Description

Technical Field

[0001] This utility model relates to the field of two-degree-of-freedom platform equipment technology, specifically a two-degree-of-freedom platform based on an electric cylinder. Background Technology

[0002] A two-degree-of-freedom platform is a mechanical system capable of moving in two independent directions. It is widely used in precision positioning, simulation testing, ship motion simulation and other fields. Its core design achieves translational or rotational motion in a plane through different driving methods (such as piezoelectric stacks, hydraulic cylinders, gears and worm gears, etc.). However, current two-degree-of-freedom platforms based on electric cylinders have the following problems: they are inconvenient to rotate and control, and often adopt a fixed design, which makes it impossible to change directions, resulting in poor flexibility. Utility Model Content

[0003] The purpose of this invention is to provide a two-degree-of-freedom platform based on an electric cylinder to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a two-degree-of-freedom platform based on an electric cylinder, comprising a two-degree-of-freedom adjustment structure, a support base, and a stepper motor. The two-degree-of-freedom adjustment structure is fixedly mounted on the support base, and the stepper motor is located at the lower end of the support base. The support base is fixedly connected to the support base.

[0005] The stepper motor drives the second gear to rotate, and the second gear drives the first gear to rotate on the bearing ring through the first gear. The upper end of the gear disk is fixed to the two-degree-of-freedom adjustment structure.

[0006] The two-degree-of-freedom adjustment structure is used for two-degree-of-freedom adjustment. The electric cylinder extends and retracts, causing the platform plate to swing around the ball seat. The two-degree-of-freedom adjustment is controlled by electric cylinders in two directions.

[0007] Specifically, a bearing ring is rotatably provided on the support base, and a gear disk is rotatably provided on the upper end of the bearing ring. The gear disk meshes with a first gear, the first gear meshes with a second gear, and the lower end of the second gear is connected to a stepper motor. The stepper motor, the second gear, and the support base are connected in a continuous manner.

[0008] Specifically, the two-degree-of-freedom adjustment structure includes a platform plate, a ball seat, a first docking hinge, an electric cylinder, a second docking hinge, and a support chassis. The second docking hinge is fixedly connected to the support chassis, and an electric cylinder is hinged to the second docking hinge. The upper end of the electric cylinder is hinged to the first docking hinge, and the upper end of the first docking hinge is fixedly connected to the platform plate. The center of the platform plate is rotatably connected to the ball seat through a ball.

[0009] Specifically, the lower end of the supporting chassis is fixed to the gear plate, and the two electric cylinders are arranged at a 90-degree angle.

[0010] Specifically, the second gear is not connected to the supporting chassis. The second gear controls the rotation of the gear plate through the first gear, and the gear plate controls the rotation and adjustment of the supporting chassis.

[0011] Specifically, the gear disc, the first gear, and the second gear constitute a speed reduction mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By installing a support base, the support base can support the support seat, and the stepper motor controls the second gear to rotate. The second gear drives the gear plate to rotate through the first gear. The upper end of the gear plate is fixed to the two-degree-of-freedom adjustment structure. The gear plate drives the two-degree-of-freedom adjustment structure to rotate and adjust, thereby adjusting the angle of the two-degree-of-freedom adjustment structure, which facilitates flexible adjustment.

[0014] 2. By installing a two-degree-of-freedom adjustment structure, the supporting chassis and the gear plate inside the two-degree-of-freedom adjustment structure are fixed. The gear plate drives the supporting chassis to rotate, so that the two-degree-of-freedom adjustment structure rotates as a whole.

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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a two-degree-of-freedom platform based on an electric cylinder, including a two-degree-of-freedom adjustment structure 1, a support base 2 and a stepper motor 3. The two-degree-of-freedom adjustment structure 1 is fixedly installed on the support base 2, and the stepper motor 3 is located at the lower end of the support seat 7. The support seat 7 is fixedly connected to the support base 2.

[0021] Stepper motor 3 drives second gear 6 to rotate, and second gear 6 drives first gear 5 to rotate on bearing ring 8 through first gear 5. The upper end of gear disk 4 is fixed to two-degree-of-freedom adjustment structure 1. By installing support base 2, support base 2 can support support seat 7. Stepper motor 3 controls second gear 6 to rotate, and second gear 6 drives gear disk 4 to rotate through first gear 5. The upper end of gear disk 4 is fixed to two-degree-of-freedom adjustment structure 1. Gear disk 4 drives two-degree-of-freedom adjustment structure 1 to rotate and adjust, thereby adjusting the angle of two-degree-of-freedom adjustment structure 1, which facilitates flexible adjustment.

[0022] The two-degree-of-freedom adjustment structure 1 is used for two-degree-of-freedom adjustment. The electric cylinder 12 extends and retracts, causing the platform plate 9 to swing around the ball seat 10. The two-degree-of-freedom adjustment is controlled by the electric cylinder 12 in two directions.

[0023] A bearing ring 8 is rotatably mounted on the support base 7. A gear 4 is rotatably mounted on the upper end of the bearing ring 8. The gear 4 is meshed with the first gear 5. The first gear 5 is meshed with the second gear 6. The lower end of the second gear 6 is connected to the stepper motor 3. The stepper motor 3, the second gear 6 and the support base 7 are connected in a continuous manner.

[0024] The two-degree-of-freedom adjustment structure 1 includes a platform plate 9, a ball seat 10, a first docking hinge 11, an electric cylinder 12, a second docking hinge 13, and a support chassis 14.

The upper end of the electric cylinder 12 is hinged to the first docking hinge 11, and the upper end of the first docking hinge 11 is fixedly connected to the platform plate 9. The center of the platform plate 9 is rotatably connected to the ball seat 10 through a ball. By installing the two-degree-of-freedom adjustment structure 1, the support chassis 14 inside the two-degree-of-freedom adjustment structure 1 is fixed to the gear plate 4. The gear plate 4 drives the support chassis 14 to rotate, so that the two-degree-of-freedom adjustment structure 1 rotates as a whole. The electric cylinder 12 changes the position of the platform plate 9 by extending and retracting, so that the platform plate 9 swings and adjusts around the connection position of the ball seat 10, thereby performing two-degree-of-freedom adjustment.

[0025] The lower end of the supporting chassis 14 is fixed to the gear plate 4, and the two electric cylinders 12 are arranged at a 90-degree angle.

[0026] The second gear 6 is not connected to the supporting chassis 14. The second gear 6 controls the rotation of the gear disk 4 through the first gear 5, and the gear disk 4 controls the rotation and adjustment of the supporting chassis 14.

[0027] Gear 4, first gear 5, and second gear 6 constitute a speed reduction mechanism.

[0028] Working Principle: During use, the support base 2 provides support, and its upper end is fixed to the support seat 7. The stepper motor 3 controls the rotation of the second gear 6, which in turn drives the gear disk 4 to rotate via the first gear 5. The upper end of the gear disk 4 is connected to the two-degree-of-freedom adjustment structure 1, thereby causing the two-degree-of-freedom adjustment structure 1 to rotate. The gear disk 4 rotates on the bearing ring 8, thus causing the two-degree-of-freedom adjustment structure 1 to move as a whole. The lower end of the electric cylinder 12 is hinged to the second docking hinge 13, and the upper end of the electric cylinder 12 is hinged to the first docking hinge 11. The upper end of the first docking hinge 11 is fixed to the platform plate 9. By extending and retracting the electric cylinder 12, the platform plate 9 swings around the ball seat 10 connection position, thereby performing the two-degree-of-freedom adjustment. 2. The support base 2 can support the support seat 7, and the stepper motor 3 controls the second gear 6 to rotate. The second gear 6 drives the gear disk 4 to rotate through the first gear 5. The upper end of the gear disk 4 is fixed to the two-degree-of-freedom adjustment structure 1. The gear disk 4 drives the two-degree-of-freedom adjustment structure 1 to rotate and adjust, thereby adjusting the angle of the two-degree-of-freedom adjustment structure 1, which is convenient for flexible adjustment. By installing the two-degree-of-freedom adjustment structure 1, the support base 14 inside the two-degree-of-freedom adjustment structure 1 is fixed to the gear disk 4. The gear disk 4 drives the support base 14 to rotate, so that the two-degree-of-freedom adjustment structure 1 rotates as a whole. The electric cylinder 12 changes the position of the platform plate 9 by extension and retraction, so that the platform plate 9 swings and adjusts around the connection position of the ball seat 10, thereby performing the two-degree-of-freedom adjustment and completing the work.
