[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 7 As shown, a multi-angle rotation device includes a mounting frame 6, a device for driving the mounting frame 6 to rotate in a circle, and a device for driving the mounting frame to rotate up and down. The device for driving the mounting frame 6 to rotate in a circle includes a support arm 4, on which a rotating gear 3 is provided, and the rotating gear 3 is connected to the second driving motor in a transmission manner. A rotating arm housing is connected to the front of the support arm, and the front of the rotating arm housing is connected to the mounting frame in a rotational manner through a rotating shaft 7. A rotating arm housing is connected to the front of the support arm 4, and the front of the rotating arm housing is installed in the mounting frame 6 through a rotating shaft 7, and the rotating shaft 7 is arranged parallel to the rotating gear 3. The rotating shaft is arranged parallel to the rotating gear, and when the rotating gear rotates in a circle, the support arm, the rotating arm housing and the rotating shaft all rotate in a synchronous circle, thereby driving the mounting frame to rotate in a circle. The mounting frame rotates around the rotating shaft when rotating up and down.

[0032] like Figures 2 to 4 As shown, the connection mode between the mounting frame 6 and the swing arm housing is as follows: a mounting slot 61 is provided in the middle of the mounting frame 6, the front of the swing arm housing is located in the mounting slot 61, and the two sides of the front of the swing arm housing are rotatably connected to the mounting frame 6 through the rotating shaft. The swing arm housing includes a left swing arm housing 51 and a right swing arm housing 52, the left swing arm housing 51 is provided with a left mounting end 511 in front, the right swing arm housing 52 is provided with a right mounting end 521 in front, and the rotating shaft passes through the left mounting end 511, the right mounting end 521 and the mounting frame 6.

[0033] like Figures 4 to 7 As shown, the device that drives the mounting frame to rotate up and down is a pull rod and its transmission system. Specifically, the support arm 4 is hollow inside and is provided with a support rod 1, the front of the support rod 1 is connected to the mounting frame 6, the support rod 1 is connected to the mounting frame 6, and a rack 2 is provided behind the support rod 1. The rack 2 controls the forward and backward movement of the support rod 1, and the rotating gear 3 controls the rotation of the mounting frame 6. Figure 5 As shown, a pull rod 82 is hinged in front of the support rod 1 , and a fixed shaft 81 is provided in the mounting groove 61 of the mounting frame 6 , and the pull rod 82 is connected to the fixed shaft 81 .

[0034] It should be noted that the rotating shaft and fixed shaft in the present invention are only used to distinguish the names, and are not intended to limit their functions. The pull rod and the fixed shaft can also be rotatably connected, and the fixed shaft and the mounting bracket can also be rotatably connected.

[0035] The rotating shaft and the fixed shaft are located at different heights of the cross section of the mounting frame, the rotating shaft is located above the fixed shaft, and the fixed shaft is located in front of the rotating shaft. The rotating shaft or the fixed shaft can be set at an eccentric position of the cross section of the mounting frame. In this embodiment, it is preferred that both the rotating shaft and the fixed shaft are set at an eccentric position of the cross section of the mounting frame, so that when the pull rod pulls the fixed shaft, the mounting frame can rotate up and down around the rotating shaft.

[0036] like Figure 7 As shown, the fixed shaft 81 is located at an eccentric position of the horizontal interface of the mounting frame. When the pull rod moves forward and backward, the mounting frame 6 is driven to rotate up and down with the rotating shaft 7 as the axis. When the pull rod is in the original state, the mounting frame faces upward, and the pull rod and the fixed shaft are in position B. When the pull rod moves forward and backward, such as when the pull rod and the fixed shaft are in position C, the mounting frame 6 is driven to rotate downward with the rotating shaft as the rotation axis, and then the pull rod moves forward to drive the mounting frame to rotate upward.

[0037] like Figure 4 , 6 and Figure 7 As shown, the support rod 1 is arranged in the support arm 4, and the support arm 4 is hollow inside. The support rod 1 extends forward along the length direction of the support arm 4, and is hinged with the pull rod 82 when extending into the rotating arm housing. The pull rod 82 is arranged in the rotating arm housing and connected to the fixed shaft 81 in the mounting groove 61. The support rod and the pull rod are both arranged along the length direction of the support arm and the rotating arm housing, and the pull rod is connected to the fixed shaft after passing through the rotating arm housing. The pull rod 82 is arranged below the left mounting end 511 and the right mounting end 521, and the support rod and the pull rod are respectively arranged to pass through the support arm and the rotating arm housing, so that the support arm and the rotating arm housing that control the circumferential rotation of the mounting frame and the support rod and the pull rod that control the up and down rotation of the mounting frame will not interfere with each other, and can also be synchronized.

[0038] The rack 2 is connected to the first drive motor, and the rotating gear 3 is connected to the second drive motor. The drive motor is not shown in the figure. The first drive motor is a forward and reverse bidirectional rotating motor.

[0039] The utility model provides a multi-angle rotating device which can realize circular rotation and up-and-down rotation of a mounting frame, thereby providing a more realistic simulation scene for a device to be tested or calibrated on the mounting frame and improving the calibration accuracy of the device to be calibrated on the mounting frame.

[0040] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
