including a milling machine body 1, a mechanical arm 2 slidably connected to one side surface of the milling machine body 1, a milling cutter 3 provided on one side surface of the mechanical arm 2, a housing 4 fixedly connected to one side surface of the milling machine body 1, a base 5 fixedly connected to the lower surface of the housing 4, an electrical control cabinet 6 fixedly connected to the upper surface of the base 5, an adjustment mechanism 7 provided on the inner wall surface of the housing 4, and a worktable plate 8 provided on one side surface of the adjustment mechanism 7;

[0022] The control mechanism 7 includes a connecting plate 701, which is rotatably connected to the upper surface of the outer casing 4. The connecting plate 701 has a sliding groove 702. A rotating wheel 703 is rotatably connected to the inner wall surface of the sliding groove 702. A bracket 704 is rotatably connected to the rotating wheel 703. A brush 705 is rotatably connected to one side surface of the bracket 704. A handle 706 is wrapped around one side surface of the bracket 704. A pushing member 707 is fixedly connected to one side surface of the connecting plate 701. A push rod 708 is rotatably connected to one side surface of the pushing member 707. A sliding hole 709 is formed on one side surface of the push rod 708. The inner wall surface of the sliding hole 709... A sliding block 710 is slidably connected. A frame 711 is fixedly connected to the side surface of the sliding block 710 away from the push rod 708. A limit shell 712 is fixedly connected to one side surface of the frame 711. An eccentric wheel 713 is slidably connected to the inner wall surface of the frame 711. A motor 714 is rotatably connected to one side surface of the eccentric wheel 713. A limiting member 715 is slidably connected to the outer wall surface of the push rod 708. A limiting hole 716 is opened on one side surface of the limiting member 715. A rotating shaft 717 is rotatably connected to one side surface of the connecting plate 701. The connection is made through the connecting plate 701, the sliding groove 702, the rotating wheel 703, the bracket 704, and the brush 7. 05. The arrangement of the handle 706, pusher 707, push rod 708, sliding hole 709, sliding block 710, frame 711, limiting shell 712, eccentric wheel 713, motor 714, limiting component 715, limiting hole 716, and rotating shaft 717 is as follows: During use, after the motor 714 starts, it drives the eccentric wheel 713 to rotate. The eccentric wheel 713 performs eccentric motion within the frame 711. Under the limiting effect of the limiting shell 712, it drives the frame 711 to perform precise reciprocating linear motion. The frame 711 transmits the motion to the push rod 708 through the sliding hole 709 of the sliding block 710. It slides smoothly within the limiting hole 716 of the limiting member 715, thereby pushing the pushing member 707, causing the connecting plate 701 to rotate around the pivot 717, ultimately achieving the angle adjustment of the worktable 8. In terms of cleaning, the operator holds the handle 706, which drives the support 704 to move. The rotating wheel 703 rotates flexibly within the slide groove 702 of the connecting plate 701, allowing the brush 705 to cover all areas of the worktable 8. This reduces downtime for cleaning, ensures production continuity, avoids the impact of waste residue on subsequent processing accuracy, reduces equipment maintenance costs, and achieves efficient integration of processing and cleaning functions.

[0023] Furthermore, a worktable 8 is fixedly connected to the upper surface of the connecting plate 701. The connecting plate 701 is parallel to the outer shell 4. The rotating shaft 717 is fixedly connected to the side surface of the outer shell 4 near the connecting plate 701. Through the setting of the connecting plate 701, in use, the connecting plate 701 serves as the support of the worktable 8 and is rotatably connected to the rotating shaft 717. When the push rod 708 pushes the pusher 707, the connecting plate 701 can rotate around the rotating shaft 717 as a fulcrum, thereby causing the worktable 8 fixed above to change its angle. Since the connecting plate 701 is parallel to the outer shell 4, the stability and directionality of the rotation process are ensured.

[0024] Furthermore, two chute 702s of the same size are provided and symmetrically distributed along the central axis of the connecting plate 701. Two rollers 703 of the same size are also provided and symmetrically distributed along the central axis of the connecting plate 701. The inner wall dimensions of the two chute 702s match the outer wall dimensions of the rollers 703s. Through the arrangement of the chute 702s and rollers 703s, during use, the two symmetrically distributed chute 702s provide a rotation track for the rollers 703s. When the operator holds the handle 706 and moves the support 704, the support 704 drives the rollers 703s to roll within the chute 702s, allowing the brush 705 to move flexibly on the surface of the workbench 8. The symmetrically distributed chute 702s and rollers 703s enhance the stability of the support 704 during movement and reduce the shaking of the brush 705 during cleaning.

[0025] Furthermore, the vertical central axis of the push rod 708 intersects perpendicularly with the horizontal central axis of the limiting member 715. The outer wall dimension of the push rod 708 matches the inner wall dimension of the limiting hole 716. Two limiting members 715 of the same size are provided and are distributed in parallel on the inner wall surface of the outer shell 4. Through the setting of the push rod 708 and the limiting hole 716, during use, the frame 711 drives the push rod 708 to move through the sliding block 710. The outer wall of the push rod 708 is tightly fitted with the limiting hole 716 of the limiting member 715. The limiting hole 716 constrains the movement direction of the push rod 708, so that it can only slide in a straight line along the direction of the limiting hole 716, reducing the probability of it deviating or shaking during movement and improving the stability of the mechanism.

[0026] Furthermore, the inner wall dimensions of the sliding hole 709 match the outer wall dimensions of the sliding block 710, and the horizontal central axis of the sliding block 710 intersects perpendicularly with the vertical center line of the push rod 708. Through the arrangement of the sliding hole 709 and the sliding block 710, when the frame 711 moves during use, it drives the sliding block 710, which slides within the sliding hole 709 of the push rod 708. Through their cooperation, the linear motion of the frame 711 is transmitted to the push rod 708. The design of the matching dimensions of the sliding hole 709 and the sliding block 710 ensures the smoothness and accuracy of motion transmission and reduces friction and energy loss during the motion process.

[0027] Furthermore, two limiting shells 712 of the same size are provided and are symmetrically distributed along the frame 711. The frame 711, the eccentric wheel 713, and the limiting shells 712 are parallel to each other. With the setting of the limiting shells 712, when the eccentric wheel 713 rotates in the frame 711 during use, the limiting shells 712 distributed on both sides restrict the range of motion of the eccentric wheel 713, preventing the eccentric wheel 713 from leaving the frame 711. At the same time, it also guides and constrains the movement of the frame 711, ensuring that the frame 711 can only perform reciprocating linear motion, effectively improving the stability of the mechanism.

[0028] Furthermore, the outer wall dimensions of the eccentric wheel 713 match the inner wall dimensions of the frame 711. The motor 714 is fixedly connected to the inner wall surface of the outer casing 4. Through the arrangement of the eccentric wheel 713 and the motor 714, when in use, the motor 714 drives the eccentric wheel 713 to rotate after being powered on. The eccentric wheel 713 utilizes its eccentric characteristics to perform eccentric motion within the frame 711, converting the rotational motion of the motor 714 into the reciprocating linear motion of the frame 711, providing power for the angle adjustment of the worktable 8. The fixed motor 714 ensures the stable operation of the eccentric wheel 713, effectively improving the stability of the mechanism.

[0029] Working principle: When the angle of the worktable 8 needs to be adjusted, the motor 714 starts, driving the eccentric wheel 713 to rotate. Since the eccentric wheel 713 moves within the frame 711, its rotation causes the frame 711 to reciprocate. Simultaneously, the limiting shell 712 restricts the eccentric wheel 713 and the frame 711. The frame 711 is connected to the sliding hole 709 of the push rod 708 via the sliding block 710, thereby driving the push rod 708 to slide up and down along the limiting hole 716 of the limiting member 715. The pushing member 707 is rotatably connected to the push rod 708. The sliding of the push rod 708 pushes the pushing member 707, causing the connecting plate 701 to rotate around the pivot 717. Because the worktable 8 is fixed to... Above the connecting plate 701, when the connecting plate 701 rotates, the worktable 8 also changes its angle, realizing the adjustment of the processing angle. After processing, if it is necessary to clean the waste on the worktable 8, the operator can hold the handle 706 and drive the bracket 704 to move. The bracket 704 drives the rotating wheel 703 to rotate in the slide groove 702 of the connecting plate 701, so that the brush 705 can move on the surface of the worktable 8. By manually controlling the movement trajectory of the brush 705, the residual waste on the worktable can be cleaned. This completes the use process of an adjustable angle worktable for milling machines.
