Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of electromechanical actuator technology, and more specifically, to an electromechanical actuator. Background Technology

[0002] Actuators are key components for implementing active vibration control and are an important part of active control systems. Also known as vibrators, actuators are used in dynamic experiments and serve as the power output device for these experiments.

[0003] Existing actuators are generally fixed in a fixed position. When connected to different machines for operation, they usually need to be disassembled and reinstalled due to the different heights of the interfaces, which is a waste of time.

[0004] In order to adjust the height of the interface, a search revealed a utility model patent with patent application number CN202120669619.7, which discloses an electromechanical actuator, including an actuator body, an upper clamping frame, a lifting column, and a lifting frame. The upper clamping frame is located on the upper end face of the actuator body, and a connecting column is fixedly connected to the upper end face of the upper clamping frame. A crossbar is fixedly connected to the upper end face of the connecting column, and the lifting column is fixedly connected to one end of the crossbar. The lifting column is located inside the lifting frame.

[0005] The aforementioned prior art allows the electromechanical actuator to rise or fall in the vertical direction during use, meeting work needs and adapting to different working environments; by setting buffer grooves and soft pads, the noise generated by vibration during operation of the electromechanical actuator is reduced, providing users with a quiet working environment.

The first moving mechanism is disposed on the clamping seat 8 and is used to drive the clamping block 9 to move within the clamping groove. The relative moving mechanism is disposed on the support frame 2 and is used to drive the two clamping seats 8 to move relative to each other. The relative moving mechanism includes a first threaded rod 10, a first cavity, and a first driving mechanism. The first threaded rod 10 is rotatably disposed within the support through hole 5 and passes through via a threaded engagement. The first cavity is located on the support frame 2. The first driving mechanism is disposed within the first cavity and is used to drive the two first threaded rods 10 to rotate synchronously. The first driving mechanism includes a first bevel gear 11, a second bevel gear 13, and a first handwheel 14. The first cavity side... A first bevel gear 11 is rotatably mounted on the wall. A first connecting rod 12 is fixedly mounted on and passes through the first bevel gear 11. The first connecting rod 12 passes through the side wall of the first cavity and is fixedly connected to the first threaded rod 10. A second bevel gear 13 is rotatably mounted on the inner top wall of the first cavity and meshes with the first bevel gear 11. A first handwheel 14 is rotatably mounted on the support frame 2. A second connecting rod is fixedly mounted between the first handwheel 14 and the second bevel gear 13. The rotation of the first handwheel 14 can drive the second bevel gear 13 to rotate. At the same time, the meshing of the second bevel gear 13 with the first bevel gear 11 drives the first connecting rod 12 and the first threaded rod 10 to rotate. This facilitates the relative movement of the clamping seat 8 through the threaded engagement between the first threaded rod 10 and the clamping seat 8, so that the side wall of the actuator body 4 can be clamped and fixed through the clamping seat 8.

[0063] Reference Figure 4 and Figure 5The first moving mechanism includes a second threaded rod 15, a second cavity, and a second driving mechanism. The second threaded rod 15 is rotatably disposed at the bottom of the clamping groove and extends into the clamping block 9 via a threaded engagement. The second cavity is opened within the clamping seat 8. The second driving mechanism is disposed on the clamping seat 8 and is used to drive the second threaded rod 15 to rotate. The second driving mechanism includes a third bevel gear 16, a fourth bevel gear 17, and a third driving mechanism. The third bevel gear 16 is rotatably disposed on the inner bottom wall of the second cavity and is fixedly connected to the second threaded rod 15. The fourth bevel gear 17 is rotatably disposed on the side wall of the second cavity. The third drive mechanism, meshing with the third bevel gear 16, is mounted on the support frame 2 and is used to drive the fourth bevel gear 17 to rotate. The third drive mechanism includes a first drive port, a second drive port 18, a drive prism 19, and a fourth drive mechanism. The first drive port is located on the fourth bevel gear 17, the second drive port 18 is located on the clamping seat 8, and the drive prism 19 is rotatably disposed within the support through hole 5. The drive prism 19 passes through both the first drive port and the second drive port 18, and is slidably connected to the side wall of the first drive port. The fourth drive mechanism is mounted on the support frame 2 and is used to drive the two drive prisms 19 to rotate synchronously. The system includes a third cavity, a sixth bevel gear 21, and a rotating mechanism. The third cavity is located within the support frame 2. A fifth bevel gear 20 is rotatably mounted on the side wall of the third cavity near the drive prism 19, and is fixedly connected to the adjacent drive prism 19. The sixth bevel gear 21 is rotatably mounted on the inner top wall of the third cavity and meshes with the fifth bevel gear 20. The rotating mechanism is mounted on the support frame 2 and drives the sixth bevel gear 21 to rotate. The rotating mechanism includes a second handwheel 22 and a third connecting rod. The second handwheel 22 is rotatably mounted on the support frame 2, and the third connecting rod is fixedly mounted between the second handwheel 22 and the sixth bevel gear 20. Specifically, the rotation of the second handwheel 22 can drive the sixth bevel gear 21 to rotate. At the same time, the meshing of the sixth bevel gear 21 with the fifth bevel gear 20 drives the drive prism 19 to rotate. Thus, the sliding engagement of the drive prism 19 with the first drive port drives the fourth bevel gear 17 to rotate. Furthermore, the meshing of the fourth bevel gear 17 with the third bevel gear 16 drives the third bevel gear 16 with the second threaded rod 15 to rotate. This facilitates the movement of the clamping block 9 through the rotation of the second threaded rod 15, thereby facilitating the further clamping and fixing of the actuator body 4 through the cooperation of the clamping block 9 with the support frame 2.

[0064] In this embodiment, the operator places the actuator body 4 between two clamping seats 8. The operator then rotates the first handwheel 14, which drives the second bevel gear 13 to rotate. Simultaneously, the meshing of the second bevel gear 13 with the first bevel gear 11 drives the first connecting rod 12 and the first threaded rod 10 to rotate. This facilitates relative movement of the clamping seats 8 through the threaded engagement of the first threaded rod 10 with the clamping seats 8, allowing the clamping seats 8 to clamp and fix the sidewalls of the actuator body 4. The operator then rotates the second handwheel 22, which drives the sixth bevel gear 21 to rotate. Simultaneously, the sixth bevel gear... The meshing of the fifth bevel gear 20 with the drive prism 19 causes the drive prism 19 to rotate. This, in turn, causes the fourth bevel gear 17 to rotate through the sliding engagement of the drive prism 19 with the first drive port. Furthermore, the meshing of the fourth bevel gear 17 with the third bevel gear 16 causes the third bevel gear 16 with the second threaded rod 15 to rotate. This facilitates the movement of the clamping block 9 through the rotation of the second threaded rod 15. This allows the clamping block 9 to further clamp and fix the actuator body 4 through the engagement of the clamping block 9 with the support frame 2. Afterward, the operator controls the electric push rod 3 to work, raising the height of the support frame 2, thereby adjusting the height of the actuator body 4.
