Hydraulic radial drilling machine column locking principle

The basic principle of rocker drill column locking is that the main shaft of the rocker drill machine tool runs as the du transmission system of the main shaft of the machine tool, the feed operation of the rocker drill dominates the longitudinal feed of zhi axis, and the vertical rod is locked from the rocker arm to the rocker arm of the rocker drill.
The machine tool spindle box realizes all levels of transmission system, feed and operation of the machine tool spindle. The rotation speed range of the machine tool spindle is 25-2000r/min, with a total of 16 levels. According to the centralized operation handwheel of the transmission system, it can be realized. The feed range of the machine tool spindle is 0.04-3.2mm/r, with a total of 16 levels, which can be realized according to the centralized operation handwheel of the transmission system.
The rocker arm rises and falls and clamps. The rocker arm rises and falls by the upper motor of the vertical rod, and the screw nut transmission system realizes the rocker arm rises and falls. Among them, the rising and falling nut is equipped with a safety nut, so that the rocker arm cannot fall down for no reason.
The clamping of the rocker arm is realized by hydraulically driven prismatic block. After clamping, the prismatic block is self-locking device. After the rocker arm raises or lowers the clamping action, the rocker arm is independently clamped and is installed on the hydraulic cylinder. The electrical switch is adjusted.
The spindle box of the machine tool and the vertical rod are clamped. The clamping of the spindle box and the vertical rod of the machine tool are both hydraulically driven. The two actions can be carried out together or separately. The selection button is the button on the control panel of the spindle box of the machine tool. The left is the independent clamping of the vertical rod and the right is the independent clamping of the main guide shaft box.
