[0015] (III) Beneficial Effects

[0016] By using an electric push rod, half gear, and rack, the oscillating head achieves linear reciprocating motion. Combined with the slider and guide frame, the movement trajectory of the rack is effectively constrained, improving stability during transmission and reducing displacement instability during oscillation. This effectively suppresses angle drift, ensuring consistent angles throughout multiple oscillation cycles and enhancing overall angle positioning accuracy. Precise control of the oscillation angle reduces the frequency of adjustments and calibrations required due to angle deviations during use, thereby reducing setup time and maintenance costs. It also lowers the risk of accidental deviation or impact under high-speed or high-load conditions.

[0017] By configuring the motor, lead screw, and displacement block, the displacement block can achieve precise up-and-down displacement along the axial direction of the lead screw. This improves the straightness and repeatability of the swing head's up-and-down adjustment, giving the swing head's up-and-down swing angle good controllability and repeatability. It also enhances the stability and accuracy of the swing head's angle adjustment in the vertical plane, reducing angle drift caused by unstable movement or positioning deviation. The integration of the left-and-right swing and up-and-down swing mechanisms into one unit results in a reasonable structural layout and coordinated cooperation among the components. This achieves multi-degree-of-freedom angle adjustment while ensuring the independence and stability of each direction of movement. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a head-swinging mechanism, such as Figure 1 - Figure 4 As shown, the technical solution includes a fixed frame 1, a frame 2 is provided in the inner cavity of the fixed frame 1, a round rod 10 is provided in the inner cavity of the frame 2, a half gear 12 is sleeved on the outer ring of the round rod 10, a swing head 3 is fixedly connected to one side of the half gear 12, a rack 13 is provided on one side of the half gear 12, an electric push rod 11 is fixedly installed on the inner wall of one side of the frame 2, and the output end of the electric push rod 11 is fixedly connected to one side of the adjacent rack 13.

[0026] The inner cavity of frame 2 is provided with two guide frames 14. The two ends of the guide frames 14 are fixedly connected to the inner walls of the adjacent frame 2 respectively. The inner cavity of the guide frame 14 is slidably connected to a slider 15. One side of the slider 15 is fixedly connected to one side of the adjacent rack 13. When the electric push rod 11 drives the rack 13 to perform horizontal reciprocating motion, the slider 15 slides synchronously in the guide frame 14, which effectively constrains the movement direction of the rack 13, prevents it from deviating during the movement, improves the linear motion stability of the rack 13, and thus ensures the smooth meshing between the rack 13 and the half gear 12.

[0027] Both ends of the round rod 10 are rotatably connected to the inner wall of the adjacent frame 2 via rotating shafts. The half gear 12 and the rack 13 mesh with each other through a toothed engagement. The half gear 12 rotates stably under the push of the rack 13. The round rod 10 serves as a support, providing a reliable fulcrum for the rotation of the half gear 12.

[0028] A mounting plate 4 is fixedly connected to the upper side of one side of the fixed frame 1, and a base plate 6 is fixedly connected to the lower side of one side of the fixed frame 1. A lead screw 8 is provided on one side of the fixed frame 1. A displacement block 7 is threaded onto the outer ring of the lead screw 8. One side of the displacement block 7 is rotatably connected to one side of the adjacent frame 2 through a rotating shaft. The motor 16 drives the lead screw 8 to rotate. The displacement block 7 moves up and down along the axial direction of the lead screw 8 under the action of the thread. This movement is transmitted to the frame 2 through the rotating shaft, causing the entire frame to swing. The mounting plate 4 and the base plate 6 provide a stable mounting reference and support structure for the lead screw 8, improving the load-bearing capacity and movement stability of the overall structure.

[0029] A motor 16 is fixedly installed on the top of the mounting plate 4. The top end of the lead screw 8 passes through the bottom of the mounting plate 4 and is fixedly connected to the output shaft of the motor 16. The bottom end of the lead screw 8 is rotatably connected to the top of the base plate 6 through a rotating shaft. The motor 16 provides the lead screw 8 with the power to rotate.

[0030] A limiting rod 9 is provided on one side of the lead screw 8. One end of the limiting rod 9 passes through the bottom of the adjacent displacement block 7 and is fixedly connected to the bottom of the mounting plate 4. The other end of the limiting rod 9 is fixedly connected to the top of the base plate 6. When the lead screw 8 rotates and drives the displacement block 7 to move up and down, the limiting rod 9 guides and prevents the displacement block 7 from rotating with the lead screw 8, ensuring that the displacement block 7 can only move linearly along the axis of the lead screw 8, thus ensuring the linear motion trajectory of the displacement block 7.

[0031] Two side plates 5 are fixedly connected to one side of the fixed frame 1. Both sides of the frame 2 are rotatably connected to one side of the adjacent side plate 5 through a pivot. The frame 2 swings relative to the side plate 5 with the pivot on both sides as the pivot point. The side plate 5 provides a stable and symmetrical support structure for this rotation, and provides a reliable pivot point for the frame 2, so that the frame 2 is evenly stressed and moves smoothly during the up and down swing.

[0032] Specifically: The electric push rod 11 is activated, and its telescopic motion drives the connected rack 13 to reciprocate linearly in the horizontal direction. During the movement of the rack 13, the slider 15 slides synchronously along the inner wall of the guide frame 14, effectively constraining the movement trajectory of the rack 13, preventing it from deviating, and ensuring the linearity and stability of the rack 13's movement. The rack 13 meshes with the half gear 12. As the rack 13 moves left and right, it drives the half gear 12 to perform forward and reverse rotation. The half gear 12 transmits the rotational motion to the swing head 3, enabling the swing head 3 to swing left and right in the horizontal plane. The motor 16 is activated, and the output shaft of the motor 16 drives the lead screw 8 to rotate. The lead screw 8 and the displacement... The screw block 7 is threaded and, under the guidance and constraint of the limit rod 9, allows the displacement block 7 to move linearly up and down along the axis of the screw 8. The up and down displacement of the displacement block 7 drives the frame 2, which is fixedly connected to it, to rise and fall synchronously. The two sides of the frame 2 are rotatably connected to the side plate 5 through the rotating shaft. When the frame 2 rises or falls, it rotates with the rotating shaft as the fulcrum, thereby driving the swing head 3 to swing up and down. By controlling the extension and retraction stroke of the electric push rod 11 and the number of rotations of the motor 16, the displacement of the rack 13 and the lifting height of the displacement block 7 can be precisely controlled, thereby achieving independent and precise control of the left and right and up and down swing angles of the swing head 3, meeting the needs of complex working conditions.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
