Description

Technical Field

[0001] This utility model relates to the field of rotating platforms, specifically a rotating device with a range of ±180°. Background Technology

[0002] Rotary devices used in radar and optoelectronic fields typically require the ability to achieve large-angle rotation of ±180°. However, during debugging or operation, software crashes and motor malfunctions often lead to excessive movement and motor stall, damaging the rotating disk and causing significant losses to equipment manufacturers and users. This invention aims to provide a ±180° rotating device with dual electrical and mechanical limit protection and elastic buffering to absorb stall impact energy. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to realize a ±180° rotation device with over-limit electromechanical dual limit safety protection and reduce the impact damage caused by motor stall.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A device capable of rotating ±180° includes a base, a direct drive motor, a motor driver, a rotating disk, a limit slider assembly, an elastic buffer assembly, a limit block, a mounting base, a photoelectric switch, a sealing top cover, a V-shaped sealing ring, and a sealing side cover. The direct drive motor is located in the middle of the upper part of the base, the limit slider assembly is located on one side of the direct drive motor, two sets of elastic buffer assemblies are located at both ends of the limit slider assembly, the mounting base and the photoelectric switch are located outside the limit slider assembly, the rotating disk is located above the direct drive motor, and the limit block is located below the rotating disk.

[0006] Preferably, the rotating disk and the limiting block are assembled separately, so that the rotating disk is protected first when the rotation exceeds the limit.

[0007] Preferably, the sealed top cover can be disassembled to facilitate the integration of the direct drive motor, limit slider assembly, elastic buffer assembly, mounting base, and photoelectric switch inside.

[0008] Preferably, the V-shaped sealing ring can be used in conjunction with the upper load to achieve waterproof and dustproof protection for the internal equipment.

[0009] Preferably, the limiting slider assembly includes a linear guide rail, a limiting sliding block, a rubber damping pad, and a photoelectric switch contact. The limiting sliding block is placed on the upper side of the linear guide rail slide, the rubber damping pad is placed on both sides of the limiting sliding block, and the photoelectric switch contact is placed on the end side of the limiting sliding block, ensuring that the sliding is more stable and the resistance is smaller when rotating beyond ±180°.

[0010] Preferably, the limiting sliding block has inclined surfaces on both sides, which, combined with rubber shock-absorbing pads, can reduce the upward reaction force of the linear guide rail when it contacts the elastic buffer component, thereby protecting the linear guide rail.

[0011] Preferably, the elastic buffer assembly includes a spring seat, a pressure spring, a spring guide shaft, and a guide shaft baffle. The pressure spring and the spring guide shaft are sequentially placed in the spring seat, and the guide shaft baffle is placed outside the spring guide shaft and fixed to the spring seat.

[0012] Preferably, the over-limit power-off safety protection is achieved by the photoelectric switch contact piece contacting the photoelectric switch, and the impact when the direct drive motor stalls is reduced by the soft contact between the limit sliding block and the elastic buffer component and the spring damping, so as to ensure that the rotating device achieves over-limit mechanical safety protection.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During operation, the direct drive motor drives the rotating disk and the limit block to push the limit sliding block to slide left and right, achieving a rotational movement of ±180°. The photoelectric switch contact plate activates the photoelectric switch to achieve over-limit power-off safety protection. The soft contact between the rubber shock-absorbing pad on the limit sliding block and the elastic buffer component, as well as the spring damping, reduces the impact when the direct drive motor stalls, ensuring that the rotating device achieves over-limit mechanical safety protection.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying contradictory importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically limited.

[0023] See Figure 1 A ±180° rotating device includes a device base 1, a rotating disk 4, a sealing top cover 10, a V-shaped sealing ring 11, and a sealing side cover 12. The rotating disk 4 is fastened to the inner rotating disk of the direct drive motor 2 by screws. After the limit slider assembly 5, the elastic buffer assembly 6, the mounting base 8, and the photoelectric switch 9 are integrated, the sealing top cover 10 is fastened to the device base 1 by screws, and the V-shaped sealing ring 11 is placed on the sealing surface of the sealing top cover 10. After the motor driver 3 and other load-bearing equipment are installed, the sealing side cover 12 is fastened to the device base 1 by screws.

[0024] See Figure 2 A ±180° rotation device further includes a direct drive motor 2, a motor driver 3, a limit slider assembly 5, an elastic buffer assembly 6, a limit block 7, a mounting base 8, and photoelectric switches 9. The limit slider assembly 5 is placed on one side of the direct drive motor 2, and its fixed guide rail is fastened to the device base 1 with screws. Two sets of elastic buffer assemblies 6 are respectively placed on both sides of the limit slider assembly 5. The spring seat 61 is fastened to the device base 1 with screws. The mounting base 8 is placed on the side of the limit slider assembly 5 and connected to the device base 1. Two photoelectric switches 9 are respectively fixed on the left and right sides of the mounting base. The limit block 7 is fixed on the outer side of the bottom of the rotating disk 4. The motor driver 3 is fixed inside the device base 1.

[0025] During operation, the direct drive motor 2 drives the rotating disk 4 and the limit block 7 to push the limit sliding block 52 to slide left and right, achieving a rotational movement of ±180°. The photoelectric switch contact 54 contacts the photoelectric switch 9 to achieve over-limit power-off safety protection. The soft contact between the rubber shock-absorbing pad 53 on the limit sliding block 52 and the elastic buffer component 6, as well as the spring damping, reduces the impact when the direct drive motor 2 stalls, ensuring that the rotating device achieves over-limit mechanical safety protection.

[0026] See Figure 3 The limiting slider assembly 5 includes a linear guide rail 51, a limiting sliding block 52, rubber shock-absorbing pads 53, and photoelectric switch contacts 54. The limiting sliding block 52 has inclined surfaces on both sides and is fixed to the upper end of the linear guide rail 51 slide. The rubber shock-absorbing pads 53 are respectively placed on both sides of the limiting sliding block 52 and fixed by screws and adhesive. The photoelectric switch contacts 54 are placed on both sides of the end face of the limiting sliding block 52 and fastened by screws.

[0027] See Figure 4 The elastic buffer assembly 6 includes a spring seat 61, a pressure spring 62, a spring guide shaft 63, and a guide shaft baffle 64. After the pressure spring 62 is inserted into the hole in the spring seat 61, the spring guide shaft 63 is sequentially inserted into the inner hole of the pressure spring 62 and extends out along the rear hole of the spring seat 61. The guide shaft baffle 64 is fitted into the spring guide shaft 63 and fixed to the spring seat 61. When the rotating device stalls and exceeds the limit, the limiting sliding block 52 contacts the spring guide shaft 63 and is acted upon by the pressure spring 62 to absorb and buffer the impact energy, thereby reducing damage to the rotating device.

[0028] The aforementioned direct drive motor 2 is used to drive the load to rotate. The motor driver 3 is used to control the direct drive motor 2 to perform rotation according to the instructions of the terminal system. The photoelectric switch 9 is used to give a power-off signal to the rotating device when the photoelectric switch contact 54 contacts the photoelectric switch 9 when the rotating device exceeds the limit. The direct drive motor 2 and the motor driver 3 are connected for power supply and communication. The motor driver 3 and the photoelectric switch 9 are respectively connected to the external power supply system and the terminal control system to realize power supply, signal reading, and instruction interaction.

[0029] In summary, in this embodiment, during operation, the direct drive motor 2 drives the rotating disk 4 and the limiting block 7 to push the limiting sliding block 52 to slide left and right along the linear guide rail 51, achieving a rotational movement of ±180°. The photoelectric switch contact 54 contacts the photoelectric switch 9 to achieve over-limit power-off safety protection. The soft contact between the rubber shock-absorbing pad 53 on the limiting sliding block 52 and the elastic buffer component 6, as well as the spring damping, reduces the impact when the direct drive motor 2 stalls, ensuring that the rotating device achieves over-limit mechanical safety protection.
