Description

Technical Field

[0001] The invention relates to the field of drilling facilities, in particular to a drilling and boring device with adjustable center height. Background Art

[0002] A drilling machine is a machine tool that mainly uses a tool to machine holes on a workpiece. The working principle of a drilling machine is to drive the tool to perform rotary cutting through the rotation of the spindle, and at the same time use the feed mechanism to make the tool perform linear feed along the axial direction, so as to machine the required holes on the workpiece, and the tool on the drilling machine can be replaced with a drill bit or a boring tool as needed to perform drilling, boring, etc.

[0003] When processing some workpieces such as reducers, a drill press is often used to drill holes on both sides of the reducer for easy connection. However, in the use of existing drill presses, due to the large diameter of the reducer, the tool cannot complete the drilling operation on both sides of the reducer at one time. Therefore, it is necessary to manually loosen the clamped reducer and adjust the position of the reducer after drilling a hole on one side, and then drill a hole on the other side. The drilling is performed in two steps. The adjustment error during the operation easily causes the holes on both sides to be out of alignment, which seriously affects the quality of drilling and boring. Summary of the invention
