[0002] The C-axis limiting mechanism in a direct-drive oscillating head plays a crucial role. This key component precisely limits the rotation range of the C-axis, ensuring stable and accurate operation within a pre-set angle range through effective constraint and control. Its significance lies in fully meeting the specific process requirements of various complex and diverse industrial processing and manufacturing workflows. In numerous high-precision production scenarios, this limiting mechanism plays an indispensable role, effectively guaranteeing the accuracy and quality of the production process with precise control and stable performance. It significantly reduces product errors and defects, providing a solid foundation and reliable guarantee for efficient production and high-quality output.
[0003] In existing C-axis limiting mechanisms, when the machining task or process changes, the mechanism with the fixed limiting angle cannot respond and adjust in a timely manner, resulting in low production efficiency and unstable machining quality. This fails to meet the market's requirement for direct-drive oscillating head equipment to quickly adapt to various complex machining needs, thus limiting its development in the field of high-precision, multi-variety machining. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a C-axis limiting mechanism for direct drive oscillating heads, aiming to improve the existing limiting mechanisms' ability to adapt to different processing requirements.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a C-axis limiting mechanism for a direct-drive oscillating head, comprising a fixing member, connecting plates fixedly connected to the top left and right sides of the fixing member, a fixing plate fixedly connected between the two connecting plates, second worm gears rotatably connected to the top and bottom of the fixing plate, two second motors fixedly connected to the left side of the right connecting plate, second worms fixedly provided at the output ends of the two second motors, and the two second worms meshing with their adjacent second worm gears, a connecting shaft provided at the top of the fixing member, a third motor fixedly connected to the bottom end of the connecting shaft, the output end of the third motor fixedly disposed between the fixing member and the fixing member, and a disassembly assembly provided on the opposite side of the two second worm gears, the disassembly assembly being used to release the limiting mechanism.
[0006] Preferably, the disassembly assembly includes a fixing seat, which is fixedly connected to the second worm gear. The fixing seat has a slot on its inner wall, a spring is fixedly connected to the bottom of the inner wall of the fixing seat, and a washer is fixedly connected to the top of the spring.
[0007] Preferably, a limiting post is provided at the top of the fixed base, and a connecting piece is fixedly connected to the bottom end of the limiting post.
[0008] Preferably, a rotating component is rotatably connected between the left and right sides inside the fixing component, and a connector is fixedly connected to the bottom of the rotating component.
[0009] Preferably, a first motor is fixedly connected to the right side of the fixing member, and a first worm gear is fixedly connected to the output end of the first motor.
[0010] Preferably, the front side of the first worm gear is engaged with a first worm wheel, and the left end of the first worm wheel extends through and into the interior of the fixing member.
[0011] Preferably, the first worm gear is rotatably connected to the fixed member, and the left end of the first worm gear is fixedly connected to the rotating member.
[0012] Preferably, two fixing rods are fixedly connected to the surface of the connecting shaft, and the two fixing rods are respectively located on opposite sides of the two second worm gears.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the second motor drives the second worm to rotate, thereby driving the two second worm wheels to rotate. When the two second worm wheels rotate, they will drive the limiting post to move.

At this time, the limiting post can be removed. When the limiting post is removed, the rotation of the bottom fixing part will not be blocked by the fixing rod, so the limiting can be released as needed to achieve rotation at any angle.

Detailed Implementation
[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a C-axis limiting mechanism for a direct-drive oscillating head, comprising a fixing member 1, connecting plates 7 fixedly connected to the top left and right sides of the fixing member 1, a fixing plate 20 fixedly connected between the two connecting plates 7, second worm gears 12 rotatably connected to the top and bottom of the fixing plate 20, two second motors 11 fixedly connected to the left side of the right connecting plate 7, a second worm 10 fixedly provided at the output end of each of the two second motors 11, and both second worm gears 10 meshing with their adjacent second worm gears 12, a connecting shaft 8 provided at the top of the fixing member 1, a third motor 13 fixedly connected to the bottom end of the connecting shaft 8, the output end of the third motor 13 fixedly provided between the fixing member 1, and a disassembly assembly provided on the opposite side of each of the two second worm gears 12, the disassembly assembly being used to release the limiting mechanism.
[0024] Specifically, the second motor 11 drives the second worm gear 10 to rotate, which in turn drives the two second worm wheels 12 to rotate. When the two second worm wheels 12 rotate, they drive the limiting post 14 to move. When the post moves to the required position, the second motor 11 stops rotating, and the two second worm wheels 12 are locked by the two second worm gears 10. When the third motor 13 at the top drives the fixing part 1 to rotate to a certain angle, the limiting post 14 is blocked by the fixing rod 9, thereby achieving the limiting. This allows the two second motors 11 to quickly adjust the limiting angle, flexibly adapting to different angle requirements.
[0025] Reference Figure 3 and Figure 4The disassembly assembly includes a fixed base 15, which is fixedly connected to the second worm gear 12. The inner wall of the fixed base 15 has a slot 18, and a spring 16 is fixedly connected to the bottom of the inner wall of the fixed base 15. A washer 17 is fixedly connected to the top of the spring 16.
[0026] Specifically, the bottom pad 17 and spring 16 can hold the connector 19 in place, so that when the connector 19 is inserted into the fixing seat 15 and rotates, the connector 19 is locked in the slot 18, thereby fixing the limiting post 14. Pressing the limiting post 14 to rotate it can remove the limiting post 14. When the limiting post 14 is removed, the rotation of the bottom fixing part 1 will not be blocked by the fixing rod 9, so the limiting can be released as needed to achieve rotation at any angle.
[0027] Reference Figure 4 The top of the fixed base 15 is provided with a limit post 14, and the bottom end of the limit post 14 is fixedly connected with a connector 19.
[0028] Specifically, by pressing and rotating the limiting post 14, the connecting piece 19 is rotated, thereby enabling the limiting post 14 to be quickly installed and removed.
[0029] Reference Figure 1 The left and right sides of the fixed part 1 are rotatably connected to the rotating part 2, and the bottom of the rotating part 2 is fixedly connected to the connector 3.
[0030] Specifically, when the fixed part 1 rotates, the rotating part 2 rotates within the fixed part 1, thereby allowing the bottom connector 3 to rotate to any angle, and the processing tool can be connected through the bottom connector 3 for use.
[0031] Reference Figure 1 The first motor 4 is fixedly connected to the right side of the fixing part 1, and the first worm gear 5 is fixedly connected to the output end of the first motor 4.
[0032] Specifically, the first motor 4 drives the first worm gear 5 to rotate. When the first motor 4 stops rotating, the first worm gear 5 will lock the first worm wheel 6 to prevent the rotating part 2 from rotating due to its own weight.
[0033] Reference Figure 1 The first worm 5 is meshed with the first worm wheel 6 on its front side, and the left end of the first worm wheel 6 passes through and extends into the interior of the fixing member 1.
[0034] Specifically, the first worm gear 6 is rotated to drive the rotating component 2 to rotate.
[0035] Reference Figure 1 The first worm gear 6 is rotatably connected to the fixed part 1, and the left end of the first worm gear 6 is fixedly connected to the rotating part 2.
[0036] Specifically, the first worm gear 6 rotates on the fixed part 1, and its left end is fixedly connected to the rotating part 2, thereby driving the rotating part 2 to rotate.
[0037] Reference Figure 2 Two fixing rods 9 are fixedly connected to the surface of the connecting shaft 8, and the two fixing rods 9 are located on opposite sides of the two second worm gears 12 respectively.
[0038] Specifically, the two fixing rods 9 cooperate with the two limiting posts 14 respectively, thereby limiting the rotation angle of the fixing part 1 at two angles.
[0039] Working principle: When the user operates, the first motor 4 drives the first worm 5 to rotate, which in turn drives the first worm wheel 6 to rotate the rotating part 2. When the first motor 4 stops rotating, the first worm 5 locks the first worm wheel 6 to prevent the rotating part 2 from rotating due to its own weight. The two second motors 11 at the top of the fixed part 1 drive the second worm 10 to rotate, which in turn drives the two second worm wheels 12 to rotate. After the limit post 14 is moved to the required position, the second motor 11 stops rotating, and the two second worm wheels 12 are locked by the two second worms 10. When the third motor 13 at the top drives the fixed part 1 to rotate to a certain angle, the fixed rod 9 will block the limit post 14 to achieve the limit.
[0040] If it is necessary to release the limit, press the limit post 14 to make it rotate, which will cause the connecting piece 19 to disengage from the slot 18, and the limit post 14 can be disassembled. At this time, the rotation of the fixing piece 1 will not be blocked by the fixing rod 9, thus achieving rotation at any angle. When the fixing piece 1 rotates, the rotating piece 2 can rotate inside the fixing piece 1. The bottom connecting head 3 can be connected to the processing tool and rotate to any angle to work.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
