Description

technical field [0001] The invention relates to a cross hole drilling machine. Background technique [0002] Cross hole drilling machine is a kind of drilling machine, which is mainly used to process cross holes on the workpiece, that is, two drilling holes that intersect vertically in the same plane. According to different structures, currently known drilling machines can be divided into single-drilling drilling machines and multi-drilling drilling machines. The single-drill drilling machine has a simple structure and relatively simple operation. However, if the cross hole is to be drilled on the shaft workpiece, it must be divided into two operations, that is, after drilling a hole for the first time, it is manually turned over to the second hole and completes the drilling process of the second hole. Therefore, using a single-drilling machine to drill a cross hole must be manually operated, and the operation is cumbersome, it is difficult to ensure the vertical intersect...

Problems solved by technology

In this way, the two drills must rotate at the same time when they are working, and it is easy to cause the two drills to collide when drilling the cross hole. In practical applications, it is generally protected by setting a limit protection mechanism, and the cross is completed by half-processing. Hole processing, the operation process is more cumbersome, and the structure is more complicated
