Self-lubricating drilling machine drilling bit capable of achieving position and direction adjustment

Abstract

The invention discloses a self-lubricating drilling machine drilling bit capable of achieving position and direction adjustment. The drilling bit comprises a bearing fixedly installed on a drilling machine, wherein a bearing cavity is formed on a lower surface of the bearing in a downward opening mode, a supporting block is slidably installed on a top wall of the bearing cavity, a connecting blockis fixedly arranged on a lower surface of the supporting block, first grooves which are symmetrical in the left-right direction are formed on a left wall and a right wall of the bearing cavity, and first sliding cavities are formed on sides, away from the supporting block, of the first grooves. The drilling bit is advantaged in that the position of the drilling bit can be quickly adjusted, rotation of a rotary rod is matched with rotation of an upper rotary table so that the drilling bit can drill an inclined hole or a straight hole on an inclined face, functions of the drilling bit are increased, and a working range is wider; an electromagnet and the spring realize automatic feeding of the drilling bit, the function of adding the lubricating liquid during drilling is simply and conveniently achieved through a switch valve, and drilling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of parts, components or accessories of machine tools, in particular to an automatic lubricating drill bit capable of adjusting position and direction. 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 structure of the drilling machine is simple, and the machining accuracy is relatively low. It can drill through holes, blind holes, replace special tools, expand, countersink, ream, or tap. At present, the drill bits of most drilling machines cannot be moved, and can only be used in the axial direction. Rotation and feed movement, mainly by adjusting the position of the workpiece to perform drilling, adjustment and fixation take a lot of time, and manual feeding is required, the operation needs to be ...

Problems solved by technology

The structure of the drilling machine is simple, and the machining accuracy is relatively low. It can drill through holes, blind holes, replace special tools, expand, countersink, ream, or tap. At present, the drill bits of most drilling machines cannot be moved, and can only be used in the axial direction. Rotation and feed movement, mainly by adjusting the position of the workpiece to perform drilling, adjustment and fixation take a lot of time, and manual feeding is required, the operation needs to be suspended when adding lubricating oil, the efficiency is relatively low, and generally only It can drill holes on flat workpieces and has a small scope of application. The present invention clarifies a device that can solve the above-mentioned problems
