The upper part of the inclined support plate assembly is a working installation support surface. The V-shaped support assembly is installed on the right side of the working installation support surface on the inclined support plate assembly and is connected to the working installation support surface as a whole.

The arc-shaped positioning boss in the positioning mandrel component in the utility model can quickly accurately limit the position of the rocker arm blank workpiece. During specific processing, the processing efficiency of the inclined oil hole on the rocker arm blank workpiece is greatly improved. However, the above-mentioned heavy-duty loader rocker arm inclined oil hole processing tooling cannot clamp and suspend the two ends of the rocker arm during the clamping process, which makes the processing process more limited. At the same time, the clamping process is slow and the efficiency is low. Therefore, it is necessary to provide a rocker arm processing fast positioning tooling to solve the above problems.
