Problems solved by technology

[0003] In the prior art, most of the standard screws are manually cut off on site, screwed into the counterweight hole of the rotating load, and fixed with fixing glue. On the one hand, in the process of cutting the standard screws, the weight is completely dependent on manual Experience and feeling, there are large errors and waste of time and materials. On the other hand, because the fixing glue also has a certain weight, adding the fixing glue will affect the adjusted dynamic balance and reduce the dynamic balance performance. If it is reworked, then It is necessary to add cumbersome procedures such as removing the fixing glue, which will inevitably cause greater waste of manpower and material resources

Abstract

The invention relates to the technical field of laser radar, and discloses a mechanical laser radar and its counterweight method, which includes: a rotating load used to connect with the motor shaft of the mechanical laser radar, and the rotating load includes a reflective mirror surface and a counterweight surface, The axis of the motor shaft passes through the counterweight surface; the counterweight panel used to adjust the dynamic balance of the scanning control module, the counterweight panel is connected with or formed by the counterweight surface of the rotating load, and the counterweight panel is set There are a plurality of counterpoints for welding counterweights, and the plurality of counterweights are spaced around a circle centered on the axis of the motor shaft. The mechanical laser radar and its counterweight method provided by the present invention can dynamically weld the unfixed counterweight weight to the place to be counterweighted, while ensuring high precision, reduce the requirement for manual experience and the consumption of labor hours; avoid the traditional The problems introduced by the process of adding fixing glue in the counterweight fixing method.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a mechanical laser radar and a counterweight method thereof. Background technique [0002] In the mechanical laser radar, there are inevitably mechanical rotating parts, so that the single laser beam scans a surface, and the accuracy of its mechanical rotation directly affects the measurement accuracy and related performance of the mechanical laser radar. The key factor of service life, therefore, in the production process of mechanical laser radar, accurately adjusting the dynamic balance of rotating parts is the top priority of producing high-performance, long-life mechanical laser radar, and improving the efficiency of dynamic balance adjustment is An important part of increasing productivity. [0003] In the prior art, most of the standard screws are manually cut off on site, screwed into the counterweight hole of the rotating load, and fixed with fixing glue. On the one...
