Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of mechanical equipment, and in particular to a rotating device with an arc-shaped guide rail. Background Art
[0002] Existing linear guides can basically only meet the needs of linear motion. However, when rotary welding, rotary non-destructive testing, rotary cutting, rotary spraying and other operations are required for pipelines, as well as for industrial automation production lines, such as cycle assembly, cycle flow, and cycle assembly, linear guides are required to achieve arc motion to meet the needs of motion and transmission. However, arc guide products are expensive and have a limited radius of curvature, which usually cannot meet actual needs. Generally, other transmission mechanisms are required to achieve the desired motion. However, after adding the transmission mechanism, the overall mechanism is loaded, resulting in more energy loss, lower precision, and increased noise. In view of this, the inventors have studied and designed a rotating device with an arc guide. Summary of the invention
