Drilling machine

Abstract

The invention relates to a drilling machine. The drilling machine comprises a base, an elevating upright column, a movable part, a rotary part, a drill bit, a clamp base and a clamping workpiece part.The clamp base is fixedly connected to one side of the base. The clamping workpiece part is rotatably connected to the upper part of the clamp base and comprises a bottom circular disk, a middle circular column and a location board, all of which are orderly and fixedly connected from the bottom to the top. A location clamp mechanism enabling a workpiece to be located and clamped is arranged on the location board. Two sides of the location board are equipped with drill bushings used for guiding the drill bit. The upper part of the clamp base is equipped with a location mechanism used for locating the clamping workpiece part and a locking mechanism used for locking the clamping workpiece part. The drilling machine has the following beneficial effects: as for a workpiece which needs symmetric drilling on two sides, the workpiece is not required to be located secondarily so that machining precision and efficiency are increased.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to a drilling machine. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. During the machining process, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and make the tool rotate (main movement). The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates. [0003] For some workpieces, it is necessary to symmetrically drill holes on both sides of the workpiece, which requires repeated positioning of the...

Problems solved by technology

[0003] For some workpieces, it is necessary to drill holes symmetrically on both sides of the workpiece, which requires repeated positioning of the workpiece, which is time-consuming and laborious, and the two positionings will cause positioning errors and processing errors, which will affect the processing accuracy and efficiency.
