The basic principle of locking the rocker drill column is that the operation of the main shaft of the rocker drill machine tool is the operation of the Du transmission system of the main shaft of the machine tool. The rocker drill gives the longitudinal feed of the operating shaft, and the rocker drill rocker arm is locked on the vertical rod.
The spindle box of the machine tool realizes the transmission system, feed and operation of the machine tool spindle at all levels. The speed range of the machine tool spindle is 25-2000r / min, with a total of 16 levels. The centralized operation of the handwheel can be realized according to the transmission system, and the feed range of the machine tool spindle is 0.04-3.2mm/r, with a total of 16 levels. The centralized operation of the handwheel can be realized according to the transmission system.
The rocker arm rises, falls and clamps. The rise and fall of the rocker arm is driven by the motor at the upper end of the vertical rod and driven by the lead screw nut transmission system to realize the rise and fall of the rocker arm. A safety nut is installed on the rising and falling nut, so that the rocker arm can not fall off without reason.
The clamping of rocker arm is realized by hydraulic driving prism block. After clamping, the prism block is self-locking device. After the action of rocker arm raising or lowering clamping is completed, the rocker arm is clamped independently and adjusted by the electrical switch installed on the hydraulic oil cylinder.
The spindle box and vertical pole of the machine tool are clamped. The spindle box and vertical pole of the machine tool are 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, in which the left is the independent unclamp of the vertical pole and the right is the independent unclamp of the main axle box.
