Introduction to radial drilling machine

Introduction to radial drilling machine

drilling machine in which the spindle box can move on the radial arm and rotate around the column with the radial arm. The rocker arm can also move up and down along the column to adapt to the processing of workpieces with different heights. Smaller workpieces can be installed on the workbench, and larger workpieces can be directly placed on the machine base or the ground. Radial drilling machines are widely used in single piece and small and medium-sized batch production to process the holes of workpieces with large volume and weight. The radial drilling machine has a wide processing range, which can be used to drill various screw holes, threaded bottom holes and oil holes of large workpieces. The main variants of radial drilling machines are sliding seat type and universal type. The sliding type radial drilling machine is made by changing the base of the basic radial drilling machine into a sliding seat. The sliding seat can move along the guide rail of the bed to expand the processing range. It is suitable for boiler, bridge, locomotive and rolling stock, shipbuilding and other industries. In addition to vertical and rotary movements, the rocker arm of the universal rocker drilling machine can also move horizontally. The spindle box can make tilt adjustment on the rocker arm to adapt to the processing of various parts of the workpiece. In addition, there are car type, wall type and digital control radial drilling machines

drilling machine is a kind of hole processing equipment, which can be used for drilling, reaming, reaming, tapping, scraping end faces and other forms of processing. According to the use and structure classification, drilling machines can be divided into vertical drilling machines, bench drilling machines, multi hole drilling machines, radial drilling machines and other special drilling machines. Among all kinds of drilling machines, radial drilling machines are easy to operate, flexible, and typical in a wide range of applications. They are especially suitable for hole processing of single piece or batch production of large-scale parts with multiple holes, which play a synergistic effect across business departments. They are common machine tools in general machining workshops

at present, the major domestic radial drilling machine manufacturers are: Shenyang Zoje machine tool, Shenyang Machine Tool Group, Shandong Lunan precision machine, Shandong Xiangyu Machine Tool Co., Ltd. These manufacturers are old factories with long production history, reliable quality and many years of reputation

main structure of radial drilling machine

radial drilling machine is mainly composed of base, inner column, outer column, rocker arm, headstock and workbench. The inner column is fixed at one end of the base, and the outer column is sleeved outside it. The outer column can rotate 360 degrees around the inner column. One end of the rocker arm is a sleeve, which is sleeved on the outer column to move up and down. Since the screw rod is connected with the outer column, and the lifting nut is fixed on the rocker arm, the rocker arm cannot rotate around the outer column, but can only rotate around the inner column together with the outer column. The headstock is a composite part, which is composed of the main drive motor, the spindle 6, the spindle drive mechanism, the feeding mechanism during the experiment of the test block with the same size, the speed change mechanism, the operating mechanism of the machine tool, etc. The headstock is installed on the horizontal guide rail of the rocker arm and can be operated by the hand wheel to move along the rocker arm on the horizontal guide rail

motion form of radial drilling machine

when processing, the spindle box is fastened on the radial guide rail by a special tightening device, while the outer column is fastened on the inner column, and the radial arm is fastened on the outer column, and then drilling processing is carried out. During drilling, the drill bit performs rotary cutting and longitudinal feeding at the same time. Its motion form is:

(1) the main motion of the radial drilling machine is the rotation of the spindle

(2) feed although the wire they provide is not 100% environmentally friendly movement for the longitudinal feed of the spindle

(3) auxiliary movements include: the rocker arm moves vertically along the outer column, the headstock moves along the length of the rocker arm, and the rocker arm rotates around the inner column together with the outer column
