Problems solved by technology

[0002] At present, most of the rotation of the two-dimensional tracking turntable adopts mechanical limit, such as figure 1 As shown, the existing mechanical limit structure is basically realized by the collision between the limit protrusion 2 (lever) installed on the rotating body 1 and the limit assembly 4 (bumper) installed on the fixed base 3. , when the required rotation range exceeds 360°, it is necessary to set two-level limit protrusions with different lengths to cooperate with two buffers to complete the large-scale rotation limit of the rotating body. When using two-level limit, two buffers The two stoppers respectively limit the two limit protrusions with different lengths, so that the volume of the fixed base needs to be increased, and the two buffers are misplaced, which results in a substantial increase in the complexity and volume of the overall limit mechanism structure , which brings great difficulties to assembly and debugging

Embodiment Construction

[0020] When the existing limit mechanism rotates more than 360°, the two-stage limit mechanism needs to cooperate to realize the limit of the two-dimensional tracking turntable. This results in a large increase in the complexity and volume of the limit structure, which is difficult for assembly and debugging. bring great difficulty.

[0021] Aiming at the problems in the working process of the limit mechanism of the existing two-dimensional tracking turntable, the present invention proposes a super 360° rotation limit mechanism of the two-dimensional tracking turntable with small volume, simple structure and easy operation.

[0022] Combine now figure 2 and image 3 To describe the structure in detail:

[0023] The limit mechanism includes a limit protrusion 2 arranged on the rotating body 1 of the two-dimensional tracking turntable and a limit assembly 4 arranged on the fixed base 3 for blocking the limit protrusion 2 so as to prevent the rotating body from rotating. , th...

Abstract

The invention belongs to the technical field of optical measurement, and in particular relates to a super 360-degree rotating limiting mechanism of a two-dimensional tracking turntable. The mechanism comprises a limiting bulge arranged on a rotating body, and a limiting assembly that is arranged on a fixed base and used for blocking the limiting bulge so as to stop the rotating of the rotating body. The mechanism is characterized in that the limiting assembly comprises two rotating baffle blocks that are positioned on the movement rail of the limiting bulge and are mounted to the fixed base by hinging; the two rotating baffle blocks can only rotate in one direction and rotate in opposite directions so as to limit the rotating of the rotating body. With the adoption of the super 360-degree rotating limiting mechanism of the two-dimensional tracking turntable, the problem that the complexity and size of the existing limiting mechanism are greatly raised when the two-dimensional tracking turntable rotates over 360 degrees, and large difficulty is brought to assembling and debugging, is solved.
