Description

Technical Field

[0001] This utility model relates to the field of excavator support ring production technology, and specifically to a correction device for hydraulic excavator support rings. Background Technology

[0002] Currently, in the production process of hydraulic excavator support rings, after the ring is rounded, axial and radial misalignment is a common problem, directly affecting subsequent welding quality and overall machine assembly accuracy. Traditional correction methods rely mainly on manual operation, using simple tools such as cross struts for manual adjustment. This method not only requires a high level of skill and experience from the operators, but the correction process is also cumbersome, inefficient, and often requires repeated adjustments, resulting in high rework rates and production costs. Furthermore, manual correction suffers from poor consistency, making it difficult to ensure that the misalignment of the support ring is controlled within the allowable range (usually required to be less than 1mm), which in turn affects the forming quality of the X-groove during robotic welding and even the flatness of the top cover plate during X-frame assembly. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a correction device for hydraulic excavator support rings. This device corrects axial and radial misalignment of the support rings after the ring-circling process is completed, solving the problems of slow efficiency and difficulty in manual correction, and improving the production efficiency and stability of excavator support rings.
