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 mechanical laser radar and a counterweight method for the same. The mechanical laser radar comprises rotary load and counterweight panels. The rotary load is used for being connected with a motor shaft of the mechanical laser radar and comprises a reflecting mirror surface and counterweight surfaces, and the axis of the motor shaft penetrates the counterweight surfaces; the counterweight panels are used for adjusting dynamic balance of a scanning control module, are connected with the counterweight surfaces of the rotary load or are formed by the counterweight surfaces of the rotary load, a plurality of counterweight points for welding counterweight objects are arranged on the counterweight panels and are arranged around a circumference at intervals, and the axis of the motor shaft is used as the circle center of the circumference. The mechanical laser radar and the counterweight method have the advantages thatunfixed counterweights are dynamically welded at positions to be subjected to counterweight processing, accordingly, the high precision can be guaranteed, requirements on artificial experience can belowered, and consumption of labor hours can be reduced; the problems due to fixing glue adding working procedures in the traditional counterweight fixing modes can be solved.

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...
