Mechanical manufacturing drilling machine

Abstract

The invention discloses a machine manufacturing drilling machine with a fixed base; bolt holes are fixedly formed in the four corners of the upper end face of the fixed base. The upper end face of thefixed base is fixedly connected with a supporting column. A workpiece fixing device is fixedly connected to the middle of the side end face of the supporting column. The workpiece fixing device comprises a movable fixing plate, a threaded hole, a limiting column, a connecting column, a threaded clamping groove, a threaded column, a fixed clamping groove, piston clamping grooves, a fixed main bodyand a movable groove; the movable groove is formed in the upper end surface of the fixed main body; the movable fixing plate is slidably connected to the interior of the movable groove through the connecting column; the threaded hole is formed in the upper end face of the movable fixing plate, the limiting column is slidably connected to the upper end face of the movable fixing plate, the fixed clamping groove is formed in the side, away from the movable groove, of the upper end face of the fixed main body, and the piston clamping grooves are formed in the two sides of the interior of the fixed clamping groove. The drilling machine can provide good fixing performance for the workpiece, and meanwhile the safety performance of the device is greatly improved.

Description

[0001] The invention relates to the field of mechanical manufacturing, in particular to a drilling machine for mechanical manufacturing. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, 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, blind holes, and replace special tools. , can be expanded, countersink, reamed or tapped. During the processing, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and rotate the tool. The characteristic of the drilling machine is that the workpiece is fixed and the tool Do rotary motion, but the mechanical manufacturing drilling machine currently used has the following defects: firstly, when the drill bit rotates, it is easy to...

[0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, 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, blind holes, and replace special tools. , can be expanded, countersink, reamed or tapped. During the processing, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and rotate the tool. The characteristic of the drilling machine is that the workpiece is fixed and the tool Do rotary motion, but the mechanical manufacturing drilling machine currently used has the following defects: firstly, when the drill bit rotates, it is easy to cause waste material to splash and cause unnecessary casualties; Good and inconvenient to operate
