Heavy truck hub shell size detection machine

Abstract

The invention relates to the field of wheel hub shell detection, and discloses a heavy truck hub shell size detection machine. The machine comprises a main equipment rack (8), a workbench rack (9) isarranged on the main equipment rack (8), a workbench main air cylinder (11) and a main air cylinder column (12) are arranged on the workbench rack (9), a workbench (15) is arranged on the workbench main air cylinder (11) and the main air cylinder column (12), and a lower detection head (18) is arranged on the workbench (15); a vertical rack (29) is arranged on the main equipment rack (8), a movable arm mechanism (24) is arranged on the vertical rack (29), and an upper shaft shoulder detection head (21) and an upper detection head (23) are arranged on the movable arm mechanism (24). The heavy truck hub shell size detection machine has the advantages that the detection precision of the hub shell is improved, and therefore the quality of the hub shell is improved.

Description

technical field [0001] The invention relates to the field of detection of wheel hub shells, in particular to a size detection machine for heavy-duty truck wheel hub shells. Background technique [0002] At present, from the perspective of the automobile industry, the number of heavy-duty trucks is growing steadily. At the same time, with the wave of "Industry 4.0" based on the Internet of Things and information technology, the manufacturing of automobiles and their parts is gradually developing towards intelligent manufacturing. Heavy-duty trucks ( "Heavy truck" for short) intelligent manufacturing of hub bearings has become an inevitable trend. Application number CN201610640586.7 discloses a forging process for heavy-duty truck oversized hubs. The technology of automatic comprehensive detection of the assembly line for the hub shell shoulder and inner diameter of heavy-duty trucks is at a relatively advanced level in China, and there is even no research and development by ...

AI Technical Summary

Problems solved by technology

When inspecting the hub shell of heavy trucks, one can only rely on manual inspection of the internal shaft shoulder size and inner aperture size of the heavy truck hub shell. This kind of inspection has many obvious shortcomings. Manual inspection cannot achieve the corresponding accuracy. The efficiency is extremely low, high output cannot be guaranteed, and there will be many complicated factors in manual inspection. At the same time, the failure rate of the entire product may be increased due to insufficient precision, and it is easy to cause immeasurable losses to the enterprise. Now, for heavy truck hub spherical shells and The detection mechanism for automatic assembly bearings is relatively lacking in China at present, so it is urgent to develop a comprehensive detection machine for the shoulder and inner diameter of the heavy-duty truck hub shell to cooperate with the truck assembly line.
