Problems solved by technology

[0002] In the general processing technology, it is difficult to process the transverse hole on the inner wall, especially for the hole on the inner wall of a large workpiece. In the case of relatively high precision requirements, it is difficult to achieve the required precision in general processing.

There is no fixed device in the general transverse inner hole processing, especially when machining the transverse inner hole of the cylindrical structure (the inner hole perpendicular to the main axis of the cylindrical structure), usually only one time Machining a transverse inner hole results in very low machining efficiency, and the positional accuracy of the machined hole is also relatively low; as shown in the technical solution disclosed in No. ZL99214615.1, "Inner Wall Side Hole Processing Device" in the Chinese patent document , the structure of the processing device involved in this patent document is as follows: the depth of the tool entering the workpiece is adjusted by the spindle head coupling of the machine tool, and two bevel gears are used in the device to mesh the rotation of the motor in the horizontal direction into Rotation of the drill bit in the vertical direction

The structure of this utility model patent can only drill one hole at a time in application, and the position accuracy of the processed hole is relatively low, and it is generally only suitable for the horizontal hole processing of small workpieces in processing

This kind of device is very inconvenient when processing holes. It cannot be adjusted according to the shape of the workpiece and the position of the hole during processing. In the case of one clamping, it cannot simultaneously process horizontal inner holes with asymmetrically distributed positions.
