A radial drilling machine

Abstract

The invention belongs to the drilling machine field, and in particular relates to a radial drilling machine. A workbench of the radial drilling machine is fixedly arranged at one end of a base, an internal column is fixedly arranged at the other end of the base, an external column is sleeved on the internal column, a rocker arm sleeve is arranged on one end of a rocker arm, the rocker arm sleeve is sleeved on the outer side of the external column, the rocker arm sleeve and the external column form a lead-screw-and-screw-nut fit structure through a rocker arm lifting lead screw and a lifting screw nut, which are used in a matched manner; a column clamping device and a rocker arm lifting safety device are driven by a gearbox body arranged on top of the external column; an opening is formed in the outer end part of the rocker arm sleeve on one end of the rocker arm, a rocker arm clamping device is arranged at the end part, busbars are respectively arranged on the upper and lower sides of the rocker arm, and the busbars adopt the form of hyperbolic curve; a spindle gearbox is mounted on a rocker arm guide rail of the rocker arm, and a main transmission electromagnetic clutch is arranged in the spindle gearbox. With the adoption of the radial drilling machine, the purposes of increasing performance, simplifying structure, facilitating manufacturing, usability, saving energy and facilitating operation are realized.

Description

technical field [0001] The invention relates to the field of drilling machines, in particular to a radial drilling machine. Background technique [0002] Radial drilling machine is a kind of hole processing equipment, which can be used for various forms of processing such as drilling, reaming, reaming, tapping and scraping end faces. The clamping structure of each part of the radial drilling machine can be divided into hydraulic structure and mechanical structure. The radial drilling machine is convenient and flexible to operate, has a wide range of applications, and has typical hole processing performance. It is especially suitable for large holes with holes in single-piece or batch production. Hole processing of small, medium and small parts is a common machine tool in general machining workshops. [0003] As shown in Figure 1(b), the radial drilling machine is mainly composed of base 1, outer column 8, rocker lifting gearbox 9, spindle gearbox 15, workbench 23, tradition...

AI Technical Summary

Problems solved by technology

[0007] Because the traditional rocker arm 25 lower side bus bars of the traditional radial arm drilling machine are all ascending straight lines 27, this will increase the height of the traditional rocker arm guide rail 26 on the traditional rocker arm 25 in space. In order to ensure the normal processing height, it is necessary to reduce the traditional internal The height of the column root 108 reduces the height of the traditional inner column root 108 to 480mm, resulting in a reduction in the rigidity of the inner and outer columns
