Description

Technical Field

[0001] The invention belongs to the technical field of parts transfer assembly lines and relates to a wheel frame part and a processing method thereof. Background Art

[0002] In the existing mechanical processing field, the transfer of processed parts is usually carried out by manipulators or manual handling. For the manual handling method, there are problems such as long and uncontrollable handling time and high labor costs. In addition, in order to avoid safety accidents, it is usually necessary to shut down the equipment before handling, which is not conducive to improving production efficiency. Although the high degree of automation of the manipulator handling method ensures production efficiency, it also causes high production costs. In addition, during use, in order to avoid interference between the manipulator and other equipment, it is necessary to increase the distance between adjacent equipment, resulting in low factory space utilization. Therefore, in actual factories, track drive motors and track shafts are often arranged and installed, and wheel frame parts on the shafts are connected to the drive motors and the parts to be transferred by sliding sleeves. However, after long-term use, the track shafts are inevitably deformed, making the distance between the track drive motor and the track shafts unfixed or deflected, so that the wheel frame parts are subjected to large tensile stress or rotational stress, which makes them easy to damage and affects their use.
