Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to an automatic grinding machine for rectangular aluminum tubes, which is suitable for efficient and automated grinding of the surface of rectangular aluminum tubes. Background Technology

[0002] Rectangular aluminum tubes are widely used in construction, automotive, aerospace, and other fields, and their surfaces require polishing to meet smoothness requirements. Traditional polishing methods mostly rely on manual operation or semi-automatic equipment, which suffers from time-consuming manual loading and unloading and adjustment of workstations. Although some automated polishing equipment exists, its structure is complex, the coordination between the fixing and feeding mechanisms is insufficient, and it lacks precise adjustment of polishing depth. Therefore, there is an urgent need for an automatic polishing machine for rectangular aluminum tubes with high integration, high automation, and flexible adjustment. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

A lead screw fixing mechanism is provided in the polishing area of ​​the polishing mechanism for clamping and moving the rectangular aluminum tube to the polishing station. A pushing mechanism is provided at one end of the lead screw fixing mechanism for pushing the rectangular aluminum tube into the lead screw fixing mechanism for clamping.

[0005] The other end of the lead screw fixing mechanism is provided with a discharge mechanism for conveying the polished rectangular aluminum tube to a designated position.
