Small-scale vertical drilling machine

Abstract

The invention discloses a small-scale vertical drilling machine which comprises a base. A stand column and a workbench are fixedly connected to the top of the base. A clamp is installed on the top of the workbench. The stand column and a connection sleeve are connected through a bolt, the stand column penetrates through the connection sleeve, and the connection sleeve is connected with a supporting arm through a flange. Grooves are formed in the two sides of the stand column. A rotating rod is installed inside the stand column. A pulling plate is arranged inside the connection sleeve and slides in the grooves. The pulling plate is connected with the rotating rod through threads, and the rotating rod penetrates through the pulling plate. The supporting arm is provided with a sliding groove, and a sliding block is arranged in the sliding groove. The sliding block is connected with a connection rod through a bolt. One end of the supporting arm is connected with a drill body. The drill body comprises a drilling barrel, an operating lever and a drill bit, wherein one end of the drilling barrel is connected with the sliding block through the connection rod, the drilling barrel is connected with the supporting arm through a bearing, the operating lever is arranged on one side of the drilling barrel, and the drill bit is arranged at the bottom of the drilling barrel. The small-scale vertical drilling machine is convenient to operate, the workbench does not need to be frequently adjusted when the drilling positions are adjusted and multiple holes are drilled, and the labor intensity is relieved.

Description

technical field [0001] The invention relates to the technical field of machine tool processing, in particular to a small vertical drilling machine. Background technique [0002] Vertical drilling machines are often used in machinery manufacturing and repair factories to process holes in small and medium-sized workpieces. As a kind of drilling machine, vertical drilling machine is also a relatively common metal cutting machine tool. It has the characteristics of wide application and high precision, and is suitable for batch processing. Before the vertical drilling machine is processed, the clamping position of the workpiece on the worktable must be adjusted first, so that the centerline of the processed hole is aligned with the tool axis. In the traditional method of processing, the workpiece is fixed, and the spindle rotates in the sleeve and feeds axially with the sleeve. The workbench and headstock should be adjusted along the column guide rails to accommodate workpieces...

AI Technical Summary

Problems solved by technology

If multiple holes are processed on the workpiece, the position of the workbench needs to be adjusted several times. When machining inclined holes on the workpiece, it is not easy to fix it on the workbench. The drill bit can only drill downward along the axis in one direction. inconvenient
