Description

Technical Field

[0001] The utility model belongs to the technical field of mandrel processing, and in particular relates to a mandrel bidirectional drilling mechanism. Background Art

[0002] When the mandrel is processed, it needs to be drilled, and the mandrel is drilled by the rotating drill bit contacting the mandrel, thereby performing drilling processing on the mandrel.

[0003] Existing, when the mandrel is being drilled, it is necessary to clamp and fix the mandrel by a clamp to prevent the mandrel from moving during drilling and causing deviations in the angle of the lifting drilling, which would result in failure of the mandrel drilling. However, when the mandrel is clamped and fixed by the clamp, it is generally necessary to manually rotate the threaded rod to drive the two sets of clamps closer to each other and clamp the mandrel between the two sets of clamps. After the drilling process is completed, it is necessary to manually rotate the threaded rod again to drive the two sets of clamps away from each other, thereby releasing the clamping of the mandrel. As a result, when drilling the mandrel, workers are required to repeatedly rotate the threaded rod to clamp or release the mandrel, which makes it more troublesome to fix the mandrel, greatly reducing the efficiency of the mandrel drilling process.
