The servo motor will shake and impact, which is easy to be damaged, and the vibration noise will become louder and louder.

[0004] Therefore, a servo motor anti-vibration device is proposed. Utility Model Content

[0013] Through the cooperation between the first limit sleeve and the second limit sleeve, the bolts at the connection between the servo motor and the equipment can be limited, and the second limit sleeve can be locked in position by the cooperation between the self-locking block and the self-locking rod, so that the distance between the first limit sleeve and the second limit sleeve is at a fixed value, so that the bolt cannot rotate, thereby achieving the problem of thread loosening of the bolts at the connection between the servo motor and the equipment due to vibration, ensuring the tight and firm connection between the servo motor and the equipment, and improving the shockproof ability of the servo motor.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a servo motor anti-vibration device, such as Figure 1-4 As shown, it includes a support plate 1, and the outer wall of the support plate 1 is provided with a fixed plate 2; the bottom of the fixed plate 2 is rotatably connected to a first limiting sleeve 3, the bottom central position of the support plate 1 is screwed with a first screw rod 4, the top of the first screw rod 4 is rotatably connected to a moving block 5, a moving plate 6 is integrally formed on the outer wall of one side of the moving block 5, and the top of the moving plate 6 is rotatably connected to a second limiting sleeve 7, an annular slide rail is provided on the top of the first limiting sleeve 3 and the bottom of the second limiting sleeve 7, a self-locking block 8 is integrally formed on the outer wall of the other side of the moving block 5, and a support cover 9 is fixedly connected to the outer wall of the support plate 1 on the side away from the fixed plate 2 by screws, and the support cover 9 is away from the support plate A second screw rod 10 is screwed together at the central position of the outer wall on one side of 1 through a threaded engagement, and one end of the second screw rod 10 is rotatably connected to a limiting cover 11. A guide rod 12 is welded on the outer wall on one side of the limiting cover 11. There are two guide rods 12 in total, and the two guide rods 12 pass through the support cover 9. A self-locking rod 13 is embedded on the outer wall on the other side of the limiting cover 11. A spring 14 is fixedly connected between one end of the self-locking rod 13 and the inner wall of the limiting cover 11 through an adhesive. A servo motor 15 and a device 16 are arranged at one side of the support plate 1. The servo motor 15 is located above the device 16, and the servo motor 15 and the device 16 are fixedly connected by a bolt 17.

[0022] It should be noted that since most of the existing servo motors are installed and fixed by bolts, and since the servo motor will generate vibration when working, the vibration will be transmitted to the connection between the servo motor and the equipment, thereby causing the bolts at the connection to gradually loosen, so that the connection between the servo motor and the equipment is not tight enough. In this embodiment, the first limit sleeve 3 and the second limit sleeve 7 cooperate with each other, so as to limit the bolt 17 at the connection between the servo motor 15 and the equipment 16, and use the self-locking block 8 and the self-locking rod 13 to lock the second limit sleeve 7 in position, so that the distance between the first limit sleeve 3 and the second limit sleeve 7 is at a fixed value, so that the bolt 17 cannot rotate, thereby achieving the problem of thread loosening of the bolt 17 at the connection between the servo motor 15 and the equipment 16 due to vibration, thereby ensuring that the servo motor 15 and the equipment 16 are tightly and firmly connected, and improving the shockproof ability of the servo motor 15.

[0023] Specifically, in this embodiment, this scheme mainly includes a first limiting sleeve 3 and a second limiting sleeve 7, and the servo motor 15 and the device 16 are fixedly connected by bolts 17. When performing anti-vibration operation, the support plate 1 is placed on one side of the bolt 17, and the first limiting sleeve 3 at the bottom of the fixed plate 2 is sleeved on the bolt head of the bolt 17, and then the first screw 4 is rotated. Through the screwing connection between the first screw 4 and the support plate 1, and through the rotation between the first screw 4 and the moving block 5, the first screw 4 pushes the moving block 5 to move upward, and the moving plate 6 and the self-locking block 8 on the moving block 5 move upward synchronously. When the second limiting sleeve 7 on the moving plate 6 moves to the bottom of the threaded sleeve on the bolt 17, the second limiting sleeve 7 is rotated so that the hexagonal groove on the second limiting sleeve 7 can be sleeved on the outside of the threaded sleeve, and the moving plate 6 continues to move upward, and the second limiting sleeve 7 After the limiting sleeve 7 is sleeved on the threaded sleeve on the bolt 17, the position of the bolt 17 is limited, and the second screw rod 10 is rotated. Through the threaded connection between the second screw rod 10 and the support cover 9, and through the rotational connection between the second screw rod 10 and the limiting cover 11, the second screw rod 10 pushes the limiting cover 11 to move, and the self-locking rod 13 on the limiting cover 11 contacts the self-locking block 8. After the self-locking rod 13 is compressed, the spring 14 is compressed, and the self-locking rod 13 that is not in contact with the self-locking block 8 is limited on the outside of the self-locking block 8, thereby limiting the position of the self-locking block 8, thereby avoiding the problem of loosening of the thread of the bolt 17 caused by the movement of the first limiting sleeve 3 and the second limiting sleeve 7, and avoiding the problem of loosening and falling off of the bolt 17 connection between the servo motor 15 and the equipment 16 caused by the vibration of the servo motor 15, thereby improving the shockproof ability of the servo motor 15.

[0024] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the fixed plate 2 and the movable plate 6 are both perpendicular to the support plate 1 , and a through hole is provided at the bottom of the movable plate 6 near the lower inner side of the second limiting sleeve 7 .

[0025] In this embodiment, by making the fixed plate 2 and the movable plate 6 horizontal, the first limit sleeve 3 and the second limit sleeve 7 can be sleeved on the bolt 17, so as to limit the two ends of the bolt 17 and prevent the bolt 17 from loosening. By setting the through hole, the screw in the bolt can pass through the movable plate 6.

[0026] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a through groove is provided on the outer wall of one side of the support plate 1 near the outer side of the moving block 5, and the moving plate 6 and the support plate 1 are slidably connected via a slider and a sliding groove.

[0027] In this embodiment, the through groove is provided to provide space for the movement of the moving block 5 , and the sliding connection is utilized to ensure the stability of the movement of the moving plate 6 on the supporting plate 1 .

[0028] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the tops of the first limiting sleeve 3 and the second limiting sleeve 7 are provided with hexagonal grooves matching the bolts 17 .

[0029] In this embodiment, the first limiting sleeve 3 and the second limiting sleeve 7 can be sleeved on the bolt head and the threaded sleeve on the bolt 17 .
