The radial arm drilling machine has a beautiful appearance, and the overall layout is well-balanced and coordinated; it adopts mechanical speed change, mechanical locking, and easy operation; the rocker arm automatically lifts and lowers; the structure is reliable and the manufacturing is excellent, which ensures the durability of the machine tool accuracy. Radial drilling machine withdrawing arm drill is a kind of hole processing equipment, which can be used for drilling, reaming, boring, tapping and trimming of end faces and other forms of processing. According to the classification of the clamping structure of the machine tool, radial drills can be divided into hydraulic radial drills and mechanical radial drills. Among various types of drilling machines, radial drills are convenient and flexible to operate, have a wide range of applications, and are typical, especially suitable for single-piece or Mass production of hole processing with porous large parts is a common machine tool in general machining workshops.
Radial arm drilling machine The radial arm drilling machine is mainly composed of a base, an inner column, an outer column, a rocker arm, a headstock, and a worktable. The inner column is fixed at one end of the base, and an outer column is sleeved on the outside of the base, and 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 main rod and the outer column are connected as a whole, 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 spindle box is a composite component, which is composed of the main drive motor, the spindle and the spindle drive mechanism, the feed and speed change mechanism, and the operating mechanism of the machine tool. The spindle box is installed on the horizontal guide rail of the rocker arm, and can be operated by a hand wheel to move it along the paint arm on the horizontal guide rail.
